  • 第1题：

    In some countries, _____ is called "equality" does not really mean equal rights for all people.

    (A) which (C) that

    (B) what (D) one

     

     


    选B


    这句话貌似定语从句。而实际上，前面的部分就是状语，后半句与countries没有修饰关系（因为1.后半句缺主语，但空格的位置用countries不能替换，否则语义不对。2.后半句不缺宾语。）所以后半句的（)is called equality作主语.是主语从句。
    在选项中，只有what引导主语从句。
    意思：在一些国家里，所谓平等，并不意味着所有公民的平等权利

  • 第5题：

    It's said that he's looking for a new job, one_________ he can get more free time.

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

    答案：B
    解析：
    考查定语从句。one是a newjob的同位语，同时one是先行词，后面是个定语从句，由于定语从句he can get more free time不缺少任何成分，说明空格处在从句中作状语，需要用where引导，意为“从新工作中获得更多的自由时间”。如果选which的话，应该是one(a job)from which he can get more free time，故选B。
