语法精析
本单元和六单元非常类似，讲的都是被动语态，但是该单元主要学到的是含有情态动词的被动语态的用法
理解含情态动词的被动语态的概念含情态动词的被动语态说明某个被动性动作所反映出的感情和态度。
初中阶段学习的可用于被动语态的情态动词有can,may,must,need,
should等,分别表示“能够被……”,“可以被……”,“必须被……”,“需要被……”,“应该被…“等
二、掌握含情态动词的被动语态的不同句式的变换方法含情态动词的被动语态的疑问句、否定句的变化均借助于情态动词来完成
(一)一般疑问句是直接将陈述句被动语态中的情态动词提前。如:
Must
this
work
be
done
at
once?
这项工作必须立即完成吗?
(二)特殊疑问句由疑问词加上一般疑问句的被动语态构成。如:
When
must
this
work
be
done?
这工作必须在什么时候完成?
(三)反义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?
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
(四)否定句是在情态动词后面加上not或即可,但must表“必要”时,否定式为
needn't。如:
This
dustbin
shouldn't
be
put
here.
这个垃圾箱不应放在这儿
三、含情态动词的被动语态的一般疑问句的回答如:
—Should
my
exercises
be
finished
today?
—我的作业应在今天完成吗?
—Yes,
they
should..是的,应在今天完成
(No,
they
shouldn't.不,不应在今天完成。)
—Need
he
be
operated
on
at
once??他必须立即手术吗?
—Yes,
he
must..是的,他必须
(No,
he
needn't.不,他不必。)
