【考点一】家人称谓的辨析与使用 【考点二】询问他人年龄的句型
【考点三】be动词在家人相关句型中的应用 【考点四】This/That/These/Those 在家人介绍中的使用
考点一:家人称谓的辨析与使用
1. 核心考点:区分不同家人的英文称谓,明确“男性/女性”“长辈/同辈”对应的词汇,避免混淆。
男性长辈:grandfather (grandpa)、father (dad)、uncle
女性长辈:grandmother (grandma)、mother (mum)、aunt
同辈男性:brother、cousin(堂/表兄弟)
同辈女性:sister、cousin(堂/表姐妹)
2. 用法解析:称谓前常加形容词性物主代词“my/your/his/her”,如“my father”(我的爸爸)、“her aunt”(她的姑姑)。
3. 常见场景:向他人介绍自己的家人时使用,例如“Hi, Miss Gao. This is my father.”(高老师您好,这是我的爸爸。)
【大显身手】
一、单项选择题。
1. —______ is your mother?
—She is over there.
A. Who B. What C. Where D. How old
2. —How old ______ your brother?
—He ______ seven years old.
A. is; is B. are; is C. is; are D. are; are
3. This ______ my aunt. She ______ a teacher.
A. is; is B. are; is C. is; are D. are; are
4. —Nice to meet you, Uncle Li.
—______
A. Goodbye! B. Nice to meet you too. C. How old are you? D. I am fine.
5. Those ______ my cousins. ______ are in Class 3.
A. is; They B. are; He C. are; They D. is; She
考点二:How old 引导的年龄询问句型
—How old are you?
—I’m eight years old.
1. 核心结构:
- 提问:How old + be动词 (am/is/are) + 主语?
- 回答:主语 + be动词 (am/is/are) + 数字 + years old.
2. 用法细节:
主语是第一人称“I”时,be动词用“am”,如“How old am I?”(我几岁了?)
主语是第三人称单数(he/she/单数人名)时,be动词用“is”,如“How old is Li Ming?”(李明几岁了?)
主语是复数(they/we/复数人名)时,be动词用“are”,如“How old are they?”(他们几岁了?)
3. 注意事项:“years old”可省略,直接说“I am eight.”(我八岁了),口语中更简洁。
【大显身手】
一、判断并改错(对打“√”,错打“×”,并在横线上写出正确句子)
1. He is I uncle.( )__________
2. How old is you?( )__________
3. These is my grandmother.( )__________
4. My sister are ten years old.( )__________
5. This are my father.( )__________
二、按照要求完成句子。
(1)I am eight years old.(对划线部分提问)
(2)How old are you?(根据自己实际情况写答案)
(3) 你几岁了?(把这句话翻译成英文)
________ __________ _________ you?
考点三:be动词的形式和用法
be动词的核心形式:原形为be,在句中根据人称、数和时态变化为 am, is, are, was, were, been, being 七种具体形式。本单元出现的是最基础的is,am,are。
1.基础形式(如表)
2.本单元be动词在家人相关句型中的应用。
基础形式回顾(结合Unit 1,聚焦本单元高频用法):
人称/数 对应be动词形式 例句(家人相关)
第一人称单数(I) am I am Li Wenbo’s sister.(我是李文博的妹妹。)
第三人称单数(he/she/单数称谓) is He is my uncle.(他是我的叔叔。)
第二人称(you)/复数(they/复数称谓) are You are my cousin.(你是我的表妹。) They are my grandparents.(他们是我的祖父母。)
2. 易错点:介绍单数家人时,易误将“is”写成“are”,如错误表达“This is my mothers.”(应为“This is my mother.”);介绍复数家人时,易漏用“are”,如错误表达“They my brothers.”(应为“They are my brothers.”)。
【记忆口诀】
我用am,你有are,is 跟着他她它。
【大显身手】
一、选择题。
( )1.How old _______you?
A. am B. is C.Is D. are
( )2.What______your name?
A.is B. am C. are D. Is

( )4. Dad, this_______my classmate. He_______Li Wenbo.
A.are; is B. am ;is C. is; is D. Are; is
( )5. They ______my good friends. We often play together after school.

二、根据提示补全句子。
1. —______ ______ is your cousin?(你表妹几岁了?)

2. —______ ______ this?(这是谁?)
—______ ______ my aunt.(这是我的姑姑。)
3. —How are you, Grandma?
—I ______ ______, ______ ______.(我很好,谢谢你。)
4. Those ______ my ______ and ______.(那些是我的爷爷和奶奶。)
考点四:This/That/These/Those 在家人介绍中的使用
1. 核心区别:
- 近指单数:This(这个),用于介绍身边的单个家人,如“This is my mum.”(这是我的妈妈。)
- 远指单数:That(那个),用于介绍远处的单个家人,如“That is my grandpa.”(那个是我的爷爷。)
- 近指复数:These(这些),用于介绍身边的多个家人,如“These are my sisters.”(这些是我的姐姐们。)
- 远指复数:Those(那些),用于介绍远处的多个家人,如“Those are my uncles.”(那些是我的叔叔们。)
2. 搭配规则:This/That 后接be动词“is”,These/Those 后接be动词“are”,不可混淆。
【大显身手】
1、 选择正确的单词填空。
1. This________(is/are)my father .He________(am/is)a teacher.

4. That _______is my English teacher. He_____tall and thin.
5. These apples_______red. That one ______little green.
二、情景对话匹配(将A栏的句子与B栏的答句用线连起来)
A栏 B栏
1. Who is that woman? A. I am nine.
2. How old are you? B. She is my mother.
3. Nice to meet you, Aunt Wang. C. They are my brothers.
4. Who are those boys? D. Nice to meet you too.
