语法拓展
一、be动词引导的一般疑问句及回答
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（指示代词）+其他？”。当主语是指示代词this/that,作省略回答时，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。
e.g.:—Is that his pen —Yes,it is.
—Are these your pencils —No,they aren't.
注意：第一人称改为一般疑问句要进行人称转换。
e.g.:This is my pencil.（改为一般疑问句）
正：Is this your pencil 误：Is this my pencil
二、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
2.用法：(1)名词性物主代词在句中可单独使用，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。有时为了避免重复用名词，而用名词性物主代词来代替形容词性物主代词加名词形式。
（2）名词性物主代词作主语时，谓语动词的单复应随所指物品的单复来定。
e.g.:Those rulers are his.Yours are red.
3.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
e.g.:This is my bike.That is yours.(yours=your bike)
如：my red pen我的红色钢笔
