To know oneself is difficult. 但在很多情况下，为了保持句子平衡，通常用it作为形式主语，而把不定式移到谓语之后， e.g.: It is difficult to know oneself. It is important to learn English. 2. 作表语. 不定式作表语说明主语的具体内容或表示目的。 e.g.: His wish is to become an engineer. To live is to do something worthwhile. 3.作宾语. 作动词的宾语，即动词+to do sth. 常见的要加不定式作宾语的动词有：decide/ determine, learn, want, expect/ hope/ wish, refuse, manage, pretend, offer, promise, choose, plan, agree, ask/ beg, afford, prefer, require, enable, need, order… e.g.: He agreed to meet here but so far she hasn’t turned up yet. He pretended not to see me when I passed by. 在find, make, think, consider等动词后，如果宾语带有宾语补足语时,常用it作形式宾语，而把真正的宾语放在宾语补足语后. e.g.: I find it interesting to study English. I think it impossible to work out the problem. 4、作宾语补足语，即Ｖ＋sb. (not) to do sth.如动词advise, allow, ask, cause, challenge, command, consider, enable, encourage, forbid, force, inform, invite, persuade, tell, send, urge, want,warn…. Eg. :I want you to speak to Tom. Ask him not to make noise. (1)在感官动词以及使役动词（let, have, make）后作宾语补足语，不定式都不带to.变为被动语态时，原不带to的不定式要变成带to的不定式. “一感(feel)二听 (hear, listen to )三让(let, have, make )四观看(see, observe, watch, look at)” e.g.: I often hear him sing the song. Did you see him go out? The boss made the employees work ten hours a day. The employees we
