Ⅰ.阅读理解
Robert Jarvik, born on May 11, 1946 in Michigan and raised in Stamford, is a medical scientist and researcher, who played an important role in the invention of the artificial heart.He was interested in medicine from a young age.He watched his father perform operations and gained a patent for a machine applied in the medical operation before he graduated from high school.
Jarvik attended Syracuse University and considered a career in art.When his father developed heart disease suddenly, he decided then to work on a medical career.He applied to medical schools, but was not admitted to any schools in the US.Before long, he was admitted to the medical school in Italy and stayed there for two years.He returned to get a degree in medicine from New York University in 1971.
After working for a period of time; Jarvik got a job in the organ transplant (器官移植) program at the University of Utah in 1972.He worked with the director of the program, Willem Kolff, who invented the kidney dialysis (肾透析) machine.
By the time Jarvik came to the University of Utah, the organ program had already developed the primary artificial heart.He improved it by creating a diaphragm (横膈膜), which solved many issues with the heart.Eventually, he created the first artificial heart in 1981, the Jarvik-7, to be placed in a human patient, which was considered one of the most important inventions in human history.
Barney Clark, a retired dentist suffering from serious heart disease, received the Jarvik-7 transplant on December 2,1982.He lived for 112 days after the operation, but the transplant was considered a success.Though receiving criticism for the risk referred to transplant an artificial heart, the Jarvik-7 still became very important for patients who were waiting for a heart.In 1987, Jarvik moved to New York City and formed Jarvik Research Inc.He began developing a new heart — the Jarvik 2,000.This smaller machine fits inside a patient's heart rather than replacing the entire organ.

Ⅰ.阅读理解
When I was younger, I thought science would make good things for everybody. It was obviously useful; it was good. But then during the war I worked on the atomic bomb. This result of science was obviously very serious — it represented the destruction of people and put our future at risk. I had to ask myself, “Is some evil involved in science？” I thought long and hard about this question, and I will try to answer it in this talk.
The first way in which science is of value is familiar to everyone: scientific knowledge is an enabling power to do either good or bad — but it does not carry instructions on how to apply it. Such power has obvious value — even though the power may be denied by what one does with it.
Another value of science is the intellectual enjoyment it can provide us with. When we look at any question deeply enough, we feel the excitement mystery coming into us again and again. With more knowledge comes a deeper, more wonderful mystery, inspiring one to look deeper still. Never concerned that the answer may let us down, with pleasure and confidence we turn over each new stone to find unimagined strangeness, just like opening a box of chocolate.
I would now like to turn to a third value that science has. The scientist has a lot of experience with ignorance and doubt and uncertainty, and this experience is of great importance. When a scientist doesn't know the answer to a problem, he is ignorant. When he has an idea as to what the result is, he is uncertain. And when he is pretty sure of what the result is going to be, he is still in some doubt.
Our freedom to doubt was born out of deep and strong struggle against authority in the early days of science. In order to progress, we must not forget the importance of this struggle; we must recognize our ignorance and leave room for doubt. Permit us to question — to doubt — to not be sure.
语篇解读：本文是一篇议论文。文章主要讨论了科学的价值以及科学中一直存在的怀疑精神。
1．What is the purpose of the first paragraph
A．To blame science.
B．To introduce the topic.
C．To doubt the value of science.
D．To emphasize the serious situation.
解析：选B 推理判断题。根据第一段最后两句可知，作者以提问的方式引出科学中是否有邪恶这一话题，并且最后一句话引出下文中可能讲到的内容，所以第一段的目的是引出主题。故选B。
2．What can we infer from the passage
A．The author made an atomic bomb accidentally.
B．Scientists are short of knowledge and certainty.
C．Science is valueless if falling into the wrong hands.
D．Science generates wonderful questions and mysteries.
解析：选D 推理判断题。根据第三段第二句可知，科学可以让我们深入地看待问题，进而让我们感受到神秘，这都是科学带给我们的美好的感觉，因此D项“科学产生了奇妙的问题和谜团。”符合题意。故选D。
3．What does the last paragraph mainly talk about
A．Scientists are scared to question the authority.
B．Struggle is not necessary in the science research.
C．Challenging the authority always exists in science.
D．Sureness is an important factor to scientists' success.
解析：选C 段落大意题。最后一段主要讲述挑战权威在科学的早期就存在，而现在怀疑的自由也是源于早期对权威的挑战。C项“挑战权威在科学中总是存在的。”是对最后一段的总结。故选C。
4．What can be a suitable title for the text
A．The Value of Science
B．The Uncertainty of Science
C．The Power of Science
D．The Destruction of Science
解析：选A 标题归纳题。文章第一段引出主题，第二、三、四段主要讲述了科学带来的价值，最后一段主要讲述科学中挑战权威一直存在，由此可以看出，文章主要讲述了科学的价值。A项“科学的价值”总结了文章的主旨，适合作为文章的标题。故选A项。

