It has been/is ﹢ 时间段 since

Eg It has been 4 years since he smoked. 他戒烟已经4年了。

It has been 4 years since he began to smoke. 他吸烟已经4年了。

5. before

7. no sooner…than; hardly/scarcely…when 一…就…

Eg. We had no sooner arrived than the party started. 我们刚到,晚会就开始了。 在含有no sooner…than; hardly/scarcely…when 的句子中,若 hardly/scarcely,

no sooner 放在句首时,通常将主句中的助动词 had提到主句前,构成部分倒装。 Eg. No sooner had we arrived than the party started. 我们刚到,晚会就开始了。 归纳:No sooner/Hardly/Scarcely had sb done sth than/when…
