名词所有格：表示名词的所属关系。译为”.......的“。
何谓“所属关系”？
Possessive case of nouns 名词所有格
是指一个事物属于另一个事物的关系。

Teng Fei’s grandfather loves sport.
They have some nice ping-pong bats.
Teng Fei’s father has a fishing rod.
名词所有格
2. 复数名词后，因名词本身以s结尾，因此直接+’(’s所有格)
e.g. 祖父母的房子
grandparents’ house
e.g. 学生们的姓名
students’ names
名词所有格修饰的名词如果是单个对象则用单数，多个对象用复数形式。

名词所有格与物主代词之间有联系吗？
它们可以互换使用吗？
名词所有格和物主代词都是用来表示所属关系的语法结构，
但在使用上存在一些区别。
结构 名词所有格 物主代词
用法 通常用于表示直接拥有，即某样东西直接属于某个人或物。 它可以通过在名词词尾加“'s”来构成。 包括形容词性物主代词和名词性物主代词，用于表示所属关系，但它们的使用更加灵活。
形容词性物主代词（如my, your, his,）置于名词前，起修饰作用，表示某人的。
名词性物主代词（如mine, yours, his,）则用来直接作为句子的主语或宾语，表示某物属于某人。
例句 John's car（约翰的车） the dog's tail（狗的尾巴） This is my book.（这是我的书。）
That car is hers.（那辆车是她的。）
注：两者在不影响表达的情况下可以互换使用，物主代词有简化语言的作用。 1. Teng Fei’s grandfather loves sport. (his)
腾飞的爷爷喜欢运动。
2. This is Peter and Emma’s classroom. (their)
这是彼得和埃玛的教室。
3. This is Kate’s cat. (her)
这是凯特的猫。
Let’s watch a video and find the rules.

总结规律：
当主语是第三人称单数时，实义动词使用其第三人称单数形式（简称三单形式）。其余情况均用动词原形。
一般现在时
主系表
（be动词的一般现在时）
句子结构 主语 + 系动词 + 表语
·主语 ：句子中的主要行动者或描述对象，如I, he, the book等。
·系动词 ：连接主语和表语的动词，
表示主语的状态或特征，如am, is, are, look, seem等。
·表语 ：描述主语状态、身份或特征的成分，可以是名词、形容词、副词、介词短语等，如happy, a teacher, here等。
例句 My name is Amy.
He is ten years old.
一般现在时：1.表示现在的状态：
e.g. My name is Jack. I am twelve.
我叫杰克。我12岁了。
在Unit 1的语法课中，我们学习了含be动词的一般现在时，即：主系表结构。
一般现在时的构成1：
今天我们将学习：
实义动词的一般现在时！！！
The simple present tense (do)
一般现在时：
2.表示经常的或习惯性的动作：
e.g. He gets up at six.他六点钟起床。
3.表示主语具备的特征或能力等：
e.g. She likes English a lot.她很喜欢英语。
4.表示客观存在或普遍真理等：
e.g. Cats eat fish. 猫吃鱼。
The earth goes around the sun. 地球围绕太阳转。
一般现在时的构成2：
主谓宾
（实义/行为动词的一般现在时）
句子结构 主语 + 谓语（实义动词）+ 宾语
·主语 ：句子中的主要行动者或描述对象。
·谓语（实义动词） ：表示主语的动作或状态的动词，如eat, write, love等。
·宾语 ：动作的对象或承受者，回答“谁”或“什么”的问题，
如 apples, him, the book等。
例句 I often play football after school.

1. I _______ (go) swimming on Sundays.
2. My cousin _________ (enjoy) computer games.
3. My parents __________ (watch) TV in the evening.

动词基本形式及变形

含实义动词的一般现在时的用法
实义动词作谓语，位置就在主语后；
主语三单要注意，动词变化别忘记；
一般疑问很好变，句首莫忘把do/does添；
否定句子也不难,don't/ doesn't加在实义动词前;
凡是 does (doesn't)句中现,实义动词要还原。
变一般疑问句时，需要变化的词如下： 人称代词/物主代词 I/me/we/you→you; my/our→your; mine→yours
其他词类 some→any; and→or; too→either
