When we see well, we do not think about our eyes very often. It is only when we cannot see perfectly that we realize how important our eyes are.
People who are near-sighted can only see things that are very close to their eyes. Everything else seems unclear. Many people who do a lot of work, such as writing, reading and sewing become near-sighted.
Then people who are far-sighted endure just the opposite problem. They can see things that are far away, but they have difficulty in reading a book unless they hold it at arm’s length. If they want to do much reading, they must get glasses, too.
Other people do not see clearly because their eyes are not exactly the right shape. They have what is called astigmatism（散光）. This, too, can be corrected by glasses. Some people’s eyes become cloudy because of cataracts（白内障）. Long ago these people often became blind. Now however, it is possible to operate on the cataracts and remove then.
Having two good eyes is important for judging distances. Each eye sees things from a slightly different angle（角度）. To prove this to yourself, look at an object out of one eye; then look at the same object out of your other eye. You will find the object’s relation to the background and other things around it has changed. The difference between these two different eye views helps us to judge how far away an object is. People who have only one eye cannot judge distance as people with two eyes.

Children and teenagers who spend lots of time in front of screens---especially TVs---are easier to get more weight as they grow, according to a new study.
The findings agree with the research suggesting all that inactive sitting and always watching advertisements may lead to poor eating habits.
Researchers used results from a long-term study of children who took part in the surveys every two years. Children were between ages 9 and 16 when the study started. Out of 4,300 girls in the study, 17 percent were overweight or obese（肥胖的）. Twenty-four percent of the 3,500 boys were also above a healthy weight.
The surveys included questions about their height and weight as well as how much time they spent watching TV and DVDs and playing computer and video games.
From one survey to the next, each one-hour increase in children’s daily TV watching was in connection with an increase of about 0.1 points on a body mass index (BMI)（体质指数）, which measures weight in connection with height. There’s an increase of about half a pound in weight per extra hour of TV.
“The weight of the evidence is so strong that television watching is connected with unhealthy changes in weight among youth,” says Jennifer Falbe, who led the study while at the Harvard School of Public Health in Boston.
“It's important for parents to know that all the obesity-causing（引起肥胖的）screens really should be limited in their children's lives.” Falbe says. “When children watch TV, there are many food advertisements on TV that might lead them to eat a cookie or drink a soft drink.” What's more, she says, “they can get into a hibernating(冬眠) state on the sofa, even if children are sitting down while playing a computer game.”
【小题1】Which of the following statements can be the best title for the text?
| A．A new study on screens. |
| B．TVs do harm to children. |
| C．The less TV time, the fatter. |
| D．Too much screen time leads to obesity. |
| A．4,300 | B．3,500 |
| C．7,800 | D．9,800 |
| A．0.1 | B．0.5 |
| C．0.3 | D．0.7 |
| A．Limiting the time of children watching TV. |
| B．Buying children food advertised on TV. |
| C．Not allowing children to watch TV. |
| D．Encouraging children to play computer games. |

China has recently been faced with serious issues of product safety. In Panama, it is said that medicine made with a poisonous chemical sickened some people. A Chinese company had identified it as diethylene glycol, a low – cost substitute commonly used in automobile antifreeze.
Some countries have banned Chinese-made toothpaste containing diethylene glycol. China has now told companies to discontinue its use, even though it says the toothpaste is safe. Another industrial chemical, melamine, was found in wheat flour used to make pet food in North America. Thousands of dogs and cats became sick.
The United States has restricted some imports of Chinese seafood because they contained banned substance. And questions have been raised about other products, including children’s toys covered with lead paint.
Chinese officials promised to provide the European Union, the biggest trading partner, with detailed reports on enforcement efforts against unsafe goods.
Meglena Kuneva, commissioner (理事) for consumer protection of the European Union said China should have kept its promise.
China recently closed three companies linked to the Panama and the pet food scare. And it dismissed the former head of its food and drug administration. He was found guilty of corruption (腐败) for approving unsafe drugs. This week, a conference of the State Council approved a proposed special measure on the supervision of food safety. The Xinhua News Agency said it calls for stronger controls over producers, greater responsibilities for government and more serious punishment for illegal activities.
But Chinese officials have accused some foreign media of overstating problems with goods made in China. They say food imports from the United States also fail inspection sometimes. Next Week, American and Chinese food safety officials are planning to hold 5 days of meetings in Beijing to discuss cooperation.

