B
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 waterrelated 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 learnt 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 costeffective, and I am looking forward to implementing this in places that are affected 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 learnt is that communication and teamwork are key to success.
5．Why does the author mention her visits to India?
A．To express her great love for India.
B．To show the problem of unclean water.
C．To explain the importance of relatives.
D．To compare eastern and western cultures.
6．Which of the following can replace the underlined word “implementing” in Paragraph 2?
A．Researching. B．Changing.
C．Finishing. D．Using.
7．How did the audience react as Forester opened the paper with the winner's name?
A．They appeared calm.
B．They let out shouts of joy.
C．They sat quietly.
D．They dropped pins to the author.
8．How is the text mainly organised?
A．In order of time.
B．In order of complexity (复杂性)．
C．In order of place.
D．In order of importance.
5．B 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 waterrelated diseases.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项。
6．D 词义猜测题。根据My invention is green and costeffective可知作者有了某项发明，再由画线词后的内容可知作者希望自己的发明用到有水污染的地方，故implementing是“应用”的意思。
7．C 细节理解题。根据You could hear a pin drop as he opened the paper with the winner's name可知，宣布获奖名单时，你甚至可以听到大头针落地的声音。由此可知，观众都非常安静地坐着，故选C项。
8．A 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探索教育3M青年科学家挑战赛中夺冠的经历。故选A项。
