28题语法题，选E是不是又有新的说法拉？GMATPREP语法已经给出答案了D。请大家查看prep语法笔记SC1第13题。PDF格式的，我贴不上来。 另外，22题那个逻辑题ankle fracture到底答案是B是C呢？有NN给个答案吗？ 24-22 Often patients with ankle fractures that are stable, and thus do not require surgery, are given follow-up x-ray because their orthopedists are concerned about possibly having misjudged the stability of the fracture. When number of follow-up x-rays were reviewed, however, all the fractures that had initially been judged stable were found to have healed correctly. Therefore, it is a waste of money to order follow-up x-rays of ankle fracture initially judged stable.
Which of the following, if true, most strengthens the argument? A) Doctors who are general practitioners rather than orthopedists are less likely than orthopedists to judge the stability of an ankle fracture correctly. B) Many ankle injuries for which an initial x-ray is ordered are revealed by the x-ray not to involve any fracture of the ankle. C) X-rays of patients of many different orthopedists working in several hospitals were reviewed. D) The healing of ankle fractures that have been surgically repaired is always checked by means of a follow-up x-ray. E) Orthopedists routinely order follow-up x-rays for fractures of bone other than ankle bones. 另外41题那个语法题，不是只能选单数the ant吗？ft，因为最后那个没划线的it没有单复数一致。我再贴一下题，盼NN解答！不过这个题我做过，但是忘了是GWD的哪一套了？讨论贴也找不到了，太郁闷了。 24-41 In California, a lack of genetic variation in the Argentine ant has allowed the species to spread widely; due to their being so genetically similar to one another, the ants consider all their fellows to be a close relative and thus do not engage in the kind of fierce intercolony struggles that limits the spread of this species in its native Argentina. A) Due to their being so genetically similar to one another, the ants consider all their fellows to be a close relative and thus do not engage in the kind of fierce intercolony struggles that limits B) Due to its being so genetically similar the ant considers all its fellows to be a close relative and thus does not engage in the kind of fierce intercolony struggles that limit C) Because it is so genetically similar, the ants considers all its fellows to be a close relative and thus does not engage in the kind of fierce intercolony struggles that limits D) Because they are so genetically similar to one another, the ants consider all their fellows to be close relatives and thus do not engage in the kind of fierce intercolony struggles that limit E) Because of being so genetically similar to one another, the ants consider all their fellows to be a close relative and thus do not engage in the kind of fierce intercolony struggles that limits 这个its和谁对应？ |
