请总结含be动词的一般疑问句结构和简略回答。
一般疑问句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。
1) 结构：Be动词(am/is/are)+主语+其他?（Be动词要和主语的人称和数保持一致。）2) 肯定回答：Yes, 主语+be动词(am/is/are). 主语和be动词不能缩写。3) 否定回答：N, 主语+be动词(am/is/are)+nt. 通常is、 are和nt要缩写， 但am和nt不能缩写。4)如果一般疑问句主语是this、that、these或thse，回答时用it指代this或that；用they指代these或thse。
—Is this yur pen? 这是你的钢笔吗？ —Yes, it is. 是的，它是。
—Are these yur bks? 这些是你的书吗？ —N, they aren’t. 不，它们不是。
含be动词的肯定句变一般疑问句，可以采用“一提、二变、三问号”的方法。一提：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； 如果原主语是第一人称，则应把第一人称变为第二人称， be动词也作相应变化；如果有形容词性物主代词my，也应改为yur。三问号：将句末的句点改为问号。
He is a student. (改为一般疑问句)
Is he a student?
I am Li Lei. (改为一般疑问句)
Are yu Li Lei? (第一人称变为第二人称)
These are my bks. (改为一般疑问句)
Are these yur bk? (my变为yur)
his schlbag
请找出所有的物主代词，并解释其含义。
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”，其后不能再接名词。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 dictinary. His is n the desk. 这是我的词典。他的（词典）在书包里。（指代His dictinary, 故be 动词用is）
—Are these his bks? 这些是他的书吗？ —N, his are in the schlbag. 不，他的（书）在书包里。（指代his bks, 故be 动词用are）
形容词性能力差，自己不能来当家。句子当中作定语，身后定把名词加。物主代词名词性，相当名词可单用。his、its无变化，my和mine要牢记。其余变形规律化，变形后加-s尾巴。
3a Cmplete the questins and answers abut each picture.
一般疑问句主语是this/that/these/thse，回答时用it指代this/that；用they指代these/thse。
