Pushbike Peril
Low speed bicycle crashes can badly injure or even kill children if they fall onto the end of the handlebars (自行车把). (46)
Kristy Arbogast, a bioengineer (生物工程师) at the Children’s Hospital of Philadelphia in Pennsylvania, began the project with her colleagues after a study of serious abdominal(腹部的) injures in children in the past 30 years and showing that more than a third were caused by bicycle accident. (47)
By interviewing the children and their parents, Kristy and her team were able to reconstruct many of the accidents and identified a common mechanism responsible for serious injuries. (48) To maintain their balance they turn the handlebars through 90 degrees, but their momentum (动力) forces them into the end of the handlebars. (49)
The solution the group came up with is a hand grip (握柄) fitted with a spring and damping (缓冲) system. The spring absorbs up to 50 percent of the forces transmitted through the handlebars in an impact. (50) "But our task has been one of education because up until now, bicycle manufactures were unaware of the problem, " says Kristy.
The term has also approached the U. S. Consumer Product Safety Commission to try to persuade manufactures to adopt the new design. A decision is expected later this year.
A. The task according to Kristy was to identify how the injuries occurred and to come up with some countermeasures (对策).
B. The group hopes to commercialize (使商业化)the device, which should add only a few dollars to the cost of a bike.
C. So a team of engineers is redesigning (重新设计) the humble handlebar in a bid to make it safer.
D. When the task is over, the engineers believe, there are probably no such injuries or tragedies among bicycle-drivers.
E. The bike then falls over and the other end of the handlebars hits the ground ramming it into their abdomen.
F. They discovered that most injuries occur when children hit an obstacle at a slow speed, causing them to topple over.
选项
答案
E
解析
本题考查的是对上下文之间的意义关系的理解及对文章细节的把握。我们在上题说过,空格(48)和(49)在一定程度上是有联系的,都是该小组的研究发现结果。空格(49)前面一句是研究者对导致受伤的情形的事后重现,空格(49)顺承前一句,完成了研究者的现场重现。选项E的第一个词then是一个关键词,表明了这种顺承关系故选E。
