must一定，必须；C.
need需要；D.
might或许。本题主要考查情态动词表示推测的用法，由I’m
going
back
to
check
anyway可知，我对此不确定。由此可知，D项符合题意。故选D项。
【点睛】can
/
could用于表推测的用法
(1)?从使用句型上看，can?通常只用于否定句或疑问句，一般不用于肯定句，而could?可用于肯定句、否定句和疑问句。两者没有时间上的差别，只是could?比
can?更委婉，更不确定。
(2)?从时间关系看，对现在或将来情况作推测，后接动词原形；对正在进行的情况作推测，后接?be
doing?结构；对过去情况作推测，后接动词完成式。
二、?may
/
might用于表推测的用法
表示推测，两者都可用，只是?might?比?may?语气更不确定，表示的可能性更小。如本题，根据I’m
going
back
to
check
anyway可知，我对此不确定。由此可知，D项符合题意。(1)?在句型使用方面：两者均可用于肯定句和否定句，但用于疑问句时，may通常不用于句首，但可用于疑问句的句中（如特殊疑问句等），而might尽管可以用于疑问句的句首，但不算普通，通常会改用其他句式（如用could等）。
三、must表示推测的用法
must?表示很有把握的推测，其意为“一定会”“肯定会”，只用于肯定句，一般不用于否定句或疑问句。表示对现在或未来的情况作推测，后接动词原形；表示对过去情况的推测，接动词完成式。

got
to不得不，表示客观上必须做的；???
B.

able
to有能力做某事；

glad
to很高兴；D.

D
【详解】考查情态动词用法。句意：如果我们对超载车辆问题给予足够的重视，就可以避免无锡立交桥垮塌的悲剧。本句为“情态动词+have
done”结构，结合句意表示“本来可以；本来能够”应用could
have
done结构，且主语与谓语动词avoid构成被动关系，故应用be
done形式。故选D。
【点睛】情态动词+have
done的结构和用法有以下几种：
一、must
have
done
sth.“一定做了某事”。表示对过去事情的较有把握的推测，这时只能用在肯定句中，“肯定/必须已经干过……”，在否定句和疑问句中用can’t或couldn’t或can/
could，例如：
1.From
what
you
said,
she
must
have
told
you
all
about
it.
从你的话看，她一定告诉了你所有的事情。
二、can/could
have
done
sth.本来能够做某事，而实际上未做；
1.But
we
could
have
done
it
all
so
much
better.
但是，我们本可以把这一切做得更好。
三、can't/couldn't
have
done
sth.不可能做过某事；
1.
We
could't
have
done
it
without
you.
没有你我们办不成这事。
四、ought
to/should
have
done
sth.过去本应该做某事而实际上并没有做。
You
should
have
done
it
when
you
first

a
place?

can?????????????
B.
must?????????????
C.

D.
might
【答案解析】
D
【详解】考查情态动词辨析。句意：今天的交通很拥挤。我也许晚一点到，你能给我留个地方吗？此处指“我也许会晚到一会”。表示事实上的可能性，用may或might，can表示逻辑的可能性；must表示肯定性推测，根据语境，可能性不大，故不用must；dare表示“敢”。综上所述，故选D。
16.
–Do
you
know
where
David
is?

【答案解析】
C
【详解】考查情态动词+have

shouldn’t
have
done本不应该做某事；B.
mustn’t
禁止；C.
can’t
have
done???
不可能做过某事；D.
wouldn’t
have
done虚拟语气，是否定性推测，表示对过去事情的假设。根据his
coat
is
still
here可知这里意思是他不可能走远了，故选C。

She
looks

the
exam.
A.
can
have
passed?????????????
B.
should
have
passed?????????????
C.
must
have
passed?????????????
D.
could
have
passed
【答案解析】
C
【详解】考查情态动词。句意；她看起来很高兴。她一定通过了考试。must
/could+
have
done表示对过去发生的事情的推测，意为“一定/可能（已经）…
”，本句中根据语境She
looks
very
happy可判断，用
must
have
passed语气较强，意为“一定是已经通过了（考试）”，故排除D项，选C。
【点睛】本题考查情态动词完成式表推测。我们知道，表示推测的情态动词常用的有must
/
may
/
might
/
could/should/
ought
to等，其中，must语气最强，只用于肯定句中，can/could常用于否定句和疑问句，may/might常用于陈述句。其后加“have
+过去分词”形式时，常常表示对过去情况的推测。例如：
（1）It
must
/
may
/
might
/
could
have
rained
last
night.
The
ground
is
wet.地湿了，昨晚肯定/可能/也许下雨了。
（2）The
door
was
locked.
He
can
(
could
)
not
/
may
(
might
)
not
have
been
at
home
.门锁着，他不可能/可能不在家。
（3）Can
/
Could
he
have
gotten
the
book？难道他找到书了吗？
注：情态动词
should
/ought
to表推测时，意为“想必会，理应……”但与“have
+过去分词”连用时，则又可构成虚拟语气意为“本应该做某事却没做”。

must?have?done?是对过去发生的动作最有把握的猜测，意思是“一定”，结合语境可知，我没有打电话给你，因此猜测一定有别人给你打了电话
。故选A项。
