he would like 加s吗

不需要加s。would后面的动词，要用原形，would like to do。如果没有would，直接是he likes，这里like就要加s，因为是第三人称单数。

would like基本用法 


短语would like用来表达意愿，意为“想要、愿意”，和want意思接近，但比want语气委婉、客气。其后可接名词、代词宾格或动词不定式。其中，would是情态动词，常可缩写为’d。

如：Lucy would like some eggs.露茜想要一些鸡蛋。

We’d like to watch TV after school.放学之后，我们想要看电视。
