英语定语从句练习题50篇及解析
定语从句练习题附答案解析1．— At present young people prefer WeChat to keep in touch with their friends. — Yes. It seems to be the best way of communication________people like.A．that B．which C．who D．what【答案】A【解析】【详解】句意：——现在年轻人更喜欢用微信来和朋友保持联系。
——是的。
这似乎是人们喜欢的最好的通讯方式。
本题考查定语从句。
that引导定语从句，修饰事物；which引导定语从句，修饰事物；who引导定语从句，修饰人；what引导名词性从句。
此处是定语从句，先行词communication是事物，因此排除CD两项。
先行词前有形容词最高级best修饰，因此用that引导定语从句，故选A。
2．The factory we’ll visit next week is not far from here.A．where B．what C．which【答案】C【解析】【详解】句意：我们下周要参观的工厂离这儿不远。
考查定语从句。
where指地点，作状语；what不可以引导定语从句；which指物，作主语或宾语。
分析句子可知，此处是定语从句，先行词是The factory指物，在其后的定语从句中作visit后的宾语。
故选C。
3．Harry potter is the best movie _________ I have ever seen.A．which B．who C．what D．/【答案】D【解析】【详解】句意：《哈利波》特是我看过的最好的电影。
考查定语从句。
在定语从句中，先行词是物时关系代词用that或which，此句先行词“movie”是物，可知排除B和C；先行词“movie”被最高级修饰，可知关系代词只能用that，当关系代词在定语从句中作宾语时，that可省略。
定语从句练习题50道
定语从句练习题附答案解析1．A kind of shared bike ________ is called bluegogo is getting more and more popular in Chengdu.A．it B．who C．which D．what【答案】C【解析】【详解】句意：一种叫做bluegogo的共享自行车在成都越来越受欢迎。
考查定语从句。
分析句子结构，可知，此句是一个定语从句，先行词是shared bike，指物，在从句中作主语，用关系代词which，故选C。
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．—Sichuan is home to pandas ________ are known as the national treasure of China.—Now as long as people see the picture of panda, they will think of China. A．which B．who C．what【答案】A【解析】【详解】建议：——四川是熊猫的故乡，熊猫被称为中国的国宝。

考查定语从句。
根据句子结构可知，空格后是定语从句，修饰名词hero。
whom关系代词，先行词是人，在从句中作宾语；which先行词是物，在从句中作主语或宾语；who先行词是人，在从句中作主语或宾语；what不引导定语从句。
从句中缺少主语，先行词是人，故选C。
2．I fell in love with the house ________ door is golden.A．whose B．which C．that【答案】A【解析】【详解】句意：我爱上了那栋门是金色的房子。
考查定语从句。
whose谁的，关系代词，指代人或者物的所属关系，作定语；which哪一个，关系代词，指代物，做主语或宾语；that关系代词，指代人或者物，做主语或宾语；根据句意理解及句子结构分析可知，这里先行词是house，指物，且在从句中作定语，指的是“房子的门”，所以应该用whose，故选A。
【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；还有一个关系词whose用的也比较多，指代所属关系，可以指代人也可以指代物，在从句中做定语，做题时要注意，本题就是指代所属关系，所以用的whose。
3．The Palace Museum is the best place ________ I’ve ever visited.A．who B．when C．that D．where【答案】C【解析】【详解】句意：故宫是我参观过的最好的地方。

Whom指人，作从句的宾语；which指物，作从句的主语或宾语；who指人，作从句的主语或宾语；whose即指人也指物，作从句的定语，后跟名词。
根据动词“catches”可推断关系词作从句的主语，而“the girl”指人，故选C2．The “Share-go”cars ________ use electricity not only look cute but also are environmentally-friendly.A．which B．who C．what【答案】A【解析】【详解】句意：使用电力的“共享”汽车不仅看起来可爱，而且环保。
考查定语从句。
which关系代词，指代先行词是物的词；who关系代词，指代先行词是人的词；what不能引导定语从句。
根据题意可知，空格上填的是一个关系代词，指代的是前面的cars（指物），故使用关系代词which来引导。
故选A。
3．—How do you like Tibet?—This is the most fantastic place ________I’ve been in the past few years. A．that B．which C．to which【答案】C【解析】【详解】句意：——你觉得西藏怎么样？——这是我过去几年去过的最美妙的地方。

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。
