Most bicycle helmets provide good protection for the top and back of the head, but little or no protection for the temple regions on the sides of the head. A study of head injuries resulting from bicycle accidents showed that a large proportion were caused by blows to the temple area. Therefore, if bicycle helmets protected this area, the risk of serious head injury in bicycle accidents would be greatly reduced, especially since. (A) among the bicyclists included in the study’s sample of head injuries, only a very small proportion had been wearing a helmet at the time of their accident (B) even those bicyclists who regularly wear helmets have a poor understanding of the degree and kind of protection that helmets afford (C) a helmet that included protection for the temples would have to be somewhat larger and heavier than current helmets (D) the bone in the temple area is relatively thin and impacts in that area are thus very likely to cause brain injury (E) bicyclists generally land on their arm or shoulder when they fall to the side, which reduces the likelihood of severe impacts on the side of the head
正确答案是D。做是作对了，但是看OG的解释有不懂的地方。 OG对E选项的解释是：This is largely irrelevant. Even if it suggests that head injuries do not generally result from bicyclists falling to the side, it does not indicate that such injuries are rare or that there is not great rist of serious injury in those cases in which there is impact to the temple area. 我对OG不理解的在于：选项都说了reduces the likelihood of severe impacts on the side of the head,为什么OG的reasoning还是it does not indicate that such injuries are rare or not serious？是因为可能基数大，所以即使降低了可能性，总次数还是很高（not rare）吗？ 我自己对E的想法是，如果如E所说，那么既然减少了side of the head的可能性，通过戴头盔来减少这个地方受伤 就更没有必要了，没有补充原因，反而weaken了。 不知道我这么想对不对，请大家多多指教啦！作者: Jacksz 时间: 2013-3-21 16:31 Therefore, if bicycle helmets protected this area, the risk of serious head injury in bicycle accidents would be greatly reduced, especially since.
如果保护侧面，那么HEAD INJURY will reduce , 这（划线部分）是因为。。。。。
