    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C
解析 本题考查的是对上下文之间的意义关系的理解。文章的开头提出了一个严重的问题，即低速的脚踏车撞击地面也能造成儿童的严重损伤甚至死亡。从第二段开始，我们看到工程师们已经在着手开发一个新设备来解决该问题，所以空格(46)的内容应该是起到承上启下的作用，选项C的意思正好满足这个要求，故选C。
