译林版英语三年级上册 Unit 5 She's my mother 核心语法精讲精练
第一部分:核心语法梳理
本单元围绕“家庭成员”主题展开,核心是掌握用Who's...?询问人物身份及其答句,以及介绍家人的相关表达。重点语法知识点有以下四个方面:
语法一:Who's...? 询问“某人是谁”的特殊疑问句
基本用法
“Who is...?”(缩写为Who's...?)是询问某人是谁的特殊疑问句。who是特殊疑问词,意为“谁”,后面可接人称代词(he/she)或可数名词单数短语(the girl, that boy, your sister等)。
句型结构
问句:Who's + 被询问的人(he/she/that girl...)? —— 意思是“……是谁?”
答句:根据性别回答——男性用He is...,女性用She is...;对象是照片中的人物或不清楚性别的婴儿时,也可用It is...。
举例:
—Who's she? 她是谁?
—She's my mum. She's great. 她是我的妈妈。她很棒。
—Who's he? 他是谁?—He's my brother. 他是我的哥哥。
使用要点
回答时要注意人称对应:问句用Who's she?,答句就要用She's...;问句用Who's he?,答句就要用He's...。
语法二:介绍家人的句型——This is... / He's / She's...
This is...用于介绍
“This is + 家庭成员”用于向别人介绍自己的家人。
例如:This is my mother. 这是我的妈妈。
He's / She's 用于说明关系
在回答Who's...?问句时,用“He's / She's + my + 家庭成员”来具体说明身份。
举例:
—Who's she? 她是谁?—She's my sister. 她是我的姐姐。
—Who's he? 他是谁?—He's my father. 他是我的爸爸。
语法三:look与look at的用法区别
这是本单元的核心易错点,请特别注意区分。
look(不及物动词)——后面不能接宾语,通常单独使用,用于引起对方注意。例如:Look! This is my grandpa. 看!这是我的爷爷。
look at(look + 介词at)——后面可以接宾语,表示“看具体的人或事物”。例如:Look at the baby. 看这个小宝宝。
举例对比:
- Look! The girl is my sister. (看!那个女孩是我的姐姐。)——单独使用,引起注意
- Look at my new skirt. (看我的新裙子。)——后面接了“my new skirt”这个宾语
易错提醒:当表示“看某人/某物”时,一定不能省略at。不能说Look my book,要说Look at my book。
语法四:Good evening. 晚上见面时的问候语
“Good evening.”是人们晚上见面打招呼的常用语,一般用于下午6点到晚上10点之间的时段。回答时直接用“Good evening.”即可。
注意区分:
- Good evening.——晚上见面时的问候语
- Good night.——晚上道别或即将就寝时的祝福语,意为“晚安”
易错提醒:
- Who's...?的问与答:问谁答谁——问She答She's,问He答He's,一定要对应好。
- look vs look at:没有“看什么”时用look,有“看什么”时用look at,不能混用。
-Good evening vs Good night:见面时说Good evening,道别或睡觉前说Good night。
-This is...介绍人:介绍家人用This is...,介绍自己用I'm...,不要混淆。
