Everyone knows about straight-A students. We see them frequently in TV situation comedies and in movies like Revenge(报复)of the Nerds. They get high grades, all right, but only by becoming dull laborers, their noses always stuck in a book. They are not good at social communication and look clumsy while doing sports.

How, then, do we account for Domenica Roman or Paul Melendres?

Roman is on the tennis team at Fairmont Senior High School. She also sings in the choral group, serves on the student council and is a member of the mathematics society. For two years she has maintained A’s in every subject. Melendres, a freshman at the University of New Mexico, was student-body president at Valley High School in Albuquerque. He played soccer and basketball well, exhibited at the science fair, and meanwhile worked as a reporter on a local television station. Being a speech giver at the graduation ceremony, he achieved straight A’s in his regular classes, plus bonus points for A’s in two college-level courses.

How do super-achievers like Roman and Melendres do it? Brains aren’t the only answer. “Top grades don’t always go to the brightest students, ” declares Herbert Walberg, a professor of education at the University of Illinois at Chicago, who has conducted major studies on super-achieving students.“Knowing how to make the most of your innate(天生的)abilities counts for more. Much more.”

In fact, Walberg says, students with high IQ sometimes don’t do as well as classmates with lower IQ. For them, learning comes too easily and they never find out how to get down.

Hard work isn’t the whole story, either.“It’s not how long you sit there with the books open, ” said one of the many-A students we interviewed.“It’s what you do while you’re sitting.”Indeed, some of these students actually put in fewer hours of homework time than their lower-scoring classmates.

The kids at the top of the class get there by mastering a few basic techniques that others can readily learn.

1.The underlined word “nerds” can probably be________ .

A．dull bookworms lacking sports and social skills

B．successful top students popular with their peers

C．students with certain learning difficulties

D．born leaders crazy about social activities

2.What can we conclude from the first paragraph?

3.Some students become super-achievers mainly because_________ .

A．they are born cleverer than others

B．they work longer hours at study

C．they make full use of their abilities

D．they know the shortcut to success

4.What will be talked about after the last paragraph?

A．The interviews with more students.

B．The role IQ plays in learning well.

C．The techniques to be better learners.

D．The achievements top students make.

5.What can we infer from the passage?

A．IQ is more important than hard work in study.

B．The brightest students can never get low grades.

C．Top students certainly achieve all-around developments.

D．Students with average IQ can become super-achievers.

Researchers in over 80 nations are taking part in a project to conduct a decade-long census(统计) of sea life. Scientists presented some of their findings at a recent conference as the project neared its completion.

In deep icy waters under Antarctica, scientists found bulbous tunicates, an underground animal, and many newly-discovered creatures believed to be related to starfish (海星) and other marine(海洋的）creatures.

Elsewhere in the world’s oceans, they have recently discovered many kinds of underwater life forms new to science. It is all part of a research effort called the Census of Marine Life.

“There are about 2,000 scientists worldwide involved,” said Bob Gagosian, President, CEO of the Consortium for Ocean Leadership. Gagosian helps manage the project. “Everywhere they’ve gone they’ve found new things,” he says. “The ocean basically is unexplored from the point of view of marine living things.”

Researchers have placed small markers on hundreds of fish and marine animals to track by satellite their migration(迁移）routes and to discover places where sea life gathers.

According to Ron O’Dor, a senior scientist with the Census of Marine Life, knowledge of life on the ocean floor is especially limited. “90% of all the information we have is from the top hundred meters of the ocean,” O’Dor states.

And he says the sea floor is, on average, at a depth of 4, 000 meters. And so, as some machines dive far below what people have previously seen, scientists are discovering new species of plants, animals and living things.

Since the census project began, more than 5,300 new marine animals have been found. Ocean researchers say they hope to catalogue 230,000 species during the census —which some say is only a small part of all the creatures living in the sea.

1.Why do the researchers place small markers on many marine creatures?

A．To catch them.	B．To research them.
C．To kill them.	D．To protect them.

2.From what Ron O’Dor says, we can conclude that .

A．human beings only know a little about marine life

B．the oceans don’t need to be further explored

C．he considers exploring the ocean a dangerous thing

D．the marine creatures mainly live on the top of the ocean

3.What can we learn from the passage?

A．About 2,000 scientists from America are involved in the project.

B．The census of sea life will last for ten years.

C．230,000 new marine animals have been found.

D．The sea floor is at a depth of 400 meters.

4.Why does the author write the passage?

A．To tell the news that new marine creatures are being discovered

B．To encourage people to find new marine creatures

C．To prove the importance of marine creatures

D．To introduce the newly-discovered creatures.

