A B fast 修饰 rate不是可以的
表示倍数
two times + 名词
tow times as 形容词 as
表示超过多少，在前面两个结构前面加more than

没有tow times +比较级+than的用法

也就是说倍数之后只可以用as……as结构,那么数词之后都可以用吗？比如：YM is 20 taller than KB.
"表示超过多少，在前面两个结构前面加more than"这个不太明白，可以举出例子吗？

谢谢解答哦~

呵呵，例子倒不用

你可以这么理解

倍数表示出来的都是一个确定的数

你把整个词组看成一个单位

more than修饰整个词组

哦，这样子

18.Since 1970 the number of Blacks elected to state and federal offices in the United States has multiplied nearly four times.
(A) has multiplied nearly four times
(B) has almost quadrupled
(C) has almost multiplied by four
(D) is almost four times as great
(E) is nearly fourfold what it was
这个选B，我最近总是对这种倍数的题搞的很无措呀

我怎么觉得 倍数＋比较级 ＋than的用法在哪里见过呢？相当于 倍数修饰比较级， 我个人觉得不是D错误的所在，而是 that of the 1970's 和前文不平行的原因。

为什么不平行呀the rate of increase was two times faster than that of the 1970's
不过我看了很多帖子，说twice 比two times 好，不知道为什么
