什么是“一般现在时”？

一般现在时用来描述经常性、习惯性的动作或状态，以及客观事实、真理或普遍情况。

你可以把它想象成“新闻联播”的语气，陈述一个稳定、不变的事实或规律。

什么时候使用一般现在时？

记住以下这四大核心用法,你就能判断什么时候该用它了。

用法1：表示习惯性、经常性的动作

通常与表示频率的时间状语连用。

- always (总是)
- usually (
- often (经常)
- sometimes (有时)
- seldom / rarely (很少)
- hardly ever (几乎从不)
- never (从不)
- every day/week/month... (每天/每周/每月...)
- on weekdays (在工作日)
- once a week (每周一次)
例句：
- I get up at 6:30 every morning. (我每天早上6:30起床。)
- He usually plays basketball after school. (他通常放学后打篮球。)
- My mother cooks dinner for us every day. (我妈妈每天为我们做晚饭。)

用法3：表示现在所处的状态

指主语现在的状态,比如情感、感觉、拥有等。

be 动词, feel, like, love, hate, have (拥有), want, need 等。
例句：
- I am very happy today. (我今天很开心。)
- He looks tired. (他看起来很累。)
- We have a new English teacher. (我们有一位新英语老师。)

用法4：在时间状语从句和条件状语从句中

如果主句是一般将来时（will do），那么在 if, when, as soon as, before, after 等引导的从句中，要用一般现在时代替一般将来时。

if, when, as soon as, before, after
例句：
- I will call you as soon as I arrive in Beijing. (我一到北京就给你打电话。)
- If it doesn't rain tomorrow, we will go hiking. (如果明天不下雨，我们就去远足。)
- He will wait for you until you come back. (他会等你回来。)

一般现在时的构成

这是语法最关键的部分,也是最容易出错的地方，主要分为 be 动词、实义动词和情态动词三种情况。

be 动词 (am, is, are)

be 动词的用法相对简单，关键是根据主语选择正确的形式。

主语	be 动词形式
I	am
He / She / It (单数)	is
You / We / They (复数)	are

肯定句结构：主语 + be动词 + 其他.

I am a student.
He is from China.
They are playing football.

否定句结构：主语 + be动词 + not + 其他.

I am not a teacher.
She is not (isn't) at home.
We are not (aren't) busy.

一般疑问句结构：Be动词 + 主语 + 其他？

Are you a student? (是的, I am. / No, I am not.)
Is he your friend? (是的, he is. / No, he isn't.)
Are they from Japan? (是的, they are. / No, they aren't.)

实义动词 (do / does)

这是最核心、最复杂的部分，也是七年级的重点和难点。

A. 肯定句

主语是 I / You / We / They (复数) 时，动词用原形。
- I like English.
- They play games every day.
- We go to school on foot.
主语是 He / She / It (单数) 时，动词要加 -s 或 -es。
- He likes English. (like -> likes)
- She watches TV in the evening. (watch -> watches)
- It runs fast. (run -> runs)

B. 否定句

结构：主语 + don't/doesn't + 动词原形 + 其他.
- 注意：无论主语是单数还是复数，否定句和疑问句中永远用动词原形！
主语是 I / You / We / They (复数) 时，用 don't。
- I don't like English.
- They don't play games every day.
主语是 He / She / It (单数) 时，用 doesn't。
- He doesn't like English.
- She doesn't watch TV in the evening.

C. 一般疑问句

结构：Do/Does + 主语 + 动词原形 + 其他？
- 注意：同样，动词必须用原形！
主语是 I / You / We / They (复数) 时，用 Do。
- Do you like English? (是的, I do. / No, I don't.)
- Do they play games every day? (是的, they do. / No, they don't.)
主语是 He / She / It (单数) 时，用 Does。
- Does he like English? (是的, he does. / No, he doesn't.)
- Does she watch TV in the evening? (是的, she does. / No, she doesn't.)

动词第三人称单数变化规则

当主语是第三人称单数时,动词需要变形，记住下面这个口诀：

直接加 -s

play -> plays
work -> works
get -> gets

以 s, x, ch, sh, o 加 -es

watch -> watches
teach -> teaches
go -> goes
fix -> fixes

辅音字母 + y 变 y 为 i 再加 -es

study -> studies
fly -> flies
try -> tries

特殊变化

have -> has
be -> is
do -> does

情态动词 (can, must, should...)

情态动词后面永远跟动词原形，它们不受主语人称和数的影响。

肯定句：主语 + 情态动词 + 动词原形 + ...
- I can swim.
- You must finish your homework.
- He should go to bed early.
否定句：主语 + 情态动词 + not + 动词原形 + ...
- I can't (cannot) swim.
- You mustn't (must not) be late.
- He shouldn't (should not) play games too much.
疑问句：情态动词 + 主语 + 动词原形 + ...?
- Can you swim? (Yes, I can. / No, I can't.)
- Must I finish it now? (Yes, you must. / No, you needn't.)
