期末冲刺03核心语法精讲练（二） 小贴士 疑问词+动词不定式 “疑问词＋动词不定式”结构相当于一个名词短语，可以作动词的宾语。疑问词包括疑问代词what、which、who和是问副词how、when、where等。 通常和“疑问词＋动词不定式”结构连用的动词及动词短语有：know、learn、see、hear、ask、tell、advise、decide、explain、find out、forget、remember、think、understand、wonder等。 这种结构可以在句子中作主语，宾语和表语。 How to do it is a question.‌（作主语） ‌I really don't know what to write about.‌（作动词宾语） ‌The question is where to put it.‌（作表语） 此外，这种结构还可以改写成由疑问词引导的从句，从句的成分不变。例如： ‌How we should do it is a question.‌（改写为主语） ‌I really don't know what I should write about.‌（改写为动词宾语） ‌The question is where we should put it.‌（改写为表语）‌ 有些动词，如advise、ask、show、teach、tell等，其后可以接双宾语。如： Please tell me how to get there.请告诉我怎么去那儿。 Sandy showed Mille how to start the online tour.桑地给米莉演示了如何开始这个在线旅游。 有些疑问词，如what、which、whose、how many、how much等，其后可以先接一个名词，再接动词不定式。如： She wondered how many subjects to choose. 她不知道该选几门学科。 在“疑问词＋动词不定式”结构前，有时也可以是如sure、clear等的形容词。如：I am not sure which way to take.我不确定走哪条路。 “疑问词＋动词不定式”结构可以改写成由该疑问词引导的从句。如： I do not know what to do.我不知道该做什么。 =I do not know what I should do. 注意：所 有 疑问词中，只有why不可以与动词不定式还用。 must／have to的用法 must表示主观的义务和必要，主要用于肯定句和疑问句，意思是“必须，得，要”。如：You must finish your homework today.你今天必须完成家庭作业。 must的否定形式must not表示禁止，意思是“不能，不许”。如： You must not smoke here.你不能在这里抽烟。 have to表示一种客观的需要，意思是“不得不”。have to有人称和数的变化。如： It ls getting dark. He have to go home now.天快黑了。他现在得回家了。 Mum ls out， so I have to look after the chop，妈妈出去了，因此我不得不照看商店。 ·have to的否定形式是do not have to。如： They do not have to buy a computer at the moment，他们目前没有必要买电脑。 He does not have to go， 他不必走。 enough to的用法 我们可以用“to be＋adjective＋enough＋to do”的结构来描述一个人的品质和能力。"enough...to" 是一个常用的句型，表示某个条件或程度已经达到了某种要求或目标。 结构： "enough" 是副词，意为“足够的”；"to" 是介词，后面接一个动词原形。 用法： "enough...to" 句型用于表达一个主体已经达到了某个程度或条件，足够去实现某种行动或产生某种效果。 例： He is old enough to drive a car.（他已经足够年长可以开车。） She is brave enough to face her fears.（她足够勇敢，能够面对自己的恐惧。） 注意事项： "enough" 通常位于形容词或副词之前，但在名词之后。例如："old enough," "smart enough," "strong enough," "money enough"。 "enough" 可以放在句子的不同位置，以强调不同的信息。 例如："I have enough money to buy a car"（我有足够的钱买车）可以改写为 "Enough money, I have, to buy a car"（足够的钱，我有，买车）。 "enough" 后面可以接动词原形，表示足够去做某事。 例如："He is strong enough to carry the heavy box"（他足够强壮，能够搬运重箱子）。 too...to的用法 一、too…to…结构的基本形式为“too+形容词或副词+to+动词原形”,其意为“太……以至于不能……”。 eg： 1.He is too shy to speak to her. 他太害羞，不敢同她讲话。 2.It’s too cheap to be good. 这东西太便宜，好不了(即便宜无好货)。 3.He is too young to know right from wrong. 他太小，还分不清是非。 二、动词不定式所表示的动作的执行者与整个句子的主语不指同一人或物时，需要在动词不定式前加上一个逻辑主语(常用for sb.)。 eg： 1.It’s too expensive for her to buy. 太贵了，她买不起。 2.The box is too heavy for the boy to carry. 这个箱子太重，这男孩提不起。 3.The print is too small for me to read without glasses. 印刷字体太小，我不戴眼镜就看不清。 三、将too...to...结构转换为so... that... 结构时，要注意： 1.so... that... 结构是复合句,so 的后面接形容词或副词的原级， that的后面接从句。 2. that后面的从句要用否定形式。 eg： 1)The box is too heavy for me to carry. → The box is so heavy that I can’t carry it. → It is such a heavy box that I can’t carry it. 2)The child is too young to dress himself. → The child is so young that he can’t dress himself. → He is such a young child that he can’t dress himself. 四、将too...to...结构转换为enough... to... 结构时，要注意： 1.enough 前的形容词或副词应是too前面形容词或副词的反义词； 2.enough... to... 句式须用否定式； 3.too... to...结构有逻辑主语时，enough... to... 结构也要加上逻辑 主语。 eg： 1)She is too young to do the work. = She isn't old enough to do the work. 　 2)The problem is too hard for him to work out. = The problem isn't easy enough for him to work out. “It is + adjective(for⋯/of⋯)+to do sth.''句型 ‌It is + adjective (for/of) 句型‌是一种常见的英语句型，主要用于描述做某事对某人来说如何。在这个句型中，‌it‌作为形式主语，真正的主语是后面的不定式短语。形容词用来描述事物的特征或行为者的性格、品质。 用法区别 ‌用for的情况‌：当形容词描述的是事情的特征时，使用‌for‌。例如： ‌It is important for us to study English.‌（学习英语对我们来说很重要） ‌It is difficult for her to solve this problem.‌（对她来说解决这个问题很难） ‌用of的情况‌：当形容词描述的是人的性格或品质时，使用‌of‌。例如： ‌It is kind of you to help me.‌（你帮助我真是太善良了） ‌It is clever of you to answer the question so quickly.‌（你快速回答问题真是太聪明了） 常见搭配的形容词 ‌用for时‌：easy, hard, difficult, important, necessary, dangerous等。 ‌用of时‌：kind, friendly, clever, rude, silly, foolish等。 注意： "It is+ adjective +Of somebody＋ to do something”句型中，of后的宾语与动词不定式之间存在逻辑上的主谓关系，一股都可以转换成一个以of后的宾语为主语的句子。如：It is foolish of them to do so.他们这样做真是愚蠢。= They are foolish to do so. 实战训练 一、单项选择 1．—Have you decided ________, lady?    —Sorry, I haven’t.

