Just five minutes of exercise a day outdoors can improve mental health, according to a study.
Researchers from the University of Essex, UK have found that as little as five minutes of a “green activity” such as walking, gardening, cycling or farming could help to improve mood and increase self-esteem (自信).
Many studies have shown that outdoor exercise can reduce the risk of mental illness and improve a sense of well-being, but the new study, led by Jules Pretty and Jo Barton, was the first to determine how much time needed to be spent on green exercise for the benefits to show.
Barton and Pretty looked at data from 1,252 people of different ages, genders (性別) and mental health status (情況) taken from 10 studies in Britain.
They analyzed their different outdoor activities including walking, gardening, cycling, fishing, boating, horse-riding and farming in locations such as a park, garden or nature trail (路徑).
They found that the mental health changes were seen after just five minutes. With longer periods of time exercising in a green environment, the positive effects were more apparent.
Looking at men and women of different ages, the researchers found the health changes were particularly strong in the young and the mentally ill.
Green and blue
A bigger effect was seen with exercise in an area that also contained water – such as a lake or river.
“This is because historically we are drawn to water to survive and it is in our genetic (遺傳的) make-up to be at one with nature,” the researchers wrote in their report.
Pretty said those who were generally inactive, or stressed, or with mental illness would probably benefit the most from “green exercise”.
“Employers, for example, could encourage staff in stressful workplaces to take a short walk at lunchtime in the nearest park to improve mental health.”
He also said exercise programs outdoors could benefit youth offenders.
小題1:How is the study this article refers to different from other studies?
A．It involved more people.
B．It took longer to finish the research.
C．It determined the exact amount of time needed.
D．It was led by just two researchers.
小題2: What can we conclude from the findings of the study?
A．Just five minutes of “green exercise” daily can help improve mental health.
B．Gardeners and farmers do not need “green exercise”.
C．Walking in a park with a lake will weaken the effect.
D．“Green exercise” is not suitable for the mentally ill.
小題3:. According to Pretty, _______ would probably benefit the most from “green exercise”.
A．stressed, inactive peopleB．office workers
C．youth offenders D．women and children
小題4: What is the main problem discussed in this article?

A cheap drug that can stop bleeding in people recently injured in an accident could potentially save the lives of tens of thousands worldwide, a new study says.
Researchers studied the effects of tranexamic acid （凝血酸）, or TXA, in more than 10,000 injured people in 40 countries who received the drug within 8 hours of being injured. The study was published in the medical journal Lancet. Doctors found that patients who got TXA had a 15percent lower chance of dying from hemorrhage than those who didn’t get it . They also had a 10 percent lower chance of dying from any other cause, including organ failure and a head injury. The study was paid for by the British government.
The drug is commonly used in wealthy countries during elective surgeries(外科手術(shù)) to stop bleeding , but isn’t used for accident victims. TXA is off-patent and made by many companies. It costs about $4.5 per gram, and a typical dose is two grams. It is usually given via an injection（注射） and would be relatively easy to introduce, even in poor countries, experts said.
Previous tests of the drug regarded its use in elective surgeries, such as heart operations, but this was the first study to test the drug on accident victims. Doctors were worried it might increase side effects such as blood clots （凝塊）in the heart and lungs, strokes, or heart attacks. There was no evidence of that in the Lancet study, though the authors said it was possible they might have missed some of these incidents.
For people between 5 and 45, accidents are the second leading cause of death worldwide after AIDS, and about 600,000 injured patients bleed to death every year. Experts estimated that if TXA were readily available, between 70,000 and 100,000 lives a year could be saved. Though the drug wasn’t tested on children , experts said it would almost certainly work with them as well.
小題1:The underlined word” hemorrhage” in Paragraph 2 probably means ________
A．serious illnessB．heart diseaseC．heavy bleedingD．lack of drug
小題2:What can we learn about TXA from the passage?
A．It can only be made in EnglandB．It was only used in operations before
C．It is a patented drugD．It is mainly used in poor countries
小題3:Doctors were worried about using TXA because ________
A．a(chǎn) lot of patients died unexpectedly after using it
B．it has no treatment effect on patients
C．it can cause blood clots or stroke
D．they hadn’t used it on accident victims before
小題4: What do we know from the last paragraph?
A．It is a pity that TXA wasn’t widely used on injured patients before
B．Tests have proved that TXA can be used on children
C．People between 5 and 45 should be injected with TXA every year
D．Accidents are the first leading cause of death worldwide.

