    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。
