英语定语从句怎么做选择题啊?

1、that与which的区别.1）用that而不用 which的情况：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先行词既有人又有物时.e.g.There is nothing that can prevent him from doing it.没有什么能阻止他不干那件事.The first place that they visited in Guilin was Elephant Trunk Hill.在桂林他们所参观的第一个地方是象鼻山.This is the best film that I have ever seen.这部电影是我看过的最好的一部.Mr Smith is the only foreigner that he knows.史密斯先生是他认识的唯一的外国人.2）用which而不用 that的情况：①引导非限制性定语从句；②代表整个主句的意思；③介词 + 关系代词.e.g.He had failed in the maths exam,which made his father very angry.他数学考试没有及格,这使他的父亲很生气.This is the room in which my father lived last year.这是父亲去年居住过的房子.3）as引导定语从句时的用法①as引导限制性定语从句通常用于the same … as,such … as结构中.e.g.I want the same shirt as my friend’s.我要一件跟我朋友一样的衬衫.Such machines as are used in our workshop are made in China.我们车间使用的这种机器是中国制造的.②as引导非限制性定语从句既可放在主句之前,也可放在主句之后,用来修饰整个句子.通常用下列句型：as is known to all,as is said,as is reported,as is announced,as we all know,as I expect 等.e.g.As I expected,he got the first place again in this mid-term examination.正如我所预料的那样,他在这次期中考试中又获得了第一名.3）as 引导非限制性定语从句时与which的区别①当主句和从句语义一致时,用as；反之,用which来引导非限制性定语从句.e.g.He made a long speech,as we expected.He made a long speech,which was unexpected.②当非限制定语从句为否定时,常用which引导.e.g.Tom drinks a lot every day,which his wife doesn’t like at all.2.关系代词在从句中作主语时,从句的谓语动词单数还是用复数应由先行词决定.e.g.The man who lives downstairs speaks English fluently.住在楼下的那个人英语说得很流利.The students who are in Grade Three are going to climb the hill tomorrow.3.定语从句有时不直接紧靠先行词,中间由一个定语、状语或谓语隔开.e.g.There is an expression in his eyes that I can’t understand.4.引导定语从句的关系副词有时可以用“介词 + which”来代替.e.g.October 1,1949 was the day on which ( = when ) the People’s Republic of China was founded.5.当定语从句中谓语动词是带介词或副词的固定短语动词时,短语动词的各个固定部分不要拆开.e.g.The sick man whom she is looking after is her father.6.介词在关系代词前,只能用which和whom,且不能省略；介词在句尾,关系代词可有which,that,whom,口语中也可用who,且可省略.e.g.The man (whom/ who/ that) you were talking about has come to school.
