Amazing Scientists

Who Happen to Be Teenagers

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 algae(藻类)based on their oil output for the purpose of growing them as biofuel. 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 lntel 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(细菌)responsible for decomposing the plastics.

His solution only produces water and small amounts of carbon dioxide.He says it could easily be used elsewhere.

【解析】

这是一篇说明文。文章介绍了几位令人惊讶的科学家以及他们的发明。

1.细节理解题。根据Jack Andraka中的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.“杰克•安德拉卡(Jack Andraka)发明了一种用于癌症的生物传感器，他表示，这种传感器的速度比现在的技术快168倍，价格便宜26667倍，灵敏度高400倍。”可知，Jack Andraka设计了医疗器械。故选C。

2.细节理解题。根据Taylor Wilson中He was inspired by The Radioactive Boy Scout, a novel in which a kid tries and fails to build a nuclear reactor.“他的灵感来自《放射性童子军》(The Radioactive Boy Scout)，这是一本讲述一个孩子试图建造核反应堆却失败的小说。”可知，一本故事书激发了泰勒·威尔逊对他的发明的兴趣。故选D。

3.推理判断题。根据Daniel Burd中His solution only produces water and small amounts of carbon dioxide.He says it could easily be used elsewhere.“他的解决方案只产生水和少量的二氧化碳。他说，它可以很容易地用于其他地方。”由此判断出，Daniel Burd的发明对环境几乎没有危害。故选B。
