1、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：todo2、动词的ing:doing3、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不定式主动一般式todo完成式进行式tohavedonetobedoinging形式被动主动被动tobedonetohavebeendonedoinghavingdonebeingdonehavingbeendone过去分被动done词四、
2、非谓语动词的否定形式在非谓语动词前加not,never.即not/nevertodo,not/neverdoing五、非谓语动词的复合结构不定式的复合结构：for/ofsb.todosth.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
3、同时。之前常用done;之后常用todo;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：_isagoodformofexerciseforbothyoungandold.A.ThewalkB.WalkingC.TowalkD.Walkb.不定式作主语时，常用it作形式主语，即用句型：Itis+adj./n.+(for/ofsb.)todosth.ItsimportantforustolearnEnglishwe
4、ll.Itskindofyoutohelpus.注意：下面几个句型是用动名词：Itsnogood/usedoingsth.Itsuselessdoingsth.Thereisnoneedtodosth.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：Myjobisteaching/toteachEnglish.(teaching/toteachEnglish是myjob的内容)Knowingwhowearemeansknowingwhatweliketodo.（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
5、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：Themovieisexciting.Weareexcitedatthenews.3、在seem/appear(似乎，好像)，prove/turnout(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：Heseemed(tobe)veryhappy.非谓语动词十大
6、解题原则非谓语动词主要包括todo,-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._manytimes,buthestillcouldntunderstandit.A.HavingbeentoldB.HavingtoldC.HehadbeentoldD.Thoughheha
