人教版英语三年级上册 Unit 2 Different families 知识清单 第一部分：知识清单 一、单元主题概述 本单元围绕"不同的家庭"这一主题展开，主要学习如何用英语介绍自己的家庭成员、询问和确认他人的家庭成员，以及描述家庭的大小。学生通过本单元的学习，能够理解"家庭各有不同，但家庭成员之间的爱是相同的"这一核心理念。 二、重点词汇 1.核心家庭成员称呼 father 父亲；爸爸（正式用语） dad （口语）爸爸；爹爹 mother 母亲；妈妈（正式用语） mum （口语）妈妈 grandfather （外）祖父；爷爷；姥爷；外公 grandma （口语）奶奶；姥姥 grandmother （外）祖母；奶奶；姥姥；外婆 grandpa （口语）爷爷；姥爷 brother 哥；弟 sister 姐；妹 cousin 堂（表）兄弟；堂（表）姐妹 uncle 伯父；叔父；舅父；姑父；姨父 aunt 伯母；婶母；舅母；姑母；姨母 baby 婴儿 me 我（宾格） 2.描述性词汇 big 大的 small 小的 different 不同的 same 相同的 some 一些 3.实用短语 my family 我的家庭 a big family 一个大家庭 a small family 一个小家庭 family photo 家庭照片 family tree 家庭树 play with 和……玩 share with 和……分享 talk with 和……交谈 三、文化小贴士 中西方家庭称呼的差异：中国人所说的"家庭"通常包括祖父母、叔伯等在内的大家庭（extended family），而西方人的家庭更多指自己的"核心家庭"（nuclear family）。中文会将爸爸的爸爸叫爷爷，妈妈的爸爸叫外公，而英语都用grandfather来表示。 四、核心句型 1. 介绍家庭成员 This is my + 家庭成员称呼. 例句：This is my father. 这是我的爸爸。 This is my sister. 这是我的姐姐/妹妹。 也可以用：He/She is my + 家庭成员称呼. 例句：He is my grandpa. 他是我的爷爷。 She is my mum. 她是我的妈妈。 2. 询问对方家庭成员 —Who is he/she? —He/She is my + 家庭成员称呼. 例句：—Who is she? —She is my mother. —Is this/that your + 家庭成员称呼? —Yes, it is. / No, it isn't. 例句：—Is this your sister? 这是你的姐姐吗？ —No, it's my cousin. 不，她是我的表姐。 —Is that your brother? 那是你弟弟吗？ —Yes, it is. 是的，他是。 3. 描述家庭大小 My family is big/small. 我的家庭大/小。 My family has + 数字 + people. 我家有……口人。 How many people are there in your family? 你家有几口人？ 4. 描述家庭成员构成 I have a/an + 家庭成员. 例句：I have a brother, a baby sister, a cousin... 我有一个哥哥、一个婴儿小妹妹、一个堂弟…… I have two cousins. 我有两个堂兄弟。 五、核心语法 1. 形容词性物主代词 my my（我的）后接名词，表示"我的……"。 例句：my mother（我的妈妈）、my family（我的家庭） 注意：my后面的名词不需要加冠词a/an/the。 2. 人称代词主格与宾格 he（他）—— 主格，作主语 she（她）—— 主格，作主语 me（我）—— 宾格，作宾语 例句：She is my sister. （she作主语） This is me. （me作宾语） 3. 一般疑问句 Is this/that... 由be动词引导的一般疑问句，用于确认某人的身份。 —Is this/that + 某人？ —Yes, it is. / No, it isn't. this指距离近的人或物，that指距离较远的人或物。 4. family的用法 family表示"家庭"或"家人"，是集合名词。若视为整体，表示一个家庭，具有单数意义（My family is big.）；若逐个考虑家庭成员，则具有复数意义（My family are all tall.）。 5. some的用法 some意为"一些"，既可修饰可数名词复数（some books），也可修饰不可数名词（some water）。 例句：Some families are small. Some are big. 一些家庭小，一些家庭大。 六、重点背默句子 1. This is my family. 这是我的家庭。 2. This is my father. He is tall and strong. 这是我的爸爸。他又高又壮。 3. How many people are there in your family? 你家有几口人？ 4. Is that your aunt? No, it isn't. It's my teacher. 那是你的阿姨吗？不，不是。她是我的老师。 5. My family is big. I have a brother, a baby sister and a cousin. 我的家庭很大。我有一个哥哥、一个婴儿小妹妹和一个堂弟。 6. This is my friend, Sarah Miller. 这是我的朋友，萨拉·米勒。 第二部分：配套暑假预习练习 一、根据汉语意思，选单词。（10分） 根据汉语意思，选择正确的单词。 ( ) 1. 爸爸 A. mum B. dad C. sister ( ) 2. 奶奶 A. grandpa B. grandma C. brother ( ) 3. 堂兄弟 A. cousin B. uncle C. aunt ( ) 4. 婴儿 A. baby B. big C. small ( ) 5. 家庭 A. family B. father C. mother ( ) 6. 姐姐 A. brother B. sister C. me ( ) 7. 叔叔 A. aunt B. uncle C. cousin ( ) 8. 妈妈 A. mum B. dad C. grandpa ( ) 9. 爷爷 A. grandpa B. grandma C. mother ( ) 10. 我（宾格） A.
