二、句型转换 1.This is my mother. 1）变否定句
That’s = that is who’re = who are who’s = who is they’re = they are
Explanation
1. mother, father 用于比较正式的场合, 或 向别人介绍自己的父母时使用。如:
David, this is my mother. 大卫, 这是我妈妈。
其中，一般疑问句可分为三种类型：含Be型，含情态动词型和含助动词型， 将陈述句改为一般疑问句只需将Be/助动词/情态动词提前 eg. He is Jack. Is he Jack?
其中，特殊疑问句因为所含特殊疑问词的不同也有几种类型：
What/Who/Where/When/Why等，所以特殊疑问句一般也叫做Wh-疑问句
Grammar Focus 语法焦点
This is my friend Jane. These are my brothers.
Who’s she? Who’s he? Who’re they?
That’s my grandfather. Those are my parents.
She’s my sister. He’s my brother. They’re my grandparents.
Is he Jwachko? 本句用于询问人的身份，所以Jack用特殊
Who is he?
疑问词who代替并提到句子最前面
