as as 的省略问题（求确认）

我记得有个NN按照主语比较，宾语比较的办法分类总结过比较句型。我今天又看这些句子，发现这个方法可以用在as as 的省略问题上。分析如下：

主语比较：
2.More than 3 times as many independent institutions of higher education charge tuition and fees of under $8000 a year as those charging over $16000.
3.Ten times as much petroleun exists in such sources as A, B, and C as （that）in conventional resources.
7.four times as many Americans were killed as （those） would later be killed on the beaches of Normandy during D-Day
 7 我觉得算是复杂主语比较了，参照2句，这里应该省略了those, 但是时态发生了变化。

表语比较：
1.Minority graduates are nearly 4 times as likely as other graduates to plan on practicing in the socioeconomically deprvied areas.

宾语状语（这种比较很严格的，主谓都要补充，补充的时候注意用it， that, those 和do 的使用）：
4.To meet the rapidly rising market demand for fish and seafood, suppliers are growing fish twice as fast as they grow naturally, cutting their feed allotment by nearly half and raising them on special diets
5.The dirt roads cost twice as much to main as paved roads do(=cost).
6.The same amout of acreage produces twice as many apples as it did in 1910.

补 they it 是同类事物比较
   that those 是同类他物的比较
