五、不定式结构作状语
不定式结构可以作状语，修饰动词、形容词、副词等，表示目 的、原因、结果、条件等。 1．表示目的： They ran over to welcome the delegates. He bought a bicycle to go to town more quickly. He went home to see his mother. 注①：不定式结构表示目的时，通常句子的主语就是它的逻辑主语 (参见以上三句)，但也有例外的情况，例如： I stopped for him to speak to me. He opened the door for the children to come in. He brought a porter to carry the boxes / bags. They sent a man to mend the window. He stood up to be seen better.
பைடு நூலகம்
四、不定式结构作定语 1．不定式作定语通常只能放在被修饰的名词之后，如： It’s time to go to bed. He is not a man to bow before difficulties. Have you anything to declare? She usually has a lot of meetings to attend in the evening. I want to get something to read during the vocation. 2．能带不定式结构作宾语的动词，转化成名词时往往也能带不定 式结构作定语，如： I don’t wish to quarrel with you. →I have no wish to quarrel with you. They will attempt to cross the river tonight. → They will make another attempt to cross the river tonight. She promised not to do that again. → She made a promise not to do that again.

动词不定式知识点详解(初中英语专项复习)3
动词不定式知识点详解（初中英语专项复习）辨析谓语动词VS非谓语动词1.谓语动词：顾名思义，在句中充当谓语，形式与句子时态相关。
例如：一般现在时态，谓语动词有原形和三单两种形式。
He gets up at 5:00 o’clock every day.一般过去时态，谓语动词形式为过去式。
We went to Hong Kong last summer.2.非谓语动词：是相对于谓语动词而言的，非谓语动词不担任谓语成分,且具有其他词类特征的动词形式，即不定式，动名词和分词（现在分词和过去分词）。
例如：My teacher told me not to make noise in class.Watching movies help me learn English.The man standing under the tree is my father.I had my hair cut yesterday.非谓语动词不定式1.动词不定式的结构：肯定形式：to +动词原形。
否定形式：not+ to +动词原形。
2.动词不定式的用法（1）作主语例句：To learn English is important.=It is important to learn English.To walk to school takes me 20 minutes.=It takes me 20 minutes to walk to school.注意：在It is… to…”的句型中，it是形式主语，真正的主语是不定式,使用这种结构,可以避免句子的头重脚轻。
通常不定式被视为第三人称单数，所以谓语动词用单数。
It作形式主语常见结构：▲ “It is + adj./n+(for sb.) to do sth .例：It is important for us to keep a balanced diet.▲ It is + adj.+of sb+ to do sth(在kind，good, nice, clever等表示人的品质的形容词后,介词要用of)例：It is silly of you to lend him money again.▲ It takes sb. +一段时间+ to do sth.例：It takes me three hours to finish the task.作表语例句：My dream is to be a teacher.作宾语（动词+to do）例句：I want to play with you.I hope to travel around the world.常见动词：want, wish, hope, like, begin, start, help, agree, refuse, promise, learn, forget, know, need, try等。

动词不定式复习语法复习：动词不定式动词不定式(to do)是初中英语课的一个重点，也是中考要考查的一个项目。
动词不定式属于非谓语动词的一种形式，很多同学经常把它和谓语动词混在一起，掌握起来有困难。
下面我们对动词不定式的用法做简单归纳，帮助同学们记忆：一、动词不定式在句子中不能充当谓语，没有人称和数的变化。
二、动词不定式是由“to+动词原形”构成(有时可以不带to)。
动词不定式的否定形式是“not+动词不定式”(not不与助动词连用)。
三、动词不定式短语具有名词、形容词和副词等的功能，可在句中用做多种句子成分。
1、主语：常置于句末，而用it代替其做形式主语。
To go in for sports helps you stay fit.It is dangerous to swim in the deep sea on your own.注：此句式中不定式逻辑上的主语可由for或of引出，逻辑主语由of引出时，表语的形容词为kind, nice, good, polite, clever, foolish, right, wrong等表示评价的形容词。
例：It’s right of him to refuse the invitation. (him为逻辑主语)2、表语：Our duty is to protect the environment.3、动词宾语：此种情况可按固定搭配或句式去记。
例：Would you like to see my photos?Kevin planned to visit his uncle.和plan用法一样的词还有：start, want, agree, hope, begin, decide等。
I found it very difficult to get a job. (it为形式宾语)4、宾语补足语：(1) 在多数复合宾语及物动词后要带to。
例：I asked a friend to read it to me. (book4，L2)(2) 在表示感觉、致使等意义的动词(see, watch, hear, feel, notice, observe, make, let, have, help等) 后不带to。
例：They heard him sing a pop song in the meeting room.5、定语：动词不定式做定语放在所修饰的名词的后面。
例：I have something important to say.6、形容词补足语:在表示心理、感情、评价等的形容词后，对其进行补充说明。
例：We are very glad to meet you again.7、状语：表示目的、原因、程度等。
例：They brought in photos of their families for me to look at.8、“疑问词+不定式”用法：不定式前可带what, who, which, where, when, how等疑问词，这种不定式短语在句中多用做宾语。
例：He didn’t tell me where to go.不定式综合练习：一．用动词的适当形式填空（包括时态和动词的非谓语形式）1、Joe Hill wrote songs_______(keep) up the workers' struggle.2、His brother told me he enjoyed_______(play) football very much.3、Stop ______(talk), you will hear something strange.4、Don't make him_______(climb) the tree.5、This year they are going __________(put) up a new theatre (戏院).6、These books can't___ __(return) to you, because I __ _(not finish)_______(read) them.7、Father asked his son_______(not play) with fire.8、The students were asked __________(take) out a piece of paper and write down thesentences on the blackboard.9、After having a rest , he went on ______(do) his homework.10、It's time for you __________(empty) the dustbin.11、A lot of information __________(put) into the computer yesterday .12、It's important ___________(do) morning exercises every day.13、To a doctor the most important thing is_________(save) lives.14、The boss made us_________(work) more than ten hours a day.15、The professor had a strange way of________(make) his lessons lively and interesting.16、(put)_______on your coat and be careful ___________(not catch) a cold.17、I am sorry _______(keep) you________(wait) so long.18、How ________(get) to the science museum is a question.19、It takes me half an hour__________(go) to school on foot.20、She was never heard ___________(sing) so well before.21、She often does__________(shop) in the evening.22、They stopped________(listen) to her songs because they were fond of _______(sing).23、It's rather cold ,you'd better_________(not take) off your coat.24、It's kind of you_________(give) seat to the old man.25、May I use your dictionary for a minute?
