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?

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?
A. They are affected by certain body chemicals.

One in every five young people has a sleep problem, so you’re not alone. Getting enough sleep has become as important as eating vegetables and exercising regularly. It’s very important for your body. Most young people only get seven hours of sleep each night, when they actually need nine hours. And making up for lost sleep during the week by sleeping on weekends. It doesn’t really work. In fact, sleeping late on weekends may actually do you more harm that good, if you have sleep problems.

DO something relaxing before going to bed.
EXERCISE during the day. Don’t exercise right before going to bed.
AVOID drinking alcohol. Alcohol makes you excited. This prevents you from falling asleep or wakes you up during the night.

Getting up early has been regarded as a good habit since ancient times. Many years ago, people thought that if we went to bed early and got up early, we would be energetic the whole day. So, getting up early is of great importance to us all.
In fact, morning is the best time of a day. In the morning, the air is the freshest and people are usually in the best conditions. Many of us may have the experiences that we memorize some things more quickly and accurately in the morning than at any other time of the day.
Additionally, if we get up early and do some morning exercise or only take a short walk in the morning, without doubt we can build our bodies and become much healthier. That is why many people getting up early do physical exercise year after year.
We will also have enough time to make a plan and get ready for our work or study of the day if we get up early. For example, if everyone in the family gets up early, we will have enough time to prepare the breakfast for the whole family. Children will have enough time to catch the school bus, and husband will never forget to change his dirty shirt. Everything is in order. What a harmonious scene! However, if we get up late, we will probably have to do everything in a great hurry, making it in a mess.
Let us remember getting up early is a good habit. If you are a late riser, you may find it difficult to form the habit of getting up early. You will have to make efforts to do so. If you want to get up early, sleeping earlier the night before expect to be successful. Besides, you can set your alarm clock or ask someone whom you know will be awake at that time to call you. If you stick to getting up early every day, you will certainly benefit a lot from it.

A new study has found that North American migratory(迁徏的) birds have been getting smaller over the past 40 years. Researchers say the finding suggests a warming climate(气候)could be affecting bird growth in North America -- and across the world.
The study was recently published in Ecology Letters. Researchers measured(测量)the size of 80,000 birds killed from 1978 to 2016 during the spring and fall migrations in the city of Chicago, Illinois. Over the 40-year period, body size decreased in all 52 species. The average body weight fell by 2.6 percent. Leg bone length dropped by 2.4 percent. The one area of growth was the wingspan, which increased by 1.3 percent.
The researchers said the wing growth likely happened to allow the birds to continue making long migrations with smaller bodies. The study considered a principle known as Bergmann’s rule, in which individuals within a species grow smaller in warmer areas and grow larger in colder ones.
Brian Weeks, a biologist at the University of Michigan’s School for Environment and Sustainability, helped lead the research. He said that he believes the results show a clear connection between a warming climate and the growth of the birds. “In other words, climate change seems to be changing both the size and shape of these species,” he said.
The study found a direct connection between the average summer temperature and the body size of the birds. Dave Willard works with Chicago’s Field Museum, which was in charge of measuring all the birds. He said nearly “everyone agrees that the climate is warming, but examples of just how that is affecting the natural world are only now coming to light.”
“We had good reason to expect that increasing temperatures would lead to reductions in body size, based on earlier studies,” Weeks said. “I was incredibly surprised that all of these species are responding in such similar ways.”
The researchers plan to continue studying the Field Museum data in an effort to find additional evidence to support their findings. They will also further examine the idea that an individual’s physical development can change to fit changing environmental conditions.
1.Which of the following didn’t go down to a lower level?
A.The body size B.The body weight
C.The leg bone length D.The wingspan
2.Which of the following took responsibility for measuring the birds?
A.Ecology Letters B.Brian Weeks
C.The Field Museum D.Dave Willard
3.What does the underlined words “coming to light” in Paragraph5 mean?
A.Known B.similar
C.intelligent D.distant
4.The main idea of the passage is that
A.fifty-two species of birds became smaller.
B.the warming climate could affect bird growth.
C.the warming climate makes the birds grow larger.
D.the researchers have proved their findings.
