[解析]
(1)推理判断题。根据第一段About 15 years ago,Andrew McLindon,a business owner,was riding his bike in Austin,Texas,when he thought about a friend's 12﹣year﹣old son.The boy had never known the joy of biking because he suffered from a brain condition that often caused balance disturbances(大约15年前,企业主安德鲁•麦克林登在得克萨斯州奥斯汀骑自行车时,想起了一位朋友12岁的儿子。这个男孩从来不知道骑自行车的乐趣,因为他患有一种经常导致平衡紊乱的大脑疾病);以及第二段的When he got home,McLindon,now 60,went online and found a three﹣wheel recumbent( 侧卧的)bike with a seat belt,perfect for a child with balance issues(回到家后,现年60岁的麦克林登上网发现了一辆侧卧的,带安全带的三轮摩托车,非常适合有平衡问题的孩子),可知想帮助一个有平衡问题的男孩的渴望激发了安德鲁•麦克林登在网上寻找一辆特殊的自行车,故选D。
(2)细节理解题。根据第二段的Soon the boy was cycling around the street with his peers,having fun and getting exercise(很快,男孩就和同龄人一起在街上骑自行车,玩得很开心,锻炼身体),可知自适应自行车可以提供锻炼和乐趣,故选B。
(3)细节理解题。根据第三段的That smile launched the McLindon Family Foundation.Funded by donations,the group works with pediatric rehab(小儿康复)clinics to find children who can benefit from owning bike and to help craft each bike to the particular needs of the child(这个微笑引发了麦克林登家庭基金会的成立。该基金会由捐款资助,与儿科康复中心合作,寻找可以从拥有自行车中受益的儿童,并帮助制作每辆自行车以满足儿童的特殊需求),可知麦克林登家庭基金会的成立是为了给残疾儿童提供合适的自行车,故选C。
(4)推理判断题。根据最后一段 So far,the foundation has given away 450 bikes,and that's just a start."I do a lot of things.I run a lot of companies." McLindon says."But getting these kids their bikes is the most important thing that I do"(到目前为止,该基金会已经赠送了450辆自行车,这只是一个开始。"我做了很多事情。我经营着很多公司。"麦克林登说。"但让这些孩子骑自行车是我做的最重要的事情"),可知麦克林登认为他在麦克林登家庭基金会的工作是值得付出努力的,故选A。
