Researchers say current exercise guidelines are unrealistic and argue that doctors should sometimes advise small increases in activity instead. They warn the 150-minute weekly target is beyond the reach of some people — particularly older individuals. And striving to reach these goals could mean the benefits of lighter exercise are overlooked. But public health officials say current recommendations have proven benefits in lowering the risk of heart disease.
There is increasing evidence that inactivity is linked to heart disease, Type 2 diabetes(糖尿病) and some types of cancer. UK guidelines for adults recommend at least two-and-a-half hours of moderate activity a week, in short periods of 10 minutes or more.
But in two separate articles in the BMJ, experts argue the message needs to change, with greater emphasis on making inactive people move more. Prof Philipe de Souto Barreto at the University Hospital of Toulouse, advises people who are sedentary(久坐的) to make small incremental increases in their activity levels — rather than pushing to achieve current goals. He points to previous studies which show even short periods of walking or just 20 minutes of vigorous activity a few times a month can reduce the risk of death, compared to people who do no exercise.
In the second article, Prof Phillip Sparking of the Georgia Institute of Technology, says doctors should tailor their advice — particularly for older patients. He suggests using GP visits for people over 60 to discuss "realistic options" to increase activity — such as getting people to stand up and move during TV commercial breaks.
Prof Kevin Fenton at Public Health England, says: "Everyone needs to be active every day — short periods of 10 or more minutes of physical activity have proven health benefits, but getting 150 minutes or more of moderate activity every week is the amount we need to positively impact on a wide range of health conditions. "This includes reducing the risk of heart disease and type 2 diabetes."
1.What is the current exercise goal mentioned in the passage?
A. 10-minute exercise. B. 20-minute exercise.
C. 60-minute exercise. D. 150-minute exercise.

A. A 10-minute exercise has little effect on the health.
B. Heart diseases happen easily to the old in activity.
C. Two-and-a-half hours of exercise is not necessary.
D. Inactivity easily brings about many serious diseases.
3.What is the suggestion of Prof. Philipe de Souto Barreto according to the third paragraph?
A. People should spend less time on exercise.
B. People should lower their activity levels.
C. People should increase exercise properly.

Shyness is the cause of much unhappiness for a great many people. Shy people are anxious and self-conscious; that is, they are concerned with their own appearance and actions too much. Negative thoughts are constantly occurring in their minds: What kind of impression am I making? Do they like me? Do I sound stupid? Am I wearing unattractive clothes?
It is obvious that such uncomfortable feelings must affect people unfavorably. A person's self-concept is reflected in the way he or she behaves and the way a person behaves affects other people's reactions. In general, the way people think about themselves has a deep effect on all areas of their lives.
Shy people, who have low respect, are likely to be passive and easily influenced by others. They need faith that they are doing "the right thing". Shy people are very sensitive to criticism. It makes them feel inferior(自卑). They also find it difficult to be pleased by praises because they believe they are unworthy of praise. A shy person may respond to a praise with a statement like this one: "You're just saying that to make me feel good, I know it's not true.” It is clear that, while self-awareness is a healthy quality, overdoing it is harmful.
Can shyness be completely got rid of, or at least reduced? Fortunately, people can overcome shyness with determination since shyness goes hand in hand with lack of self-respect. It is important for people to accept their weakness as well as their strengths. Each one of us has his or her own characteristics. We are interested in our own personal ways. The better we understand ourselves, the easier it becomes to live up to our chances for a rich and successful life.
1.The first paragraph is mainly about ________.
A. the effect of shyness on people B. the cause of shyness
C. the feelings of shy people D. the questions in the minds of shy people
2.According to the writer, self-awareness is ________.
A. harmful to people B. a healthy quality
C. the cause of unhappiness D. a weak point of shy people
3.The underlined word “it” in Paragraph 3 refers to ________.
A. shyness B. criticism C. sensibility D. praise
4.We can learn from the passage that shyness can ________.
A. have nothing to do with lack of self-respect
B. help us to live up to our full development
C. enable us to understand ourselves better
D. be overcome with determination

Raised in a motherless home, my father was extremely tightfisted towards us children. His attitude didn’t soften as I grew into adulthood and went to college. I had to ride the bus whenever I came home. Though the bus stopped about two miles from home, Dad never met me, even in severe weather. If I grumbled, he’d say in his loudest father-voice, “That’s what you are for!”
The walk didn’t bother me as much as the fear of walking alone alone the highway and country roads. I also felt less than valued that my father didn’t seem concerned about my safety. But that feeling was cancelled one spring evening.
It had been a particularly difficult week at college after long hours in labs. I longed for home. When the bus reached the stop, I stepped off and dragged my suitcase to begin the long journey home.
A row of hedge（树篱）edged the driveway that climbed the hill to our house. Once I had turned off the highway to start the last lap of my journey, I always had a sense of relief to see the hedge because it meant that I was almost home. On that particular evening, the hedge had just come into view when. I realized it was the top of my father’s head. Then I know, each time I’d come home, he had stood behind the hedge , watching, until he knew I had arrived safely. I swallowed hard against the tears. He did care, after all.
On later visits, that spot of gray became my watchtower. I could hardly wait until I was close enough to watch for its secret movement above the greenery. Upon reaching home, I would find my father sitting innocently in his chair.“So! My son, it’s you!” he’d say, his face lengthening into pretended surprise.
I replied, “Yes, Dad ,it’s me. I’m home.”

