第5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
