A cartographic analysis of Shi and Lian…Dou in Mandarin Chinese

Abstract Shi and lian … dou/ye can both be used as focus constructions in Mandarin Chinese. The current paper aims to investigate the shi and lian … dou/ye constructions within the framework of Syntactic Cartography. The two constructions share very similar syntactic distributions; however, shi and lian are not in the same syntactic position, or more precisely, the former is located higher than the latter. The two constructions mark various foci, namely, adjunct focus, predicate focus, subject focus, and complement focus. In terms of the focus meaning, they express foci of different types, namely, shi introduces the exclusive focus and lian signals the inclusive focus, which is retained in their lexical meanings during the process of grammaticalization of the two words. Both shi and lian can occur at the sentence-initial position and the sentence-internal position. The current research agrees with the previous studies that the sentence-initial lian-XP serves as topics while the sentence-internal lian-XP functions as foci. This paper claims that the sentence-initial shi-phrase also expresses topics and further argues that the sentence-initial shi-phrase marks topic foci whereas the sentence-initial lian-phrase marks focus topics which both carry the [Topic] and [Focus] features but differ in the feature strength. It is concluded that shi can be analyzed on a par with lian in Mandarin Chinese.

PUBLIC INTEREST STATEMENT
Topics and foci play an important role in many branches of linguistics, including syntax, semantics, and pragmatics. In Mandarin Chinese, shi and lian . . . dou are always regarded as focus markers. The aim of the current paper is to explore a syntactic account of the two constructions. It is observed that the shi and lian . . . dou constructions share very similar syntactic distributions and that the former's position is higher than that of the latter. The two constructions mark various foci and express different focus meanings, namely, the former expresses the exclusive focus and the latter the inclusive focus. The different focus meanings are retained in their lexical meanings during the process of grammaticalization. It is claimed that the sentence-initial shi-phrase also expresses topics. It is further argued that the sentence-initial shi-phrase marks topic foci, whereas the sentence-initial lian-phrase marks focus topics. Therefore, shi can be analyzed on a par with lian in Mandarin Chinese.

Introduction
The study of focus has long fascinated Chinese linguists, the views on which have remained controversial. One of the controversies is the divided opinion as to which words can carry the [Focus] feature or serve as the focus marker. Xu and Li (1993) argued that only unstressed shi can function as the focus marker; Fang (1995) claimed that in addition to shi, lian can also mark foci; Liu and Xu (1998) proposed that lian expresses topic foci; Zhao and Sun (2005) and Jiang and Wei (2010) among others claimed that such adverbs as zhiyou, cai, dou, ye, etc. are also used to express foci. Fang (1995) proposed three criteria for markers as shown below and claimed that the Chinese language only has two focus markers, i.e. shi and lian. Given the fact that lian and dou/ye always co-occur when employed to express foci, lian . . . dou/ye is also regarded as the focus marker.
(1) A marker generally does not carry content meaning and thus cannot be stressed.
(2) The function of a marker is to mark as foci the elements following them, hence the phonological prominence on those elements.
(3) A marker is the optional element in a sentence, the ellipsis of which does not affect the grammaticality of the sentence. (Fang, 1995, p. 281) Badan and Del Gobbo (2015) investigated the even-construction and claimed that the initial lianconstruction marks topics and the internal lian-construction marks foci. Their research sheds some light on this paper. Xiong (2017) conducted a cartographic analysis of the even-sentence, the analysis of which this paper partially agrees with.
Despite the unreached consensus on the number of focus markers in Chinese, it is generally agreed that shi-sentences and lian . . . dou/ye are both focus constructions. Research abounds concerning the semantic analysis of dou and lian . . . dou; however, there is only a small amount of syntactic research. The syntax of shi-sentences has also been the topic of much discussion. 1 Nevertheless, few scholars have conducted a comparative study of the two constructions. He (2011) noted that the syntactic distributions of the shi and lian . . . dou constructions are very similar, yet her research is mainly a descriptive one with very little explanation of the syntactic derivation. Therefore, the current paper aims to analyze the shi and lian . . . dou constructions within the framework of Cartography and to explore whether there are any similarities between the two constructions in light of their very similar syntactic positions (see, Section 2 for more detail), providing a syntactic account of the two constructions.
The residue of the paper is organized as follows: Section 2 presents a brief description of the syntactic positions of the shi and lian . . . dou/ye constructions; Section 3 differentiates two types of foci the two constructions express and investigates the origin of the focus meaning; Section 4 conducts a cartographic analysis of the two constructions; Section 5 concludes the paper.

