He likes me为什么like要加s

Question

some fish为什么不用eat？He comes SHEN YANH为什么come要加s？He often plays golf为什么不能写成He plays golf often？

Answer 1

He likes me. like 加s是因为he属于第三人称单数，第三人称单数后面的动词要用三单形式。he comes Shenyang，同解。
some fish不用eat，而是用have，这属于用语习惯问题，实际上也可以用eat，如What did you have this lunch? I ate rich,broccoli.
He often plays golf, 属于英语用语习惯，从语法角度上讲，副词often也可以放在句末。
