Scientists found that sleeping considerably improves our creativity. After taking a nap people are able to think faster and put more imagination into their thinking. Besides, if we dream, the thinking abilities are improved even more.

Researchers consider that sleeping on a problem in most cases leads to elucidation(解释). They say when a person enters a phase called Rapid Eye Movement (REM) during sleep, it increases the effect. Such phase takes place right before we awake and according to scientists it helps our brain make links between unrelated subjects.

In the study, led by Professor Sara Mednick, scientists made a conclusion that the REM was “important for assimilating(消化) new information into past experience” in order to find solutions to creative problems.

Prof. Mednick is a psychiatrist at the University of California. Her study involved the analysis of 77 adults. Each participant was given several word-associated creative tasks. All tasks were given in the morning, with participants being shown a number of groups of 3 words, for example: cookie, heart and sixteen. They were asked to come up with a word that would be associated with all three given terms—like sweet. Sometime later, after some participants were allowed to sleep, they were asked to perform the same tasks and some new ones. It is worth mentioning that while some people slept, researchers used brain scans to see the type of sleep each participant entered.

When given the same tasks, participants, who took a nap, were able to give more varied solutions, some of which were much better than they gave earlier. But when given new tasks, researchers found that those who entered REM sleep had a 40 percent better result compared to the performance they showed in the morning.

1.What does “it” refer to in the second paragraph?

A. The effect.            B. REM.            C. Sleep.            D. A problem.

2.Why do the researchers study the REM?

A. Because REM takes place just after you sleep.

B. Because REM can store more information.

C. Because REM can help find creative solutions

D. Because REM can make a creative invention.

3.What can we know from this passage?

A. Taking a short nap is good for your thinking during the day.

B. Sleeping has three processes which is good for creativity.

C. Each adult was allowed to sleep after the task was given.

D. REM is a process taking place right after we awake when we nap.

4.The important stage in the study is________.

A. to think of a creative word

B. to show a group of 3 words

C. to give participants time to think

D. to let some participants sleep for a while

Researchers have found that learning two languages can greatly improve our mental development. For example, researches show us that bilingual experience helps us to rapidly make sense of information.

When given a task where children have to focus on one thing and ignore distracting information, bilingual children have shown themselves to the task. When they are asked to change their focus elsewhere, bilingual children also do this more effectively.

Focusing and changing attention are important abilities that go beyond bilingualism: This ability helps us to rapidly learn and progress information and function well in school and other learning environments.

B

Advice to “sleep on it” could be well founded, scientists say. After a good night’s sleep a problem that couldn’t be solved the night before can often appear more manageable, although the evidence（证据）until now has been personal experience. But researchers at the University of Luebek in Germany have designed an experiment that shows a good night’s sleep can improve insight（洞察力）and problem-solving.

“If you have some newly-got memories in your brain, sleep acts on these memories and rebuild them, so that after sleep the insight into problem which you could not solve before increases,” said Dr Jan Born, a neuroscientist（神经病学专家）at the university. To test the theory, they taught volunteers two simple rules to help them turn some numbers into a new order．There was also a third，hidden rule，which could help them increase their speed in solving the problem．The researchers divided the volunteers into two groups：half were allowed to sleep after the training while the rest were forced to stay awake．Dr Jan Born and his team noticed that the group that had slept after the training were twice as likely to figure out the third rule as the other group．“Sleep helped，”Born said in a telephone interview．“The important thing is that you have to have a memory representation in your brain of the problem you want to solve and then you sleep，so it can act on the problem．”But Born admitted that he and his team don’t know how rebuilding of memories occurs or what governs it．Pierre Maquet and Perrine Ruby of the University of Liege in Belgium said the experimental evidence supports the suggestions that sleep can help develop creative thinking．Although the role of sleep in human creativity will still be a mystery，the research gives people good reason to fully respect their periods of sleep，they added．

60．The underlined phrase“sleep on it”in Paragraph 1 probably means_________．

A．to delay deciding something until the next day

B．to get as much sleep as possible

C．to go on sleeping without being disturbed

D．to sleep till after the time you usually get up in the morning

61．Jan Born and his team carried out the experiment through________．

A．comparison    B．interview        C．survey          D．imagination

62．It can be inferred from the passage that___________．

A．people should sleep so long as they have time

B．sleep is the only way to solve hard problems

C．people have various periods of sleep   D．people know how sleep rebuilds memories

63．What would be the best title for the passage?

A．How Sleep Works．               B．Sleep Helps Solve Problems．

C．No Evidence，But Well Founded．   D．Born’s Discovery on Sleep．

Though technology has considerable wonderful benefits, it is becoming increasingly obvious that our addiction to technology and overall cell phone addiction is becoming too common. However powerful it is, it does have a power-off button.1.

● Powering-down prevents the fear of missing out.

Scientifically speaking, the Fear of Missing Out (FOMO) has been recognized as a recently rising psychological　 disorder brought on by the huge increase in technology addiction. The premise(假定) is simple.2.Within　 this constant stream of information, our fear of being left out continues to grow. Turning off social media and learning how to live in the moment are both important skills in this modern world.

● Powering-down promotes creation over consumption.

Essentially, most of our time is spent in one of the two categories: consuming or creating. Certainly, technology can contribute to creating. For example, this article was written (created) on a computer. But most of the time we spend in front of technology is spent consuming (playing video games, browsing the Internet, watching movies, listening to music).3. It needs more creating. It needs your passion, your solution, and your unique contribution.

