(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.
2.一般疑问句
(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。

形容词性物主代词 my your his her its our your their
名词性物主代词 mine yours his hers its ours yours theirs
含义 我的 你的 他的 她的 它的 我们的 你们的 他/她/它们的
3.物主代词的分类
名词性物主代词
物主代词分形容词性和名词性两类，第一课中已经提及。我们将借助形容词性物主代词来解释说明名词性物主代词
以上是两类物主代词的汇总，我们将通过例子说明：
单数 复数 一 二 三 一 二 三
形容词性 my your his/her/its our your their
名词性 mine your his/hers/its ours yours theirs
含义 我的 你，您的 他/她/它的 我们的 你们的 他/她/它们的
数
人称
类别
用法：
1）名词性物主代词在句中独立使用，相当于”名词性物主代词 = 形容词性物主代词+前文提到的物品“，后面不再加名词。
2）名词性物主代词在句中可作主语、表语或宾语。用作主语时，谓语动词的数应随所指对象的数而定。
ex：1 -Is this ruler yours or hers
-It's mine. Hers is in her bag.
（Hers = her ruler, 所以be动词选择is）
2 -Whose books are these
-They are his. Yours are over there.
（yours =your books, 所以be动词选择are）
This is my pencil.
This is mine.

This is her schoolbag.
This is hers.
This is your dictionary.
This is yours.
e.g. This is your ruler. It’s not my ruler.
(= This ruler is _____. It’s not _____.)
这是你的尺子，它不是我的。
Those aren’t his books. They’re her books.
(= Those books aren’t ____. They’re _____. )
那些书不是他的。它们是她的。
yours
mine
his
hers
4.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？
