托福备考中，词汇是一个很终于要的环节，下面我们就讲一下不定式作宾语、主语或表语，分别有哪些注意点。

　　1. 作宾语：不定式多接在谓语动词后作宾语

　　如：He decided to put in a good word for me at the meeting.

　　I didn’t expect to hear from you so soon.

　　常用的可接不定式宾语的动词有：decide, expect, determine, offer, forget, remember, want, prefer, wish, hope, continue, begin, attempt, agree, etc.

　　例：Human beings are social animals who usually prefer not to live in physical or psychological isolation.

　　2. 作主语：不定式短语可作主语

　　如：To see is to believe (百闻不如一见)

　　To work hard should be your major concern.

　　注意：由于英文不习惯句子主语过长，不定式主语常被形式主语it所代替(详见第十七章)

　　例如上面第二句可以变为： It should be your major concern to work hard.

　　又如： It is very nice of you to help me.

　　It is hard for you to carry this heavy box.
