be动词的一般疑问句Ⅱ：
在第一单元我们已经初步学习了含有be动词的一般疑问句，即：“Be动词＋主语(人称代词)＋其他？”。本单元重点学习be动词引导的一般疑问句，其结构为：“Be动词＋主语(指示代词)＋其他？”。当主语是指示代词this/that，作简略回答时，要用it代替；当主语是指示代词these/those，作简略回答时，要用they代替。
如：—Is this his book？这是他的书吗？
—Yes，it is.是，它是。
—Are these your books？这些是你的书吗？
—No，they aren't.不，它们不是。
【注意】第一人称要进行人称转换。
如：This is my pencil.这是我的铅笔。(改为一般疑问句)
→Is this your pencil？这是你的铅笔吗？
名词性物主代词：
在英语中，物主代词是表示所有关系的代词，分为形容词性物主代词(第一单元已学过)和名词性物主代词(本单元所讲)两种。
概念：名词性物主代词也是用来表示所有关系的代词，有人称和数的变化。
第一人称 第二人称 第三人称
单数 mine yours his/hers/its
复数 ours yours theirs
用法：①名词性物主代词在句中能单独使用，后面不能接名词，其作用相当于一个名词，通常在句中作主语、宾语或表语。
②名词性物主代词在作主语时，谓语动词的数应随所指者的数来定。
如：This red pencil is mine.Hers is black.(Hers＝her pencil)这支红色的铅笔是我的，她的(铅笔)是黑色的。
These books are his.Yours are over there.(Yours＝Your books)这些书是他的，你的(书)在那边。
与形容词性物主代词之间的关系：
名词性物主代词＝相应的形容词性物主代词＋名词
如：This is my bike.That is yours.(yours＝your bike)这是我的自行车，那是你的(自行车)。
结构：“be + 主语 + 其他部分？”
意思：……吗？
答句：Yes/No开头回答。
注意：肯定回答不可以缩写
朗读：一般疑问句用升调
例如：Is it your schoolbag
Yes, it is./ No,it isn’t.
Are these his dictionaries
Yes, they are./ No, they aren’t.
含有 be 动词的一般疑问句
be动词引导的一般疑问句构成法则：
1、一提→be动词提到句首
2、二变→大小写、人称
3、三问号→句子末尾加问号
be的用法口诀：
我用am，你用are, is跟着他、她、它。
单数is，复数are，勿忘be的三变化。
变疑问，往前提，句末问号莫丢弃。
变否定，更容易，be后not莫忘记。
疑问否定任你变，句首大写莫迟疑。
1. That is his schoolbag. (变为一般疑问句)
__ ____ his schoolbag (作肯定及否定回答)
Yes, __ __. / No, __ _____.
2. These are her erasers. (变为一般疑问句)
____ _____ her erasers (作肯定及否定回答)
Yes, _____ ____. / No, ____ _______.
