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

"Children should not be left unsupervised (無(wú)人監(jiān)督的) to play with a dog." say experts in this week's British Medical Journal. Their advice is part of a review aimed at doctors who deal with dog bites.
"Dog bites and maulings are a worldwide problem, particularly in children." write Marina Morgan and John Palmer. Every year 250,000 people who have been bitten by dogs attend minor injuries and emergency units in the United Kingdom, and half of all children are reportedly bitten by dogs at some time, boys more than girls.
Accurate death figures are difficult to obtain, but in the past five years, two to three cases a year have made news headlines.
Based on the latest medical evidence, they advise doctors how to examine and treat a patient presenting with a dog bite. They discuss the risk of infection and when to refer to specialist care. For travelers bitten abroad, they suggest assessing the risk of rabies(狂犬病).
In terms of prevention, they suggest that children should be taught to treat dogs with respect, avoid direct eye contact, and not tease them. They should be taught not to approach an unfamiliar dog; play with any dog unless under close supervision; run or scream in the presence of a dog; pet a dog without first letting it sniff you; or disturb a dog that is eating, sleeping, or caring for its babies.
"Dog owners also need to change their behavior", says Rachel Besser, a children's doctor and lifetime dog owner, in an article.
"It is clear that not all dog owners appreciate that children should not be left unsupervised with a dog", she says. Just as some parents are obliged to take parenting classes, she would like to see compulsive classes for expectant dog owners to teach them about the responsibilities of dog ownership. Educational programs are also needed to teach children about some precautionary （預(yù)防的) behaviors around dogs.
Finally, she would like to see animal doctors advising dog owners about bite prevention, and doctors promoting bite prevention when treating patients who have been bitten by dogs.   
小題1:Dog biting is a problem which _____.
A．only happens to a few childrenB．should be paid attention to
C．only boys may meet withD．has made news headlines
小題2:The underlined word "they" in Paragraph 4 refers to "________" .
A. doctors         B. parents            C. experts            D dog owners
小題3:To avoid dog bites, a child should be taught to_____.
A．have direct eye contact B．a(chǎn)pproach an unfamiliar dog
C．run or scream in the presence of a dogD．leave a dog feeding itself
小題4:What are Rachel Besser's words mainly about?
A．It's necessary to teach children how to raise dogs.
B．Children should be taught not to play with dogs.
C．All the dog owners would like to attend classes on caring for dogs.
D．Some dog owners would like children to be left unsupervised with a dog.
小題5:Which of the following can be the best title for the passage?
A．Dogs, Dangerous To Children

Modern science suggests that a healthy lifestyle matters much to how long you can live and how well you live. Here are some tips for you to form a healthy lifestyle.
Keep a scientific diet. Keep in mind that sugar can be removed from our diet completely. Over intake of sugar is one of the main reasons for getting fat. Over intake of protein or fat and low intake of fiber can also lead to getting fat. We need only a few grams of protein every day to keep our body in order. Like rain to crops, not the more the better.
Be always in a good mood. There is a relationship between the mood and health. A good mood keeps you in high spirits. Thanks to the Internet, we can enjoy and learn much without going out. Take a look at some online shops and pick up some bargains, enjoy music and movies and chat with some good friends. Just keep happy.
Enough sleep. Two studies show the reasons why teens and adults don’t have enough sleep. With teens, a major reason is mobile phone use; with adults, it’s work. Meanwhile, a third study of young children shows that a lack of sleep in early life may lead to serious problems in future. Everyone needs at least 8-hour sleep to recover from tiredness and the hurt caused by hard work in the daytime.
Proper exercise. Do exercise to keep away from fatness. Because of the quick pace of modern life, you don’t have time to do exercise every day, but at least three times a week and 45 minutes each time.
小題1:The author wrote the passage to _______.

Even a small reduction in salt in the diet can be a big help to the heart. A new study used a computer model to predict how just three grams less a day would affect heart disease in the United States.
The result: thirteen percent fewer heart attacks. Eight percent fewer strokes. Four percent fewer deaths. Eleven percent fewer new cases of heart disease. And two hundred forty billion dollars in health care savings.
Researchers found it could prevent one hundred thousand heart attacks and ninety-two thousand deaths every year.
The study is in the New England Journal of Medicine. Kirsten, at the University of California, was the lead author. She says people would not even notice a difference in taste with three grams, or one-half teaspoon, less salt per day. The team also included researchers at Stanford and Columbia University.
Each gram of salt contains four hundred milligrams of sodium, which is how foods may list their salt content.
The government says the average American man eats ten grams of salt a day. The American Heart Association advises no more than three grams for healthy people. It says salt in the American diet has increased fifty percent since the nineteen seventies, while blood pressures have also risen. Less salt can mean a lower blood pressure.
New York City Mayor Michael Bloomberg is leading an effort called the National Salt Reduction Initiative. The idea is to put pressure on food companies and restaurants.
Mayor Bloomberg has already succeeded in other areas, like requiring fast food places in the city to list calorie information. Now a study by the Seattle Children's Research Institute shows how that idea can influence what parents order for their children.
Ninety-nine parents of three to six year olds took part. Half had McDonald's menus clearly showing how many calories were in each food. The other half got menus without the calorie information.
小題1: How many heart attacks will occur in the US every year？ 
A．nearly 800,000.B．24,000.
C．100,000.D．92,000.
小題2:We can learn from the passage that         .  
A．Americans ate no more than 5 grams of salt per day in the 1970s
B．the American Heart Association suggest less than 3 grams of salt every day
C．a(chǎn) reduction in salt in the diet helps lower blood pressure
D．a(chǎn)ll the heart diseases result from eating more salt
小題3:The National Salt Reduction Initiative aims to         . 
A．a(chǎn)dvise Americans to eat less salt