Syntactic positions of Shi and Lian . . . dou/ye constructions
The element following the focus marker shi is focalized and various foci can be signaled by shi, i.e. adjunct focus, predicate focus, subject focus, and complement focus. Shi can precede various adjunct foci, including time, location, instrument, manner, purpose, to name but a few. For reasons of space, only one example is given below as an illustration (cf. for more detail Shyu, 2016, pp. 548-556). 2 (4) 张三是在欧洲拿到博士学位的。 Zhangsan shi zai ouzhou nadao boshi xuewei de.
Zhangsan be in Europe obtain PhD degree DE 3 "Zhangsan obtained his PhD degree in Europe." It should be noted that shi and the following focalized element can also occur at the sentenceinitial position. For the sake of simplicity, the following example will suffice to illustrate the point. Shi can also emphasize verb phrases as exemplified below. However, in this case, shi and the focalized element cannot be preposed to the sentence-initial position, witnessed by the ungrammaticality of (6b). In addition, shi can emphasize the subject and the complement, subject to some restrictions. When the subject is emphasized, it can only occur at the sentence-initial position, as illustrated in (7). Similarly, When the complement is focalized, shi and the following element can only occur at the sentence-initial position, 4 as (8)  shi Aoman yu Pianjian Yuehan meiyou du-guo.
be Pride and Prejudice John not read-ASP "John has not read Pride and Prejudice." The description above demonstrates that shi is subject to some restrictions in terms of its syntactic distributions. The following presents the description of the lian . . . dou/ye construction.
Prior to the exemplification of the types of the focalized elements, it is important to describe the position of lian and the focused element. Shyu (1995) pointed out that "lian . . . dou/ye is limited to a preverbal position" (Shyu, 1995, p. 7). Lian can occur at the sentence-initial and the sentenceinternal position, but not the sentence-final position, as shown in (9) Shyu, 2016, pp. 567-572). As for adjunct focus, lian can be followed by various foci, including time, location, instrument, to name but a few. The adjunct focus can also occur at the sentence-initial position. For reasons of space, two examples are presented in (10)-(11) as an illustration.
I LIAN 11 yesterday happen robbery DOU not know "I didn't know that a robbery happened yesterday." Lian . . . dou/ye can also emphasize verb phrases as exemplified in (12). However, unlike shi, lian and the focused VP can be preposed to the sentence-initial position, as manifested in (13). Moreover, lian can also focalize the subject and the complement, subject to some restrictions. Similar to shi, the focalization of the subject is limited to the sentence-initial position, as illustrated in (14). It is also worth noting that the focalization of the complement leads to word order variation, i.e. the word order has changed from canonical SVO order to OSV and SOV, as manifested in (15a) and (15b) respectively. The description above demonstrates that the focus marker lian . . . dou/ye is also constrained in terms of the syntactic distributions. The description above leads to the observation that the shi and lian . . . dou/ye constructions share very similar syntactic distributions, as summarized in Table 1.

Exclusive focus and inclusive focus
The previous section demonstrates that the two markers shi and lian . . . dou/ye are highly similar in terms of their syntactic distributions. Nevertheless, the focus meanings expressed by the two constructions are different. König (1991, p. 33) claimed that focus particles can be classed into two groups: additive/inclusive particles and restrictive/exclusive particles. In Mandarin Chinese shi marks the exclusive focus (cf., Tsai, 2004, pp. 99-100;Xiong, 2017, p. 440) whereas lian . . . dou/ye marks the inclusive focus (cf., Liu & Xu, 1998, p. 251;He, 2011, p. 45;Xiong, 2017, p. 440). The exclusive focus marked by shi picks out one element of a set of alternatives, as illustrated in (16). As for the inclusive focus, Xiang (2008) argued that the lian . . . dou construction not only asserts that the least likely event is true but also "emphasizes that the alternatives to the least likely event, namely, the more likely ones, are also true" (Xiang, 2008, p. 241), as manifested in (17). 12 (16) 是张三通过了考试。 shi Zhangsan tongguo-le kaoshi.

