3.Do

anything

【词汇解读】
valuable形容词，意为“贵重的；很有用的；宝贵的”，在句中可用作定语，也可用作表语。用作表语时，可与介词to连用，常用短语be
valuable
to
sb.“对某人来说很有价值”。anything
valuable
一些贵重的东西。形容词valuable修饰不定代词anything要后置。当形容词修饰不定代词(something,
anything,
nothing等)时，形容词应放在不定代词的后面。
【活学活用】1)
这一经历对我很有用。
2）

pick
up意为“拿起；捡起”。它是由“动词+副词”
构成的短语，当其宾语是名词时，该名词即可位于up之后，
也可位于pick与up
之间；当其宾语是代词时，该代词必须
位于pick
与up之间。另外pick
up
还有（开车）接人;
(偶然)
学会的意思。
【活学活用】
1)
我的尺子在你的桌子下面，能请你帮我捡起来吗？
2）
把纸捡起来然后丢在垃圾桶里。

it
up
for
me

and
put
it

the

must
have
picked
it
up是“must+have+过去分词”的结构，
must在此处表示推测,
意为“一定”。当情态动词后接have
done时,
表达对过去的事情进行推测,
故must
have
done
something表示“过去一定做过了”这样的意思。

语法特征
1.情态动词不能表示正在发生或已经发生的事情，只表示期待或估计某事的发生。
2.情态动词除ought
和have
外，后面只能接不带to
的不定式。
3.情态动词没有人称、数的变化，即情态动词第三人称单数不加-s。
4.情态动词没有非谓语形式，即没有不定式、分词等形式。
情态动词定义
表示可能、怀疑、允诺、愿望、义务、必要、猜测等的动词就是情态动词。
语法重点：情态动词表推测
英语中表示推测的情态动词主要有
must，can，could，may，might等,它们可以对过去、现在或将来的情况作出语气强弱不同的推测。
确定的推测
含义
不确定的推测(可能性依次减弱)
含义
肯定句
must
一定；必定
can＞could＞may＞might
可能
否定句
can’t＞couldn’t
不可能
may
not＞might
not
不大
可能
can和could也可以用于疑问句中表示推测。
情态动词表示推测有以下几种结构表示:
情态动词+
do
/
be
(表示对现在或将来的动作或状态推测)
eg:
—Do
you
know
where
she
is
now 你知道她现在在哪吗？—I
think
she
might
travel
in
Beijing.
我想她可能在北京旅行。
be
doing
(表示对正在发生的事情推测)
eg:
At
this
moment,
my
father
can’t
be
working
in
the
office.
这个时候我爸爸不可能正在办公室工作。
情态动词+
have
done
(表示对过去发生的事情推测)
eg:
The
road
is
wet.
It
must
have
rained
last
night.路是湿的，昨晚肯定下过雨了。
have
been
doing(表示对过去正在进行的事情推测)
eg:
Your
mother
must
have
been
looking
for
you
at
that
moment.你妈妈那个时候肯定正在找你。
must
具体用法
must
表示必须要做的事，意为“必须，应该”。must一般问句的否定回答用needn’t或don’t
have
to
,
而不用mustn’t，
mustn’t意为“不可以，不能”，表示禁止，不许可。另外，must还可表示有把握的推测，意为“一定、肯定”。must的过去式还是must。
在回答以must开头的一般疑问句时，否定式需用need
not
(needn’t)，表示“不必”的意思。
eg：—
Must
we
hand
in
our
exercises
today
—
Yes,
you
must.
(
No,
you
needn’t)
must意为“一定；准是”。表示说话人对事物的推测可能性的程度非常大。
①“must
be
+表语”意为“一定……”，表示对现在情况的推测。eg:
I
can’t
understand
them.
They
must
be
foreigners.
②“must
be+现在分词”意为“一定正在……”，表示对说话瞬间情况的推测。
eg:
She
must
be
cooking
now
because
I
can
smell
something
delicious.
③“must
have
+过去分词”意为“一定已经……”，表示对过去情况的推测。
eg:
I
can’t
find
my
keys
.I
must
have
left
them
at
home.
may
may表示允许、也许，意为“也许；可能；可以”，语气不太可能。may
not，意为“也许不”。对may的一般问句的回答：
肯定回答一般是：Yes,
please./
Certainly./
Sure等
否定回答一般是：Please
don’t./No,
you
can’t/mustn’t.
might是may的过去式，与may用法类似，语气比may弱，表示推测的可能性更小，常用于肯定句和否定句中，不用于疑问句中。
常见句型为：“may
be
+表语”意为“有可能……”，表示对现在的可能推测。
eg:
He
may
be
angry
because
he
looks
unhappy.
can
can
可表示能力、允许、可能性、怀疑猜测，意为“可以，会，能”；can’t意为“不会，不能，不可以”，还有“不可能”之意。could为can的过去式，用法与can类似，常用于过去时态中；could还可用于现在时态中表示委婉客气，相当于can；could也可表示惊讶怀疑，不相信。can’t和couldn’t
一般用于否定句和疑问句中。
eg：He
couldn’t
be
a
thief.
can表示推测时，常用于否定句、疑问句中，can’t意为“不可能；应该不是”。
常用句型为：“can/can’t
be
+表语”意为“（不）可能……”，表示对现在情况的推测。
eg:
That
can’t
be
Maria,
because
she’s
in
hospital.
There’s
someone
outside.
Who
can
it
be
could/might:如果表示推测的把握性不是很大时，用could或might。它们常用于肯定句或疑问句中，意为“也许；可能”。
eg:
He
might
be
doing
his
homework
now.
Could
the
news
be
true

dictionary
________
belong
to
Sam.You
can
see
his
name
on
it.
A．can
B．must
C．need
D．would
句意：这本字典一定是萨姆的。你可以在上面看到他的名字。
考查情态动词辨析。can可能，表推测；must一定，表肯定推测；need需要，指有必要；would将要，用于表示意愿。根据下文You
can
see
his
name
on
it.可知是肯定推测，故选B。
2.

next
room？
It____be
Lisa，
but
I'm
not

A．must
B．may
C．need
句意：谁正在隔壁房间唱歌？
可能是Lisa，但我不确定。
A.
must一定是；B.
may可能是；C.
need需要。由I'm

A.might
B.

C.

句意“那个不可能是外星人，没有这样的东西”。A.可能（表示推测）；B.一定是（表示肯定的推测）；C.一定不是（表示否定的推测）。根据there’s
no
such
thing!“没有这样的东西”可知，表示否定的推测，即“那一定不是外星人”，故选C。
