to
的不定式，并在不定式的前面根据原句的语
气（即请求或命令）加上
ask
，
tell
，
order
等动词，如果祈
使句为否定式，则在不定式前加
not
。其句型为：

/
tell
/
order someone
（
not
）
to do something
．例如：
She said to us

．
He said to him
，
“
Go away
！
”
→
He ordered him to go away
．
He said
，
“
Don
’
t make so much noise
，
boys
．
”

He told the boys not to make so much noise
．
二．各种时态的被动语态
被动语态概述
被动语态的概念：它是动词的一种形式，表示主语与谓语
之间的执行或被执行关系。主动语态表示主语是谓语动作的执
行者，
例如：
They
saw
the
little
boy
crying
by
the
river
．
被
动语态表示主语是谓语动作的承受者，例如：
The little boy
was seen crying by the river
．
被动语态的构成
被动语态的形式是由
“
助动词
be
＋动词的过去分词
”
构成。
助动词
be
随着主语的人称、数、时态等的不同而变化。几种常
见时态的被动语态形式如下：
1
．一般现在时
am/is/are
＋过去分词
例如：
Rice is planted in the south of China
．
2
．一般过去时
was/were
＋过去分词
例如：
These
trees
were planted the year before last
．
3
．一般将来时
will/shall
＋
be
＋过去分词
例如：
A sports meeting will be held next week in our
school
．
4
．现在进行时
am/is/are
＋
being
＋过去分词
例如：
Your radio is being repaired now
．
5
．过去进行时
was/were
＋
being
＋过去分词
When
he
got
there
，
the
problem
was
being
discussed
．
6
．现在完成时
have/has
＋
been
＋过去分词
His work has been finished
．
Has
his
work been
finished? Yes
，
it has
．
/
No
，
it
hasn
’
t
．
7
．过去完成时
had
＋
been
＋过去分词
注意：
1
．
除了
be
之外的其它系动词如
get
，
stay
等也可以和过去
分词构成被动语态。例如：
Their questions haven
’
t got
answered
．
2
．
含有情态动词的谓语变成被动语态使用
“
情态动词＋
be
＋过去分词
”
结构。例如：
More attention should be paid to the old in this
country
．
This work can
’
t be done until Mr
．
Black comes
．
3
．含有
“
be going to
”
，
“
be to
”
等结构的谓语，其被动
语态分别用
“
be
going
to
＋
be
＋过去分词
”
和
“
be
to
＋
be
＋
过去分词
”
。例如：
The problem is going to be discussed at the next
meeting
．
All these books are to be taken to the library
．
4
．被动语态与系表结构的区别：
“
连系动词＋用作表语的
过去分词
”
构成的系表结构，
与被动语态的形式完全一样，
所以
应注意它们的区别。被动语态中的过去分词是动词，多强调动
作；系表结构中的过去分词相当于形容词，多强调状态。前者
通常可用
by
引出动作的执行者，而后者则不可以。例如：
The map was changed by someone
．（被动结构）
That custom remained unchanged for many
centuries
．（系表结构）
系表结构中的过去分词通常可被
very
修饰，被动语态中的
过去分词往往要用
much
修饰。
在结合一些练习做做就ok了

①that引导宾语从句仅仅起引导作用，本身无具体意义，通常在非正式文体中可以省略，不引导介词的宾从（except that除外）
例子：She took it for granted that you knew the matter.
②whether获if 领导的宾从
这里的if从句不可以混淆于if引导的条件状语从句,不可以翻译成如果
Do you know whether/if any decision has been arrived at?
③连接代词和连接副词引导的宾从
连接代词有who whom whose what which;连接副词有when where how why等
I will tell you why I was late.
表语从句(标志单词：be动词）
①that引导表从不可以省略
The fact is that he didn't even take the exam.
②wh-疑问词引导的表语从句
That is why he was late for an hour.
③as if,as though,because,just as,引导的表从除because外后可以接虚拟语气
It looks as if we will be late.
主语从句
先行词通常是what
I don't know what he said.