Scalar implicature: Zhangsan is the least likely person to pass the exam.
This paper further claims that the exclusive focus and the inclusive focus are rooted in the lexical meanings of the two markers, supported by the diachronic evidence. It's generally believed that the copula shi is derived from the demonstrative shi, though the emerging mechanism has remained controversial (Liang, 2012, p. 44). Liang claimed that the copula shi is derived from the anaphoric demonstrative shi (ibid.), as illustrated below. but Heshi ZHI jade Sui Marquis ZHI pearl nine tripods cannot benefit people be not world ZHI good treasures SFP "But He Shi's jade, Marquis Sui's pearl, and the nine tripods (ding) cannot benefit people, so, in terms of the world, they are not excellent treasures. (Johnston, 2010, p. 649)" (19) 她最佩服的人是她的导师。 ta zui peifu de ren shi tade daoshi.
she most admire DE person be her supervisor "The person who she admires most is her supervisor." (Liang, 2012, pp. 44-45) Shi and Han (2013) investigated the grammaticalization of copulas and described the grammaticalization cline of shi, as shown in (20). Shi is derived from demonstratives whose function is to take its reference from a preceding word or phrase and thus specifies a particular reference, which expresses the exclusive focus when shi develops itself into a focus marker.
(20) adjectives > the transitional usage as verbs, nouns, etc. > pronouns > copulas > focus markers (Shi & Han, 2013, p. 5) Similarly, the inclusive meaning of lian is retained through its historical development. Xing (2004) studied the grammaticalization of lian and pointed out that "lian is probably one of the grammatical morphemes that has undergone the most complex syntactic change" (Xing, 2004, p. 87) and summarized the syntactic changes as shown in Table 2.
Lian was primarily used as a verb meaning "to unite/ connect", as shown in (21). Xing (2004) pointed out that "in Tang-Song texts, lian is found to express the meaning of 'inclusiveness'" (Xing, 2004, p. 85), as illustrated in (22). In this period lian cannot be used for accentuation. In the Qing texts, lian is commonly used as a focus marker expressing "the value of the focused expression to a set of alternatives (König, 1991: 32)" (Xing, 2004, p. 86), as exemplified in (23). if count place receive Taoism person including 1sg then is thirty people "If (one) counts the Taoists at the West Mountain including/and me (there) are thirty people." (23) 众人轰然一笑连贾珍也撑不住笑。 zhong-ren hong-ran yi-xiao, lian Jia Zhen ye cheng-bu-zhu xiao.
everyone suddenly laugh even name also neg-help laugh "Every one burst into laughter; even Jia Zhen laughed." (Xing, 2004, pp. 83-86) It can be seen above that the grammaticalization of shi and lian supports the claim that the exclusive focus marked by shi and the inclusive focus marked by lian . . . dou/ye are rooted in their lexical meanings. This is in line with Hopper's (1991) principle of persistence, one of the five principles of grammaticalization, that when a linguistic form is grammaticalized from lexical words to function words "some traces of its original lexical meanings tend to adhere to it" (Hopper, 1991, p. 22).

