【知识梳理】一、疑问词加动词不定式(1)句法功能：“wh-词不定式”主要用作宾语或者宾语补足语，跟在动词decide,forget,advise,discuss,remember,understand,think,teach 等之后。疑问词分为疑问代词和疑问副词。常用的疑问代词有：what;which;who;whom;whose.疑问副词有：where,when,why;how e.g.:We must think what to do.I cant decide whom to invite.Daniel taught himself how to use a computer to draw.除用作宾语外，还可用作主语、表语等。e.g.:When to leave has not been decided.何时离开还没有决定。The question is how to find him.问题是如何找到他。(2)注意点：若动词不定式的动词为不及物动词，需要加上后面的介词。e.g.Daniel did not say who to talk to about this book.I dont know who to turn to for help when I have problems.原则上说，why 后不接不定式：误：Kitty explained why to be late for school.正：Kitty explained why she was late for school.不过若不定式不带 to，则可用 why。e.g.:Why not go there at once?Why argue with her?但这类结构通常只用于谈论现在和将来，不用于谈论过去。误：Why not clean the room yesterday?正：Why didnt you clean the room yesterday?(3)how 用于该结构的注意点：有些动词后接“how 不定式”作宾语时，how 可以省略：e.g.:Did you learn(how)to drive a car?你学过开车吗？但是，有些动词后面接“疑问词 how不定式”作宾语时，尽管其中的 how 在汉语中无需译出，但不能将 how 省略。e.g.:He knows how to play the piano.He showed her how to swim.(4)“疑问词十不定式”结构可以和复合句转换。e.g.:He asked where he would go shopping after supper.He asked where to go shopping after supper.二、be+adj.+enough+to do sth.表示“（某人、某物）足够做某事”例如：Im tall enough to reach the top of the tree.【拓展句型】be+adj.+enough+for sb.+to do sth.表示对某人来说“（某人、某物）足够做某事”1.enough 作形容词，意思是“足够的;充分的”。作定语置于被修饰的名词前后均可，前置时强调 enough，后置时强调被修饰词。如：Five men will be quite enough.I have enough books now.=I have books enough now.2.enough 作副词的意思是“十分地;充分地;足够地;充足地”，置于被修饰的形容词或副词之后，常与不定式或介词 for 连用，在句子中作状语，表示程度。如：Mum,I think Im well enough to get back to school.【拓展】enough 作感叹词时意思是“够了;停止;住手;不要再继续了”，用以表达不耐烦或恼怒。如：Youve been practicing the violin all afternoon.Enough!三、too.to.结构和用法(1).too.to.表示“太而不能”。too 的后面接形容词或副词的原级，to 的后面接动词原形。too.to.句型是简单句。如：He is too young to join the army.(2).too.to.结构表达肯定的意义.too 前面含有表示否定意义的词，如:not,never,nothing 等时，too.to.结构不表示否定的意义。如：It is never too old to learn.活到老，学到老。(要学永远都不迟。).too 后接表示感情的形容词，如 glad,pleased,happy,sad 等时，too.to.句型不再表示否定意义，而表示的是肯定意义。例如：He is too sad to hear the bad news.(2)too.to.结构与 enough.to.结构的相互转换 将 too.to.结构转换为 enough.to.结构时，要注意：.enough 前的形容词或副词应是 too 前面形容词或副词的反义词；.enough.to.句式须用否定式；如：She is too young to do the work.=She isnt old enough to do the work.四、It is+adj.+to do sth.做事怎么样 在此句型中 it 是形式主语，真正的主语是后面的不定式部分，由于主语较长，为了避免头重脚轻，用 it 做形式主语。有时 it 还可作为形式宾语，代替较长的宾语部分。如：It is great to be with you.I find it interesting to watch the action film.拓展句型：It is+n.+to do sth.如：It is a good idea to have a shower now.It is+adj.+for sb.+to do sth.对某人来说做事怎么样 此结构是一个陈述句,表示说话人对客观事件的决断,比较正式。这类形容词有 difficult,easy,hard,important,dangerous,(im)possible等。如：Its very dangerous for children to cross the busy street.Its difficult for us to finish the work.It is+adj.+of sb.+to do sth.对某人来说做事怎么样 此句型在英语中运用较为频繁,尤其在口语中。该句型通常表示说话人对客观事件的惊讶、兴奋、懊悔、难过等感叹情绪，其实相当于感叹句。如：Its very kind of you to help me.该句型中用作表语的形容词常见的有如下几类:(1)表示聪明或愚蠢的形容词,有 clever,wise,foolish,stupid,silly 等,如:Its silly of him to do such a thing.(2)表示正确或错误的形容词,有 right,wrong,correct,incorrect 等,如:It was right of her not to come here.(3)表示好坏等品性的形容词,此类词较多,有 good,nice,kind,sweet,friendly,lovely等,如:Its friendly of you to come and see me.(4)表示褒义或贬义色彩的形容词,有 brave,polite,careless,selfish 等,如:It was brave of you to manage to do it.【补充】of sb.的句型通常都可转换为不定式作状语的句子。Its very nice of you to offer me a seat.=You are nice to offer me a seat.十分感谢你给我让座。It is careless of him to lose so many things.=He is careless to lose so many things.他丢了这么多东西，真是太粗心了。【例题精讲】例 1:The purpose of the talk is to teach the students rules of eating.(对划线部分提问)_
