4. The passage implies that
A it is not easy to persuade manufacturers to adopt the new design
B. the team of engineers has not found any countermeasures
C. children like to ride bicycles at a very low speed
D a lot of children were killed in bicycle accidents in the past 30 years
4．A． 分析；該題問及從文章中能夠推斷出什么來，在論述文中往往在文章的開頭和/或結(jié)尾處傳遞出文章的中心/觀點(diǎn)，因此注意文章結(jié)尾(文章開頭的語(yǔ)句與被選項(xiàng)都沒有關(guān)系)：The team has also approached the US consumer Product Safety Commission to try to persuade manufacturers to adopt the new design.（該句表明B錯(cuò)誤） A decision is expected later this year. 該句說“試圖說服制造商”，因此推測(cè)出“說服制造商”不是一件容易的事情。
5. The new handgrip（手柄） works in which of the following ways?
A. it can be commercialized
B. it reduces the dangerous forces in bicycle accidents
C. it adds a few dollars to the cost of a bike
D. it changes the direction of the handlebars in an impact
5．分析：根據(jù)解答前面問題獲取的信息：--傷害孩子的是把手的末斷，因此推斷B和D可能是答案。利用題干中的核心詞handgrip作為答案線索，這樣找到答案相關(guān)句：The solution the group came up with is a handgrip fitted with a spring and damping system. The spring absorbs up to 50 percent of the forces transmitted through the handlebars in an impact. 這兩個(gè)句子說“手柄的彈簧能吸收在碰撞中通過把手而傳遞過來的50%的傷害力”，因此判斷B是答案。
