2018考研英語:長難句練習(xí)及解析(40)

字號:

It’s a theory to which many economists subscribe, but in practice it often leaves railroads in the position of determining which companies will flourish and which will fail.
    【核心詞匯】
    subscribe v.訂閱,同意
    flourish v.繁榮,興旺
    determine v.決定,判決,使……下定決心
    in practice實(shí)際上
    【結(jié)構(gòu)分析】
    本句是由but連接兩個分句,第一個分句的主干部分是It’s a theory,后面緊跟了一個which引導(dǎo)的定語從句,but后面的分句主語是it,謂語是leaves,determining是介詞of的賓語,后邊接了兩個并列的賓語從句:which companies will flourish and which will fail。
    【參考譯文】
    這種理論得到了多數(shù)經(jīng)濟(jì)學(xué)家的認(rèn)同,但在實(shí)際操作中,它常常使得鐵路公司處于決定誰興誰敗的位置。
