According to the report, the picture of the earth in the year 2020 is not a47one. The world will be more48because the population will continue to grow. The population could be499,000 million, almost 3,000 million more than that in 2009. More people would move into cities, especially cities in50countries. Cities in India and Thailand probably would51have a population of 20 million by then.

Researchers have discovered the first Earth-sized planet. It was first marked by scientists' using NASA's Kepler telescope(望远镜), so it's called Kepler﹣186f. It lies about 500 light years from Earth and goes around its star.The planet is the right distance from its star for water: not too close or not too far. Water is one important condition that scientists guess is necessary for life. So it could have water and possible life. It's called a true Earth cousin.

"This planet is an Earth cousin, not an Earth twin," said Barclay, who is among a team of scientists reporting on the discovery in the magazine Science this week.

"It's very exciting to find a planet similar to the Earth，"Barclay said. "It's not easy work because things change as we get more measurements."

Scientists don't know anything about the air of Kepler﹣186f, but it will be a task for future telescopes which can study for chemicals that have something to do with life.

"It's possible for life to live in this planet, but that doesn't mean there is life in it," Barclay said.

So far, scientists have found nearly 1,800 planets in the universe.

"The past year has seen a lot of progress in the search for Earthlike planets. Kepler﹣186f is very important because it is the first planet that is the same temperature and is almost the same size as Earth,"scientist David Charbonneau wrote in an email.

1.Scientists have already found about ________ planets now.

A. 500　　 B. 186　　 C. 1,800　　 D. 1,801

2.Which of the following about Kepler﹣186f is NOT true according to the passage?

A. It could have water and possible life, so perhaps we might live there.

B. It's almost as hot as and as large as Earth.

C. In the future，scientists will study the chemicals of it by telescope.

D. It's an Earth﹣like planet.

3.What is the best title of the passage？

A. Space research

B. Journey to space

C. Is there water and possible life in Kepler﹣186f？

D. Scientists discover the most Earth-like planet

The possibility that pleasant smells might reduce pain has recently been suggested by new research. In a scientific study, doctors asked 20 men and 20 women to keep their hands in very hot water for as long as possible while breathing in different smells.

As people believe that strong smells can affect the senses, volunteers were asked not to eat or drink for eight hours before the experiment began. During the experiment, volunteers were asked to take in pleasant smells such as vanilla (香草), and unpleasant smells such as durians (榴莲). The volunteers kept their hands in the water until it became too hot for them. When they could not bear the pain any more, they took their hands out of the water.

Scientists are interested in whether the senses or smell is related to pain and whether men and women have the same senses. Now, the study has proved that for women, pleasant smells reduce pain. For men, there is no change.

Dr Finkelstein has been studying smells since 1999. He says that scientists already have data from 40 volunteers. He adds that this year, scientists will test another 60 volunteers and will be in a better position to explain the results.

One explanation is that women’s sense of smell developed long ago, and is linked to recognizing the smell of babies. Scientists used to believe that mothers recognized their children by sight only. Now, they have started to believe that the sense of smell also helps, but why pleasant smells do not reduce pain in men is a question still to be answered by scientists.

1.Before the experiment, volunteers ______.

A．are gathered and take a training

B．cannot eat or drink for several hours

C．must wash their hands carefully

D．will be interviewed by Dr Finkelstein

2.If both men and women are asked to keep their hands in hot water while taking in some pleasant smells, ______.

A．women may stand the pain of the hot water longer

B．men may keep their hands in the hot water longer

C．they will probably take their hands out at the same time

D．we are not quite sure who will take their hands out earlier

3.From the passage we learn that _________.

A．the reason why women are sensitive to smells is clear

B．the experiment for the sense of smell has come to an end

C．unpleasant smells affect men’s senses more than women’s

D．scientists have not totally explained the result of the study

4.Now scientists believe that _______.

A．mothers recognize their children only by sight

B．men’s sense of smell developed a long time ago

C．strong smells have a great influence on people’s senses

D．smells are helpful for mothers to spot their children

5.The writer wrote the passage in order to ________.

A．supply some entertainment to us

B．show women’s sharper senses than men’s

C．inform the readers of some knowledge

D．call for volunteers for the experiment

The earth is the only planet that scientists think has life. Why does the earth have life while the other planets (行星) don't? For one thing, the earth is just the right temperature. As the_third_planet from the sun, the earth seems to be just the right distance away. The planets which are closer to the sun are hot that their surfaces bake (烘烤) in the sun. The farthest planets are cold balls.

When the earth developed — which scientists believe may have happened about 4 billion years ago — many gases covered the earth. The gases caused the earth to be hot. But something wonderful happened. The temperature was just right for thick clouds to form. It rained very hard for a very long time. This gave the earth its oceans. Water made it possible for plants to grow. The plants created oxygen in the atmosphere. Oxygen is the gas that humans and animals breathe.

Only one other planet in the solar system seems to be something like the earth. That planet is Mars (火星). Mars is smaller than the earth, and it is quite a bit cooler. But it is not too cold for humans. On some days, the temperatures are as low as a winter day in the northern United States. If you wore a special space suit, you could walk around on Mars. You would have to bring your own air to breathe, the air on Mars is too thin to breathe.

