1. In fact, the idea of walking at least 10,000 steps a day for health goes back decades to a marketing (推销) campaign (计步器) launched in Japan to promote a pedometer. And, in subsequent years, it was adopted in the US as a goal to promote good health.2.
“The original basis of the number was not scientifically determined,” says researcher I-Min Lee of Brigham and Women’s Hospital.
She was curious to know how many steps you need to take a day to maintain good health and live a long life, so she and her colleagues designed a study that included about 17,000 older women. Their average age was 72.3.
It turns out that women who took about 4,000 steps per day got a boost in longevity(长寿), compared with women who took fewer steps.4.
In fact, women who took 4,400 steps per day, on average, were about 40 percent less likely to die during the follow-up period of about four years compared with women who took 2,700 steps. The findings were published Wednesday in JAMA Internal Medicine.
Another surprise: The benefits of walking maxed out at about 7,500 steps.5.
A.The women all agreed to clip on wearable devices to track their steps as they went about their day-to-day activities.
B.Walking 10,000 steps a day can make a lot of people happy.
C.It’s nothing unusual to walk 10,000 steps a day.
D.“It was sort of surprising,” Lee says.
E.In other words, women who walked more than 7,500 steps per day saw no additional boost in longevity.
F.There is no direct relationship between life span and steps.
G.It’s often the default setting on fitness trackers, but what’s it really based on?

These days, I walk down the steps leading toward the south end of the All England Club in Wimbledon, and still look for the Crow’s Nest, a small green observation tower with an outer ladder that I used to climb on for a wide view of the grounds, but which has since been knocked down.
The Crow’s Nest was a particularly useful point, because it allowed a tennis writer to keep track
of the action on as many as 10 outside courts at a time. At days end, reporters from different nations would share notes on what they had observed all over the grounds.
Twenty-seven years later, the press room has touch screens that allow us to watch live videos from any court, and even go back to watch key moments in key matches long after they have finished. You could cover Wimbledon without leaving your seat. But that is a bit like spending all your time ordering room service and looking up fun facts on Wikipedia.
More than at any other tennis tournament, there is also an appetite for stories that deal with the setting, the history and the traditions.
If they change the price of the fish tacos (鱼肉卷饼) at the United States Open, it’s not a story. If they change the price of the strawberries and cream, the signature treat at Wimbledon. It’s time to email your editor using capital letters.
The new retractable (可伸缩的) roof was put in place in 2009. Until then, you always had to have a rainy-day story in your notebook because there were no guarantees any matches would be played. Now tennis is a sure thing on Centre Court, which has made tennis reporters a bit less creative. But at least it guarantees us daily access to the most atmospheric place in the sport.
So much has changed, but Centre Court remains true to its original spirit: more a theater than a stadium. Catching that feeling is part of covering Wimbledon, too.
1.What did the author do on the Crow’s Nest in the past?
A. He made friends with reporters.
B. He reported on tennis matches.
C. He appreciated the beautiful scenery.
D. He exchanged experiences with tennis players.
2.What does the author think of the new way of covering Wimbledon?
A. It lacks fun. B. It is expensive
C. It is not convenient. D. It is not quick enough
3.Why does the author mention strawberries and cream?
A. To compare popular foods.
B. To introduce the typical treat at Wimbledon.
C. To describe people’s craze for traditional dishes.
D. To show the traditions of Wimbledon are an attraction.
4.What difference does the new roof make?
A. Audiences have easier access to a tennis court.
B. There’s less fun in watching Wimbledon indoors.
C. Reporters are struggling to find original material.
D. rainy-day stories about Wimbledon have become history.

The United States has about 475,000 school buses — all painted yellow. Each day they carry more than 25,000,000 children, half of all schoolchildren in the country. But these buses, on average, use four liters of diesel ( 柴油) fuel to travel less than sixteen kilometers. When the school year began last fall, diesel averaged 55 cents a liter nationally. The price nearly doubled, to a dollar and 8 cents, by the end of school in June.
Bob Riley speaks for the American School Bus Council. He says fuel prices for schools are not much lower than others have to pay. As a result, schools are looking for ways to reduce transportation costs. Bus routes are being redrawn or, in some cases, canceled. Some areas are buying buses that use natural gas or other alternative fuels. Other steps include fewer field trips and less travel by sports teams. And some school districts may end any bus service not required by law.
Studies show that school buses are the safest form of transportation to and from school. The American School Bus Council says cuts in bus service are bad for children and possibly the environment. It says removing buses from the road will mean an increase in other vehicles transporting students. Spokesman Bob Riley says another concern is that reducing bus services might reduce attendance.
But it could also get more children to walk or bicycle to school. And that would surely make people happy at the National Center for Safe Routes to School. More kids walking or biking safely to school is the aim of a three-year-old federal program, part of an international movement. The goal is to increase physical activity and reduce air pollution. The United States will celebrate Walk to School Day on October eighth this year. But for some students, high fuel prices could make every day a walk-to-school day.
1.What does this passage mainly tell us?
A.High fuel prices’ influences on school buses.
B.New measures to transport school students.
C.The safest form of student transportation.
D.The origin of Walk to School Day.
2.In order to cut down transportation cost, many schools take the following measures EXCEPT ______ .
A.changing some bus routes
B.stopping some bus routes
C.asking parents to drive children to and from school
D.using other types of fuels
3.The National Center for Safe Routes to School encourages more children to walk or bike to school in order to ______.
A.save more fuels and diesel for the country
B.keep the children safe on their way to school
C.make the children live a simple life
D.keep the children healthy and the environment clean

