what do you think of

what do you think of ...和how do you think of ...后面你要加上你要问的东西或事情等。一般没什么区别，都可以用。how do you think 一般是前面你们已经在讨论一件事情或者人、物，你直接征询别人意见，别人已经知道你在问的对象是什么。三个的意思差不多，没什么区别，都是“你认为xx怎么样/你对xx的想法、看法是什么”这种意思。

what do you think of ,how do you think of
都可以用,有宾语的话旧得加OF,what do you think of ,how do you think of没有具体的区别,就看你的习惯了

what do you think of......=how do you like......

应该是what do you think of

what do you think of就等于how do you like
