举个if的从句的例子并翻译（没有就说没有）

if 引导的条件状语从句
We will go to the park tomorrow if the weather is fine.
（这个就是一般的很普遍的句子）

还有一个就是if的虚拟语气。我不知道这个在不在你想问的范围内，不过我还是说一下吧，虚拟语气说得简单点，就是三种。
1.与现在事实相反
If I knew his number,I would tell you now.
2.与过去事实相反
If I had knew his number,I would have told you.
3.与将来事实相反
If he would come tomorrow,I would tell him the truth.
= If he were to come tomorrow,I would tell him the truth.
= If he should come tomorrow,I would tell him the truth。

还有什么需要补充的你可以提出来哦。

we will go shopping if the wather is sunny tomorrow
如果明天天气晴朗我们将去购物.

If tomorrow isn't rainy I will walk to school.
I will come back soon If there isn't anybody fighting.
If I were you I would never be so follish.
If mom find you broken it She will be crayz.
I will wait here if you go hiking with me.
