有一读者问：
(1)He is taller than any other boy in his class.
在这一句中，要是掉了other，就被认为不对，可是也有一些不用other的句子，如：
(2)Tom is cleverer than any of the students in his class.
(3)It's bigger than anything anyone can imagine.
该如何解释？
上面举的四个例句都是正确无误的英语。例（1）中any之后应有other，这是许多语法家们的看法，我们也认为这是比较规范的英语，在我国一般英语教学中尤应遵照之。但同时也应注意到any后省去other的情况并不罕见，如：
(4)London is more densely populated than any city in the world.
(5)The winter was colder than any he had experienced.
例（2）一般并不认为是错误的，这是因为any在此=all，全句=Tom is the cleverest student in his class.。
