英語(yǔ)動(dòng)詞分謂語(yǔ)動(dòng)詞（含系動(dòng)詞）和非謂語(yǔ)動(dòng)詞（分詞、不定式及動(dòng)名詞）兩類。動(dòng)詞既以謂語(yǔ)的功能出現(xiàn)，它就具有了形式上的多種變化；時(shí)態(tài)、語(yǔ)態(tài)及主謂數(shù)的統(tǒng)一等等。有關(guān)謂語(yǔ)動(dòng)詞的命題焦點(diǎn)主要集中在（1）區(qū)分謂語(yǔ)動(dòng)詞非謂語(yǔ)動(dòng)詞（詳見(jiàn)本書(shū)要點(diǎn)之1）、（2）謂語(yǔ)動(dòng)詞的正確詞形，（3）被動(dòng)語(yǔ)態(tài)的正確詞形、（4）謂語(yǔ)動(dòng)詞的正確時(shí)態(tài)、（5）謂語(yǔ)動(dòng)詞與主語(yǔ)數(shù)的一致。
謂語(yǔ)動(dòng)詞�？碱}型及解題要點(diǎn)
1.區(qū)分謂語(yǔ)動(dòng)詞及非謂語(yǔ)動(dòng)詞形式
[例1] The“ ashcan” school in American art being a rebellion against traditional subjects and favored the painting of back-street scenes.

例題分析

(2) The tradition of an all-male Supreme Court was broke in the 1980*s when Sandra Day O*Connor was appointed to the Supreme Court.
[答案] break 的過(guò)去分詞是broken。
(3) A citadel, a fortress designed for the defense of a city, usually standed on top of a hill.
[答案] standed是錯(cuò)誤形式，應(yīng)改為stood。
3. 謂語(yǔ)動(dòng)詞的被動(dòng)語(yǔ)態(tài)
解題要點(diǎn) 動(dòng)詞的被動(dòng)語(yǔ)態(tài)是常見(jiàn)的題型。它通常需要根據(jù)句意來(lái)判斷。介詞by是一個(gè)明顯的提示。
例題分析
(1) People have always fascinated by the parrot*s colovfal feathers and its ability to mimic human speck
[答案] 關(guān)鍵詞by表示動(dòng)詞應(yīng)用被動(dòng)形式，即always been fascinated。
(2) Porgy and Bess by George Gershwin has called the first truly successful North American opera.(93.10)
[答案] 根據(jù)句意，此句應(yīng)用被動(dòng)語(yǔ)態(tài)，即has been called.
(3) Tariffs are the taxes or customs duties levied against goods that are import from another country (93.10)
[答案] 正確的被動(dòng)語(yǔ)態(tài)應(yīng)用過(guò)去分詞，即imported。
(4) Almost destroy by fire in 1814. The White House was rebuilt and enlarged over the next three years.
[答案] 關(guān)鍵詞by表明前面的動(dòng)詞應(yīng)用被動(dòng)的形式，即Almost destroyed。
(5) The unit of measurement known as a *foot* has originally based on the average size of the human foot
[答案] 根據(jù)句意，謂語(yǔ)動(dòng)詞應(yīng)用被動(dòng)的形式，因而has 應(yīng)改為was，而且“be based on’是固定的動(dòng)詞短語(yǔ)。
4. 根據(jù)特定的時(shí)間狀語(yǔ)使用正確的動(dòng)詞時(shí)態(tài)
解題要點(diǎn) 一般過(guò)去時(shí)和完成式是常考的兩個(gè)有關(guān)動(dòng)詞時(shí)態(tài)的命題。請(qǐng)?zhí)貏e注意相關(guān)的時(shí)間狀語(yǔ)。如阿拉伯?dāng)?shù)字表示的年代，介詞since和for＋一段時(shí)間等等。
例題分析
(1) Considered one of America*s greatest playwrights, Eugene O*Neill win the Nobel Prize of literature in 1936.
[答案] 時(shí)間狀語(yǔ)in 1936表明謂語(yǔ)動(dòng)詞應(yīng)用一般過(guò)去時(shí)won。
(2) Since the turn of the century,the number of Native Americans living in Canada is increased.
