Is bottled water better for you than tap? Or should you choose vitamin-enriched water? Experts say, skip it all. None of these products is likely to make you any healthier. Below, we look at four major myths about the benefits of drinking water. 71 Experts say there’s an easy way to judge. If you are not thirsty, your fluid intake is likely “just right”

Myth No 1: Drink eight glasses each day.

Scientists say there’s no clear health benefit of drinking so much water a day. 72 “Nobody really knows,” says Dr. Stanley Goldfarb, a kidney expert at the University of Pennsylvania.

Myth No.2:Lots of water equals healthier skin.

The body is already 60 percent water. 73 Adding a few extra glasses of water each day has a limited effect. “It’s such a tiny part of what’s in the body,” says Goldfarb. “ It’s very unlikely that one’s getting any benefit.”

Myth No.3: 74

A more accurate statement may be: Drinking water is a helpful tool for dieters. “Water is a great strategy for dieters because it has no calories,” says Madeline Fernstrom of the University of Pittsburgh. “So you can keep your mouth busy without food and get a sense of satisfaction.” But water is not magical, she adds. “Other zero-calorie options such as diet sodas are fine, too.”

Myth No. 4: It’s easy to get dehydrated(脱水的) during a workout.

Dehydration sets in when a person has lost 2 percent of his or her body weight. 75 “It’s also obvious that individuals in hot, dry climates have an increased need for water,” says Goldfarb. “But for a walk in the park, no water bottle is necessary.”

A.        So where does the standard advice come from?

B.        But it’s unclear whether these changes are clinically significant.

C.        So for a 200-pound man, this means losing 4 pounds of water.

D.       Drinking extra water leads to weight loss.

E.        Drink as much water as you can.

F.        So, if you take a 200-pound man, he’s 120 pounds of water.

G.       But first, how do you know if you’re drinking enough water?

As the population of the planet increases, so does the number of homes, businesses, parking lots, schools, airports and roadways. All these structures use electricity and need to be lighted. Humans demand these lights. They want their homes more comfortable and they want their streets sage. The problem is that researchers are finding that all the light is having a negative effect on humans and wildlife as well.

Less than 10 years ago I drove to a thinly populated section of my town, lay down in the middle of the road and watched an attracted meteor shower(流星雨). The area was short of homes, street lights and traffic. If I did that today, I wouldn’t be able to see the meteor shower as well, and I would surely be run over by a car.

Nowadays scientists are finding light pollution can be almost as bad as carbon dioxide pollution. If you’ve ever taken a flight at night, the view is beautiful, but you must remember that all the light you see is wasted electricity. The crew of the space shuttles see an even bigger picture of how extensive the wasted electricity is worldwide.

Additionally, electricity needs to be generated, and the generation of electricity creates pollution by giving off greenhouse gases. This affects the air we breathe and our quality of life.

Scientists are also studying the effects of light pollution on wildlife. Thousands of birds die each year when they crash into highly lighted buildings, as they become puzzled by the light. It has been long known that tiny sea turtle hatchlings become lost and follow lights on the shore instead of heading towards the sea.

Fortunately, light pollution is one of the easiest sources of pollution that can be corrected without a negative effect. Following some guidelines and a little searching on Google can give you many ideas on how to reduce your contribution to light pollution.

       D. More bad effects of light pollution

Andrew Carneigie, known as the King of Steel, built the steel industry in the United States, and, in the process, became one of the wealthiest men in America. His success resulted partly from his ability to sell the product and partly from his policy of expanding during periods of economic decline, when most of his competitors were reducing their investments. Carnegie believed that individuals should progress through hard work, but he also felt strongly that the wealthy should use their fortunes for the benefit of society. He opposed charity, preferring instead to provide educational opportunities that would allow others to help themselves. “He who dies rich, dies disgraced”, he often said. Among his more noteworthy contributions to society are those that bear his name, including the Carnegie Institute of Pittsburgh, which has a library, a museum of fine arts, and a museum of national history. He also founded a school of technology that is now part of Carnegie-Mellon University. Other philanthropic(慈善的) gifts are the Carnegie Endowment for International Peace to promote understanding between nations, the Carnegie Institute of Washington to fund scientific research, and Carnegie Hall to provide a center for the arts. Few Americans have been left untouched by Andrew Carnegie’s generosity. His contributions of more than five million dollars established 2,500 libraries in small communities throughout the country and formed the nucleus of the public library system that we all enjoy today.

