語法結(jié)構(gòu)--從句

 wwwijhyt圖書館 2013-05-17

內(nèi) 容 提 要

定語從句是由關(guān)系代詞和關(guān)系副詞引導(dǎo)的從句,其作用是作定語修飾主句的某個成分,定語從句分為限定性和非限定性從句兩種。狀語從句分為時間狀語從句,結(jié)果狀語從句,讓步狀語從句,原因狀語從句,條件狀語從句以及行為方式狀語從句。名詞從句包括主語從句,賓語從句,表語從句和同位語從句及there be句型。

I 定 語 從 句

一、 限定性定語從句

1. that即可代表事物也可代表人,which代表事物;它們在從句中作主語或賓語,that在從句中作賓語時??墒÷躁P(guān)系詞,which在從句中作賓語則不能省略。而且,如果which在從句中作“不及物動詞+介詞”的介詞的賓語,注意介詞不要丟掉,而且介詞總是放在關(guān)系代詞which的前邊,但有的則放在它原來的位置

1) The first doll say “mama”was invented in 1830.

[A] that it could
[B] could it
[C] it could
[D] that could

2) A solar day is the length of time the Earth to revolve once around the Sun.

[A] takes
[B] takes it
[C] which takes
[D] he takes

3) The period during when [A] people learned [B] to melt iron is called [C] the [D] Iron Age.

2. which作賓語時,根據(jù)先行詞與定語從句之間的語義關(guān)系,先行詞與which之間的介詞不能丟

4) The second half of his voyage was by far the more dangerous part, he sailed round the treacherous Cape Horn.

[A] where
[B] of which
[C] during which
[D] that

5) To travel from England to Hope Corn had taken him nine months, the sailing time was 226 days. He had done what he wanted to accomplish.

[A] when
[B] which
[C] of which
[D] that

3. 代表物時多用which,但在帶有下列詞的句子中用that而不用which,這些詞包括all, anything, much等,這時的that常被省略(見本節(jié)“四、關(guān)系代詞的省略”)

4. who和whom引導(dǎo)的從句用來修飾人,分別作從句中的主語和賓語,whom作賓語時,要注意它可以作動詞的賓語也可以作介詞的賓語

6) Henry Ford is the person [A] which [B] is most responsible [C] for developing [D] the idea of mass production.

7) Human beings are social [A] animals whom [B] usually prefer not to live in [C] physical or psychological isolation [D] .

5. where是關(guān)系副詞,用來表示地點的定語從句

8) The Everglades is a beautiful region of southern Florida the primitive past mingles with modern life.

[A] there
[B] where
[C] after
[D] in

9) The knee is the joint the thigh bone meets the large bone of the lower leg.

[A] when
[B] where
[C] why
[D] which

10) A metropolitan region [A] is defined as a central [B] city and the territory where [C] surrounds [D] it.

6. when引導(dǎo)定語從句表示時間

[A] as
[B] when
[C] because
[D] that

[D] of

13) Moreover, in the modern age human beings depend so much on machines, he had given men throughout the world new pride.

[A] when
[B] whether
[C] more
[D] ever

[注] 值得一提的是,表示時間“time”一詞的定語從句只用when引導(dǎo),有時不用任何關(guān)系代詞,當(dāng)然也不用that引導(dǎo)

By the time you arrive in London, we will have stayed there for two weeks. / I still remember the first time I met her. / Each time he goes to besiness trip, he brings a lot of living necessities, such as towers, soap, toothbrush etc.

7. whose是關(guān)系代詞,修飾名詞作定語,相當(dāng)于所修飾成分的前置所有格

[A] which
[B] its
[C] that
[D] whose

15) Jackir Mcleans’s recordings have shown that he is one of the few [A] jazz musicians who [B] style of playing [C] has kept pace with the evolution [D] of modern jazz.

16) I don't want to concentrate on anything worrying me.

