一般现在时专项训练
(一) 动词第三人称单数形式变化规则
一、第三人称单数概念
在英语中, 句子主语可以分为第一人称、第二人称和第三人称。
第三人称又分为第三人称复数 (they, the students, my parents 等) 和第三人称单数。
除了I, we, you以及第三人称复数之外, 其余的名词或代词都属于第三人称单数。具体包括:
1. 人称代词 (he, she, it)
2. 单个人名、地名或称呼
3. 单数可数名词或this/that/the+单数可数名词
4. 不定代词 (someone, somebody, nobody, everything, something等)
5. 指示代词 (this, that)
6. 不可数名词
7. 数字或字母
二、一般现在时中, 动词随主语的变化而变化
在一般现在时的肯定句中, 动词的形式取决于主语。
1. 主语为第一人称 (I, we) 、第二人称 (you) 或第三人称复数 (they, my parents, the students等) 时, 动词用原形。如:
I get up at 6:30 every day. 我每天六点半起床。
2. 主语为第三人称单数时, 动词必须变成第三人称单数形式。如:
She gets up at 6:30 every day. 她每天六点半起床。
三、一般现在时中, 动词第三人称单数形式变化规则

一般情况下,直接在动词的词尾加- s
write→writes help→helps give→gives

以辅音字母加y结尾的动词,先变y为i,再加- es

(三) 含实义动词的一般现在时的否定句结构
一、概念
当我们想说某人不做某事或者不经常做某事时,就要用到一般现在时的否定句。在含实义动词的否定句中,不能直接在动词后面加not,而需要借助助动词do或does来帮助构成否定形式。
二、结构
主语+don't/doesn't+动词原形 (+其他)
1. 用don't的情况
主语是I/you/we/they或任何复数名词 (如my friends,the children,Tom and Jerry) 时。如:
I don't feel good. 我感觉不好。
You don't give up. 你别放弃。
We don't understand. 我们不理解。
2. 用doesn't的情况
主语是he/she/it或任何单数人名、单数事物 (如Tom,my sister,the dog) 时。如:
He doesn't feel happy. 他感觉不开心。
She doesn't study hard. 她学习不努力。
My brother doesn't like vegetables. 我的弟弟不喜欢蔬菜。
注意 doesn't是does not的缩略形式,don't是do not的缩略形式。
三、肯定句变成否定句的步骤
1. 找出原句中的主语。
2. 判断主语是不是第三人称单数 (he/she/it/单数人名/单数事物) 。
3. 如果是,在主语后加doesn't。
4. 如果不是,在主语后加don't。
5. 将原句中的动词改为原形。
6. 其余部分 (宾语、状语等) 保持不变。

一、一般疑问句
1. 结构:
Do/Does+主语+动词原形+其他?
主语
助动词
动词形式

he/she/it/单数名词/不可数名词

3. 例句:

Does your brother play football? →Yes, he does. /No, he doesn't.
注意 回答中的主语必须用人称代词主格 (如you→I, Tom→he, Mary and Lucy→they)。
二、特殊疑问句
1. 结构:特殊疑问词+do/does+主语+动词原形+其他?
2. 回答:主语+动词原形/动词第三人称单数形式+其他.
