    全真例題分析
    (1) Before the plains were settled prairie dog towns in many places stretch as far as the eye could see. (93.5)
    [答案] B 這是個含有時間狀語從句的復(fù)合句。從句是一般過去時(were settled)主句亦應(yīng)用一般過去時。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. (92.5)
    [答案]B 并列句(由but相聯(lián))前后兩個句子的時態(tài)一般要求一致。Develops 應(yīng)改為一般過去時developed。

    6. 謂語動詞應(yīng)與主語的單復(fù)數(shù)保持一致。
    解題要點(diǎn) 主語謂語數(shù)的統(tǒng)一是TOEEL必考題型,而且占的比例較大。這類試題的難點(diǎn)是當(dāng)主語謂語相隔遙遠(yuǎn)時,如主語帶一冗長的定語后置謂語動詞的數(shù)常會出現(xiàn)錯誤的形式,
    全真例題分析
    (1) Contemporary management practice have been influenced by investigations in the behavioral sciences. (93.10)

    (2) Even in an age of experimentation and departures from convention, the sonata form remain among the most vital means of musical expression. (93.8)
    [答案] 單數(shù)主語sonata form要求用單數(shù)第三人稱謂語動詞remains。
    (3) The ability to retain a mental record of earlier experiences are referred to as *memory*. (92.5)
    [答案] D 由于主語The ability 后面帶有一冗長的定語,謂語錯誤地使用了復(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)主語后面接有一個很長的定語而使主謂分隔開來時,應(yīng)特別留意謂語動詞的數(shù)是否與主語一致。這類題的陷井是定語部分靠近謂語的那個名詞的數(shù)恰恰與主語的數(shù)相反,極易誤導(dǎo)謂語動詞的數(shù)的形式。
    (4) Its tremendous output of dairy products have earned the state of Wisconsin the title of America*s Dairyland. (92.1)
    [答案] C 主語是單數(shù)形式的output,故謂語動詞應(yīng)改為has。介詞短語of dairy products 作主語的定語。
    (5) Ensuring an adequate water supply have been a concern ever since people began to live in towns and cities . (90.8)   
    [答案] B主語是動名詞短語Ensuring an adequate water supply動名詞作主語要求單數(shù)謂語動詞。