So she didn’t know ________ about the trouble. A．who to talk B．who to say C．who to talk to D．what to talk 【答案】C 【详解】句意：露西几乎没有亲密的朋友，所以她不知道该和谁谈谈这个问题。 考查固定结构“疑问词+动词不定式”。what to talk结构错误，what是talk的宾语，需用介词about连接；who to say搭配不当，say需接说的内容，和what搭配；who to talk to与谁交谈；who to talk结构错误，who是talk的宾语，需用介词to连接。根据句意结构和语境可知，露西缺少与之谈论的人，所以疑问词为who，后面动词部分为talk to。故选C。 6．April 23rd is World Book and Copyright Day (世界读书日) .

They have to keep working till they finish it. A．having a rest B．not to have a rest C．to have a rest D．they have a rest 【答案】C 【详解】句意：工人们太忙了，无法休息。他们不得不一直工作直到完成任务。 考查非谓语动词。too...to...“太……而不能……”，固定搭配，所以这里应用动词不定式结构，排除A和D；而“not to have a rest”不符合“too...to...”的结构，排除B。故选C。 19．— Let me look at the main points in your notebook, Lily. — Sorry, I was too slow to _______.

A．when to say B．what to say C．how to say D．what to say it 【答案】B 【详解】句意：其中一个矮个子男人开始跟我说话，但我不知道说什么。 考查疑问词加不定式的用法。when to say何时说；what to say说什么；how to say如何说；what to say it错误表达。根据“One of these small men began talking to me, but I didn’t know...”可知，空处指我不知道“说什么”，需what to say，在句中作宾语。故选B。 21．He drove the car too ________ to find the right direction to get home.

A．for; to support B．of; to support C．for; support D．of; supporting 【答案】A 【详解】句意：对于我们来讲，支持慈善事业是有意义的。 考查介词和非谓语动词。It is+adj.+for sb. to do sth.“对于某事来讲，做某事是……的。”句型中形容词通常用于修饰“做某事”。 It is+adj.+of sb. to do sth.“某人做某事是……”，形容词通常表示人的品格。support是动词，意为“支持”。这里表示“支持慈善事业是有意义的”。故第一空填for；第二空用动词不定式作真正的主语。故选A。 29．— Did you feel ________was selfish of Jack to hide the comic books? — Yes.

A．that; of B．that; for C．it; of D．it; for 【答案】D 【详解】句意：—— 你觉得Jack把漫画书藏起来很自私吗？—— 是的。对一个男孩来说学会分享是很重要的。 考查it的用法和介词。 根据“It is adj. to do sth.”可知， 第一空it符合句意；根据“important”可知，修饰的是“learn to share”这件事，因此用介词for“对……来说”。故选D。 30．It’s very________you to make the same mistake again. A．careful of B．careful for C．careless of D．careless for 【答案】C 【详解】句意：你再犯同样的错误真是太粗心了。 考查固定句型。careless粗心的；careful细心的，根据后面的make the same mistake again可知，应该是粗心的，排除A和B，由固定句型it’s +形容词+of/for sb to do sth“某人做某事……”，当形容词是可修饰人的形容词，即sb和adj.有主系表关系时，sb前用of；当形容词是不可以修饰人的形容词，即sb和adj.没有主系表关系时，sb前用for，由careless是修饰人的形容词，所以用of，排除D，故选C。 31．—I think is necessary to help the people in need. —Yes, I agree with you. A．it B．this C．that D．what 【答案】A 【详解】句意：——我认为有必要帮助有需要的人。——是的，我同意你的说法。 考查代词辨析。it它，可作形式主语； this这个；that那个； what什么。固定句型It is+形容词+to do sth.做某事是……；这里it是形式主语，真正的主语是动词不定式“to help the people in need”。根据题意，故选A。 32．─What do you think of tomorrow's football match？ ─_________ difficult for us _________ the match.

