浏览:177 发表时间:2019-09-29 16:13:10

  大家不难发现SAT语法真题中关于as的考察还是比较多的。这部分的SAT语法考点大家需要了解。

  as作为从属连词引导时间状语从句

  表示“当……的时候”或“一边……一边”,强调主句的动作和从句的动作同时发生。如:

  I saw him as he was getting off the bus. 当他下公共汽车的时候我看见了他。

  The boy was singing a popular song as he was bicycling. 这男孩边骑车边唱歌。

  As she grew older, she became less active. 当她长大一点的时候,就变得不那么活泼了。

  as作为从属连词引导原因状语从句

  as 引导的原因状语从句常放在主句前,表示“因为,由于”。如:

  As she is a model teacher, she gives a good example to others. 因为她是一名模范教师,她给其他人树立了一个好的典范。

  As he wasn’t ready in time, we went to the cinema without him. 由于他没有及时准备好,我们就去看电影了,没有等他。

  as作为从属连词,引导让步状语从句

  as引导让步状语从句比较特别,它要求将主语和谓语或谓语的一部分倒装。如:

  Try as she may, she never succeeds. 尽管她很努力,但总是不成功。

  Much as I admire Mr. Wang as a poet, I don’t like him as a man. 尽管我喜欢王先生的诗歌,但我不喜欢他的为人。

  注:当倒装后置于句首的名词为单数可数名词时,习惯上不带冠词。如:

  Boy as he was, he was made king. 尽管他还是个孩子,却被立为国王了。

  与其他词搭配使用构成从属连词引导从句

  1. as if / as though。表示“好像,仿佛”,引导表语从句或方式状语从句。如:

  It looks as if / as though it is going to snow. 看起来要下雪啦。

  2. as [so] long as。“只要”,引导条件状语从句。如:

  As [So] long as you can keep away from them, you will be safe. 只要你能远离他们,你就安全了。

  I’m happy as long as you are happy. 只要你幸福,我就感到幸福了。

  3. as [so] far as。表示“在……的范围内”,引导限制状语从句。多用于下列结构:as [so] far as I know(据我所知),as [so] far as I can see, as [so] far as I’m concerned(依我看)。如:

  As [So] far as I know, the couple have been abroad for about five years. 据我所知,这对夫妇已经出国约五年了。

  There’s only one thing to be done now, as far as I can see. 依我看。现在只有一件事情要做。

  4. as soon as。表示“一……就”,引导时间状语从句。如:

  As soon as he got off the plane, he telephoned her girl friend. 他一下飞机就给他的女朋友打了个电话。

  有关SAT语法中as的用法内容就给大家介绍到这里了,希望同学们能够掌握这些SAT语法考点。
