请总结含be动词的一般疑问句结构和简略回答。
Grammar Focus
【句型剖析】
（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.
简单归纳即为：一提二变三替换。
Mary is an English girl .
一般疑问句是：Is Mary an English girl
I am in my classroom.
一般疑问句是：Are you in your classroom
(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。
如：—Is this an ID card —Yes, it is.
—Are you Mr.Smith —No, I’m not.
（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 ↓。
【温馨提示】
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。
—Am I right 我是对的吗
—Yes, you are. 是的, 你是对的。
—/No, you aren’t. 不, 你不对。
—Are you Alan 你是艾伦吗
—Yes, I am. 是的, 我是。—/No, I’m not. 不, 我不是。

请找出所有的物主代词，并解释其含义。
my pencil
her pencil
his pen
his schoolbag
her books
my keys
【知识构建】
表示所有关系的代词叫做物主代词 (Possessive Pronouns) , 也叫人称代词的所有格。物主代词分为形容词性物主代词和名词性物主代词两种。物主代词有人称和数的变化。人称代词与其对应的物主代词见下表:
人 称 形容词性物主代词 名词性物主代词
I my mine
you your (你的) yours
he his his
she her hers
it its its
we our ours
you your (你们的) yours
they their theirs
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。
物主代词的用法
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。）
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。
物主代词用法小记
狗的名字 __________________
the name of the dog
(1) 表示无生命事物的所有关系，用“名词 + of + 名词”结构，表示前者属于后者。
(2) 表示有生命事物的所有关系，在名词其后加’s来表示所属关系，意为“……的”。
例如：安娜的 Anna’s 鲍勃的 Bob’s
名词所有格的构成方法：
一般的单数名词在词尾直接加“’s” Tom’s book 汤姆的书
my uncle’s car 我叔叔的小汽车
以-s结尾的复数名词在词尾加“’” the students’ basketball
学生们的篮球
不规则复数名词在词尾加“’s” Women’s Day 妇女节
Children’s Day 儿童节
