　　enjoy后面可接反身代詞(oneself),構成固定搭配enjoy oneself,意為“過得愉快、玩得高興” ,相當于have a good time.

　　你在聚會時玩得高興嗎?

　　— I enjoyed myself very much at the party.

　　我在聚會時玩得真開心.

　　1.enjoy后接動詞時必須接動詞的 -ing形式,不能接動詞原形或動詞不定式（to do）.

　　他喜歡踢足球.

　　[誤] He enjoys play football.

　　[誤] He enjoys to play football.

　　[正] He enjoys playing football.

　　2.enjoy后只能接表示褒義的詞組.

　　他母親身體不健康.

　　[誤] His mother enjoys very poor health.

　　[正] His mother doesn't enjoy good health.

　　can是情態動詞,后面加動詞原形

　　但在不同的句形里則不同,比如

　　we should do what we can to help others.

　　這里看似CAN后用了不定式.

　　其實是what we can 是do的賓語
