like作为动词

当主语是第一人称（I）、第二人称（you）或第三人称复数（they）时，用like。例如：

I like reading very much.

You like playing basketball.

They like reading very much.

当主语是第三人称单数（he, she, it）时，用likes。例如：

He likes reading very much.

She likes to sing.

It likes playing basketball.

like作为介词

只能用be + like的形式。例如：

He is just like my elder brother.

希望这个口诀能帮助你更好地记住like和likes的用法!