A cartographic analysis
Ever since the Split-CP Hypothesis, the cartographic approach has become one of the main currents in the generative syntactic research. Syntactic Cartography analyzes the hierarchical order of functional categories in the CP domain, otherwise known as the left periphery, aiming to draw a map, as detailed as possible, of the functional projections in the peripheral domain of the clause. The attributes and projection positions constitute key points of the Cartography. Rizzi (1997) initiated the cartographic line of research and argued that the CP layer can be split into ForceP, TopP, FocP and FinP which are all higher than IP. He proposed the following structure for the complementizer system.  (Rizzi, 1997, p. 297) Belletti (2004) analyzed the cartography of the clause's (IP) internal low area and pointed out "a strict parallelism between the clause-internal vP/VP periphery and the clause-external one in the CP left periphery" (Belletti, 2004, p. 25), as shown in (25). (25) IP . . . TopP* . . . FocP . . . TopP* . . . vP/VP (ibid.) Paul (2005) applied Belletti's (2004) proposal about the cartography of the low IP area to Mandarin Chinese and partially confirmed the parallelism, as manifested in (26). (26) IP > inner TopicP > "even" focusP > vP (Paul, 2005, p. 129) The aim of this paper is to provide a syntactic account of the shi and lian . . . dou constructions. They are both generated by movement. The reasoning goes as follows. (27b) and (28b) demonstrate that the lian-phrase and the shi-phrase can be moved across the clausal boundary. However, the ungrammaticality of (27d) and (28c) indicates that the two phrases cannot move out of an island, meaning that the movement is sensitive to island effects which are regarded as the signature of A-bar movement. (27c) shows that the lian-phrase cannot move across the clausal boundary to the matrix preverbal position, which means that the phrase undergoes movement of a different kind, not A-bar movement but A-movement. 14 In the ensuing discussion, further evidence which confirms that the sentence-initial lian-phrase and shi-phrase undergo A-bar movement and that the sentence-internal lian-phrase undergoes A-movement will be presented. (27)  The two kinds of lian-XP are both derived through movement, yet they undergo different types of movement. The sentence-initial lian-XP undergoes A-bar movement (Shyu, 1995, pp. 79-84;Badan & Del Gobbo, 2015, p. 44) whereas the sentence-internal lian-XP undergoes A-movement (Shyu, 1995, pp. 135-138;Badan & Del Gobbo, 2015, p. 44), confirmed by the following evidence.
The first piece of evidence concerns Reconstruction Effect which holds only for A'-chains but not for A-chains (Chomsky, 1993, p. 37) and thus diagnoses A-bar movement. The ungrammaticality of (29a) due to the failure of co-indexation between Zhangsan and taziji indicates that there is no Reconstruction Effect, 15 while the success of co-indexation indicates that Reconstruction Effect is observed in (29b). "Even the book about himself 1 Zhangsan 1 threw away." (Shyu, 1995, p. 136) Another piece of evidence relates to the fact that the resumptive pronoun cannot co-refer with lian-XP at the sentence-internal position (Shyu, 1995, pp. 90-93;Badan & Del Gobbo, 2015, p. 43) while it is allowed with the sentence-initial lian-XP (Shyu, 1995, p. 139;Badan & Del Gobbo, 2015, p. 44), as manifested in (30). Even Mali Lisi all very like her "Lisi likes even Mary." (Badan & Del Gobbo, 2015, pp. 43-44) The current research agrees with Badan and Del Gobbo's (2015) claim that the "sentence-initial lian is located in a topic position" (Badan & Del Gobbo, 2015, p. 44), whereas "in the case of sentenceinternal lian . . . dou, focalization has occurred" (ibid.), supported by the following evidence.