Mars has the largest volcano (火山) in the solar system. It is sixteen miles high. The highest volcano on the earth is five miles high. The most unexpected (未预测到的) sight on Mars is dried up river beds. Scientists believe that Mars was once much better than it is now. Does this mean there could have been living things on Mars? Scientists are not sure, but there has been no sign so far.

1.Which of the following is NOT the reason that the earth has life?

A. The earth is just the right temperature.

B. The volcanos on earth are lower than those on Mars.

C. There is oxygen in the atmosphere of the earth.

D. The earth seems to be just the right distance away from the sun.

2.The underlined phrase “the third planet” in the first paragraph refers to ________.

A. the Sun　　　　　　　　　     B. the Moon

C. the Earth　　　　　　　　     D. the Mars

3.Which of the following about the Mars is NOT true?

A. There could have been living things on Mars.

B. Mars has the largest volcano in the solar system.

C. There is almost no oxygen in the air on Mars.

D. Mars is smaller than the earth, and it is quite a bit cooler.

In her 17 years on this earth, Shreyaa Venkat has done more to help the planet and the people living on it than many adults. The non-profit organization she founded, NEST4US, has helped tens of thousands of people in the United States. Through it, it’s served over 12,000 homeless people in the Washington, D.C. area by providing food and other supplies.

Venkat’s passion for helping others started as soon as she could walk, as her parents, active volunteers themselves, brought her along on their various projects, like some creative ways to volunteer. By fifth grade, she’d developed such enthusiasm for it that she started organizing her own service projects in her community.

NEST4US was born when she realized how much food waste there is, how many hungry people there are, and how simple it would be to use the former to help the latter. “There was a homeless man standing on a corner in D.C. and he was holding a sign that said ‘Hungry Need Food’,” she recalls. “So I gave him my lunch and his whole face just lit up. It was so easy, it only took me 30 seconds, and it really helped him.”

As NEST4US took off, with hundreds of volunteers helping to feed thousands of hungry people, Venkat decided to branch out with her volunteer efforts, starting three other branches of NEST4US. Serving others had become such a way of life for her that she even celebrated her 13th birthday at a homeless shelter, bringing the party to them instead of expecting gifts for herself.

As much as she has helped others, they’ve helped her too. Not only does she get a lot of joy and personal satisfaction from her volunteer work but running NEST4US has taught her important life skills like time management, public speaking, writing, and leadership. “What it’s really given me is this opinion of putting other people first,” she says.

1.What can we infer about NEST4US from the first paragraph?

A.Its main aim is to make money. B.It offers people cheap supplies.

C.It takes in all homeless people. D.It is a charity organization.

2.What caused Venkat to set up NEST4US?

A.Her parents’ constant suggestion. B.The memory of her hard childhood.

C.Her experience of helping a hungry man. D.Volunteers’ great influence on her.

3.Why did Venkat spend her 13th birthday at a homeless shelter?

A.She held a grand party for many people.

B.She could receive many nice gifts there.

C.She got much personal satisfaction from it.

D.She saw helping others as part of her life.

4.Which of the following best describes Shreyaa Venkat?

A.Caring. B.Ambitious.

C.Humorous. D.Demanding.

New technology links the world as never before. Our planet has shrunk（收缩）. It’s now a “global village” where countries are only seconds away by fax or phone or satellite link. And, of course, our ability to benefit from this high-tech communication’s equipment is greatly enhanced by foreign language skills.

Deeply involved with this new technology is a breed of modern businesspeople who have a growing respect for the economic value of doing business abroad. In modern markets, success overseas often helps support domestic(国内的) business efforts.

Overseas assignments are becoming increasingly important to advancement within executive(行政的) ranks. The executive stationed in another country no longer need fear being “out of sight and out of mind.” He or she can be sure that the overseas effort is central to the company’s plan for success, and that promotions often follow or accompany an assignment abroad. If an employee can succeed in a difficult assignment overseas, superior will have greater confidence in his or her ability to cope back in the United States where cross-cultural considerations and foreign language issues are becoming more and more common.

Thanks to a variety of relatively inexpensive communications devices with business applications, even small businesses in the United States are able to get into international markets.

English is still the international language of business. But there is an ever-growing need for people who can speak another language. A second language isn’t generally required to get a job in business, but having language skills gives a candidate(候选人) the edge when other qualifications appear to be equal.

The employee posted abroad who speaks the country’s principal language has an opportunity to fast-forward certain negotiations, and can have the cultural insight to know when it is better to move more slowly. The employee at the home office who can communicate well with foreign clients(客户) over the telephone or by fax machine is an obvious asset to the firm.

1.What is the author’s attitude toward high-tech communications equipment?

A. Critical.                   B. Indifferent.               C. Negative.                 D. Positive.

2.With the increased use of high-tech communications equipment, business people_________.

A. have to get familiar with modern technology

B. are gaining more economic benefits from domestic operations

C. are placing more importance on their overseas business

D. are eager to work overseas

3. In this passage, “out of sight and out of mind” (Para. 3) probably means _________.

A. being unable to think properly for lack of insight

B. being totally out of touch with business at home

C. missing opportunities for promotion when abroad

D. leaving all care and worry behind

4.According to the passage, what is an important consideration of international corporations in employing people today?

A. Connections with businesses overseas.     B. Ability to speak the client’s language.

C. Technical know-how.                             D. Business experience.
