Nowadays the U.S. students are sleepy in school because they spend too much time texting, playing video games, watching TV, and using the media in other ways.
"Heavy media use interferes with sleep by reducing sleep duration, making it harder to fall asleep, and lowering sleep quality," Meilan Zhang, an assistant professor at the University of Texas at E1 Paso, wrote in her research review in the journal, Sleep Medicine.
But the relationship between youth's media use and sleep is not so simple, said Michael Gradisar, who authored both that review and the Sleep Medicine meta-analysis. "Technology use is the new evidence when we are trying to answer 'Why are school-age children sleeping less?" said Mr. Gradisar, an associate professor of psychology at Flinders University in Adelaide, Australia.
There may be safe limits to technology use, Mr. Gradisar stated. For instance, recent research results indicate that using a bright screen for an hour before bed or even playing violent video games for less than that will not necessarily interfere with teenagers' sleep, he wrote.
But longer periods of usage can be harmful to sleep, Mr. Gradisar added. Rather than delaying school start times, he said, the first step should be educating parents about limiting the hours that their children are using technology before bed, and enforcing a consistent bedtime.
Early school start times are also commonly blamed for students' sleepiness, especially for adolescents. Secondary schools around the nation and the world have been delaying start times, often with positive results.
Mr. Minnich of the TIMSS and PIRLS International Study Center hesitated to put blame to any particular factor. But he did think that cost-saving measures to consolidate (合并) bus routes might help explain U.S. students' sleepiness.
"For those children who board the bus first, they must get up earlier, may end up sleeping on the way to school, and may end up arriving at school sleepy." he said.

Nowadays people are putting our water supply in danger, because they use too much water or throw rubbish into the river. You may wonder how paving(铺砌) a road can lead to less usable fresh water. A major part of thewaterweuse every day is groundwater. Groundwater does not come from lakes or rivers. It comes from underground. The more roads and parking lots we pave，the less water can flow into the ground to become groundwater.
Human activity is not responsible for all water shortages(短缺). Drier climates are of course more likely to have droughts(干旱) than areas with morerainfall，but in any case, good management can help to make sure there is enough water to meet our basic needs.
Thinking about the way we use water every day can make a big difference，too. In the United States，a family of four can use 1.5 tons of water a day! This shows how much we depend on water to live，but there's a lot we can do to lower the number.
You can take steps to save water in your home. To start with，use the same glass for your drinking water all day. Wash it only once a day. Run your dishwasher (洗碗机)only when it is full. Help your parents fix any leaks in your home. You can even help to keep our water supply clean by recycling batteries instead of throwing them away.
1.Which of the following is most likely to lead to less groundwater?
A．Using river water.
B．Throwing batteries away.
C．Paving parking lots.
D．Throwing rubbish into lakes.
2.What can be inferred from the text?
A．All water shortages are due to human behavior.
B．It takes a lot of effort to meet our water needs.
C．There is much we can do to reduce family size.
D．The average family in America makes proper use of water.
3.The last paragraph is intended to________．
A．show us how to fix leaks at home
B．tell us how to run a dishwasher
C．prove what drinking glass is best for us
D．suggest what we do to save water at home
4.The text is mainly about________．
A．why paving roads reduces our water
B．how much we depend on water to live
C．why droughts occur more in dry climates
D．how human activity affects our water supply

Students who date(约会) in middle school have significantly worse study skills. They are four times more likely to drop out of school and report twice as much alcohol and tobacco use as their single classmates, according to new research from the University of Georgia.
“Romantic relationships are a trademark of adolescence, but very few studies have examined how adolescents differ in the development of these relationships,” said Pamela Orpinas, study author and professor in the College of Public Health and head of the Department of Health Promotion and Behavior.
Orpinas followed a group of 624 students over a seven-year period from 6th to 12th grade.
Each year, the group of students completed a survey indicating whether they had dated and reported the frequency of different behaviors, including the use of drugs and alcohol. Their teachers completed questionnaires about the students’ academic(学术的) efforts. He found that some students never or hardly ever reported dating from middle to high school, and these students always had the best study skills according to their teachers. Other students dated infrequently in middle school but increased the frequency of dating in high school.
“At all points in time, teachers considered the students who reported the lowest frequency of dating as having the best study skills and the students with the highest dating as having the worst study skills,” according to the journal article. Study skills refer to behaviors that lead to academic success such as doing work for extra credit (学分), being well organized, finishing homework, working hard and reading assigned chapters.
“Dating a classmate may be as complicated as dating a co-worker,” Orpinas said, “when the couple break up, they have to continue to see each other in class and perhaps see the ex-partner dating someone else. It is reasonable to think this could be linked to depression and could divert (转移) attention from studying.”
“Dating should not be considered a ceremony of growth in middle school,” Orpinas concluded.
1.According to the passage, students who date in middle school may_____
A. have poorer academic performances
B. be more likely to hurt others
C. enjoy better school lives
D. be less likely to use alcohol and tobacco
2.When doing his study, Orpinas ________________.
A. followed a group of students of 6th and 12th grade
B. completed a survey and a report each year
C. found that the students’ study skills have connection with their frequency of dating
D. completed questionnaires about the students’ academic efforts
3.What can possibly happen to the school couples after they break up?
A. They don’t want to see each other any longer.
B. They will think it’s reasonable to get depressed.
C. They will miss their ex-partners sometimes.
D. Their attention to studying will be affected.
4.Orpinas’ attitude towards dating in middle school is_____
A. supportive B. negative
C. positive D. Unconcerned

School Uniforms in Japan
For students, school uniforms in Japan are not only symbols for schools, but also symbols for the current fashion trends, even affecting students when choosing a school. Japanese school uniforms for girls originate in sailor suits. So they are also called sailor suits or sailor uniforms. Cartoon elements are used on them.
