Are those her keys Yes, they are. / No, they aren’t. They’re mine.
it’s ＝ it is isn’t＝is not aren’t＝are not
(1)一般疑问句的概念：能用yes或 no回答的问句就叫一般疑问句。
(2)含有be动词的陈述句变一般疑问句的方法：
※将be动词提至句首
※将句末标点改为问号
※将第一人称变为第二人称，即 I 由 you替换；my 由 your 替换；相应地 am 也变为 are.
Language points
(3)含有be动词的一般疑问句的回答方式：
①肯定回答：Yes, 主语+ be (am,is are). 其中be动词不能与主语缩写。
②否定回答：No, 主语+ be (am, is, are)+not. 其中 be可以与 not 缩写，但 am不能与 not 缩写。
(4)一般疑问句的语调：读一般疑问句用升调 ↑，其简略回答用降调 ↓。
疑问句的主语是第一人称，回答时主语要换成第二人称；疑问句的主语是第二人称，回答时主语要换成第一人称； 疑问句是第三人称，回答时主语不变。

物主代词的分类
Presentation
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 schoolbag. 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。）
物主代词的用法
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。

▲名词所有格
英语中除了用物主代词表示物品所属外，还可用名词所有格来表示。名词所有格常分为三类：
(1)单数名词和不以 s结尾的复数名词的所有格是在该名词的末尾加“'s”。如：Tom's，Mike's，children's，women's。
(2)以 s结尾的复数名词的所有格是在复数名词的末尾直接加“'”。如：teachers' books。
(3)无生命的名词的所有格一般使用of，意为“……的”。如：the key of the door，a photo of my family。
▲缩写对话时要注意this/that与单数名词连用，these/those与复数名词连用。
如：Is this/that your eraser？这个/那个是你的橡皮吗？
Are these/those your erasers？这些/那些是你们的橡皮吗？
