Recently, a number of studies found that future reductions of sea ice could result in a loss of many polar bears within fifty years. The studies found a direct link between sea ice in the Arctic Ocean and the health of polar bears. The scientists say the animals will disappear from the north coasts of Alaska and Russia in the next fifty years. The only polar bears to survive will be in Canada's far north and the west coast of Greenland.

The scientists found that almost two thirds of the world's nineteen polar bear populations will disappear from the earth by the middle of this century. The studies showed that three more groups of polar bears will disappear within seventy-five years.

Scientists say polar bears still can be saved. But they say the world must begin taking steps to reduce climate change to do this. The center for Biological Diversity says governments around the world need to reduce the release (释放)of pollution like C02 gas.

Scientists say one step toward this goal would be to include polar bears on America's list of endangered species. Then the government would be able to make sure that industrial activities do not threaten their survival. The United States Fish and Wildlife Service is expected to examine the new findings when it considers whether polar bears should be included on the Endangered Species List.

A picture of a set of eyes on a computer screen can cause a change in the way people act. Even images of eyes on a charity do-nation, a collection box encourages people to be unselfish, because people put more money in a collection box that has a picture of eyes on it than they do when a flower symbol is on the box.

Manfred Milinski from the Max-Planck Institute for Evolutionary Biology in Germany and Bettina Rockenbach of the University of Berlin, the authors of a new study, found that people act better when they are being watched be-cause they feel they will be rewarded for good behavior. Their report also referred to other research showing that this response of behaving well when watched is somehow coded into humans and people respond this way unconsciously, or without realizing it.

It is not just humans that act unselfishly when they are being watched. A fish called the grooming fish cleans other fish. When other fish are around, it is gentler. When no other fish are around, however, the grooming fish bites chunks from the fish it is supposed to be cleaning.

The researchers suggest that the best way to get people to be-have in the correct way is to make them feel watched. This could be the reason for the success of a famous American army poster. On it was a icture of an elderly man staring fiercely and pointing, it appeared, to the person who was looking at the poster. Under the picture was the caption " I Want You. " It encouraged hundreds of thou-sands of young American men to join the army during the Second World War to fight the Germans and Japanese.

Audrey Zhang，a fifth-grader from Levittown，N．Y，is the winner of this year’s Doodle 4 Google contest，rising to the top of some 100，000 entries on the theme of“draw one thing to make the world a better place．”

Her piece，titled“Back to Mother Nature，”describes a detailed water-cleaning machine．Zhang worked with a team of artists at Google to animate(使……生动)her drawing．

“To make the world a better place，I came up with a transformative water purifier, a machine used to remove dirty or harmful substances，”Google quoted Zhang as saying．“It takes in dirty and polluted water from rivers，lakes and even oceans，then massively transforms the water into clean，safe and pure water. When humans and animals drink this water, they will live a healthier life．”

She created a whole world around the device—one populated by humans， a whale in a top hat and dragons．

Zhang，s piece is“so vivid and so rich and so full and so complete，’’Google Doodle team leader Ryan Germick told the Washington Post．“Every leaf seemed to have life in it．”

Along with having her artwork featured on Google’s homepage，Zhang wins a $30，000 college scholarship．In addition，her school will receive a $50，000 Google for Education technology grant，and the company is donating $20，000 in her name to a charity devoted to bringing clean water to schools in Bangladesh．

On Sunday, the night before her work was revealed on net，Zhang told Newsday she was excited by the big win，but said she wouldn't be awake when her art first went online at midnight．

“I have school-tomorrow, so I can’t stay up late，”she told the paper．

【1】What’s the passage mainly about?

A．The winner and her work in the painting contest．

Christine was just a girl in one of my classes. I never knew much about her except for that she was strange. She didn't talk many. Her hair was black and purple, and she worn black sports shoes and a black sweater, although in the summer, she was, in fact, rather attractively, and she never seemed care what the rest of us thought about her. Like the rest of my classmate, I didn't really want to get closest to her. It was only when we did their chemistry project together that I begin to understand why Christine dressed the way she did.

When I was ten years old, I went to Yangzhou with two American. I became their guide. First, we went to the Shouxi River. They wanted to look around the river by the boat. After buy the tickets, we got into the boat. We went around seeing the beautiful sight. After that, we went shopping. The sellers couldn't spoke English. Though it was very harder, I tried my best listen to their words carefully and translate the sentences. They bought some little things with their help. Next, we went to a small zoo but took some pictures. When we felt hunger, we went out and had lunch. After lunch, we visited some old house and learned more about Chinese history.

Dear Brown，

Last summer I take a part－time job in the International Camp for children. have been told one more worker will be needed in this year and I think you are fit to it. How about join us? The camp is at the foot of a small hill close to a river. It is so a beautiful place ! We can hear birds singing happy all around. Everybody sleeps in tents, that is very exciting. We usually work only five hours a day, so we will have plenty of spare time visit the area and have a fun. I am sure it will be an unforgettable experience. If you have interests in it, reply to me soon.

Wind tunnels are basically tubes through which air—or a gas—is moved to make “wind” in the tube. This “wind” moves past objects such as airplanes or just parts from airplanes.

It s always a good idea to test a new aircraft design in a wind tunnel before you build the real aircraft. Models tested in wind tunnels will always go through design changes before engineers are satisfied with its design and test results.

Wind tunnels are constructed with some very wide sections as well as some sections much smaller in size. An “open return wind tunnel”is open at both ends of the tube. It is usually largest at one end of the tube where you may even see the fan blade(风扇片)that creates the wind. This tube gets smaller as you move away from the fan blade. The tube begins to straighten in the next part of the wind tunnel called the Test Section. This is where you place the model for testing. The tube widens again as you move away from the Test Section.

Another wind tunnel is the “closed return” design. This tunnel is completely contained inside a building. The tunnel moves in a “loop” inside the building. A fan is located in the tunnel on one side of the building and the test model is located in the tunnel's Test Section on the other side of the building.

NASCAR race teams even test their race cars in wind tunnels to test and improve a car's design. These teams work hard to reduce a car's drag. In less than 150 years, wind tunnels have allowed mankind to improve cars on the ground, aircraft in the atmosphere, and spacecrafts in space. We can only imagine what will happen with wind tunnels during the next hundred years.

【1】What could be the best title of the passage?

A．What Are Wind Tunnels Made of?

B．What Is a Wind Tunnel and How It Works?

C．Where Can Wind Tunnels Be Found?

D．Why Are Wind Tunnels Used?

【2】Which of the following is the right shape of an “open return wind tunnel”？

【3】In the “close return” wind tunnel, the fan is fixed________.

A．in the Test Section on the other side of the building

B．next to the models in the building

C．at one end of the opening

D．on the other side of the Test Section

【4】By reducing a race car's drag, ________.

A．the car will becomes lighter

B．the car will be easy to operate

C．the car will move faster

D．the car will look more beautiful