A recent study suggests that teens’ relationship with parents, friends and teachers may have a lot to do with why they don’t get a good night’s sleep.
David Maume, a sociologist and sleep researcher, analyzed federal health data, which interviewed 974 teenagers when they were 12, and then again at 15. He found that family dynamics (动态) have much to do with how well kids sleep. Teens, who had warm relations with their parents and felt like they could talk to them or their parents were supportive of them, tended to sleep better. However, families that were going through a divorce or a remarriage tended to affect teens’ sleep.
And problems at school also affected teens’ sleep. Feeling safe at school and having good relations with teachers tended to promote better sleep. As did good relationships with friends. Kids who took part in sports or other positive social activities or shared similar academic goals with their friends were also more likely to get a good night’s sleep.
These add up to what makes lots of sense: a general feeling of well-being helps teens sleep. If we’re happy and contented, we’re much more likely to sleep better than if we’re sad and anxious.
Now, of course, teens can hardly resist being drawn to their computers and social networking. Maume also found that when parents were strict not only about bedtime, but also about limiting technology, kids slept better. It’s a finding that seems obvious, but parents really do matter when it comes to health habits of their teenagers.
Clearly, teenagers aren’t getting 9 to 10 hours a night, which puts them at risk for all the consequences of lack of sleep, including poor academic performance, colds and stress.
【小题1】What is the passage mainly about?
| A．Teens’ sleep is linked to their relationship with people around them. |
| B．Lack of adequate sleep puts teens at risk of many bad consequences. |
| C．Modern technology has something to do with teens’ sleep problems. |
| D．It is necessary for teens to join in sports and positive social activities. |
| A．Teens who feel like talking with their parents. |
| B．Teens who have friends sharing their dreams. |
| C．Teens who feel contented about themselves. |
| D．Teens who lack a sense of security at school. |
| A．a comparison | B．an introduction | C．a conclusion | D．an addition |
| A．continue their broken marriage |
| B．allow children to decide when to sleep |
| C．limit teens’ using new technology |

Country-dwellers(农村居民) often say the constant noise, heavy traffic and crowds of the city would drive them mad. Well, they might be right, according to the latest research. City residents are more likely to develop mental illnesses than those who live in villages, a study has found.
Researchers from Cardiff university examined the lifestyles of more than 200,000 people in Sweden and found that those who lived in urban areas were more at risk from mental illnesses than people who lived in villages.
The experts don’t know exactly why this is but they suggest that town and city residents are more likely to be ostracized(排挤) by those around them. They are more likely to experience discrimination(歧视) if they do not fit in, which can lead to them feeling anxious and even developing mental illnesses.
Dr Stanley Zammit, who led the research said that people living in towns and cities are more likely to develop other mental illnesses that result in personality changes — a condition known as non-affective psychosis(非情感性精神病).
Earlier this year an official report found that village-dwellers live an average of two years longer than those living in towns and cities. According to figures from the Office of National Statistics in the UK, men who live in villages are likely to live for between 78 and 79 years, while those in towns and cities can expect to survive to an age of 76. Women on average survive to their 81st birthday in towns and cities, but live to between 82 and 83 in villages. The small marked town of Wimborne Minster in rural Dorset was named the healthiest place to live in.

LEEDS, England—A Leeds University psychology professor is researching a course to help dozens of Britons forgive their enemies.
“The hate we hold within us is a cancer.” Professor Ken Hart said, adding that holding in anger can lead to problems such as high blood pressure and heart disease.
More than 70 people have become volunteers in Hart’s first 20-week workshop in London—a course he says is the first of its kind in the world.
These are people who are sick and tired of living with a memory. They realize their bitterness is a poison they think they can pour out, but they end up drinking it themselves, said Canadian-born Hart.
The students meet in each group of eight to ten for a two-hour workshop with a director every two weeks.
The course, ending in July, is expected to get rid of the cancer of hate in these people. “People have lots of negative attitudes towards forgiveness,” he said, “People confuse forgiveness with forgetting. Forgiveness means changing from a negative attitude to a positive one.”
Hart and his team have created instructions to provide the training needed.
“The main idea is to give you guidances on how to look at all kinds of angers and how they affect you, and how to change your attitudes towards the person you are angry with,” said Norman Claringbull, a senior expert on the forgiveness project.
Hart said, “I believe forgiveness is a skill that can be taught, as these people want to get free of the past.”
【小题1】From this passage we know that ________.
| A．without hate, people will have less trouble connected with blood pressure and heart disease |
| B．people who suffer from blood pressure and heart disease must have many enemies |
| C．high blood pressure can only be cured by psychology professors |

