问题共用题干 Pushbike Peril

Low speed bicycle crashes can badly injure or even kill children if they fail onto the end of the handlebars（自行车把手）.______(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 showed 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.

选项 _________（50） 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.

答案 B

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，即低速行驶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。
本题考查的是对上下文之间的意义关系的理解及对文章主旨的把握。第二段主要介绍了以生物学工程师克里斯蒂为首的研究小组开始对不合理的车把手进行重新设计。空格（47）的内容其实是这一段的主旨，说明了该研究小组的目的和任务。从这一点判断，选项A是合适的选择。
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。第三段有两个空格，相对来说有一定难度。空格（48）前面一句介绍了该研究小组的研究方法，即采访伤者和重现现场，因此空格（48）顺理成章地应该是研究的结果。选项F开始的两个词they discovered就说明了这一点，故选F。
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。
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。解答此题关键要看下文，在下一句中，研究员说现在的任务是使大多数的自行车制造商意识到这个问题，我们可以推知空格（50）就是时这个问题的陈述，即如何能使这种装置商业化。其实最后一段说研究员还联系了美国消费者产品安全协会，希望能说服制造商接纳这一设计，这也是该空格选B的原因。
