一道英语题,求高手解答

Question

I rarely went to the movies and i forgot __________to eat in a fancy restaurant
答案是填 what it was like为什么不是how it was like？二者有什么区别？

Answer 1

like在此是介词，需要有它的相应的宾语，只有名词、代词才可以充当宾语，what是代词，how是副词，所以是what it was like,而不是how it was like,另外从词意上二者也不相同，what 是“什么”，how是“如何”，回答完毕。

Answer 2

这里的was like是像。。。及物的后边要接一个宾语，what是名词性的可以做宾语，how是形容词性的不能做宾语

Answer 3

从语法看
i forgot what it was like to eat.我忘了它是什么味道。
i forgot how it was like to eat. （没有这种用法）
i forgot how it was like. 我忘了它是怎么样的。
