一、定语从句

1.I will never forget the fire ______________ happened in Shanghai last year.

A.when B.where

C.what D.which

【答案】D

【解析】

【分析】

考点:考查定语从句。

【详解】

试题分析:句意:我将永远不会忘记去年上海发生的火灾。先行词the fire是物,故其定语从句要用which引导。what不引导定语从句;when先行词是时间;where先行词是地点;根据题意,故选D。

2.— What are you doing, Tim?

— I am listening to the song Long Live _______ makes me feel excited.

A.which B.who C./

【答案】A

【解析】

试题分析:句意:-- Tim,你在做什么?--我在听歌曲Long Live,它使我感觉很兴奋。这里先行词是the song Long Live,是物;定语从句缺少的是句子的主语,关系词不能省略。which指物,故选A。

考点:考查定语从句的用法。

3.—Have you ever heard of Langlang?

—Sure. He is one of ______ pianists ______ I have even seen.

A.good; that B.much better; who

C.the best; which D.the best; that

【答案】D

【解析】

【分析】

【详解】

句意:——你有没有听说朗朗?——当然听说了。他是我见过的最好的钢琴家之一。Good

好的,better更好的;best最好的。形容词的比较级前可用much修饰,表示程度;形容词的最高级前通常要加定冠词。one of……之一,其后面的中心名词用复数形式,该名词前的形容词用最高级形式。先行词pianists在宾语从句中作宾语,他的前面有最高级修饰,该用关系代词that代替。所以选D。

4.Most students like the teachers understand them well.

A.which B.who C.where D.when

【答案】B

【解析】

试题分析:句意:绝大多数的学生都喜欢能够很好理解他们的老师。分析:考查定语从句的用法,先行词是the teacher,先行词在从句中作主语,因此引导词用who.故选 B

考点:考查定语从句的用法。

5. My grandparents like stories ________ have happy endings.

A.they B.who

C.which D./

【答案】C

【解析】

【详解】

句意:我爷爷奶奶喜欢有快乐结局的故事。考查定语从句。先行词stories(故事)表示物,需用关系代词that或which,引导词同时做从句的主语,根据句意结构,故选C。

6.The book ___ I read last night was fantastic.

A.that B.what C.whose D.who

【答案】A

【解析】

【详解】

句意:我昨晚读的那本书真是太棒了。此句考查定语从句的关系词。A. that先行词是人或物,在从句中作主语或宾语;B. what不能引导定语从句;C. whose先行词是人或物,在从句中作定语;D. who先行词是人,在从句中作主语或宾语。本句的先行词book指物,用that来引导,故答案为A。

【点睛】

在定语从句中,关系代词所代替的先行词是人或物的名词或代词,并在句中充当主语、宾语、定语等成分。关系代词在定语从句中作主语时,从句谓语动词的人称和数要和先行词保持一致。

1) who, whom, that这些词代替的先行词是人的名词或代词,在从句中所起作用如下:

Is he the man who/that wants to see you? 他就是想见你的人吗?(who/that在从句中作主语)

He is the man whom/ that I saw yesterday. 他就是我昨天见的那个人。(whom/that在从句中

作宾语)

2) whose 用来指人或物,(只用作定语, 若指物,它还可以同of which互换),例如:They rushed over to help the man whose car had broken down. 那人车坏了,大家都跑过去帮忙。

3) which, that 它们所代替的先行词是事物的名词或代词,在从句中可作主语、宾语等。4)关系副词可代替的先行词是时间、地点或理由的名词,在从句中作状语。关系副词when, where, why的含义相当于"介词+ which"结构,因此常常和"介词+ which"结构交替使用,例如:Beijing is the place where (in which) I was born. 北京是我的出生地。

7.—What kind of movies do you like?

—I prefer movies _____give me something to think about.

A.which B.who C.what D.when

【答案】A

【解析】

【详解】

句意:——你喜欢什么种类的电影?——我更喜欢给我一些思考的东西的电影。

A. which关系词,先行词是物;

B. who关系词,先行词指人;

C. what不能引导定语从句;

D. when关系副词,在定语从句中做状语。先行词是movies指物,关系词用which。根据题意,故选A。

8.That was his first invention. It was a machine ________ clothes.

A.that used to wash B.which was used to washing

C.which got used to washing D.that was used to wash

【答案】D

【解析】

【详解】

句意:那是他的第一个发明。那是一台用来洗衣服的机器。本题考查的是be used to do sth. “被用于做某事”的用法,而不是be/get used to doing sth. “习惯于做某事”的用法,排除

B/C;再由That was his first invention.可知,本题是过去时,因此在that引导的定语从句中,应该用一般过去时的被动句。was used to wash被用来洗衣服,语境是:那是一台被用来洗衣服的机器。故选D。

9.Being blind is something _________ most people can’t imagine.