The sentence-initial lian-XP can be followed by topic markers, as illustrated in (31a). Moreover, a pause is obligatorily required between the sentence-initial lian-phrase and the subject when the former is not marked by the topic marker. The topic marker is not allowed for the sentence-internal lian-XP, witness the ungrammaticality of (31b). Nevertheless, (31b) is grammatical or acceptable on the condition that there are commas after Zhangsan and the topic marker a respectively or the sentence is read with pauses after Zhangsan and a, as evidenced by (31c) in which the topic marker ma and a occur after Zhangsan and lian-XP respectively. The contrast in grammaticality between (31b) and (31c) is clear; however, the grammaticality of (31c) does not invalidate the argument that the sentence-internal lian-XP cannot be followed by topic markers in that (31c) indicates a different structure from that of (31b). (31c) will be analyzed in the ensuing discussion. Zhangsan TOP LIAN this-CL book TOP DOU read-ASP "As for Zhangsan, he has read even this book." The head of the FocP is not lian but rather dou/ye in that the omission of lian does not affect the focus interpretation, as manifested in (32a)-(32b). However, dou cannot be omitted, otherwise the focus interpretation is eliminated, and the sentence even becomes ungrammatical, as (32c) shows. Following Badan and Del Gobbo (2015, p. 42), this paper claims that lian Merges with the focalized element at the base-generated position of the element and is labeled as LianP 17 by the labeling algorithm (Chomsky, 2013, p. 43). Dou is the head of FocP and it never moves. 18 Mention was made of the fact that the sentence-initial lian-XP, located in the topic position in the left periphery, undergoes A-bar movement, and the sentence-internal lian-XP, an instance of focalization, undergoes A-movement. Lian Merges with yuyinxue "phonetics" at the Complement position of the verb and then the LianP moves to [Spec, FocP], deriving (33), as illustrated in (34) Given the fact that lian expresses the inclusive focus and the inclusive meaning is retained through its historical development as pointed out in Section 3 and that the sentence-initial lianphrase marks topics, this paper argues that the sentence-initial lian-phrase is a focus topic, carrying both [Topic] feature and [Focus] feature. This has already been noted by Liu and Xu (1998, p. 247) who claimed that lian is both a topic and a focus and is thus a topic focus. Nevertheless, this paper agrees with their claim but uses different terminology. The current paper claims that lian is a focus topic in that the [Topic] and [Focus] features lian carry differ in their strength, namely, the former is a strong feature while the latter is a weak feature. The reasons why the [Focus] feature is weak for the sentence-initial lian-phrase are twofold. For one thing, the omission of lian does not affect the focus interpretation; for another, it is dou that enables lian to obtain the scalar reading for the reason that the former, as a maximality operator, operates on the set evoked by the latter (Xiang, 2008, p. 242). This is also supported by the evidence of grammaticalization. Xing (2004) pointed out that ye "developed its scalar function earlier than lian" (Xing, 2004, p. 86).
In view of the fact that movement is driven by the strong feature, the landing site of lian-XP is [Spec, TopP] in the left periphery. Since lian must combine with dou/ye to obtain its scalar reading, the lian-phrase in (35) The analysis above well accounts for the ungrammaticality of (31b). The sentence-internal lian-XP undergoes A-movement and is moved to [Spec, FocP] with dou serving as the head of the FocP. No topic marker can intervene between the lian-XP and dou in that they are in a Spec-Head configuration and thus there is no position to accommodate the topic marker. Although the surface forms of (31b) and (31c) are highly similar, their structures are different. The reason why both the subject Zhangsan and the lian-phrase in (31c) can be followed by topic markers is that the two phrases are both moved to the left periphery and both of them are topics. (31c) can be derived based on (31a), i.e. the topicalization of the subject Zhangsan results in (31c), the syntactic structure of which is manifested in (37).