There are around 6,000 living languages in the world—and at least half of these are in danger. In every part of the world, languages are disappearing. In fact, one scientist has said that languages are in more danger of extinction than birds or animals. Professor Steve Sutherland of the University of East Anglia says that in the past 500 years 4.5 percent of languages have died out—compared with 1.3 percent of birds, and 1.9 percent of mammals.
Languages come and go, and thousands have done exactly that without leaving any trace(痕迹). Only a very few—Basque, Greek and Latin among them—have lasted more than 2000 years. But it seems that the pace of their disappearance is becoming quicker.
The Ethnologue, a database of all the languages spoken in the world, states that 417 languages are spoken by so few people that they are in the final stages of becoming extinct. If very few people speak a language, it will probably die out.
Languages may be lost through migration, as people move from small towns to city centers, or when environments are destroyed by the search for oil or wood. Natural disasters can also devastate populations, and along with them, their language. Governments also play a role in the extinction of languages. The need to establish “official languages”, for a country to educate its children and carry out its business, had a disastrous effect on many small languages.
What is lost if a language is lost? Some people argue that languages die as the human race develops. Obviously there could be great benefits if everyone in the world spoke the same language—some industries already reflect this, with English essential for pilots and air traffic controllers. But there are more important things than convenience. As languages are lost, whole ways of life and knowledge may be lost along with them.
To put it simply, language expresses something about who we are, about where we live in the world. Ani Rauhihi, a Maori teacher in New Zealand’s North Island, sums it up: “If you grow up speaking our language, you won’t know who you are.”
1.What do the figures mentioned in the first paragraph suggest?
A. Most languages have died out completely.
B. Languages are in great danger of extinction.
C. Languages are disappearing slower than before.
D. Animals are disappearing faster than languages.
2.What can best replace the underlined word “devastate” ?
A. raise
B. control
C. improve
D. destroy
3.What if a language is lost according to the passage?
A. There will be great trouble.
B. There is no need to worry about it.
C. Its culture and knowledge will also be lost.
D. People will be able to communicate with others conveniently.
4.What can we infer from the last paragraph?
A. Languages reflect our identity.
B. People will speak the same language one day.
C. Ani Rauhihi cares less about languages dying out.
D. Fewer people will remember their own languages.

The idea of being able to walk on water has long interested humans greatly. Sadly, biological facts prevent us ever accomplishing such a thing without artificial aid---we simply weigh too much, and all our mass pushes down through our relatively small feet, resulting in a lot of pressure that makes us sink.
However, several types of animals can walk on water. One of the most interesting is the common basilisk Basilicus basilicus, a lizard (蜥蜴)native to Central and South America. It can run across water for a distance of several meters, avoiding getting wet by rapidly hitting the water’s surface with its feet. The lizard will take as many as 20 steps per second to keep moving forward. For humans to do this, we，d need huge feet that we could bring up to our ears in order to create adequate w hitting. ’’
But fortunately there is an alternative : cornflour. By adding enough of this common thickening agent to water (and it does take a lot), you can create a “non-Newtonian” liquid that doesn’t behave like normal water. Now, if the surface of the water is hit hard enough, particles(粒子）in the water group together for a moment to make the surface hard. Move quickly enough and put enough force into each step, and you really can walk across the surface of an adequately thick Liquid of cornflour.
Fun though all this may sound, it’s still rather messy and better read about in theory than carried out in practice. If you must do it, then keep the water wings handy in case you start to sink--and take a shower afterward!
1.Walking on water hasn’t become a reality mainly because humans______.
A. are not interested in it
B. have biological limitations
C. have not invented proper tools
D. are afraid to make an attempt
2.What do we know about Basilicus basilicus from the passage?
A. It is light enough to walk on water.
B. Its huge feet enable it to stay above water.
C. It can run across water at a certain speed.
D. Its unique skin keeps it from getting wet in water.
3.What is the function of the cornflour according to the passage?
A. To create a thick liquid.
B. To turn the water into solid.
C. To help the liquid behave normally.
D. To enable the water to move rapidly.
4.What is the author’s attitude toward the idea of humans’ walking on water?
A. It is risky but beneficial.
B. It is interesting and worth trying.
C. It is crazy and cannot become a reality.
D. It is impractical though theoretically possible.

