Read the following passage and then answer the questions.

    When thinking back to an experience that has affected me the most, I can't help but recall the first time I performed for a crowd with my band.

    As I stood in the dark, in front of 300 people, my head began to pound and my eyes began to hurt from straining to see the faces before me. No matter how many times I wiped off my hands, they were covered with sweat, making them fumble across the strings of my guitar. Then, in a flash, the spotlights were turned on and the crowd yelled. My heart raced and I knew that the night of my first concert would be exciting and memorable.

    The concert was held annually at Frank's school. Being the largest activity for the students in the spring, we were told to expect the whole school to come to see us play. That fact went over and over in my mind. True, I had played in the school band in concerts for many people, but that was with a large group and I had sat in the back. Here it was just the three of us, all up front. I had had different visions of what performing would be like, but what ended up happening was a pleasant surprise.

    During the first song, the crowd stood in a mixed state of confusion and excitement. I could see nothing but their dark shapes, some swaying to the beat of the bass drum, others standing still, examining our every move. The song ended with hesitant applause.

    Glancing at Frank, the guitarist and singer, I read a message in his eyes. "I don't think they like us." His look pierced through my heart and I almost left the stage, yet kept going anyway. The second and third songs went the same way with the crowd looking at us like monkeys in a zoo. But then the magic started.

    Our fourth song we had was written for the occasion and it was as if it were the beginning of a trip that we would take with the crowd of onlookers. The funk bass and driving drums seemed to pick these people up like puppets and do with them what they pleased. The crowd danced and jumped and clapped, in and out of beat. Our music was giving these people a reason to lose their inhibitions and for a short time, enjoy themselves. By the end of the second to last song the crowd was at our mercy. Finally creating a situation that I had only dreamed of, during the last song the crowd began to sing the words. But it was not just any song, it was a song we had written. This sent my heart racing and I couldn't help smiling and even laughing. The song ended and an echoing roar came over the crowd.

    The concert was to me part of a childhood dream. My friends and I were responsible for giving 300 people a good time for an evening. They sang my words and they hummed my tune, and all helped to make the dream come true. That night back in my room, I sat up all night. I saw the bodies dancing in front of me and heard their screams. Even though I may perform in college and in the future, this feeling is one I may never feel again.

    Something happens to many children when they are out of school over the summer months. It is called the “summer slide.” This may sound like a ride at a water park. But it's not. Summer slide is when children forget much of what they learned during the latest school year.

    To fight the effects of summer slide, teachers often give students homework over the summer. Many parents may send children to all kinds of camps or find other activities to keep them learning. Some even try to build up their children's strengths by getting them into extra tutoring.

    However, experts say keeping children busy all the time is not good for them. The result is often a tired child with an overcrowded schedule. This keeps a child's brain active constantly—learning, gathering information and preparing for the next event. And this may have the opposite effect the parents are not hoping for.

    What should parents do instead? Nothing. According to Lea Waters, a psychologist specializing in positive psychology and positive education, slowing down actually helps children become the best they can be. Machines need to be reset, while kids need to goof off（偷懒）. She says that goofing off really allows kids to have some downtime, when they're not focused on a specific task but are free to do something that they're interested in doing and that they can do more automatically and get enjoyment from, like shooting baskets or listening to the music.

    She also adds that goofing off does not mean the brain isn't working. It just goes into this default network mode（默认网络模式）and uses that time to process all the information it had during the day, to integrate（整合）new information. It makes a kind of decision about what information to put into memory and what to get rid of, which in fact helps to improve memory.

    Theme park getaways are popular with families, but they sure aren't cheap. Happily, there are some golden rules of ticket-buying that apply to pretty much every theme park, and they can help you chip away at the cost of tickets. {#blank#}1{#/blank#}

    Buy tickets online.

    Never ever pay the walk-up ticket price at a theme park. {#blank#}2{#/blank#} You're guaranteed to save a significant sum-sometimes as much as $ 20 per ticket-even for same-day tickets.

    Buy in advance.

    {#blank#}3{#/blank#} For instance, Knott's Berry Farm in Buena Park, California, slices off $25 per ticket when you make your purchase at least three days ahead.

     {#blank#}4{#/blank#}

    This one is a universal no-brainer. Single-day ticket prices at Cedar Point in Sandusky, Ohio, are about 30 percent less than admission on Saturdays and Sundays. But the big bonus is that lines will be much shorter, allowing you to spend less time waiting in lines and more time having fun.

    Go in the afternoon.

    {#blank#}5{#/blank#} For example, Hersheypark's sunset tickets allow entry after 4 pm or 5 pm, depending on the day. You'll still get between four to six hours of fun before the park closes, and you'll pay up to 50 percent less than the full-day ticket price.

A. Avoid weekends.

B. Buy more tickets than you need.

C. Here are some ways to lower your theme park spending.

D. At larger parks, you'll save money when you buy a package.

E. Instead, visit the theme park website and print out your tickets before you go.

F. Some parks offer deeply discounted tickets for visitors arriving later in the day.

G. Most theme parks offer a price cut if you buy tickets at least a few days before you arrive.

    Asthma(哮喘) is a long-lasting breathing disease that affects millions of Americans, many of whom are children. People who get asthma will suffer from lack of breath, difficulty in breathing or coughing--which are caused by the tightening of the muscles in airways. Untreated asthma can lead to poor lung function and death, but asthma can also be effectively controlled with proper treatments.

