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. 1.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. 2. “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. 3.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: 4.
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. 5. “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?

In 1990 a report was published about what the earth might be like 20 years from then on. 71 According to the report,the picture of the earth in the year 2010 is not a pleasant one. 72 The population could be as large as 6300 million,almost 2150 million more than in 1985.More people would move into cities ,especially cities in developing countries.Cities like Cairo and Jakarta probably would each have 15 million by then.
73 Farmers will grow 90% more food than they did in 1985,but most of the increase would be in countries that already produce enough food for their people. 74 Poor farming ways are destroying large areas of crop land,changing farms into deserts.More farmland is lost as cities become larger and more houses are built.Air pollution will get worse as industrial countries burn more coal and oil.Many of the world's forests could disappear as more and more trees are cut down.Energy will continue to be a serious problem. 75 They only workde out the situation that exists today.By changing the situation,by settling the problems,the picture can be changed.There is still time for the nations of the world to work out a plan of action.But they warned that waiting too long to make de cisions would greatly reduce the chances of success.
