Getting less sleep has become a bad habit for most American kids. According to a new survey(调查) by the National Sleep Foundation, 51% of kids aged 10 to 18 go to bed at 10 pm or later on school nights, even though they have to get up early. Last year the Foundation reported that nearly 60% of 7- to 12-year-olds said they felt tired during the day, and 15% said they had fallen asleep at school.
How much sleep you need depends a lot on your age. Babies need a lot of rest: most of them sleep about 18 hours a day! Adults need about eight hours. For most school-age children, ten hours is ideal(理想的). But the new National Sleep Foundation survey found that 35% of 10- to 12-year-olds get only seven or eight hours. And guess what almost half of the surveyed kids said they do before bedtime? Watch TV.
“More children are going to bed with TVs on, and there are more opportunities(机会) to stay awake, with more homework, the Internet and the phone,” says Dr. Mary Carskadon, a sleep researcher at Brown University Medical School. She says these activities at bedtime can get kids all excited and make it hard for them to calm down and sleep. Other experts say part of the problem is chemical. Changing levels of body chemicals called hormones not only make teenagers’ bodies develop adult characteristics, but also make it hard for teenagers to fall asleep before 11 pm.
Because sleepiness is such a problem for teenagers, some school districts have decided to start high school classes later than they used to. Three years ago, schools in Edina, Minnesota, changed the start time from 7:25 am to 8:30 am. Students, parents and teachers are pleased with the results.
1.What is the new National Sleep Foundation survey on?
A.American kids’ sleeping habits. B.Teenagers’ sleep-related diseases.

2.How many hours of sleep do 11-year-olds need every day?
A.7 hours. B.8 hours.
C.10 hours. D.18 hours.
3.Why do teenagers go to sleep late according to Carskadon?

B.They tend to do things that excite them.
C.They follow their parents’ examples.
D.They don’t need to go to school early.

It has become a habit for many of us. When you're tired of online shopping, you head to the bathroom to do your best makeup for the perfect selfie(自拍)for Facebook, Instagram, Snapchat or all of the above. When you're ready, you hold up your phone and, in an instant, snap(拍照)。
But have you ever wondered what's behind your burning desire to self-document?Most people would say that this is a way to express themselves and perhaps make them become more confident of themselves. But the moment you upload that picture, it's no longer yours to judge. Instead, you pass on that power to the online world.
While you may think that your growing collection of selfies attracts people, quite the opposite may be true. A recent study was conducted on a total of 238 people in Austria, Germany and Switzerland. 77%of the people surveyed admitted to regularly taking selfies. Interestingly, 82% of people said that they would rather see fewer selfies on social media. In other words, we like taking selfies but seriously dislike looking at other people's selfies online.
This research finds that there is a big difference between how we see our own selfies and how we judge other people's pictures. It suggests that we are comfortable with the selfies we post since we believe they are obviously not serious or vain, but we think everyone else is an egoist(自我主义者)for doing the very same thing. After all, we are able to separate our own selfies from the sea of them online and naturally think that ours are the only authentic ones.
So, the next time you reach for your phone and take a selfie picture, consider this: The people around you may not need another carefully planned snap of your face. Instead, you might be better off, giving it a break and calling off the selfie photo today. While you're at it, make sure you never post these pictures on social media either.

B.They envy our life after appreciating them.
C.They are likely unwilling to see them online.
D.They hardly make annoying reviews on them.
3.Why do we regard others as egoists for taking selfies?
A.They are not serious but vain in nature.
B.We don't think their selfies are authentic.
C.We are too proud to acknowledge others.

American college students are becoming more adventuresome as they study abroad, showing less interests in English-speaking destinations such as Great Britain and Australia and more in such countries as China, India, Argentina and Brazil.
Britain remained the most popular study destination in 2005, according to annual figures from the Institute of International Education, followed by Italy, Spain and France. But the number of American students studying in Britain and Australia descended a little, even as the number of American students abroad rose by 8%. The growth came in non-English speaking European countries and in Asia. China is now the eighth most popular destination for American students, attracting nearly 6,400 in 2005, up 35% from the number of the year before. Argentina and India saw increases of more than 50%.
Allan Goodman, president of the Institute of International Education, said that a range of factors contributed to the trend, from growing awareness of globalization after the terrorist attacks on September 11, 2001, to programs such as former President Bush’s National Security Language Initiative, which trains soldiers, intelligence officers and diplomats in foreign languages. “What Americans are doing is waking up and discovering there’s a world out there,” he said.
Other figures showed the flow of students in the opposite direction, from foreign countries into American universities. The institute found that international enrollment (入学) in American higher education remained steady at about 565,000. The figures are of keen interest to universities, which depend on foreign students for teaching and research help, and to policy-makers, who consider it important, as future foreign leaders may be familiar with the United States. The year of 2005 saw big increases in students from South Korea, Mexico and Taiwan of China. India sends the most students and China is No.2. Other countries that show large percentage increases in the number of students sent to the US include Nepal and Vietnam, while Japan, Turkey and Malaysia saw declines. About 58% of international students in the US come from Asia.
1.What does the underlined word “descended” in Paragraph 2 means?
A. Changed. B. Declined. C. Multiplied. D. Increased.
2.Why do more American students study in Asia?
A. They expect to get more teaching and research help.
B. They lose confidence in English-speaking countries.
C. They are afraid that terrorist attacks will happen again.
D. They prefer to explore a different world from their own.
3.Where were most foreign students in America from in 2005?
A. China. B. India. C. Argentina. D. Britain.
4.What can we infer from the passage?
A. There were 6,400 American students studying in China in 2005.
B. Chinese students to America will overpass Indians in the future.
C. International enrollment in American higher education changed a lot.
D. Asian students account for a large part of foreign students in America.
