A 15 year old scientist and inventor has been named as Time's first ever Kid of the Year.
Rao is a high school student from Colorado. She was chosen from 5，000 U．S. based nominees (提名). Time said in a statement that Rao stood out for her ability to apply scientific ideas to real world problems and her efforts to motivate other kids to take up their own causes. Rao told the Associated Press that the prize is “nothing that I could have ever imagined. And I'm so grateful and just so excited that we're really taking a look at the upcoming generation and our generation, since the future is in our hands.” She insists that starting out small doesn't matter, as long as you're enthusiastic about it.
It's just the latest recognition for the teenager, who was named last year to the Forbes 30 Under 30 list. Rao won praise in 2017 after she developed a portable device (设备) to detect lead (铅) in water. She went on to cooperate with scientists in the water industry to try to get the device on the market.
The young scientist has also developed an app called Kindly that uses artificial intelligence to help prevent cyberbullying (网络欺凌). It allows teens to type in a word or phrase to find out if the words they're using are hurtful and amount to (等于) bullying, and thus should be avoided.
In an interview with Time, Rao said that her pursuits(追求)in science started early as a way to improve conditions in society. In a world where science is increasingly questioned or challenged, Rao insists that its pursuit is an important act of kindness. It is the best way that a younger generation can better the world. Science and technology are being employed as never before to handle various issues, such as global warming, the outbreak of disease and so on, she noted.
“We have science in everything we're involved in, and I think that's the biggest thing to put out there, that science is cool, invention is cool, and anybody can be an inventor，” Rao said.“Anybody can do science.”
1．What is one of the reasons for Rao being honored by Time
A．The up to date ideas she had come up with.
B．The large amounts of time she had devoted.
C．The influence she has on young generations.
D．The optimistic attitude she holds to the future.
2．Rao's inventions mentioned in the passage can be described as ________．
A．functional B．environment friendly
C．efficient D．money saving
3．What contributes to Rao's enthusiasm for science
A．Her tolerance for problems.
B．Her amazing brain power.
C．Her exposure to challenges.
D．Her concern about society.
4．What can be a suitable title for the passage
A．High School Student Struggling for Big Dream
B．Young Scientist Named TIME's Kid of the Year
C．Scientific Achievements Applied to Our Real Life
D．Advanced Inventions Used in Bettering the World
B
Do you want to live another 100 years or more Some experts say that scientific advances will one day enable humans to last tens of years beyond what is now seen as the natural limit of the human life span.
“I think we are knocking at the door of immortality (永生)，” said Michael Zey, a Montclair State University business professor and author of two books on the future. “I think by 2075 we will see it and that's a conservative estimate (保守的估计).”
At the conference in San Francisco, Donald Louria, a professor at New Jersey Medical School in Newark said advances in using genes as well as nanotechnology (纳米技术) make it likely that humans will live in the future beyond what was possible in the past. “There is a great effort so that people can live from 120 to 180 years，” he said. “Some have suggested that there is no limit and that people could live to 200 or 300 or 500 years.”
However, many scientists who specialize in aging are doubtful about it and say the human body is just not designed to last past about 120 years. Even with healthier lifestyles and less disease, they say failure of the brain and organs will finally lead all humans to death.
Scientists also differ on what kind of life the super aged might live. “It remains to be seen if you pass 120, you know; could you be healthy enough to have good quality of life？” said Leonard Poon, director of the University of Georgia Gerontology Centre. “At present people who could get to that point are not in good health at all.”
5．What does Michael Zey mean by saying “we are knocking at the door of immortality”？
A．They have got some ideas about living forever.
B．They believe that there is no limit of living.
C．They are able to make people live past the present life span.
D．They are sure to find the truth about long living.
6．What is Donald Louria's attitude towards long living
A．The human body is designed to last past about 120 years.
B．It is possible for humans to live longer in the future.
C．It is still doubtful how long humans can live.
D．People can live from 120 to 180.
7．What does the underlined word“it” in paragraph 4 refers to
A．A great effort.
