实义动词的一般现在时

一、什么叫实义动词？ 实义动词是指表示某种动作行为 ,

有具体意思的动词 , 也叫行为动词。如 : like, eat, live, have, run 等等，它们的意思分别是：“喜欢”、“吃”、“居住”、“有”、“跑”等等，这些都是实义动词。实义动词占英语中动词的绝大多数。

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。

二、人称的划分

1. 第一人称 : I, we

第二人称 : you

第三人称 : he, she, it, they,

Millie…

2. 第三人称单数 : 第三人称中指一个人或事物的代词或名词 , 如 : he,

she, it, Millie, his friend, the dog 等。

你能再举出一些第三人称单数的例子吗？

三、 一般现在时实义动词作谓语时 的动词形式： 一般现在时实义动词作谓语时的动词形式有两种 : 动词原形或第三人称单数动词形式 ( 如 : enjoy 叫原形 , enjoys

叫第三人称单数形式 ) 。

四、实义动词第三人称单数的动词形 式变化规则 :

绝大多数动词 +s walk—walks

辅音字母 +y 结尾的动词

将 y改为i+es

fly—flies

以 s, x, ch, sh 结尾的动词 +es watch—watches

一些以 o 结尾的动词 +es

go—goesdo—does

1. 肯定句 :

(1) 第三人称单数主语 + 第三人称单数的谓语动词 +……

He enjoys playing football.

(2) 其他人称的主语 + 动词原形 +……

I like my school very much.
