介词和非限制定语从句

  定语从句,一个简单句跟在一名词或代词后(先行词)进行修饰限定,就叫做定语从句。下面是小编为大家提供的关于介词和非限制的定语从句,内容如下:

  非限定性定语从句:

  意义:

  非限定性定语从句起补充说明作用,缺少也不会影响全句的理解。在非限制性定语从句的前面往往有逗号隔开,如

  (1)The house,which I bought has a lovely garden. 我买的房子带着个漂亮的花园。

  (2)This novel, which I have read three times, is very touching. 这本我已经读过三遍的小说很感人。

  1.非限定性定语从句可将整个主句作为先行词, 对其进行修饰,这时从句谓语动词要用第三人称单数,例如:

  (1)He seems not to have grasped what I meant, which greatly upsets me.他似乎没抓住我的.意思,这使我心烦。

  (2)Liquid water changes to vapor, which is called evaporation. 液态水变为蒸汽,这就叫做蒸发。

  2. 在非限定定语从句中,有时as也可用作关系代词,若as在从句中作主语,其引导的句子可以放在句首,也可以放在句中。例如:

  (1)The boy has as much progress as we had expected. 正像我们所预料的那样,这个男孩取得了大的进步。

  (2) As everyone knows ,China is a beautiful country with a long history . 每个人都知道,中国是一个有着悠久历史的美丽国家。

  3. 在非限定性定语从句中,不能用从句做主语

  (1)The boys ,who are playing football ,are from Class One. 在踢足球的男孩们是一班的。

  (2)I helped an old man ,who lost his way ,yesterday . 昨天,我帮助了一个迷路的老人。

  介词的正确选择:

  1. 根据后面动词和介词的搭配关系选择。如:

  ①This is not the book of which the teacher spoke in class. (speak of 意为“谈论”,相当于talk about)

  ②The two things of which they felt proud were Jim’s gold watch and Della’s hair. (be / feel proud of 为固定短语,意为“以……自豪”。)

  2. 根据前面的名词的搭配关系选择。如:

  ①I’ll never forget the day on which I first met him. (表示具体的某一天,介词用on)

  ②The boy pointed to the direction in which he would run. (“朝……方向”,介词用in)

  3. 有时需同时考虑动词和介词的搭配关系及介词和名词的搭配关系。如:

  The clever boy made a hole in the wall, through which he could see what was happening inside the house.
