    典型例題

    1）the weather in china is different from____.
    a. in america　 b. one in america　 c. america   d. that in america

    答案：d。本題意為“中國(guó)的天氣與美國(guó)的不同。”比較的是天氣而不是國(guó)家，c不能選。a沒(méi)有名詞，后句成分不全，排除。b和d中，b中的one常用來(lái)代替可數(shù)名詞，而that可以代替不可數(shù)或抽象名詞，所以選d。

    2）after the new technique was introduced, the factory produced ___ tractors in 1988 as the year before.
    a. as twice many　　b. as many twice　　c. twice as many　d. twice many as

    答案c。此句意為“引進(jìn)新技術(shù)以后，這個(gè)廠(chǎng)1988年生產(chǎn)的拖拉機(jī)是往年的兩倍”。表示倍數(shù)用“倍數(shù)+ as + 形容詞原形+ as +比較對(duì)象”的句型。所以此句答案為c。

    this ruler is three times as long as that one.