A.who B.what C.that D.whom

【答案】C

【解析】

先行词是something,关系代词用that。

【考点】定语从句引导词。

10.The number of people_____were killed in the accident_____been announced yet. A.that; hav en′t B.who; hasn′t C.which; hasn′t D.who; haven′t

【答案】B

【解析】

试题分析:句意:在事故中死亡的人的数量还没有被公布。第一空后_____were killed in the accident是定语从句,先行词是people,指人的所以可以用that或who,第二空缺少的是谓语动词,句子的主语是The number 单数,所以谓语动词也用单数形式,故选B。

考点:考查定语从句及主谓一致的用法。

11.-----Do you know the man ________ is reading the book over there?

--------- Yes, he is Mr. Green, our P.E. teacher.

A.which B.what C.whom D.who

【答案】D

【解析】

who代指the man引导定语从句。整句理解:你认识那边读书的那个男士吗?是的。他是我们的体育老师,Mr Green.所以选D.

12.When we speak of culture, we mean a way of life_________ a group of people have in common.

A.what B.who C.where D.that

【答案】D

【解析】

【详解】

句意:当我们说起文化的时候,我们指的是一群人共同拥有的生活方式。考查定语从句的引导词。根据句意:当我们说起文化的时候,我们指的是一群人共同拥有的生活方式。逗号后面的句中是含有定语从句的复合句,先行词是 life,表示“物”,用引导词 that,在从句中做宾语。what 不能引导定语从句。先行词是“人”,引导词常用 who。where 在定语从句中做地点状语。故选D。

【点睛】

引导定语从句的关联词包括关系代词和关系副词。关系代词有that, which, whose, who, whom, as;关系副词有when, where, why。关系代词和关系副词在定语从句中都充当一定的句法成份。关系代词在从句中充当动词的宾语时一般可以省略。

13.The last place _______ we visited was Chaoshan Custom Museum.

A.where B.that C.when D.why

【答案】B

【解析】

句意:我们参观的最后一个地方是潮汕风俗博物馆。根据句子结构可知,这里考查的是定语从句,where关系副词,指地点;that关系代词,先行词为物;when关系副词,指时

间;why关系副词,指原因。定语从句中visited后缺少宾语,故应填关系代词,选B。

14.She is talking about the school and teachers ______ we visited last month.

A.who B.which C.where D.that

【答案】D

【解析】

句意:她正在谈论关于我们上个月参观的那个学校和那里的老师。who引导定语从句,修饰人,作主语或宾语;which引导定语从句,修饰事物,作主语或宾语;where引导定语从句,修饰地点名词,作状语;that引导定语从句,修饰人或事物,作主语或宾语。根据the school and teachers可知此处既修饰人,又修饰事物,故用that引导定语从句,故选D。

15.I like listening to music______ can touch the heart of people.

A.that B.who C.where D.what

【答案】A

【解析】

【详解】

句意:我喜欢听能触动人心的音乐。考查定语从句引导词。what不引导定语从句,可排除。that可指人指物;who指人;where指地点。本句先行词music是物,引导词做从句的主语,需用that引导;根据句意语境,可知选A。

16.一Which song do you like better.Maria?

一I prefer the song Manual of Youth ______ is sung by TFBOYS.

A.who B.whom C.which D./

【答案】C

【解析】

【详解】

C 考查定语从句的引导词。句意:—Maria,你更喜欢哪首歌?—我喜欢TFBOYS唱的《青春修炼手册》。分析句子结构,本句中的 is sung by TFBOYS在复合句中作定语从句,其中先行词 the song Manual of Youth 指物,且在定语从句中作逻辑主语,所以关系代词用which.故选C.

【点睛】

完成定于从句的关键是分析先行词指人还是指物,以及其在定语从句中做什么句子成分.

17.– Do you like the weekly talk show The Readers on CCTV?

–Sure. It’s a great TV program can develop the habit of reading.

A.who B.that C.what D.whose

【答案】B

【解析】

【详解】

句意:——你喜欢中央电视台每周一次的节目《朗读者》吗?——当然了,这是一个很棒的节目,能培养阅读的习惯。

根据句子结构可知,这里考查定语从句,who是关系代词,先行词为人,在从句中作主语或宾语;that先行词人或物都可以,在从句中作主语或宾语;what不能引导定语从句,先排除;whose…的,先行词可以是人或物。这个定语从句的先行词是program,故排除A;D 选项意思不合适。故应选B。

18.Fewer and fewer people spend time reading. There were only 49% of adults in the US

________ visited a public library last year.

A.who B.where C.when D.which

【答案】A

【解析】

【答案】D

【解析】

句意:——你认识那个其父亲来自日本的男孩吗?——是的,他的名字叫迈克。考查定语从句。先行词the boy是人,不可用指物的which,可排除C。who和whom虽指人,但用于人称,空格后有名词father,所以空格需填表物主的whose。根据句意结构,可知选D。

21.Is this factory _______ you visited the other day?

