•30. GWD-31-Q30
    

•The United States petroleum industry’s cost to meet environmental regulations is projected at ten percent of the price per barrel of refined petroleum by the end of the decade

A.The United States petroleum industry’s cost to meet environmental regulations is projected at ten percent of the price per barrel of refined petroleum by the end of the decade.

B.It is estimated that （by the end of the decade the cost to the United States petroleum industry of meeting environmental regulations） will be ten percent of the price per barrel of refined petroleum.

C.By the end of the decade, the United States petroleum industry’s cost of meeting environmental regulations is projected at ten percent of the price per barrel of refined petroleum.（It seems that the projection of cost is happening by the end of the decade）
   

D.重心失衡To meet environmental regulations, the cost to the United States petroleum industry is estimated at ten percent of the price per barrel of refined petroleum by the end of the decade.

E.The United States petroleum industry’s cost by the end of the decade to meet environmental regulations is estimated at ten percent of the price per barrel of refined petroleum.

fist of all, by the end of the decade indicates that we should use the future tense
second, cost as a noun has a standard usage : cost to something of doing sth

third, it is estimated that is used appropriately,

A不對因為by the end of the decade會誤修is projected

A、C、E中industry’s cost 用法错误，D中the cost 做主语和To meet……不一致，所以选B

shadow影

1. cost
（1）"industry's cost" or "cost of industry"  工业价格
     the cost to the industry   工业成本
     从属关系用 to，属性关系用 of
（2）美国能源业迎合规定的成本，所以不是cost主动去meet the regulation, 是industry meet the regulation.

所以A.C.E错

2.By the end of the decade,
（1）修饰的是主语Cost，A.修饰Is projected；B.C.E.修饰对了；D.修饰estimated.
所以A.D.错

（2）BY…要求用现在完成时或一般将来时，表达到…之前的情况
所以A.C.D.E错，当然时态是最后考虑的

3.句子重心改变：D.强调了To Meet……

4.综上，所以B对
