正确答案为B
不解的是为何需要把原选项的“projected"改为”estimated“
这一题cost以被动方式描述就不好么？
另外B中的用法cost to the United States petroleum industry of meeting environmental regulations总觉得别扭，是否用限定性定语从句来修cost更好些？
选D有何错误？
谢谢斑斑~

嗯，B里面也可以用Projected. it is projected that也是对的，比如:It is projected that Canary Wharf will become a Wall Street on water, serving an expanding financial center hard-pressed for space in the mile-square City of London, and provide up to 60,000 jobs.

industry's cost或cost of industry  工业的价格
the cost to the industry   工业成本
原来需要这样理解，感谢斑斑

也就是说project +A +B，省略that这种用法才是地道的，那么如果正确答案B中的estimate换作是project也一样正确是么？都是“估计”的意思阿（宾从引导词that不省略）
另project的这种用法和estimate / believe / announce + AB 是一个道理吧？

呵呵，还是对这个换词有点纠结

industry's cost或cost of industry  工业的价格
the cost to the industry   工业成本

Project在这里是估计的意思：
【CALCULATE】 [T]
to calculate what something will be in the future, using the information you have now
　 The company projected an annual growth rate of 3%.
所以可以发现,be projected后面不应该跟at，否则unidiomatic.

B the best Choice A, C, D, and E are awkward and confusing. In A, for example, the issue is not the industry’s cost but the cost to the industry; also, to meet should be of meeting here, projected at is unidiomatic, and by the end of the decade is placed so that its meaning is unclear.

C and D suffer from many of the same problems.

The wording of E implies that cost… is estimated in order to meet environmental regulations.

B alone makes a logical statement and varies verb tense to indicate that the issue is present estimates of future costs. The question is moderately difficult.
