1、高考热点：动词不定式动词不定式的构成：to do解读：动词不定式虽然不能作谓语动词用，但仍留着动词的特征，它可以带有所需要的宾语或状语而构成动词不定式短语，如：to study hard, to play table tennis。动词不定式的形式变化 语态一般式完成式进行式完成进行式主 动to buildto have builtto be buildingto have been building 被 动to be builtto have been built动词不定式的基本用法：这里只学习不定式做主语，宾语，和状语的用法，它作定语和宾补的用法与分词一块学习。一 作主语句型： It is
2、/was +形容词/可数名词单数+ to do sth解读1：不定式作主语常见的是 it 作形式主语，放在句首，将真正的主语动词不定式（短语）放在句子后面。经典例句：1) Its easy to be wise after the event.2) It is easier to spend money than to make money.3) Its better to love someone you cant have than to have someone you cant love.4) It is not a good habit to stay up too late解读2：
3、此外形式主语it 不能用that、this 来替换。 这也是不定式作主语时的考点。出题句型是：_ is/was +形容词/可数名词单数+ to do 此句型特别重要，要牢记。判断下列句子读错，并说明理由：1 This is impossible for people to stare directly at the sun.2 Due to the refraction of light rays , this is impossible for the naked eye to determine the exact location of a star close to the horiz
4、on.解读3：it 作形式主语，不定式可以有自己的逻辑主语，通常用for + 名词（代词）或of + 名词（代词）放在不定式的前面。此时不定式的语态须看与逻辑主语的主被动关系。For与of的区别是初中内容。经典例题：1. Is _ possible to fly to the moon in a spaceship? A. this B. there C. that D. it2. The doctor thought _ would be good for you to have a holiday. (2010全国卷II 14).A. this B. that C. one D. it3.
5、 Its important for the figures _ regularly. （2011北京卷）A. to be updated B. to have been updated C. to updateD. to have updated二作宾语 1.直接作宾语句型：动词（vt）+ to do 解读：直接跟在一个及物动词后面作宾语。这时句子有以下两个特点：第一：句子的主语和不定式的逻辑主语是一致的，不定式的语态需看与句子主语的关系。第二：这时句子的谓语动词多是描写态度；不定式动作则说明行为。经典例句：1) Nobody wants to be laughed at.2) This c
6、ompany refused to cooperate with us.经典例题：1. I dont want _like I m speaking iii of anybody, but the manager s plan is unfair. (2005天津卷)A. to sound B. to be sounded C. sounding D. to have sounded2.

7、rking ; stopping B. to work ; stopping C. working ; to stopD. to work ; to stop3. As a young man , I hate_ in public. A. laughed at B. to be laughed at C. to laugh at D. laughing at 2. 句型：某些及物动词+连词+to do解读：在一些动词之后，可以在连接代词（what, who , which）或连接副词（how,when,where）及连词 whether 后面接一个带to 的动词不定式作宾语。常见的动词有：a
8、sk, decide, explain, forget, find out , guess, imagine , know, wonder.经典例句：1) I wonder who to invite. 2) Show us what to do .3) I dont know whether to answer his letter.考点解读：不定式的语态：必须用主动形式，此时易误选为被动形式。当连接词为代词时，不定式为及物动词，且其后不加宾语。经典例题：1. Theres so much delicious food! I cant decided_. A . what to eat B.
9、 when to eat C. how to eat D. where to eat2. Can you tell me _ on the Internet? A. how to search B. how search C. where can I search D. when can I search 3. He told us whether _ a picnic was still under discussion. (2009四川卷)A. to have B. having C. have D. had3不定式作宾语后置：如果不定式（宾语）后面有宾语补足语，则用it作形式宾语，真正的
10、宾语（不定式）后置，放在宾语补足语后面，构成句型“动词+ it +宾补（名词或形容词）+宾语to do ”。 经典例句：I think it hard to answer the question in one go. 我觉得很难一下子回答这个问题。He feels it challenging to be a marketing supervisor .经典例题：1. Using many symbols makesto put a large amount of information on a single map.A. possible B. it is possible C. it

(2010辽宁卷33) A. so B. much C. that D. it6. The two girls are so alike that strangers find _ difficult to t
13、ell one from the other. （2011山东卷）A. it B. them C. her D. that7. New technologies have made _ possible to turn out new products faster and at a lower cost. 【2012四川】A. that B. this C. one D. it 三. 状语构成以下几种句型句型1 ：形容词+to do （语言山表述为：形容词后面的动词不定式）解读1：该形容词为表示动作特点的形容词时，一般做两种成分：表语和宾补 当该形容词作表语时，句子主语和不定式动词可构成逻辑
14、上的动宾关系。 当该形容词作宾补时，句子宾语和不定式动词可构成逻辑上的动宾关系。经典例句：1) She is very nice to talk to .2) Mary is easy to get on with.3) I find English difficult to speak. 4) I find Football very interesting to watch. 此句型三大考点不定式动词一般不用被动形式：（最容易出错）不定式后不能再加宾语：不定式动词所带的介词不能省略：经典例题：1. Tom asked the candy makers if they could make the chocolate easier _ into small pieces. （2011安徽卷）A. break B. breaking C. broken D. to break2. This machine is very e
