英语定语从句练习题20篇及解析
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。
这是一个定语从句，先行词是物invention，关系词可以用which或者that，但是先行词在从句做主语，that不可以省略。
故选A。
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。
定语从句专项练习题及详解50题
定语从句练习题附答案解析1．—Have you seen the film “Aquaman（海王）” I introduced to you last weekend?—Yes, but it was a little hard for me to understand.A．what B．which C．who【答案】B【解析】【详解】——你看了我上周给你介绍的《海王》这部电影了吗？——是的，我看了，但是对于我来说有一点难理解。
考查定语从句。
空前是完整的句子结构；且根据答语Yes, but it was a little hard for me to understand.可知，it代指Aquaman（海王）；问句和答句都在讲海王，故空后的句子用来修饰 Aquaman（海王），所以是定语从句，what不能引导定语从句，可排除A项；which先行词是物，who先行词是人。
本句的先行词是film，可排除C项。
故选B。
2．Dingtalk is a tool _______ is mainly used for teachers and students to have online classes during the fight against the novel coronavirus.A．which B．who C．where D．/【答案】A【解析】【详解】句意：钉钉是一个工具，主要用于教师和学生在抗击新型冠状病毒期间进行在线课程。
考查定语从句的关系代词。
which代指物，作主宾；who代指人，作主语；where哪里，关系副词；根据a tool是先行词，是物，在定语从句作主语，可推测出此处是“which”，故选A。
3．Mr. Lee is the only person ________ can help us with our math.A．who B．that C．which D．when【答案】B【解析】【分析】句意：李先生是唯一能帮助我们学习数学的人。
