Answer 1

(1): 1. Please let me know when the bank opens.when 引导状语从句，使用一般现在时代替将来时。即主将从现。此时when通常翻译成：当。。。的时候
翻译：当银行开门的时候，请告诉我。
2. Please let me know when the bank will open.
when引导宾语从句，做know的宾语。此时通常翻译成 ：什么时候
翻译：请让我知道银行什么时候开门。

区别(2): 1. We were eating when a friend of mine came to see me.

when此时翻译成，此时，正在。。。的时候。前面的主句要使用进行时态

翻译：我们正在吃饭，正在这时，我的一个朋友来看我。
2. When we were eating, a friend of mine came to see me.
when 翻译成：当。。。的时候
翻译：当我们吃饭的时候，我的一个朋友来看我

类似句: 1. I had hardly fallen asleep when suddenly the telephone rang.
这是固定搭配：hardly 。。。when。。。意思是：几乎未来得及就…；刚一…就…
翻译：我刚睡下电话就响了

2. I was about to leave when he came in.
when 也是当 正在此时讲
翻译:我正要离开，正在此时，他进来了

区别(4) 1. When I have corrected the papers, I will let you know the score.
这个也是主将从现，只不过使用的现在完成时来代替将来完成时。这个不是太常见。
当我批改完卷子，我会让你知道分数。
2. When I finish the book, I will return it to you.
这个是主将从现，与第一个是一样的。直接翻译了
当我看完这本书，我会还给你的。
