新课讲解
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。英语中表示推测的情态动词主要有
must,
can,
could,
may,
might等。
定义
新课讲解
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ought和have,后面只能接带to的不定式。
语法特征
新课讲解
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。
新课讲解
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
新课讲解
may表示允许、也许，意为“也许；可能；可以”，语气不太可能。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：No,
you
can’t/mustn’t.
may
新课讲解
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。
新课讲解
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。
must
新课讲解
eg:
—
Must
we
hand
in
our
exercise
book
today?
—
Yes,
you
must.
(
No,
you
needn’t.)
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needn’t，表示“不必”的意思。

Stonehenge

Stonehenge,

Every

n.神秘（的事物）
新课讲解
For
many
years,
historians
believed
Stonehenge
was
a
temple
where
ancient
leaders
tried
to
communicate
with
the
gods.
However,
historian
Paul
Stoker
thinks
this
can’t
be
true
because
Stonehenge
was
built
so
many
centuries
ago.
“The
leaders
arrived
in
England
much
later”,
he
points
out.

Another

idea
is
that
Stonehenge
might
be
a

of
calendar.
The
large
stones
were
put
together
in
a
certain
way.
On
midsummer’s
morning,
the
sun
shines
directly

the

of
the

Other
people
believe
the
stones
have
a
medical

They
think
the
stones
can
prevent

and
keep
people
healthy.
“As
you
walk
there,
you
can
feel
the
energy
from

your
body,”
said
one
visitor.
新课讲解
No
one
is
sure
what
Stonehenge
was
used
for,
but
most
agree
that
the
position
of
the
stones
must
be
for
a
special
purpose.
Some
think
it
might
be
a
burial
place
or
a
place
to

Others
think
it
was
built
to
celebrate
a

Stonehenge
was

a
long
period
of
time.
Most
historians
believe
it
must
be
almost
5,000

One
of
the

新课讲解
In

a

tried
to

another
Stonehenge,
but
they
couldn’t.
“
We
don’t

says
Paul
Stoker.
“And
