Americans eat ( ) vegetables per person today as they did in 1996 选项A more than twiceB as twice as many Ctwice as many as希望可以说明原因
选A twice as many
解析:倍数的表达方式之一有:……倍数+as many(或much)+名词+其他+as…,所以选C
倍数表达总结:
1.用形容词表示甲是乙的几倍时,用下面三个句型,用副词表示则一般只用前两个句型.
(1)……倍数+形容词(或副词)的比较级+than
This rope is twice longer than that one.
这根绳的长度是那根绳的三倍.(比那根绳长二倍)
(2)……倍数+as+形容词(或 much)或副词+as
Asia is four times as large as Europe.
亚洲的面积是欧洲的四倍.
(3)……倍数+the size(length,height…)of
This street is four times the length of that street.
这条街是那条街的四倍长.
2.要用名词表示“量”的倍数时,则用以下两个句型:
(1)……倍数+more+名词(可数,不可数)+than
There are four times more books in our library than in yours.
我们图书馆藏书(数量)是你们图书馆藏书的四倍.(我们图书馆藏书比你们的多三倍.)
(2)……倍数+as many(或much)+名词+其他+as…
After the technique was introduced,the factory produced twice as many tractors in 1988 as the year before.
采用新的技术以后,那个工厂1988年生产的拖拉机是前一年(1987年)的两倍.(比前一年增长一倍)
A,B C 都不对。没有D,如果D 选项是twice as many ,则D是正确的。
这是有关倍数的表达问题,词序:倍数+as many(或much)+名词+其他+as…。