(40) 是这本书啊, 张三没读过。 shi zhe-ben shu a, Zhangsan mei du-guo. be this-CL book TOP Zhangsan not read-ASP "It is this book that Zhangsan has not read." The aforementioned evidence confirms that sentence-initial shi-phrase and sentence-initial lianphrase resemble each other: Both undergo A-bar movement and can be followed by topic markers.
The next question to be considered is whether shi and lian are in complementary distribution. It turns out that shi can co-occur with lian and thus they do not compete for the same syntactic position, or more precisely, the former is located higher than the latter, as manifested in (41).

LIAN Zhangsan be syntax DOU like
Lit: "*Even Zhangsan is syntax likes." Xiong (2017) proposed the following hierarchy for the case of the co-occurrence of shi and lian, as shown in (42) (Xiong, 2017, p. 446) This paper partially agrees with Xiong's (2017) analysis. As pointed out above dou is located at the Head position of FocP in that it is the omission of dou, rather than lian, that eliminates the focus interpretation, as shown in (32). Therefore, if lian heads the focus projection, the omission of lian should deprive the sentence of the focus interpretation. However, this prediction is not borne out.
Furthermore, this paper argues that the sentence-initial shi-phrase is also a topic. Badan and Del Gobbo (2010) noted that the lian-phrase is located lower than any topic, as illustrated in (43). Zhangsan PART even Xiaoyu all criticize PERF "As for Zhangsan, even Xiaoyu, he criticized." d. ??连小宇, 张三啊, 都批评了。 lian Xiaoyu j , Zhangsan i a, t i dou piping le t j .
even Xiaoyu Zhangsan PART all criticize PERF "Even Xiaoyu, as for Zhangsan, he criticized." 24 (Badan & Del Gobbo, 2010, pp. 83-84) (43) shows that the hierarchical order of topics is "Base generated Topic > Moved topic > lianphrase", which confirms the claim that shi-phrase and lian-phrase are both topics. Another two pieces of evidence are presented as follows. The first piece of evidence concerns Weak Crossover (WCO) effects. This paper, following Rizzi (1997, p. 292) and Badan and Del Gobbo (2010, p. 86), assumes that topics do not exhibit WCO effects. There are no WCO effects in (44) and therefore shi-phrase is a topic.
(44) 音乐, 是摇滚乐, 批评它的人都不喜欢听。 yinyue, shi yaogunyue i , piping ta i de ren dou bu xihuan ting t i . music be rock criticize it DE person DOU not like listen "As for music, it is rock that those who criticize it do not like listening to." Another piece of evidence concerns the co-occurrence with other foci, which is based on the assumption that multiple foci are unable to co-occur. Rizzi's (1997) seminal work on the structure of the left periphery proposes that "the Top Phrase is recursive, while the Foc Phrase is not" (Rizzi, 1997, p. 296). Since there is only one structural position for the focus, the focalization of two elements is excluded. The fact that the resumptive pronoun in (45b) can be coreferential with "Zhangsan" indicates that lian-phrase is a topic. This suggests that the shi-phrase is also a topic. The reasoning goes as follows. On the one hand, multiple topics are allowed whereas multiple foci are prohibited; on the other hand, as mentioned above lian-phrase is lower than any topic. Pan (2015) claimed that in Mandarin Chinese "TopP is higher than FocP whenever they co-occur" (Pan, 2015, p. 858). Since lian-phrase is a topic, shi-phrase must also be a topic; otherwise the grammaticality of (45a) would remain unexplained.
(45) a. 音乐, 是嘻哈乐, 连张三, 都不听。 yinyue, shi xihayue, lian Zhangsan, dou bu ting. music be hip-hop LIAN Zhangsan DOU not listen "As for music, it is hip-hop that even Zhangsan doesn't listen to." b. 音乐, 是嘻哈乐, 连张三, 他都不听。 yinyue, shi xihayue, lian Zhangsan i , ta i dou bu ting. music be hip-hop LIAN Zhangsan he DOU not listen "As for music, it is hip-hop that even Zhangsan doesn't listen to." The diagnostics above indicate that the sentence-initial shi-phrase is also a topic; shi heads a functional projection with a TopP as its complement. This is supported by the grammaticalization of copulas. Recall in Section 3 that shi, as Shi and Han (2013) noted, is grammaticalized into a focus marker. They also claimed that shi can further grammaticalize itself into a topic marker (Shi & Han, 2013, p. 7), with the cline of grammaticalization presented in (46). It should be noted that the focus marker shi and the topic marker shi can co-exist, supported by Hopper's (1991) principle of layering that when new layers emerge "the older layers are not necessarily discarded, but may remain to coexist with and interact with the newer layers" (Hopper, 1991, p. 22).
(46) adjectives > the transitional usage as verbs, nouns, etc. > pronouns > copulas > focus markers > (topic markers; Shi & Han, 2013, p. 9) Cross-linguistic evidence lends support to the grammaticalization from focus markers or copulas to topic markers. The Hebrew topic marker hu changed from a pronoun to a copula and then to a topic marker, as shown in (47). The claim that copulas can be used as both topic markers and focus markers is also confirmed by cross-linguistic evidence. Augustin (2007) claimed that in Swahili -ndi, which is topicalized from the copulas, can mark both foci and topics, as illustrated in (48)-(49) respectively.

No, my car broke down. (Augustin, 2007, p. 10) Moreover, the use of shi as topic markers is also attested in Chinese dialects. Wang and Xiong (2021) noted that the copula shi in Fuzhou dialect in Jiangxi province can be used as a topic marker. The copula shi marks as the topic the element preceding it in Fuzhou dialect, as (50) shows, different from its Mandarin counterpart. Liu (2016) claimed that the use of shi as both topic markers and focus markers are widely used in Suantang dialect of Jingzhou in Hunan province, as exemplified in (51).

