Question

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

Answer 1

答案D
more than twice表示倍数，放在as…as结构前，意思是“是……的两倍多”。题干意思为：“美国人现在每天所吃的蔬菜是1910年的两倍多。”此题显然是考查倍数的表示法。more than twice并没有错，尽管我们通常见到twice more than，在这里是more than(超出)来修饰twice。此题易错选择C，题于中today后已经有了一个as，如果选择C则多出了一个as。
