Drinking a lot of water does not do any good to the body, according to two experts in the United States. In fact, they warn, drinking too much water could be, in certain cases, harmful.
In a study, Dr Stanly Goldfarb and Dr Dan Negoianu, both of the Renal, Electrolyte and Hypertension Division at the University of Pensylvania, the United States, have denied the popular belief that drinking a lot of water clears body toxins(毒素)better, improves skin, and helps reduce weight.
Dr Goldfarb and Dr Negoianu say that they found little proof to back the public opinion that drinking 8 glasses of water every day benefits health. At the same time, they fond little proof of harm in drinking 8 glasses of water every day.
It is widely believed that in some cases-such as athletes, people who live in hot, dry environments, and those with certain medical conditions-drinking a lot of water indeed helps, but no studies have been done to prove the benefits of this practice in average, healthy people, the website medheadlines.com reports.
The study at the University of Pennsylvania also examined reports that some people experienced increased headaches when their consumption(消耗)of water was low. In one small study, which the doctors reviewed, the group drinking the most water reported fewer headaches than the control group, “but the difference in the number of headaches was o small between the two groups as to be considered unimportant.”
The researchers concluded that there is no scientific proof to support that average, healthy people need to drink at least 8 glasses of water each each day.
The website medheadines.com says that, according to an Indian doctor, drinking too much water is harmful. If water enters the body more quickly than it can be removed, problems can occur

More and more people are choosing to take their holidays in the UK rather than travel abroad.
In the late 1970s, air travel became affordable for the average family in the UK, and more and more British people started traveling abroad for their summer holidays. After all, the British weather wasn't very good, even in summer, so a lot of British people left the UK for a vacation. Particularly popular with families on a budget was the "package holiday", where the cost of flights and hotels were offered as one discounted price by travel agents.
In the 1980s and 1990s, young people in the UK became wealthier on average, or at least had more money left after they spent on the living cost. As a result, they started to go abroad in groups, to places such as Spain and Greece.
British holidaying habits have begun to change, however. Climate change means that the UK now has a hotter climate than before, so people do not need to go abroad to find good weather. Also, the credit problem has affected the international value of the British pound, so going abroad is more expensive than it used to be. As a result, more and more British people are choosing to spend their summer holidays in the UK.
This year, British hotels in areas such as the English Lake District have seen a 40 percent increase in booking compared with last year. That rise is mainly owing to the British staying in their own country for their holidays. In addition, however, foreign tourists are now finding the UK cheaper to visit than previously.
In the UK, the national tourism industry — when people go on holiday in their own country — is healthier than it has been in decades. The UK has always been famous for its international explorers. It is only just starting to discover itself, however.?

For more than two decades, Oprah Winfrey has been the change-your-life champion who ruled over daytime television much like Johnny Caron once ruled late night.
However, now she’s ready to say goodbye, Wimfrey told viewers Friday that The Oprah Winfrey Show would close in September 2011 after 25 years on the air.
“I love this show. This show has been my life. And I love it enough to know when it’s time to say goodbye,” Winfrey said, holding back tears.
Winfrey’s show “is one of daytime television’s very foundations,” said Larry Gerbrandt an analyst for the firm Media Valuation Partners in Los Angeles. “Stations build their schedules around her. They gave it the best time period and used it to promote other shows.”
Winfrey offered no specific plans for the future, except to say that she intended to produce the best possible shows during the final two years.
“I just wanted to say whether you’ve been here with me from the beginning or you joined me last week, I want you all to know that my relationship with you is one that I hold very dear,” she said. “Your trust in me and the sharing of your precious time every day with me have brought me the greatest joy I have ever known.”
The Oprah Winfrey Show’s open atmosphere and frank conversation determined the talk show style and made Winfrey one of the most influential women in the US as well as the wealthiest black woman in the world.
“She has had great effects on today’s society. She’s just part of every one’s life,” said Yasmeen Elhaj, a 19-year-old student from Chicago.

Bored by the Chinese courses he was majoring in, Zuo Cheng, 18, couldn't imagine having to drag himself into class day after day, week after week, for four years. The Beijing Language and Culture University student decided that enough was enough. After rounds of examinations and interviews, he managed to transfer (转移) to the Department of International Accounting.
"It may seem like I've wasted a year and have to start college all over again, but now that I've settled on a field, I'll be able to concentrate." Zuo said. Zuo is not alone.
At the China Three Gorges University in Yichang in Hubei province 53 out of 59 students in the Physics Department took transfer exams last term. Unfortunately only 22 of them got a place on another major.
Jiang Xin, 20, who was able to switch to electrical engineering and automation from physics, said that physics graduates had few other choices besides going into teaching. He added that a career in education just didn't suit him.
"I should have better job prospects (前景) and the chance to earn more money once I graduate," Jiang said. Many first year college students find their majors uninteresting.
However, Shao Yanfang, who works at the admissions office of a university, advised students to consider both short-term and long-term goals. "After graduation do you want to find yourself in a job very specifically related to your college major? Or, would you like to possess the knowledge and skills that will enable you to work in many areas? These are the questions students need to consider. Above all, your choice of major should be based on your own interests, abilities and personality," Shao said.

