　　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?

TUVALU, a tiny country in the Pacific Ocean, has asked for help as it will be swallowed up by the sea.
Storms and huge waves are a constant threat and none of Tuvalu’s nine little islands is more than five meters above sea level. Salt water is already entering the country’s drinking water supply, as well as damaging plants that produce fruit and vegetable. Without urgent help, the country’s days are numbered.
But Tuvalu is not the first place to face sinking into the sea. Venice, a historic city in Italy best known for its canals, has sunk about 24cm over the past 100 years. Experts say that it will have sunk another 20-50cm by 2050. A century ago, St. Mark’s Square, the lowest point city, flooded about nine times a year. Nowadays, it happens more than 100 times. While Venice is slowly sinking into the mud on which it stands, global warming causes Tuvalu’s rising sea level.
The average global temperature has increased by almost 0.5 centigrade degrees over the past century; scientists expect it rise by extra 1-3 degrees over the next 100 years.
Warmer weather makes glaciers (冰川) melt, and adds more water to the ocean. The warmer temperatures also make water expand, so it takes up more space, causing the sea level to rise. The sea level has risen about 10-25 cm in the last 100 years.
The main cause of global warming is human pollution. Through burning coal, oil and gas, people have been increasing the greenhouse gases in the atmosphere, such as CO2. This adds to the power of the greenhouse effect, making the planet even warmer.
Many scientists believe that, if the warming is not stopped, there will be huge climate changes. The sea level could rise by one meter this century.
Should this come true, the sea will swallow up millions of homes and the world will be flooded with “climate refugees” looking for somewhere to live.

A. Tuvalu is in danger of being swallowed up by the sea

Watching a sporting event with family and friends under the sun is a great experience in summer. 1. In the United States, heat exposure led to 8,000 deaths between 1979 and 2003. Luckily, a little prevention can go a long way towards making sure of an enjoyable day.

Know the danger

Heat-related illnesses do not require record-breaking temperatures to occur. 2. The body’s temperature can reach 106 or 107 degrees Fahrenheit on a 90-degree day, creating a potentially deadly situation. Factors such as age, weight or a medical condition can influence people.

Drink plenty of water

3. Sweating is your body’s key way to keep cool, so drink water to stay well hydrated(含水的) before you feel thirsty. A cool beer may sound perfect on a hot day, but drink responsibly. Alcohol stops the body’s cooling system and causes you to go to the bathroom frequently.

Wear light-colored and loosely fitting clothing, so air can go around your body and help keep you cool. A hat is a must to help you keep cool, since your head contains many blood vessels(血管), and sun block(防晒乳) is always a good idea.

Take action

What should you do if you are suffering from the heat while watching your favorite event?

Get up and go. It is a simple piece of advice, but could make the difference between a quick recovery and something more severe that requires medical attention. The ideal thing is to move yourself from the position you’re in to an area that is a little cooler. 5.

A. Dress for the occasion

B. Weather-related causes

C. In hot weather, it is essential to stay hydrated.

D. You may miss a little of the action, but it beats missing a lot.

E. But when you add sun exposure to the crowds, the results can be deadly.

F. It is also important to take advantage of services the equipment provides.

G. Temperatures between 80 and 90 degrees Fahrenheit can be dangerous.
