unless 与 as long as / provided that的分别
(1)You can watch this film as long as / provided that you are not under 18.
这题可否变成:you can watch this film unldess you are not under 18.
unless 和 as long as / provided that 在一些意思看上去都可以使用的句子,有什麼可以分辨的吗?

很高兴为你解答!　　主要是意思的不同,unless=if ……not,“除非,如果不”；as long as=so long as,“只要”；provided that=supposing that=given that=if,“如果,假设,假如”.　　You can watch this film as long as / provided that you are not under 18.　　只要/如果你不是18岁以下,你就可以看这部电影.　　这题不可变成: you can watch this film unless you are not under 18.　　可以变成you can‘t watch this film unless you are under 18.另外,unless 你打错了.希望对你有所帮助.学习进步、快乐!
再问： �һ��ǲ��, you can watch this film unless you are not under 18. ��㲻��18��, ��Ϳ��Կ��ⲿ��Ӱ, ��Ϊʲ�N��? лл!
再答： unless本身就是否定的意义的词，引导的句子用肯定形式，一般用not……unless……翻译为“除非……才……”。
