1 . If you’ve ever had trouble getting your teen up in the morning or you’ve seen your teen fall asleep during the school day, you’re not alone. Many teens have difficulty in waking up early for school, and that’s because they sleep late at night.

The American Academy of Pediatrics’ Adolescent Sleep Working Group reviewed studies about sleep in teens. Researchers studied the harmful effects of not getting enough sleep-anything less than 8.5 to 9 hours of sleep on school nights-could have on young people. They discovered not getting enough sleep may cause poor grades at school. Not getting enough sleep has also been connected to a higher risk of car accidents in teens.

It may seem as though the way to solve the problem would be for teens to just go to sleep earlier. But researchers say that isn’t likely to work. Teens experience physical changes that make falling asleep earlier difficult. Their biological (生物的) clocks just won't allow them to fall asleep at 8 p.m., even when they’re tired.

Studies have shown that just delaying (推迟) school by 30 minutes can have a great effect on a teen's health and performance. So most researchers suggest the school start time be delayed until at least 8:30 a.m. for teenagers.

Some of the benefits could include:

·Teens may be more likely to get the necessary amount of sleep.

·The delayed start time could help teens sleep during their natural sleep.

·Teens may be less likely to depend on coffee to stay awake during the day.

·Enough sleep could help teens study better in class, which could help them do better in exams.

·Sleeping longer could reduce health problems caused by a lack of sleep in the long run.

·Getting home later in the afternoon may reduce the amount of time when some teens are home alone, and could reduce the possibility that tens will take part in unhealthy activities.

But doing that can also cause some problems.

2 . Running is a very popular sport. Millions of people run because they enjoy it or want to be in good physical shape. A runner does not need special skills or equipment.    1    .

Daily running improves a person's physical condition. It helps oxygen circulate (循环) through your body and makes your heart and leg muscles stronger.    2    .What's more, running helps you control your weight because when you run, you burn up the fat in your body.   

Many runners like taking part in long distance races like marathons (马拉松).     3    .They are held in many cities all over the world. For a good runner, taking part in a famous marathon is an honour of a running career.

There are no official world records in marathon races because courses are different all over the world.     4    . However, sometimes a course may be hilly with lots of ups and downs. Bad weather with a lot of wind and rain also makes it more difficult for runners to achieve good results.

    5    .Don't start to fast, or you will become tired very quickly and can't continue. This is called "hitting the wall". In most cases, runners then give up completely. On the other hand, you shouldn't start too slowly, or you won't reach the time limit you want to achieve.

A．He needs to be well-prepared and train a lot.

B．Marathons are the most popular running events.

C．During a marathon, you should keep a right pace.

D．Sometimes the raceway is flat and runners run faster.

G．It also helps you fight off stress after a tiring day in school or at work.

3 . Most young architects particularly those in big cities— can only dream about working in a building of their own. And making that dream come true often means finding a building no one else seems to want, which is exactly what happened to David Yocum and his partner, Brain Bell. Their building is a former automobile electrical-parts film in Atlanta. From the outside, it looks too old, even something horrible, but open the door and you are in a wide, open courtyard, lined on three sides with rusting (生锈的) walls.

In 2000, Yocum and Bell found this building in the city’s West End. Built in 1947, the structure had been abandoned years earlier and the roof of the main building had fallen down. But the price was right, so Yocum bought it. He spent eight months of his off-hours on demolition (排除), pulling rubbish out through the roof, because it was too dangerous to go inside the building. The demolition was hard work, but it gave him time to think about what he wanted to do, and “to treasure what was there — the walls, the rust, and the light.” Yocum said. “Every season, more paint falls off the walls and more rust develops. It’s like an art installation (装置) in there—a slow-motion show.”

Since the back building had been constructed without windows, an all-glass front was added to the building to give it a view of the courtyard, and skylights were installed in the roof. The back of the building is a working area and a living room for Yocum and his wife. A sort of buffer(缓冲） zone between the front and the back contains a bathroom, a kitchen and a mechanical room, and the walls that separate these zones have openings that allow views through to the front of the studio and the courtyard beyond.

Yocum and Bell, who have just completed an art gallery for the city, feel that the experience from the decoration of their building, focusing on the inside rather than the outside, has influenced their work. It has also given these architects a chance to show how they can make more out of less.

1. According to the passage, it is ________ for most young architects in big cities to work in a building of their own.

A．easy	B．unnecessary
C．unrealistic	D．common

2. Yocum bought the old building because ________.

4. It can be inferred from the passage that Yocum and Bell ________.

A．benefited a lot from pulling down the roof

B．turned more old buildings into art galleries

4 . Puppy Food

A puppy (young dog) is a precious addition to any family. The excitement of bringing home a little furry friend will always live in our memories. Like all of us, though, your puppy must have adequate nutrition right from the start to make certain that it'll have a long and healthy life.

    1     You might ask yourself what is the best for your new pet with all of the different varieties on the market in all of their attractive packaging. Some dry food produced specially for puppies is the best for the development of their teeth.     2    

Contrary to the belief of many first-time puppy owners, it is not always the best idea to purchase food that is too high in calcium(钙), protein, and vitamin levels.    3     In addition, a high intake of calcium is associated with bone disease in large-breed dogs. If you have a "small-breed" puppy, you can buy that kind of food.

It is not a good idea to feed the food you eat to your puppy frequently, as your puppy may become selective about food.    4     Some people think that dog biscuits and other treats are fine, but they should not be a main part of puppy's diet.

Young puppies should be fed three times a day. Each puppy is unique, however, so feeding them twice a day is acceptable. After ten to twelve weeks of age, feed your puppy twice per day. Allow your puppy to eat as much as he would like in fifteen minutes.    5     If you let your puppy eat too much or too often by keeping food accessible at all times, he may become overweight and have health problems as an adult. Like humans, your puppy will not enjoy the food any longer if it is there at all times.

A．Pick up the dish with the remaining food.

B．Proper food is a basic necessity for your puppies.

C．Remember to give your puppy the food he would like to have.

D．It can also cause an upset stomach due to an unbalanced diet.

E．A further benefit is that it is less expensive than the canned food.

F．One example is that extra helpings of nutrients do harm to digestive organs.

G．It's good to provide the extra nutrients a puppy needs until he grows larger.

5 . The weather is getting hotter. You are thirsty playing basketball or riding home from school. A cold drink may be just the thing. But be careful what you are drinking. Something that looks cool may not be good for your health.

There are plenty of "energy drinks" on the market. Most of them have beautiful colors and cool names. The lists on them tell you they are helpful to your health. Sounds great!

But after a careful check you may find that most energy drinks have lots of caffeine(咖啡因) in them. These drinks are especially aimed at young people, students, busy people and sports players. Makers sometimes say their drinks make you better at sports and can keep you awake. But be careful not to drink too much.

Caffeine makes your heart beat fast. Because of this, the International Olympic Committee has limited(限制) its use. Caffeine in most energy drinks is at least as strong as that in a cup of coffee or tea. Possible health dangers have something to do with energy drinks. Just one box of energy drink can make you nervous, have difficulty sleeping and can even cause heart problems. Scientists say that teenagers should be discouraged from taking drinks with a lot of caffeine in them.

6 . My favourite book is The Adventure of Tom Sawyer by Mark Twain. Tom lives with his aunt Polly in a quiet street of St. Petersburg, Missouri. He’s a lively and clever young boy, and he finds himself in many exciting adventures. He runs away with his two friends, Huck Finn and Joe, to an island in the middle of the Mississippi River for several days. With Huck he goes looking for treasure, with Becky he gets lost in a cave. And finally, they find a box of gold.

My favourite scene in the book is when everyone thinks Tom is dead. He decides to go to his own funeral. He hides and watches for a time and then suddenly he appears. Everyone is astonished to see him but they’re also pleased to see him alive.

Tom is the hero of the story, but there are other important characters. Huck is an outsider and everyone is afraid of him. Becky is pretty with fair hair, Joe is Tom’s best friend. And Injun Joe is the bad man of the story.

The theme of the story is about children growing up. It describes how strangers are seen in small towns of America. Finally, it talks about freedom, social rules and how people are punished for bad behaviour.

Why do I think The Adventure of Tom Sawyer is a great book? Mark Twain wrote the story in 1876, but it’s still read and loved by people all over the world today. And although it’s only a story, Twain wrote it in the everyday English of the southern states of America in the 19th century, so it sounds very real. Today it’s thought to be one of the greatest books in American literature. Go on—read it! I know you’ll enjoy it, too.

7 . LANGUAGES Canada,a new Canadian national organization of public and private language training programs,was started recently to ensure that language training in Canada is of high quality,Canada News Wire has reported.

Canada has developed its language-training programs for over forty years without a comparatively uniform(adj. 一致的；相同的) quality standard before Languages Canada adopted(采用) a complete system of rigorous standards that apply equally to all public and private schools in Canada To qualify(取得资格；具备合格条件),a school is evaluated in a number of categories including curriculum,teacher qualifications,student services,student admissions,marketing,promotion,facilities and administration.

8 . Talk about a real-life hero! Ten-year-old Larry Champagne from St. Louis, Missouri, hit the brake (刹车) on a runaway school bus. He saved himself and 20 other kids on board from disaster.

It all happened in one terrible accident. On the way to school, the bus driver, Ernestine Blackman, suddenly fell ill. Seeing the car was running away, the other kids started to scream, but Larry ran to the front and stopped the bus.

“At first I thought, ‘We’re going to die,’” says Larry, “but after I pressed the brake, I felt safe.”

Larry’s speedy reaction made news all over the country. He appeared on TV shows as a hero. The bus company gave Larry a big gift. His school hung a medal of honor around his neck.

“My grandmother always tells me to do what’s right,” says Larry. He thanked his brother, Jerrick, 9, who “helped me get the bus driver up” during the emergency（紧急情况）. How did he know how to stop the bus? Larry is something of a mechanic（机械师）. He helps his grandfather work on his old truck. “He gets his hands dirty,” says his grandfather.

9 . America is a mobile society. Friendships between Americans can be close and real, yet disappear soon if situations change. Neither side feels hurt by this. Both may exchange Christmas greetings for a year or two, perhaps a few letters for a while, then no more. If the same two people meet again by chance, even years later, they pick up the friendship. This can be quite difficult for us Chinese to understand, because friendships between us flower more slowly but then may become lifelong feelings, extending(延伸) sometimes deeply into both families.

Americans are ready to receive us foreigners at their homes, share their holidays, and their home life. They will enjoy welcoming us and be pleased if we accept their hospitality(好客) easily.

Another difficult point for us Chinese to understand Americans is that although they include us warmly in their personal everyday lives, they don't show their politeness to us if it requires a great deal of time. This is usually the opposite of the practice in our country where we may be generous with our time. Sometimes, we, as hosts, will appear at airports even in the middle of the night to meet a friend. We may take days off to act as guides to our foreign friends. The Americans, however, express their welcome usually at homes, but truly can not manage the time to do a great deal with a visitor outside their routine. They will probably expect us to get ourselves from the airport to our own hotel by bus. And they expect that we will phone them from there. Once we arrive at their homes, the welcome will be full, warm and real. We will find ourselves treated hospitably.

For the Americans, it is often considered more friendly to invite a friend to their homes than to go to restaurants, except for purely business matters. So accept their hospitality at home.

1. Which of the following statements is TRUE according to the passage?

A．Friendships between Americans usually extend deeply into their families.

B．Friendships between Americans usually last for all their lives.

C．Americans always show their warmth even if they are very busy.

2. From the last two paragraphs we can learn that when we arrive in America to visit an American friend, we will probably be                 .

A．warmly welcomed at the airport

B．treated hospitably at his home

C．offered a ride to his home

D．treated to dinner in a restaurant

3. The underlined words “generous with our time” in Paragraph 3 probably mean                  .

A．willing to spend time	B．serious with time
C．careful with time	D．strict with time

4. A suitable title for this passage would probably be “                ”.

A．Friendships Between Chinese

B．Friendships Between Americans

C．Americans' and Chinese's Views of Friendships

D．Americans' Hospitality

10 . College is a lifetime investment(投资)—the gift of a college education can open the door to a world of opportunity for your child or grandchild. Savings(储蓄), even not so many at a time, can make a big difference.

With the cost of a college education continuing to rise, the key is to start saving early and regularly. By saving a set(固定的) amount at set times, your money can grow as your child does. According to the College Board, the average cost for four-year public colleges has increased by nearly 51% over the last 10 years and these costs will almost certainly continue to rise. Saving for college can help with the increasing cost of a college education and help you be well prepared when your child is ready for college.

Saving for your child's college education is an investment in their future. The savings you make today will pay off in increased earnings(收入) in the future. According to the U.S. Census Bureau, college graduates earn an average of $1 million more than high school graduates during their careers. The value of your investment in a college education will continue to grow for a lifetime.

Set your college saving goals realistically(现实地). You may not be able to save enough for all four years' fees, but you could save enough to give your child the right start.

More and more families depend on student loans(贷款) to pay for college. By saving for college, families will have less burden of paying off loans and help their children leave school without worrying about paying off loans.

1. From the second paragraph we can learn that                 .

A．the College Board increased public college costs
