参考答案和解析
正确答案：D
解析：译文：结构CobeginStatement1;Statement2;Coend的含义是语句1和语句2并行执行。结构中的两个原子操作是加载一个变量的值和存储一个变量的值。【程序段】x=0;y=0;cobegin{x=1;y+=x;}{y=2;x+=3;}coend执行后，变量的值可能是哪个?先执行第二句再执行第一句，结果是Ⅱ，否则结果是Ⅲ。

    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。
