请总结含be动词的一般疑问句结构和简略回答。
Are
these
your
books?
Yes,
they
are./No,
they
aren’t.
They’re
hers.
一般疑问句在句子中用提问的方式提供一些信息，要求对方用
Yes
或
No
回答的疑问句。朗读一般疑问句时用升调，对其回答时用降调。本单元我们学习的是含有be动词的一般疑问句。
语法概述
Presentation
1)
结构：Be动词(am/is/are)+主语+其他?（Be动词要和主语的人称和数保持一致。）
2)
肯定回答：Yes,
主语+be动词(am/is/are).
主语和be动词不能缩写。
3)
否定回答：No,
主语+be动词(am/is/are)+not.
通常is、
are和not要缩写，
但am和not不能缩写。
4)如果一般疑问句主语是this、that、these或those，回答时用it指代this或that；用they指代these或those。
—Is
this
your
pen?
这是你的钢笔吗？
—Yes,
it
is.
是的，它是。
—Are
these
your
books?
这些是你的书吗？
—No,
they
aren’t.
不，它们不是。
不可以缩写成it’s
含be动词的肯定句变一般疑问句，可以采用“一提、二变、三问号”的方法。
一提：be动词提到句首，
且首字母大写。
二变：把原主语的首字母变成小写；
如果原主语是第一人称，则应把第一人称变为第二人称，
be动词也作相应变化；如果有形容词性物主代词my，也应改为your。
三问号：将句末的句点改为问号。
He
is
a
student.
(改为一般疑问句)
Is
he
a
student?
I
am
Li
Lei.
(改为一般疑问句)
Are
you
Li
Lei?
(第一人称变为第二人称)
These
are
my
books.
(改为一般疑问句)
Are
these
your
book?
(my变为your)

your
pencil?

it
is.
It’s
mine./No,
it
isn’t.
It’s
hers.
Is
this
his
green
pen?
Yes,
it
is./No,

The
blue
pen
is
his.
Is

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”，其后不能再接名词。
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
dictionary.
His
is
on
the
desk.
这是我的词典。他的（词典）在书包里。（指代His
dictionary,
故be
动词用is）
—Are
these
his
books?
这些是他的书吗？
—No,
his
are
in
the
schoolbag.
不，他的（书）在书包里。（指代his
books,
故be
动词用are）
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。
