any other 的问题.

He is taller than any other boys in his class 。这句是用比较级来表达最高级
He is taller than any other boys in his class 。
=He is the tallest in his class.
=He is taller than the others in his class.
=He is taller than the other boys in his class.

应该是复数吧

没可能的
句子本来就是错的
any other本来就是在比较级+名词单数的
想后面加S的话就用other
不能加any

any other是"任何其他的"的意思后面就是跟复数啊~~~

呵呵这个简单 。 如果是He is taller than any other boys in his class 时，理解为他不是这个班上的学生，所以是比这个班上的所有学生都高 。
