It has become a certain belief among the public-drink at least eight glasses of water a day to improve health and well--being.Bottled water companies often repeat it to increase their sales but it is actually a silly idea. There is no evidence to prove the advantages of drinking eight glasses of water a day,scientists say. The misunderstanding is caused from the suggestion that adults should drink 2.5 liters of water daily,which was highlighted(,)by the British Medical Journal in December.The important part of the suggestion that most of this quantity of water is contained in prepared foods,however,is usually ignored. U.S.researchers who reviewed the evidence concluded that most people do not need to worry about the amount of water they drink every day.Besides drinking water,they will be getting plenty of liquid in other ways.Caffeinated drinks such as tea,coffee and cola,and alcohol can help reach the daily total if they don't drink too much,though these drinks help the production of urine . Less well known are the dangers of drinking too much water,causing water poisoning,low salt levels and even death. The review of research by Dan Negoianu,from the University of Pennsylvania,found that not a single study included the suggestion of drinking eight glasses of water a day.Although one small study suggested that drinking water could result in fewer headaches,the results were not very important.However,the benefits of drinking some water to prevent a pain in head after drinking too much alcohol are.separately,proved to be true. No studies showed any advantages to the color1 of the skin because of the increased water taken into bodies.Dehydration can make skin less pleasant,but there was no clear evidence to support the idea that water helps people keep a youthful appearance.The researchers also found no evidence that drinking lots of water does some good to the body's organs . The writer's main purpose of writing this passage is to _ . A) persuade people to drink different kinds of water B) warn people of the danger of drinking much water C) tell people drinking much water is not as healthy as is considered D) help people realize the importance of drinking enough water every day

As a teen, you're going through big changes physically and mentally. Your interests are expanding. And your desire to take control of your own life is growing. Here is the challenge: Kids need to explore the world in new ways, and parents need to protect them from the dangers that are out in that world. These conflicts can easily set off fireworks in otherwise calm houses. Sometimes conflicts can't be avoided. But by paying attention to the building blocks of successful relationships, you can work towards making home a happy and healthy place for you and your parents. For instance, try to find a time to talk when your parents are not angry, tired, distracted, or hungry. A good time to talk is when you're all relaxed . Timing is everything.

Listen to what your parents are saying, and repeat it back to them. This shows them that you're listening. It also gives them a chance to clear things up if you're not on the same page.

Ques: Many Americans have been leaving their cars at home and riding to work on bicycles. Andy Clark is the leader of the League of American Bicyclists. His group supports bicycling for fun, fitness and transportation. Clark says this is good news for the environment. He says riding a bicycle to work does not burn fossil fuel or creates dangerous pollutions. Experts say the effects are the most important on short trips. The Department of Transportation says fifty percent of Americans drive eight kilometers or fewer to work. Shorter car trips set out more pollution into the air for each kilometer drive. This is because the car engine will set out the harmful air when it warms up before it can work well. James, a members of Congress , is a strong supporter of bicycle use. He says cities, counties, state governments and state highway transportation agencies are planning the roadways of the future. They are creating roads and paths for bicycles in cities and between communities.

Does it feel right? This is an excerpt from Oprah Winfrey's 2008 Stanford Commencement Address: A year after I left college, I was given the opportunity to co-anchor the 6 o'clock news in Baltimore...Yet, it didn't feel right. The first sign, as President Hennessy was saying, was when they tried to change my name. The news director said to me at the time: "Nobody's going to remember Oprah. So, we want to change your name. We've come up with a name we think that people will remember and people will like. It's a friendly name: Suzie."... I grew up not loving the name, but once I was asked to change it, I thought, well, it is my name and do I look like a Suzie to you? So, I thought, no, it doesn't feel right. I'm not going to change my name. And if people remember it or not, that's OK. And then they said they didn't like the way I looked... So, they sent me to a salon where they gave me a perm , and after a few days all my hair fell out and I had to shave my head. And then they really didn't like the way I looked, because now I am black and bald and sitting on TV. Not a pretty picture. But even worse than being bald, I really hated, hated, hated being sent to report on other people's tragedies as a part of my daily duty, knowing that I was just expected to observe, when everything in my instinct told me that I should be doing something, (and that) I should be lending a hand... It felt right. And that's where everything that followed for me began. And after eight months, I lost that job. They said I was too emotional. I was too much. But since they didn't want to pay out the contract, they put me on a talk show in Baltimore. And the moment I sat down on that show, the moment I did, I felt like I'd come home. I realized that TV could be more than just a playground, but a platform for service, for helping other people's lives improve. And the moment I sat down, doing that talk show, it felt like breathing. And I got that lesson. When you're doing the work you're meant to do, it feels right and every day is a... What was the most important reason for why Oprah hated her job reporting the news? A) Reporting tragedies all day made her sad. B) She didn't like just standing around and talking. C) She hoped she could decide what to report. D) She was asked to change her name and shave her hair off.
