Drinking eight cups or two litres of water a day is longstanding advice. But is there any scientific basis for it, asks Dr Chris van Tulleken.
You know those ads that remind us that even a small drop in hydration（水合作用） levels can massively affect performance so you need to keep hydrated with whatever brand of super drink they're selling?
They seem pretty scientific don't they? Man in white coat, athlete with electrodes attached and so on. And it's not a hard sell because drinking feels right - you're hot and sweating so surely replacing that fluid must be beneficial.
Well earlier this year sports scientists in Australia did an extraordinary experiment that had never been done before.This group wanted to find out what happened to performance after dehydration. So they took a group of cyclists and exercised them until they lost 3% of their total body weight in sweat.
Then their performance was assessed after rehydration with either 1) nothing, 2) enough water to bring them back to 2% dehydration or 3) after full rehydration.
So far nothing unusual, but the difference between this and almost every other study that's ever been done on hydration was that the cyclists were blind to how much water they got. The fluid was given intravenously without them knowing the volume.
This is vital because we all, and especially athletes, have such an intimate(密切的)psychological relationship with water consumption.
Remarkably, there was no performance difference between those that were fully rehydrated and those that got nothing. This study was part of a growing movement to "drink to thirst" which hopes to persuade athletes not to over hydrate with the potentially fatal consequence of diluting your sodium level, causing hyponatraemia.
Perhaps the result shouldn't be so surprising. Humans evolved doing intense exercise in extreme heat and dryness. We are able to tolerate losses in water relatively well whereas even slight over hydration can be far more dangerous. In simple terms, being too watery is as bad for you as being too concentrated.

Some people make you feel comfortable when they are around. You spend an hour with them and feel as if you have known them half your life. These people have something in common. And once we know what it is, we can try to do it ourselves.
How is it done? Here are several skills that good talkers have. If you follow the skills, they’ll help you put people at their ease, and make friends with them quickly.
First of all, good talkers ask questions. Almost anyone, no matter how shy he is, will answer a question. One well-known businesswoman says, “At business lunches, I always ask people what they did that morning. It’s a common question, but it will get things going.” From there you can move on to other matters—sometimes to really personal questions. And how he answers will let you know how far you can go.
Second, once good talkers have asked questions, they listen to the answers. This point seems clear, but it isn’t. Your questions should have a point and help to tell what sort of person you are talking to. And to find out, you really have to listen carefully and attentively.
Real listening at least means some things. First it means not to change the subject of conversation. If someone sticks to one topic, you can take it as a fact that he’s really interested in it. Real listening also means not just listening to words, but to tones of voice. If the voice sounds dull, then, it’s time for you to change the subject.
Finally, good talkers know well how to deal with the occasion of parting. If you’re saying good-bye, you may give him a firm handshake and say, “I’ve really enjoyed meeting you.” If you want to see that person again, don’t keep it a secret. Let people know what you feel, and they may walk away feeling as if they’ve known you half their life.
小題1:Asking questions might be a quite good and suitable way _______.
A．for you to make more and more new friends
B．to begin your business talks
C．to get the conversation going smoothly
D．for you to make a deep and lasting impression on others
小題2:After having asked somebody a question, it’ll be polite of you to _______.
A．make clear what kind of person he is
B．listen to his reply attentively
C．wait quietly and patiently for his answer
D．go on asking him more questions
小題3:Generally speaking, good talkers are persons who _______.
A．a(chǎn)re good at making any topic interesting
B．never talk too much or too little
C．a(chǎn)lways speak in a gentle way
D．know how and when they should change the topic of the talk
小題4:If you really take delight in meeting someone again, _______.
A．you may take him as your lifelong trustworthy friend
B．it seems necessary for you to let him know it
C．it’s proper for you to give him a second handshake
D．it’ll be helpful for you to have further understanding of him

