1、非谓语动词之分词 分词分词分词包括两种: 现在分词和过去分词。现在分词表示主动,进行的含义; 过去分词表示被动,完成的含义。 分词的句法功能分词的句法功能做定语做定语 单个分词一般放在被修饰的名词前。分词短语一般放在被修饰词之后, 相当于一个从句。 The young man sitting between John and Mary is the monitor of our class. (the young man who is sitting between John and Mary) 坐在约翰和 玛丽之间的年轻人是我们的班长。 He ate up the cake made by

2、his mother. (the cake which had been made by his mother)他吃光了他妈妈做得蛋糕。 注意: 如果定语从句和主句时态不一致, 不可以用分词代替从句 The young man who sat between John and Mary yesterday is our monitor.不可以变成 The young man sitting between John and Mary yesterday is our monitor. 谓语动词是be 或含有情态动词的定语从句也不能用分词代替 Those who are late are not

3、 allowed to come into the classroom.不可以变成Those being late are not allowed to come into the classroom. Will you find a workman who can repair the TV? 不可以变成Will you find a workman repairing the TV?做宾语补语做宾语补语 Catch, discover, feel, fin, get, have, hear , keep, leave, make, notice, see, watch 等动词后面常用分词作

5、earth is a blue planet. (=When it is seen from the space, the earth is a blue planet.)时间Being ill, he couldnt go to class.

6、) 原因He sat in an armchair, watching TV.(=He sat in an armchair and watched TV)伴随 注意: 用作状语的分词短语的逻辑主语必须和句子的主语一致。 Waiting for a bus, a stone hit me. (主句主语stone并不是分词waiting的发出者,可改为定语从句, 写出waiting 的主语: While I was waiting for the bus, a stone hit me.) Made of plastic, I didnt expect the chairs could be t

7、hat strong. (主句主语I不是分词made的发出者,可改为定语从句, 写出made 的主语: As the chairs were made of plastic, I didnt expect they would be that strong.).分词的不同形式分词的不同形式现在分词主动被动一般式doingBeing done完成式Having doneHaving been done否定NotHaving doneNot having been done完成式的用法完成式表示的动作发生在谓语动作之前,主要用做状语。Having finished shopping, she we

8、nt home.Not having heard from his parents for a long time, he was worried about them.被动形式的用法He is excited to hear his song being broadcast again and again on the radio.I noticed several flyovers being built in the city.The museum being built will receive visitors next year.He said he knew the girl b

11、;不定式作表语一般表示具体动作,特别是表示将来的动作;动名词作表语:动名词作表语,表示抽象的一般性的行为动名词作表语:动名词作表语,表示抽象的一般性的行为不定式作表语一般表示具体动作,特别是表示将来的动作。 To do two things at a time is to do neither一次做两件事等于未做。What I would suggest is to start work at once.我的建议是立刻开始干。如果主语是不定式(表示条件),表语也是不定式(表示结果)。 To see is to believe.To work means to earn a living工作就是

12、为了生活。如果主语是以aim,duty,hope,idea,happiness,job,plan,problem,purpose,thing,wish等为中心的名词,或以what引导的名词性从句,不定式作表语是对主语起补充说明作用。 His wish is to buy a luxurious car in the near future他的希望是在不远的将来买一辆豪华轿车。 动名词作表语:动名词作表语,表示抽象的一般性的行为。 Our work is serving the people 我们的工作是为人民服务。 His hobby is collecting stamps 他的爱好是集邮。

13、分词作表语 分词做表语有两种情况,一种是现在分词做表语, 一种是过去分词做表语,这两者区别是考试中经常考到的地方。现在分词修饰物表示 “令人的”;过去分词修饰人表示 “感到”。换句话说,若人对感兴趣,就是somebody is interested in.,若人/物本身有兴趣时,就是说sb./sth. is interesting.这类词常见的有: interesting使人感到高兴 -interested感到高兴的exciting令人激动的 - -excited感到激动的 delighting令人高兴的 -delighted感到高兴的 disappointing令人失望的 -disappoi

18、ave you got your watch repaired? 你拿到那个修好的表了吗?

19、doctor working on the case report in the office? 你要见那位正在办公室里写病历的医生吗?(正在写病历) Do you want to see the doctor sent for from Beijing? 你要见那位从北京请来的医生吗?(人已经请过来了)5 5不定式和分词作状语的区别不定式和分词作状语的区别 现在分词与过去分词作状语的区别。 现在分词做状语与过去分词做状语的最主要区别在于两者与所修饰的主语的主动与被动关系的区别。 现在分词作状语时,现在分词的动作就是句子主语的动作,它们之间的关系是主动关系。 He went out shutt

20、ing the door behind him. 他出去后将门随手关上。Not knowing what to do, he went to his parents for help. 由于不知如何办是好,他去找父母帮忙。 过去分词作状语时,过去分词表示的动作是句子主语承受的动作,它们之间的关系是被动关系 Given more attention, the trees could have grown better. 如果对这些树多关心一些,它们本来会长得更好。 Faced with difficulties, we must try to overcome them. 在遇到困难的时候,我们

23、对比时间:对照谓语动词的时间,确定非谓语动词的时态形式的时态形式 非谓语动词的各种时态形式都是依据句子的谓语动词的时态形式而变化的。一般情况下,如果非谓语动词所表示的动作在谓语动词所表示的动作之后发生,就用不定式的一般式;如果表示动作与谓语动词所表示的动作同时进行,就用现在分词的一般式或不定式的进行式;如果表示动作在谓语动词所表示的动作之前发生,就用现在分词、不定式或动名词的完成式(特殊情况下,也可用动名词的一般式)。 2辨明逻辑:从非谓语动词与其逻辑主语的关辨明逻辑:从非谓语动词与其逻辑主语的关系判断非谓语动词的语态系判断非谓语动词的语态如果非谓语动词的逻辑主语是非谓语动词动作的发出者,即两

24、者之间存在主谓关系,就用非谓语动词的主动式;如果逻辑主语是非谓语动词动作的承受者,即两者之间存在动宾关系,就用非谓语动词的被动式。 3. 两方面结合,判断时态、语态混合形式两方面结合,判断时态、语态混合形式 有些非谓语动词的形式把时态和语态的变化融合在一起,这时,我们可以把上述两方面结合起来判断。在非谓语动词的逻辑主语是非谓语动词动作的承受者的情况下, a)如果非谓语动词所表示的动作与谓语动词所表示的动作同时发生,就用现在分词的被动式; b)如果动作在谓语动词所表示的动作之后发生,就用不定式的被动式; c)如果动作发生在谓语动词所表示的动作之前,就用现在分词、动名词或不定式的完成被动式。强化闯
