Teenagers who drink alcohol are at higher risk of becoming victims of violence, a Cardiff University study has found.

A team from the School of Dentistry’s Violence Research Group studied drinking habits in children aged 11 - 16 in England. They found not only a link between drink and violence but also that children who drank were more likely to be hit, even if they weren’t violent themselves.

The researchers are now calling for measures to prevent alcohol misuse to reduce injury risk. Current policy focuses on reducing aggression but this research shows that there should be equal effort to reduce victimization.

More than 4,000 children were surveyed at 13 schools at four local authorities in the North, the Midlands, London, and the South. The study found that 25% of 11-year-olds were drinking monthly and 3.6% daily, with 12.8% admitting to getting drunk 3 to 5 times a year. By the age of 16, 40% were drinking weekly and 6.2% were drinking every day. The research also showed 22.6% of 16-year-olds were getting drunk more than 21 times a year.

The study, which has just been published in the Journal of Adolescence, found a strong link between frequency of drinking and frequency of hitting other people.

However, children who reported drinking monthly were also three times more likely to be hit. Adolescents（青少年） who drank but didn’t get into fights were more likely to be hit than those who did fight.

Professor Jonathan Shepherd, who led the research, said a lot of previous alcohol-related violence work had focused on the offenders（惹事的人） rather than the victims. His team is calling for more prevention work from parents and teachers in the first two years of secondary school by taking advantage of the “teachable moment”, that is, immediately after a student has missed school because of drunkenness.

Previous work by Professor Jonathan Shepherd has shown drinkers may be more at risk of violence because of reduced physical co-ordination, poor decision-making in threatening situations and isolation while out late at night. He said, “This new study seems to be the first to show a direct link between alcohol misuse and victimization. There now needs to be much more effort put into reducing alcohol misuse in order to reduce injury.”

A. often offend other people

C. are more likely to fight with others

D. are more likely to become victims of violence

About half American teenagers do not get enough sleep on school nights.They get an average of sixty to ninety minutes less than experts say they need.

One reason for this is biology.Experts say teens are biologically programmed to go to sleep later and wake up later than other age groups.Yet many schools start classes as early as seven in the morning.As a result，many students go to class feeling like sixteenyearold Danny.He is an active teen— except in the morning.“Getting up in the morning is pretty terrible.I’m just very out of it and tired.Through the first and second period I can hardly stay awake,” he said.

Michael Breus is a psychologist.Teens，he says，need to sleep eight to nine hours or even nine to ten hours a night.He says sleepy teens can experience a form of depression(消沉) that could have big influence on their general well being.It can affect not just their ability in the classroom but also on the sports field and on the road.So what can schools do about sleepy students？The psychologist says one thing they can do is to start classes later in the morning.Studies show that students can improve by a full letter grade in their first and second period classes.

Eric Peterson is the head of St.George’s School in the northeastern state of Rhode Island.He wanted to see if a thirtyminute delay(推迟)would make a difference.It did.He says visits to the health center by tired students decreased by half.Late arrivals to the first period fell by a third.And students reported that they were less sleepy during the day.Eric Peterson knows that changing start times is easier at a small school like his.But he is hopeful that other schools will find a way.

1.What’s the best title for the passage?

A．Later classes，fewer sleepy teens

B．Early birds have good food

Elderly women who eat foods higher in potassium（钾）are less likely to have strokes and die than women who eat less potassium-rich foods, according to new research in the American Heart Association. “Previous studies have shown that potassium consumption may lower blood pressure. But whether potassium intake could prevent stroke or death wasn’t clear,” said Smoller, professor of the department of population health at Albert Einstein College of Medicine, Bronx, NY.

Researchers studied 90,137 women, aged from 50 to 79 for an average 11 years. They looked at how much potassium the women consumed, as well as if they had strokes, including ischemic strokes (缺血性中风), or died during the study period. Women in the study were stroke-free at the start and their average dietary potassium intake was 2,611 mg/day. Results of this study are based on potassium from food, not supplements.

The researchers found: Women who ate the most potassium were 12 percent less likely to suffer stroke in general and 16 percent less likely to suffer an ischemic stroke than women who ate the least. Women who ate the most potassium were 10 percent less likely to die than those who ate the least. Among women who did not have high blood pressure, those who ate the most potassium had a 27 percent lower ischemic stroke risk and 21 percent reduced risk for all stroke types, compared to women who ate the least potassium in their daily diets. Among women with high blood pressure, those who ate the most potassium had a lower risk of death, but potassium intake did not lower their stroke risk.

“Our findings suggest that women need to eat more potassium-rich foods. You won’t find high potassium in junk food. Some foods rich in potassium include white and sweet potatoes, bananas and white beans.”

The U.S. Department of Agriculture recommends that women eat at least 4,700 mg of potassium daily. “Only 2.8 percent of women in our study met or went beyond this level. The World Health Organization’s daily potassium recommendation for women is lower, at 3,510 mg or more. Still, only 16.6 percent of women we studied met or went beyond that,” said Smoller.

While increasing potassium intake is probably a good idea for most elderly women, there are some people who have too much potassium in their blood, which can be dangerous to the heart. “People should check with their doctor about how much potassium they should eat,” she said.

The study was observational and included only elderly women. Researchers also did not take sodium (钠) intake into consideration, so the potential importance of a balance between sodium and potassium is not among the findings. Researchers said more studies are needed to determine whether potassium has the same effects on men and younger people.

1.The benefits of potassium intake to elderly women do not include ______.

