考点九:状语从句的引导词
1.时间状语从句
(1)when,while和as
当主句动作是瞬时的、从句动作是延续的时,用三者均可。when是最常用词;as强调主、从句动作同时或几乎同时发生;while从句的谓语必须是延续的。如:
John sang happily as he went along.
While/When John was sitting reading the book,I was working out my study plan.
When John arrived,I was cooking lunch.(不用while)
(2)till和until
用于肯定句时,主句谓语动词必须是延续的;用于否定句时,主句谓语必须是瞬时的;用于强调句型时,必须是it is not until...that...结构。如:
He waited until/till it was dark.
He didn't leave until/till it was dark.
It was not until I came back that he left.
(3)once和as soon as
once意为“一旦……,就……”,既表示时间,又含有条件意味。as soon as意为“一……,就……”,强调时间上紧接。如:
Once you have decided,tell me.
As soon as they arrived,they began to work.
(4)名词短语every time,the moment,the minute,the second等和副词immediately,directly等可作连词引导时间状语从句,instantly也可引导时间状语从句,意为“一……就……”。如:
