_______________________none
of…没有一个,
全无,
既可以用来指人,也可以指物。none
后常常接of
短语构成“none
of
+
名词/代词”结构。接不可数名词,谓语动词用_____,
接可数名词或者代词宾格复数时,谓语动词用___________都行。None

________been

辨析:
none
no
one
nobody
no
one
和nobody可互用,用于指人,不能与of短语连用,用作单数;none用于指人或物,可以与of短语连用,用作单数或复数,一般用在一定的范围内none
强调的数量,而nobody强调的是人。如果使用How
many提问的话用none,用who提问的话用nobody,
---Who
is
in
the
room?
---Nobody
---How
many
people
are
there
in
the
room?
---None
日常用时只要记住一句话:none既能指人也能指物,nobody只能指人.
None

___________________________________everybody
=

人人,每个人比较:everyone
与every
one
everyone是一个词,只用来指人,等于everybody,在它后面不能跟介词of;every
one是两个词,既可用来指人,也可用来指物,等于each
one,后面可跟介词of。
下面比较一下它们的用法:
A、everyone是不定代词。当表示“每一个、人人”时,它等于everybody,且谓语动词用单数形式,如:
Everyone
is
here.(大家都来了。)
B、every
one表示“人人、每个人”讲时,它也等同于everyone,如:
Every
one
put
on
his
hat等于Everyone
put
on
his
hat.C、every
one表示“每一个(东西、事情)”,这时的one是代词,指代已经明确的东西或事情,以避免重复。D.every
one
可以与of
连用,但是everyone不可以。我们可以说every
one
of
them/us,却不能说everyone
of
them/us.
如:He
ate
every
one
of
the
mooncakes.(他把月饼都吃光了。)
I
know
every
one
of
them.我认识他们当中的每一个人。5.

________________________1.
something
useful
不定代词、副词被形容词修饰时,形容词一般都置于不定代词、副词之后。例如:(1)There
is
nothing
wrong
with
your
eyes.你的眼睛没有问题。(2)I
have
something
important
to
tell
you.
我要告诉你一些重要事
新知识点很多,根据学生掌握进度,再进行.结合例题。
