I like dogs best .对dogs提问what is your favorite animal还是what are ... animals

答案What is your favorite animal?
如果是第二个答案，那么，回答肯定是，I like dogs and cats best.
就是肯定有两个以上的答案了
而且，这和最喜欢的动物，矛盾

肯定对哦

肯定是which is your favorite+一个限定的范畴
因为favorite是“最喜欢的”意思，如果用are，那说明你在一个范畴内最喜欢的是两个及两个以上的东西，不合逻辑

这里用what is your favorite animal?
还有一种提问方法是what animal do you like best?

好像是which animals do you like best吧

答案是：What is your favorite animal?
或者what animal do you like best?
或者which animal do you like best？
或者What animal is your favorite ?
