摘要: 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 答案:56-59 ADCB B The surprising experiment I am about to describe proves that air is all around you and that it presses down upon you. Air pressure is a powerful force. When you swim underwater, you can feel water pushing on your body. The air all around you does the same. However, your body is so used to it that you do not notice this. The pressure is caused by a layer (层) of air called the atmosphere. This layer surrounds the Earth, extending to about five kilometers above the Earth’s surface. The following experiment is an easy one that you can do at home. But make sure that you are supervised , because you will need to use matches. Now for the experiment. What you need ● hard-boiled egg without the shell ● A bottle with a neck slightly smaller than the egg ● A piece of paper ● A match Method 1) Check that the egg will sit firmly on the neck of the bottle. 2) Tear the paper into pieces and put them into the bottle. 3) Light the paper by dropping a burning match into the bottle. 4) Quickly sit the egg on the neck of the bottle. Result Astonishingly, the egg will be sucked into the bottle. Your friends will be amazed when you show them the experiment. But be careful when you handle matches. Why it happened? As the paper burns, it needs oxygen and uses up the oxygen (air) in the bottle. The egg acts as a scale in the neck of the bottle, so no more air can get inside. This reduces the air pressure inside the bottle. The air pressure must equalize, so more air from outside must enter the bottle. The outside air presses against the egg, and then the egg is pushed into the bottle! This proves that air is all around and that it is pressing down on us.

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?

  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.

  B. it improves our health