My wife passed away a few years ago, and I went through the worst time in my life. I even wanted to kill myself. Just for kids, I had to continue to live and work as small-town doctor at my medical clinic in Hawaii. My kids had gone to live on the mainland, and I was alone. Then they asked me to have a family trip.

On our trip, we turned on the TV at the motel and saw the second plane crash into the World Trade Center. Seeing it falling down, I said to my kids: “I’m going to Afghanistan”. And a few weeks later, international Medical Corps sent me to set up 20 clinics in provinces where people had no health care. In these field clinics surrounded by frightening shoots or deadly bombs, we were eventually serving 27,000 patients a month in a very busy schedule. Tired and nervous, I gradually had a sense of achievement, a sense of purpose, and my depression went away.

In the years to follow, I went to Indonesia after the tsunami, Pakistan after the earthquakes, Sudan after the civil warm and Iraq after more and more bombs. Each time after disasters one after another, hundreds of people were killed, wounded and many more had to flee. We once set up movable clinics in an area with 19,000 refugees, and it was supposed to hold 13,000 originally. Flu broke out, one of the biggest killers of kids in refugee camps, and it spread like wildfire. Water and food were also serious problems. “Adventures or not?” I often asked myself.

When my wife passed away, I thought my life was done. But in reality, it was just getting started. At the end of her life, she went unconscious. I held her head in my hands and told her of all the places we would visit and the exciting adventures we would have.

I think about the moment many times during my “adventures”. I didn’t know how predictive those words would be. But I know that she is still with me.

56. Where has the doctor been in the past few years?

       A. Some countries where he could set up clinics.

       B. Some African countries where flu broke out.

       C. The places where the earthquakes happened.

       D. The places that the horrible disasters struck.

57. How would the doctor describe his life after he had worked in Afghanistan?

       A. Tired and troublesome.                           B. Busy and risky.

       C. Meaningful and helpful                              D. Frightening and depressing.

58. The underlined word “refugees” means people_______________.

       A. who are robbed, killed, or wounded

       B. who suffer from flu in movable clinics

       C. who like to take adventures

       D. who have lost homes because of disasters.

59. Which of the following is TRUE according to the passage?

       A. the doctor’s wife encouraged him to work in foreign countries.

  The school was across the street from our home and I would often watch the kids as they played during the break .She seemed so small as she pushed her way 36 the crowd of boys on the playground .She 37 from them all.
  I began to notice her at other times, basketball in hand, playing 38.She would practice dribbling(运球) and shooting over and over again, sometimes until 39 . One day I asked her 40 she practiced so much. She looked 41 in my eyes and without a moment of hesitation she said, "I want to go to college. The only way I can 42 is that if I get a scholarship, I am going to play college basketball. I want to be 43 . My Daddy told me if the dream is big enough, the facts don't count."
  Well, I had to give it in to her--- she was 44 .One day in her senior year, I saw her sitting in the grass, head 45 in her arms. I walked toward her and quietly asked what was 46 . "Oh, nothing," came a soft reply. "I'm just too short." The coach told her that at her height she would probably 47 get to play for a top ranked team, 48 offered a scholarship. So she 49 stop dreaming about college.
  She was 50 and I sensed her disappointment. I asked her if she had talked to her dad about it yet. She told me that her father said those coaches were wrong. They just didn't 51 the power of a dream. He told her 52 she really wanted to play for a good college, if she truly wanted a scholarship, 53 could stop her except one thing-- her own attitude. He told her again," if the dream is big enough, the facts don't count."
  The next year, as she and her team went to the Northern California Championship game, she was seen by a college recruiter(招聘人员). She was indeed offered a 54 .She was going to get the college education that she had 55 and worked toward for all those years.
