初中英语非谓语动词详解 教案
展开非谓语动词
非谓语动词指的是在句中起名词，形容词或副词作用的动词形式，而不是作谓语的动词形式。 动词的非谓语形式分为动名词，分词，动词不定式。
Climbing mountain is a good exercise. (Climbing..., 动名词起名词作用）
Do you know the man wearing a white shirt. （wearing ..分词起形容词作用）
He gets up early to catch the first bus. (to catch ...不定式起副词作用)
谓语动词和非谓语动词的区别：
1) 谓语动词在句中可单独作谓语，而非谓语动词不能单独作谓语。
Miss Mary teaches us English. 玛丽教我们英语。（teaches 动词作谓语）
Mr. Li came to our classroom to have a talk with us last week.
（to have a talk.... 不定式作状语）
2) 谓语动词受主语的人称和数的限制，而非谓语动词形式没有这种限制。
Mike likes the pop music. （动词用单数第三人称形式）
Lucy has nothing to do today。（do 用原形）
非谓语动词的形式变化：
不定式 主 动 被 动
一 般 to write to be written
进 行 to be writing
完 成 to have written to have been written
完成进行 to have been writing
现 在 分 词 主 动 被 动

过去分词 主动 被 动
一般 written
动名词 主动 被 动
一般 writing being written
完成 having written having been written
●动 词 不 定 式：
动词不定式是由 to + 动词原形构成，在句中起名词，形容词和副词的作用，可以担任除谓语以外的其它任何成分。(主语,宾语，宾语补足语，表语，定语，状语)
1. 动词不定式作主语：
To master a language is not an easy thing.
To teach English is my favorite.
It's my pleasure to help you.
动词不定式作主语时可以放在后面，而用 it 作形式主语放在原主语的位置上。
It's very kind of you to have given us much help.
你给了我们那么多的帮助真是太好了。
It's necessary to find the witness. 有必要找到目击者。
2. 动词不定式作宾语：

3. 动词不定式作宾语补语 。

老师告诉我们不要在那条河里游泳。

带疑问词的不定式：
疑问词who, what,which,when, where, how, why 可以加在不定式的前面，构成不定式短语，使含义更加具体。

带逻辑主语的不定式：
动词不定式可以带有自己的逻辑主语，构成方法是： for + 逻辑主语 + 不定式。
注意：逻辑主语用宾格形式， for 本身无实际意义，它只表明后面的主语从逻辑上分析是不定式的主语。
It's necessary for us to help each other. 我们互相帮忙是必要的。
There are much work for me to finish, 有许多工作要我去完成。
动词不定式的被动形式： 表示不定式动词同所修饰的名词是被动关系 。

● 动 名 词
动名词是由动词原形 + ing 构成，同现在分词形式一样，在句中可作主语， 宾语，表语和定语。
1) 动名词作主语：

动名词的被动形式 ：

动名词的几种特殊情况：

4) 动名词和分词的区别：
动名词作定语时，动名词和它所修饰的词没有逻辑上的主谓关系，而分词作定语时， 分词和它所修饰的词有逻辑上的主谓关系。

● 分 词
分词是由动词 +ing 或 动词 + ed 构成，它在句中起形容词或副词的作用，可以作定语，表语，状语。 working worked washing washed
分词可分为现在分词和过去分词两种，现在分词的形式同动名词一样，在动词后面加 ing 。 而过去分词的形式则在动词后面加 ed. 分词在句中可作定语，状语或表语。
1.分词作定语

分词和动名词都可以作定语，判断是分词还是动名词，可以根据它们和被修饰词有无逻辑上的主谓关系来判断， 有主谓关系的是分词， 否则判断为动名词。
