Teenagers who start the school early are likely to weigh slightly more than those who start later. That’s the finding of a new study of nearly 30,000 Canadians between the ages of 10 and 18.
Getting too little sleep can put kids at risk for a number of problems. Sleepy teens are more likely to be overweight, to have trouble concentrating and to struggle in school. Genevieve Gariepy, who works at Mcgill University in Montreal, Canada, wanted to know how earlier school start times might be connected with weight.
“Overweight in teenagers is a big problem in North America,” she says. The number of overweight kids has grown over the past 30 years. So Gariepy decided to home in on the impact (影响) of school start times.
Her team collected start times for 362 Canadian schools. Then they asked students at those schools to give their height and weight. In all, they collected data from nearly 30,000 10 to 18-year-olds. Among 6th-to 10th-graders, those who started school earlier were likely to be slightly heavier for their height. Every 10-minute delay in school start time was connected, on average, with a lightly lower weight among students who were the same sex, age and height. However, the difference is slight. Healthy eating and getting enough exercise will play a bigger role in keeping a healthy weight.
Because the study compared kids who already started school at different times of day, it’s not clear that changing school start time would help heavier kids lose weight. To know for sure, researchers would want to compare the same kids before and after changing to a later school start time.
Still, the study is a good start, says Cora Collette Bruener, a doctor at Seattle Children’s Hospital in Washington. The findings add to a growing pile of evidence that later school start time might be better for teen health, she says.
1.What is the finding of the new study?
A.More and more teens are growing overweight.
B.Healthy diets and enough exercise help reduce weight.
C.Teens who start school earlier are a little overweight.
D.Teens who start school earlier do not perform well.
2.What does the underlined phrase “home in on” in paragraph 3 probably mean?
A.reduce B.focus on
C.move to D.judge
3.How did Gariepy’s team get their finding?
A.By recording the teen’s weight. B.By checking the teen’s physical health.
C.By comparing different sets of data. D.By measuring the teen’s height.
4.What does Cora Collette Bruener think of the study?
A.It has inspiring value. B.It lacks further support.
C.It needs improving. D.It is well designed.
5.The passage is written to_______.
A.discuss when schools should start.
B.inform the finding of a recent study.

What are American high schools like? Well, I’m happy to tell you what I know.
When I started school here, it had already been a week since the school opened. At this school, freshmen usually go on a trip for about three days at the beginning of school. Unfortunately I missed that wonderful trip, which would have been the best time to get to know my classmates. I was really sad. I wished I’d known about it earlier.
Despite the disappointment, however, I gradually adapted to my new life and school.
There is a space in the basement of the teaching building where students chat and meet each other. As we do not always have the same classrooms and classmates, the school wants us to get to know each other there. Students usually come to school early, sit in that space and have fun. Around the space, there are many lockers for students to leave their books in, so that students do not have to carry a heavy schoolbag everywhere.
It really surprises me that we have almost no textbooks. We only have textbooks for World History and Algebra 2 and they are big and heavy, like bricks. For other classes, we only need binders (活页夹) with paper in them. Without textbooks, students learn things freely and actively. For example, my humanities teacher just teaches us what is in her mind at the time. We never know what we will learn.
Another difference between American schools and Chinese schools is that American schools care about students’ morality more than their academic studies. For example, if you do not finish your homework, you will just be asked to do it later, but if you cheat or lie, you will get a warning or even be kicked out.
I think that most students here are good at schoolwork as well, but compared to Chinese students, they can make learning a more joyful experience. I think we should take the good points from our two different kinds of education to perfect our approach to studying.
1.What was the writer sad for?
A. He was late for school.
B. He missed the trip at the beginning of school.
C. He didn’t know anyone.
D. American students looked down upon him.
2.Why do students go to the basement of the teaching building?
A. To attend class. B. To share a classroom.
C. To have fun. D. To meet teachers.
3.How do teachers in the US teach the students?
A. However they want to. B. They use bricks.
C. Some use textbooks; some teach freely. D. They always teach as required.
4.According to the passage, in American high schools, ________.
A. you are likely to be kicked out if you cheat
B. you’ll be punished if you do not finish your homework
C. students are better at school work than Chinese students
D. students care much about the grades they get

As a recent research shows that the more teenagers watch television, the more likely they are to develop depression（抑郁症）as young adults.
The researchers used a nationwide long-term survey of adolescent（青少年的） healthy to investigate（调查）the relationship between media use and depression. They based their findings on more than four thousand adolescents who were not depressed when the survey began in 2000.
As part of the survey, the young people were asked how many hours of television or videos they watched daily. They were also asked how often they played computer games and listened to the radio. Media use totaled an average of five and one-half hours a
day. More than two hours of that was spent watching TV.Seven years later, in 2007, more than seven percent of the young people had signs of depression. The average age at that time was twenty one.
The researchers say they did not find any such relationship with the use of other media such as movies, video games or radio etc. But the study did find that every extra hour of television meant an eight percent increase in the chances of developing signs of depression. Young men were more likely than young women to develop depression given the same amount of media use.
The study didn’t explore if watching TV causes depression. But one possibility is that it was taking time away from activities that could help prevent depression.
Last December, the journal Social Indicators Research published a study of activities that help lead to happy lives. Sociologists from the University of Maryland found that people who describe themselves as happy spend less time watching television than unhappy people. The study found that happy people are more likely to be socially active, to read, attend religious services and to vote.
1.What is the best title of this passage?
A. Media Use is Harmful to Adolescents
B. Men Develop Depression Easier than Women
C. Teens, Television and Depression
D. Take Great care of Teenager’s depression
2.The result of the research seems to indicate .
A. teenagers are more likely to develop depression than adults
B. other media uses do no harm to adolescents
C. those who watch no TV will not develop depression
D. TV probably causes teenagers to grow up with depression
3.It can be inferred from the passage that .
A. longer use of media other than TV doesn’t increase the chance of depression
B. every extra hour of media use increases the chance of depression
C. depression is related to the use of other media other than TV
D. the influence of movies, video games and radio on depression varies

