➊ be动词am, is, are的用法 ➋人称代词与物主代词
➌ 特殊疑问句(询问姓名、来自哪里、身份)
考点一:be动词am, is, are的用法
I'm from the UK.
She's from Shandong, China.
解析:be动词的一般现在时有三种形式:am is are,含义“是”,需要根据主语的人称和单复数来选择搭配。
一、 be 动词与人称代词的用法
人称代词分为第一人称、第二人称、第三人称,单复数不同,搭配的be动词也不同:
1. 口诀:我 (I) 用 am,你 (you) 用 are,is 连着他 (he) 她 (she) 它 (it);单数名词用 is,复数名词全用 are。
例如:I am a student.我是一名学生。
You are a teacher.你是一位老师。
He is my brother.他是我的弟弟。
2. 拓展:除了人称代词,普通名词作主语时也遵循 “单数用 is,复数用 are” 的规则,
例如:The apple is red.这个苹果是红色的。
The apples are red.这些苹果是红色的。
二、be动词的3种基本句式
1. 肯定句:主语 + be 动词 + 表语(名词 / 形容词 / 地点等)
例:She is happy.她很开心。
2. 否定句:主语 + be 动词 + not + 表语
直接在be 动词后加not即可,am not不能缩写,is not=isn’t,are not=aren’t。
例:I am not late.我没有迟到。
It isn’t a cat.它不是一只猫。
We aren’t in the classroom.我们不在教室里。
3. 一般疑问句:Be 动词 + 主语 + 表语?
把 be 动词提到句首,句尾加问号,回答用Yes或No。
例:—Are you a student?你是一名学生吗? —Yes, I am. / No, I am not.
【大显身手】
一、用be动词的适当形式填空。
1.This our new classmate. 2.Mr Black a teacher.
3.I from China. 4.Lucy and Lily sisters.
5.How you, Jane? 6.Who this woman?
二、根据图片提示,回答下列问题。
1.—How old is she?
—
2.—Where are you from, Peter?
—
3.—What colour is Alice's bag?
—
4.—Who are they?
—
考点二:人称代词与物主代词
He's from Canada.
She's our new neighbour, Amy.
一、人称代词和物主代词:

it (is)它(是)
it它

they (are)她/它/他们(是)
them她/它/他们
their她/它/他们的
theirs她/它/他们的
二、形容词性物主代词的用法
概念:形容词性物主代词是具有形容词性质的代词,用于表示所属关系(即“谁的”),后需接名词使用,不能独立存在,如my(我 的)、your(你的)、his(他的)等。
1.形容词性物主代词后跟名词。
例: my pen我的钢笔 his ruler他的直尺 our teacher 我们的老师
2.不能与冠词a/ an/ the或指示代词this/ that/ these/ those同时使用。
例: This is my a pen./ This is a my pen.(×) This is my pen.(√)
3.和形容词一起修饰名词时的顺序为:
形容词性物主代词+形容词+名词。
例: This is our beautiful school.这是我们美丽的学校。
That's her red pen.那是她的红色钢笔。

3.That is (you/your) pen.
4.Do (you/your) like apples?
5.Look! This is (I/me).
6.Linda is (us/our) new neighbour.
考点三:特殊疑问句(询问姓名、来自哪里、身份)
定义:以疑问词开头的疑问句叫特殊疑问句。特殊疑问句的基本结构是“疑问词+一般疑问句?”。
1. 常见的疑问代词:what(什么)、who(谁)、whose(谁的)、which(哪个,在一定范围内选择);
2. 疑问副词:when(询问时间)、where(询问地点)、how(询问怎么样)、why(询问原因)。
特殊疑问句的句型结构:特殊疑问词+一般疑问句(be/助动词/情态动词+主语+谓语)?回答特殊疑问句时,不能用yes/no,须根据所提出的问题作出具体的回答。
例:—What's this?这是什么?
—It's a tiger.这是一只老虎。
1. 询问姓名的句型:—What's your/ her/ his name?
—My/ Her/ His name is +人名。
例:—What's her name?她叫什么名字?
—Her name is Li Ping.她叫李萍。
2. 询问来自哪里的句型:—Where+ be动词+主语+ from?
—主语+ be动词+ from+国家/城市。
Where为疑问副词,意为“在哪里”,用于询问地点,回答时根据实际情况回答地点。
例:—Where are you from?你来自哪里? —I'm from China.我来自中国。
—Where is he from?他来自哪里? —He is from Henan, China. 他来自中国河南。
3. 询问远处某人身份的句型:—Who's that+某人(man/ woman/ boy/ girl...)?
—He's/ She's +身份(my mother/ friend...).
例:—Who's that man?那个男人是谁? —He's my father.他是我父亲。
