自考英语:except的用法
自考英语:except的用法 except除去，除掉
（1）与but一样，expect后面除了像其他介词一样可跟名词和代词外，还可跟介词短语、不定式和从句。

注意：在do nothing/everything/anything except的句型中，其后的不定式多省略to。

(2)except和except for的区别
except后面的成分和主语或宾语的成分属于同一种类，而except for后面的成分跟主语或宾语的成分不属同类。

(3)but和except的区别
but后面的成分一般不重要，而except则强调它后面所跟的成分，but多放在否定句或否定词nobody,nothing等之后，而except则不一定。
For a while,there wasn’t anything to do for either of us but drink beer.
My papers seem to be everywhere except where they ought to be.