People in the United States honor their parents with 2 special days: Mother’s Day on the second Sunday in May and Father’s Day on the 3rd Sunday in June. These days are to show love and respect for parents. They raise their children and educate them to be responsible citizens. They give love and care. These two days offer an opportunity to think about the changing roles of mothers and fathers. More mothers now work outside the home and more fathers must help with childcare.
These two special days are celebrated in many different ways. On mother’s Day, people wear carnations. A red one symbolizes a living mother. A white one shows that the mother is dead. Many people attend religious services to honor parents. It’s also a day when people whose parents are dead visit the cemetery(grave). On these days families get together at home as well as in restaurants. They often have outdoor barbecue for Father’s Day. These are days of fun and good feelings and memories.
Another tradition is to give cards and gifts. Children make them in school. Many people make their own presents. These are more valued than those bought in stores. It’s not the value of the gift that is important, but “the thought that counts”. Greeting card stores, florists, candy makers, bakers, phone companies and other stores do lots of business during these holidays.

Blogs are being used more and more by teachers. Many Internet services now offer free and easy ways to create personal Web pages.
Through comments on blogs, or Web logs, teachers can share their classroom experiences. They can exchange ideas and discuss successes and failures. They can debate educational policies. Or they can just sympathize with each other.
A teacher in the American state of North Carolina recently wrote on her blog: “Apparently the teachers at my school use too much paper. So my principal yelled at everyone at the last staff meeting for, like, ten minutes. Now, I’ve just been told, we are not getting anymore paper for the rest of the year.”
This unidentified blogger is now in her third year of teaching, but still calls her site firstyearteacher.blogspot.com.
A blogger who calls himself Minister Lawrence works as a substitute teacher. In April he wrote about a disputed plan to split the Omaha, Nebraska, public schools into separate systems for black, Latino and white students. Supporters say minority parents do not have enough power over their children’s education.
But Minister Lawrence wrote at teachersparadise.blogspot.com: “I’m afraid that what this says’ to a lot of people is that blacks, whites and Hispanics are not equal, and “reinforces” racist beliefs among people.”
Educators did not become involved with blogging right away. Many were concerned with privacy issues and security. But now, thousands of teacher blogs can be found on the Internet. Many teachers do not identify themselves, and they change the names of students and co-workers.

Is it true that cats have nine lives? One 4-year-old American cat named Sugar definitely seems to have more than one. Sugar fell from the 19th floor of her owner’s home in Boston last month and was only hurt a little on her chest.
“This story isn’t much of a surprise,” said Jake Socha, a scientist at Virginia Tech University, US, in an interview with the BBC. “There have been lots of records of these cats surviving.”
Back in 1987, scientists studied 132 cats. All of them had been brought to a vet’s clinic in New York after falling from tall buildings. Around 90 percent of these cats were alive after their fall and only 37 percent had been seriously injured.
“Being able to survive falls is a
critical
thing for animals that live in trees, and cats are one of them,” said Socha.
Cats have developed special body structures to survive accidental falls. Their legs are muscular. This can protect their bones from breaking, Professor Andrew Biewener from Harvard University told the BBC. Cats can also spread out their legs like a parachute to reduce their falling speed, he said.
The strange part, according to scientists, is that cats have a better chance of survival if they fall from higher than seven stories. This is because cats have a good sense of which way is down. They can twist their bodies as they fall to make sure they land on their feet. A higher fall means more time for the cat to change its body position.
However, you should not throw your cat out of the window to see how this works. Most pet cats are overweight nowadays. They are not fit enough to change their position in midair, warned Steve Dale, an American cat behavior scientist.
“This cat (Sugar) was lucky,” Dale said. In fact, most cats would suffer serious lung damage, a broken leg or a broken jaw or teeth damage, he said.

One day in January, my uncle, my cousin and I decided to go hunting.We left by car in the afternoon.It was a Range Rover with four-wheel drive.It took us three hours to get there.After we arrived at 5:15 p.m., we fixed the tent, then made coffee and had a short rest.After that, we went hunting, using a falcon(猎鹰).We spent two hours without finding anything.On our way back to the camp, my cousin saw a rabbit.I removed the falcon’s bead cover and let go of the aggressive falcon.When the rabbit saw the falcon, it ran fast, but my falcon was a professional hunter.He flew up and came down to trick the rabbit.After two minutes, the rabbit was caught.We took it back to the camp to cook our dinner.We ate the delicious food, drank Arabic coffee, and sat around the fire talking until 10:30 p.m.
We left the camp the next day at 7 o’clock in the morning.We went north.However, around 10:00 a.m.our car got stuck in the sand!

When I got up, it was dark.I continued to walk south.I was worried about my uncle and cousin.Suddenly, I met a Bedouin man who was riding his camel.He took me to his house.When I had had enough rest, I asked him to take me to the road where I found a car.It took me to the city to get help.I had one day to get back to my uncle and cousin.When I got back to them, they were so happy because I had gotten help and they were able to see me again.
