To act like that is childish. 为避免句子出现 “头重脚轻”现象，常用it 做形式主语，将真正主语的不定式后置。 要学好英语不是那么容易的。 e.g. It is not easy to learn English well.;;常接不定式做宾语的动词有： afford, agree, aim, arrange, ask, attempt, begin, bother, care, choose, continue, dare, decide, demand, expect, fail, hate, hope, learn, long, manage, mean, need, offer, plan, prefer, prepare, promise, prove, refuse, want, wish等.;;2) 有时不定式由whether引起。 I didn’t know whether to laugh or cry about it. 3) feel, find, judge, make, think, believe, consider 等动词后如果是不定式做宾语， 补语是形容词(间或是名词)，常用it作形 式宾语，把不定式后移。 I find it difficult to work with him.;;;在主动结构中, 下列动词后作宾补的动词不定式应 省略to: “五看”(see, watch, notice, observe, look at) “三使”(make, let, have) “两听”(hear, listen to) “一感觉”(feel)。 e.g. Who made him work all night long? The policeman saw a child play in the street. Don’t make the children do such heavy work. Shall I have him come here? 但是, 改为被动结构后, 应补出省略的to。 e.g. He was seen to break the window.;The policeman saw a child play in the street. A child was seen to play in the street by the policeman.;4. 作表语 不定式可用作表语，说明主语的具体内容。 My work is to clean the room every day. 我的梦想是成为一名医生。 His dream is to be a doctor. 我的工作是帮助病人。 My job is to help the patient ;5. 作定语 不定式放在被修饰的名词、代词后面，往往 表示未发生的动