B．The conservative estimate.
C．The idea of living from 200 to 300 years.
D．The idea of living beyond the present life span.
8．What would be the best title for this text
A．No Limit for Human Life
B．Living Longer or Not
C．Science，Technology and Long Living
D．Healthy Lifestyle and Long Living

Ⅰ.阅读理解
A
【解题导语】　本文是一篇新闻报道，讲述的是来自科罗拉多州的年仅15岁的高中生拉奥，以科学家和发明家的身份被美国《时代周刊》评为第一个年度儿童。
1.C　解析：细节理解题。由第二段中的“Time said in a statement that Rao stood out for her ability to apply scientific ideas to real world problems and her efforts to motivate other kids to take up their own causes.(《时代》杂志在一份声明中表示，拉奥之所以出类拔萃，是因为她能够将科学理念应用于现实世界中的问题，并努力激励其他孩子投身他们的事业)”可知，拉奥被《时代周刊》授予荣誉是因为她对年轻一代的鼓励和影响。故选C。
2.A　解析：推理判断题。由第三段第二句“Rao won praise in 2017 after she developed a portable device to detect lead in water.(在拉奥开发了一种便携式设备检测水里面的铅之后，她在2017年赢得了好评)”和第四段第一句“The young scientist has also developed an app called Kindly that uses artificial intelligence to help prevent cyberbullying.(这位年轻的科学家还开发了一款名为Kindly的应用程序，使用人工智能帮助防止网络欺凌)”可知，拉奥所研究的发明都是比较具有功能性的发明。故选A。
3.D　解析：细节理解题。由第五段第一句“In an interview with Time, Rao said that her pursuits in science started early as a way to improve conditions in society.(拉奥在一次《时代周刊》的采访中说，她最早的科学追求是改善社会条件)”可知，拉奥追求科学的热情来源于她对社会的关心。故选D。
4.B　解析：标题归纳题。由第一段“A 15 year old scientist and inventor has been named as Time's first ever Kid of the Year. (一位15岁的科学家和发明家被《时代》杂志评为第一个年度儿童)”可知，这篇文章的题目应该是“年轻科学家被《时代》杂志评为“年度儿童”。故选B。
【解题导语】　本文是一篇议论文。人类是否能够活得更长更健康？科学家对此有不同的看法。
5.A　解析：推理判断题。根据文章第二段中，“我认为我们正在敲永生的门，” 蒙特克莱尔州立大学的商业教授迈克尔说， “我认为，到2075年我们将会看到这种现象，这是一个保守的估计。”这里教授表明到2075年就可以实现永生，由此判断出这里的含义是科学家们对如何获得永生有了一些想法。故选A。
6.B　解析：细节理解题。根据第三段“At the conference in San Francisco, Donald Louria, a professor at New Jersey Medical School in Newark said advances in using genes as well as nanotechnology make it likely that humans will live in the future beyond what was possible in the past.”唐纳德教授说使用基因以及纳米技术的进步表明人类将生活在超越过去可能的未来是很可能的。所以这里教授觉得人类在未来会活的更久是有可能的。故选B。
7.D　解析：代词指代题。根据第三段末尾和第四段第一句可知，有些科学家表明，人类可以活到200年，300年或者500年，是没有限制的，但是许多专攻衰老方面的科学家对此抱有疑问，认为人体的设计不适合活过大约120年。所以这里it指超越现有年龄范围的观点。故选D。
8.B　解析：标题归纳题。文章第二段中的“I think we are knocking at the door of immortality” 教授迈克尔表明到2075年就可以实现永生，第四段中的“However, many scientists who specialize in aging are doubtful about it and say the human body is just not designed to last past about 120 years.” 然而，许多专门研究衰老问题的科学家对此表示怀疑，他们说，人体的设计不适合活过大约120年，提出人类永生的质疑，所以整篇文章是围绕着人类是否永生展开。故短文的最佳标题为“人类是否能够活得更长更健康”。故选B。
