题目内容
Americans eat ___ vegetables per person today as they did in 1910.
A. more than twice B. as twice as many
C. twice as many as D. more than twice as many
D
【解析】
试题分析:考查倍数的用法。表示“……是……倍”,由“倍数+as +形容词+ as +”结构组成。as many as和…一样多,但由后文as they did中出现了as,与C选项as many as重复。句意:今天的美国人每人吃蔬菜的量,是他们在1910年吃的两倍多。故选D
考点:考查倍数的用法。
