幻灯片 32【点津】
以上句型中若主句为将来时态，从句则用一般现在时态；若主句是一般过去时态或过去完成时态，则从句用一般过去时态。

----
幻灯片 33【拓展延伸】“It be + 时间 + 从句”句式归纳
(1)It is/has been+时间段+since+一般过去时
It is/has been 5 years since he came to our school.
这一句型可引申为：It was+时间段+since(从句用过去完成时)
It was 10 years since he had arrived in China.
需要注意的是since从句的谓语动词一般是非延续性动词，但有时也可用延续性动词或表示状态的词，此时需要注意句子的翻译。试比较：
----
幻灯片 34It is three years since she came to our class.
她来我们班已经有三年了。
It is three years since she was in our class.
她离开我们班已经有三年了。
总之，在翻译此类句子的时候我们要记住一点，那就是“自从这一动作或状态结束以来”，只要记住这一点我们就比较好理解句子了。

It was already eight o’clock when he came back home.

幻灯片 36 (3)It/This/That is+the+序数词+time+that从句(从句用现在完成时)
It/This/That was+序数词+time+that从句(从句用过去完成时)

It was the second time that he had been out with her alone.
(4)It is + (high) time + that +主语+did/should do(虚拟语气)
It is (high) time (that) we stopped/should stop pollution.
----
幻灯片 37 (5)It be +时间状语(被强调部分)+that. . .
It was at 6 o’clock that we heard the noise. （强调句）
判断类似句式是不是强调句最简单的方法是：当表示时间的词前有介词或者后有副词时，一定是强调结构，必用that。
----
