快速学会非谓语动词的方法.ppt

* * 非谓语动词，意思就是不能在句中充当谓语。但是，作为一个动词，它还是有个动作的执行者（主动关系）或承受者（被动关系），我们将之称为其“逻辑主语”。 下面的练习要求是 ： A： 找出该非谓语的逻辑主语，并指出与该动词是主动关系还是被动关系； B: 指出非谓语的动作是发生在主句动作之前还是之后； C: 或指出其在句中所作的成分； 1.????? Having realized that I could use kite to attract the lightning, I decided to do the experiment. 2.????? The bell rang, all the boys and girls went out of their classroom, singing and jumping. 3.????? The boys swimming in the sea were in danger. 4.????? They hearing the news, their tears came down their cheek. 5.????? When taken following its directions, the drug has no neglect effect — 主动 ———————— 主动 ——— 主动 ——— 主动 ——— 被动 二.感受从一般句子转换为含非谓语部分（分词）的句子 方法（一）：由定语从句改为分词短语的方法： 1.若关系词之后有?be 动词(限be 在结构be+V-ing或be+V-ed中时)—则删去关系代词和be，其它成分不变。 Eg. A). Watch the men who are coming this way. Watch the man coming this way. B). Lessons which are learned easily are soon forgotten. C). The dog was beaten yesterday is dead. Lessons learned easily are soon forgotten. The dog beaten yesterday is dead. 2．若关系词之后没有?be 动词(限be 在结构be+V-ing或be+V-ed中时)而是一般的动词———则删去关系词，再将动词改为-ing形式,其它不变。 A). Anyone who wishes to leave early may do so . Anyone wishing to leave early may do so . The boy sitting near the window was good at playing football. We see the stream rising from the hole. B).The boy who sat near the window was good at playing football. C) We see the stream which rises from the hole. 方法（二）：由状语从句改为分词短语的方法。 A）. 先将引导状语从句的连接词去掉。 B）.如果状语从句的主语与主句主语相同， 则去掉从句主语； 不相同， 则保留从句主语（亦称独立主格结构） C）. 再将原状语从句的谓语动词变成—ing 形式， 补充：当状语从句的谓语含有be+V-ing（进行时结构）或be+V-ed（被动式）时，也可能将be 去掉,其它部分不变。 注意：若主句动词为现在时，而状语从句的动词为过去时，那么为了表示状语从句的动作时间早于主句的动词，则变分词短语是应改为完成式。 转换练习： 1.状语从句主语与主句主语相同。（逆向法：即分词的逻辑主语就是主句的主语） 1).
