爱华网语态(Voice)，作为一个语法范畴，是表示主语和动词之间的主动或被动关系的动词行式。英语动词有两种语态：主动语态(Active Voice)和被动语态(Passive Voice)。当主语为动作执行者即施动者时，动词用主动态；如果主语是动作的承受者即受动者时，动词便用被动态。例如：
(1) John helped Peter.
(2) Peter was helped by John.
句(1) helped是主动态；句(2)was helped是被动态,可见主动态是无标记的，而被动态是有标记的。
构成
被动语态由助动词be的时态之一和及物动词的过去分词构成。被动语态可用于各种时态，其时态变化通过助动词be的不同形式来体现。如：一般现在时的被动态构成形式为助动词am/is/are + 过去分词；而一般过去时的被动态构成形式为was/were + 过去分词。本册要掌握的被动语态形式有：
一般现在时：am/is/are + 过去分词
e.g. Football is played all over the world.
I’m often asked to do this work.
我常常被派做这项工作。
一般过去时：was/were +过去分词
e.g. The terracotta warriors were found in 1974 near Xi’an.
They were discovered by workers in a field outside the city.
When was the building completed?
这座大楼什么时候建成的？
一般将来时：will (shall) + be +过去分词
be going to + be + 过去分词
e.g. The result of the exam will be known soon.
They are going to be given a difficult test.
一般过去将来时：should(would) be+过去分词
e.g. The teacher said the results would be published soon.
He told me that the film would be shown the next week.
现在进行时：am/is/are + being +过去分词
e.g. The new airport is being built by a foreign company.
一家外国公司正在承建这座新机场。
The song is being sung by the girls now.
过去进行时：was/were being+过去分词
e.g. The song was being sung by the girls when I got there.
The student was being criticized when I went into the
teacher’s office.
将来完成时：will have been+过去分词
e.g. By the end of next term 2000 English words will
have been learned.
The building will have been built by next year.
现在完成时：has/have + bee n +过去分词
e.g. All the tickets have been sold .
The book has been translated into many languages.
这本书已被译成多种语言。
过去完成时：had been+过去分词
e.g. Forty schools had been visited by last year.
All the tickets had been sold out when I got to the cinema.
过去将来完成时：would have been+过去分词
e.g. He said many words would have been learned by 2001.
They promised that ten books would have been published
by the next month.
情态动词：情态动词 + be + 过去分词
e.g. This road must be mended.
The machine parts may be needed in our work.
工作中可能需要这些机器零部件。
动词不定式：to be + 过去分词
e.g. I’m glad to be asked questions.
It is impossible for lost time to be made up.
失去的时间不可弥补。
主要用法
被动态常用于下列几种场合：
1．当不知道或不必提出动作的执行者时（这时都不带由by引起的短语）；
Printing was introduced into Europe from China.
印刷术是从中国引入欧洲的。
The airplane was made in U.S.
Such books are written for children. 这种书是为儿童写的。
2. 动作的承受者是谈话的中心（这时可带有由by引起的短语）；
The song was composed by a student.
这首歌曲是一个学生谱写的。
Thousands of rivers are polluted in the country.
3. 出于礼貌措词等原因而不愿说出动作执行者是谁。
You are requested to get here in time.
请您准时来这儿。
带行为主体的被动态
行为主体就是动作的执行者，即执行动词所表达的动作的人或物。在被动句中，往往不提及行为主体；但当强调动作的执行者时，可用介词by引出行为( by +主体行为主体),置于被动态句的末尾，说明是什么人或物应对有关事件负责。

被动语态四

四、被动语态与系表结构
所谓系表结构，在此指“连系动词+用作表语的动词-ed形式”结构。它与被动语态的形式完全一样，所以在应用时应注意它们的区别。
A. 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+人或by+抽象名词表动作的执行者，而后者则一般不用。
The gate to the garden was locked by the girl. 花园门被那个女孩锁上了。（被动结构）
The gate to the garden was locked. 花园门锁了。（系表结构）
The tree was blown down by the high winds. 那棵树被大风吹倒了。（被动结构）
The tree was blown down when we saw it. 我们看到那棵树时，它已经被吹倒了。（系表结构）
注意：
少数“连系动词be + 用作表语的动词-ed形式”也带by短语。
The old man was surrounded by small children. 老人被孩子们团团围住。（被动语态）
<?xml:namespace prefix = st1 ns = "urn:schemas-microsoft-com:office:smarttags" />Guilin is surrounded by hills and mountains. 桂林周围都是山。（系表结构）
We were held up by fog. 我们因雾受阻。（被动语态）
The tree is known by its fruit. 看到果子就知道是什么树。（系表结构）
B. 系表结构一般只用于一般现在时、一般过去时等少数几种时态；而被动语态可用多种时态。
The composition is well written. 这篇作文写得很好。（系表结构）
The composition is being written. 这篇作文正在写。（被动语态）
C. 系表结构中的过去分词可被very, too, so修饰，被动语态中的过去分词须用much修饰。
The boy was too frightened to move. 这孩子吓得动也不敢动。（系表结构）
He was very excited.他很激动。（系表结构）
He was much excited by the news. 他听到消息后很激动。（被动结构）
D. be + 不及物动词的过去分词通常是系表结构。
Her money is all gone. 她的钱都花光了。
The honoured guests are arrived. 贵宾们到了。
The moon is risen. 月亮升起来了。
She is grown up. 她长大了。
The leaves are fallen. 树叶落了。
We are prepared for the worst. 我们已准备好应付最坏的情况。
E. 表示“充满”意思的“be + 过去分词 + with”结构多为系表结构。
The mountain is covered with snow all the year round. 这座山终年被积雪覆盖。
The classroom was crowded with pupils. 教室里挤满了学生。
The lake is dotted with fishing boats. 湖里渔帆点点。
The floor was piled with old books. 地板上堆满了旧书。
F. remain, feel, lie, stand 以及 become, grow 等词 + 过去分词结构多为系表结构。
The matter remained unsettled. 这件事悬而未决。
She felt disappointed. 她感到失望。
The road became crowded. 道路拥挤了。
G. 句中有时间状语和地点状语时，一般为被动语态，反之为系表结构。
The bank is closed. 银行现在关门了。（系表结构）
The bank is usually closed at six. 银行通常六点关门。（被动语态）
He is married. 他结婚了。（系表结构）
He was married in Beijing. 他是在北京结婚的。（被动语态
