A
We’ve got a list of teen scientists from a variety of fields.
Jack Andraka
Jack Andraka created a biosensor for cancer that he says is 168 times faster, 26, 667 times less expensive and 400 times more sensitive than technology nowadays.
He’s the youngest person to have spoken in front of the Royal Society of Medicine.
Taylor Wilson
Taylor Wilson was the youngest person to achieve nuclear fusion (核聚变). He was inspired by The Radioactive Boy Scout, a novel in which a kid tries and fails to build a nuclear reactor.
Taylor thought he could do better. Long story short, he wanted to build a small nuclear reactor. And he did it at the age of fourteen. He received a Thiel Fellowship, which gave him $100,000 to work on his own research.
Sara Volz
Sara Volz performed experiments in which she grew algaebased on their oil output for the purpose of growing them as biofuel (生物燃料). This research is especially important as the world continues to search for a way to lessen our dependence on non-renewable energy. She won the top prize of $100,000 in the Intel Science Talent Search.
Daniel Burd
Plastic usually takes thousands of years to decompose (降解), but this high school student Daniel Burd managed to do it in three months.
In an experiment, he mixed plastic bags and a special kind of dirt together, and found that they did decompose faster. He then performed tests to find the bacteria responsible for decomposing the plastics.
His solution only produces water and small amounts of carbon dioxide. He says it could easily be used elsewhere.

3. What do we know about Daniel Burd’s invention?
A. It won him a $100,000 prize. B. It is environmentally friendly.
C. It was completed in three months. D. It is widely used in everyday waste.
4. Which of the following statement is true?
A. Sara Volz is the youngest person to spoken in front of the Royal of Medicine.
B. Plastic often takes hundreds of years to decompose.
C. Two of them have won the same amount of money to continue their research.
D. Daniel Burd’s solution will be hard to be used in our daily life.
5. Where is the text probably taken from?
A. A guidebook. B. A magazine.
C. An advertisement. D. A dictionary.
【答案】1. C 2. D 3. B 4. C 5. B
【解析】
这是一篇说明文。文章主要介绍了四位来自不同领域的青少年科学家的情况，以及分别介绍了他们的发明。
【1题详解】
细节理解题。根据第二段“Jack Andraka created a biosensor for cancer that he says is 168 times faster, 26,667 times less expensive and 400 times more sensitive than technology nowadays.”可知，Jack Andraka发明了一种癌症生物传感器，他说这种传感器比现在的技术快168倍，便宜26667倍，灵敏度高400倍。由此可知，Jack Andraka设计了医疗器械。故选C。
【2题详解】
细节理解题。根据Taylor Wilson部分中“He was inspired by The Radioactive Boy Scout, a novel in which a kid tries and fails to build a nuclear reactor.”可知，他的灵感来自于The Radioactive Boy Scout，这本小说讲述了一个孩子试图建造一个核反应堆但失败了的故事。由此可知，是一本故事书激发了Taylor Wilson对发明的兴趣。故选D。
【3题详解】
推理判断题。根据最后一段中“His solution only produces water and small amounts of carbon dioxide.”可知，他的解决方案只产生水和少量的二氧化碳。由此可推知，Daniel Burd的发明很环保。故选B。
【4题详解】
细节理解题。根据Taylor Wilson部分中“He received a Thiel Fellowship, which gave him $100,000 to work on his own research.(他获得了蒂尔奖学金，获得了10万美元用于自己的研究)”以及Sara Volz部分中“She won the top prize of $100,000 in the Intel Science Talent Search. (她在英特尔科学人才搜索中获得了10万美元的最高奖项)”可知，四位科学家中，Taylor Wilson和Sara Volz两人获得了同样数目的钱来继续自己的研究，故C选项“他们中的两个人赢得了同样数目的钱来继续他们的研究”正确。故选C。
【5题详解】
推理判断题。根据第一段“We’ve got a list of teen scientists from a variety of fields.”可知，我们有一份来自不同领域
青少年科学家的名单。以及文章主要介绍了四位来自不同领域的青少年科学家的情况，以及分别介绍了他们的发明。结合选项可推知，文章最有可能选自一本杂志。故选B。