A.in which B.which C.where D.the one

【答案】D

【解析】

试题分析:句意:这个工厂是你前几天参观的那个工厂吗?我们可以先把这个句子变成陈

中考英语单选易错题

大家知道,现在的中考英语试题总体不难,只要不放弃英语学习的学生都可以考及格以上,但欲考接近满分却并非易事。因为为了适当拉开学生距离,命题老师往往也会出一两个所谓的压轴题,以把那些真正的英语尖子生选拔出来。有时候我们学生与重点高中失之交臂,就是失分在下面我精选的难题上。 ( ) 1. ________ it is today! A. What fine weather B. What a fine weather C. How a fine weather D. How fine a weather 解析:选A. 此题容易误选B. weather是不可数名词,前面不能有不定冠词。英语中经常考查的不可数名词有work, news, adivice, information等。 ( ) 2. Which is the way to the __________? A. shoe factory B. shoes factory C. shoe’s factory D. shoes’ factory 解析:选A. 此题极易误选B, C, D. 英语中名词单数可以修饰名词,如:an apple tree →two apple trees. 但注意a man teacher→two men teachers。 ( ) 3. This class ________ now. Miss Gao teaches them。 A. are studying B. is studying C. be studying D. studying 解析:选A. 此题容易误选B. class, family, team等单词如果表示整体谓语就用单数,表示个体就用复数,从语境及其后面的代词them可以看出,class表示个体,故选择A。( ) 4. We will have a _________ holiday after the exam。 A. two month B. two-month C. two month’s D. two-months 解析:选择B 此题容易误选C, D. 在英语中数词中间用连字符号加名词单数,构成符合名词,在句中只能作定语,如果选择C, 需要把逗号放s后面。 ( ) 5. There is no enough ________ on the corner to put the table。 A. place B. room C. floor D. ground 解析:选B. 此题最容易误选A.。room在句中是空间而非房间。句意:角落里没有摆桌子的空间了。 ( ) 6. We can have _____ blue sky if we create _____ less polluted world。(苏州2010) A. a; a B. a; the C. the; a D. the; the 解析:选A. 此题容易误选C, D. 根据句意:如果我们创造一个没有污染的世界,那么我们就用一个蓝色的天空。 ( ) 7. —Are you ______ American or English? —English.. We are working in Wuhu. (芜湖10) A. a B. \ C. the D. an 解析:选B 此题容易误选D. 句中American是形容词而非名词,如果句中改为Are you __________ or an English man? 就选择D。 ( ) 8. You like playing basketball, and he likes running, _______? A. don’t you B. doesn’t he C. do you D. does he 解析:选择B. 此题容易误选A. 其实不是对前面的句中进行反问,而是对he likes running 进行反问。 ( ) 9. —Why not take ____umbrella with the sign “Made in China”?It is _____ useful umbrella? —What _______ good advice it is! A. an; an; a B. an; a; \ C. a; an; a D. \; an; a 解析:选B. 大多数学生容易做错此题。记住an用在元音音素前而不是元音字母前,记住了这一点就知道了an umbrella 和a useful umbrella. 在最后一句中advice是不可数名词,前面不能接不定冠词。故选择B ( ) 10. — When shall we meet again next week?

超全2021年中考英语选择易错题集锦和练习含答案

2021年中考英语选择易错题集锦 1. It is _______ outside. Let’s put on our raincoats and go out, Tom. A. cold B. hot C. sunny D. rainy 【解析】此题易误为A。因为这里有个put on短语,如果不注意raincoats这个词那就很可能草率地选择A。raincoats是“雨衣”的意思,而不是一般的衣服,那么不是因为外面“冷”,而是因为“下雨”才穿“雨衣”。正确答案为D。 2. —_______ do you _______ about spring? —The flowers and the green trees. A. How, like B. How, think C. What, think D. What, like 【解析】此题陷阱选项为A或B或C。这是由于忽略语境造成的。由答语The flowers and the green trees. 可知,所问的是“你喜欢春天的什么?”而不是“你觉得春天怎么样?”。正确答案为D。 3. —What’s your sister like? —_______. A. She is a worker B. She likes pears C. She is very thin D. She is like her father 【解析】此题陷阱选项为B或D。有很多考生一看题干中的like一词就会想当然地选择B或D。其实,问句的意思是“你姐姐长得怎么样?”因此,正确答案为C。What’s …like? 这个句型常常用来询问某人的长相或某事的情况(包括天气情况)。
