IT在表示时间时要注意以下的一些句式：

① It be … since ...该句型主句中的 it 指时间,主句中是时间作表语，其时态是现在时或完成时，since 引导的从句通常是一般过去时态。如果主句是一般过去时，从句则用过去完成时。

It was 5 years since I had enjoyed myself so much.

It is ( has been ) 5 years since I smoked.

②It be ... when ...该句型中的 when 引导的是一个时间状语从句，主句中的 it 指时间，表语由具体的时间充当。常译为“当……的时候，是……”。
