你妹妹喜欢吃什么 英语

单数：What does your sister like to eat?
复数：What do your sisters like to eat?

我个人认为：

like + doing 的确是表示喜欢做什么事情，但是这是个习惯动作。喜欢吃什么其实不是习惯性动作的。

如果是想表达她平时喜欢吃什么，应该说：What kinds of food your sister likes?

如果是你要请她吃饭，询问她喜欢吃什么，应该说：
What kinds of food your sister prefers to have?

我在国外，直接说eat这个词其实是很少的。都是have dinner，而不是eat dinner。

希望能够帮助到你

What does your sister like eating?
What does your sister like to eat?

注意:like doing sth 喜欢做某事 表“经常性的爱好”
like to do sth 喜欢做某事 表“具体某一时的兴趣或爱好”

祝你进步！
