Which of the following most logically completes the passage?
Most bicycle helmets provide good protection for the top and back ofthe head, but little or no protection for the
temple regions on the sides ofthe head. Astudy 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) amongthe 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
答案:D
我的自己的逻辑链是这样的:大多数自行车头盔对头顶部和后部的保护很好,但是几乎没有对temple区域的保护→对自行车事故中头部受伤的研究表明:很大一部分是由于temple区域的冲击→因此,如果头盔能够保护temple区,自行车事故中头部严重受伤的风险就会大大降低, especially since_____________
问题1 : especially since在这里到底什么意思,是“尤其因为”还是“尤其当”,前面已经有therefore了啊。
问题2:非常不理解的思维:根据前面的背景和条件:1 没有对temple区的保护 2 很多是temple区受冲击 很自然就能推出“保护该区就能降低风险”的结论。为什么要选个答案说:这个区域的头骨很薄,容易导致头部受伤 呢?
问题3: head injury 和 serious head injury 一字之差 会不会是这题的关键点?我唯一能想到的就是这个。
求大家不吝赐教,如此简单的题,我就是不懂。
