考题讲解

题目分析:
略。

选项分析:

A选项:本选项具有较强的干扰性。考点的位置出现在cost的定语to meet environmental regulations。在讲清这个考点之前,请允许我先讲清这个选项没犯错误的地方。
首先,用不定式to meet environmental regulations作cost的定语是没有问题的(这个不定式反而不应该修饰industry,因为,我们常说,达到环境标准所花费的成本),不定式中的meet的逻辑主语并非一定要是它的先行词。英语中,不定式作定语时,先行词和其的关系可以是最常见的主谓关系,例如:
We need someone to help with my gmat. (someone will help).
也可以是动宾关系或同位关系,例如:
I have many letters to write. (to write letters)(动宾关系)
We have made a plan to learn from Mary. (此时不定式和plan是一回事,两者是同位关系)
本选项中,先行词cost和定语to meet environmental regulations属于同位关系。
其次,在所有格的表达中,一般地,当人是物主时,用’s或of,物是物主时,用of。例如: 我们通常不说,table’s legs,而说,legs of table。但是,本选项中给出的物主是the United States petroleum industry,这个词我们可以认为是物,也可以认为是一种拟人化的说法,表示这个工业的人们,因此,本选项中用了’s来表示所有格,不能认为是错误的。
那么,这个选项究竟在何处出错了呢?实际上,虽然cost to do和cost of doing在语法上都是正确的,但是在不同的语境下,我们会用不同的写法。本题中这点考查了不定式和ing的区别。用之于本题,主句“石油工业达到环保标准的价格被预期为10分/桶”不直接影响“达到环保标准”这件事的发生与否(是否预期了达到环保成本的价格,不代表日后就会达到环保成本,也不会对“达到环保成本”这件事有什么影响)。因此,本题只能用of doing做cost的定语

B选项:Correct. 本选项在语法和逻辑上均是正确的。of meeting environmental regulations可以跳过to the United States petroleum industry而修饰cost。

C选项:本选项的by the end of the decade是状语,依就近修饰原则,其会修饰动词is projected。但是,在逻辑上,is projected(预估)发生的时间应该是现在,而真正到年末才会发生的应该是成本上涨这件事。

D选项:to meet environmental regulations在本选项中由于位置处于句首,并且同其主句见用逗号隔开,因此其是主句的状语(目的状语)。但显然地,估计(is estimated)的目的肯定不是达到环保标准。

E选项:不定式短语to meet environmental regulations错误同(A)。
