My favourite food is/are...

问题描述:

My favourite food is/are...
有这么几个句子,还都比较常见...有点迷茫,哪个是对的.请指教,
My favourite food is apple.
(这句我个人觉得不对,问题出在apple上,因为可数名词表示泛指一类时,要么就是apples,要么就是the apple)
My favourite food is apples.
(这句呢,is通常认为后面是跟单数的?)
My favourite food are apples.
(这句are对应复数,看起来好像没啥问题...不过问句肯定是What is your favourite food?的话,那是否意味着答句的谓语一定要用is呢?问题又就纠结到前面两句去了.不解,不解...按我目前所掌握的语法知识,好像都有说不通的地方额...)

可数名词也可不用a/an,the,或是复数s.
美国人常说I like to eat cake and ice cream.
cake 既没加冠词也没加S.语言不是科学.语言是文化,是习惯.如果是人们常说的就是地道的.
My favourite food is apple.这是人们常说的.
