　　　　　　　　　　　后跟动词-ing形式还是不定式？

　　英语中后跟动词-ing形式或不定式作宾语的动词大致可分为四类：

　　一、有些（短语）动词后可跟动词-ing形式作宾语，但不能跟不定式作宾语。这类动词有：admit, avoid，can't help, consider, enjoy, fancy, feel like, finish, give up, imagine, involve, mention, mind, miss, practise, prevent, put off, quit, risk, suggest等。

　　二、有些动词后可跟不定式作宾语，但不能跟动词-ing形式作宾语。这类动词有：afford, agree, aim, appear, arrange, ask, beg, care, choose, dare, decide, demand, expect, fail, happen, help, hope, manage, offer, plan, prepare, pretend, promise, prove, refuse, seem, wait, wish等。

　　三、有些（短语）动词后既可跟不定式作宾语，又可跟动词-ing形式作宾语，意义上区别不大。这类动词有：begin, can't bear, continue, fear, hate, like, love, prefer, start等。

　　四、有些（短语）跟不定式作宾语与跟动词-ing形式作宾语，意义是有区别的。这类动词有：remember, forget, regret, stop, try, mean, need, want, go on等。如：

verb + doing (meaning) + to do (meaning)

mean to involve or will result in to intend to do something Flying to another continent usually means spending hours in a plane. I meant to go running this morning, but I overslept.

need to require something to be done to it to feel it necessary to do something That floor is dirty. It needs washing. I feel sick and need to see a doctor.

want

need to be done to feel that you would like to do something The carpet really wants cleaning. What do you want to eat?

go on to continue to stop one action and change to another They went on playing even though the weather was bad. After he had explained the theory，he went on to give us several examples. 注：need和want 表示"需要"时，其后既可以跟动词-ing形式的主动式表被动意义，也可跟动词不定式的被动式。如：

The plants want watering / to be watered daily. 这些花草需要天天浇水。
