非谓语动词语法讲解学生版.doc

. 非谓语动词语法讲解一、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 been 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.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。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. Walkb. 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.There 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：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)，shock (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.
