Astronauts in the space stations for long missions often work very long days. Tasks are scheduled(安排) so tightly that break times are often used to finish the day’s work. It’s especially hard for long missions on the International Space Station (ISS). ISS crew members usually live in space for at least a quarter of a year. They work five days on and two days off to mimic the normal way they do things on Earth as much as possible. Weekends give the crew valuable time to rest and do a few hours of housework. They can communicate with family and friends by email, Internet phone and through private video meetings.

While astronauts cannot go to a baseball game or a movie in space, there are many familiar activities that they can still enjoy. Before a mission, the family and friends of each ISS crew member put together a collection of family photos, messages, videos and reading materials for the astronauts to look at when they will be floating 370 kilometers above the Earth. During their mission, the crew also receives care packages with CDs, books, magazines, photos and letters. Today, the Internet can be used on the ISS, giving astronauts the chance to do some “web surfing” in their personal time. Besides relaxing with these more common entertainments, astronauts can simply enjoy the experience of living in space.

Many astronauts say that one of the most relaxing things to do in space is to look out of the window and stare at the universe and the Earth’s vast land mass and oceans.

1.What does the word “mimic” in Paragraph 1 probably mean?

A. Find　　 B. Copy

C. Change　　 D. Lose

2.In the last paragraph, the author shows that astronauts ____________.

A. get more pleasure in space than on the Earth

B. find living in space a bit boring and tiring

C. regard space life as common

D. love to see the Earth from space

3.The passage mainly discusses how astronauts ____________.

A. work for longer missions in space　　 B. connect with people on the Earth

C. observe the Earth from space　　 D. spend their free time in space

When NASA astronaut Scott Kelly completes his yearlong mission on the International Space Station next year, he’ll come back just a little bit younger than his twin, Mark, than he was before. This is because time travels more slowly in space, a phenomenon first described by Albert Einstein’s 1915 theory of general relativity.

This December, universities and academies around the world are celebrating the 100th anniversary of the theory’s publication.

Even 60 years after his death, Einstein is still the most important scientist of the modern era. Looking back as far as 2,400 years ago, only Newton, Galileo and Aristotle were his equals.

Born in the era of horse-drawn carriages, his ideas started a technological revolution that brought about more change in one century than in the 2,000 years before.

In 1905, Einstein published four important scientific papers. These completely changed people’s ideas about space, time, light and matter. In one of these papers Einstein. introduced his theory of special relativity. Two groundbreaking parts of the theory were about the relationship between mass and energy and the speed of light. Einstein was able to show that mass and energy were connected through the formula E＝MC2. The theory also says that no object can travel faster than the speed of light.

About 10 years later came his theory of general relativity, the theory that modern physics is really based on. In Einstein’s mathematics, space has three dimensions, and the fourth dimension is time. Space and time are part of one continuum, called space-time. The presence of mass changes space-time, which explains where gravity comes from.

Computers, satellites, telecommunication, lasers, television and nuclear power, many of the biggest developments in the modern world, can be linked to Einstein’s work.

“We are a different people than we were a century ago,” said astrophysicist Michael Shara of the American Museum of Natural. History, “completely different, because of Einstein.”

However, there’s more to him beyond the image of a science mastermind. Einstein, as a person, has also become a grandfatherly icon in our culture.

He liked playing Mozart on his Violin and keeping fit by hiking and walking. Power was not his goal. In 1952, the young nation of Israel asked Einstein to be its president, but he refused.

And, yes, he was eccentric. With hair like that, how could he not be?

1.The first paragraph was written to 　　　　　 .

A. get readers to wonder about the effects of space travel on astronauts’ health

B. interest readers in the relationship between time and space

C. describe what gave Einstein the inspiration for his theories

D. lead in to the topic of the theory of general relativity

2.From the article, it can be concluded that 　　　　　 .

A. the theory of general relativity is mainly about space and time

B. the theory of general relativity proves that the speed of light is the fastest of all speeds

C. the theory of general relativity is about math and has nothing to do with physics

D. the most important parts of the theory of special relativity are about space and energy

3.By using Michael Shara’s words, the author intends to 　　　　　 .

A. give high praise to Einstein’s important publications

B. stress the great contribution that Einstein made to the modern world

C. suggest that more research needs to be done into Einstein and his work

D. say that there was more to Einstein than just being a science genius

Who knows about sleep? Astronauts (宇航员). They have to. Their bodies are cut off from the outside world that reminds (提醒) us what time it is. But actually, it's even worse than that. An astronaut reported in his diary that he was likely to make mistakes on days following an unusually late bedtime.

So NASA started doing some serious research. They quickly realized that we're a slave to the outside world. Without light and darkness, we' re unable to regulate (管理) sleep times.

Because of modern technology, we're all living more like astronauts now. Light is no longer a function (功能) of the sun, but of always-on indoor lights, TV and computer screens. Temperature no longer follows a cycle of cooling at night and warming during the day. Is it any wonder that a third of Americans have sleep problems?

Maybe you think this doesn't affect you — or at least not much. You're wrong. Research done on non-astronauts has shown the same thing. After two weeks of six hours of sleep a night; you're drunk. By the end of two weeks, the six-hour sleepers behaved as badly as those who hadn't slept for 24 hours.

But what did they say when asked how they felt? "It's not affecting me." So if you are performing poorly because of sleep problems, you may have no idea. This is a real problem.

So what answers did NASA come up with?

Take an hour to calm down before bed. Yes, you're busy. But your time is not more valuable than an astronaut's.

