定语从句练习题含答案

定语从句练习题附答案解析1．Success falls to those ________ hold their dreams and put their hearts into them. A．which B．whom C．what D．who【答案】D【解析】【详解】句意：成功属于那些坚守他们的梦想，并全身心投入其中的那些人。

考查定语从句。

which定语从句中作主语或宾语，指代物；whom定语从句中作宾语，指代人；what用于名词性从句；who定语从句中作主语或宾语，指代人。

“hold their dreams and put their hearts into them”是定语从句，从句缺主语，先行词是“those”，指的是人。

用关系代词who作从句的主语。

故选D。

2．I still remember the college and the teachers ______________ I visited in London years ago.A．which B．who C．that【答案】C【解析】【详解】句意：我仍然记得我几年前在伦敦参观过的学院和老师。

考查定语从句。

which哪一个，关系代词，先行词指物，在从句中做主语和宾语；who谁，关系代词，先行词指人，在从句中做主语；that关系代词，先行词指人或者物，在从句中做主语或宾语；根据句意理解可知，句中先行词是the college and the teachers，既包括人又包括物，所以这里应该用that，故选C。

【点睛】定语从句重点考查关系词的应用。

在定语从句中关系词用哪个，主要取决于先行词，先行词指人，关系词用who/ whom/ that，指人做主语用who/ that，做宾语用whom，先行词指物，关系词用which/ that，而有些情况只能用that，这些情况有：①先行词为不定代词all, anything, nothing, …；②先行词有最高级修饰，有序数词修饰；③先行词有only, very, any等词修饰；④先行词既能表示人又表示物，本题就是先行词既指人有指物，所以用that。

考查定语从句。

作为定语从句的关系词，where先行词表示地点，在句中作地点状语。

which先行词是物，在从句中做主语或宾语；that先行词是人或物，在从句中做主语或宾语、本题定语从句的先行词是物，主句中有形容词最高级，只用that，不能用which。

故选C。

2．—I planted some flowers in the yard, but they haven't come out yet.—Be patient, please. All things come to those ________ wait.A．whom B．what C．who D．which【答案】C【解析】【详解】句意：——我在院子里种了一些花，但还没有长出来。

——请耐心等待。

耐心等待，万事皆成。

考查定语从句。

what不是关系词，可排除。

whom和whom都用于先行词是人时，但whom不可做主语；which用于先行词是物时。

本句先行词those指代人，在从句中做主语，根据句意结构，可知需用who，故选C。

3．The person _________ I just talked is Mr. Lin.A．who B．to who C．that D．to whom【答案】D【解析】【详解】句意：刚才和我谈话的那个人是林先生。

考查介词+关系代词。

who代指人；to who表述错误（介词后接宾格）；that代指人或物；to whom介词+关系代词；根据“talk to sb”表示为“和某人交谈”，分析句子结构，先行词是“The person”，to后接关系代词whom，故选D。

定语从句练习题附答案解析1．I really like the family photo ________ we took on my grandpa’s 80th birthday. A．who B．that C．what D．whose【答案】B【解析】【详解】句意：我真的很喜欢爷爷80岁生日时拍的全家福。

本题考查定语从句。

A. who 指代人；B. that既可以指人又可以指物；C. what不能引导定语从句；D. whose 指代某人/物的。

根据题干可知本句中的先行词是photo，指物，所以B选项that符合题意，故答案选B。

2．— Jim is so busy with his work on the computer now.— Yes, he is searching the information __________ he needs for his article. A．that B．whether C．what D．who【答案】A【解析】【详解】句意：——吉姆现在在电脑上忙着工作。

——是的，他正在搜索他文章所需的信息。

考查定语从句。

根据英语语法，whether和what不可以引导定语从句，B、C选项可排除。

根据句子结构，定语从句的先行词information指物，关系代词who 指人，D选项可排除，故选A。

【点睛】关系代词that既可以指人也可以指物，在从句中作主语、宾语或表语；关系代词who指人，在定语从句中做主语，作宾语时应用whom。

此处先行词information指物，且关系代词在定语从句中作宾语，故应用关系代词that。

3．The research he had devoted himself ________ a perfect success.A．to proved B．proved C．to prove D．to proving【答案】A【解析】【详解】句意：他致力于的研究证明是相当成功的。