[A] what is
[B] there is
[C] what
[D] there

二、非限定性定語從句:非限定性定語從句的作用是對所修飾的成分作進一步說明,通常和主句間用逗號隔開,將從句拿掉后其他部分仍可成立

1. which引導(dǎo)的非限定性定語從句來說明前面整個句子的情況或主句的某一部分

2. 在引導(dǎo)限定性定語從句時,that有時相當(dāng)于in which, at which, for which或at which

Attitudes towards daydreaming are changing in much the same way that(in which) attitudes towards night dreaming have changed. 人們對白日做夢的態(tài)度正在改變,這與人們對夜間做夢的看法的變化有非常相似之處。

I like the music for the very reason that(for which) he dislike it. 我出于某種原因喜歡這種音樂,而他恰恰與我相反。

We arrived the day that(on which) they left. 剛好我們到的那天他們走了。

3. 有時as也可用作關(guān)系代詞

4. 在非限定性定語從句中,不能用that,而用who, whom代表人,用which代表事物

17) Ligaments(韌帶), , hold organs of the body in place and fasten bones together.

[A] which are fibrous tissues

19) The first United States citizen to become [A] a professional [B] sculptor was Patience Lovell Wright, which [C] works were executed in wax [D] .

三、定語從句結(jié)構(gòu)錯誤

1. 缺關(guān)系詞

20) The adder is a snake has [A] a relatively [B] stout body, a short tail [C] , and a flat head [D] .

2. 從句中缺成分

21) Traditionally, ethnographers and linguists have paid [A] little attention to cultural interpretations given to [B] silence, or to [C] the types of social contexts in which tends [D] to occur.

四、連接代詞的省略

22) Most crocodiles will eat anything capture and overpower.

[A] can
[B] they can
[C] which can
[D] and

五、例題解析

1) D為正確答案。本句中的主句為“The first doll was invented in 1830”,“that could say ‘mama’”為定語從句,修飾主句中的名詞(主語)“the first doll”。

2) C為正確答案。

3) A錯。during是介詞,它后面的關(guān)系代詞只能用which(指人除外),which在此處指代“the period”,定語從句為“during which people…iron”,修飾主句的主語“the period”。

4) C為正確答案。

5) C為正確答案。

6) B錯。改用who,which只能指物,指人時應(yīng)用who,本句的定語從句修飾the person,關(guān)系代詞who在從句中作主語。本句也可改用that,因為that也可用來指人,它可在從句中作主語或賓語,但which則只能指“物”。

7) B錯。應(yīng)改用who,因為這里所指代的是“human beings”,而且在從句中作主語,而whom只能用來作賓語。

8) B為正確答案??瞻缀笫且粋€定語從句,從句中主謂賓齊全,關(guān)系副詞where指代上面表示地點的名詞region(地方,地區(qū)),相當(dāng)于in which,即in the region,在從句中作地點狀語。

9) B對。空白后為定語從句,從句中的主謂賓語都已齊全,where作從句中的地點狀語,相當(dāng)于in the joint,整個從句修飾“the joint”。

10) C錯。改為which或that。這里是一個定語從句,修飾前面的the territory(區(qū)域),雖然被修飾成分表示一個地點,但若用where代替in the territory在從句中作地點狀語,從句中便沒有了主語,這顯然不對。改用which后,便可由它作從句中的主語,代the territory;從句中的it代上文中的a central city。

11) B為正確答案。

12) C為正確答案。

13) A為正確答案。

14) D為正確答案。這里whose修飾名詞短語“open mouth,” 這時“whose open mouth”一起作介詞“of”的賓語。

15) B錯。who應(yīng)當(dāng)在定語從句中作主語,而從句中已有主語style of playing(演奏風(fēng)格),故應(yīng)將who改為whose,用whose修飾style,指代上文中的人名,相當(dāng)于his。
16) B為正確答案。

17) A對??瞻滋幨莣hich引導(dǎo)的定語從句修飾主句的主語ligaments,which作從句的主語,主句的主語(ligaments)和謂語(hold)被定語從句所隔開。

18) A對。本句是關(guān)系代詞who引導(dǎo)的非限定性定語從句,who指代前面的被修飾成分President Franklin D. Roosevelt并在從句中作主語。

19) C錯。應(yīng)改用whose,修飾從句中的主語works,whose相當(dāng)于his。

20) A錯。本句已有謂語動詞is,而后面又出現(xiàn)動詞has,顯然不合語法,故應(yīng)在snake和has之間加上關(guān)系代詞which或that構(gòu)成定語從句修飾snake,which作從句的主語。

21) D錯。本句“in which”中的which指代“social contexts”,which在從句中已經(jīng)是介詞in的賓語,這樣從句中便沒有了主語,故應(yīng)在which后加代詞it(代silence),即變?yōu)椤癷n which it tends…”,用it作從句的主語,這樣句子才完整。

