Is going on holiday of any benefit? New research shows that going on holiday makes you not only feel good while you’re there but also gain the health benefits for months.

Jetting off to destinations such as the Maldives cuts your blood pressure, helps you sleep better and bounce back from stress. The benefits last at least a fortnight longer than the vacation and can be felt for months in some cases where it is claimed. Experts say workers should always take their holiday entitlement (权利) each year, but as ‘many as one in three don’t.

The study compared key health markers in holidaymakers visiting Thailand, Peru or the Maldives, with those in people who stayed at home and continued working. The average blood pressure of those on holiday dropped by six percent while the workers saw their blood pressure rise by two percent over the same period. The sleep quality of holidaymakers improved by 17 percent while that of the non—holidaymakers deteriorated by 14 percent.

The study also found the ability of vacationers to recover from stress, known as the stress-resilience test, improved by 29 percent. There was a 71 percent fall in stress-resilience scores among workers. Tests showed fallen blood glucose (葡萄糖) levels, reduced risk of diabetes (糖尿病), trimmer waistlines and improved mood and energy levels, with the effects sustained for at least two weeks after returning home.

The Holiday Health Experiment was conducted by tour operator Kuoni and Nuffield Health, the UK’s largest healthcare charity.

The research from the U.S. Centers for Disease Control and Prevention shows that food allergies ( 过 敏 ) in children have increased about 50 percent. Common symptoms　 of allergic responses include itchy mouth, throat tightening, and difficulties in breathing.

Food allergy is a medical condition of exposure to certain foods. It occurs when the immune system attacks the protein in food that in normal cases is harmless. According to reports, more than 170 foods cause allergic reactions. The major food allergens are in eggs, milk, peanuts, wheat, soy, fish, tree nuts, and crustacean shellfish.

There are several reasons behind the rise in food allergies. The food being produced these days is high in sugar, unhealthy fats, genetically modifies and some food farms have　 pesticides ( 农 药 ) and other food have been injected drugs. All this can have a negative impact on our microbiome (微生物群), which is the basis of good health and immunity.

In a study comparing two children, a 15-year-old who lived in urban Italy and a 14-year-old child from rural Africa, it clearly showed a significant difference in the diversity of bacteria in their guts. The reason lies in their diet. The child from rural Africa has his diet low　 in fat and rich in plant-based foods which are grown and harvested locally by villagers. In contrast, the Italian kid’s diet was rich in animal protein, sugar then low in fiber. Ultimately, the microbiome of the kid from Italy was less than that of the kid from Africa.

Besides, the so-called ‘hygiene hypothesis’ suggests that decreased exposure to microbes in early life can lead to an increased chance of allergies in later life, because of individuals not having built up immunity at a young age.

Yet another reason for the explosion in allergies may be environmental changes. The environment has seen a rise in temperature and is estimated that in the coming decades the temperature could rise even further by 10 degrees. As a result of this warm climate, the growing seasons will be longer, increasing allergen count thus making allergies even worse. According to scientists, climate change is a contributing factor that needs immediate attention.

Dr. R. Sharon, researcher of Allergy and Asthma Research Centre at Stanford University, believes the cause of allergies will ultimately come down to a combination of many factors.

Food allergies have no cure but can be managed by avoiding food that brings the　 reactions. Scientists are studying food allergies medical methods for general use. They are all trying to actively understand a certain part of the puzzle when it comes to allergies.

1.What can we learn from the passage?

A.Scientists have found an effective method to solve food allergies.

B.There could be many reasons that combine to lead to food allergies.

C.Environmental changes are the most important reason for food allergies.

D.To decrease children’s allergies, we should make them eat less every day.

2.In paragraph 4, the two children are mentioned to show that

A.pesticides have bad effects on people’s food

B.a person’s daily diet can affect his microbiome

C.food allergies have no cure but can be avoided

D.climate　 change is another factor for food allergies

3.What is the main purpose of this passage?

A.To explain the causes of food allergies.

B.To stress the influences of food allergies.

C.To introduce the solutions to food allergies.

D.To tell people the symptoms of food allergies.

4.What’s the author’s attitude to the treatment of food allergies?

A.Indifferent. B.Positive.

C.Doubtful. D.Critical.

Research shows that humans switch from selfish to unselfish behaviors when they are watched. Do you?

A picture of a set of eyes on a computer screen can cause a change in the way people act. Even images of eyes on a charity donation, collection box encourage people to be unselfish, because people put more money in a collection box that has a picture of eyes on it than they do when a flower symbol is on the box.

Biology in Germany and Bettina Rockenbach of the University of Berlin,

the authors of a new study, found that people act better when they are being

watched because they feel they will be rewarded for good behaviour.

Their report also referred to other research showing that this response of

behaving well when watched is somehow coded into humans and

people respond this way unconsciously, or without realising it.

It is not just humans that act unselfishly when they are being watched.

A fish called the grooming fish cleans other fish. When other fish are

around, it is gentler. When no other fish are around, however, the grooming fish bites chunks from the fish it is supposed to be cleaning.

The researchers suggest that the best way to get people to behave in the correct way is to make them feel watched. This could be the reason for the success of a famous American army poster. On it was a picture of an elderly man staring fiercely and pointing, it appeared, to the person who was looking at the poster. Under the picture was the caption ‘I Want You’. It encouraged hundreds of thousands of young American men to join the army during the Second World War to fight the Germans and Japanese.

