anything but, nothing but 和all but 的区别

问：请问anything but, nothing but 和all but 之间有什么区别？谢谢。

答：anything but表示“决非”，等于never。nothing but表示“仅仅”，等于only。all but表示“几乎”，等于almost。它们大都作副词使用。比如：

1）  He is anything but a teacher. (他决不是教师。)

2）  Your attitude is anything but honest. (你的态度一点不老实。)

3）  The silver cup is anything but pure. (这个银杯不纯。)

4）  I am nothing but nobody. (我不过是个无名小卒。)

5）  Your composition is nothing but well-constructed. (你的作文只不过结构谨严而已。)

6）  Science is nothing but trained and organized common sense. (科学不过是训练获得的有条不紊的常识而已。)

7）  He is all but a fool. (他几乎有点傻。)

8）  The girl all but fell into the well. (那个女孩差点掉进井里。)

9）  The eye trouble all but drove me mad with fear of blindness. (眼病令我害怕眼瞎，因而几乎发狂。)
