一. 不定式在句中的功能做主语:那样做是很幼稚的.T 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。Ex. It is nt easy t learn English well.
做宾语她喜欢谈论这件事情。Ex. She lves t talk abut the matter.他希望不久能找到工作.He hpes t find a jb sn.他答应不把这事告诉任何人．He prmised nt t tell anyne abut it.
常接不定式做宾语的动词有： affrd, agree, aim, arrange, ask, attempt, begin, bther, care, chse, cntinue, dare, decide, demand, expect, fail, hate, hpe, learn, lng, manage, mean, need, ffer, plan, prefer, prepare, prmise, prve, refuse, want, wish等
1. 作定语的不定式如果是不及物动词，或者不定式所修饰的名词或代词是不定式动作的地点工具等，不定式后面须有相应的介词。 He is lking fr a rm t live in.
2. 不定式所修饰的名词如果是time, place或way，不定式后面的介词习惯上要省去。 He had n mney and n place t live.
3. smething, anything, nthing, everything等复合不定代词常用不定式做后置定语。
Have yu anything t send? 你有什么东西要寄吗？（不定式t send的动作执行者是yu）2) Have yu anything t be sent? 你有什么要（我或别人）寄的东西吗？（不定式t be sent的动作执行者是已被省略的me或smene else）
1. 不定式有时和连接代词/副词构成宾语. 你记得哪一条路到哪儿吗？ D yu remember which way t get there? 下一步干什么你决定了吗? Have yu decided what t d next? 我来问他怎么样开这机器. I’ll ask him hw t perate the machine.
2. 有时不定式由whether引起. I didn’t knw whether t laugh r cry abut it.3. feel, find, judge, make, think, believe, cnsider 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 t wrk with him.
做表语不定式可用作表语,说明主语的具体内容.My wrk is t clean the rm every day.我的梦想是成为一名医生.His dream is t be a dctr. 我的工作是帮助病人。My jb is t help the patient
My jb t________________.Yur task t_____________ .

(2). 不定式是t be 结构, be 不可省.

不定式与疑问词wh,which, when, hw, what等连用，在句中起名词作用，可充当主语、表语、宾语等。