Putting in water fountains(饮水器) at schools, and teaching children about the health benefits of water, could reduce their risk of getting extra pounds, reports a new study that is published in the latest issue of the journal pediatrics.
The findings are based on a survey in 32 elementary schools of two German cities, Dortmund and Essen. The researchers, led by Rebecca Muckelbauer, a nutrionist at the Research Institute of Child Nutrition Dortmund, weighed about 3,000 children, and asked them about their beverage(饮料) consumption.
At the beginning of the school year, the experts had water fountains added to 17 of the schools. The scientists also worked with teachers to carry out educational programs that promote the benefits of drinking water. In contrast to schools in the United States, there are very few schools in Germany that have water fountains.
At the beginning of the study, there were no big differences in the number of overweight children in different groups. But by the end of the school year, children in the schools with water fountains were 31 percent less likely to gain extra pounds, compared to kids who went to other schools, where water drinking was not encouraged.[来源:学
Children in the schools with fountains, increased their water consumption from about 3 up to 4 glasses a day, while those in the other schools continued to drink an average of 3 glasses. Over the research, the number of overweight kids upped from 384 to 385 out of 1,641 at the schools with water fountains. In comparison, the number of overweight kids at the other schools increased from 339 to 364 out of 1,309, Dr. Muckelbauer said.
The experts cannot make any final conclusions and explain why the students who were encouraged to drink water were less likely to gain extra weight. Dr. Muckelbauer noted that according to a few other studies, drinking of water increases the rate at which calories are burned, while some other research suggested that water may temporarily decrease appetite.
【小题1】According to the text, the journal Pediatrics__________.
| A．may cover the subject of the health of children |
| B．mainly deals with the water drinking problem |
| C．is mainly about the mental health of kids |
| D．must be a journal entitled(授权) by a school |
| A．The teacher were also encouraged to drink water. |
| B．The students surveyed were all overweight. |
| C．It surveyed children in the countryside. |
| D．It lasted for a whole school year. |
| A．the technique used in the survey | B．the benefits of the survey |
| C．the process of the survey | D．the result of the survey |
| A．Drinking water definitely decreases appetite. |
| B．Further research is needed to confirm the finding. |
| C．The experts will encourage all the students to drink water. |

When I was small and my grandmother died, I couldn’t understand why I had no tears. But that night when my dad tried to cheer (使…快活) me up, my laugh turned into crying.
So it came as no surprise to learn that researchers believe crying and laughing come from the same part of the brain. Just as laughing has many health advantages, scientists are discovering that so does crying.
Whatever it takes for us to reduce pressure is important to our emotional (情感的) health, and crying seems to work well. One study found that 85 percent of women and 73 percent of men report feeling better after crying.
Besides, tears attract help from other people. Researchers agree that when we cry, people around us become kinder and more friendly and they are more ready to offer support and comfort. Tears also enable us to understand our emotions better; sometimes we don't even know we're very sad until we cry. We learn about our emotions through crying, and then we can deal with them.
Just as crying can be healthy, not crying — holding back tears of anger, pain or suffering — can be bad for physical health. Studies have shown that too much control of emotions can lead to high blood pressure, heart problems and some other illnesses. If you have a health problem, doctors will certainly not ask you to cry. But when you feel like crying, don't fight it. It's a natural — and healthy — emotional response.
【小题1】Why didn't the author cry when her grandmother died?
| A．Because her father did not want her to feel too sad. |
| B．Because she did not love her grandmother. |
| C．Because she was too shy to cry at that time. |
| D．The author doesn’t give the explanation. |
| A．there are two ways to keep healthy |
| B．laughing does more good to health than crying |
| C．crying and laughing play the same roles |
| D．emotional health has a close relationship to physical health |
| A．Crying is the best way to get help from others. |
| B．Holding back tears may cause some health problems. |
| C．We will know our deep feelings if we cry. |
| D．We must cry if we want to reduce pressure. |
| A．Power of Tears | B．How to Keep Healthy |
| C．Why We Cry | D．A New Scientific Discovery |
| A．come back | B．pay back | C．hold back | D．give back |
