连词while的四关键点
一、考查表示时间的用法,其意为“当……的时候”。如:
We must strike while the iron is hot. 我们要趁热打铁。
Stand still while I take your photograph. 我给你拍照时站着不要动。
Have we got enough books to read while we are on holiday? 假期里我们有足够的书看吗?
Were there any calls for me while I was out? 我出去的时候,有人来过电话吗?
She hates anyone listening while she is telephoning. 她打电话时不愿让任何人听。
二、考查表示让步的用法,其意为“尽管”“虽然”。如:
While the work was difficult, it was interesting. 虽然工作有难度,但很有趣。
While I understand what you say, I can’t agree with you. 虽然我理解你的意思,但我还是不同意。
三、考查表示对比的用法,其意为“而”“但”。如:
Some people waste food while others haven’t enough. 一些人糟踏食物而另一些人却食不果腹。
I went swimming while the others played tennis. 我去游泳,而其余的人则去打网球了。
Prices are rising sharply, while incomes are lagging far behind. 物价飞涨而收入却远远落后。
注:这样用时,while引出的句子通常位于末,但有时也可位于句首。如:
While most children learn to read easily, some need extra help. 大多数儿童学会阅读很容易,有一些儿童却需要特别帮助。
While Deauville is a holiday resort, Trouville is more of a working town. 特维尔是个度假胜地,而特鲁维尔更多的却是个工业城市。
四、考查其省略用法,即主句与从句主语相同,且从句谓语动词含有动词be时,通常可省略从句主语和动词be。如:
While (he was) in prison, she wrote her first novel. 她在狱中写出了第一部小说。
He had strayed from home while still a boy. 他小时候就离开家到处流浪了。
He fell asleep while (he was) doing his homework. 他做着做着功课就睡着了。