英语定语从句练习题20篇及解析一、定语从句1．Running man is a very relaxing TV program_______is hot among the young people.A．what【答案】B【解析】【分析】B．XXX【点评】定语从句要注意先行词是人还是物，从而选出合适的关系代词．【详解】试题分析：定语从句中先行词为物，关系代词用that或which．what不引导定语从句，who/whom的先行词是人；根据 a very relaxing TV program可知，先行词是物，故选B．2．—What kind of movies do you prefer?—I prefer the movies _________me something to think about.A．which give【答案】A【剖析】句意：——你喜欢什么类型的电影？——我更喜欢那些让我思考的电影。

此句的先行词是movies，引导定语从句的关联词用that或which，排除C,D；定语从句的主语that或which指代movies，动词不能用三单形式，故答案为A。

B．that XXX gives3．The We Chat is an invention can help people talk to friends, share photos, XXX.A．which【答案】A【剖析】试题分析：句意：微信是可以帮助人们和朋友自由地聊天，分享照片，想法和感觉。

考点：考查定语从句的用法。

B．XXX4．This is the dictionary ________ XXX.A．which【答案】A【解析】【详解】B．XXX句意：这是那本母亲给我作为华诞礼品的字典。

定语从句练习题附答案解析1．Yuan Longping is a scientist ________ is famous for the development of rice. A．that B．whomC．what D．which【答案】A【解析】【详解】句意：袁龙平是一位以水稻的发展而闻名的科学家。

这里是定语从句，先行词是a scientist是指人，这里关系词用that或who；如果先行词是物，关系词用that或which。

Whom先行词是人，在定语从句中做宾语；what不能引导定语从句；根据题意，故选A。

【点睛】which 与 that 在定语从句中被称为：关系代词which 引导定语从句时,先行词是物,在从句中可做主语、宾语、表语that 引导定语从句时,先行词既可以是人,也可以是物,在从句中也可做主语、宾语、表语关于which和that的常考点：一、在限制性定语从句中,只能用that不能用which的情况：1）当先行词是指物的不定代词例：Do you have anything that you want to say for yourself?2）当先行词前面有下列词修饰时：the only,the very,just,any,every,some等例：This is the very busy that I’m waiting for.3）当先行词是形容词的最高级或先行词的前面有形容词最高级修饰时例子：This is the best that has been used against pollution.4）当先行词是序数词或前面有序数词修饰时例：The train is the last that will go to Suzhou.5）当先行词既有人,又有物例：Do you know the things and persons that they are talking about?6）当主句的主语是疑问词 who 或 which 时例：which is the bike that you lost?Who is the boy that won the gold medal?7）主句是there be句型且关系词在从句中作主语时例：there is a seat in the corner that is still available.2．— Do you still remember the days _______ we spent together, James?—Of course.

考查定语从句的引导词。

此句使用了定语从句，先行词“Lee Kuan Yew”表示人，应用引导词that或who引导定语从句，而此句为非限制性定语从句，that不能引导非限制性定语从句，who可以，故选B。

2．In our class, Frank is the only person _____ is good at clay art.A．which B．that C．whom【答案】B【解析】【详解】句意：在我们班，弗兰克是唯一擅长泥塑艺术的人。

考查定语从句。

which先行词是物，在从句中作主语或宾语；that先行词是人或物，在从句中作主语或宾语；whom先行词是人，在从句中作宾语。

题干中先行词person指人，且在句中作主语，其前有the only修饰，关系词只能用that。

故选B。

3．He was also a famous philosopher ________ wise sayings have influenced many people in different countries.A．whose B．who C．whom D．that【答案】A【解析】【详解】句意：他也是一位著名的哲学家，他的至理名言影响了许多不同国家的人。

考查定语从句的关系词。

whose定语从句关系词，在句中作定语；who定语从句关系词，在句中作主语；whom 定语从句关系词，在句中作宾语；that定语从句关系词，在句中作主语或宾语；先行词是philosopher哲学家，是指人，和从句的主语 sayings 是所属关系，在定语从句中作定语，用whose。

定语从句练习题附答案解析1．—Do you know the boy ________is talking to Mr Zhang?—Yes. He is our monitor.A．which B．who C．whose D．whom【答案】B【解析】【详解】句意：——你认识正在和张先生说话的那个男孩吗？——是的。

