全部展开

只要弄清楚每个词语的意思，即可很清晰的分清这两个词语。
】Until ：直到....
】Unless ：除非（If not）。
I won't write to him unless he writes to me first.
我不会写信给他，除非他先写给我。是“直到”好还是“除非”好呢？很容易就可以感觉到“除非”好得多。
“我不写信给他直到他首先写给我。”读着都不通顺，
“我一直都没给他写信直到他写给我。”翻译为：I did not write to him until he had written to me. 理解这句话，是说实际上我写信给他了，在他给我写信了以后。

其实就是两个意思啦。
Unless是除非嘛、然后按意思讲的话，当然应该是除非更加通畅、
