关于increase的用法

Fabulous

前两天在书上看到这样的一道题

As evidence of sushi's drastically increasing popularity, the most recent studies show that the number of sushi restaurants in the state increased by more than 3 times in the past 5 years.

A   increased by more than 3 times

B   increased by more than triple

C   was increased more than 3 times

D   has more than tripled

E   was more than tripled

答案给出的是D，我当时看得时候觉得选A

后面给出的解释上写着 a number doesn't increase by more than 3 times.是说主语是数量，不能用increase by吗？应该可以把？那么是3 times有问题吗？

可能这不是一本像OG一样很权威的书，但是看到这题我就对于Increase，X times, double, triple 等的用法很是困惑，请帮忙解答一下可以吗？

谢谢！

要说two times时, 最好用twice/double
要说three times时, 最好用triple

这是一个更优原则吗？

不是two times之类的本身的错误吗？

这应该用完成式

D最简洁，符合简洁原则！

double ，triple等词只有主动。。。不能被动！

increase一般做名字的几率比较大，have an increase in sth

umm...
在表倍增的情況下, double/triple/etc會比較好, 因為很清楚知道是什麼在倍增.
A的increased by more than 3 times不是很清楚, 3 times of what?

有点不太理解楼主说的话，可能是我太笨了……

我怎么觉得A的more than 3 times就是形容未划线部分的number的。

the number increased by 3 times这样的用法对吗？

再问！

sorry, 修正:
"be more than 3 times"後要接名詞 or "of what..."
"increased by more than 3 times"後可以不用接任何東東.
so yes, "more than tripled"比"increased by more than 3 times" concise.
