问题
选择题
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
答案：C
题目分析：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。