22) B對。關(guān)系代詞作限定性定語從句中的賓語時可以省略,本句被修飾詞anything后就省去了“that”;C是不對的,首先,C中的which作從句的主語,而從句中的動詞(作謂語)capture and overpower都為及物動詞,可后面沒有賓語,這樣句子便不完整;其次,如果被修飾成分為不定代詞(anything, all等),或修飾成分前有形容詞最高級以及限定性較強的形容詞修飾時(the very,the only,the same,the first,the last,the tallest),應(yīng)使用關(guān)系代詞that,而不用which。

II狀 語 從 句

一、時間狀語從句:主要由when,whenever,after,before,as,(ever)since,once,as soon as,(not)until,while等連詞引導(dǎo)

1) ,Alexander Graham Bell was still a young man.

4) Lucretia Mott’s influence was too significant [A] that she has been credited [B] by some authorities [C] as the originator [D] of feminism is the United States.

5) Dorothy Parker’s satirical [A] verse was quite [B] popular that her books of poetry [C] appeared [D] on bestseller lists.

三、讓步狀語從句: 讓步狀語從句通常由(even)though,although,no matter,even if ,however,whatever等詞引導(dǎo)

四、原因狀語從句: 原因狀語從句可由as,because,since及for引導(dǎo),而托??碱}集中在由“because”引導(dǎo)的從句

8) Nelon is said to be inert does not react easily with other substances.

[A] becaues of it
[B] because it
[C] it is because
[D] is because it

9) Helium is safer than hydrogen it can not explode.

[A] while
[B] though
[C] because

五、條件狀語從句: 表條件的狀語從句主要由if,whether,as long as (只要),provided(只要) (that)等詞引導(dǎo),例如

10) Uniform acceleration occurs the rate of change remains the same over successive equal intervals of time.

13) Nails protect the ends of human fingers and toes protect the toes of most other vertebrates.

[A] claws
[B] as claws
[C] as claws do
[D] so do claws

七、狀語從句中的“主語+be”的省略:狀語從句中的主語和系動詞be常有同時被省略掉的現(xiàn)象,但需有兩個前提條件

(1) 從句主語與主句主語一致,且從句謂語為“be”;

(2) 省略后的結(jié)構(gòu)為“連詞+現(xiàn)在分詞”、“連詞+過去分詞結(jié)構(gòu)”以及“連詞+介詞短語”和“連詞+形容詞(名詞短語) ”結(jié)構(gòu),例

16) When in arctic regions,the Aleuts construct igloos as temporary winter shelters.

[A] travel
[B] to travel
[C] traveling them
[D] traveling

八、例題解析

1) D無論在語法上還是語意上均正確,而若選A和B,則只是兩個句子的無謂羅列,這在英語中是絕對不允許的,而C是一個名詞短語,也不符合要求。

2) B對。本句是由連詞before引導(dǎo)的時間狀語從句,其中的long是副詞,修飾before,“l(fā)ong before”意為“早在…之前”,long before易與before long相混淆,before long相當(dāng)于介詞短語,意思是“不久”。

3) B 對。由于逗號后面是一個完整的句子,則本句空白處成分可能是介詞短語、分詞短語或狀語及狀語從句,在備選答案中,只有B 具備狀語從句的條件。whenever是when的強調(diào)式表示“無論什么時候”。

4) A錯。本句含“so…that”句型,“so”是副詞,它后面可接形容詞或副詞,而“that”后要接表結(jié)果的狀語從句,故應(yīng)將“too”改為“so”。

5) B錯。改為“so”。

6) C對。本句主語為“Hippopotamuses”,謂語是“do not feed”,逗號之間顯然為插入成分,A和B不符合要求,D雖表面上是非限定定語從句修飾前面的成分,但which指主語,馬上又接主語they,成了“雙主語”,故應(yīng)排除。C是由連詞although(盡管) 引導(dǎo)的讓步狀語從句作插入語,完全符合條件,故應(yīng)選C。

7) B對。逗號后為一完整的句子,逗號前又出現(xiàn)了謂語,那么空白處一定缺起引導(dǎo)從句作用的連詞和從句主語,B 完全符合條件,though的用法和although基本相同,意思也相同。C 好像是“that”引導(dǎo)的主語從句,可后面接的并不是謂語,而是一個句子,故C 也不對。D 貌似“it is…that”強調(diào)句,但句中缺that,且語法語意混亂。

