含be动词的一般疑问句的结构及其答语
一般疑问句是在句子中用提问的方式提供一些信息，要求对方用 Yes 或 N 回答的疑问句。朗读一般疑问句时用升调，对其回答时用降调。本单元我们学习的是含有be动词的一般疑问句。
含be动词的肯定句变一般疑问句，可采用“一提、二变、三问号”的方法。一提：指的是将be动词提到句首， 且首字母大写。二变： 把原主语的首字母变成小写； 如果原主语为第一人称， 则应把第一人称变为第二人称， be动词也要作出相应的变化； 如果有形容词物主代词my， 也应改为yur。三问号：将句末的标点符号改为问号。
Is she a teacher?
Are yu Tny?
Are thse yur pens?
Is this her bk?
含be动词的肯定句变一般疑问句
表示所有关系的代词叫作物主代词。物主代词分为形容词性物主代词和名词性物主代词两种。
1）形容词性物主代词在句中作定语， 修饰名词2）名词性物主代词相当于“形容词性物主代词+名词”，其后不能再加名词。3）名词性物主代词在句中可作主语、宾语、表语等。作主语时，谓语动词的单复数形式由名词性物主代词所指代的名词的数来决定。
This is my ruler. Hers is in the schlbag. 这是我的尺子。她的在书包里。
（形容词性物主代词my修饰名词ruler）（名词性物主代词Hers=Her ruler后面不能再加名词，且后面的be动词用is。）
1. —I can’t find my pencil. May I use _______? —Of curse. A. yu B. yurs C. yur2. ______ bike is new. A. She B. He C. His 3. My rm is big. ______ is small. A. Her B. Hers C. She
Ⅱ.找出句中错误的一项并改正
1. It’s hers pen. ( ) ____________________ A B C 2. Is this yur bks? ( ) ____________________ A B C D3. Yes, it is. It’s my. ( ) ____________________ A B C D
将 hers 改为 her

1. This is my pencil.（改为一般疑问句） ______________________________2. Are these yur pens? （作否定回答） ______________________________3. That is my schlbag. （同义句） ______________________________
Is this yur pen?
