16.  Factory outlet stores, operated by manufacturers, are usually located miles from downtown and regional shopping centers so as not directly to be competitive against department stores in the same trading area.  
(A) so as not directly to be competitive against  
(B) in order for them not to have direct competition with  
(C) so that they do not compete directly with  
(D) in order that they are not directly competitive against  
(E) for the purpose of not competing directly with  
答案: C.
但是我想E更好，避免了they 指代不清晰。而且记得有道题目和这个很像，最后也选择的是E.


22.  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.  
(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.  

这个是个老题目，但是我还是不理解。答案是B.
其他的，比如，a, c. 也没有发现错在哪里。。。

A的表达不是很有效
Car owners （who inflate their tires properly） can substantially （boost their vehicles' fuel efficiency）
中括号内的两部分被残忍地分开了，好象它们没有关系。其实正是前面导致后面。

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.
不仅没能表达这样的因果关系，而且也很WORDY、UNGRAMMATIC（好比说through the proper inflation of tires that, 修饰谁呢？），而且还UNNECESSARILY使用了被动。
