　　He appears to have caught a cold.

　　作賓語:

　　常與不定式做賓語連用的動詞有:want, hope, wish, offer, fail, plan, learn, pretend, refuse, manage, help, agree, promise, prefer, 如果不定式后面有賓語補足語,則用it作形式賓語,真正的賓語后置,放在賓語補足語后面,例如:

　　Marx found it important to study the situation in Russia. 動詞不定式也可充當(dāng)介詞賓語,如: I have no choice but to stay here.

　　He did nothing last Sunday but repair his bike.

　　動詞不定式前有時可與疑問詞連用,如: He gave us some advice on how to learn English.

　　作賓語補足語: 在復(fù)合賓語中,動詞不定式可充當(dāng)賓語補足語,如下動詞常跟這種復(fù)合賓語:want, wish, ask, tell, order, beg, permit, help, advise, persuade, allow, prepare, cause, force, call on, wait for, invite.

　　此外,介詞有時也與這種復(fù)合賓語連用,如: With a lot of work to do, he didnt go to the cinema.

　　有些動詞如make, let, see, watch, hear, feel, have等與不帶有to的不定式連用,但改為被動語態(tài)時,不定式要加to, 如: I saw him cross the road. /He was seen to cross the road.
