2017英语专四语法考点:定语从句

2016-12-26 17:59:03来源:网络

  As 引导非限定性定语从句时与which的区别:当主句和从句语义一致时,用as;反之,用which。

  如:He made a long speech, as was expected.

  He made a long speech, which was unexpected.

  Tom drinks a lot every day, which his wife doesn’t like at all.

  (3)但是,如果从句和主句的动作在将来不同的时间发生,则两部分都要用来将来时,

  注:⑤在“介词+关系代词”的结构中,也可用复杂介词,如:by means of (用,依靠),as a result of (作为结果)等:

  例:I have three children, one daughter and two sons, all of whom graduated from the same university .

  我有三个孩子:一个女儿、两个儿子,他们都毕业于同一所大学。

  The police, in whom I have great confidence, are trying to find out who did it.

  我对警察有极大的信心,他们正在努力寻找是谁做的这件事。

  This is the part of the river in which I like to swim.

  (in which=where)

  我喜欢在这条河里面游泳,这就是(我喜欢游的)那个地方。

  The man from whom you bought the house is my uncle.

  你从他那里买下房子的那个人是我叔叔。

  This is the desk by means of which he jumped over the wall.

  这就是他用来跳过墙去的那张桌子。

  She was running a fever, as a result of which she failed in the exam.

  她当时正发烧,所以考试失败了。

  He is the man from whose house the picture was stolen.

  他就是那个家里的画被偷了的人。

  注:⑥一个先行词后面可以跟一个以上的定语从句,这种现象叫双重关系从句:

  例:Here are some words which are often used but which are very confusing.

  这里有些常用但非常混乱的词。

  He is the only person that I can find who is able to solve the problem.

  他是我能找到的唯一解决这个问题的人。
