if引导的条件状语从句 主将从现 哪个是主句 哪个是从句

Question

如题所述

Answer 1

紧跟在if后，被if引导的那个句子是从句。含有主语的句子是主句。
e.g. He will go hiking if it doesn't rain tomorrow.
从句：it doesn't rain tomorrow.
主句：He will go hiking.
e.g. 2 If I were you, I would have stopped him directly.
从句：I were you
主句：I would have stopped him directly.追问

我能问你点问题么

while和when后面接的是从句还是主句

追答

时间状语从句。

Answer 2

你已经说了：
if引导的条件状语从句
if从句就是从句；后面的就是主句。
如：
If it rains, I will stay home.追问

好像是哈

那while和when呢

追答

when, while, as, as soon as, once等引导的时间状语从句
if, unless, as long as等引导的条件状语从句
这两种状语从句用一般现在时表示将来，而主句用一般将来时。
如：
When he comes, I will leave.
