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 build to have built to be building to have been building ‎ 被 动 to be built to 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/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) It’s easy to be wise after the event.‎ 2) It is easier to spend money than to make money.‎ 3) It’s better to love someone you can’t have than to have someone you can’t love. ‎ 4) It is not a good habit to stay up too late 解读2： 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 horizon.‎ 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. it ‎2. 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. it ‎3.. It’s important for the figures _________ regularly. （2011北京卷）‎ ‎ A. to be updated B. to have been updated C. to update D. 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 company refused to cooperate with us.‎ 经典例题：‎ ‎1. I don't 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 sounded ‎2.

(2006北京卷)‎ ‎ A. working ; stopping B. to work ; stopping C. working ; to stop D. to work ; to stop ‎3. 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：ask, 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 don’t know whether to answer his letter.‎ 考点解读：‎ ‎①不定式的语态：必须用主动形式，此时易误选为被动形式。‎ ‎②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. There’s so much delicious food! I can’t decided________. ‎ A . what to eat B. when to eat C. how to eat D. where to eat ‎2. 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. had ‎3．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.
