2015届高考英语二轮专题复习课件：第12讲 定语从句

1、,例 The settlement is home to nearly 1,000 people, many of _ left their village homes for a better life in the city. A. whom B. which C. them D. those,A,解析此处考查的是介词+which/whom引导从句。由many之前的逗号和选项特征，此处是主从句关系，需要连词。由于先行词是“1,000 people”，表示人，故用whom。句意为：这里居住着将近1000人，他们中的许多人都背井离乡去城市追求更好的生活。,第12讲 定语从句,例 Ive bec

2、ome good friends with several of the students in my school _I met in the English speech contest last year. A. who B. where C. when D. which,解析该题关键在于找准先行词，是my school还是the students。根据从句的句意以及met缺少宾语可判断先行词是人，故选关系代词who/whom。,A,例 Stephen Hawking believes that earth is unlikely to be the only planet _ life

3、 has developed gradually. A. that B. where C. which Dwhose,解析先行词为planet，定语从句中缺地点状语，故选where，等于on which。,B,例 In China, the number of cities is increasing _ development is recognized across the world.

4、间是所属关系，所以选whose。,C,例 The house I grew up _ has been taken down and replaced by an office building.

5、：考生要把关系代词指代的先行词代入到定语从句，把定语从句还原为一个完整的简单句，再判定先行词在句子中的成分，由此来选择正确的关系代词。先行词指人，则用who/ that, whom作宾语；先行词指物，则用which, that。 注意关系代词的省略：关系代词若在限制性定语从句中作宾语并且前面无介词时，关系代词可省略，其他情况不可省。,关系代词,2020/6/26,I tried to get out of the business, _ I found impossible. when B. what C. that D. which My friend showed me round the