1. According to the report, why does a person behave better when he feels he is being watched?

A. He does not want to be shamed by others.

B. He needs to show he is a good person.

C. He desires others to like him more.

D. He feels he will receive some social reward.

2. The underlined word ‘coded’ (paragraph 3) is closest in meaning to______.

A. hidden            B. programmed     C. forgotten         D. leaned

3. What is the text mainly about?

A. It describes changed behaviour when observed.

B. It details ways to control people's behaviour.

C. It tells how to make people work harder.

D. It discusses different advertising methods.

4. According to the text, which of the following statements is True?

A. People pretend to behave better when they are watched.

B. Fish bite other fish in a fish tank when they are alone.

C. People donate more money when they feel they are watched.

D. Soldiers fought better during World War II because of a poster.

5. Where would the study described in the text most likely be found?

A. In a newspaper.                     B. In a scientific journal.

C. In an advertising magazine.           D. In a science textbook.

Race walking shares many fitness benefits with running, research shows, while most likely contributing to fewer injuries. It does, however, have its own problem.

Race walkers are conditioned athletes. The longest track and field event at the Summer Olympics is the 50-kilometer race walk, which is about five miles longer than the marathon. But the sport’s rules require that a race walker’s knees stay straight through most of the leg swing and one foot remain in contact (接触) with the ground at all times. It’s this strange form that makes race walking such an attractive activity, however, says Jaclyn Norberg, an assistant professor of exercise science at Salem State University in Salem, Mass.

Like running, race walking is physically demanding, she says, According to most calculations, race walkers moving at a pace of six miles per hour would burn about 800 calories(卡路里) per hour, which is approximately twice as many as they would burn walking, although fewer than running, which would probably burn about 1,000 or more calories per hour.

However, race walking does not pound the body as much as running does, Dr. Norberg says. According to her research, runners hit the ground with as much as four times their body weight per step, while race walkers, who do not leave the ground, create only about 1.4 times their body weight with each step.

As a result, she says, some of the injuries associated with running, such as runner’s knee, are uncommon among race walkers. But the sport’s strange form does place considerable stress on the ankles and hips, so people with a history of such injuries might want to be cautious in adopting the sport. In fact, anyone wishing to try race walking should probably first consult a coach or experienced racer to learn proper technique, she says. It takes some practice.

1.Why are race walkers conditioned athletes?

A.They must run long distances.

B.They are qualified for the marathon.

C.They have to follow special rules.

D.They are good at swinging their legs.

2.What advantage does race walking have over running?

A.It’s more popular at the Olympics.

B.It’s less challenging physically.

C.It’s more effective in body building.

D.It’s less likely to cause knee injuries.

3.What is Dr. Norberg’s suggestion for someone trying race walking?

A.Getting experts’ opinions.

B.Having a medical checkup.

C.Hiring an experienced coach.

D.Doing regular exercises.

4.Which word best describes the author’s attitude to race walking?

A.Skeptical. B.Objective.

C.Tolerant. D.Conservative.

New research shows that overweight or even mildly obese people have a lower risk of early death than people considered to be normal weight.

Researchers examined the results of 97 studies. Most of the studies were less than 10 years old. They included almost three million adults from around the world, including the United States, Canada, China, Taiwan, Brazil, India and Mexico.

The researchers at the National Center for Health Statistics found that people who are considered overweight or slightly obese were five to six percent less likely to die from all causes than people of normal weight. People with higher obesity ratings, however, had almost a 30 percent greater risk of death compared to normal-weight individuals.

Katherine Flegal was the lead author of the study. She says she was not surprised that overweight people would not have a higher risk of death.

“Because we’d actually already read a lot of this literature and realized it was likely that mortality rates (死亡率) for overweight would be at least not higher than normal weight. I guess I was a little bit surprised that it was definitely lower. And I was also surprised that the lower rates of obesity also didn’t seem to differ from normal weight.”

But she says the difference in death rates appears to be small between normal-weight people and those who are overweight or mildly obese.

The study has raised new questions about “body mass index,”（体重指数） or BMI. This is a measurement of body fat as a ratio（比率） of height to weight. In recent years, many public health experts have promoted body mass index as a way to predict the risk of health problems. Bu t a person's BMI can be misleading in some cases.

Steven Heymsfield ,the executive director of the Pennington Biomedical Research Center, says people can be physically fit and in good health, but might weigh more because they are more muscular.

Still, Dr. Heymsfield says people should not think gaining extra weight is OK just because of the new findings. He says being at a healthy weight lowers the risk for heart disease and diabetes（糖尿病）.

1.According to the new findings, the researchers found that __________ .

A.People with high obesity have a lower risk of early death than people with low obesity

B.People with overweight have a greater risk of early death than people of normal weight.

C.People with mild obesity are less likely to die than people of normal weight.

D.People with obesity live much longer than people of normal weight.

2.What does the underlined word “literature” in paragraph 6 mean ?

A.works like novels and poems

B.books and articles on a particular subject

C.printed material

D.magazines and newspapers

3.Which of the following statements is not true according to the passage?

A. BMI is commonly used to measure body fat as a ratio of height to weight.

B. Not all people with a little higher BMI are fat .

C. Many public health experts encourage more people to use BMI as a way to predict the risk of health problem

D. Because of the ne w findings, people should think about gaining extra weight.
