如果while后面要接动词,则必须用doing,如果while后面接句子或短语,则不用。
while的用法
1、作名词用,表示“一会儿”。
例句:They walked back together, talking all the while (= all the time) .
他们一起边走边聊着回去的。
2、作连词,引导状语从句。
例句:While my heart is willing, my flesh is weak.
心有余而力不足。
3、作并列连词用,意为“然而”,表对比关系。而but表转折。
例句:The son was having a good meal at home, while the parents were working in the fields.
儿子在家吃好饭而父母却在田里辛勤劳作。
while和when的区别
1、while只能表示某一段时间,when表示某一点时间
例如:
While Jim was mending his bike, Lin Tao came to see him.
正当吉姆修自行车时,林涛来看他。
Sunday is the only day when I can relax.
星期日是我唯一可以休息的日子。
2、while引导的时间状语从句多用进行时态,而when引导的时间状语从句多用一般时态。
例如:
While they were talking , the bell rang.
正在他们谈话的时候,上课铃响了。
I was doing my homework when my mother came back home yesterday evening.
昨天晚上妈妈回家的时候,我正在做家庭作。