Power down and begin contributing to a better world because of it.

●4.

If we power down for a while, we can learn something about ourselves. We will learn we are far more addicted to technology than we would have guessed. But that is the nature of addiction, isn’t it? We can never fully realize our level of addiction until the item is out of sight. The only way to truly discover technology’s controlling influence on our life is to turn it off, walk away, and sense how strong the pull is to turn it back on.

● Life, at its best, is happening right in front of you.

Our world may be changing, but the true nature of life is not. Life, at its best, is happening right in front of you.5.The conversations are natural and authentic. And the love is real. But if we are too busy staring down at our screen, we’re going to miss all of it.

A.It has a negative effect on our creativity.

B.Our world doesn’t need more consuming.

C.The experiences in life will never repeat themselves.

D.The following are some important reasons to unplug.

E.Our social media are filled with everything happening all around us.

F.Powering-down helps remove unhealthy feelings of envy and loneliness.

G.Technology addiction can only be understood when the object is taken away.

Move Earth – it’s no science fiction

LONDON – Scientists have found an unusual way to prevent our planet from overheating: move it to a cooler spot. All you have to do is send a few comets (彗星) in the direction of Earth, and its orbit will be changed. Our world will then be sent spinning into a safer, colder part of the solar system.

This idea for improving our climate comes from a group of US National Aeronautics and Space Administration（NASA）engineers and American astronomers. They say their plan could add another six billion years to the useful lifetime of our planet—effectively doubling its working life.

The plan put forward by Dr Laughlin, and his colleagues Don Korycansky and Fred Adams ,needs carefully directing a comet or asteroid so that it passes close by our planet and sends some of its gravitational energy to Earth.

“Earth’s orbital speed would increase as a result and we would move to a higher orbit away from the Sun,” Laughlin said.

Engineers would then direct their comet so that it passed close to Jupiter or Saturn. The comet would pick up energy from one of these giant planets. Later its orbit would bring it back to Earth, and the process would be repeated. In the short term, the plan provides an ideal way to global warming, although the team was actually concerned with a much greater danger. The sun is certain to heat up in about a billion years and so “seriously compromise” our biosphere（生物圈）— by cooking us.

That’s why the group decided to try to save Earth.

The plan has one or two worrying aspects, however. For a start, space engineers would have to be very careful about how they directed their asteroid or comet towards Earth. The smallest miscalculation（误算）in orbit could fire it straight at Earth—with deadly consequences.

There is also the question of the Moon. As the current issue of Scientific American magazine points out, if Earth was pushed out of its current position it is “most likely the Moon would be stripped away from Earth,” it states. This would greatly change our planet’s climate.

1.What makes the scientists plan to move Earth?

A．A few comets are moving to the direction of Earth.

B．Earth’s working life is coming to an end soon.

C．Earth will become too hot for mankind to keep alive.

D．The moon is moving farther and farther away from Earth.

2.If the plan is successful, Earth will have a working life of ______years.

A．12 billion            B．6 billion              C．18 billion            D．24 billion

3.What serious problems might the plan cause according to the passage?

A．The comet might hit Earth and man might lose the moon.

B．Earth might be moved too far away and man might be frozen to death.

C．The comet might hit Jupiter or Saturn and never return to Earth.

D．Earth’s working life might be greatly shortened.

4.What does the underlined word “compromise” mean?

A．provide               B．benefit               C．share                   D．endanger

Scientists said they have found evidence of a giant planet far out in our solar system. In a statement, the California Institute of Technology(Caltech) said this planet travels a strange “highly elongated orbit in the distant solar system”.

The discovery was made by two researchers at Caltech; Konstantin Batygin and Mike Brown. They used mathematical modeling and computer simulations (模拟)to find the planet. So far, there have not been any direct observations of the planet. “My jaw hit the floor,” said astronomer Mike Brown, the moment he realized there might be a ninth planet.

The scientists said it would take this planet 10,000to 20,000 years just to make one full orbit around the sun. The new planet, called “Planet Nine” has a mass about 10 times the size of Earth.

It is believed that the planet orbits, or travels, around the sun from a great distance. The planet Neptune’s average distance to the sun is about 4.5 billion kilometers. But “Planet Nine” could be 20 times farther away from the sun than that. While they did not get a picture of “Planet Nine” yet, the scientists say they are using the biggest and best telescopes on Earth to try to find it.

Brown and Batygin reported their finding in The Astronomical Journal. They say that this new planet is so large that there should be no doubt that it is a true planet, once they confirm it.

Robert Massey is with the Royal Astronomical Society in London. He told AFP that planets have been predicted before, and then were not found. But, he said the work of the these researchers is definitely worth following up. “It would be a really exciting thing to find. At the moment it’s simply a prediction.”

1.How was the evidence of the ninth planet found?

A. Through a special telescope

B. Through researchers’ direct observation

C. Through studying its special orbit in the solar system

D. Through mathematical modeling and computer simulations

2.What can we know about “Planet Nine” from the text?

A. It is much smaller than the earth

B. It travels a normal orbit like other planets

C. Its distance to the sun is about 90 billion kilometers

D. Its picture has been caught by the biggest and best telescope

3.What’s Robert’s attitude towards the discovery of “Planet Nine”?

A. Worried　　 B. Supportive

C. Indifferent　　 D. Opposed

4.What’s the best title for the text?

A. The discovery of the largest planet

B. A big prediction of the solar system

C. A ninth planet may be in the solar system

D. The ninth planet has been found in the solar system