A．of, to raise B．for, to raise C．for, to donate D．of, to donate 【答案】D 【详解】句意：他把如此多的钱捐给贫困地区的孩子们真是非常慷慨的。 It’s+adj.+of sb. to do sth.与It’s+adj.+for sb. to do sth的区别在于，如果形容词是修饰人的，如友好的，大方的等就用of；如果形容词是描写事物性质的，如事情的难易程度、重要性等就用for,本题中generous慷慨的，是修饰人的形容词，所以应该用of；又因为“给某人捐献某物”为donate sth. to sb.，故选D。 【点睛】1. It is +adj.+for sb.+to do sth.对于某人来说做某事是怎么样的。此句型中，“for me”表示“对于某人来说”。注意be后面一定是描写事物性质的形容词。例如important(重要的)，necessary(必要的)，difficult(困难的)，easy(容易的)，hard(艰难的)，dangerous(危险的)，safe(安全的)，useful(有益的)，pleasant(舒适的)，interesting(有趣的)，impossible(不可能的)，right(正确的)，convenient（方便的）等等。 2. It is +adj.+of sb.+to do sth.表示某人做某事真是太怎么样了。此句型中的形容词一定是描述人的品质的。例如good(好的)，kind(友善的)，nice(友好的)，polite(有礼貌的)，clever(聪明的)，foolish(愚蠢的)，stupid（愚蠢的），lazy(懒惰的)，right(正直的)，careful(细心的)，careless(粗心的)，brave（勇敢的），cruel（残酷的）， honest（诚实的），naughty（淘气的），rude（粗鲁的）等。 二、单词拼写 34．It’s necessary for volunteers (receive) training before doing the tasks. 【答案】to receive 【详解】句意：志愿者们在进行任务之前让接受训练是有必要的。根据句意和句子结构可知，本题考查It is + 形容词 + (for sb) to do sth.“做某事对某人来说是……的”，It是形式主语，真正的主语是后面的动词不定式短语。所以，此空须填receive的动词不定式形式to receive。故填to receive。 35．—Let’s go to the cinema. (late) —No, it’s to the cinema. 【答案】too late to go 【详解】句意：——我们去看电影吧。——不，现在去看电影太晚了。根据“Let’s go to the cinema.”以及“No”并结合备选词可知，此处是指太晚了不能去看电影，too…to…“太……以至于不能……”，go“去”。故填too late to go。 36．It is important for us (eat) vegetables. 【答案】to eat 【详解】句意：吃蔬菜对我们来说很重要。根据“It is important for us…vegetables.”，结合备选词可知，此处考查固定句型：it+be+adj.+for sb.+to do sth.“对于某人来说做某事是……的。”，所以此处应该填入to eat，不定式，作真正主语。故填to eat。 37．It’s pleasant (walk) in the forest. 【答案】to walk 【详解】句意：在森林里行走是令人愉快的。根据It’s pleasant以及walk可知，符合结构：it is+形容词+to do sth.。意为“做某事很……”，该空应填写to do不定式，to walk符合题意。it是形式主语，真正的主语是不定式to walk。故填to walk。 38．It’s proper for us (shake) hands with others when we are first introduced to each other. 【答案】to shake 【详解】句意：当我们第一次被介绍给对方时，我们与他人握手是正确的。shake hands“握手”，句子是结构“it is adj. for sb. to do sth.”，意为“做某事对某人来说是……的”，动词不定式作真正的主语。故填to shake。 39．—Why don’t we sit in the garden?

The Maths problem isn’t for me work out. 【答案】 easy enough to 【详解】句意：这道数学题对我来说太难了。too ... to do sth.“太……而不能做某事”，改写后的句子空前有否定词isn’t，形容词用difficult的反义词easy表示“容易的”，此处表示不够容易，enough后置，修饰形容词，其后用动词不定式。故填easy；enough；to。 59．The book is so interesting that everybody likes to read it. The book is everybody to read. 【答案】 interesting enough for 【详解】句意：这本书如此的有趣以致于每个人都喜欢读它。根据“so interesting that”可知，原句中使用的是so...that引导结果状语从句，其同义句可以使用“adj.+enough for sb. to do sth.”这一句型。故填interesting；enough；for。 60．Michael’s grandfather is too old to drive a car.
