问题补充:
Nowadays we take exercise a day as we need because of widely used automobiles.
A. less than half
B. less than as half as
C. less than half as much
D. half less than
答案:
A. less than half
B. less than as half as
(答案→)C. less than half as much
D. half less than
解析:句意:现在因为广泛使用汽车,我们一天的锻炼不到需要的一半。这里使用的是倍数的表达法:倍数+as+adj+as,这里half就是倍数,less than是修饰half的,所以放在前面,因为横线后面有as了,所以用as much,选C。
