除非衣服粘贴在烧伤面上，否则都要把衣服脱掉。如果需要的话，可以使用剪刀。
unless是连词，意为“如果不，除非”。在真实条件句中，unless引导的肯定条件状语从句，可以和if...not...引导的否定状语从句互换。

=If you dont change your mind，I won ’t be able to help you.
除非你改变想法，否则我不能帮助你。
I want you to keep working unless I tell you to stop.
=I want you to keep working if I don’t tell you to stop.
如果我没说让你停，你就得继续干。
注意：unless 不可用于假想的事情，因此当if...not引导非真实条件状语从句时，一般不可改用unless。
