語(yǔ)態(tài)(Voice)，作為一個(gè)語(yǔ)法范疇，是表示主語(yǔ)和動(dòng)詞之間的主動(dòng)或被動(dòng)關(guān)系的動(dòng)詞行式。英語(yǔ)動(dòng)詞有兩種語(yǔ)態(tài)：主動(dòng)語(yǔ)態(tài)(Active Voice)和被動(dòng)語(yǔ)態(tài)(Passive Voice)。當(dāng)主語(yǔ)為動(dòng)作執(zhí)行者即施動(dòng)者時(shí)，動(dòng)詞用主動(dòng)態(tài)；如果主語(yǔ)是動(dòng)作的承受者即受動(dòng)者時(shí)，動(dòng)詞便用被動(dòng)態(tài)。例如：
(1) John helped Peter.
(2) Peter was helped by John.
句(1) helped是主動(dòng)態(tài)；句(2)was helped是被動(dòng)態(tài),可見(jiàn)主動(dòng)態(tài)是無(wú)標(biāo)記的，而被動(dòng)態(tài)是有標(biāo)記的。
構(gòu)成
被動(dòng)語(yǔ)態(tài)由助動(dòng)詞be的時(shí)態(tài)之一和及物動(dòng)詞的過(guò)去分詞構(gòu)成。被動(dòng)語(yǔ)態(tài)可用于各種時(shí)態(tài)，其時(shí)態(tài)變化通過(guò)助動(dòng)詞be的不同形式來(lái)體現(xiàn)。如：一般現(xiàn)在時(shí)的被動(dòng)態(tài)構(gòu)成形式為助動(dòng)詞am/is/are + 過(guò)去分詞；而一般過(guò)去時(shí)的被動(dòng)態(tài)構(gòu)成形式為was/were + 過(guò)去分詞。本冊(cè)要掌握的被動(dòng)語(yǔ)態(tài)形式有：
一般現(xiàn)在時(shí)：am/is/are + 過(guò)去分詞
e.g. Football is played all over the world.
I’m often asked to do this work.
我常常被派做這項(xiàng)工作。

這座大樓什么時(shí)候建成的？
一般將來(lái)時(shí)：will (shall) + be +過(guò)去分詞
be going to + be + 過(guò)去分詞
e.g. The result of the exam will be known soon.
They are going to be given a difficult test.
一般過(guò)去將來(lái)時(shí)：should(would) be+過(guò)去分詞
e.g. The teacher said the results would be published soon.
He told me that the film would be shown the next week.
現(xiàn)在進(jìn)行時(shí)：am/is/are + being +過(guò)去分詞

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.
將來(lái)完成時(shí)：will have been+過(guò)去分詞
e.g. By the end of next term 2000 English words will
have been learned.
The building will have been built by next year.
現(xiàn)在完成時(shí)：has/have + bee n +過(guò)去分詞
e.g. All the tickets have been sold .

主要用法
被動(dòng)態(tài)常用于下列幾種場(chǎng)合：
1．當(dāng)不知道或不必提出動(dòng)作的執(zhí)行者時(shí)（這時(shí)都不帶由by引起的短語(yǔ)）；
Printing was introduced into Europe from China.
印刷術(shù)是從中國(guó)引入歐洲的。
The airplane was made in U.S.
Such books are written for children. 這種書是為兒童寫的。
2. 動(dòng)作的承受者是談話的中心（這時(shí)可帶有由by引起的短語(yǔ)）；
The song was composed by a student.
這首歌曲是一個(gè)學(xué)生譜寫的。
Thousands of rivers are polluted in the country.
3. 出于禮貌措詞等原因而不愿說(shuō)出動(dòng)作執(zhí)行者是誰(shuí)。
You are requested to get here in time.
請(qǐng)您準(zhǔn)時(shí)來(lái)這兒。
帶行為主體的被動(dòng)態(tài)
行為主體就是動(dòng)作的執(zhí)行者，即執(zhí)行動(dòng)詞所表達(dá)的動(dòng)作的人或物。在被動(dòng)句中，往往不提及行為主體；但當(dāng)強(qiáng)調(diào)動(dòng)作的執(zhí)行者時(shí)，可用介詞by引出行為( by +主體行為主體),置于被動(dòng)態(tài)句的末尾，說(shuō)明是什么人或物應(yīng)對(duì)有關(guān)事件負(fù)責(zé)。
e.g. The village was destroyed by a bomb.
這個(gè)村莊毀于炸彈。
