Pushbike Peril
Low speed bicycle crashes can badly injure or even kill children if they fall onto the ends of the handlebars (车把) so a team of engineers is redesigning the humble handlebar in a bid to make it safer.
Kristy Arbogast, a bioengineer at the Children’s Hospital of Philadelphia in Pennsylvania, began the project with her colleagues after a study of serious abdominal(腹部的) injuries in children in the past 30 years showed that more than a third were caused by bicycle accidents. "the task was to identify how the injuries occurred and come up with some countermeasures(对策). " she says.
By interviewing the children and their parents, Arbogast and her team were able to reconstruct(重建; 重构) many of the accidents and identified a common mechanism responsible for serious injures. They discovered that most occur when children hit an obstacle at a slow speed, causing them to topple over. To maintain their balance they turn the handlebars through 90 degrees — but their momentum (冲力) forces them into the end of the handlebars The bike then falls over and the other end of the handlebars hits the ground, ramming it into their abdomen.
The solution the group came up with is a handgrip(握柄) fitted with a spring and damping(制动的; 减速的,缓冲的) system. The spring absorbs up to 50 per cent of the forces transmitted through the handlebars in an impact, The group hopes to commercialize(使商品化) the device, which should add only a few dollars to the cost of a bike. "But our task has been one of education because up until now, bicycle manufacturer were unaware of the problem," says Arbogast.
The team has also approached the US Consumer Product Safety Commission to try to persuade manufacturers to adopt the new design. A decision is expected later this year.
In paragraph 2, the author mentions a study of serious abdominal injuries
选项
A、to discuss how abdominal injuries in children occur.
B、to show that more than a third injuries were caused by bicycle accidents.
C、to point out what the countermeasures can he.
D、to tell us why Kristy Arbogast began the project.
答案
D
解析
短文第二段提到“克里斯蒂·阿博加斯特是在一项研究有了结果之后开始做这个项目的。这项研究的结果表明在过去的30年里,超过1/3的儿童腹部受重伤的情况起因于自行车事故”。这个研究结果是开始做项目的促动因素之一,故选D。
