后面常跟to do的：want, rufuse, forget, need, try, learn, like, agree, help, hope, wish, decide, begin, start
后常跟doing : finish, practise, be worth, be busy, keep on, be used to, give up, consider, suggest, can't help, feel like, enjoy, miss, mind
加do ：使役动词make, let感官动词look, see, hear, notice 等
有些词后面既可接动词不定式,也可接动名词,有些含义区别不大,
如：begin/start to do 与begin/start doing都表开始做某事.
有些则完全不同,
如：remember to do sth表示记得去做某事,
而remember doing则表示记得做过某事.
希望对你有帮助,如果还有疑问,欢迎你再问.