(Liu, 2016, p. 95) The discussion above demonstrates that the sentence-initial shi-phrase and lian-phrase are both topics, which confirms the claim that shi can be analyzed on a par with lian. Moreover, the use of shi as topic markers demonstrates some parametric variation: shi precedes the element which it marks as the topic in Mandarin whereas shi follows the element which it marks as the topic in dialects.
Section 3 pointed out that the shi and lian . . . dou constructions have different focus interpretations, namely, the former expresses the exclusive focus whereas the latter expresses the inclusive focus. This seems to be controversial with the claim that the sentence-initial shi-phrase and lianphrase are both topics. However, recall that it is argued above that lian carries both [Topic] and [Focus] features and expresses the focus topic. Since shi can be analyzed on a par with lian, this paper argues that shi, akin to lian, also carries both [Topic] and [Focus] features. Yet the difference is that in terms of shi the [Focus] feature is the strong feature whereas the [Topic] feature is the weak feature. Therefore, this paper argues that shi marks the topic focus. The claim is supported by the following evidence. Liu and Xu (1998, p. 247) claimed that the topic focus (the element that has the function of both topic and focus) is usually signaled by topic markers which can either precede the element or follow the element. Shi-phrase can be followed by a topic marker which is a sentence-final particle (SFP). If the SFP is absent, a pause is obligatorily required, as exemplified in (52). They further proposed two criteria for the topic focus. For one thing, the comment following the topic focus cannot be omitted; for another, in sentences containing topic focus both the topic and the comment should be contrastive, as exemplified with Shanghai dialect in (53). Based on the two criteria, shi marks the topic focus for the reasons that the omission of the comment following shiphrase gives rise to the ungrammaticality of (54) and that the topic and comment in (55) can both be contrastive.

The diagnostics above indicate that the sentence-initial shi-phrase has the function of both topic and focus. The reason why the [Focus] feature is strong for the sentence-initial shi-phrase is that shi can express the exclusive focus in and of itself and the exclusive meaning is retained in its lexical semantics through its historical development. Given the fact that the syntactic diagnostics indicate that the sentence-initial shi-phrase expresses topics and that the topic must follow shi in Mandarin, shi takes a TopP as its complement. Recall that shi is located higher than lian as shown in (56), yet the reason why it is the case remains unclear. However, this can be accounted for if the sentence-initial shi-phrase and the sentence-initial lian-phrase are considered to be the topic focus and the focus topic respectively.

Recall that the topic focus marker can either precede or follow the element (Liu & Xu, 1998, p. 247). This also exhibits parametric variation: The topic focus marker mo in Shanghai dialect follows the element it marks as the topic focus whereas the topic focus marker shi and the focus topic marker lian in Mandarin precede the element. This is aligned with the parametric variation demonstrated by the use of shi as topic markers in Chinese dialects and Mandarin Chinese.
To recapitulate briefly, this section demonstrates that the sentence-initial lian-XP marks topics and the sentence-internal lian-XP marks foci and that the sentence-initial shi-phrase is also a topic which is located higher than the lian-topic. Therefore, shi can be analyzed on a par with lian. Given the fact that both shi and lian have the function of topic and focus, this paper argues that shi marks the topic focus whereas lian marks the focus topic. The sentence-initial shi-phrases and lianphrase exhibit parametric variation between Chinese dialects and Mandarin.

Conclusion
The current paper investigates the shi and lian . . . dou/ye constructions in the Chinese language. Shi and lian are always treated as focus markers and various foci can be marked by the two markers, i.e. adjunct focus, predicate focus, subject focus, and complement focus. The two markers share very similar syntactic distributions; nevertheless, they express different foci: Shi expresses the exclusive focus whereas lian signals the inclusive focus. Moreover, this paper claims that the different focus interpretations are rooted in the lexical meanings of the two markers as a result of the historical development.
The paper analyzes the two constructions within the framework of Cartography. The present research agrees with the previous studies that the sentence-initial lian-XP serves as topics while the sentence-internal lian-XP functions as foci. It is found that shi and lian are not in complementary distribution and that the former is located higher than the latter. The paper argues that the sentence-initial shi-phrase marks the topic focus while the sentence-initial lian-phrase expresses the focus topic, with the two phrases both carrying [Topic] and [Focus] features but differing in the feature strength. Meanwhile, the sentence-initial shi-phrases and lian-phrase demonstrate parametric variation between Chinese dialects and Mandarin Chinese. It is led to conclude that shi can be analyzed on a par with lian in Mandarin Chinese.
reshuffle the linear order of the sentence, which is not the case with pseudo-cleft sentences. Huang (1982, pp. 289-291;1990, p. 44) claimed that cleft sentences are formed by inserting the copula shi in front of the constituent and that the removal of shi does not affect the grammaticality and the meaning, as shown in (iii). Therefore, shen "God" appears at the sentence-initial position and (7) is formed by inserting shi in front of the subject. The same holds for (8) where the complement is preposed to the sentence-initial position.
However, the copula cannot be removed in pseudocleft sentences; otherwise, the equative function is lost and the sentences change into relative clauses. Huang (1982, p. 292) pointed out that sentences of this kind involve a structural dependency and that what appears before the copula is a free relative, as manifested in (iv). Pseudo-cleft sentences lie outside the purview of the paper.

