探究语法规律
探究一：指示代词用法
Grammar
Focus
1.指示代词
表示“这个”“那个”“这些”“那些”等指示概念的词,叫指示代词。如this，that,
these,
those等。英语中指示代词的用法同汉语中的情况相似,
this(这个)和these(这些)一般用来指较近的人或事物,
that(那个)和those(那些)则指较远的人或事物。
2.
学习指示代词,
应注意以下几点:
①this与is,
these与are没有缩写形式。This
is
a
Chinese
car.
这是一辆国产轿车。
②指示代词作主语指物并用于问句中
时，回答一般用it代替this和that，they代替these和those.
3.
指示代词在句子中的用法
在句子中指示代词可以充当主语、定语、宾语或表语。例如：
This
is
a
pear.(作主语)
这是一个梨。
These
video
clips
are
very
interesting
and
those
ones
are
not.
(作定语)
这些光碟很有趣,
那些没意思。
I
like
this
very
much.(作宾语)
我很喜欢这个。
Oh,
it’s
not
that.(作表语)
哦,
不是那个。
Is
this
your
pencil?
Yes,
it
is.
It’s
mine.
/
No,
it
isn’t.
It’s
hers.
Is
this
his
green
pen?
Yes,
it
is
/
No,
it
isn’t.
The
blue
pen
is
his.
Is
that
your
schoolbag?
Yes,
it
is.
/
No,
it
isn’t.
It’s
his.
Are
these
your
books?
Yes,
they
are.
/
No,
they
aren’t.
They’re
hers.
Are
those
her
keys?
Yes,
they
are.
/
No,
they
aren’t.
They’re
mine.
探究语法规律
探究二：单数复数的用法
Grammar
Focus
this(这个)、that(那个)，表示一个物体，是单数概念，后面的名词用单数
形式(pencil,
pen,
schoolbag),
回答时也用单数形式(it
is,
it
isn’t;
It’s
…)
2.
these(这些)、those(那些)，表示一些物体，是复数概念，后面的名词用
复数形式(books,
keys),
回答时也用复数形式(they
are,
they
aren’t,
They’re)。

Is

it

探究三：be动词的一般疑问句
Grammar
Focus
be动词引导的一般疑问句及回答
含有be动词的一般疑问句，即“be
动词+主语（指示代词）+其他？”;
当主语是指示代词this/that,作省略回答时，要用it代替；
当主语是指示代词these/those,作简略回答时，要用they代替;
第一人称改为一般疑问句要进行人称转换。
e.
g.
This
is
my
book.
（改为一般疑问句）
Is
this
your
book?
一般疑问句是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。朗读一般疑问句用升调，其简略答语用降调。
由
be
动词（am，is，are）引导的疑问句结构是：
“be
+
主语
+
其他部分？”
含有
be
动词的一般疑问句
Is
that
your
bike?
↗
那是你的自行车吗？
Are

否定回答：No,
