In spring 2016, Liza Goldberg asked scientists at NASA's Goddard Space Flight Center if she could do research there.There was a problem, though.She was just 14 years old, and NASA's internship (实习) program only accepts students starting at age 16.
David Lagomasino and Temilola Fatoyinbo are NASA satellite experts.They saw Liza's request.In it, she talked about how she had studied trees in her own backyard to learn about climate change.The two NASA scientists were impressed.“This girl sounds great，” Lagomasino remembers saying.“Let's bring her in.” They made a special role for her outside the internship program.
Lagomasino and Fatoyinbo thought Liza could help them use satellite data to map mangroves, a small tree that grows in muddy forests on the coastlines of many tropical (热带的) countries. Mangroves are very important as they store huge amounts of carbon, which makes them helpful for fighting global warming.They are also home to fish that millions of people depend on for food.
Less than two years later, Liza has developed what might be the world's first satellitebased system to determine where mangroves are in trouble. The work uses data from four satellites.It covers mangrove growth and loss, rainfall, agriculture and city growth.
Lagomasino and Fatoyinbo brought Liza in during the summer before she started high school. The teen had seen mangroves only once before, during a trip to Fort Myers, Florida.Soon, she would see many more, at least on her computer screen.
Liza learned that half of the world's mangroves had disappeared.She was shocked and motivated to do something.“I wanted to create some kind of solution，” she said.She would even work during school breaks or at home on her projects.Liza's hard work is starting to pay off. Already, environmental groups are eager to use her system to make their work more effective.
Now that she has turned 16, Liza has finally joined NASA's official internship program.
语篇解读：本文是一篇记叙文。14岁的Liza进入NASA开始进行科学研究，其成果对保护生态植物红树林很有帮助。
1．Why was Liza outside the internship program at first?
A．She didn't meet the required age.
B．She didn't show her talent properly.
C．She knew little about global warming.
D．She lacked the experience of datacollecting.
解析：选A 细节理解题。根据第一段的最后一句可知，Liza没有达到年龄要求，所以没有进入这个实习项目。
2．Why are mangroves so important?
A．They are food for fish.
B．They are commercial crops.
C．They forecast climate change.
D．They keep a balanced ecosystem.
解析：选D 细节理解题。根据第三段中的“Mangroves are very important ...people depend on for food.”可知，红树林在维持生态平衡方面起到很大作用。
3．What does the underlined word “It” in Paragraph 4 refer to?
A．The satellite. B．The data.
C．The system. D．The work.
解析：选 B 代词指代题。根据画线词上一句“The work uses data from four satellites.”及画线词所在句可知，It在此处指“收集到的数据”。
4．Which of the following can describe Liza's work in NASA?
A．It is fruitful.
B．It earned her fame.
C．It took up her school time.
D．It will lead to a future job with NASA.
解析：选 A 推理判断题。根据倒数第二段的最后一句可知，Liza所设计的系统有望使环保机构的工作变得更高效。由此可知，Liza在NASA的工作是卓有成效的。
