动名词、动词不定式、分词作定语区别.doc

动词的不定式,分词.动名词的区别及其用法、搭配。答：非谓语动词包括动词不定式。动名词和分词三种形式,分词又包括现在分词和过去分词。这三种形式都是由动词变来的,但在句子中都不能作谓语,故这三种形式被称为非谓语动词。下面就这三种形式在用法上的区别浅析如下: 一、动词不定式和动名词在句子中均可作主语和表语在表示一个具体的。个别的或将来的动作时,要用动词不定式。如: My job is to teach the first-year students grammar. To study English well is very important. 在表示比较抽象的一般的行为和动作时,二者可以互换。如: To climb mountains is a good form of exercise. Climbing mountains is a good form of exercise. 二、动名词、现在分词和动词不定式都可以作定语1.动名词作定语时,和它所修饰的名词之间没有逻辑上的主谓关系,只表示被修饰名词的一般用途,必须位于名词之前。如: There is a swimming pool in our school. 2.现在分词作定语时,和它所修饰的名词之间有逻辑上的主谓关系,表示所修饰名词的特征。如: Listen to the singing bird. Who is the boy running towards us。3.动词不定式作定语时,当所修饰的名词指人时,和它所修饰的名词之间有逻辑上的主谓关系。如: He is always the first to come to school. 当所修饰的名词指物时,和它所修饰的名词之间有逻辑上的动宾关系。如: I have a meeting to attend. 如果作定语的动词不定式中的动词是不及物动词,需加上相应的介词。如: I have no room to live in. There is nothing for me to worry about. 三、动词不定式和分词均可作宾语补足语动词不定式作宾语补足语时,表示动作已经发生,动作的全过程已经结束。如: I heard him knock at the door three times.(=I heard he knocked at the door three times (动作的全过程已经结束) 现在分词作宾语补足语时,表示动作正在进行。如: I heard him knocking at the door.(= I heard he was knocking at the door.(动作正在进行) 过去分词也可以作宾语补足语。如: I found the glass broken.(= I found the glass was broken.) 注意:动词不定式作宾语补足语时,在动词make,let,have,see,notice,hear,watch, observe,feel,listen to等后面要省略不定式符号to。如: I hear him play. The teacher made him do the exercises again. help后的动词不定式作宾语补足语时,不定式符号to可加可不加。如: He often helps me to study English in his spare time. 当这些动词变为被动语态时,原不定式必须加上to。如: He was seen to repair the machine. 四、动词不定式和动名词均可作宾语1.下列动词后只能跟不定式作宾语: hope, agree, decide, manage, wish, refuse, dare, promise等。如: He has promised to lend me the dictionary. 2.下列动词后只能跟动名词作宾语: enjoy, finish, avoid, practise, mind, escape, excuse, suggest, consider(考虑), give up, cant help等。如: He wants to give up smoking. They practise speaking English every day. 3.在动词remember,forget,regret,stop,try等后面跟动词不定式或动名词时,意义上有所差别。如: He forgot telling me the news.他忘了曾经告诉过我这个消息。He forgot to tell me the news.他忘了要把这个消息告诉我。五、动词不定式和分词均可作状语不定式作状语通常表示目的或程度;分词作状语通常表示伴随情况。时间或原因等。如: He went to the library to borrow a book (表目的) The boy sat at the desk reading a book.(表伴随情况) 六、动词不定式和动名词均有复合结构不定式的复合结构:for sb.(not) to do sth. 动名词的复合结构:名词所有格或形容词性物主代词+动名词。如: Its important for us to learn English well. He prided himself upon his dancing.