[答案] 句首介詞sina 要求用完成式，故is increased 改為has increased。
(3) The metal aluminum has been first isolated early in the nineteenth century.
[答案] 時(shí)間狀語(yǔ)in the nineteenth century要求謂語(yǔ)動(dòng)詞用一般過(guò)去時(shí)was。
(4) For centuries large communities of people have living on houseboats in parts of the world where the climate is warm and the waters are calm.
[答案] 句首介詞短詞For centuries 表明此句應(yīng)用完成式，而have living是錯(cuò)誤的形式，應(yīng)改為have been living。
5. 復(fù)合句或并列句中的謂語(yǔ)動(dòng)詞時(shí)態(tài)應(yīng)前后統(tǒng)一
例題分析
(1) Before the plains were settled prairie dog towns in many places stretch as far as the eye could see. (93.5)
[答案] 這是個(gè)含有時(shí)間狀語(yǔ)從句的復(fù)合句。從句是一般過(guò)去時(shí)(were settled)主句亦應(yīng)用一般過(guò)去時(shí)。故stretch應(yīng)改為stretched。
(2) The poet Marianne was initially associated with the imagist movement. But later develops her own rhyme patterns and verse forms.
[答案] 并列句（由but相聯(lián)）前后兩個(gè)句子的時(shí)態(tài)一般要求一致。Develops 應(yīng)改為一般過(guò)去時(shí)developed。
(3) Coal and petroleum resulted when plants become buried in swamps and decayed.
[答案] 主句是一般過(guò)去時(shí)(resulted)，時(shí)間狀語(yǔ)從句亦應(yīng)用相同的時(shí)態(tài)，即became
6. 謂語(yǔ)動(dòng)詞應(yīng)與主語(yǔ)的單復(fù)數(shù)保持一致
解題要點(diǎn)這類試題的難點(diǎn)是當(dāng)主語(yǔ)謂語(yǔ)相隔遙遠(yuǎn)時(shí)，如主語(yǔ)帶一冗長(zhǎng)的定語(yǔ)后置謂語(yǔ)動(dòng)詞的數(shù)常會(huì)出現(xiàn)錯(cuò)誤的形式，
例題分析
(1) Contemporary management practice have been influenced by investigations in the behavioral sciences. (93.10)
[答案] 主語(yǔ)是單數(shù)的practice，謂語(yǔ)動(dòng)詞應(yīng)改為has been。
(2) Even in an age of experimentation and departures from convention, the sonata form remain among the most vital means of musical expression.
[答案] 單數(shù)主語(yǔ)sonata form要求用單數(shù)第三人稱謂語(yǔ)動(dòng)詞remains。
(3) The ability to retain a mental record of earlier experiences are referred to as “memory”.
[答案] 由于主語(yǔ)The ability 后面帶有一冗長(zhǎng)的定語(yǔ)，謂語(yǔ)錯(cuò)誤地使用了復(fù)數(shù)形式，應(yīng)改為is referred。這類題型是有關(guān)主謂數(shù)的命題中最難的形式，當(dāng)主語(yǔ)后面接有一個(gè)很長(zhǎng)的定語(yǔ)而使主謂分隔開(kāi)來(lái)時(shí)，應(yīng)特別留意謂語(yǔ)動(dòng)詞的數(shù)是否與主語(yǔ)一致。這類題的陷井是定語(yǔ)部分靠近謂語(yǔ)的那個(gè)名詞的數(shù)恰恰與主語(yǔ)的數(shù)相反，極易誤導(dǎo)謂語(yǔ)動(dòng)詞的數(shù)的形式。
(4) Its tremendous output of dairy products have earned the state of Wisconsin the title of America*s Dairyland.
[答案] 主語(yǔ)是單數(shù)形式的output，故謂語(yǔ)動(dòng)詞應(yīng)改為has。介詞短語(yǔ)of dairy products 作主語(yǔ)的定語(yǔ)。
(5) Ensuring an adequate water supply have been a concern ever since people began to live in towns and cities .
[答案] 主語(yǔ)是動(dòng)名詞短語(yǔ)Ensuring an adequate water supply動(dòng)名詞作主語(yǔ)要求單數(shù)謂語(yǔ)動(dòng)詞。
