1.Do
you
think
we
may
be
allowed
to
take
photos
if
we
don’t
use
a
flash 你认为如果我们不使用闪光灯，我们可能被允许拍照吗？
【句型解析】此句是一个含有if
引导的条件状语从句的复合句。if
引导状语从句既可放于主句之前，也可以放在主句之后，当从句在主句前时，用逗号将其与主句隔开。
if引导的条件状语从句的时态一般遵循以下原则：如果主句的谓语含有情态动词can,
may
,
must等，或主句是祈使句时，从句用一般现在时代替将来时；如果主句是一般将来时，从句也用一般现在时代替将来时。

2.I'll
bring
my
camera
anyway.
反正我会把我的相机带来。
【词汇解读】
anyway为副词，在此意为“无论如何；反正”，在句中充当状语，用于转换话题、结束谈话或回到原话题上，相当于anyhow.
anyway还可表示“至少”，用于纠正说过的话。
【活学活用】1)
尽管他远不及完美，但她还是爱他。
2）他在这儿工作。至少我上次见他时是。
3)好了，我得走了，已经迟到了。
He's

定义
含情态动词的被动语态用来说明某个被动性动作所反映出的感情和态度。初中阶段的常见情态动词有：can,
may
,
need
,
must
,
should等。
谓语部分含有情态动词的被动语态的构成是：情态动词+be+过去分词。
例句：
Teenagers
should
be
allowed
to
choose
their
own
clothes.
应该允许青少年选择他们自己的服装。
Students
should
not
be
allowed
to
have
part-time
jobs.
不应该允许学生们做兼职工作。
Can
these
books
be
taken
out
of
the
reading
room
可以把这些书带出阅览室吗？
When
must
the
work
be
finished
这些工作必须什么时候完成？
转变方法
(一)将主动语态的宾语变成被动语态的主语。
(二)将含情态动词的主动句式变成被动句式，即：
“情态动词+动词原形”变成“情态动词+be+过去分词”，然后再在其后加“by+主动句中的主语(人称代词用宾格)”。by短语也可省略。请看下列各句：
You
should
finish
your
homework
first.
Your
homework
should
be
finished
(by
you)
first.
You
can
take
this
magazine
home.
This
magazine
can
be
taken
home
(by
you).
句式变换
含情态动词的疑问句、否定句的变化均需借助于情态动词完成。
1.
一般疑问句：直接将被动语态的陈述句中的情态动词提前。
Must
this
task
be
finished
at
once 这项任务必须立即完成吗？
注意：含情态动词的被动语态的一般疑问句的回答，应保留原情态动词，但must表“必须”时，其否定回答应用needn’t；need表“必要”时，其肯定回答应用must。如：
---
Must
my
exercise
book
be
handed
in
now
我的练习本必须现在上交吗？
---
Yes,
it
must.
是的，必须现在上交。
（No,
it
needn’t.
不，不必现在上交。）
2.
特殊疑问句
：由特殊疑问词加上被动语态的一般疑问句构成。
When
must
this
task
be
finished
这项任务必须在什么时候完成？
3.
否定句：
在情态动词后面加上not或never即可，但must表"必要"时否定式为needn't。
This
task
needn't
be
finished
at
once.
这项任务没必要立即完成。
4.
反意疑问句：借助情态动词构成附加疑问部分。如：
This
bridge
can
be
built
next
year,
can't
it
这座桥明年能建成，是吗？

Tree

only.
A.
should
plant
B.
should
be
planted
C.
should
be
plant
D.
should
be
planting
考查情态动词的被动语态。句意：一些人认为只应该在植树节那天种树。think引导的宾语从句的主语trees，和动词plant之间是被动的关系。应用被动语态，即should
+
be
+动词的过去分词。故选B。
2.(2019四川自贡)28.
—Tom

careless
with
his
schoolwork.

him？
—No

I
think
he
___________to
think
twice
before
starting.
A.
should
be
told
B.
shouldn't
be
told
C.
should
tell
考查被动语态。句意：——汤姆对他的学业总是很粗心。你能帮助他吗？——没问题。我想应当告诉他在开始之前思考两遍。空白处主语he与选项谓语动词tell之间是动宾关系，用被动语态；根据语境可知应当是“应当告诉他”，故选A。
3.
(2019营口)Don't

until
you
come
back,
please
enjoy
shopping
here.
A.
will
keep
B.
keep
C.
can
be
kept
D.
kept
【解析】C。本题考查含有情态动词can的被动语态结构。句意
“不要担心。你的包可以一直放在这儿
直到你回来，你就这购物吧”
。包package和keep保存是被动关系，排除法只能选C。注意，选项A改为will
be
kept将被保存，也符合句意。

考点精析】句意：—期末考试就要来了，汤姆。不要看太长时间的电视。—我不再是个孩子了。我不应该总是被告知该做什么。考查被动语态。主语是I动词tell的承受者，所以使用被动语态形式，因此B/D不对。由句子I’m
not
a
child
any
more.
我不再是个孩子了。可知，下句应该用被动句的否定形式。故选C。
