Question

what does he look like意思等于how does he look like吗？

Answer 1

不等于。

what does he look like？他看起来怎么样？

how does he look like是一种错误的说法。

语法：

What does sb look like?

用于提问人的长相、外貌，意思是“他长得什么样?”,其中like是介词。

例句：

Q：What does Cathy look like?　卡西长得什么样?
A：She's tall, and she has black
hair. 她个子很高，一头黑发。
