Question

    Every summer, my family and I visit our relatives in India and whenever we travel, my parents always remind me to drink only bottled or boiled water. On one of my trips to India, I saw children drinking water from the roadside. I was troubled to learn that millions of people, most of them children in developing countries, die each year because of water related diseases.

Living in the US, I am lucky to be able to turn on the tap and get potable water(饮用水), while one sixth of the world's population lacks access to clean water This year, I entered the Discovery Education 3M Young Scientist Challenge. In late June, I learned that I was selected as one of the top 10 national finalists of this famous middle school science competition. Over the summer, I worked with Dr. Jim Jonza, my Scientist mentor( 导 师 )from 3M, and developed a system that uses solar energy to purify water. My invention is green and cost effective, and I am looking forward to implementing this in places that are affected(影响)by harmful water pollution.

In October, my family and I flew to 3M Headquarters in St Paul, Minnesota, where the final event was to be held.  For the last challenge, each of us had to present the invention we had been working on over the summer. The first place winner would win $25,000, a trip to Costa Rica, and the title of America’ s Top Young Scientist. At the awards ceremony, all of us waited anxiously until one of  the judges, Danny Forester, started announcing "The winner of the Discovery Education 3M Young Scientist Challenge is.... “ You could hear a pin(大头针) drop as he opened the paper with the winner’ s name, “Deepika Kurup!”

As America’s Top Young Scientist, I was given an opportunity to show my invention on national television and deliver several presentations. One of the most important things I have learned is that communication and teamwork are key to success.

【解析】

这是一篇记叙文。作者通过一次去印度的经历，发现人们缺乏清洁水，就此得到启发回国后与Jim Jonza博士合作，开发了一个利用太阳能的净水系统。并在去年10月，和家人飞往3M位于明尼苏达州圣保罗的总部，用自己的发明赢得了第一名以及美国顶尖青年科学家的称号。

1.推理判断题。根据第一段最后一句I was troubled to learn that millions of people, most of them children in developing countries, die each year because of water related diseases.（我获悉，每年有数百万人死于与水有关的疾病，其中大多数是发展中国家的儿童。）描述可知作者提到自己去印度的经历是为了说明人们缺乏清洁水的问题。故选B。

2.词义猜测题。根据My invention is green and cost effective可知implementing是应用的意思。

3.细节理解题。根据You could hear a pin(大头针) drop as he opened the paper with the winner's name可知Forester宣布获奖时，所有观众都屏住呼吸，你甚至可以听到大头针落地的声音。可知观众都非常安静地坐着，故选C。

4.推理判断题。根据全文可知，作者主要按时间顺序回顾了自己在发现教育3M青年科学家挑战赛中夺冠的经历。故选A。
