2017考研英语语法小讲:一般现在时
通常以动词原形表示。主语为第三人称单数时,用现单三形式。
动词be和have(表示“拥有”)各人称的单数形式为:
| 第一人称单数 | 第二人称单数 | 第三人称单数 |
Have | Have | Have | Has |
Be | Am | Are | is |
一般现在时的否定式、疑问式和简单回答形式如下:
动词be 与 have(表示“拥有”):否定式直接把not放在动词之后,疑问式直接把动词放在主语之前,见下表:
否定式 | 疑问式 | ||
Be | Have | Be | Have |
I am not (I’m not)… | I have not (haven’t)… | Am i…? | Have i…? |
You are not (aren’t)… | You have not (haven’t)… | Are you…? | Have you…? |
He is not (isn’t)… | He has not (hasn’t)… | Is he …? | Has he …? |
动词be 的否定疑问式和简单回答:
否定疑问式 | 肯定回答 | 否定回答 |
Am I not (aren’t i)…? | Yes, you are. | No, you aren’t |
Are you not (aren’t you)…? | Yes, I am. | No, I’m not. |
Is he not (isn’t he)…? | Yes, he is. | No, he isn’t |
动词be 与 have(表示“拥有”):否定式直接把not放在动词之后,疑问式直接把动词放在主语之前,见下表:
否定式 | 疑问式 | ||
Be | Have | Be | Have |
I am not (I’m not)… | I have not (haven’t)… | Am i…? | Have I …? |
You are not (aren’t)… | You have not (haven’t)… | Are you …? | Have you…? |
He is not (isn’t)… | He has not (hasn’t)… | Is he …? | Has he …? |
动词have(表示“拥有”) 的否定疑问式和简单回答:
否定疑问式 | 肯定回答 | 否定回答 |
Have I not (haven’t i)…? | Yes, you have. | No, you haven’t. |
Have you not (haven’t you)…? | Yes, I have. | No, I haven’t. |
Has he not (hasn’t he)…? | Yes, he has. | No, he hasn’t. |
注意:have 作为行为动词则只能按照行为动词的规则变化。
行为动词(以study为例)一般现在时的否定式、疑问式和简单回答(注意要加助动词do/does)
否定式 | 疑问式 |
I do not (don’t) study | Do I study |
You do not (don’t) study | Do you study |
He does not (doesn’t) study | Does he study |