他是我们的班长。

考查定语从句。

which引导定语从句先行词指物，在从句中作主语、宾语；who 引导定语从句先行词指人，在从句中作主语；whose引导定语从句先行词指人或物，在从句中作定语；whom引导定语从句先行词指人，在从句中作宾语。

由“Do you know the boy…is talking to Mr Zhang”可知，从句中缺少主语，且先行词boy指人，故应用who引导定语从句。

故选B。

2．I was so angry at all________he was doing________I walked out. A．that…that B．which…that C．who…which【答案】A【解析】【详解】句意：对于他正在做的一切我表示很生气，以至于我走了。

考查定语从句以及状语从句。

第一空根据he was doing，说明先行词all在定语从句中作宾语，用that或 which，因前面是all不定代词，故只能用that；第二空根据so…that如此……以至于，结果状语从句。

综上，故选A。

【点睛】that这个引导词在定语从句中是既可以指人也可以指物，which在定语从句中一般经常指物。

当先行词是all, something, nothing等不定代词时候，引导词要用that，不能用which。

3．—Is this the new dictionary ________ you got yesterday?—Yes. Now it’s very convenient for me to look up words.A．that B．why C．what D．when【答案】A【解析】【详解】句意：——这是你昨天买的新的字典吗？——是的，现在对于我来说记单词是非常方便的。

定语从句练习题附答案解析1．I am the person______ wrote to you last week．A．whom B．whoC．which D．he【答案】B【解析】【详解】句意：我是上周给你写信的那个人。

A. whom关系代词，指人，在从句中作宾语；B. who关系代词，指人，在从句中作主语或宾语；C. which关系代词，指物，在从句中作主语或宾语；D. he 他，人称代词，不能起连接的作用，故排除D。

此句先行词person是人，从______ wrote to you last week可知，从句缺主语，故关系代词用who。

故选B。

2．The novel________he read to his brother yesterday________be Dickens’. It was written by another famous writer.A．that; can B．which; must C．/; can’t【答案】C【解析】【详解】句意：昨天他给他弟弟读的小说不可能是迪更斯的，它是另一个著名作家写的。

考查定语从句和情态动词。

根据句子结构可知是定语从句，先行词是物时，引导词用that或which，当引导词在从句中做宾语时，可以省略；It was written by another famous writer. 它是另一个著名作家写的，可知，不可能是迪更斯的；can能，会；must必须，一定；can’t不能，不可能；故选C。

【点睛】can能，会can’t不能，不可能，通常用于否定句的推测；should应该，shouldn’t不应该；may可以，可能，通常用于肯定句的推测，may not可能不；must必须，一定mustn’t必须不能。

情态动词后接动词原形，变疑问句时把情态动词提前，变否定句在情态动词后加not 。

must引导的一般疑问句，表示必须时，否定回答用needn’t；may引导的一般疑问句，否定回答用can’t3．—Have you watched the TV play “In the name of people”（人民的名义）?—Yes. It’s the most popular play ______ shows our Party’s trying to struggle against corruption（反对腐败）.A．where B．whether C．that D．who【答案】C【解析】【分析】【详解】句意：——你看电视剧《人民的名义》了吗？——是的。

考查定语从句。

where哪里；who谁；which哪一个。

此句为非限定性定语从句。

在从句中visit缺少宾语，用关系代词作宾语；先行词为the museum，是物，that/which/不填，三个答案都可以。

故选C。

2．After graduating from Oxford, they met and mentioned the good old days________ they spent together.A．in which B．when C．that D．how【答案】C【解析】【详解】句意：从牛津大学毕业后，他们相遇并提到了他们在一起度过的美好的过去。

考查定语从句。

in which引导定语从句，通常等于where；when关系副词，当……时候，引导时间状语从句或定语从句，作时间状语；that可以作关系代词，引导定语从句，先行词可为人可为物，在从句中作主语或宾语；how不能引导定语从句,它可以作连接副词使用,引导名词性从句。

根据句意可知，此处后半句“they spent together”为定语从句，先行词为the good old days，在从句中作动词spent的宾语，此处需要填写定语从句的引导词。

比对选项，故选C。