Keep your bedroom dark, cool and free from noise. Even if you think "the light doesn't affect you" or "the noise isn't that bad", it can still affect sleep quality.

Another advice: forget the alarm clock (闹钟) in the morning; set an alarm to remind you to go to bed at night. When it goes off, finish up any work on the computer, and turn off any unnecessary lights. This prevents you from cheating yourself on sleep and allows you to wake up naturally.

1. What did NASA find about people’s sleep?

A. It takes a long time to develop regular sleep times.

B. It’s strongly influenced by the outside world.

C. It remains untouched by outside influences.

D. It’s hard to change one’s sleep habits.

2.The biggest problem of those who haven’t enough sleep lies in the fact that 　　　　　 .

A. they can’t fall asleep without the lights on

B. they don’t know whether they sleep well

C. they refuse to regulate their sleep times

D. they get too drunk to sleep well

3. What does the underlined sentence in the text mean?

A. You should make full use of your time.

B. You can find the time to get ready to sleep.

C. You can sleep later to finish your work first.

D. You should learn from astronauts’ way of sleep.

4. What’s the advice on the alarm clock?

A. Use it to remind you to sleep.

B. Put it far away from your bed.

C. Get up immediately when it rings.

D. Pay no attention to it when it rings.

Astronauts traveling in space meet forms of radiation that are uncommon on Earth. Some of this radiation has been shown to be harmful to human health. It is linked to cancers and heart problems. Yet a new American study suggests the radiation does not shorten astronauts' lives.

Researchers studied nearly 60 years of health records and other data about male astronauts from the United States. They then compared this data with information about a group of men who are in good health, richer than most Americans and receive good health care-professional athletes. The study found that neither group has higher rates of dying at a young age. In fact, both groups generally live longer than other Americans.

Astronauts are usually well-educated, earn more money and are in better physical condition than the average American. Some earlier research has linked being an astronaut to a lower risk of early death, the researchers noted. The findings were reported in the publication Occupational & Environmental Medicine.

Much of the existing research on mortality rates in astronauts has not yet explored the mental and physical demands of this job. There also has not been a lot of research on whether astronauts show what is known as the "healthy worker effect". This effect leads people with employment of any kind to have fewer medical problems than people who are unable to work, said Robert Reynolds.

Reynolds said, "The challenge has always been to understand if astronauts are as healthy as they would be had they been otherwise comparably employed but had never gone to space at all. To do this, we need to find a group that is comparable on several important factors."

1.How did researchers carry out their study?

A.By doing interviews. B.By analyzing some factors.

C.By comparing different data. D.By doing experiments in the lab.

2.What can we learn from the text?

A.All radiation is harmful to human health.

B.Athletes tend to be poorer than most Americans.

C.Healthy worker effect makes working people healthier.

D.Research has explored the mental and physical demands of being astronauts.

3.What can he inferred from Reynolds' words?

A.They are determined to face the challenge.

B.The research is almost impossible to conduct.

C.Several important factors hold back the research.

D.Astronauts are as healthy even they haven't been Astronaut.

4.What can be a suitable title for the text?

A.Astronauts----Healthy or Otherwise

B.Astronauts Are as Healthy as Athletes

C.Radiation Affects Astronauts' Health

D.Astronauts---- Well-Educated and Earn More

While astronauts in space get to do many exciting things, they miss out on ordinary things that we will take for granted—being able to walk on firm ground, hanging out with family and digging into a slice of hot steaming pizza. Though not much can be done about the first two things, there may soon be a solution to the third one, thanks to this cool 3-D pizza printer.

About a year ago, NASA offered $125,000 to Anjan Contractor, a 3-D technology expert, to build a device that would allow astronauts to make pizza on demand. The mechanical engineer promised that his invention would produce pies in large quantities that looked, tasted and even smelled like pizza made in common ovens.

Late last year, the engineer presented a video of his first prototype(原型) that begins by creating a single slice of dough that is cooked and printed at the same time. Then comes the tomato sauce--a mix of tomato powder, oil and water and finally, a protein slice that resembles cheese. While the video doesn't show the baking process, the inventor says that once the pizza is printed, it can be ready to be consumed in 7 seconds.

While the pie in the video looks delicious enough to attract any pizza lover, Anjan Contractor is far from ready for astronauts. That's because he still has to find a solution to make the food container in the printer last for 30 years. Though that may sound unrealistic ,actually it is not.

Anjan Contractor believes that the only way that is possible is that the water is removed from all the ingredients and then they are reduced to the powder form. This, as you can imagine, will not be so easy. But, while the printer may not be ready for space, it certainly looks ready enough for people on earth. Hopefully, NASA and Contractor will consider selling it to those not fortunate enough to go to Mars !

1.NASA offered $125,000 to Anjan Contractor mainly to ____.

A. create some new type of 3-D printer

B. attract more companies to work for NASA

C. help astronauts in space enjoy fresh pizza one day

D. produce pizza in large quantities to earn great profits

2.The biggest challenge that Anjan Contractor is faced with now is probably that ____

A. he has no money left to go on with his research

B. the pizza doesn't seem appetizing to pizza lovers

C. he has no way to make pizza that can last for thirty years

D. he cannot make the food container last for decades

3.What's the best title of the passage?

A. NASA is trying its best to help astronauts eat better

B. Astronauts may soon be able to enjoy steaming hot pizza

C. NASA is working on making pizza for common people

D. A 3-D pizza printer has been used to make pizza
