用books 还是book

在any后的名词可复数可单数,都是正确的,单数时有"任何一"的意思.

在做题的时候,原则是any other 后面一定用单数.

book
any后是不加名词复数的，记住！

Singular or plural?

Any used as a pronoun is followed by a singular or plural verb depending on the intended meaning:

Any of these suggestions is acceptable. [i.e., any one of the suggestions is acceptable].
Are any of the children [i.e. more than one of several children] coming? (Is any of the children coming? implies that one is expected, with uncertainty as to which).

In formal writing, avoid use of the adverb any alone after a verb, as in The criticism was harsh, but we didn't complain any, where any can be dropped or replaced by "at all."
