该句型中that后从句应当用虚拟语调，值得注意是①常用过去时态表达虚拟．②有时也用should+动词原形，should不能省，常译为＂是（正是）．．．时侯．．．＂

Itistimethatchildrenshouldgotobed.

=Itistimethatchildrenwenttobed.4.It引导时间句型第32页2).Itisthefirst(second...)timethatsb

has/havedonesth.

Itwasthefirsttimethatsbhaddonesth.ItisthefirsttimeIhavebeenhere.

=ThisisthefirsttimeIhavebeenhere.3).Itis....since...。

该句型主要用作处理瞬间动词完成时，又要和表达一段时间时间状语连用问题，主句中是时间作表语，其时态是目前时或完成时，since引导从句一般是一般过去时态，并且是瞬间动词。假如主句是一般过去时，从句则用过去完成时。

Itis(hasbeen)5yearssincehisfatherdied.第33页4).Itis...when...。

该句型中when引导是一种时间状语从句，主句中it指时间，表语由详细时间充当，常译为＂当．．．时候，是．．．＂

Itwas5o’clockwhenhecamehere.5).Itbe...before...

该句型主句中it指时间，主句中时态常是将来一般时或过去时两种时态．主句中表语多是long，notlong，3days，2weeks等表达时间段词或短语，常译为“没过多久才”。否认为“没多久……就”.
