应该是用WHEN啊,它引导时间状语啊
if引导条件状语从句，when引导时间状语从句！
先去看看什么叫从句吧
~~~~~~~~~~~~ 条件状语从句是表示主句动作发生的前提或条件的从句。引导条件状语从句的连词有if, unless, so/as long as, as/ so far as, on condition that, in case, suppose, supposing等。条件状语从句中的谓语动词一般要用一在时或过去时代替一般将来时或过去将来时。

if
if表示正面条件，意为“如果”。
If you ask him, he will help you.
如果你向他请求，他会帮助你。
Difficulties are nothing if we are not afraid of them.
如果我们不怕困难，困难就算不了什么了。？

when
if 是表条件的

You will see many stars in the sky when you come out at a fine night.
when引导时间状语.

when,用作关系副词，引导定语从句

when

You will see many stars is the sky_____you come out at a fine night.空里是填when还是if,为什么？ You will see many stars is the sky_____you come out at a fine night.答案是if,为什么不用when? 1)How many elephants did you see? mcknight when will I see you again how many people will be with you ?还是，how many people will with you? You will go{ }[see] Mr Brown in an office there. You will go{ }[see] Mr Brown in an office there. 高手帮忙翻译一下When Will I See You Again 2.They will be very _____ to see you here. I will see you at quitting time翻译
