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 (核聚變). 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.

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】
這是一篇說明文。文章主要介紹了四位來自不同領(lǐng)域的青少年科學(xué)家的情況，以及分別介紹了他們的發(fā)明。
【1題詳解】
細節(jié)理解題。根據(jù)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發(fā)明了一種癌癥生物傳感器，他說這種傳感器比現(xiàn)在的技術(shù)快168倍，便宜26667倍，靈敏度高400倍。由此可知，Jack Andraka設(shè)計了醫(yī)療器械。故選C。
【2題詳解】
細節(jié)理解題。根據(jù)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，他的靈感來自于The Radioactive Boy Scout，這本小說講述了一個孩子試圖建造一個核反應(yīng)堆但失敗了的故事。由此可知，是一本故事書激發(fā)了Taylor Wilson對發(fā)明的興趣。故選D。
【3題詳解】
推理判斷題。根據(jù)最后一段中“His solution only produces water and small amounts of carbon dioxide.”可知，他的解決方案只產(chǎn)生水和少量的二氧化碳。由此可推知，Daniel Burd的發(fā)明很環(huán)保。故選B。
【4題詳解】
細節(jié)理解題。根據(jù)Taylor Wilson部分中“He received a Thiel Fellowship, which gave him $100,000 to work on his own research.(他獲得了蒂爾獎學(xué)金，獲得了10萬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. (她在英特爾科學(xué)人才搜索中獲得了10萬美元的最高獎項)”可知，四位科學(xué)家中，Taylor Wilson和Sara Volz兩人獲得了同樣數(shù)目的錢來繼續(xù)自己的研究，故C選項“他們中的兩個人贏得了同樣數(shù)目的錢來繼續(xù)他們的研究”正確。故選C。
【5題詳解】
推理判斷題。根據(jù)第一段“We’ve got a list of teen scientists from a variety of fields.”可知，我們有一份來自不同領(lǐng)域
青少年科學(xué)家的名單。以及文章主要介紹了四位來自不同領(lǐng)域的青少年科學(xué)家的情況，以及分別介紹了他們的發(fā)明。結(jié)合選項可推知，文章最有可能選自一本雜志。故選B。
