问题 According to the passage, some engineers are trying to improve the handlebars because ______.
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 be
D、to tell us why Kristy Arbogast began the project

答案D

解析 利用题干中的核心结构serious abdominal injuries作为答案线索,问题问及目的,所以注意段落中表示目的的句子/结构,这样找到答案相关句:Kristy Arobogast,a bioengineer at the Children’s Hospital of Philadelphia in Pennsylvania began the project with her colleagues after a study of serious abdominal 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 injurie soccurred and come up with some countermeasures.该划线结构表示目的,其含义是“辨别受伤是怎样产生的,并想出一些应对措施”因此判断A和C错误。在前面的划线结构的主要内容是“Kristy Arobogast开始做这个项目是在一项研究有了结果以后,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源于自行车事故。”因此判断D是答案 (告诉我们为什么Kristy Arobogast开始这个项目)。