    Research is discovering genes that contribute to the development of asthma. This development has pointed researchers to the role of indoor and outdoor pollution as environmental factors that contribute to the increased occurrence of asthma.

    The Indoor Pollution

    Indoor pollution has increased with the developments in building materials and in heating and air conditioning systems. In addition to poisonous gases that come from paint, other materials like dust and perfumes used in household products such as washing powder are recycled continuously through the house, winter and summer.

Unlike the days before central heating or before whole-house air conditioning, these materials and chemicals cannot get out of modern homes. Most  often, they cause breathing  problems in the members of the family with the least-developed autoimmune(自身免疫的) systems. Proper venting (通风) and use of environmentally-friendly building materials and carpeting can help reduce the presence of these chemicals.

    The Outdoor pollution

    Researchers have also established outdoor pollution's role as a probable cause of asthma. Asthma has been proven to result from some fuel products. Smog and the small matters carried by it have been recognized as a factor which leads to asthma since the 19th century when London saw more and more diseases in the industrial population. Industrial pollutants and other chemicals which are produced in water treatment and open treated water like that found in the swimming pools also contribute to increased cases of asthma as well as other illnesses.

    Those most affected by the increase of industrial and environmental pollution are children. Although much has been done to control the levels of pollution in the US, there still remains much to do as it is a worldwide phenomenon. Until an international effort can be made to limit carbon emissions, the occurrence of environmental asthma will probably continue to increase.

The North Star

    Among the pile of stars in the universe, there are a couple that are of great importance to people on Earth. The sun, of course, is one of them. The other is known as Polaris, the North Star. {#blank#}1{#/blank#} Therefore, it is a great compass(指南针).When people in the northern part of Earth look toward Polaris, they can be certain that they are facing north. The permanence of Polaris in the north sky has helped countless people find their destinations.

    Before the invention of modern navigation tools, sailors relied on Polaris. From the top of their ships, sailors would look for Polaris to figure out their place at sea. They figured out the angle between the star and the horizon to determine their latitude(纬度). As long as the equations were not wrong, the results were very reliable. Polaris also let sailors determine North, South, East, and West. {#blank#}2{#/blank#}

    To those who sail at night, changeable storms and dark clouds were more than annoying things.{#blank#}3{#/blank#} It's possible for a captain to make an accidental wrong turn. The ship could become stranded at sea, and the frustrated captain would have no way to get the ship back on the right course. The sailor's fears wouldn't be relieved until the clouds cleared and Polaris came back into view. Even today, sailors sometimes choose to steer by using Polaris on clear nights.

    {#blank#}4{#/blank#} The Big Dipper, a constellation that is well known in astrology, appears to revolve around Polaris. The handle of the Big Dipper always points to the North Star. When people get lost, it's comforting to know that their problems can be relieved by looking at the sky.

A. It's not difficult to tell the Polaris apart from the pile of other stars in the universe.

B. People who are lost can be relieved by gazing up at Polaris.

C. By knowing directions and their location, sailors could easily steer their ships.

D. They could destroy entire journeys by blocking the view of Polaris.

E. It's certain that the Polaris is part of a constellation(星座), which is not far from it.

F. It is special because it is the only star that always appears to be in the same place in the sky.

Study in Canada

    Why Canada?

    Canadians place a premium(保险) on education and demand first-rate schools. Canada is among the top three countries in the Organization for Economic. International students who graduate from Canadian universities land successful and promising careers.

    Ranked as #1 in the World

    For the past several years, a United Nations survey has found Canada to be the best place in the world to live in. Conducted every year, the survey evaluates quality of life in 174 countries, using over 200 performance indicators. Canada earned particularly high marks for its access to education, high life expectancy(长寿), and low crime and violence rates.

    Canadian Education is Competitively Priced

    Tuition fees for international students in Canada are comparatively much lower than in any other English speaking country

    More than 800000 Canadians trace their roots back to India!

    High Standard of Living

    Canadians enjoy a standard of living among the highest in the world. More than 65 per cent of Canadians own their own homes, with a higher percentage owning durable goods. Canadians are proud of their world-famous and highly advanced broadcasting system which includes more than 1,000 AM and FM radio stations and some 719 television stations to serve, entertain and educate the listening and viewing audience.

    The vast majority of Canada's population of more than 30 million people lives in urban areas.

    Welcoming & Beautiful Environment

    All major urban centers have a variety of shopping malls, restaurants, theaters, art galleries and museums. Canadian cities provide numerous parks, gardens and beaches for public use, as well as excellent sports and recreation facilities. Canadians place a high value on their natural environment.

    Canada is well-known as a safe, just and peaceful society. Canadian crime rates have been falling steadily since the 1990s. In 1997, Canada's police-reported crime rate decreased for the sixth year in a row, falling by five per cent. Violent crimes declined for the fifth year in a row in 1997 and Canada's homicide (杀人) rate now accounts for less than one percent of all reported violent incidents. Unlike its US neighbors to the south, firearms are strictly controlled and generally are not permitted in Canada.

    Canada is a country with two official languages, English and French. The vast majority (75 per cent) of Canada's French-speaking inhabitants(居民) live in Québec(魁北克), which is located in the eastern part of the country but there are French-speaking communities throughout  the country.

    Internationally, it is estimated that more than 800 million people speak English and 250 million speak French. Canada offers superior English as a Second Language (ESL) and French as Second Language (FSL) training for students wishing to learn either or both languages.
