解题思路： 见下
解题过程：
我认为答案是C
这是2个念头比较，the year before应该不加in介词才对。所以C比B好。那么，倍数的表达法是什么呢？
一、As……as……表比较的句型：
A……＋倍数/分数/百分比＋as＋adj/adv＋as＋B （A、B代表2个被比较的事物或人）关键是记住必须把相差的倍数或百分比放在as……as的前面。
例：This road is twice as long as that one.
(2005湖北卷)What a table! I’ve never seen such a thing before. It is__it is long.
A half not as wide as B wide not as half as
C not half as wide as D as wide as not half （C）
但是，在实际表达和考题中， 这个句型经常有变形。变形情况如下：
1、 A……＋倍数/分数/百分比＋as＋adj＋n＋as＋B
（02上海春季卷）American 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)
（04广西卷）It is reported that the United States uses ___ energy as the whole of Europe.
A as twice B twice much C twice much Dtwice as much (D)
2、 A……＋倍数/分数/百分比＋as＋adj＋a（n）＋n＋as＋B
During the season all the animals are sold at twice as high a price as usual. 在这个季节，所有的动物的售价都是平常的2倍。
(NMET2001)It is generally considered that teaching is _____ it is a science.
A an art much as B much an art as C as an art much as D as much an art as （D）
3、 A……＋倍数/分数/百分比＋as＋adj＋n（省略第2个as）
The USA has more than 14 times as many people(as Australia). 美国的人口数量是澳大利亚的14倍还多。
（03上海卷）The house rent is expensive. I’ve got about half the space I had at home and I’m paying ___ here.
A as three times B as much three times
C much as three times D three times as much (D)
这里房租很贵。在家里住的一半大小的面积在这里要付2倍的价钱。后面省略了as at home。
二、你所说的3种说法as没有，可能是表比较的3个方法吧？ As……as算一种，以下还有2种。记住无论哪种，必须把相差的倍数或百分比放在前面。
1、 A……＋倍数/分数/百分比/具体数字＋adj/adv的比较级＋than＋B
This road is twice longer than that one. 这条路比那条长2倍。
He is two years older than I. 他长我2岁。
2、 A……＋倍数/分数/百分比＋the＋n＋of＋B
（05上海卷）At a rough estimate, Nigeria is ____ Great Britain.
A three times the size as B the size three times of
C three times as the size of D three times the size of (D)
这个句型也有很多变形：
1） A……＋倍数/分数/百分比＋the/物主代词＋n
He is double my age.
2） A……＋倍数/分数/百分比＋what从句
If you offered me six times what you have just offered, I would still take my pound of flesh.
