选择题
Everybody needs calcium, but it is quite possible for a similar person to be totally healthy by eating only________.
A．as half much
B．as much half
C．half as much as
D．half as much
答案
答案：D
考查倍数表达。该句运用的是“倍数＋as＋...＋as＋比较对象”结构，eating only后面部分的完整表达应为half as much calcium as the other person eats。其省略形式为half as much，故选D项。
