解析
倍数表达要牢记,倍数表达法是高中英语教学的重点,也是历届高考的热点。当我们要表达甲是乙的几倍时,通常用句型来表示:
1. “A+倍数+形容词或副词比较级+than+B”,表示“A比B大(长、高、宽等)多少倍”
This rope is twice longer than that one. 这根绳子是那根绳子的两倍长(比那根绳子长一倍)。
2.“A+倍数+as+形容词或副词的原级+as+B”,表示“A正好是B的多少倍”。如:
Asia is four times as large as Europe. 亚洲的面积是欧洲的四倍。
3. “A+倍数+the size/height/length/width, etc+of+B”,表示“A正好是B的多少倍”。如:
This street is four times the length of that one. 这条街是那条街的四倍长。
4. “……times+what+从句”。如:
The production is now three times what it was ten years ago. 现在的产量比十年前增加了两倍。
本题考察了第2种结构“A+倍数+as+形容词或副词的原级+as+B”,表示“A正好是B的多少倍”,后面省略了as B。故D正确。
考点

序数词的概念:
表示顺序的数称为序数词。如:first, second, third, fourth。
序数词的构成与用法:

②下面这些基数词在变为序数词时,有特殊的变化。
例:one→first
two→second
three→third
five→fifth
eight→eighth
nine→ninth
twelve→twelfth
③十位整数序数词的构成方法是将基数词的词y变成i,然后再加eth。
例:twenty→twentieth
thirty→thirtieth
forty→fortieth
ninety→ninetieth
④两位或两位以上的基数词变成序数词时,仅将个位数变成序数词。
例:twenty-one→twenty-first
thirty-five→thirty-fifth
a hundred and fifty-three→a hundred and fifty-third
2、序数词的用法:
①序数词在使用时,一般加上定冠词。

hree hundred people 三百个人
分数词的构成和用法:
1)分数词构成法:
分数词(FractionalNumerals)由基数词和序数词构成,基数词代表分子,序数词代表分母。除了分子为1的情况下,序数词都要用复数形式:
如:1/4:one-fourth
5/9:five-ninths
2/3:two-thirds
17/5:three and two-fifths
7/12:seven-twelfths
379/8:forty-seven and three-eighths
