We started early in order to arrive before dark.为了在天黑前到达,我们很早就动身了.

while的用法

while 用作连词时,有以下几种含义:

释义	用法	例句
当····的时候	引导时间状语从句	While I was watching TV, the bell rang.我看电视时,铃响了.
虽然,尽管	引导让步状语从句	While he is in poor health, he works hard. 虽然他身体不好,但他还是努力工作.

While he was tired, he went on working.虽然他累了,但他还是继续工作.(让步状语从句)

2.while引导让步状语从句时,如果从句的主语和主句的主语相同,且谓语含有be动词,那么从句的主语和be动词都可以省略.

While he was ill, he went there.(＝While ill, he went there.)虽然他病了,但他还是去那里了.

用 could 提出请求和征求许可

本单元的核心语法是用情态动词could提出请求和征求许可.具体如下:

1.用 could 提出请求

常见的结构是“Could you(please)...?”,意为“你能······吗?”或“请你······好吗?”,是一种比较客气、有礼貌地提出请求的方式.如果同意对方的请求,可以用OK.或No problem.等来回答.如果不同意对方的请求,可以用Sorry, I can't.等来回答,并以委婉的方式来解释原因.

-Could you please open the door?请你把门打开好吗?

-Sure.当然可以.

2.用could征求许可

常见的结构是“Could I...?”,意为“我能／可以······吗?”.此时肯定回答和否定回答都不用could,习惯上肯定回答用may、can等;否定回答用can't或mustn't(语气重).有时也可避而不用.

-Could I smoke here?我可以在这里抽烟吗?

-No, you can't. Look at the sign “No Smoking”！不,你不能.看那个“禁止吸烟”的标牌！