Chocolate is good for your heart, skin and brain. Usually, people think that chocolate is bad for their health. They describe chocolate as “something to die for” or say “death by chocolate”．Now they should bite their tongues! Evidence(證據(jù)) is showing that some kinds of chocolate are actually good for you in the following ways:
A happier heart
Scientists at Harvard University recently examined 136 studies on cocoa—the main ingredient in chocolate and found that it does seem to strengthen the heart．Studies have shown heart benefits from increased blood flow．These benefits are the result of cocoa’s chemicals, which seem to prevent both cell damage and inflammation(炎癥)．
Better blood pressure
If yours is high, chocolate may help．Jeffrey Blumberg from Tufts University recently found that people with high blood pressure who ate 3.5 ounces of dark chocolate per day for two weeks saw their blood pressure drop quickly．
Muscle magic
Chocolate milk may help you recover after a hard workout(鍛煉)．In a small study at Indiana University, people who drank chocolate milk between workouts did better on a tiredness test than those who had some sports drinks．
Better for your skin．German researchers gave 24 women a half-cup of special cocoa every day．After three months, the women’s skin was moister(滑潤(rùn)的)and smoother．The research shows that chocolate helps protect and increase blood flow to the skin, improving its appearance．
Brain gains
It sounds almost too good to be true, but research suggests that chocolate may improve your memory, attention span, reaction time, and problem-solving by increasing blood flow to the brain．
小題1:Which of the following is wrong?

A good night’s sleep in the early years of life could be very important in preventing a child becoming obese, say scientists. Babies and pre-school children who sleep for less than ten hours a night are more likely to be overweight when they are older, research has found. Experts believe that those who do not get enough sleep are more likely to feel hungry and want more calorie-rich food during the day.
Former research has linked sleeping with obesity in adults and teenagers, but this is one of the first to look at very young children. Researchers from the Universities of Washington and California looked at the sleeping habits of almost 1,000 children under the age of five. They found those who had less than ten hours’ sleep were twice as likely to be overweight five years later.
Childhood obesity has doubled over the past 10 years. A quarter of secondary school pupils are now judged to be so overweight that their health is in danger. Experts believe sleep, or lack（缺乏）of it, could be a major cause of this. On average children are sleeping for an hour less than they did 30 years ago. Last year Chinese researchers looked at more than 5,000 youngsters and found that those who were able to catch up on （補(bǔ)充）sleep at the weekend were far less likely to get body weight problems. Scientists have also found a link between lack of sleep and diabetes（糖尿�。�. Last year Canadian researchers discovered those who did not get seven or eight hours’ sleep a night were two and a half times more likely to become sick.
小題1:The underlined word “obese” in the first paragraph may mean       .
A．quite protective B．very sad
C．very fatD．quite young
小題2:According to Chinese researchers, if a person who lacks sleep can get more sleep during weekends,       .
A．he won’t get hungry easilyB．he will feel tired all the time
C．there will be little chance of him becoming fat
D．it will be very hard for him to fall asleep at night
小題3:From the passage we know       .
A．too little sleep will result in illness besides obesity
B．in the past people didn’t connect sleep with weight
C．fat children must have slept less than 10 hours five years ago
D．most children are unhealthy because of little sleep
小題4:What would be the best title of the passage?
A．A good night’s sleep helps the development of kids’ brain!
B．Ten hours’ sleep prevents overweight in kids!
C．Children are sleeping much less nowadays!
D．More teenagers get weight problems!
小題5:Where can you most probably read this passage?
A．In the latest news.B．In a children’s book.
C．In a health magazine.D．In a scientist’s diary.

More than 10 years ago, it was difficult to buy a tasty pineapple. The fruits that made it to the UK were green on the outside and, more often than not, hard with an unpleasant taste within. Then in 1966, the Del Monte Gold pineapple produced in Hawaii first hit our shelves.
The new type of pineapple looked more yellowy-gold than green. It was slightly softer on the outside and had a lot of juice inside. But the most important thing about this new type of pineapple was that it was twice as sweet as the hit-and-miss pineapples we had known. In no time, the Del Monte Gold took the market by storm, rapidly becoming the world’s best-selling pineapple variety, and delivering natural levels of sweetness in the mouth, up until then only found in tinned pineapple.
In nutrition it was all good news too. This nice tasting pineapple contained four times more vitamin C than the old green variety. Nutritionists said that it was not only full of vitamins, but also good against some diseases. People were understandably eager to be able to buy this wonderful fruit. The new type of pineapple was selling fast, and the Del Monte Gold pineapple rapidly became a fixture in the shopping basket of the healthy eater.
Seeing the growing market for its winning pineapple, Del Monte tried to keep market to itself. But other fruit companies developed similar pineapples. Del Monte turned to law for help, but failed. Those companies argued successfully that Del Monte’s attempts to keep the golden pineapple for itself were just a way to knock them out of the market.
小題1:We learn from the text that the new type of pineapple is __________.
A．green outside and sweet insideB． good-looking outside and soft inside
C．yellowy-gold outside and hard insideD．a(chǎn) little soft outside and sweet inside
小題2:Why was the new type of pineapple selling well?
A．It was rich in nutrition and tasted nice.B．It was less sweet and good for health.
C．It was developed by Del Monte.D．It was used as medicine.
小題3:The underlined word “fixture” in Paragraph 3 probably refers to something _________.
A．that people enjoy eatingB．that is always present
C．that is difficult to getD．that people use as a gift
小題4: We learn from the last paragraph that Del Monte _________.
A．slowed other companies to develop pineapples
B．succeeded in keeping the pineapple for itself
C．tried hard to control the pineapple market
D．planned to help the other companies

