一、含义

1. 经常性、习惯性动作

2. 客观真理、事实、常态

• I get up at 7 every day. 我每天7点起床。

• The earth goes around the sun. 地球绕着太阳转。

二、标志词（看到优先判断一般现在时）

• always, usually, often, sometimes, seldom, never，every day/week/month, on weekends

三、两大句型体系（重点区分：be动词 / 实义动词）

① be动词（am / is / are）

• 肯定：主语 + am/is/are + …

• He is a student.

• 否定：主语 + am/is/are + not + …

• He is not (isn’t) a student.

• 疑问：Am/Is/Are + 主语 + …？

• Is he a student?

• 回答：Yes, he is. / No, he isn’t.

② 实义动词（行为动词）

• 肯定：主语 + 动词(三单/原形)

• She likes English.

• They like English.

• 否定：主语 + don’t / doesn’t + 动词原形

• She doesn’t like English.（doesn’t后动词还原！高频坑）

• They don’t like English.

• 疑问：Do / Does + 主语 + 动词原形？

• Does she like English?

• Do they like English?

• 答：Yes, she does. / No, she doesn’t.

🎯三单变化规则回顾

1. 直接+s：play→plays
2. s/x/ch/sh/o结尾+es：watch→watches, go→goes
3. 辅音+y：变y为i+es：study→studies
4. 特殊：have→has