Early risers are most likely to be healthy, wealthy and wise, according to the old saying. But those who are early to bed and early to rise do not always have advantages, researchers say. They have found that night owls（夜猫子） are generally brighter and wealthier than those who are able to get up early in the morning.
Experts from the University of Madrid carried out tests on around 1,000 teenagers and found that those who preferred to stay up late showed the kind of intelligence to find good jobs and earn much money. Larks or “morning people”, however, often get better exam results, possibly because lessons are held at the wrong time of day for night owls.
The researchers examined the habits and body clocks of the young people to determine whether they liked to stay up late and sleep later in the morning, or preferred to go to bed early and were at their best state in the morning. School performance and problem solving ability, were judged and test grades in the major subjects were also taken into consideration.
Jim Horne, professor of psychophysiology at Loughborough University, said: “Evening types tend（倾向） to be the more creative types, the poets, artists and inventors, while the morning types are considered to be civil servants and accountants（会计）. ”
1.The researchers from the University of Madrid found _______.
A．morning people will probably find good jobs and earn a lot

2.Early risers often do well in exams possibly because_______.
A．they go to bed by 10p.m. regularly
B．they make full preparations before exam
C．lessons are held at the right time for them
D．they have longer time to prepare for their lessons
3.The research may include questions about the following EXCEPT_______.

When your children become teenagers, it’s time to start considering an after-school job.
1., so why shouldn’t our children? When your child has a job, he/she is responsible for getting to work on time and doing his/her job correctly. An after-school job is a good way to teach your teenager about responsibility.
By allowing your teenagers to have an after-school job you allow them to learn about money management. 2., they will have to manage how much money they can spend. They will realize that they can’t spend every dollar they make if they want to reach their goal.
You are probably saying, “Teens will get into trouble whether they have a job or not.”
3.. Depending on the distance from work to home, you could allow your children some extra time to get home after work. This will ensure that they don’t feel rushed but can still get home on time.
It’s a good idea to show your teenagers that hard work is what it takes to finish everything in their lives. 4.. What will they expect when they are out on their own if they have never had to work hard for what they want?
5.. All teenagers, no matter what their parents’ financial situation is, should have a job. They will need the experience before they do get out in the real world.
A. If they are saving up for their first car
B. When they refuse to have an after-school job
C. It is a good idea for all teenagers to have an after-school job
D. Most of adults in the U.S. had a job during their teenage years
E. They can’t learn the meaning of hard work if everything is handed to them
F. Having an after-school job will help your teenagers know their direction
G. But it is less likely that your children will get into trouble if they are working five evenings a week.

Larks are most likely to be healthy, wealthy and wise, according to the old saying.
But those who are early to bed and early to rise do not always have the upper hand, researchers say. They have found that night owls are generally brighter and wealthier than those able to get up early in the morning.
Experts from the University of Madrid carried out tests on around 1,000 teenagers and found that those who preferred to stay up late proved the kind of intelligence associated with honored jobs and higher incomes. “Larks” or “morning people”, however, often acquired better exam results, possibly because lessons are held at the wrong time of day for night owls. The researchers examined the habits and body clocks of the youngsters to determine whether they liked to stay up late and sleep in later in the morning, or preferred to go to bed early and were at their peak in the morning. School performance and inductive（归纳的）intelligence, or problem solving, were measured and academic grades in the major subjects were also taken into account. The results showed that evening types scored higher than morning types on inductive reasoning, which has been shown to be a good estimate of general intelligence and a strong indicator of academic performance. They also had a greater capacity to think conceptually as well as analytically. Such abilities have been linked to innovative（创新的） thinking, more admired occupations and better incomes.
Famous night owls include President Trump, Obama, Charles Darwin, Winston Churchill, Keith Richards and Elvis Presley. George W. Bush, who is regularly in bed by 10 p.m., Thomas Edison, Napoleon, Condoleezza Rice, who wakes at 4:30 a.m., and Ernest Hemingway are among those known as larks. Jim Horne, professor of psychophysiology at Lough borough University, said, “Evening types tend to be the more active and creative types, the poets, artists and inventors, while the morning types are the deducers（推断者）, as are often seen with civil servants and accountants.” A previous study of US Air Force recruits found that evening types were much better at thinking to solve problems than larks.
1.What does the word “lark” mean in the text?
A.A bird of prey that flies in the morning.
B.A bird of prey that is a symbol of wisdom.
C.A kind of person who goes to bed early and wakes up early.
D.A kind of person who has honored jobs and higher incomes.
2.What characteristics do night owls have?
A.Night owls are much healthier, wealthier and wiser.
B.Night owls are not good at inductive reasoning.
C.Night owls stay up late and wake up early in the morning.
D.Night owls are expert in analyzing and innovative thinking
3.What’s the author’s attitude towards night owls?
