(必修)英语5二年级英语《Theme C Information Age and Our Life Computer Science Unit 5 Magic Internet Grammar》精品课教案

根据所假设的条件能够实现与否,可将条件句分为真实条件句和非真实条件句。

真实条件句所表示的假设是可能发生或实现的,句中的条件从句与结果主句皆用直陈语气,且这种句子主句是一般现在时时,从句用一般现在时表示将来时。

You will be late for class if you don’t hurry.

如果你不赶紧,上课就要迟到了。

I shall come if I want to (come).

如果我想来,我就会来。

非真是条件句也就是我们平常所说的虚拟条件句,所表示的假设往往是一种与事实的相反,是不可能实现的。句中条件从句与主句都用虚拟语气,时态自然也与真实条件句中的时态有所不同。

Studying the rule

Read the little poem below, paying special attention to the colored parts and trying to understand their meanings.

If all the seas were one sea,

What a big sea that would be!

If all the trees were one tree,

What a big tree that would be!

If all the axes were one ax,

What a big ax that would be!

If all the men were one man,

What a big man that would be!

If the big man took the great ax,

And cut down the big tree,

And let it drop into the big sea,

What a splash that would be!
