More than 1,500students from across the country entered projects in the competition this year. Their research included chemistry, medicine, physics, mathematics, engineering, and computer science-almost every area of science.
Forty students were invited to Washington, D.C. for the final judging. A group of scientists judged them on their research abilities, critical thinking skills and creativity. The judges also questioned the students about scientific problems before deciding on the winners.
The top winner received 100,000 dollars for college. Shannon Babb of American Fork High School studied the water quality of tile Spanish Fork River in Utah for six years. She found that people have a harmful effect on the river through human activity, including agriculture. And she suggested ways to improve the water quality in the future. These include educating the public not to put household chemicals down the drains（下水道）, which lead to the river eventually.
Seventeen-year-old Yi Sun of the Hanker School in San Jose, California, earned the second place. He won a 75,000-dollar scholarship for new discoveries about a mathematical theory known as random walks. His work could help computer scientists and chemists. Yi Sun was born in China.
The third-place winner was also seventeen and born in China. Yuan “Chelsea” Zhang of Montgomery Blair High School in Rockville, Maryland, won a 50,000-dollar scholarship. She researched the molecular genetics（分子遗传学）of heart disease. Her findings could aid the development of new medicines.
The Intel Science Talent Search is the oldest science competition for high school students in the United States. It is 65 years old this year. Past winners have gone on to receive six Nobel prizes and other top honors in science and math.

Norway—Ten Chinese college students arrived at the country’s Arctic research base, the Yellow River Station, on Friday.
On Saturday，the students are expected to witness the end of four months of darkness in the area, as the sun makes a rare appearance.
During their four-day stay at the station，the students will meet and learn from some of China’s leading polar researchers．They were welcomed at the station yesterday by its director，He Jianfeng, who is an expert on marine micro-ecosystems．

The kiwi bird is a flightless bird，about the size of a chicken. It sleeps during the day and is active at nighttime. It has a long beak that is onethird the length of its body, and its beak actually has nostrils (鼻孔) at the end. The kiwi is the only bird with this feature. Another unique feature of the kiwi is that it has no tail. It has thick brown hairlike feathers. This bird has many physical features unlike any other bird on earth.
Kiwi birds have been called a genetic leftover. Their characteristics seem very odd to us probably due to the fact that they haven"t evolved much at all. They are suspected to be about 8 million years old. That"s 7 million years older than humans. Due to New Zealand"s isolated environment, it has been safe from predators(食肉动物) and hasn"t needed to do much adapting. They just hang around.
With its long beak, the kiwi digs up and chows down on worms. A kiwi is almost blind; it can see about six feet at night and around two feet during the day，so when it comes to hunting the kiwi is not well equipped.It uses the nostrils on its beak to find its food and then picks up the worms with its beak.
The kiwi bird is native of New Zealand.It is the island country"s national bird, and is rare anywhere but here and a few Pacific island neighbors. Of course，it is available for viewing at certain zoos.It has stayed in its native land due to the facts that it is an isolated island and that kiwis can"t fly.
Kiwi birds are extremely unique in the bird world. Though they are the size of chickens, they lay eggs the size of ostrich eggs, weighing around a pound each.Their enormous eggs are the largest in the bird world, compared to their bodies. These birds were named after their distinctive shrill cry “keewee keewee”．
小题1:Which of the following is NOT the distinctive feature of the kiwi bird?

| A．the climate is mild |
| B．they have no enemy |
| C．something is wrong with their genes |
| D．they have adapted to living on the island |
| A．Its long beak. | B．Its eyes. |
| C．The nostrils. | D．Its tail |
| A．The kiwi bird"s habitat. |

The Ministry of Health and health department of the People"s Liberation Army General Logistics Department jointly announced the campaign at a conference.Both departments also ordered all of their local branches to suspend permits for new organizations that wish to offer ART treatments.That is，new organizations will not appear recently.Official figures showed that at the end of 2012，China had 358 organizations authorized to conduct ART treatment.

“It"s the next ‘wow’ vehicle，” said Terrafugia，vice president Richard Gersh.“Anybody can buy a Ferrari，but as we say，Ferraris don"t fly.”
The carplane has wings that unfold for flying—a process the company says takes one minute—and fold back up for driving.A runway is still required to take off and land.
The Transition is being marketed more as a plane that drives than a car that flies，although it is both.The company has been working with FAA to meet aircraft regulations，and with the National Highway Traffic Safety Administration to meet vehicle safety regulations.
The company is aiming to sell the Transition to private pilots as a more convenient and cheaper way to fly.They say it saves you the trouble of trying to find another mode of transportation to get to and from airports：you drive the car to the airport and then you"re good to go.When you land，you fold up the wings and hit the road.There are no expensive parking fees because you don"t have to store it at an airport—you park it in the garage at home.
The carplane is designed to fly primarily under 10,000 feet.It has a maximum takeoff weight of 1,430 pounds，including fuel and passengers.Terrafugia says the Transition reduces the potential for an accident by allowing pilots to drive under bad weather instead of flying into marginal(边缘的) conditions.
The Transition"s price tag：$194,000.But there may be additional charges for options like a radio，transponder or GPS.Another option is a fullplane parachute.
“If you get into a very awful situation，it is the necessary safety option，”Gersh said.
So far，the company has more than 70 orders with deposits.“We"re working very closely with them，but there are still some remaining steps，” Brown said.
小题1:We can learn from the first paragraph that ________.
| A．carplanes will be popular in 2012 |
| B．people might drive a carplane in 2012 |
| C．both the Transition and the Ferrari can take off and land |
| D．Richard Gersh is the vice president of Massachusetts |
| A．fold and unfold its wings |
| B．unfold wings for flying |
| C．land in the airport |
| D．meet flying safety regulations |
A．The carplane needs a runway to take off and land.
B．To meet aircraft regulations，the company has been working with FAA.
C．The carplane may fly as high as normal planes.
D．People can park the carplane in the garage at their home.
小题4:The underlined word “it” in the last but one paragraph refers to ________.
| A．the radio |
| B．the transponder |
| C．the GPS |
| D．the fullplane parachute |
Chen’s cave is 20 meters wide and 8 meters deep. Lichens (青苔)can be seen everywhere in it. Chen says that the place is free of pollution.
Because of being poor, they moved into the cave, Chen said. In 1975, the houses of his families and his neighbors were all burned to the ground in the fire. Chen was then already married and badly needed a house to live in. But he had no money to build a house, so he had to live in his relatives’ houses as long as 5 years.
In 1980, he happened to discover this cave, immediately he and his family members decided to live in there. Chen thought the cave could be a temporary（临时的）living place, but it never occurred to him that it could be his home in the next 28 years. Chen recalled that the first couple of days were the most difficult period, “I put up some wooden boards for a gate, but they were all blown away by wind that same night.”
Chen has two sons and a daughter, and they all left the cave after they got married. Now Chen’s old friends once in a while visit him in his cave drinking and playing Chinese chess. For Chen, the most enjoyable thing is to raise bees and grow kinds of plants.