8) B對。A不對,因為“because of ”(因為) 是成語介詞,后面不可接句子,而C和D均不合語法,只有B正確,“it”指代“neon”。

9) C對。本題中的四個選項都是連接詞,即都可以引導(dǎo)后面的從句,從語法來說,它們都正確,但從語意及邏輯上看,顯然以“[C] because”(表“原因”) 切合題意。

10) B對。本句缺能引導(dǎo)一個從句的連接詞,只有B符合條件。

11) C對。whether作為連詞,只能放在從句句首,故B 和D 都不符合語法。雖然A中的whether放置于句首,但A 不是一個句子,因此只有C 中的whether才引導(dǎo)了一個狀語從句,“whether…or not”在此處表示“無論…”。

12) A對?!皐here”引導(dǎo)的是地點狀語從句,表示“在大西洋通過赤道的地方”。

13) B對?!癮s claws protect…”表示“正如爪或鉗保護…一樣”,as引導(dǎo)的是方式狀語從句。A 明顯不對。C 多“do”,D 好像是“so”引導(dǎo)的倒裝句,但“so”不僅無所指代,因為后面不缺任何成分,而且在用“so”倒裝句時,“so”前面通常有逗號,并且是“so+助動詞(或情態(tài)動詞等) +主語”結(jié)構(gòu)。

14) A對。從句部分說完整為“When they (glasses) are well fitted”,其中的“they are”被省略掉了。D 中的“If well fitted”本來也正確,但后面多“when”。

15) A對。although后省略了“they (bones) are”,apparently(明顯地)是副詞,修飾后面的形容詞rigid。D 中的are和they順序有誤,否則也同樣正確。

16) D對。本句為“連詞+現(xiàn)在分詞”結(jié)構(gòu)。

III 名 詞 從 句

名詞從句即語法功能相當(dāng)于名詞或名詞短語的從句,包括主語從句、賓語從句、表語從句和同位語從句。

一、主語從句

1. 由關(guān)系代詞what、代詞whatever或whoever代詞引起的主語從句

1) concerned with is the measurement of angles and their relationships to each other.

[A] Trigonometry is
[B] That trigonometry is
[C] What is trigonometry
[D] What trigonometry is

但what有時在從句中也作定語,如:What little information he collected from it is not enough for us. 他從計算機上收集的那一點點信息不夠我們用。

2. 由連詞that引起的主語從句,謂語一般是系表結(jié)構(gòu),在大多數(shù)情況下,that從句由it做形式主語

2) has not attained a state of complete coherence is true.

[A] Cultural anthropology
[B] That cultural anthropology
[C] Anthropology that is cultural
[D] Since cultural anthropology

3) for granted that any new lawn will need to be fertilized.

[C] Taking
[D] It should be taken

4) Today [A] it is generally recognized as [B] the primary function of the Federal Reserve System is to foster the flow of credit and money [C] that will eventually facilitate [D] a balance in international payments.

3. 由連接代詞、連接副詞及whether(是否) 引起的主語從句

5) some mammals came to live in the sea is not known.

[A] That
[B] Since
[C] Although
[D] How

6) made the first United States flag is widely believed.

[A] When Besty Ross
[B] That Besty Ross
[C] Besty Ross
[D] Whether Besty Ross

4. 由于主語過長,更多的情況下用it代替主語從句,而把that引導(dǎo)的從句放到后邊

It is a fact accepted by economists that technological…scarcities.(“it”充當(dāng)邏輯主語。)

二、賓語從句

1. 由連詞that、疑問代詞或副詞(如how, why和where等)引出的賓語從句

7) Almost all economists agree by trading with one another.

[A] nations that are gained
[B] nations they gain
[C] gaining nations
[D] that nations gain

8) Like a magazine,a newspaper has a contents guide that indicates located.

[A] where each feature is
[B] each of the feature is
[C] each feature where it is
[D] where is each feature

2 介詞后的賓語,其賓語可以是名詞或代詞,也可以是個句子,即賓語從句,也可以由“what”來引導(dǎo)

9) The chief foods eaten in any country depends largely on best in its climate and soil.

