分词
- 现在分词和过去分词的构成
现在分词由v.+ing - 过去分词v.+ed(规则动词)
现在分词和过去分词的区别:
1. 语态上:现在分词表主动,过去分词表被动
- Do you know the woman talking to Tom?
- The soldier wounded in the war has become a doctor.
2. 时态上:现在分词表进行,过去分词表完成
boiling water 正在沸腾的水(表正在进行)
boiled water 开水(表完成)
developing countries 发展中国家
developed countries 发达国家
a disappointing look 一个令人失望的表情
a disappointed look 一个失望的表情
⚠️注意: 修饰人的表情、脸色、情感等要用v-ed.
- With a disappointed look on his face, he looked very sad.
作定语
现在分词作定语表示 动作。如果是单词,放在被修饰的名词前:如果是短语,就放在被修饰的名调之后。
1. 现在分词表示正在进行,有主动的含义。
- 前置定语
- He is a promising young man.
- Make less noise. There’s a sleeping child.
2. 过去分词表示已经完成,有被动的含义。
- 后置定语
- The young man sitting between John and Mary is the editor of the campus newspaper.
3. 分词短语作定语必须置于被修饰词之后,相当于一个定语从句。
- Those (
whowish to join the club) should sign here. - Those (wishing to join this club) should sign here.
4. 当过去分词是单词时,一般用于名词前:如果是 过去分词 短语,则放在名词的后面。过去分词短语作定语相当于一个被动语态的定语从句。
- Our class went on an organized trip last Monday.
5. 过去分词作定语在意义上有两种可能:表示被动&完成,或只表完成。
- the question (discussed yesterday)done
- 昨天讨论的问题(即表示被动也表示完成)
作表语
1. 放在系动词后作表语(形容词)
- They were frighted at the sad sight.
- The present situation is inspiring.
-
⚠️注意: be+doing既可能表示现在进行时,也可能是现在分词作表语,它们的区别在于be+doing表示 进行的动作 是进行时,而表示 特征 时是系动词be与现在分词构成系表结构。
2. be+过去分词,如果表示 状态 是 系表结构,如果表示 被动 的动作是被动语态。
- The window is broken. 窗户破了。(系表结构)
- The window was broken by the boy. (被动语态)
作宾补
1. 现在分词 作宾语补足语 强调动作正在进行,常见动词:see,watch,hear,feel,find,notice,observe,listen to,look at,catch,leave,get,have,keep…
- Can you hear her singing the song in the next room?
- He kept the car waiting at the gate.
2. 过去分词 作宾语补足语表示 被动和完成,或无时间性:感官动词see,watch,hear,feel,find,notice,observe,listen to,look at和使役动词have,make,get等。
- I hear the song sung several times last wekk.
- He had his luggage checked an hour before his plane left.

非谓语动词解题七大原则
- 原则一:用作目的状语,原则上要用不定式。
- 原则二:用作伴随状语,原则上要用-ing。
- 原则三:用作结果状语时,可用-ing或不定式,其区别是,一般用-ing,表示一定逻辑的结果,即结果在意料之中。不定式作结果状语表示非逻辑的结果,即结果在意料之外。
- 原则四:凡是含有被动意义时,原则上要用过去分词。但是,如果所涉及的动作尚未发生,则用不定式的被动式;如果所涉及的动作正在进行,则用-ing的被动式。
- 原则五:非谓语动词作状语时,其逻辑主语原则上应与主句主语保持一致。
- 原则六:强调动作发生在主句谓语动作之前时,原则上要用完成式(根据情况可用不定式的完成式或-ing的完成式)。
- 原则七:用于名词后作定语时:用不定式,表示动作尚未发生;用-ing,表示动作正在进行;用过去分词,表示动作被动、完成。
