A of B as much as A of C.可以把后边的A of 省略么?
,but the prices of them are twice as much as that of ordinary ones.
就是把that of省略变成,but the prices of them are twice as much as ordinary ones.
▼优质解答
答案和解析
that of 不可以省略
必须清楚比较的是什么,本题比较的是 the prices
that 就是指prices
如果你把that of 去掉了,就变成the prices of them 和 ordinary ones 比较了,不对等,是错误的.
另一个改法:可以在ones后面加',表示ordinary ones' prices.
即:but the prices of them are twice as much as ordinary ones'.