[A] it grows
[B] what grows
[C] does it grow
[D] what does it grow

10) When Europeans originally arrived in El Paso,Texas,the area was inhabited by the Manso and Suma peoples.

[A] what is now
[B] now
[C] which now is
[D] now is

三、表語從句

11) A logarithm(對數(shù)) is in algebra as an exponent.

[A] known that
[C] what is known
[B] known what it is
[D] what it is known

四、同位語從句:由兩個或兩個以上同一層次語言單位組成的結(jié)構(gòu),其中前項與后項所指相同,句法功能也相同,這種結(jié)構(gòu)叫同位結(jié)構(gòu)。名詞詞組,反身代詞,不定代詞或指示代詞、ING分詞、不定式和從句都可作同位語。用來作同位語的從句叫同位語從句。同位語從句主要由that引導(dǎo),這時that從句表示它所修飾詞的實際內(nèi)容

1 名詞短語作主語的后置同位語

12) George H.Gallup, specialized in opinion polls and business surveys.

[A] whose statistician
[C] a statistician who

3 作賓語或表語的后置同位語

[C] is that the distance

[A] new dance,the twist
[B] twist,was the new dance
[C] twist,the new dance that
[D] new dance is the twist

五、例題解析

1) D對。句中已出現(xiàn)了謂語動詞“is”,這就決定了“is”前面為其主語,如主語中再有動詞出現(xiàn),便成了主語從句。A 不對。因為連續(xù)出現(xiàn)了兩個動詞“is”,且其間又無連接詞;B好像是“that”引導(dǎo)的主語從句(下面將提到) ,但由于介詞“with”要求帶賓語,而B 選項本身又無法解決這個問題(“that”引導(dǎo)的主語從句中,“that”為連詞,不可能去充當(dāng)“with”的賓語) ,故B也應(yīng)排除;C句的語序有誤,因本句并非倒裝句(句末為句號),因此沒必要倒裝;只有D為正確答案。“what”為代詞,相當(dāng)于“the thing which”,這樣“what”本身便可充當(dāng)“with”的賓語。本句的漢語意思為“三角學(xué)所涉及的(對象) 是角的測量及角之間的關(guān)系”。因此,凡“what”帶的從句中,“what”本身一定要充當(dāng)從句中的成分,或賓語(含介詞賓語) ,或主語。

2) B對。本句有兩個動詞(“has”和“is”),且中間并無等立連詞分開,顯然本句為一個名詞從句作主語的句型,符合此條件的只有B,其中句首的“that”與“what”引導(dǎo)的主語從句的區(qū)別在于:“that”在句中不充當(dāng)任何成分。本句更多的情況下是說成:“It is true that cultural…coherence.”這樣就由“it”充當(dāng)邏輯主語,而真正的主語“that從句”放在了后面。

3) D為正確答案。句首的“it”為邏輯主語,指代后面的“that從句”,本句亦可說成“That any new…fertilized should be taken for granted”。

4) B錯。改為“that”,理由見上例。

5) D對。本句漢語意思是“某些哺乳類動物是如何到海中生存的仍是一個迷?!蹦敲碅 為什么不對呢?為什么不可理解為是“that”引導(dǎo)的主語從句呢?“that從句”作主語時是陳述性的句子,即為一個事實,因此句子的謂語也應(yīng)與其呼應(yīng),即肯定性的論述;而由疑問代詞、副詞及whether引導(dǎo)的主語從句都為疑問性的句子,即不是肯定的結(jié)論,因此其謂語也應(yīng)當(dāng)是否定的或含疑問性質(zhì)的論述。本句中的謂語為“is not known”(大家不知道) 即屬于否定的和含疑問性質(zhì)的論述,故應(yīng)選D。

6) B為正確答案。本句的謂語“is widely believed”(被廣泛地認可) 為肯定性的論述,因此A和D選項不對。

7) D對?!癮gree”(同意) 可以后面接“that”引導(dǎo)的賓語從句,但它不可直接跟名詞作其賓語,如要接名詞,需在名詞前加介詞“upon”、“on”或“with”。

