小学英语动词to do、动词ing和动词原形的用法总结

运用技巧

动词to do（不定式）、动词ing（动名词）以及动词原形这三种动词形态是小学英语考试的一个重难点，也是困扰很多学生的一个难题，下面讲解下这三种基本动词形态的区别。

一、动词原形怎么用？

1、语法层面。一般现在时中，主语非第三人称单数，其后的动词用原形。如：

We all like learning English.（we不是第三人称单数，其后like用原形）

2、句式层面。祈使句（表达命令、要求、劝告、警告、禁止等的句子）开头的动词用原形。如下2例：

（1）Be quiet！all of you.（你们所有人都要保持安静！）

（2）Don't do your homework late at night! or you will be late for school tomorrow. （晚上不要做你的家庭作业太晚，否则你明天将会上学迟到）

3、用词搭配层面。分几种情况：

（1）情态动词。如can/could/should/must/will等后面动词用原形。例：

Daniel can play basketball well.（情态动词can紧随其后的动词用原形）

（2）固定搭配。

let sb do sth./make sb do sth./ help sb do sth.

例：Let's have some fun!（让我们玩的开心）

（3）助动词。如do/does/did以及它们的否定形式，后面跟动词原形。

例：Does she read newspapers?（does后紧随其后的动词用原形）

（4）why not do sth.为什么不做某事

例：Why not sing a song?（为什么不唱首歌呢？）

二、动词to do怎么用？

1、语法层面。动词to do 形式表目的，意为“为了……/去干……”，放在句首的时候表达“为了”，放在句中或句末时表达“去干”，下面举3个例子说明：

例1：To keep safe, you shouldn't run on the road.（为了保持安全，你不应该在路上跑）

例2：What should you do to cross the road safely?（你应该做什么去安全地穿过马路？）

例3：Beijing is a beautiful place to travel.（北京是一个去旅游的好地方）

2、句式层面。It' s time (for sb) to do sth./ It' s +形容词+(for sb)+ to do sth

例1：It' s time to have class.（该上课了）

例2：It' s easy for me to drive.（对我来说，开车很容易）

3、用词搭配层面。

（1）want to do / would like to do想要干某事

（2）ask sb to do / tell sb to do/invite sb to do叫/告诉/邀请某人做某事

（3）plan to do 计划做某事

（4）have to do不得不做某事

（5）use sth. to do 用……去干……

（6）be ready to do sth.准备好干某事

（7）can't wait to do sth.迫不及待去做某事

三、动词ing怎么用？

1、语法层面。表达正在进行时态，be动词+动词ing结构。

例：He is playing the piano now.（他现在正在弹钢琴）

2、句式层面。动词ing开头充当名词作句子的主语。看2个例子：

例1：Swimming is good for your health.（游泳对你的身体好）

例2：Smoking too much is bad for you.（吸烟太多对你不好）

3、用词搭配层面。

(1) 固定搭配。like/love +doing喜爱干某事；finish doing完成干某事；keep doing 继续干某事

(2) 表示课程。Swimming/Dancing/ lesson

例：I am going to have a Dancing lesson this weekend.

(3) 表示标志。No Parking/ No Smoking

(4) 用在介词后面。be good at/ what about/how about+doing

例：What about having a picnic?

（5）go+动词ing，表达“去干什么”go fishing/swimming/shopping...例：Let's go fishing.

（6）be busy doing sth.忙于做某事

例：She is busy with her homework.

（7）thank sb for doing sth.感谢某人做某事

例：Thank you for helping me.

动词ing形式的用法

动词ing形式的用法一)Ving形式作定语分词短语作定语时，放在被修饰的名词之后；单个分词作定语时，放在被修饰的名词之前。例如： The man standing by the window is our teacher. Many frightened people rushed out of the burning building. Ving作定语主要表示动作和用途。 1. 表示动作（主动的、进行的动作）。 a waiting car = the car that is waiting a sleeping child 熟睡的孩子 The girl standing there is my sister. 站在那儿的女孩是我的姐妹。 [注意]现在分词作定语时，它表示的动作是正在进行或与谓语动词所表示的动作几乎同时发生，如果两个动作有先有后，一般不能用现在分词作定语，而要用定语从句。例如： The teacher criticized the student who had broken the window. 老师批评了打破窗户的学生。 2. 表示用途： the waiting room = the room for waiting 候车室 a working method 工作方法 He has a reading room. 他有一个书房。【比较】过去分词作定语：及物动词的过去分词表示被动，不及物动词的过去分词表示动作完成。例如： That is the book written by Lu Xun. 那是鲁迅写的书。 He is a returned student. 他是一个归国的留学生。不定式作定语：用不定式作定语，其经常所修饰的名词、代词有：

小学英语助动词用法归纳

助动词（Auxiliary Verb）：协助主要动词构成谓语动词词组的词。自身没有词义，不可单独使用。主要动词（Main Verb）：是被协助的动词，构成时态和语态。 He doesn't like English. 他不喜欢英语。（doesn't是助动词，无词义；like是主要动词，有词义) 最常用的助动词有：be, have, do, shall, will, should, would 等。基本助动词只有三个：be, do, have 他们没有词汇意义，只有语法作用，如协助构成进行时，完成时，被动态，否定句，疑问句等。一、be 动词的用法既可作系动词，又可作助动词，做助动词有人称和数的变化，第一人称用am,第二人称及复数用are,第三人称及单数用is，am,is 过去式

为was, are的过去式为were,它与现在分词构成进行时态和过去分词一起构成被动语态。 a. 表示时态be+doing（现在分词）表示现在进行的动作 He is singing. 他正在唱歌。 b. 表示语态be+done(过去分词）表被动语态 He was sent to England. 他被派往英国。 c. be+to do（动词不定式）表示计划安排命令。 We are to plant trees next week. 下周我们将要去植树。 You are to explain this 。对此你要做出解释。二、do的用法 Do主要帮助实意动词构成否定和疑问句，后跟动词原形，有时放在实意动词前起强调作用，还可代替前文出现的动词，避免重复。Do 有人称和数的变化，第一、二人称及复数用do，第三人称及单数用does，过去式为did。 1）构成一般疑问句。DO +主语+动词原形+其他 I like singing 变为疑问句为Do you like singing ? 2）do + not 构成否定句。主语+do +not +动词原形。 I do not want to be criticized.我不想挨批评。 He doesn't like to study.他不想学习。 Many students didn’t know the importance of English before.过去好多学生不知道英语的重要性. 3)构成否定祈使句。
