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 （生物传感器） 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 （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 （塑料） 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．

2. What excited Taylor Wilson's interest in his invention？ ______

A. A novel by a kid．B. Plastic pollution．

C. Energy shortage．D. A story book．

3. What do we know about Daniel Burd's invention？ ______

A. It won him a ﹩100，000 prize．

B. It is environmental friendly．

C. It was completed in three months．

D. It is widely used in everyday waste．

Are you getting enough protein (蛋白质)? The question provides its own answer: If you are worrying about

the amount of protein in your diet, then you are almost certainly eating more than enough.

You merely need to visit a western supermarket today to see that many people regard protein as some kind of

excellent medicine—one food companies are profitably adding to anything they can. "When the Box says 'Protein',

Shoppers say 'I'll take it'" was the headline of a 2013 article in The Wall Street Journal.

The intensity of our protein obsession can only be understood as part of a wider series of diet battles that go

back half a century. If we now thirst for protein as if it were water, it may be because the other two macronutrients

—fats and carbohydrates—have each in turn been made to seem poisonous (有毒的) in the public mind.

In the current nutrition wars, protein has emerged as the last macronutrient left standing. David L. Katz, an

American doctor and public health scholar who is the director of the Yale-Griffin Prevention Research Center said,

"First they told us to cut fat. But instead of whole grains and lentils, we ate low-fat junk food." Then food marketers

heard the message about cutting carbohydrates and sold us protein-enriched junk foods instead.

For decades now, there has been a tendency to think about what we eat and drink in terms of nutrients, rather

than read whole ingredients in all their complexity. A combination of diet fads and clever marketing has got us

here. It doesn't matter whether we fixate on "low fat" or "low carbohydrates" or "high protein" —we are making the

same old mistakes about nutrition in a new form.

4. How does the author begin the article?

A. By raising a question.

B. By giving an assumption.

C. By describing a phenomenon.

D. By illustrating a typical case.

5. How many kinds of macronutrients does food provide us with according to paragraph 3?

A. Two. B. Three. C. Four. D. Five.

6. What is the author's attitude towards protein according to the text?

A. Cold. B. Crazy. C. Sensible. D. Critical.

Imagine a cat that does not need someone to clean up after it keeps an older people company and helps them

remember to take their medicine ． That is the shared dream of the toy maker Hasbro and scientists at Brown

University in Providence ， Rhode Island ． The researchers received a ﹩3-million-dollar from the National

Science Foundation for a special project ． They want to find ways to add artificial intelligence ， or AI ， to

Hasbro's "Joy for All" robotic cat．

The cat has already been for sale for two years． Though priced at over 1，000 dollars， it sold quite well．

It was meant to act as a "companion" （陪伴） for older people ． Now the project is aimed at developing

additional abilities for the cat ． Researchers are working to decide which activities older adults may need the

most． They hope to make the cat perform a small number of activities very well ． Such activities include finding

lost objects and reminding the older people to take medicine or visit their doctor ． They also want to keep the cost

down to just a few hundred dollars．

It is an idea that has appealed （有吸引力） to Jeanne Elliott． Her 93-year-old mother Mary Derr lives with

her in South Kingstown ． Derr has dementia （痴呆）． The Joy for All cat that Elliot bought this year has

become a true companion for Derr． The cat stays with Derr and keeps her relaxed while Elliott is at work． Elliot

said a robotic cat that helps her mother to remember to take her medicine and be careful when she walks would be

greater．

The researchers are trying to learn how the improved cats will complete helpful activities and how they will

communicate． They say that they do not want a talking cat ， however． Instead they are trying to design a cat

that can move its head in a special way to successfully communicate its message． In the end， they hope to create

an exchange between the human and the cat in which the human feels the cat needs them ． By doing so， the

researchers hope they can even help prevent feelings of loneliness and sadness among elderly people．

7. What's the purpose of the project？ ______

A. To reduce the pain of the elderly．

B. To increase the sales of a medicine．

C. To help make the robotic cat smarter．

D. To invent a robotic cat for the elderly．