A new study has been carried to test the role of story telling in lowering blood pressure．Dr．Thomas Houston, a professor of the University of Massachusetts Medical School, led a group of scientists that investigated how pre-recorded videos of hypertension （高血壓） patients' talking about their medical histories helped another group of patients with high blood pressure to control their condition over several months．
Houston was surprised by their studies that suggested that communication can be a powerful tool in medicine．They showed that those who had had similar experiences, when talking to someone with a similar background, could help change their behavior to become healthier．Hypertension is difficult to control, since it is dependent on diet, exercise and mental state．Medical treatments with drugs, and lifestyle therapies（療法） have been relatively ineffective because people find it hard to follow those medical requirements．
In the test, his team carefully chose their story-tellers from 230 members of a patients' community with whom they could most easily relate．Next, they divided their study population into two groups．One received three interactive （互動(dòng)） DVDs containing the tellers' stories of their experiences in living with and treating their hypertension．The other were given educational discs on an unrelated health topic．The study volunteers reported that they had listened to the DVDs, and after three months, those who heard the stories of the hypertensive patients lowered their blood pressure．
While the study did not address how the story-telling influenced the patients' behavior, Houston suspects that watching patients of similar backgrounds who had a similar medical experience helped to motivate them to seek medical help to their hypertension．They found that after six months the difference in blood pressure between those who watched the story-tellers and those who observed the unrelated videos remained, suggesting that the story-telling continued to have an effect．
小題1:We can learn from the text that the pre-recorded videos _________．
A．tell medical histories of hypertension patients
B．introduce some medical treatments of hypertension
C．introduce a good lifestyle for hypertensive patients
D．tell scientific discoveries of the scientist group
小題2:Houston was surprised to find that _______．
A．hypertension is really difficult to control
B．communication has some medical effects
C．medical treatments have no effect at all
D．people don't follow the medical requirements
小題3:Which of the following is true about the study?
A．The scientists chose 230 patients from a hospital．
B．Both the groups used the same videos about health topic．
C．The two groups lowered blood pressure in different degrees．
D．The story-tellers were hypertension patients as well．
小題4:Which of the following could be the best title of the text?

Health officials issued a waring over common energy-saving l一ghtbulbs(燈泡) after research showed some types could potentially harm the skin and may even raise the risk of cancer.
A study by the Health Protection Agency (HPA) found that some eco-friendly lightbuulbs release levels of ultraviolet (UV) (紫外線) radiation that are above recognized safety limits. The agency urged people who work with lamps nearby to avoid spending more than one hour within a foot of the eco-friendly bulbs. The warning was directed at those using desk lamps for long periods, such as jewellery makers, and others who might have lights close to their faces, such as car mechanics.
John O’Hagan, a scientist at the HPA’s centre for radiation, chemical and environmental dangers, began tests on the ligthbulbs after patient groups raised concern about them. Among the groups were patients with a skin disease called lupus, which makes people highly sensitive to light.
The tests measured UV light from the lamps and found the highest levels of UV radiation, measured 2cm from the lightbulbs, were equivalent to being outside in direct sunlight in the summer. The most immediate risk from the lightbulbs is a reddening of the skin similar to sunburn, but there is also a small increased risk of skin cancer associated with this, again similar to that of sunburn.
The risk of health problems from the lightbulbs was not so high that people should remove them from their homes. People are advised to avoid using open lightbulbs for long close work until the problem is sorted out. It has confirmed that the government will not be reviewing its strategy on introducing energy efficient lightbulbs.
小題1:The underlined word “equivalent” in paragraph 4  most probably means ______.
A．equalB．vitalC．relevantD．harmful
小題2:In order not to be harmed by the UV radiation from some lightbulbs, people should ______.
A．stop using eco-friendly lightbulbs at home
B．a(chǎn)void using open lightbulbs for long close work
C．take care not to expose their skin to direct sunlight
D．urge the government to ban the use of lightbulbs
小題3:In the next part, the author would most probably further explain _____.
A．why people needn’t remove the lightbulbs from their homes
B．how researchers have planned to sort out the problem
C．how the government has responded to HPA’s discovery
D．how long people should work close to the open lightbulbs
小題4:We can learn from the passage that ____.
A．health officials issued a warning over common lightbulbs.
B．jewellery makers should avoid working with the eco-friendly bulbs for more than one hour
C．John O’Hagan did tests on the lightbulbs with some patients
D．people are advised to avoid using open lightbulbs for long close work

  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．Physical well-being. B．Outdoor exercise.
C．Mental illness. D．Harmony with nature.
