关于before until since 等的疑问
Few people will pay attention to their health ( ）they get disease.
答案说是until 我想问before能用吗?
We were chatting on the net ( ) the light went out.
.答案是when~我不知道能不能用until~还有这句翻一下~
Three years had passed( )i knew it答案是before 能不能用when...
1.Few people will pay attention to their health ( until）they get disease.
比较：Few people pay attention to their health ( before）they get disease.
2.We were chatting on the net ( when ) the light went out.
when 在这里是并列连词“其时” “就在这个时候” ,用来引出一个突发动作（后一分句）,until 无此用法
3.Three years had passed( before )i knew it
这里before 用在肯定句前表否定,when 无此用法
意为：不知不觉又是三年过去了
再如：
He left before I could say hello to him
我还没来得及同他打招呼,他就走了.第一句我知道了。。有点小转弯。。第二句的意思是什么？？？能不能翻一下。。然后这个属于什么状语从句？第三个的话用when的话可不可以翻译成这样。。当我知道它的时候三年已经过去了。。。第二部when是并列连词，前后是并列（等立）关系， 没有从句意为： 我们正在网聊，此时突然熄灯了。 （意外不？)第三句你说得有道理，我想说的是“对地道的说法欣然接纳吧，别用我们脑中固有的思维习惯去设置障碍。”
