A new study has found evidence of aggressive (攻擊性的) behavior in children who drink four or more servings of soft drinks every day. Information for the study came from the mothers of 3,000 5-year-olds. Researchers asked the women to keep a record of how many servings of soft drinks their children drank over a two-month period. They were also asked to complete a checklist of their children’s behavior.
The researchers have found that 43 percent of the children drink at least one daily serving of soda, and 4 percent of the youngsters have even four or more sodas to drink every day.
Shakira Suglia, a famous expert, says they’ve found that children who drink the most soda are more than twice as likely as those who drink no soda to show signs of aggression.
“For the children who consume four or more soft drinks per day, we see more withdrawn behaviors, which make them hard to get along well with others.”
The aggressive behaviors include destroying possessions belonging to others, taking part in fights and physically attacking people.
The researchers have determined the link after considering factors like the child’s age and sex. They have also considered other possible influence, such as whether the boys and girls are eating sweets or giving fruit drinks on a normal day. In addition, the researchers have examined parenting styles and other social conditions that may be taking place in the home.
Researches are trying to find why young children who drink a lot of soda have behavior problems. An ingredient often found in soft drinks is caffeine, which helps to make people feel energetic. Doctor Suglia suggests that caffeine could cause the 5-year-olds to be more aggressive. Earlier studies of adults have found the highest sugar levels in those who carry weapons (武器) and show signs of negative social behavior.

Jungle country is not friendly to man, but it is possible to survive there. You must have the right equipment and you must know a few important things about woodcraft. Then your chances of staying alive are very good.
No one should go into the jungle without the right equipment. You need light weight clothing, a good knife, and a compass. Fishhooks and a line, a rifle, matches in a waterproof container and a poncho are necessary too. So is a mosquito net to protect the head.
In the jungle you can get hopeless lost within five minutes after leaving a known landmark. That is why you should always carry a compass. In open country, during the day, you can tell which way o go by studying the sun. At night the stars are sure guides o direction. But in most places the jungle rooftop is so thick that it is impossible to see the sun or the stars. Again and again you must check your position by the compass.
Keep alert. Watch the ground in front of you carefully. Stop and listen now and again. Avoid haste, and rest often. In a place that is hot and humid, the person who sets a fast pace will soon become tired. A steady, even pace is wisest in the long run.  
If you lose your way, don’t panic. Try to desire how long it has been since you were sure of your position. Mark the spot where you are with blazes on a tree. Put them on four sides of the tree, so that you will be able to see them from any direction. Then you can begin retracing your steps, knowing that you can always find the spot from which you started. Except in an emergency, never try to travel through the jungle at night.
Whenever possible, it is wise to follow streams and rivers that are going in your general direction. This may cause you many extra miles of travel. But in the end it will save time and energy. Nothing is more exhausting than hacking a trail cross-through umbrella jungle.
If a river is broad and deep and has no rapids, rafting is the best means of travel. Bamboo grows along the banks of many jungle streams. Since it is hollow and extremely strong, it makes a perfect raft.
Surviving in the jungle is a science. The jungle people have become perfect in this science, and you can too. Learn as much as you can about what to expect in the jungle. Make sure you have the right equipment. Then no part of the jungle will be able to “l(fā)ive off” it for a long time.
小題1: The author probably advises against traveling at night because ________.
one tends to move too slowly at night
some animals will attack you
emergencies occur most frequently at night
it is more difficult to check your position
小題2:Following streams and rivers will help you to ________.
avoid animal’s attacks
save many extra miles of travel
avoid crossing unbroken stretches of jungle
have a constant source of drinking water  
小題3:The word “blazes” in Paragraph 5 means _________.
A．marks where bark (樹皮) is removedB．light-colored spots
C．bursts of flameD．sides of knife

Some kinds of mental skills naturally decrease as people get older. Yet research seems to show that some training can improve such skills. A recently published study also appears to demonstrate that the good effects of training can last for many years after that training has ended.
Researchers at Johns Hopkins University in Maryland wanted to learn how long memory and thinking skills would last in older people who trained to keep them. The people were part of the ten-year research project. They were taught methods meant to improve their memory, thinking and ability to perform everyday tasks.
More than 2,800 volunteered for the study called ACTIVE - short for Advanced (Cognitive) Training for Independent and Vital Elderly. Most studied when they were more than 70 years old.
The volunteers took one of several short training classes meant to help them keep their mental abilities. One class trained participants in skills including how to remember word lists. Another group trained in reasoning. A third group received help with speed-of-processing - speed of receiving and understanding information. A fourth group - the control group did not get any training.
Earlier results had established that the training helped the participants for up to five years. Now, lead study writer George Rebok says, the research showed most of the training remained effective a full ten years later.
Professor Rebok and his team found that the people trained in reasoning and speed-of-processing did better on tests than the control group.
"We are wondering whether those effects which endured over time would still be there ten years following the training, and in fact, that's exactly what we found."
The effect on memory, however, seemed not to last as long. Still, the old people in any of the three classes generally reported less difficulty in performing daily activities than the control group. The total training time for the older people was between 10 and 15 hours.
小題1:Which statement is true according to the text？
A．This kind of training can only have effect on people for a few years。
B．The people were trained during a period of ten years.
C．All the people who were studied were more than 70 years old.
D．The second group were trained how to remember word lists.
小題2:What can be inferred from the passage？
A．There were four groups being trained.
B．The old people trained can remember words better.
C．The second and third group improved their skills better than the first one.
D．The research showed that the effect of the training could absolutely last 10 years.
小題3:What’s the main idea of the fourth paragragh?
A．What was the meaning of the research?
B．How was the research conducted?
C．Why was the mental training effective?
D．How long did the research last?
小題4:What is the best title of the passage？
A．Mental Training Helped Elderly Stay Sharp for Years
B．How to improve our mental health
C．Four groups of old people were trained mentally.
D． The result of a ten-year research

