61 不定式作賓語：動詞+ to do sth. Track 061
（1）跟在一個及物動詞后面作賓語
此時句子有以下兩個特點：
1）句子主語與不定式的邏輯主語一致，即不定式和謂語動詞所表示的動作都是由全句主語發(fā)出。
2）這時句子的謂語動詞多是描寫態(tài)度；不定式的動詞則說明行為。
例句
a. I hope to see you again.
b. This company refused to cooperate with us.
c. He promised not to tell anyone about it.
英語中常接動詞不定式作賓語的動詞有：
agree appear beg begin dare decide
expect fail forget happen hate hesitate
hope intend like love manage mean
prefer prepare pretend promise propose refuse
regret remember seem start swear try
want wish
（2）連接代詞 (what， who， which)或連接副詞 (how， when，where)及連詞whether后可接一個帶to的動詞不定式，置于某些動詞之后時，可以看作一個連接詞引導(dǎo)的賓語從句的簡略形式。
例句
a. I wonder who to invite（= who I should invite）.
b. Show us what to do（= what we can do）.
c. I don’t know whether to answer his letter（=whether I should answer his letter）.
類似的動詞還有：
ask consider decide discover explain
forget findout guess imagine know
learn observe remember see tell
teach think understand wonder