Why do Americans struggle with watching their weight, while the French, who consume（消耗） rich food, continue to stay thin? Now a research by Cornell University suggests how life style and decisions about eating may affect weight. Researchers concluded that the French tend to（往往，倾向于） stop eating when they feel full. However, Americans tend to stop when their plate is empty or their favorite TV show is over.
According to Dr. Joseph Mercola, a health expert, the French see eating as an important part of their life style. They enjoy food and therefore spend a fairly long time at the table, while Americans see eating as something to be squeezed（挤出） between the other daily activities. Mercola believes Americans lose the ability to sense when they are actually full. So they keep eating long after the French would have stopped. In addition, he points out that Americans drive to huge supermarkets to buy canned and frozen foods for the week. The French, instead, tend to shop daily, walking to small shops and farmers’ markets where they have a choice of fresh fruits, vegetables, and eggs as well as high-quality meats for each meal.
After a visit to the United States, Mireille Guiliano, author of French Women Don’t Get Fat, decided to write about the importance of knowing when to stop rather than suggesting how to avoid food. Today she continues to stay slim and rarely goes to the gym.
In spite of（尽管） all these differences, evidence shows that recent life style changes may be affecting French eating habits. Today the rate of obesity — or extreme overweight — among adults is only 6%. However, as American fast food gains acceptance and the young reject（拒绝） older traditions, the obesity rate among French children has reached 17% — and is growing.
1.In what way are the French different from Americans according to Dr. Joseph Mercola?
A. They go shopping at supermarkets more frequently.
B. They squeeze eating between the other daily activities.
C. They regard eating as a key part of their lifestyles.
D. They usually eat too much canned and frozen food.
2.This text is mainly the relationship between _________.
A. Americans and the French
B. life styl
e and obesity
C. children and adults
D. fast food and overweight
3.The text is mainly developed __________.
A. by contrast （对比） B. by space C. by process（变化过程） D. by classification（分类）
4.Where does this text probably come from?
A. A TV interview B. A food advertisement
C. A health report D. A book review（书评）

What a Scientist Is Like
If you were asked to imagine a scientist,what image（形象）would come to your mind?The common idea that most kids from kindergarten through college have of a scientist is a man wearing a white lab coat with messy hair, big glasses,and several glass cups of mysterious colorful liquids giving off clouds of smoke.As for adults,the majority view scientists as strange people who spend 100 hours a week slaving away in a lonely laboratory.However, the reality is quite different.
Recently I’ve had a chance to take part in a scientific experience far from my laboratory and into Costa Rica.It supports a huge amount of wildlife due to its geographical placement between North and South America.It is home to more than 500,000 species,which represents nearly 4% of the total species worldwide!
First we worked alongside conservationists to preserve wildlife at a leatherback turtle（棱皮龟）rescue center. We helped the volunteers preserve turtle populations by removing rubbish from the shoreline to create a safe environment for turtle eggs to come out.After that we stayed at Mount Arenal where we studied seismic activity relating to earthquakes.During our stay at Arenal,we rode over the mountainous areas and took a long walk through the rainforest.After reaching the top,we went down and through waterfalls to the beautiful valley below!On the last day we got a hands-on introduction to rocket science where we learned about new rocket technology that will be used on the international space station.
During my Costa Rica experience,I know that being a scientist doesn’t mean working in a lab all day and night. A scientist is one who loves learning and getting a better understanding of the world from helping preserve wild-life, learning about earthquakes or inventing rockets.I think that schools should really stress that science is so much more than wearing a lab coat and mixing chemicals.Kids need to be aware of the excitement and adventures science can bring!
1.According to the first paragraph,scientists are often believed .
A. to work as slaves B. to behave in a strange way
C. to spend too much time in labs D. to do experiments in messy labs
2.The author helped to preserve the turtle population by .
A. creating a safe nest for turtles B. picking up rubbish on the shoreline
C. collecting the turtle eggs on the beach D. finding a comfortable environment for turtles
3.What does the author learn about science from his experience?
A. Science is full of boring experiments. B. Science is more than working in a lab.
C. Science is related to mysterious liquids. D. Science is about wildlife and earthquakes.
4.Why does the author write this passage?
A. To encourage kids to study science. B. To tell the story of traveling in Costa Rica.
C. To expect more people to travel in Costa Rica. D. To share the secrets behind science phenomena.