People aren't walking any more—if they can figure out a way to avoid it.
I felt superior about this matter until the other day I took my car to mail a small parcel. The journey is a matter of 281 steps. But I used the car. And I wasn't in any hurry, either. I had merely become one more victim of a national sickness: motorosis.
It is an illness to which I had thought myself immune(免疫的), for I was born in the tradition of going to places on my own two legs. At that time, we regarded 25 miles as good day's walk and the ability to cover such a distance in ten hours as a sign of strength and skill. A wellknown British physician, Sir Adolphe Abrhams, pointed out recently that hearts and bodies need proper exercise. A person who avoids exercise is more likely to have illnesses than one who exercises regularly and walking is an ideal form of exercise---the most familiar and natural of all.
It was Henry Thoreau who showed mankind the richness of going on foot. The man walking can learn the trees, flowers, insects, birds and animals, the significance of seasons, the very feel of himself as a living creature in a living world. He can’t learn in a car.
The car is a convenient means of transport, but we have made it our way of life. Many people don't dare to approach Nature any more. To them the world they were born to enjoy is all threat; to them security is a steel river thundering on a concrete road. And much of their thinking takes place while waiting for the traffic light to turn green.
I say that the green of forests is the mind's best light. And none but the man on foot can evaluate what is basic and everlasting.
1.What is the national sickness?
A.Walking too much.
B.Travelling too much.
C.Driving cars too much.
D.Climbing stairs too much.
2.What was life like when the author was young?
A.People usually went around on foot.
B.People often walked 25 miles a day.
C.People used to walk ten hours every day.
D.People considered a tenhour walk as a hardship.
3.What is compared to “a steel river” in Paragraph 6?
A.A queue of cars.
B.A ray of traffic light.
C.A flash of lightning.
D.A stream of people.
4.What is the author's intention of writing this passage?
A.To tell people to reflect more on life.
B.To encourage people to return to walking.
C.To advise people to do outdoor activities.
D.To recommend people to give up driving.

There are at least 3 ,000 miles of waterways in Britain. On these canals and rivers, there are over 30,000 'houseboats'—boats that people use as homes. Around 10 ,000 of them are located in London.
The earliest populations of Britain's 'boat people' have been living on the water since the canals were built during the industrial revolution. Since then, houseboat living has usually attracted people who prefer to live an alternative lifestyle. Houseboat communities are typically made up of people who are looking for a slower way of life and who want to be in touch with nature.
Living on the water sounds romantic, but it is also hard work. There are daily things that need to be done, like bringing fuel and water on board and dealing with 'waste' water from kitchen sink, shower and toilet. In winter, living on a boat can be very cold and there is always a feeling of damp. Of course, most boats are quite small inside, so you don't have much space, especially if you are a couple, family or a group of friends.
Despite these difficulties, the number of people living on Britain's waterways has increased by around 50 per cent over the past ten years. More and more families and young professionals are moving onto houseboats, not only because they like the idea of life on water.but also because it is much cheaper to buy or rent a boat than a flat or a house.
There is a great sense of community on the waterways ； many boat people say that their neighbours are always ready to help them, and houseboat neighbours often become friends for life. This is quite a different story from people who live in flats or houses and may hardly know the people next door at all.
1.What does the underlined word "alternative" in paragraph 2 probably mean?
A.Creative. B.Enjoyable.
C.Non — traditional. D.Primitive.
2.From the third paragraph, we know that it is to live on the boat.
A.inconvenient B.easy
C.boring D.unforgettable
3.Which of the following information is not given in the text?
A.There are lots of rivers and canals in Britain.
B.Many people live on houseboats in Wales.
C.Houseboat living become popular in the industrial revolution.
D.People who live on houseboats are usually very friendly with their neighbours.
4.Why do many people choose to live on the water? Because .
A.living on the water is romantic
B.living on the water is easy and natural
C.living on the water can avoid unfriendly neighbours
D.living on the water costs less than living on the land
