He always has a lot of meetings to attend. 不定式to attend 和名词meetings 形成动宾关系The next train to arrive was from Seattle. To arrive 和train形成主谓关系Do you have anything interesting to read?如果作定语用的不定式是不及物动词，就要加上介词，使被修饰的这个词成为这个介词的逻辑宾语。
动词不定式用法全解(含测试题及答案)
动词不定式用法全解英语动词的非谓语形式为三种：动词不定式、动名词和分词。
非谓语动词没有人称和数的变化。
动词不定式是一种非谓语动词形式，其结构为“to＋动词原形”，其中to不是介词，而是动词不定式的符号，称为小品词，动词不定式没有人称和数的变化。
动词不定式和其后面的名词等构成不定式短语，在句子中可以用作主语、表语、宾语、补足语、定语、状语等。
动词不定式的形式：第一部分动词不定式的时态一、动词不定式的时态：动词不定式不能在句中作谓语，尽管它本身有时态的变化，但是却不能靠自身的变化形式表示动作发生的具体时间。
动词不定式发生的时间，一般只能根据谓语动词的时间，产生相对的先后时间关系。
1．不定式的一般式，表示不定式的动作与谓语动词动作几乎同时发生，或在谓语动作之后发生，或者不强调不定式动作的时间性。
但不定式表原因时，往往先于谓语动作之前发生。
如：The news will not fail to surprise him.这个消息将不会不使他大吃一惊的。
（不定式动作在将来和谓语动作同时发生）I helped to repair the car.我帮助修理汽车。
（不定式动作在过去与谓语动作同时发生）He didn't know where to go.他不知道该去哪儿。
（不定式稍晚于谓语动作）Tell your brother not to come tomorrow.告诉你哥哥明天不要来。
（不定式晚于谓语动作）判断：He decided to sell his car.I tried to go to school in time.I hope to see you soon不定式表示谓语动作的原因时，往往发生在谓语动作之前。
如：I am very happy to see you here.She seemed surprised to meet us.（先是遇见我们，她然后很吃惊）2．不定式的完成式，通常表示动作发生在谓语动词之前。

(完整版)动词不定式用法
动词不定式用法不定式是动词的一种非限定式，它是不受主语的单复数、人称、时态、语态等的限定及影响的一种动词形式。
一、动词不定式的基本结构动词不定式的基本形式为：to+动词原形，有时可不带to。
不定式的否定形式是：not to+动词原形。
在句中除不能作谓语外，其他成分都可作。
如：主语、表语、宾语、宾语补足语、定语和状语等。
注意：不定式之前的to（又称为小品词）与介词to的功能不同。
介词to之后要接名词或代词的宾格，或相当于名词的短语作它的宾语；而不定式符号to的后面需要跟动词原形。
speak to him (to 是介词) 对他讲话to speak English (to 是不定式的小品词) 讲英语二、动词不定式的用法不定式在句中有各种作用，一般可归类为三种基本用法：作名词，作形容词，作副词。
(一) 不定式作名词的用法不定式起名词作用，在句子中担当主语、表语、宾语和宾语补足语。
⒈作主语名词用法的不定式和名词一样，可担任句子的主语。
To grow more trees here is very important.(=It is very important to grow more trees here.) 在这里多种些树是非常重要的。
To hear your voice is so nice.(=It is so nice to hear your voice.) 听到你的声音真高兴。
To speak English well is not easy for me.(=It is not easy for me to speak English.) 把英语说好对我来说并不容易。
To walk to school takes me twenty minutes.(=It takes me twenty minutes to walk to school.) 步行到学校我要花20分钟。
的句型中，it是形式主语，真正的主语是不定式；使用这种注意：在It is… to…”结构，可以避免句子的头重脚轻。

动词不定式练习题及讲解
动词不定式用法要点讲解一、作主语动词不定式作主语时，句子的谓语动词常用单数，其位置有以下两种：(1)把不定式置于句首。
如：To get there by bike will take us half an hour.(2)用it作形式主语，把真正的主语不定式置于句后，常用于下列句式中。
如：①It＋be＋名词＋to doIt's our duty to take good care of the old.②It takes sb+some time+to doHow long did it take you to finish the work?③It＋be＋形容词＋for sb＋to doIt is difficult for us to finish writing the composition a quarter of an hour.④It＋be＋形容词＋of sb＋to doIt is stupid of you to write down everything the teacher says.⑤It seems(appears)＋形容词＋to doIt seemed impossible to save money.二、作宾语⒈不定式作宾语①以下动词后，只能跟不定式作宾语。
如：agree,ask,aim,arrange,choose,decide,demand,expect,fail ,help,hope,lean,longmanage,offer,plan,prepare,pretend,promise,refuse,wish等，这些词大部分可接th at引导的从句。
如：When our visit to the farm was over, we expected to start back on foot.When our visit to the farm was over, we expected that we would start back on foot.②当复合宾语中的宾语是不定式时，先用形式宾语it代替不定式，把不定式置于补语之后，即：主语＋动词＋it＋补语＋to do句式。

