歌德巴赫猜想（大全505）

找到了OG110给大家参考一下：

        It has been estimated that the annual cost to the United States of illiteracy in lost industrial output and tax revenues is at least $20 billion a year.

(A) the annual cost to the United States of illiteracy in lost industrial output and tax revenues is at least $20 billion a year

(B) the annual cost of illiteracy to the United States is at least $20 billion a year because of lost industrial output and tax revenues

(C) illiteracy costs the United States at least $20 billion a year in lost industrial output and tax revenues

(D) $20 billion a year in lost industrial output and tax revenues is the annual cost to the United States of illiteracy（C）

(E) lost industrial output and tax revenues cost the United States at least $20 billion a year because of illiteracy

这是OG的解释for greatest clarity, cost should be followed immediately by a phrase (e.g., of illiteracy ) that identifies the nature of the cost。

"and thus cost the nation $64 billion in medical expenses and lost work time."

i think that thus may be the subjetct of the verb-cost (not theamericans), and thus means that 18 million americans lose lose 64million workdays a year.

is it reasonable??

为什么不能选E，我认为E中，cost的主语是64 million workdays a year cost...

请问这样的理解可以吗？

E中后面in用的不对.

是说那些得了病的美国人花了多少多少钱...

这样理解好象也附合常规的.

请教NN,如可确定到底是Americans还是Migraine是cost的主语呢？
