Just like children, baby animals spend countless hours at play. After studying animal play for many years, scientists recognize that young animal play is practice for adult behavior. Today this play is roughly divided into the following groups.
Locomotor play refers to the movements animals carry out in their play. Running, leaping, turning, and kicking are some of the most common examples of locomotor play. An adult deer may run, leap, and twist(曲折前进) to escape its attackers. Play movements like these surely make young animals nimble. Someday these skills might help save their lives.
Moving forward slowly, attacking suddenly .and biting are examples of predatory play that help young predators(食肉动物) prepare for a life of running after and taking hold of other animals. Wild cats, wolves, and bears are predators. It is very common to see these young animals play this kind of games which sharpen their skills and teach them about their strengths and limitations.
For children, playing with toys is both fun and educational. It helps improve their hand and eye movements as well as develop hand skills to accomplish tasks. It is the same with animals. Young chimpanzees improve their hand skills while playing with sticks. Birds also play with things in ways that teach. Swallows drop and recover feathers in mid air. Diving suddenly to catch the feathers is good practice for catching flying insects.
Social play helps animals learn how to behave when they run into other animals. And it teaches animals about communication. An animal gives signals to let another animal know it wants to play. Many animals give signals by showing a " play face" . In some ways this face is like a human smile; the animal holds its mouth in a relaxed and open manner. During play-fights, some animals may step backwards to signal that they are playing and not acting seriously.
Until now, scientists have understood playful acts help prepare animals for their serious adult situations. But the numbers of playful species and examples of animal play are vast. The purpose of animal play may have meanings scientists have not discovered yet.The main purpose of the text is to ______.

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?

Where can you watch French television programs?

| 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.

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 __________.
