实义动词
什么叫实义动词?
实义动词是指表示有具体意思的动词,也叫行为动词。
如: like(喜欢), eat(吃), live(居住), have(有), run(跑) 等等。
实义动词占英语中动词的绝大多数。
注意:我们已学过的be 动词可译成“是”, 有时译成“成为”,有时则没有具体意思如: “She is tall.”这句译成: “她很高”。故be 动词不属于实义动词。
什么是第三人称单数???
一、人称代词he, she, it是第三人称单数。
如:He likes watching TV. 他喜欢看电视。
She has lunch at twelve. 她十二点吃午餐。
It looks like a cat. 它看起来像只猫。
二、单个人名、地名或称呼作主语;是第三人称单数。
如:Han Mei looks like her mother.

Uncle Wang often makes cakes. 王叔叔经常做蛋糕。
三、不定代词someone, somebody, nobody, everything, something等及指示代词this, that作主语时,是第三人称单数。
如: Everyone is here. 每个人都在这。
This is a pen. 这是一支钢笔。
That is an eraser. 那是一个橡皮。
四、不可数名词作主语时为第三人称单数。
如: The milk is in the glass. 牛奶在杯子里。
The bread is very small. 面包非常小。
五、当数字或字母作主语时,看作第三人称单数。
如: "6" is a lucky number.6是一个幸运数字。
"I" is a letter. I是一个字母。

实义动词的一般现在时用法小结
谓语动词是实义动词时, 其一般现在时的谓语动词形式有两种——第三人称单数或原形。其否定句和疑问句要借助于does或do来帮助构成。
助动词的用法小结
一、什么是助动词?
在英语中,助动词本身没有意义,只是帮助实义动词完成某些语法功能,如构成否定句、疑问句、简略答语等。
助动词主要有be,do,have等。
本节课我们主要探究do的基本用法。
二. 助动词do的基本用法
do有三种形式:
原形
现在式第三人称单数
过去式(这里只需对此有基本了解即可)
do的基本用法:
构成否定句
构成一般疑问句及回答
构成特殊疑问句
原形
肯定式: do
否定式: do not
缩略否定式: don’t
用法:do用在第一人称单复数、第二人称单复数和第三人
称复数做主语,且时态为一般现在时的句子中。
现在式第三人称单数
肯定式: does
否定式: does not
缩略否定式: doesn’t
用法:does用在第三人称单数做主语,且时态为一
般现在时的句子中。
注意:当does出现时,句子中用动词原形。
