1 for是介词 不是被动的时候一样可以用 love sb for
2 虽然两个都是连词 但并不是所有的连词后面都一样 例如when afer 之类的就只能引导时间状语从句，这是单词的语法功能
3 本来就是时间状语从句 when 作为连词最主要的用法就是引导时间状语从句 如果只有它一个连词的话就只有时间状语从句...

1:这里的for是介词，好像没有love sb. for sth.的语法。
2：因为because和because of 意思差不多，但because加句子，而because of是加词语的 。
3：前面一句是一个由when引导的时间状语从句。when可以当特殊疑问词，还可以当引导词。可以组成时间状语从句。...