The rain was sudden and heavy on a cold night over ten years ago.Moving all the way against the heavy rain, my bus could barely stick to its normal route and was forced to stop at the station due to flash flooding.
With still two kilometers to go, time ran against me picking up my then four year old daughter from her childcare center.What waited for me was knee high water.I had no choice but to struggle through in the pouring rain to buy a cheap plastic coat in the shopping mall for my daughter.
After taking off my jacket and putting it into my bag to keep dry, I pulled up my skirt and took off my shoes, starting to run.Although I was wet through when arriving at the daycare center, I felt lucky to be only a few minutes late.Now I had to fix another problem.
All means of getting home appeared impossible to me.There were no buses with the clock striking 6 pm.I had no money to pay for a taxi.As the sky turned darker and darker, it seemed that we could never manage to get home.
The only thing we could do was to stand outside the childcare center staring at the rain pouring down.There was no sign of stopping.Lost in my own thoughts, I just hardly noticed another parent pull up and race inside to collect his child ten minutes later.I did not recognize him and my thoughts turned back to my current situation.

Big Problems, Simple Solutions
Inventions are improving health and well-being in communities around the world.Speakers at recent TED events have shared simple and inexpensive solutions that can solve everyday problems.
FUEL BRIQUETTES (燃料砖)
In the developing world, smoke from indoor cooking kills more than 2 million children each year.In fact, it's the number one cause of death of children under five.Amy Smith, founder of D-Lab at the Massachusetts Institute of Technology (MIT), discovered a way to make a safe cooking fuel.The material she uses is also free and plentiful: farm waste.
Smith invented a low-cost device that turns farm waste into fuel briquettes.These briquettes produce smoke that is less dangerous than the smoke from other fuel.They also burn hotter and last longer.Farmers can make these briquettes from readily available waste.This invention has an economic benefit, too.Farmers can buy the device for $2 and sell briquettes they don't use.Smith estimates (估算) that this can increase a farmer's income by $500 a month.
DISASTER SHELTERS
Over 31 million people worldwide lose their homes every year due to natural disasters such as hurricanes and earthquakes.After these disasters, many people live in terrible conditions — in tents or in large stadiums with no privacy.Graphic designer Michael McDaniel invented inexpensive and temporary housing for people in these situations.
Called the Reaction Ex, these shelters are small, one-room houses that comfortably hold up to four people.They're made from a plastic that is strong, recyclable, and super light.In fact, they're so light that they can be lifted by hand and are very portable as well.McDaniel hopes that his invention will provide an affordable solution to help people rebuild their lives after a natural disaster.

Louis Braille was born in France in 1809.Sadly when he was a little boy, he had an accident.By the time he was four years old, he was completely blind.However, at the age of ten, Louis was lucky enough to go to one of the first schools for blind children in Paris.At this particular school they had special books.They were written in ordinary French but the letters raised up off the page, so that the students could feel the shape of the words and read them.But there were two problems with this system.First, the letters were huge and difficult to read.Second, the books were very expensive so the school library only had fourteen altogether.Louis, who was very clever and creative, thought of a better way to improve books for blind people to read.
In 1821, when Louis was twelve years old, a soldier came to his school.This man had invented a system for soldiers to send and receive messages in the dark.Although this idea had not worked very well, Louis became very excited and began experiments with it.By the time he was fifteen, he had invented a system which used only six dots.And by 1827 the first book using his system was published.
It still took a long time before people realized what a wonderful invention Braille's system was.In fact, Louis died in 1852 and did not live to see the success of his system, which has been adapted to almost every language in the world.Thanks to him, blind or weak-sighted people are able to read or write as well as any sighted person.

Big Problems, Simple Solutions
Inventions are improving health and well-being in communities around the world.Speakers at recent TED events have shared simple and inexpensive solutions that can solve everyday problems.
FUEL BRIQUETTES (燃料砖)
In the developing world, smoke from indoor cooking kills more than 2 million children each year.In fact, it's the number one cause of death of children under five.Amy Smith, founder of D-Lab at the Massachusetts Institute of Technology (MIT), discovered a way to make a safe cooking fuel.The material she uses is also free and plentiful: farm waste.
Smith invented a low-cost device that turns farm waste into fuel briquettes.These briquettes produce smoke that is less dangerous than the smoke from other fuel.They also burn hotter and last longer.Farmers can make these briquettes from readily available waste.This invention has an economic benefit, too.Farmers can buy the device for $2 and sell briquettes they don't use.Smith estimates (估算) that this can increase a farmer's income by $500 a month.
