15.The computer software being designed for a project studying Native American access to higher education will not only meet the needs of that study, but also has the versatility and power of facilitating similar research endeavors. (A) but also has the versatility and power of facilitating (B) but also have the versatility and power to facilitate (C) but it also has the versatility and power to facilitate (D) and also have the versatility and power of facilitating（B） (E) and it also has such versatility and power that it can facilitate 这次为什么是用have? 主语不是computer software 吗？要是把主语看成needs句意也不通的啊。
Car owners who inflate their tires properly can substantially boost their vehicles’ fuel efficiency, since the increase in car-road friction can waste up to five percent of car fuel by underinflation. (A) Car owners who inflate their tires properly can substantially boost their vehicles’ fuel efficiency, since the increase in car-road friction can waste up to five percent of car fuel by underinflation. (B) Because the underinflation of tires can waste up to five percent of a car’s fuel by increasing car-road friction, car owners can substantially boost their vehicles’ fuel efficiency by properly inflating the tires. (C) Their vehicles’ fuel efficiency is substantially boosted by car owners through the proper inflation of tires that, when underinflated, can waste up to five percent of car fuel by an increase in car-road friction. (D) The proper inflation of tires by car owners, due to the fact that underinflation can waste up to five percent of a car’s fuel by the increase of car-road friction, can substantially boost their fuel efficiency.（B） (E) Because up to five percent of a car’s fuel are wasted through the increases in car-road friction when the tires are underinflated, car owners properly inflating tires can substantially boost their fuel efficiency 这题我就属于纠结于A和B 之间啊，为什么B 比A好呢？原因放句首好？还是因为because优先于since？

第一题，根据语意，是前面的整句话的内容加深了墨西哥的负债压力 第二题，WILL not only meet 表明后面也是用动词原形 ——根据平衡结构原则 第三题 。。。我也不知道。。。怎么解释。同求高人作者: miguel29 时间: 2010-11-20 07:08
好啊，谢谢啦，继续等第三题。。。作者: winny0821 时间: 2010-11-20 08:42
我当时选的时候觉得 who 定语从句不能表明inflate their tires properly是 boost their vehicles’ fuel efficiency的方法 他只是说明了owner的特征 就像owner with a hat 或者 owner who has children 当时觉的表达不effective作者: winny0821 时间: 2010-11-20 08:44
或者说把who....当成修饰成分去掉以后，owner can substantially boost their vehicles’ fuel efficiency逻辑上不合适作者: s2206001 时间: 2010-11-20 10:59
第一题： AB，时态错， During the 1980’s要求主句使用过去时。 C使用 there was 结构，强调客观存在，不恰当。 E，使用 is estimated as having，通常使用to do接动词，as往往接名词。
第二题： will not only meet要求第2分句使用动词原形，排除ACE，D搭配错。
第三题： A使用by underinflation，不合理，因为这个表示做某事情的方式。 C项，inflation of tires不能使摩擦增大，逻辑相违背。 D, their fuel efficiency，指代不清。due to the fact 也不合理。 E项，car owners无法执行动作can substantially boost their fuel efficiency，而且 through the increases 也不能完成费油的动作。作者: kevin0214 时间: 2010-11-20 11:04
限制性定语从句不能去掉，去掉后意思肯定有改变。同样的，E选项中inflating tires 分词作限制定语，相当于一个定语从句。 A的问题是by underinflation不对，用什么方法作要用by doing表示，by+名词表示的是动作的主语，但是这里已经有主语了。作者: miguel29 时间: 2010-11-21 04:23

Car owners who inflate their tires properly can substantially boost their vehicles’ fuel efficiency, since the increase in car-road friction can waste up to five percent of car fuel by underinflation. 我认为是跳过who，Car owners can substantially boost their vehicles’ fuel efficiency 不合理，侧重点应该是 inflate their tires properly的行为去boost
