9、号中的中文提示、英文释义或句意，写出句中所缺单词，使句子通顺。1.Miss Wu is always patient enough to spend her time _(解释)to the students after class.2.The more books you read,the richer _ you will get.3.Take my advice and you will _(prevent something bad from happening)causing problems.4.-How was your last trip to Hainan?-It was _

10、(wonderful,amazing).I enjoyed myself.5.Im strongly _ smoking because its harmful to our health.答案：explaining/knowledge/avoid/fantastic/against 知识点二 Grammar 【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：wha

11、t;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

12、。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

13、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.

14、(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

15、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：Youv

16、e 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

17、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+a

18、dj.+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

19、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

20、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 an

21、d 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

22、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)_ the _ of the talk?例 2:He also knew the truth.(改为否定句)He _ know the truth,_.例 3:The box isnt light enough for him to carry.(改为同义句)The box is _ _ for him to carry.例 4:Hes just back home,_ _?(改为反义疑问句)例 5:
