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.

6 . 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. |

7 . 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.

Woolworth realized he had a natural skill for showing goods to attract people’s interest, but he soon learned something more important. One day his boss told him to sell some odds and ends(小商品)for as much as he could get. Frank put all these things on one table with a sign which said “FIVE CENTS EACH’. People fought and pushed to buy the things and the table was soon cleared.
Soon afterwards, Woolworth opened his own store, selling goods at five and ten cents. But he had another lesson to learn before he became successful. That is, if you want to make money by selling low-price goods, you have to buy them in large quantities directly from the factories. Once, for example, Woolworth went to Germany and placed an order for knives. The order was so large that the factory had to keep running 24 hours a day for a whole year. In this way, the price of the knives was cut down by half.
By 1919, Woolworth had over 1000 stores in the US and Canada, and opened his first store in London. He made many millions and his name became famous throughout the world. He always ran his business according to strict rules, of which the most important was : ‘THE CUSTOMER IS ALWAYS RIGHT.”