A. preventing strokes　　 B. lowering blood pressure

C. cutting down death risks　　 D. reducing heart attacks

2.Which of the following figure meets the daily potassium intake recommendation of the World Health Organization?

A. 2,500 mg.　　 B. 3,000 mg.

C. 3,500 mg.　　 D. 4,000 mg.

3.What conclusion can be drawn from the research findings?

A. Increasing potassium is definitely a good idea for all elderly women.

B. Potassium intake is more beneficial to those without high blood pressure.

C. Elderly women with high blood pressure benefit more from potassium.

D. There was not any association between potassium intake and ischemic strokes.

Baekeland and Hartmann report that the “short sleepers” had been more or less average in their sleep needs until the men were in their teens. But at about age 15 or so, the men voluntarily began cutting down their nightly sleep time because of pressures from school, work, and other activities. These men tended to view their nightly periods of unconsciousness as bothersome interruptions in their daily routines.

In general, these “short sleeps” appeared ambitious, active, energetic, cheerful, conformist(不动摇) in their opinions, and very sure about their career choices. They often held several jobs at once, or workers full-or part-time while going to school. And many of them had a strong urge to appear “normal” or “acceptable” to their friends and associates.

When asked to recall their dreams, the “short sleepers” did poorly. More than this, they seemed to prefer not remembering. In similar fashion, their usual way of dealing with psychological problems was to deny that the problem existed, and then to keep busy in the hope that the trouble would go away.

The sleep patterns of the “short sleepers” were similar to, but less extreme than, sleep patterns shown by many mental patients categorized as manic(疯人).

The “long sleepers” were quite different indeed. Baekeland and Hartmann report that these young men had been lengthy sleeps since childhood. They seemed to enjoy their sleep, protected it, and were quite concerned when they were occasionally deprived of their desired 9 hours of nightly bed rest. They tended to recall their dreams much better than did the “short sleepers.”

Many of the “long sleepers” were shy, anxious, introverted (内向), inhibited (压抑), passive, mildly depressed, and unsure of themselves (particularly in social situations). Several openly state that sleep was an escape from their daily problems.

64. According to the report,______.

A) many short sleepers need less sleep by nature

B) many short sleepers are obliged to reduce their nightly sleep time because they are busy with their work

C) long sleepers sleep a longer period of time during the day

D) many long sleepers preserve their sleeping habit formed during their childhood

65. Many “short sleepers” are likely to hold the view that _____.

A) sleep is a withdrawal from the reality

B) sleep interferes with their sound judgement

C) sleep is the least expensive item on their routine program

D) sleep is the best way to deal with psychological troubles

66. When sometimes they cannot enjoy adequate sleep, the long sleepers might ____.

A) appear disturbed

B) become energetic

C) feel dissatisfied

D) be extremely depressed

67. Which of the following is Not included in the passage?

A) If one sleeps inadequately, his performance suffers and his memory is weakened

B) The sleep patterns of short sleepers are exactly the same as those shown by many mental patients

C) Long and short sleepers differ in their attitudes towards sleep

D) Short sleepers would be better off with more rest

高二英语阅读理解简单题查看答案及解析

We walk, talk and sleep with our phones. But are we more — or less-connected? Just as remarkable as the power of mobility, over everything from love to global development, is how fast it all happened. It is hard to think of any tool, any instrument, any object in history with which so many developed so close a relationship so quickly as we have with our phones. Not the knife or match, the pen or page. Only money comes close—always at hand, don't leave home without it. But most of us don't take a wallet to bed with us. don't reach for it and check it every few minutes, and however useful money is in pursuit of fame, romance, revolution, it is inert compared with a smart phone — which can replace your wallet now anyway.

So how do we feel about this? To better understand attitudes about mass mobility, Time, in cooperation with Qualcomm, started the Time Mobility Poll, a survey of close to 5,000 people of all age groups and income levels in eight countries. Even the best survey can be only a snapshot in time, but this is revealing a lot about both where we are now and where the mobile wave is taking us next.

Not for a day — in most cases not even for an hour. In Time's Poll, 1 in 4 people check it every 30 minutes, 1 in 5 every 10 minutes. A third of respondents admitted that being without their mobile for even short periods leaves them feeling anxious. It is a form of sustenance, that constant feed of news and notes and nonsense, to be the point that twice as many people would pick their phones over their lunch if forced to choose. Three-quarters of 25-to 29-year-olds sleep with their phones.

Americans are grateful for the connection and convenience their phones provide, helping them search for a lower price, navigate a strange city, expand a customer base or track their health and finances, their family and friends. But in some ways Americans are still ambivalent （矛盾的）; more than 9 in 10 Brazilians and Indians agreed that being constantly connected is mostly a good thing. America's 76% was actually the lowest score.

1.What can have a comparison with phones?

A.A pen. B.A knife.

C.A match. D.Money.

2.It can be inferred that a smart phone can also have the function of ______

A.paying bills. B.helping sleep.

C.pursuit money. D.cutting things.

3.Why did Time start the Time Mobility Poll?

A.Because it wanted to cooperate with Qualcomm.

B.Because it wanted to know where the mobile wave was taking us.

C.Because it wanted to learn people's attitudes to mass mobility

D.Because it wanted to know how well the mobile wave went.

4.What does Paragraph 3 mainly tell us?

A.Mobile phones have become a tool to sleep with.

B.Mobile phones have become a way to get news.

C.Mobile phones have become a tool to order food.

D.Mobile phones have become a must in daily life.

5.According to the passage. Americans are less ______.

A.likely to show appreciation to their phones.

B.constantly connected than Indians.

C.likely to search for a lower price.

D.likely to find ways in a strange city.
