Just ask the polar bears of Hudson Bay.In arctic regions the polar bear is the top of the food chain. Its scientific name, Ursus maritimus means “bear of the sea”. This describes the way the animal earns its living. It hunts on and from sheets of ice floating in arctic seas. In the farthest north regions, there is sea ice all the year round. But there is one polar bear colony that feeds around the southwest shores of Canadas Hudson Bay. There the ice breaks up in spring and freezes again in fall. In between, the bears have trouble finding food. Their big feast comes in the spring, just before the breakup. They go out on the ice floes(浮冰块) to hunt their favorite food, seal. A large bear may eat 150 pounds of seal meat in a day. The energy they store helps the bears stay alive until the November freezes.Recently, however, the ice has been forming later in the fall and breaking up earlier in the spring. Thats because temperatures around Hudson Bay have been gradually rising. Near the town of Churchill, they have gone up about 2.5 Fahrenheit since 1950. This means that the bears feeding season has shortened by about three weeks. That makes things hard for the bearsand potentially dangerous for their human neighbors. In 1984 a Churchill man was attacked and killed by a polar bear.The danger doesnt keep animal lovers from coming to Churchill to see the bears. They take pictures from bear-proof vehicles, snowmobiles, and helicopters. Wildlife wardens (看守人) patrol the area to keep bears away from the town.But both the tourists and the people of Churchill wonder how long the bears will remain. The amount of ice in Hudson Bay is about one-third less than it was 30 years ago. In another 30 years, if temperatures keep rising at the same rate, the ice-free season could be three months longer than it is today. The climate could change from tundra(寒带草原) to forest. Many animal and plant species would have to move north to survive.“The nations of the world need to do something about global warming,” said one tourist photographing bears on the tundra near Churchill. “The polar bear is the living symbol of the Arctic. If we lose this habitat, well lose the bears. I dont like to even think about what that could mean.”56. The bears have difficulty in finding food _.A. in spring B. in fall C. in summer D. in winter57. As temperatures around Hudson Bay gradually rise, _.A. bears can find food more easilyB. hungry bears will be a danger to their human neighborsC. fewer bear lovers dare to go to the Arctic regionD. bears can live longer58. From the passage, we learn that _.A. no other animal can defeat and eat bears in Arctic regionB. global warming has little influence on the living habitat of the polar bearC. in 60 years the ice-free season could be three months longer than it is today if temperatures keep rising at the present rate.D. the polar bear is an animal that reminds us of the Antarctic(B)Remember your first romantic disappointment? Remember the pain and unhappiness of breaking-up uncertainty? Winne recalls feeling very sad after her first true love deserted her. “My mom came into my room carrying a beautiful nightgown and handed it to me, gave me a hug and said, I know you are feeling very heartbroken. I thought you could use something to make you feel beautiful right now.” The nightgown didnt make Winnes hurt go away, but she knew that her mother understood and cared about her feelings.As a parent, as much as you want to make it all better for your teen, give them space. Tell him or her that break-ups are hard and you are there for him whenever he wants to speak to you. Then let go.Teenage girls often deal with break-ups by talking on the phone with their friends or diving into the Internet for a long chat. They review all the hurts and pains which are being cured. Boys react to broken relationships differently. Boys often become angry since that, unfortunately, is the only emotional (感情) choice that society accepts for boys. Some boys hide their pain. Respect your teen, when a relationship breaks up. It takes time to get over it, and the only way to get through that is to get through it.Sometimes teenagers get into trouble while trying to feel accepted again or win back a loved one. Keep reaching out to troubled teenagers. At first, teens will refuse a parents attempts to help. Dont be afraid to insist.Teen break-ups can cause heart-wrenching pain, but sooner or later teenagers should be ready to date(约会) again. How can you make your child toward a healthy relationship? Teens are likely to meet others like themselves through activities. The secret to attracting good boys or girls is to become your own independent person who feels good about who she or he is.59. The beautiful nightgown Winnes mother handed to her _.A. made her heart broken.B. made her feel beautiful right now.C. didnt make her feel better.D. made her understand her mother.60. In the first paragraph, the underlined word “uncertainty” means _.A. doubt B. unreturned loveC. pain and unhappiness of breaking up D. dissatisfaction61. Which of the following is Not True according to the passage?A. Parents should be patient with their children, be a good listener and help them.B. Teenage girls like to talk with friends and engage themselves in a long chat on the Internet when broken relationships happen to them.C. Boys are usually becoming angry or hiding their pain which people think is normal.D. Teenagers always refuse parents attempts to help when they are in trouble.62. If you want to find a true friend, _.A. go to take part in all kinds of activities.B. date a boy secretly.C. dont trust others.D. try to be a true “yourself” when you get along with another.（C）You need the following things to carry out the experiment: scissors, white paper, coffee filter (滤纸), black marker (记号笔), water, coffee cup.What do you do?Cut a circle out of the coffee filter. (It doesnt have to be a perfect circle, just a round shape that s about as big as your spread - out hand)With the black marker, draw a line across the circle, about 1 inch up from the bottom.Put some water in the cup enough to cover the bottom. Curl the paper circle so it fits inside the cup. Make sure the bottom of the circle is in the water. Watch as the water flows up the paper. When it touches the black line, youll start to see some different colors.Leave the paper in the water until the colors go all the way to the top edge. How many colors can you see?How does Black Magic work?Most nonpermanent markers use inks that are made of colored pigments (颜料) and water. When you dip the paper in water, the dried pigments dissolve. As the water travels up the paper, it carries the pigments along with it. Different-colored pigments are carried along at different rates; some travel farther and faster than others. How fast each pigment travels depends on the size of the pigment molecule(分子) and on how strongly the pigment is attracted to the paper. Since the water carries the different pigments at different rates, the black ink separates to show the colors that were mixed to make it.In this experiment, youre using a technique called chromatography (色层分离法). By examining where all the ingredients(成分) ended up, scientists can figure out what was combined to make the mixture.63. It can be inferred that you need the scissors_.A. to put the filter in the cupB. to cut the filterC. help to draw a line across the filterD. measure the distance of the line from the bottom64. In order to do the experiment well, _.A. you need to fill the coffee cup with waterB. you need to make the coffee cup half full of waterC. you need to put enough water to cover the black line on the circle completelyD. you only need to put enough water to cover the bottom of the circle65. This passage is probably meant for_A. young students B. scientists C. painters D. teachersV. 短文改错：（每题1分，共10分）Nowadays, paper still come from trees. Unfortunately, we use a 66._lot of paper every day.
