复合句中as用法详解

 

  as的用法灵活,词义繁多,特别是在复合句中更能体现其用法的多样性和灵活性,但如果同学们能正确掌握as的词性和词义,是不难掌握其用法的。

 

  一、as用作关系代词引导定语从句

 

  1.as引导非限制性定语从句,一般不指代某个具体的名词或代词,而是代表整个主句或主句的一部分。这种从句可放在主句之前,也可以放在主句之后,有时还可以放在主句的中间。如:As is reported in the newspapers,talks between the two countries are making progress.正如在报纸上所报道的,两国间的谈判有所进展。Grammar is not a set of dead rules,as has been said above.如上所说,语法不是一套死条文。Spiders are not insects,as many people think,nor even nearly related to them.蜘蛛不是昆虫,尽管许多人都这样认为,它甚至与昆虫几乎没有联系。2.as引导限制性定语从句,主要用于the same…as(与……相同),such…as(像……一样),as…as(与……一样)。如:(与She knew he felt just the same as she did.她知道他的感受和她一样。Such a man with a good temper as Mr.Li is easy to get along with.像李先生这样好脾气的人是容易相处的。He smokes as expensive a cigarette as he can afford.他抽一种他买得起的最贵的烟。

 

  二、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 she grew older,she became less active.

 

  三、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。

 

  四、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:Old as he is,he is still full of energy.尽管年纪大了,但他依然精力充沛。Try as she may,she never succeeds.尽管她很努力,但总是不成功。Try as she may,she never succeeds.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。

 

  五、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。He looks as if/as though he had seen a ghost.他的脸色看起来好像他看见了鬼。He talks as if/as though he knew everything about it.他说话的口气好像他已经全部都知道了。<it.about everything>

 

  2.as[so]long as。“只要”,引导条件状语从句。如:<it.about everything>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。I’m happy as long as you are happy.

 

  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:(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。He started as soon as he received the news.他一得到消息就出发了。

 

  总之,由于as的用法复杂,同学们在学习时一定要注意比较其在不同句子中的作用,判断其连接的是什么样的从句,多做一些关于相关练习,这样便可掌握其用法了。
