一文讲清单复数、人称、特殊结构的动词一致规则
一、什么是“主谓一致”？
简单说：主语是谁，动词就要跟着“变脸”。
这在英语里不是选项，而是“硬性规定”。
二、主谓一致的6大核心规则
1⃣ 主语为第三人称单数，动词加 -s
She likes pizza.
Tom goes to school.
2⃣ 主语为复数，动词用原形
They play football.
My parents work hard.
3⃣ 并列主语当复数看
Tom and Jerry are famous.
My brother and I have lunch.
4⃣ 单数不可数名词后，动词单数
Water is important.
Money makes people nervous.
5⃣ 不定代词（everyone, somebody, etc.）= 单数
Everyone is here.
Somebody wants to speak.
6⃣ there be 结构：动词和“第一个主语”一致
There is a cat and two dogs.
There are many students in the hall.
三、易错点对比分析
| 错误句 | 正确句 | 错因 |
|---|---|---|
| She like coffee. | She likes coffee. | 忘记三单+s |
| The team are winning. | The team is winning. | 集体名词看整体作单数 |
| There is two boys. | There are two boys. | 第一个主语是复数 |
四、口诀记忆：
单主单谓要牢记，复主动词用原形；
三单记得加 -s，特殊代词别大意；
并列主语作复数，there be 要看谁先起！
五、实战建议（干货）
- 每写一句话，检查主语数（单/复）+ 动词是否配对
- 用【三单检测法】：主语是 he/she/it？动词就得+s
- 练习习惯：用一句话说两遍，改主语，看动词怎么跟变！
六、动手练（句子纠错）
改正以下句子中的主谓一致错误：
- He go to school every day.
- There is many people in the park.
- My mom and dad works hard.
- Each student have a book.
- The data shows interesting results.（此句对或错？为何？）
