help--"there are twice as many X as Y"

I just noticed that I forgot to mention about the orginal question, here it is:

twice as many x as y: "twice as many x" and "as y" are the two things that are being compared, so in a way, "2x" and "y" are the same;

as for "more than twice as many x as y", if we use "more than" that means something is more than something else, there is not equality here, so "more than twice as many x" and "as y" are once again the two things that are being compared, so "something more than 2x" => ">2x" and "y" are the same, thus y > 2x

这样的话，岂不是和上面的题目做法矛盾？

(1)    The farm has more than twice as many cows as it has pigs.

see the way i solved the problem is based on the fact that "the farm has more than twice as many pigs as it has cows", are you sure above is what the orginal problem says?

这是一道GWD题，有很多人讨论过的，我是直接把题目copy过来的，应该没有错。。。

btw，我一直觉得twice as many x as y中的twice是修饰y的。。。

我刚刚google了一把，找到了QYQ书上的描述：twice as many A as B, A=2B

虽然觉得流沙说得有些道理,

可我读这句子的感觉,还是y=2x

请nn来确认一下

问了一个考790的牛牛，他很确切的告诉我twice as many x as y中 y=2x。

，我还是想不通，那我给出的例子真的错了吗？

168. Today, because of improvements in agricultural technology, the same amount of acreage produces double the apples that it has in 1910.

(A)  double the apples that it has

(B)  twice as many apples as it did

(C)  as much as twice the apples it has

(D)  two times as many apples as there were

(E)   a doubling of the apples that it did

找了一道OG SC，这题答案B，按照该题的意思，那么表达的应该是X=2Y了。
