托福考試改錯題常考要點及例題分析(上)Ⅲ

字號:

三、謂語動詞
    (一) 謂語動詞的主謂一致來源:考試大 ?、?、主謂分割原則
    例1:To the citizens of the United States, the bald eagle,
      A    
      America's national bird, symbolize strength and freedom.
         B      C      D
    分析:C錯,應改為symbolizes。主語謂語用逗號分割開,主語the bald eagle為單數(shù),謂語動詞也應該用單數(shù)形式。
    ②、與后者一致原則
    not…but, 強調but后面的名詞,來源:考試大  not only…but also來源:考試大  ③、與前者一致原則來源:考試大  名詞+with/together with/as well as/including+復數(shù)名詞,謂語用is,
    中心詞在前面,謂語動詞應該與前面的名詞保持一致
    例:The athlete, together with his coach and
      A      B  C    
     several relatives, are traveling to the Olympic Games.
          D
    分析:D錯,與謂語動詞與the athlete 保持一致,改為is
    ④、就近原則來源:考試大  or, either…or, neither…nor,
    單數(shù)名詞+or+復數(shù)名詞+are
    如果把句子變?yōu)橐话阋蓡柧洌簿褪前裝e動詞提到前面,那么變?yōu)閕s
    所以注意一點: 如果是陳述句,靠后面近,用復數(shù)
         如果是疑問句,靠前面近,用單數(shù)
    例:The structure or behavior of many protozoans are
         A      B       
     amazingly complex for single-celled animals.
     C              D
    分析:A錯,應改為and。從謂語動詞是復數(shù)形式判斷,主語應該為復數(shù),or連接兩個名詞時動詞和后面的名詞保持一致,behavior是用單數(shù)形式,因此只有改為并列連詞and才能使主謂在數(shù)上保持一致。
    ⑤定語從句主語就近原則來源:考試大  There are five apples that are red.
    apples是復數(shù),因此從句謂語動詞是復數(shù)。
    例:A rocket burns propellant rapidly and most rockets
       A           
     carry a supply that last just a few seconds.
    B   C    D
    分析:D錯,應改為lasts。從句的邏輯主語a supply為單數(shù),其謂語動詞應為單數(shù)形式。
    ⑥the +形容詞主謂一致來源:考試大  The rich are not always happier than the poor.
    The rich 表示一類人,應該用復數(shù)
    ⑦、倒裝句的主謂一致
    改錯題倒裝句的主謂一致一般考兩種情況:來源:考試大  a. there be 句型
    there be+名詞+名詞,那么最近的名詞決定其形式
    b. between/ among 放在句首+be+名詞,名詞其實是主語,所以be和名詞保持一致
    例:There are no known society in which left-handed people predominate.
    A     B      C    D   
    分析:there be 句型由最近的名詞決定其形式,society當然用單數(shù),A錯,there are 改為there is
    例:Between the foothills of the Andes and the Pacific
              A     B   
     Ocean are a dry coastal strip averaging about 30
      C        
     miles in width.
      D 
    分析:倒裝句,are改為is來源:考試大  
    例:Among the favorite attractions at the National Air and
      A    B    C        
     Space Museum in Washington D.C. are the film
                     D
     presented on the five-story-tall screen.
    分析:D錯,應改為films , 主語實際上是名詞,應該與謂語動詞保持一致。
    ⑧、百分比結構的主謂一致
    fifty percent of + 名詞
    one percent of + 名詞來源:考試大  謂語動詞的形式和百分比多少沒有關系,主要取決于后面的名詞,比如:
     one percent of my students + are
     fifty percent of my time is spent on working.
    這里要強調兩個結構來源:考試大  half of =fifty percent
    most of + 可數(shù)名詞 + are
    most of + 不可數(shù)名詞+ is來源:考試大  
    例:Nearly half of the ancient meteor craters has been
    A       B        C  
     found in central and eastern Canada.
            D
    分析:C錯,應改為have been。介詞of的賓語為復數(shù)名詞短語,作主語的中心詞half當然表復數(shù),相應的謂語動詞應為復數(shù)形式。
    例:Approximately fifty percent of the package utilized
                  A   B 
     in the United States are for foods and beverages.
