Unit1 This is me
⭐Reading知识点清单
一、核心基础概念
1. 语法名称
Simple present tense (I) 一般现在时(第一讲:be 动词)
2. 使用场景(课本原文核心规则)
一般现在时中 be 动词用来描述客观事实、长久状态:
- 介绍人物身份、年龄、班级:I am Millie. I’m 12 years old.
- 描述人 / 事物特征、性格:They are friendly. She is tall.
- 表达喜好、兴趣、能力状态:He is good at sport. I am interested in music.
- 介绍客观存在的事物:It is a nice school. This is our classroom.
3. be 动词三兄弟:am /is/are 人称匹配规则(必考核心)
主语 | 搭配 be 动词 | 简写形式 |
第一人称单数 I(我) | am | I am = I’m |
第二人称单复数 you(你 / 你们)、复数主语 we(我们)、they(他们 / 她们 / 它们) | are | you are = you’re;we are = we’re;they are = they’re |
第三人称单数 he(他)、she(她)、it(它)、单个的人 / 事物 | is | he is = he’s;she is = she’s;it is = it’s |
记忆口诀:I 用 am,you 用 are,is 连着他她它;单数 is,复数 are
二、be 动词三大句式结构(肯定句、否定句、一般疑问句)
(一)肯定句
句型结构:主语 + am/is/are + 表语(名词 / 形容词 / 介词短语)
- I am at Sunshine Middle School.(介词短语作表语)
- She is interested in music.(形容词短语作表语)
- They are my new classmates.(名词作表语)
- We are friends.
(二)否定句(be 动词后直接加 not)
- 完整形式
I am not;you/we/they are not;he/she/it is not

- 缩写形式(考试高频考点)
are not = aren’t;is not = isn’t
✨ 重点:am not 无缩写,不能写成 amn’t
例句:
I am not twelve.
They aren’t friendly.
It isn’t easy.
(三)一般疑问句(be 动词提前放句首,句末改问号)
- 句型结构:Am/Is/Are + 主语 + 表语?
- Am I happy?
- Are you good at football?
- Is he our English teacher?
- 问答配对(回答必须对应问句的 be 动词,不能混用)
- Am I…? — Yes, you are. / No, you aren’t.
- Are you/we/they…? — Yes, I/we/they are. / No, I/we/they aren’t.
- Is he/she/it…? — Yes, he/she/it is. / No, he/she/it isn’t.
⚠️ 易错点:简答末尾只用 be 动词,不能带形容词 / 名词,如不能回答 Yes, I am happy.
三、高频固定搭配(be + 形容词短语,本单元必考)
- be at + 地点 在某地
I am at school. 我在学校。
- be friendly 友好的
They are all very friendly.
- be interested in sth. 对…… 感兴趣
She is interested in music.
- be good at sth./doing sth. 擅长……
He is good at sport.
- be happy 开心的
Are you happy at your new school?
- be new and clean 崭新干净
The school is new and clean.
- be hard for sb. 对某人来说很难
English is hard for me.
