两案三库-同步教案-高二牛津-第17周(it用法)

这个句型中，it指时间，而且表示时间的词语前没有介词（时间一般是具体时间）。主句和从句中的谓语动词在时态上是一致的，主句是will be，when从句用一般现在时代替将来时。

e.g. It was already 8 o’clock when we got home.

It will be late afternoon when they get there.

4）It be +时间+ that-clause

这个句型是个强调句型。

e.g. It was at 5 o’clock that he practiced playing the violin in the morning.

(原句是：He practiced playing the violin at 5 o’clock in the morning.)

比较：It was 5 o’clock when he started in the morning.（5 o’clock前没有介词，这个是定语从句）

5）It be + time + that-clause

这个句型属虚拟语气结构，不管主句中用的是is或was，that从句都须用动词的过去式或should+动词原形（但不及物动词通常用过去式），在time之前有时可以加上high或about以加强语气。

e.g. It is high time (that) he wrote a letter to his girlfriend.

It is time (that) we made people’s life a little easier. = It is time that we should make people’s life a little easier.

9、It/This/That + be + the first(second, third…) time + that-clause

这个句型表示截止到说话时为止的某人的一种经历，关键是注意time前有序数词，主句是一般现在时is时，从句要用现在完成时；如果主句用一般过去时was时，则从句须相应地用过去完成时。

e.g. This is the first time (that) these Europeans have visited the Great Wall.

It was the fifth time (that) I had paid a friendly visit to America.

10、在一些相对固定的词组中，没有特殊含义，经常不翻译。

e.g. He’s never really made it as an actor.作为演员，他从未获得过真正的成功。

It is my turn.轮到我了。
