知识梳理
1. 一般疑问句
本单元主要句型是：“Is this/that… ”“Are these/those… ”它们都是一般疑问句，他们被用来确认物主关系。
Is this/that… 主要用来确认单数名词的物主关系。回答为：Yes，it is.或No，it isn't.
Are these/those… 主要用来确认复数名词的物主关系。回答为：Yes，they are.或No，they aren't.
2. 物主代词
表示所有关系的代词称为物主代词，物主代词有形容词性物主代词和名词性物主代词。英语中主要有下面这些物主代词。
人称 单数 复数
形容词性 名词性 形容词性 名词性
第一人称 my mine our ours
第二人称 your yours your yours
第三人称 his
her
its his
hers
its their theirs
(注：目前已学过my，mine，your，yours，his，his，hers，her这8个物主代词，其余的我们将在后面学到。)
2.1 形容词性物主代词相当于形容词，只能用于名词前作定语。eg：my book我的书　his rulers他的尺子
【注意】当名词前有形容词性物主代词时，就不能再用
冠词(a、an)或指示代词。
2.2 名词性物主代词具有名词的性质，可以在句中作主语、宾语和表语。名词性物主代词不能和名词连用，因为名词性物主代词相当于形容词性物主代词＋名词。
eg：—Is that pen hers？那钢笔是她的吗？
—No.Her pen is blue.不，她的钢笔是蓝色的。
【歌诀助记】
物主代词两类型，一曰“名”来一曰“形”。
形容词性只作定，句中运用后带“名”。
名词性作主宾表，后面名词不能要。
以上两点若记牢，运用时候错不了。

Is ____ his ruler
Are _____ my pencils

Is ____ your book