I tomorrow want buy that book "I want to buy that book tomorrow." 6. Some may judge the sentence to be less natural when it is uttered out of the blue; however, the acceptability improves when the sentence is put in a context, as (8) shows. This can also be achieved when the contrastive element is added, as illustrated in (v). Another way to emphasize the complement is to employ pseudo-cleft sentences, as shown in (vi).
(v) 是《傲慢与偏见》约翰没有读过,不是《红楼 梦》。 as "even", it is observed that lian is not a complete equivalent of "even". As a result, in this paper, lian is glossed as LIAN. 12. Since the focus of this paper is to provide a syntactic account of the shi and lian . . . dou constructions, the semantic analysis will not be explored here. However, see, König (1991, pp. 60-119) for further discussion on the exclusive focus and inclusive focus and see, Xiong (2017, p. 440) for a brief semantic discussion of the inclusive focus and exclusive focus expressed by lian . . . dou and shi in Chinese. Also see, Xiang (2008, pp. 240-244) for the semantic analysis of the lian . . . dou construction. 13. Top* indicates that the topic phrases can be iterated. 14. The failure of the lian-phrase to move across the clausal boundary exhibits clausal boundedness which is a feature of A-movement. What distinguishes A-movement from A-bar movement is that A-bar movement can across an infinite number of CPs so long as locality constraints are observed while A-movement cannot cross any CPs, as exemplified in (vii (Rizzi, 2010, p. 20) However, it is not the case that Criterial Freezing is violated. The reasons are as follows. For one Rizzi (2006Rizzi ( , 2010 pointed out that the immediate kind of evidence for Criterial Freezing dating back to Lasnik and Saito (1984) is that a wh-phrase which satisfies the Q Criterion in the embedded interrogative cannot move to the main complementizer, witness the ungrammaticality of (xi). This piece of evidence connects the freezing principle with island effects. If the derivation of (35) [uTop] feature. The cyclic movement does not involve island effects; rather, the movement is more concerned with semantic interpretation. The phrase moves to [Spec, FocP] to obtain the focus reading in that dou as a maximality operator, operates on the set evoked by lian (Xiang, 2008).
Moreover, an anonymous reviewer remarked that the lian-phrase does not undergo movement to the topic position in (xii). But this sentence also has to undergo cyclic movement in order to get the scalar reading. It should be noted that wo "I" followed by the topic marker a is not the subject of the sentence but the topic. In this case, the lian-phrase is located in the topic position given that it can also be followed by a topic marker and that (xii) is grammatical under the condition that there is a pause between the lian-phrase and dou, which is phonologically realized as the topic marker ya, as shown in (xiii). This said, the lian-phrase is located above TP.

I TOP LIAN that three-CL book TOP DOU not give Zhangsan "As for me, even those three books, I did not give to Zhangsan." 22. On first reading the sentence, some may judge it to be less natural. However, the acceptability improves if the phonological prominence is put on Mali. 23. The authors disagree with Xiong's (2017) judgment on the grammaticality of (42b) in that xiaoshuo, a base-generated topic, is an Aboutness Topic which is supposed to be followed by the element providing some new information directly related to the topic. The authors believe that (xiv) is more natural than (42b).
novel be A Dream of Red Mansions LIAN Zhangsan DOU not read-ASP "As for novel, it is A Dream of Red Mansions that even Zhangsan has not read." 24. The original translation presented in (Badan & Del Gobbo, 2010, p. 84) is "Even Xiaoyu, as for Zhangsan, he didn't criticize." Here the translation is adjusted to the meaning of the Chinese sentence. 25. The topic marker and focus marker are glossed as shi 2 and shi 3 respectively in Liu (2016). Since the authors are not familiar with the pronunciation of the dialect, the pronunciation of this example cannot be provided.