Motherhood may make women smarter and may help prevent dementia （癡呆） in old age by bathing the brain in protective hormones （荷爾蒙） , U.S. researchers reported on Thursday.
Tests on rats show that those who raise two or more litters of pups do considerably better in tests of memory and skills than rats who have no babies, and their brains show changes that suggest they may be protected against diseases such as Alzheimer’s （早老癡呆癥）. University of Richmond psychology professor Craig Kinsley believes his findings will translate into humans.
“Our research shows that the hormones of pregnancy are protecting the brain, including estrogen （雌激素）, which we know has many neuroprotective （保護(hù)神經(jīng)的） effects,” Kinsley said.
“It’s rat data but humans are mammals just like these animals are mammals,” he added in a telephone interview. “They go through pregnancy and hormonal changes.”
Kinsley said he hoped public health officials and researchers will look to see if having had children protects a woman from Alzheimer’s and other forms of age-related brain decline.
“When people think about pregnancy, they think about what happens to babies and the mother from the neck down,” said Kinsley, who presented his findings to the annual meeting of the Society of Neuroscience in Orlando, Florida.
“They do not realize that hormones are washing on the brain. If you look at female animals who have never gone through pregnancy, they act differently toward young. But if she goes through pregnancy, she will sacrifice her life for her infant—that is a great change in her behavior that showed in genetic alterations （改變） to the brain.”
小題1: How do scientists know “Motherhood may make women smarter”?
A．Some researchers have told them.
B．Many women say so.
C．They know it by experimenting on rats.
D．They know it through their own experience.
小題2: What does the phrase “l(fā)itters of pups” mean in the second paragraph?
A．Baby rats.B．Animals. C．Old rats. D．Grown-up rats.
小題3: What can protect the brain of a woman according to the passage?
A．Estrogen.B．The hormones of pregnancy.
C．More exercise.D．Taking care of children.
小題4:“It’s rat data but humans are mammals just like these animals are mammals.” What does the sentence suggest?
A．The experiments on the rats have nothing to do with humans.
B．The experiments on the rats are very important for animals.
C．The experiments on the rats are much the same on humans.
D．The experiments on the rats are much the same on other animals.

Americans this year will swallow 15,000 tons of aspirin, one of the safest and most effective drugs invented by man. The most popular medicine in the world today, it is an effective pain reliever. Its bad effects are relatively mild and it is cheap.
For millions of people suffering from arthritis(關(guān)節(jié)炎), it is the only thing that works. Aspirin, in short, is truly the 20th-century wonder drug. It is also the second largest suicide drug and is the leading cause of poisoning among children. It has side effects that, although relatively mild, are largely unrecognized among users.?
Although aspirin was first sold by a German company in 1899, it has been around much longer than that. Hippocrates, in ancient Greece, understood the medical value of the leaves and tree bark which today are known to contain salicylates(水楊酸堿), the chemical in aspirin. During the 19th century, there was a great deal of experimentation in Europe with this chemical, and it led to the introduction of aspirin. By 1915, aspirin tablets were available in the United States.?
A small quantity of aspirin (two five-grain tablets) relieves pain and inflammation(炎癥). It also reduces fever by interfering with some of the body’s reactions.

There's a lot of discussion these days about healthy kids. People who care (parents, doctors, teachers, and others) want to know how to help kids be more healthy.
Being healthy is a way of saying a person eats well, gets a lot of physical activity (exercise), and has a healthy weight. If you're healthy, your body works well, feels good, and can do all the things you want to do. Here are five rules to live by, if you're a kid who wants to be healthy.
Eat a Variety of Foods, Especially Fruits and Vegetables. You may have a favorite food, but the best choice is to eat a variety. If you eat different foods, you're more likely to get the nutrients(營(yíng)養(yǎng)) your body needs. Taste new foods and old ones you haven't tried for a while. Get at least five servings of fruits and vegetables a day — two fruits and three vegetables.
Drink Water and Milk Most Often. When you're really thirsty, cold water is the No. 1 for you. Kids need calcium（鈣）to build strong bones, and milk is a great source of this mineral. How much do kids need? Aim for 3 cups of milk per day. You can mix it up by having milk and some other calcium-rich dairy foods .
Be Active.One job you have as a kid — and it's a fun one — is that you get to figure out which activities you like best. Not everyone loves baseball or soccer. Ask your parents to help you do your favorite activities regularly. Find ways to be active every day. You might even write down a list of fun stuff to do, so you can refer to it when your mom or dad says it's time to stop watching TV or playing computer games!
小題1: What’s the best title for this passage?
A．Do Your Favorite Activities RegularlyB．Eat More Fruits and Vegetables Every Day
C．Drink Water and Milk When You Are ThirstyD．Tips on How to Keep Healthy
小題2: Which of the following can’t show a kid is healthy?
A．Eating wellB．Having too much sleep
C．Having a healthy weightD．Getting a lot of physical exercise
小題3: The best way to get enough nutrients for your body is ________.
A．to drink milk every dayB．to eat what you haven’t eaten before
C．to eat all kinds of foodsD．to eat fruits and vegetables instead of grains
小題4:The underlined words “this material” in the fourth paragraph refer to _________.
A．calciumB．calcium-rich dairy foodC．milkD．nutrients
