It is very kind of you to help us. 注意：（1）其他系动词如look, appear等也可用于此句型。 （2）It is+ adj. of / for sb. to do sth. 结构中，若说明不定式动作对于执行者的影响，常在不定式前加for sb. 但是以形容词作表语来说明主语的行为品质时（如kind，good, nice，wise，clever，silly，wrong, right, foolish, stupid, careless, considerate, rude, naughty, polite, agreeable等），不定式前加of sb. （二）、不定式作宾语 1.动词+不定式。如： He managed to escape from the fire. I find it hard to get along with him.（it 作形式宾语） 注意：（1）只能以不定式作宾语，而不能以动名词作宾语的动词有： （“希望”干） wish, hope, expect, long, desire; （早“打算”） plan, mean, prepare, attempt, intend; （“同意”“否”）agree, consent, refuse, decline; （“寻”“问”看）seek, ask, beg; （“选”“定”了）choose, decide, determine, promise; （“尽”“自愿”）manage, volunteer, tend; （“称”“失败”）claim, fail; （“敢”“装蒜”）dare, pretend （2）可用于“动词+ it+形容词／名词+to do sth.” 结构中的动词有feel, find, make, think, believe, consider等。 （3）以动词不定式作宾语的形容词有happy，glad，pleased，sure，ready，anxious，eager，free，afraid，willing等。 （4）有些介词后也可以不定式作宾语，如介词but，about，except，save等。 2.动词+疑问词+to , “特殊疑问句+不定式”相当于名词，作宾语。如： I don’t know what to do next/ how to do it next. I can’t decide when to go there. （三）、不定式作补语 1.动词+宾语+不定式（to do ）。如： He warned me to be careful. I want you to speak to Tom. 注意：可以用动词不定式做宾补的动词有：ask, tell, order ,want ,get, would like, like, advise, invite, allow, help, wish, warn, expect, would prefer, encourage等。 2.在动词feel （一感），hear, l
