二. 实义动词的一般现在时
1、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。
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。
2、一般现在时实义动词作谓语的时侯有两种形式:
动词原形;如: like
第三人称单数动词形式;如: likes
主语+ (+其它)。
{
实义动词原形
实义动词的单数第三人称形式
如:We like .
He likes French.
3、实义动词第三人称单数的变化规则
一般情况下直接加-s
walk—walks
以s. x. sh. ch. o
结尾加-es
watch—watches
go—goes
“辅音字母+y”结尾
变y为i, 再加-es,
fly—flies
study-studies
特殊情况
have→has do→does
1) 肯定句:
主语(I/We/You/They)+实义动词原形+其他
如:I stay at home on Saturdays.
