　　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?

　　With the invention of the Internet several decades ago, do you feel that since then it has made us human beings feel more connected to the world and one another, or has it isolated(使孤立)us and made us feel more alone than ever before?

　　●　　2　　 The Internet enables us to know what’s happening in the world．We couldn't imagine talking to people everywhere in the world twenty years ago．

　　●　　3　　 It unites us because we talk to others from all around our country and the world, but the Internet can be addicting, and keep us away from people for a while, There is an inherent(内在的)human need for direct human contact(e．g．touching, talking face to face, etc．)that the Internet has all taken away．

　　●　　4　　 It has given me freedom beyond my imagination．I’m home-bound with many duties to attend to．My life is a bit too crowded．Duties duties duties．I get lost many times not knowing who I really am！This medium is my best friend．It just lets me BE！I can speak here without fear or favor．

　　●　　5　　 Chatting online is completely different from hanging out with friends outside or hearing their voice over the phone．I find that it’s not just the Internet that has increased this sense of isolation, even iPods, MP3s, such devices can separate us, make us lose focus on the everyday happenings of life．

A．I think that the Internet isolates as well as unites us．

B．I believe it unites us more than it isolates us．
