形容词倍数的三种表示方法

倍数表示法
a. 主语+谓语+倍数（或分数）+ as + adj. + as。例如
I have three times as many as you. 我有你三倍那么多。
b. 主语+谓语+倍数（分数）+ the size （amount，length…） of…。例如：
The earth is 49 times the size of the moon. 地球是月球的49倍。
c. 主语+谓语+倍数（分数）+ 形容词（副词）比较级+ than…。例如：
The grain output is 8 percent higher this year than that of last year. 今年比去年粮食产量增加8%。
d. 还可以用by+倍数，表示增加多少倍。例如：
The production of grain has been increased by four times this year. 今年粮食产量增加了4倍。

看错题目了：1 as + 倍数+as
2 two(three,four ...)times as
3 将要表达的倍数减一然后 +times more than