Grammar Presentation---动词不定式一、不定式的句法功能●不定式作主语➢To learn a foreign language is not easy.学习外语不是一件容易的事。
◎不定式短语作主语时，常用it作形式主语来代替它的位置，而将真正的主语（不定式短语）移到谓语之后➢It’s a great honor to be invited to Mary’s birthday party.很荣幸被邀请参加玛丽的生日聚会。
●不定式作宾语◎作动词宾语◇下列动词常接不定式作宾语，如：agree, arrange, ask, beg, choose, dare, decide, demand,expect, fail, fear, hope, manage, offer, plan, prepare, pretend, promise, ➢They hope to find new resources for mankind.他们希望为人类找到新资源。
◇如果不定式作宾语且有自己的补语，常用“it”作形式宾语，而把真正的宾语放在后面。
下列动词常用it作形式宾语，如：believe, consider, feel, find, know, make ➢I know it impossible to finish so much homework in one day.我知道在一天中完成这么多的作业是不可能的。
●不定式作表语◎不定式作表语时，一般紧跟在系动词后，说明主语的内容➢The first step is to check the victim’s breathing.第一步是检查受害人的呼吸。
●不定式作补语➢I’d like the problem to be discussed at the next meeting.我希望这个问题在下一次会上讨论。
●不定式作定语➢The students have a lot of homework to do every day.学生们每天都有很多家庭作业要做。
●不定式作状语不定式可以作原因状语、结果状语、目的状语以及方式状语不定式在下列句式中作目的状语：so as to do, in order to do➢In order to ensure your hair looks its best, pay attention to what you eat.为了保证你的头发是最佳状态，请注意你的饮食。
二：不定式考点归纳：考点1：不定式的时态和语态：1.---Is Bob still performing?---I’m afraid not. He is said ____the stage already as he has become an official.A. to have leftB. to leaveC. to have been leftD. to be left2.The news reporters hurried to the airport, only ____ the film stars had left.A. to tellB. to be toldC. tellingD. told1．A. 根据句子的意思“据说他已经离开了舞台”，要用不定式的完成式的主动形式。
2．B. 用动词的不定式的被动形式表示结果状语。
考点2：不定式的功能：不定式具有名词的特征，可以作主语或宾语（例5），具有形容词的特征，可以作表语、定语或补足语（例4）；具有副词的特征，在句子中可以作状语（例3）。
3.It was unbelievable that the fans waited outside the gym for three hours just ____ a look at thesports stars.（2005 上海卷）A. hadB. havingC. to haveD. have4.I don’t want _____ like I’m speaking ill of anybody, but the manager’s plan is unfair.A. to soundB. to be soundedC. soundingD. to have sounded5.In fact ____ is a hard job for the police to keep order in an important football match.A. thisB. thatC. thereD. it3．C.本题考查不定式作目的状语。
“体育球迷们等在体育场外三个小时，目的仅仅是为了看一眼这些体育明星”。
4．A. want后面要选用不定式形式，sound是连系动词，不能用被动语态。
5．D.句子的真正主语是不定式短语to keep order in an important football match形式主语。
考点3：不定式的省略：分为两种：一种是不定式符号“”后面省略实义动词的形式（见考例6）；另一种则是对不定式符号“”的省略（见例7）。
6.The boy wanted to ride his bicycle in the street but his mother told him_______.(NMET2005)A. not toB. not to doC. not do itD. do not7.Paul doesn’t have to be made ____. He always works hard. (NMET2005)A. learnB. to learnC. learnedD. learning6．A. tell sb. to do sth. 的意思是“告诉某人做某事”，其否定形式是在to前面加not。
英语中，为了避免重复，常用省略形式，因此这个句子省略了do it。
选项B如果加上it，也是正确的。
7、B．make, let, have, hear, see, feel, watch, notice等动词，后面接不定式作宾补语时，常省略不定式to。
但是，当这类动词用于被动结构作主语补足语时，动词不定式必须带to。
考点4：不定式的否定形式动词不定式的否定形式是在不定式符号“”前面直接加上，有进为了强调也可以用否定词来否定（见考例8、9）8.The purpose of new technologies is to make life easier, _____ it more difficult.(NMET1999)A. not makeB. not to makeC. not makingD. do not make9.The teacher asked us ____ so much noise.(2003北京卷)A. don’t makeB. not makeC. not makingD. not to make8、B．动词不定式to make life easier和not to make it more difficult都作is的表语。
做这类题目时，要比较非谓语动词的形式，前后要保持一致，后面不能省略to。
9、D．本题考查动词不定式的否定形式作宾语，句子的意思为：老师叫我们不要制造很大的噪音。
考点5：不定式的搭配形式：不定式常常独立存在的，如果强调其所表动作的时间、地点、内容、方式等时，可出现“疑问+不定式”的结构；强调动词不定式所表动作的使用工具、范围等时应使用“不定式+介词”的结构（见考例10）。
10.It is said in Australia there is more land than the government knows______.（NMET2002）A. it what to do withB. What to do it withC. what to do with itD. to do what with it10、本题考查“疑问+不定式”和动词作短语do with的用法。
根据本题的句意可以看出，由于know不可以直接跟动词不定式而排除D；“疑问+不定式”结构当然要把疑问词置于前面，从而排除A；what…do with…实际上是一个常用的短语，在短词中what作do的宾语，句中的it作介词with的宾语，故选C。
