请教：My favirote fruit is apple. My favorite fruit is apples

如果是用apples 的话就应该是用 are而不是 is，
从语法上是这样的，
i like rabbit 和i like rabbits。这两种说法都应该是正确的

My favorite fruit is apples.
I like rabbits.

My favirote fruit is apple.
I like rabbits.

My favorite fruit is apples.
I like rabbits.
可数的名称不能光膀子出现，如，或是an apple,或是apples

my favourite fruit is apple.--apple表示泛指这一类东西，不是特指哪一个苹果，所以不用冠词。
i like rabbits.

第二句对了
