1、非谓语动词语法一、非谓语动词的概念动词的基本用法是作谓语。当句中已经有了谓语动词了，要选或要填的动词就只能用非谓语形式了。非谓语形式有三种：1、动词不定式：to do 2、动词的ing : doing 3、动词的过去分词：done二、三种形式的含义（基本用法）不定式：表示目的和将来；动词的ing：表示主动和进行；过去分词：表示被动和完成。三、非谓语动词的时态和语态一般式完成式进行式不定式主动to doto have doneto be doing被动to be doneto have been doneing 形式主动doinghaving done被动being donehaving bee
2、n done过去分词被动done四、非谓语动词的否定形式在非谓语动词前加not, never. 即 not / never to do, not / never doing五、非谓语动词的复合结构不定式的复合结构：for / of sb. to do sth.授课：XXX动词 ing 形式的复合结构：宾格或所有格+doing (-ing 形式作主语时，用的所有格doing)六、非谓语动词的做题步骤1、判定是否用非谓语形式。方法：看看句子中是否已有了谓语动词了2、找非谓语动词的逻辑主语。方法：非谓语动词的逻辑主语一般是句子的主语。3、判断主被动关系。方法：非谓语动词与其逻辑主语的主动还是被动关系
3、。4、判断时间关系。方法：分析句子，看看非谓语动词所表示的动作发生在谓语动作之前、之后还是同时。之前常用 done; 之后常用to do; 同时常用doing.学习非谓语形式时，建议把三种形式一起来比较学习，会更加有效一些。七、非谓语动词作主语和表语的比较1、不定式和动名词作主语和表语a. 不定式表示一次性的、具体的动词。动词ing 常表示一般的、泛指的或习惯性的动作。如：_ is a good form of exercise for both young and old.A. The walk B. Walking C. To walk D. Walk(分析)a good form 暗示泛
4、指一般的行为，用动名词作主语，选Bb. 不定式作主语时，常用it 作形式主语，即用句型：It is + adj. / n. + (for / of sb. ) to do sth.Its important for us to learn English well.Its kind of you to help us.注意：下面几个句型是用动名词：Its no good / use doing sth.Its useless doing sth.授课：XXXThere is no need to do sth.2、不定式、动名词、分词作表语的比较1、不定式、动名词作表语，.表示主语的内容。如：
5、My job is teaching / to teach English. (teaching / to teach English 是my job的内容)Knowing who we are means knowing what we like to do.（主表语要用同一种形式）2、 分词作表语记住：一些表示情感、情绪的动词，常用分词形式作表语。现在分词表示主语的性质特征，用过去分词表示主语的状态。常用动词：surprise (使某人吃惊)， surprising (令人吃惊)， surprised (主语)感到吃惊）类似动词有：excite (激动)，astonish (惊奇)，sho
6、ck (震惊)，scare (惊恐)，disappoint (失望)，move（感动），如：The movie is exciting. We are excited at the news.3、 在seem / appear (似乎，好像)， prove/ turn out (被证明是)， remain (仍然是，尚待)等连系动词后，可用不定式作表语。如：He seemed (to be ) very happy. 非谓语动词十大解题原则非谓语动词主要包括to do, -ing和-ed三种形式，可是其用法非常广泛，它不仅是高考单项选择题测试的一个重点，而且也是完形填空、阅读理解、短文改错的重
7、要考查内容。为了能更好地掌握非谓语动词的用法，笔者在教学实践中总结出十条实用的解题原则，并且还用相关的题目来解释这些原则。根据这些原则，相信同学们可以轻松地应对非谓语动词。原则一、两个句子必须要用连词连接，如果没有连词连接，则需要用非谓语动词例1. _ many times, but he still couldnt understand it.A. Having been told B. Having told C. He had been told D. Though he had been told例2_ many times, he still couldnt understand i
8、t.授课：XXXA. Having been told B. Having told C. He had been told D. Though he had told解析：例1中有连词but连接，表明前后都是句子，所以答案为C。例2中后面是一个句子，而且没有连词，所以前面不是句子，应该用非谓语动词，根据句意此处为被动，所以答案为A。原则二、不及物动词无-ed形式非谓语动词，及物动词有宾语时用-ing形式，无宾语时用-ed形式例3. _ in the mountains for a week, the two students were finally saved by the local p
9、olice.A. Having lost B. Lost C. Being lost D. Losing解析：lose为及物动词，现在后面没有宾语，所以用-ed形式，答案为B。例4. _, I really believe that Id prefer not to make any change now.A. Considered all the possibilities B. Taking all the possibilities into considerationC. Taken all the possibilities into consideration D. Giving
10、all the possibilities解析：把。考虑进来结构为take sth into consideration，现在take后面有宾语all the possibilities，所以用-ing形式，答案为B。原则三、being done 表示“正在被”，一般不作状语，只作定语。非谓语动词的完成时形式to have done或having done强调该动作发生在句子谓语动词之前例5. _ to reach them on the phone, we sent an email instead.A. Fail B. Failed C. To fail D. Having failed解
11、析：根据句意“我们没有打通电话，就给他们发了个邮件”，没有打通电话应该发生在发邮件之前，所以用having done，答案为D。授课：XXX例6. Tim Bemers-Lee is generally considered _ the World Wide Web, on which all the information is shared by all.A. to have founded B. having founded C. founding D. to found解析：根据句意，Tim Bemers-Lee创立万维网应该是过去的事情，而且be considered后面应该用动词不
12、定式，所以应该用to have done，答案为A。原则四、非谓语动词作定语时，表示将来用-to do，表正在进行用-ing，表示已经完成用-ed例7. The play_ next month aims mainly to reflect the local cultureAproduced Bbeing producedCto be produced Dhaving been produced解析：根据本题中的时间状语next month，可知the play将要于下月被创作出来，表将来应该用to do，所以答案为C。例8.The trees _ in the storm have bee
13、n moved off the road.A. being blown down B. blown down C. blowing down D. to blow down解析：根据句意“被暴风雨刮倒的树已经从路上移走了”，树被刮倒是过去已经完成的动作，表已经完成用-ed形式，所以答案为B。原则五、介词后跟-ing形式，可以在-ing前加逻辑主语例9. The discovery of new evidence led to _.A. the thief having been caught B. the thief to be caughtC. catch the thief D. the
14、thief being caught解析：本题led to中的to是介词，后面应该用-ing形式，the thief作-ing的逻辑主语，所以答案为D。授课：XXX例10. At the beginning of class, the noise of desks _ could be heard outside the classroom.A. opened and closed B. to be opened and closedC. being opened and closed D. to open and close解析：本题the noise of中的of是介词，后面应该用-ing
15、形式，desks作-ing的逻辑主语，所以答案为C。原则六、-ing形式或to do可作主语或宾语，-ed形式则不可以例11. _ in a heavy traffic jam is quite an unpleasant experience.A. Caught B. Having caught C. Being caught D. To catch解析：本题中is为系动词，前面应该作主语，用-ing形式，所以答案为C。例12 _twice a year, whether it is a car or a bus or a truck, is the rule that every driver must obey in this city.A. E
