一般现在时(二)
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。
例如: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动词可译为是,有时译为成为,有时则没有具体意思，如She is tall，这句话译为她很高。故be动词不属于实义动词。
2.一般现在时实义动词做谓语的时候有两种形式
- 动词原型，如:like
- 第三人称单数动词形式,如:likes
语法
主语 + 行为动词原形 | 行为动词的单数第三人称形式 （+宾语）
例句
We study English.
He studies Chinese
3.实义动词第三人称单数的动词形式变化规则
| 规则 | 示例 |
|---|---|
| 一般情况下直接加-s | walk-walks |
| 以s、x、sh、ch、o结尾的加-es | watch-watches go-goes |
| 辅音字母+y结尾的变y为i再加-es | fly-flies |
| 特殊情况 | have-has |
💡变化对象为实义动词，与名词单复数变化规则相似，切勿混淆
4.实义动词的一般现在时的基本句型
肯定句
主语(I/We/You/They[非三单]) + 实义动词原形 + 宾语

主语(He/She/It) + 实义动词三单形式 + 宾语
He likes music very much.
Lucy has a big house.
否定句
助动词:do除了三单以外 does三单
语法:主语 + do + not + 动词原形 + 宾语
