C
  A scientist who developed a way to calculate(计算) how much water is used in the produciton of anything form a cup of coffee to a hamburger was awarded the 2008 Stockholm Water Prize.
  Professor John Anthony Allan of the University of London in Britain won the award for introducing the idea of "virtual water(虚拟水)",a calculation method that has changed the nature of trade policy and research.
  Allan has written seven books and published more than 100 papers.
  The Stockholm International Water Institute said this idea is now embedded(埋藏) in the production of foods and industrial products.The institute said Allan's work had made a big effect on global trade policy and research,especially in water - scarce(缺水) regions.
  "The improved understanding of trade and water management issues on local,regional and global scales are of the highest value for the successsful and sustainable(可持续的) use of water resources,"it said.
  "People do not only use water when they drink it or take a shower,"the institute said. "Behind the morning cup of coffee,there are 140 liters of water that was used to grow,produce,package and ship the beans."That is about as much water as a person in England uses on average for all daily drinking and household needs.
  "For a single hamburger,about 2,400 liters of water are needed.In te USA ,the average person uses nearly 7,000 liters of virtual water every day" It said that was more than three times the average use of a Chinese person.

Most forest fires are caused by human carelessness, negligence, or ignorance. Forest fire prevention, therefore, is mainly a problem of creating a better understanding of the importance of forests, an awareness of the danger of fire in the woods, and a sense of personal responsibility to safeguard the forests from danger. This is not an easy job. A city dweller, used to paved street, does not easily change his smoking habits when he goes into the woods.

Careless smokers are responsible for thousands of forest fires each year. Many of these are started when cigarette butts and matches are tossed from automobiles. Others are caused by hunters, hikers, fishermen, or woods workers who are careless in disposing of their smoking material. The Forest Service has posted rules in many of the National Forests that prohibit smoking except in certain designated areas. Many of the states have laws against throwing lighted materials from automobiles. The prevention of smoker-caused fires, however, depends upon changing the attitudes and behavior of millions of people who smoke in hazardous area.

The most important natural cause of fire is lightning. This accounts for 11 percent of forest fires on protected land for the entire nation. In the western states, lightning causes a much higher percentage of fire than it does in the east.

Advances in knowledge of fire weather are helping forest protection forces to know when to be alert for lightning-caused fires. Adequate and well-equipped forces can control them quickly and hold the damage to a minimum. Experiments in “seeding” thunder clouds to prevent or control the lightning itself have been in process for many years, but new breakthroughs are needed for any significant reduction in the lightning starts.

     A. smoking in forests

     B. the chief cause of forest fire and their prevention

   3. Lightning-caused fires can be controlled quickly by——.

     A. hunters and woods workers         B. responsible smokers

     C. adequate and well-equipped forces     D changing people's habits

   4. Which of the following statements is not true?

     A. The chief causes of forest fires are human carelessness, negligence, or ignorance.

     B. Lightning, the important natural cause of forest fire, can be prevented or controlled by men.

     C.  Quite a few states in America have laws against throwing lighted materials from automobiles.

     D. “Seeding” thunder clouds are a good way to prevent forest fire.

Sports can help you keep fit and get in touch with nature. However, whether you are on the mountains, in the waves, or on the grassland, you should be aware that your sport of choice might have great influence on the environment.  

Some sports are resource-hungry. Golf, as you may know, eats up not only large areas of countryside, but also tons of water. Besides, all sorts of chemicals and huge amounts of energy are used to keep its courses (球场) in good condition. This causes major environmental effects. For example, in the dry regions of Portugal and Spain, golf is often held responsible for serious water shortage in some local areas.  

There are many environment-friendly sports. Power walking is one of them that you could take up today. You don’t need any special equipment except a good pair of shoes; and you don’t have to worry about resources and your purse. Simple and free, power walking can also keep you fit. If you walk regularly, it will be good for your heart and bones. Experts say that 20 minutes of power walking daily can make you feel less anxious, sleep well and have better weight control.  

Whatever sport you take up, you can make it greener by using environment-friendly equipment and buying products made from recycled materials. But the final goal should be “green gyms”. They are better replacements for traditional health clubs and modern sports centers. Members of green gyms play sports outdoors, in the countryside or other open spaces. There is no special requirement for you to start your membership. And best of all, it’s free.  

  64. Which of the following is the author most probably in favor of?

  A. Cycling around a lake.

  B. Motor racing in the desert.

  C. Playing basketball in a gym.

  D. Swimming in a sports center.

  65. What do we know about golf from the passage?

  A. It is popular in Portugal and Spain.

  B. It causes water shortages around the world.

  C. It pollutes the earth with chemicals and wastes.

  D. It needs water and electricity to keep its courses green.

  66. The author uses power walking as an example mainly because______.

  A. it is an outdoor sport

  B. it improves our health

  C. it uses fewer resources

  D. it is recommended by experts

  67. The author writes the passage to_______.

  A. show us the function of major sports

  B. encourage us to go in for green sports

  C. discuss the major influence of popular sports

  D. introduce different types of environment-friendly sports

When you visit America, you will see the word Motel on signs and notice boards. It is made up of “motor” and “hotel” and it is really a hotel for people who arrive by car (how-ever, you don’t need a car to stay at one). You have to pay when you arrive for your room, which usually has a bath. Meals are not provided, but there will certainly be a cafeteria (自助餐馆). Americans eat a lot of salads and sandwiches. Along the main roads there are a lot of motels. Each tries to offer more than next. Some provide television in every bedroom; others have swimming pools; and so on. Motels are especially useful when you are in the country, far from a town or city. You will also find them in the big National Parks.

In these great National Parks, you may meet guests you don’t expect to see. An American friend told me a little story. In the middle of a moonless night she heard strange noises outside her motel window in the Yellowstone National Park in Wyoming. Thinking it might be a thief, she jumped out of bed, opened the door and crept towards a dark shadow. As she got close, she saw the thief. She was dreadfully frightened: it wasn’t a human thief — it was a big black bear. The bear was turning over some empty tins with its paw, looking for tasty bits of food. My friend decided to leave that particular thief alone!

There are also, of course, places called “rooming houses”,  where they receive lodgers (房客). You will see such signs as Tourists or Rooms Rent, and you could try one of these. A word of warning — looking for a room in New York during the tourist season is like looking for gold on the moon! 

1.Which of the following is TRUE about motels?

A.You can only find motels in the big National Parks.

B.They are free for people who arrive by car.

C.If you want to stay at a motel, you must have a car.

2.Which of the following is NOT provided by motels?

D.ran fast

4.The second paragraph mainly tells us ______.

A.an interesting story

B.the experience of the author’s friend

C.we may meet animals in the National Parks

D.bears usually look for food at night

5.From the last paragraph, we can learn that in New York during the tourist season ______.
