    D) which


    正确答案：D

  • 第3题：

    The beautiful mountain village__________ we spent our holiday last year is locatedin __________ is now part of Guangxi.

    A.which ; where
    B.where; what
    C.that ; what
    D.when ; which

    答案：B
    解析：
    where在此充当地点状语，what既充当located in的宾语又充当is的主语，本题考查定语从句和名词性从句。mountain village在定语从句we spent our holiday last year作地点状语，故用关系副词where：第二个考查宾语从句，从句中缺少主语，故用what作主语。故选B。

  • 第5题：

    Tango is a passionate dance, _____________brings the dancers together in a way _____________ words can′ t express.

    A.what; /
    B.which; how
    C.it; in which
    D.which; /

    答案：D
    解析：
    考查定语从句。句意为“探戈是一种热情奔放的舞蹈，它以一种难以用语言表达的方式把跳舞者聚在一起”。第一个空引导非限制性定语从句，修饰先行词dance，且关系词在从句中作主语，故用 which；“___________words can’t express”为定语从句，修饰way，关系词可以用that或which，或者省略不填。本题答案为D。
