分析一下if引导的从句的句型是什么
1个回答

总的来说,if 引导的从句有三种用法

1.用于真实条件句

例如:

If you are at home,I will go to see you.

If you work hard at it,you can get success.

表示,只要按这样得条件去做,结果是肯定的.

2.用于虚拟条件句

例如:

If I were you,I wouldn't go there.

If the sun rose from the west,I would call you Dad.

表示,条件是假设的,不真实的,因此,其结果也是不可能实现的.

注意句中谓语有所变化

3.用于名词性从句,意思等于whether or not 表是否之意.

例如:

It doesn't matter if you go to attend the meeting.

你是否参加会议没关系.