_______ from the top of the mountain, we found the city more beautiful.

A．Seen

B．Having been seen

C．Seeing

D．Being seen

A breathtaking trick potentially left over from our ancestors might be found in us — the ability to sense oxygen through our skin.

Amphibians, animals such as frogs that can live both on land and in water, have long been known to be capable of breathing through their skin. In fact, the first known lungless frog that breathes only through its skin was discovered recently in the rivers of Borneo.

Now the same oxygen sensors found in frog skins and in the lungs of mammals (哺乳动物) have unexpectedly been discovered in the skin of mice.

“No one had ever looked,” explained Randall Johnson, a biologist researcher.

Mice and frogs are quite distant relatives, so the fact they have these molecules (分子) in common in their skin suggests they might well be found in the skin of other mammals, such as humans.

“We have no reason to think that they are not in the skin of people too,” Johnson said. These molecules not only detect oxygen, but help increase levels of vital red blood cells, which carry oxygen around the body. Normal mice breathing in air that is 10 percent oxygen—a dangerously low level similar to conditions at the top of Mount Everest, and about half that of air at sea level. However, mice that had the oxygen sensor HIF-1a genetically removed from their skin failed to produce this hormone (荷尔蒙) even after hours of such low oxygen.

These findings, if they hold true in humans, suggest one could raise the level of oxygen circulating inside the body. This could help treat lung diseases and disorders such as anemia (贫血症) without injecting drugs, which make up a multibillion-dollar market, Johnson said.

Athletes also often try to get more oxygen delivered to their muscles in order to improve their performance. They often do this by training at high altitudes or in low-oxygen tents. The new study suggests they might want to expose their skin as well as breathing in low-oxygen air to improve their performance. “It’s hard to say what exactly might be done, however—there’s a lot we don’t know yet,” Johnson explained.

The scientists detailed their findings in the April 18 issue of the journal Cell.

49. Which of the following statements is TRUE according to the passage?

A. Johnson believes that Oxygen sensors also exist in human skin.

B. People have to surf the Internet to read detailed findings.

C. It has been proved that these findings help treat lung diseases.

D. It has long been expected oxygen sensors exist in mice’s skin.

50. One of the functions of the molecules mentioned above is _______.

A. carrying oxygen around the body B. improving athletes’ performance

C. detecting oxygen D. increasing level of oxygen

51. What is Johnson’s attitude to the application of the findings to the athletes’ training?

A. Negative B. Doubting C. Positive D. Hesitating

52. The best title of the passage may be _______.

A. Great Findings Benefits Athletes A Lot

B. Frogs And Mice Are Distant Relatives

C. First Known Animal Breathes Through Skin

D. Humans Might Sense Oxygen Through Skin

Microsoft founder Bill Gates has recovered his spot at the top of the US money heap, taking the place of Investor Warren Buffett as America's richest person, Forbes magazine's latest list reveals.

With 57 billion dollars net worth Gates again leads the list of 400 richest individuals in the world’s wealthiest country. He displaced Buffett who briefly held the position this year but who has seen his Berkshire Hathaway investment group's shares slip 15 percent since February and is now worth 50 billion.

According to Forbes, whose list was published late Wednesday, the golden 400 have 1.3 billion dollars net worth or more. However, their combined net worth rose only 30 billion dollars, or two percent, to 1.57 trillion dollars.

Forbes said that rising oil and dizzy art prices fuelled the entry of 31 new members into the ultra -rich club and the return of eight previous members.

A notable arrival was Mark Zuckerberg, 24, founder of the social networking site Facebook (脸谱网). Forbes estimates his worth at 1.5 billion dollars.

Meanwhile, turmoil (动荡) on the stock and housing markets saw 33 others drop off the list, including former head of the troubled insurance giant AIG, Maurice Greenberg, and a former head of the online auction site eBay, Margaret Whitman.

Biggest gainers were led by New York Mayor Michael Bloomberg who took eighth place with 20 billion dollars worth after a transaction (交易) put a new value on his Bloomberg media and financial data network.

The biggest loser was casino (赌场，娱乐场所) tycoon Sheldon Adelson, whose fortune fell 13 billion dollars over 12 months -- the equivalent to 1.5 million dollars an hour -- although he still has 15 billion dollars and occupies 15th place.

About two thirds of the list are self-made billionaires and just over 10 percent are women, led by television star Oprah Winfrey whose fortune rose 200 million dollars to 2.7 billion dollars.

68. According to Forbes, Warren Buffet is worth ________.

A. 57 billion dollars B. 50 billion dollars C. 1.5 billion dollars D.20 billion dollars

69. 31 new members entered the ultra-rich club as a result of ________.

A. turmoil on the stock and housing market

B. media and financial data network