Recently a study, led by Pedro Hallal of the Federal University, suggests that nearly a third of adults, 31%, are not getting enough exercise. That rates of exercise have declined is hardly a new discovery. Since the beginning of the industrial revolution, technology and economic growth have helped to create a world in which taking exercise is more and more an option rather than a necessity. But only recently have enough good data been collected from enough places to carry out the sort of analysis Dr Hallal and his colleagues have engaged in.
There are common themes in different places. Unsurprisingly, people in rich countries are less active than those in poor ones, and old people are less active than young ones. Less obviously, women tend to exercise less than men—34% are inactive, compared with 28% of men. But there are exceptions. The women of Croatia, Finland, Iraq and Luxembourg, for example, move more than their male countrymen.
Malta wins the race for most slothful country, with 72% of adults getting too little exercise, and Swaziland and Saudi Arabia are in close behind, with 69%. In Bangladesh, just 5% of adults fail to exercise enough. Surprisingly, six Americans in ten are active enough according to Dr Hallal’s study, compared with fewer than four in ten British.
These high rates of inactivity are worrying. Human beings seem to have evolved(進化) to benefit from exercise while deliberately avoiding it whenever they can. In a state of nature it would be impossible to live a life that did not provide enough of it. But that is no longer the case. Actually lack of enough activity these days has nearly the same effect on life span(壽命) as smoking.
小題1:We may learn from Paragraph 1 that_________.
A．the decline of exercise rates is newly discovered
B．the study suggests 31% of female adults get too little exercise
C．the good enough data has been collected from only one country
D．the industrial revolution has changed the way people live to some degree
小題2:According to the study, women of Luxembourg_________. 
A．have little time to exercise
B．hate to get regular exercise
C．take more exercise to lose weight
D．exercise more than men in their country
小題3:The underlined word “slothful” in Paragraph 3 most probably means_________.
A．powerfulB．richC．lazyD．unpopular
小題4:What can be the best title for the text?
A．Worldwide Lack of Enough Exercise
B．New Health Discovery
C．Evolvement of Human Beings
D．Benefits of Taking Exercise

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.”
小題1:From this passage we know that ________.

小題3:In Hart’s first 20-week workshop, people there can ________.
A．meet their enemies
B．change their attitudes
C．enjoy the professor’s teaching

Putting in water fountains(飲水器) 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(飲料) 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.
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.
小題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(授權(quán)) by a school
小題2:What do we know about the survey from the text?
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.
小題3:The fifth paragraph is mainly about __________.
A．the technique used in the surveyB．the benefits of the survey
C．the process of the surveyD．the result of the survey
小題4:What can be learned from the last paragraph?
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.
D．Why students drinking more get less pounds will be clear soon.

In today's fast-paced (快節(jié)奏) society, few people take time to enjoy the midday meal．Most of us just rush right through it. We grab a quick salad, or buy a sandwich and eat at our computers, Sometimes, if there is a deadline around the corner, we just skip lunch．
The development of technology hasn't done our eating habits much good either．We are constantly distracted by e-mail, social media, and 24 - hour news．Even when we do sit down for lunch, we are more connected to our hand - held electronic devices．
Long working hours can cause all kinds of health problems, and many developed countries have put in place labor laws specifically regarding the lunch break．These laws give employees the right to take a break during a long work shift, but it's up to them whether they do so or not．
Frank Partnoy, a former Wall Street trader, says that employers should encourage workers to take time off for lunch．This is because long lunch breaks can benefit both individuals and society.
Writing in The Guardian, Partnoy says that one obvious reason to take a lunch break is to slow down and gain some perspective（認識）． A break from work allows us to think strategically and outside the box．It also puts our daily tasks into a broader context（背景）．
What we eat at lunch is also important．In Partnoy' s opinion, a fast food lunch is more harmful than not having lunch at all．  And it's not just about calories and unhealthy food．Recent studies show that fast food also has negative effects on how we think．
However, if we sit down at a proper restaurant and chat leisurely with colleagues, we are more likely to slow down, something that hardly can be achieved in a noisy and over — packed fast food chain．
Despite these benefits, some employees might still be unwilling to take time off for lunch．Partnoy's suggestion? Make skipping lunch difficult: Employers could ask workers to fill out a form stating their reasons for skipping the meal．
小題1:What does the underlined phrase "skip lunch" mean in the first paragraph?
A．have a quick lunchB．don't have lunch
C．work while having lunchD．take a lunch break
小題2:Which of the following is true according to the text?
A．Modern technology results in good diet habits．
B．Electronic devices make our life comfortable．
C．Many people are too busy to have a good lunch．
D．Laws have passed to make workers have lunch．
小題3:According to Frank Partnoy, long lunch breaks            .
A．a(chǎn)re time for the workers to relax their mind
B．make the employees work longer hours
C．a(chǎn)re for employees to have a quick lunch
D．make the workers eat a proper lunch at home
小題4:In Partnoy's opinion, a fast food lunch                .
A．saves a lot of time for a rest
B．a(chǎn)ffects people's way of thinking
C．is better than having no lunch
D．makes workers sit down and think
小題5:What might be the author's purpose in writing the text?
A．To warn us not to eat fast food．
B．To introduce Frank Partnoy's opinion．
C．To encourage us to work more efficiently．
D．To show the importance of a proper lunch．
