The temperature is rising again in the Arctic. The sea ice area has dropped to one of the lowest levels on record， climate scientists reported last week.
“The new Arctic Report Card tells a story of widespread and continued effects of a warming Arctic，” said Jackie Richter-Menge of the US’s Cold Regions Research and Engineering Laboratory.
“This isn’t just a climatological (气候学的) effect. It impacts the people that live there，” she added.
Scientists concerned about global warming focus on the Arctic because that is a region where the effects are expected to be felt first， and that has been the case in recent years.
There was a slowdown in Arctic warming in 2009， but in the first half of 2010 warming was near a record pace. The monthly readings were over 4 degrees Celsius above normal in northern Canada， according to the report card. The report card was prepared by 69 researchers in eight countries.
Researchers said last winter’s big snow storms that struck some Northern countries were tied to higher Arctic temperatures.
“Normally the cold air is bottled up in the Arctic，” said Jim Overland of the US National Oceanic and Atmospheric Administration. “But last December and February， winds that normally blow west to east across the Arctic were instead bringing the colder air south，” he said.
“As we lose more sea ice... warming in the atmosphere can create more of these winter storms，” Overland said.
There is a powerful connection between ice cover and air temperatures， Richter-Menge explained. When temperatures warm， ice melts. When ice melts it shows darker surfaces underneath ， which absorb more heat. “That， in turn， causes more melting and on the cycle goes，” she said.
In September the Arctic sea ice extent was the third smallest in the last 30 years， added Don Perovich of the US Army Laboratory. He said the three smallest ice covers have occurred in the last four years. Scientists care so much about the warming in the Arctic region because .

One Canada, Two Languages
Canada is one of the few nations in the world to have two official languages: English and French. There are 10 provinces in the country but only one of these—Quebec is known as “French Canada”. This is because it was founded by French explorers while British adventurers discovered the rest.
Canada left the British empire(帝国) in 1867 to become an independent country and English and French have been recognized as the official languages ever since.
Most people speak English as their first language and the two national television networks broadcast in English throughout the country. Apart from in Quebec and a few places on the east coast, French television is very rare.
The same goes for traffic signs and menus, for example, outside of Quebec, there are only a few places where you’ll see traffic signs in French. In restaurants, it’s almost impossible to find French on the menu unless you are in the heartland (中心地带) of French Canada. However, all products sold in Canada must, by law, have labels (标签) and instructions in both languages.
In Canada’s English speaking provinces, official bilingualism (双语) means that students can choose to complete a special French language course. Under this program, they are taught most of their subjects in French.
If a student begins the course in kindergarten (幼儿园) or Grade One, it is likely that all their lessons will be in French. However, if they start at junior high school, 25 percent of the teaching will continue to be in English.How many provinces are there in Canada?
| A．Ten. | B．Nine. | C．Eleven. | D．Two. |
Which country controlled Canada before its independence?

| B．In Quebec and a few other places. |
| C．From the two national television networks. |
| D．All over Canada |
What do we know about the education in Canada?

| B．If you choose a special French language course, most of the subjects are taught in French. |
| C．The courses in primary school are all taught in English. |
| D．Most of the courses in junior high schools are taught in English. |
Shane Thomas is a 10-year-old pianist from England. He’s being called the next Mozart because of his amazing abilities.
He has only been having piano lessons for four months, and practices four hours a week, but he has already played difficult classical pieces. He was just seven when he sat down at the piano, and could play at once. He also says he never gets nervous.
When Shane was three years old, he said that he could play the piano, but nobody took him seriously. At school, he could listen to the teacher and do his work while composing (作曲) in his head. Shame remembers all the melodies（旋律）,and when he gets home he plays them on the piano, while his father records them. Shane loves playing the piano, and when he grows up he wants to be a composer.
His tutor, Richard Goffin-Lecar, says he is like Amadeus Mozart, who lived during the 18th century in Salzburg, Austria, and was one of the most famous composers ever. Mr. Goffin-lecar says, “I don’t teach Shane very much. I just give him directions, then sit back and watch.”
His father, a single parent with two other children, says that although he has little money, he wants to send Shane to a good music school. “I’m a single father, but I have this gifted child.

Mexico City is truly one of the most amazing cities in the world with a mixture of both the old and new world. From the moment your plane starts to descend into this vast city, you know that your trip will be quite an adventure.
Once in your taxi and the moment you leave the airport, you are amazed at the large amount of slow traffic. The volume of the traffic can be stressful to some.
The "Paseo de la Reforma(改革大道)", running southwest across the city, is one of the major tourist and business areas in Mexico City with many high quality hotels only walking distance from great restaurants and other tourist attractions. The only problem you will have is trying to see all of these sites during your vacation time.
One of the most popular attractions in this area is the National Museum of Anthropology along the northwest part of the street. There are thousands of artifacts on display showing the history of the area and numerous items found from the many Aztec sites in the area. Walking southwest from the museum, you will soon reach the Mexico City Zoo, which is a great place to spend an afternoon.
Across the street from the museum is the Chapultepec Castle, once an important site in the Mexican-American war. It's also a good idea to take the train up the hill to where the castle is located as the hill is steep. It's important to keep in mind that Mexico City is over 7,000 feet above sea level and some feel it difficult to breathe when walking.
You can take a taxi to the Coyoacan market during the evening on a weekend. It's a great place to get some cheap souvenirs to bring back home and to enjoy some traditional Mexican cuisine. However, you must be careful where you eat and that the meat is well cooked.The tourists in Mexico City may not be satisfied with______.

Beginning in October, more than 13,000 McDonald’s (麦当劳)restaurants in America will use a new variety of cooking oil. McDonald’ s aims to make its French fries (油炸食品) and other fried foods healthier.
The change will not affect the taste or the number of calories in the food. But by changing the cooking oil, McDonald’s says, it hopes to cut by nearly half the amount of trans fatty acids (转换脂肪酸) in French fries and reduce the amount of saturated fats(饱和脂肪) by 16 percent. Scientists believe that trans fatty acids and saturated fats raise cholesterol(胆固醇) levels and increase the risk of heart disease.
McDonald’s new step is important because McDonald’s is an industry leader and other fast-food chains and food processors may follow the lead.
For McDonald’s ,the action comes at a time when Americans are becoming more and more concerned about; obesity (肥胖) and are increasing pressure on food companies to offer healthy and nutritious (有营养的) food to consumers.
After three years of study, McDonald’s officials say they are switching oil that is lower in saturated fats and trans fatty acids. McDonald’s says the change will not cause higher price for consumers.
Though there is some change, scientists say that the amount of trans fat in foods at McDonald’s and at other fast-food companies is still important.More than 13,000 McDonald’s restaurants in America will use a new kind of cooking oil to ______________.
| A．lower the costs of the products |
| B．maker its food taste hatter than ever before |
| C．cure (治愈) the heart disease |
| D．do good to the health of consumers |
The underlined ward "switching" here has the same meaning as " _______".
| A．turning on | B．turning off | C．changing | D．studying |
The main idea of the passage is __________.
| A．McDonald’s is a pioneer in food products |
| B．McDonald’s is enlarging its restaurants in the world |
| C．fried foods can’t keep up with the development of modem society |
| D．McDonald’s is to use new cooking oil |
When a new kind of cooking oil is used in McDonald’s, ________
| A．the prices of McDonald’s foods will be a tot higher |
| B．consumers will find the taste of McDonald’s foods different |
| C．many other food companies will do what McDonald’s does |