               C     D
    分析:A錯,應改為packages。從謂語動詞用復數(shù)形式判斷出主語是復數(shù)名詞。注意food用復數(shù)表示不同種類的食品,beverage用復數(shù)表示不同種類的飲料,故(C)、(D)均沒有錯。
    (二) 謂語動詞的時態(tài)來源:考試大 ?、?、主要考察時間狀語
    例 The metal aluminum has been first isolated early in the nineteenth century.
    A        B  C     D
    分析:Metal, aluminum同位語,in the nineteenth century為明顯表示過去時間的狀語, 因此應該用過去時態(tài),把has been改為was
    ②、For和since的區(qū)別
    區(qū)別一:For 后面使用時間段,since 后面使用時間點
    區(qū)別二:Since 只能用在現(xiàn)在完成時態(tài),F(xiàn)or 最主要用在現(xiàn)在完成時和一般過去時
    I has been a teacher for three years.
    I has been a teacher since 1996.來源:考試大  I was a teacher for three years. 這種表達可以,for three years表示一段時間,was 表示過去做了三年,現(xiàn)在不是老師了
    例: Since 1921 the budget of the United States became
    A      B             
     the primary responsibility of the president.
      C    D
    分析:A錯,應改 In. since一般要求主句用完成時態(tài),而句中謂語動詞為過去式,其時間狀語應與之呼應,故改Since為In。
    例:Adella Prentiss Hrghes served as manager of
              A  B  C  
     the Cleveland Orchestra since fifteen years.
             D
    分析:D錯,應改為for。since引導時間狀語時,主句謂語動詞為一般完成時;主句謂語動詞為一般過去時要用介詞for;而且一段時間用for, 而不是since。
    52. In general, prawns lived in shallow coastal waters or in streams. 
    A       B        C     D
    自然現(xiàn)象和客觀事實用一般現(xiàn)在時態(tài),live
    (三) 謂語的語態(tài)來源:考試大  語態(tài)主要表示是主動語態(tài)還是被動語態(tài)。 來源:考試大  有四組動詞是改錯題中常考的:來源:考試大 ?、佟rove
    My advice proved to be wrong. 我的建議被證明是錯的
    盡管是被證明,但習慣上用主動;
    例:A majority of the reports received from people claiming
                       A  
     to have seen the legendary Loch Ness Monster have proven to be
     B                  C
     mistakes, misconceptions, or they were being tricked.
                 D
    分析:D錯,應改為tricks。并列連詞 or在此連接名詞,如果把D理解為并列句,不僅時態(tài)不對,語義也有問題,故將整個句子改為名詞。have proven to be是正確的。
    ②、Locate,Situate
    這兩個詞可以用作主動,表示把…放置在…地方;確定…的位置
    Bats locate obstacles.蝙蝠確定障礙物的位置
    這兩個詞也可以用作被動來源:考試大  My school was located near the river.
    區(qū)分locate的主動和被動比較難,但是有一個技巧存在:locate如果用作主動,后面必須跟賓語
    例:The center of gravity of the human body ---- behind the hip joint.
    (A)locates來源:考試大
    (B)locating
    (C)to locate
    (D)is located 來源:考試大  分析:空格處顯然缺謂語動詞,故首先排除不能作謂語的B和C。動詞locate后面沒有賓語,所以用作被動,表示“位于”,所以D為正確選項。
    ③、表示需要概念的動詞
    need, want, require等
    My watch needed repairing
    My watch needed to be repaired.
    ④、表示人的情感的動詞
    move, annoy, surprise, please等
    He is so moving.  他令人感到感動。來源:考試大  He is greatly moved. 他感到非常感動。
    主動和被動技巧總結:
    如果句子中有一個“過去分詞+by”, 如果斷定它是謂語的話,前面必然有be動詞
    例:The Tennessee Valley Authority has chartered by the
                  A     
     United States Congress in 1933 to construct dams,
                  B
     power structures, and flood-control works along
                     C
     the Tennessee River and its tributary streams.
                 D
    分析:A錯,應改為has been chartered。由信號詞by可知前面的謂語動詞為被動語態(tài)形式。
