While引导让步状语从句通常放在句首的位置,也就是主句的前面。在句中意思是“虽然,尽管”,其近义词为:though和although三者语法意思差不多,但while语气稍微弱一些。 同时as也同while译为“尽管”,但as做引导词时句子需要倒装,而while不用。
1)while可以引导让步状语从句,表示“虽然”“尽管”, 例如: While the work was difficult,it was interesting。 虽然这工作很困难,却很有意思。 While I understand what you say, I can’t agree with you。 虽然我理解你的意思,但还是不同意。
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,那么从句的主语和谓语动词 be 都可以省略。例如: While he was felt uncomfortable,he still persevered。(=while felt uncomfortable, he still persevered。)虽然他觉得不舒服,但他还是坚持了下来。 He fell happy while he was doing his manual work。(=He fell happy while doing his manual work。)他做着做着手工作业就开心了。
3)while引导的状语从句还可以表示“某个动作正在进行的同时,另一个动作也在进行之中”。例如: While the music teacher was singing,the students were learning。 音乐老师唱歌时,学生们在学习。 While he was fishing,I was painting。 他在钓鱼的时候,我在画画。
4)as/while二者都可以译为“尽管”,但是as 做引导词时候,句子要倒装。例如: Try as he might,he couldn’t lift the iron。 尽管他可能尝试了,但他举不起这块铁。 而while就不需要倒装,例如: While he has many good points, Tom has his shortcomings。 虽然汤姆有许多优点, 但他也有缺点。
总结:While引导的状语从句在每年中高考都占据非常重要的位置,它作为从属连词既可以引导时间状语从句也可以用以引导让步状语从句,而且两者的词义都不一样,有些同学认为while的用法较为复杂,但其实只需做好两者的分辨,细心总结,while的用法其实也很简单。
