about to do.when...与此类句型意思相同的句型有哪些啊?
答
be going to和be about to意思相近,when与while相近,但when指某一时间点,那个时间,as the time正当那个时候,如when I sleep;while指时间段,那段时间里,while可换成during the time,要加表示时间段的从句,动词用be加动词ing形式,如whileI was sleeping。
答
这个考点我把它总结为【用when引导时间状语从句的句型结构搭配】:
be about to do sth when 刚要,即将;正要做某事,突然发生其他事
be doing sth when 正在做某事突然
had done sth when 刚刚做过某事突然
be at the point of doing sth when 就在做某事的关键时刻突然
scarcely...when/hardly...when 几乎未来得及就…;刚一…就…
no sooner...than 一…就…