8) A對?!癷ndicate”(顯示) 為及物動詞,它后面接了一個以“where”引導(dǎo)的賓語從句。由于本句為陳述句,故D 答案不對。

9) B對?!皐hat grows…”作介詞“on”的賓語,其中“what”作從句的主語,相當(dāng)于the thing which。

10) A對。

11) C對。本句系動詞 “is”后需接表語,而C為由“what”引導(dǎo)的從句,可以充當(dāng)其表語,故C 為正確答案。B 不對。因為“known”無論是形容詞還是過去分詞都不可再接“what”從句;D 中的“it”多余,因為它占據(jù)了從句中主語的位置,這樣,從句中既不缺主語,也不缺賓語和表語,于是代詞“what”便無所指,故只有C 為唯一正確答案。

12) B對。空白處成分系進一步解釋說明句子的主語,位于主語和謂語之間,且前后有逗號隔開,將同位語去掉原句仍完整,其功能相當(dāng)于一個非限定性定語從句,即“who was a statistician”。

13) D對。理由同上例。

14) A對?!皌hyme”是一種植物名稱,由于該詞不常見,故后面用同位語進行說明。需要指出的是,B選項里如在“garden”前加上冠詞“a”(因為herb為可數(shù)名詞) ,那么B也同樣正確。

15) C為正確答案?!皌he term”(術(shù)語) 與其后“modeling”(用于雕刻的一種術(shù)語) 同位,即二者指的是同一事物。

16) A對?!皊on”前省略了冠詞“a”,因為表示身份時,不定冠詞可省略,空白處成分與后面的人名同指一人。

17) D對。本句意思為“奧林匹克馬拉松比賽長度為26英里385碼,即大約從馬拉松(地名) 到雅典的距離”,逗號后面的成分是作為本句表示長度的表語同位語形式出現(xiàn)的,其作用是進一步解釋前面的成分。

18) A對?!皌he twist”(搖擺舞) 即是“a new dance”的同位語。全句意為“1961年,…將一種新式的舞,即搖擺舞,介紹給了紐約的搖滾舞迷們”。

IV THERE BE 句型

一、there be結(jié)構(gòu)

英語表示“某地或某時存在什么事物”。在這種結(jié)構(gòu)中,there是個引導(dǎo)詞(由副詞there變來),本身沒有意義,所以常弱讀為[], 因be是謂語,后邊跟名詞或相當(dāng)于名詞的短語,作主語;這時be的形式要與其后邊的主語在數(shù)上保持一致;最后為要點或時間狀語。如

There are several books on the shelf. 書架上有幾本書。/

There was a severe drought in the North in 1995. 1995年北方大旱。

二、 there be結(jié)構(gòu)的否定式或疑問式

是在there be后加not或?qū)e放到there之前。如:There is not …; There are not…; Is there …? Are there…?

三、 there be結(jié)構(gòu)的各種時態(tài)

there be中的“be”除了有is和are的形式以外,還有其時態(tài):there was(not)…; there were(not)…;there will be…;there may be…;there might be…; there has been…; there have been …。

四、 there 與非謂語動語連用

這時的引導(dǎo)詞there似乎變成了主語,如

1 . 接不定式:You wouldn't want there to be another war, would you? 你不會愿意再有一場戰(zhàn)爭,是嗎? / Would you like there to be a meeting to discuss the problem? 你們要開個會討論一下這個問題嗎? / It was too late for there to be any subways. 太晚了,不會有地鐵了(for 后接動詞不定式)。

2 . 接ING形式: Have you ever thought of there being so many workunits for you to choose on the talents' meeting? 你是否曾想到過在人才交流會上會有許多的工作單位供你選擇嗎?(of后接ING形式) / There being something to do, we will stay here to finish it. 這兒還有活,我們得干完。

五、 there be結(jié)構(gòu)用在定語從句中

Such books as there were on the self interested us. 我們對書架上的這些書感興趣。 /

That's all there is to it. 如此而已。 /

Have you noticed anything (that) there is happening in the company. 你注意到公司正在發(fā)生什么變化嗎?

V 溶 合 句

英語一句話的結(jié)束用句號,即圓點。在一句話中分句與分句之間要么用疑問代詞、疑問副詞或連接詞引導(dǎo)從句,形成主從結(jié)構(gòu),要么用并列連詞或分號形成并列分句關(guān)系。但逗號不能起到連詞來連接并列句的作用。用逗號連接的兩個分句叫溶合句,這在英語中是不符合語法的。在挑錯題中我們應(yīng)當(dāng)注意這種不符合語法的句子。
