A. as
B. than
C. that
D. of what
E. at which
答案:C
不明白的地方就是我看prep08的解释,说that指代的是price. 而D选项,则说错误原因是因为what指代的是price,代换一下就变成了price of price,导致了重复。可是我想的是B和D的选项是一个道理啊,都是指代了price,那为什么D就是重复,B就不构成重复呢??而且B选项中的that在从句中充当的又是什么成分呢??求大家帮忙解答一下啊~~~谢谢大家了~~
B选项是than,lz是不是想比较一下C和D?
C选项that这里引导定语从句,这里that作为关系代词指代 price。而 D选项中what在定语从句中作为关系代词,前面是不能有先行名词的,也就是说 what在本句中就相当于 price that 那么如果前面再有先行词 price就变成了 the price of price that,这就重复了。所以D错。
这是基础语法知识,LZ还需努力学习。
