Question

The cost of a asingle PREC-M,which is about $2,500,000,is_____that of an average ambulance.
A.three times more than B.three times much more
C.more than three times of D.more than three times

Answer 1

首先倍数应该放在形容词前,因为它是修饰词,第二,价格多用more就可以了,more than 比.......多/贵,所以 用A.
C和D的选项倍数不在形容词前,排除,B选项,比较级要有than或as.

Answer 2

A
被数的表达法：

1） A + 谓语+倍数+the +n.(size/ height/ length……)+of B
2） A + 谓语+倍数+as + abj. + as B
3） A + 谓语+倍数+ 比较级+than B
4） A + 谓语+比较级+than B+by+倍数
例如：1).This square is twice the size of that one.
 This square is twice as large as that one.
 This square is once larger than that one.
2).This factory produced three times as many cars as they did 10 years ago.
3).He is 3 years older than I- He is older than I by 3 years

本题符合第三种

Answer 3

A 几倍多的表达就是先表达倍数再表达多