As the pace of life continues to increase, we are fast losing the art of relaxation. Once you are in the habit of rushing through life, being on the go from morning till night, it is hard to slow down. But relaxation is essential for a healthy mind and body.
Stress is a natural part of everyday life and there is no way to avoid it. In fact, it is not the bad thing it is often supposed to be. A certain amount of stress is vital to provide motivation and give purpose to life. It is only when the stress gets out of control that it can lead to poor performance and ill health.
The amount of stress a person can withstand depends very much on the individual. Some people are not afraid of stress, and such characters are obviously prime material for managerial responsibilities, others lose heart at the first sign of unusual difficulties. When exposed to stress, in whatever form, we react both chemically and physically. In fact we make choice between "flight or fight" and in more primitive days the choices made the difference between life or death. The crises we meet today are unlikely to be so extreme, but however little the stress, it involves the same response. It is when such a reaction lasts long, through continued exposure to stress, that health becomes endangered. Since we can't remove stress from our lives (it would be unwise to do so even if we could), we need to find ways to deal with it.
46. People are finding less and less time for relaxing themselves because _____.
A. they regard working as their greatest enjoyment
B. they believe that work is superior to relaxation
C. they are traveling fast all the time
D. they are becoming busier with their work than ever before
47. According to the author, the most important character for a good manager is his _____.
A. strong will to hold out stress
B. knowing the art of relaxation
C. high sense of responsibility
D. having control over performance
48. Which of the following statements is TRUE, according to the passage?
A. We can find quite a few ways to avoid stress.
B. Stress is always harmful to people's health
C. It's easy to change the habit of keeping oneself busy with work.
D. Different people can bear different amount of stress.
49. In the last sentence of the passage, "do so" refers to _____.
A. "expose ourselves to stress"
B. "find ways to deal with stress"
C. "remove stress from our lives"
D. "establish links between diseases and stress"
50. According to the author, the right attitude toward stress is _____.
A. to avoid it                 B. to try to cope with it
C. to regard it as a vital motivation      D. to find some relaxation

Comera is the only place in the world which has a whistle(口哨)language. We do not know how and why it began because we do not know the complete history of the island. But we can certainly imagine the reasons for the beginning of the whistle language. There are many deep valleys on the island. A person on one side of valley cannot easily shout to a person on the other side. But he can whistle and be heard from four miles away, and the record is seven miles. The people who live on the island usually have good teeth, and this helps them to whistle well. They must also have good ears so that they can hear other whistlers.
We can understand why the whistle language continues. It is very useful on the island, and quite easy to learn. When somebody is hurt or ill, the whistle language takes the place of the telephone. If the sick person is a long way from the town, boys and men pass the news from one to another. A boy guarding cattle on a hillside whistles to a man fishing from his boat. The last one is able to describe the trouble fully and exactly to the doctor in town. People help each other in the same way when a car breaks or a cow is lost.
The whistle language is hundreds of years old, and probably it will continue to live for hundreds of years more. Radio and TV often kill the special ways of speaking in the different parts of a country. But on Comera island you are nobody if you cannot whistle. Perhaps soon after TV arrives on the island, the people there will be whistling the news and other facts and opinions.
小題1:If a person on Comera island is ill, 　　　.
A．others will phone the doctor in town
B．the whistle language will pass the news to the doctor
C．his family will take him to the doctor
D．people will take him to the hospital
小題2: From the passage we know radio and TV　　　at that time.
A．killed the special ways of speaking
B．whistled all the news and opinions
C．helped Comera people to communicate
D．did not appear on Comera island yet
小題3: Comera island is special in that　　　.
A．it attracts visitors every year
B．no visitors have ever been there
C．people there have special ears to hear whistles
D．people there use the whistle language to communicate with each other
小題4: Which of the following is NOT true according to the passage?
A．It is not easy for a person to live on Comera island if he cannot whistle.
B．The whistle language can only be found on Comera island.
C．The whistle language has been used for hundreds of years on the island, but will not be used any longer.
D．The record shows that one best whistler can be heard by others seven miles away.

Last summer, when Amanda R of Anaheim Hills, California, was running on a cross-country course with her team, she blacked out. “I got really dizzy,” she says. “I was out for a few minutes.” At first, Amanda thought she was just tired and didn’t think she had a health problem. She did go to the emergency room, where she was fine after tests, but she fainted (昏厥) again several days later as she was talking with her coach. Another doctor guessed that Amanda had blacked out “because we were in heat so much with not enough water and not enough of the right kind of foods”.
Teens often don’t want to stop and take a break or don’t notice when they start to feel bad, doctors say. However, paying attention if you’re not feeling well is important, as Amanda learned.
As a result, Amanda has changed her habits. “I drink a lot more water,” she says. “And put more salt in my diet. I’m eating more balanced meals.” Amanda advises teen athletes to trust their coaches and speak up when they’re not feeling well. “And recognize the difference between when you’re tired and when there’s something really wrong.”
Some people － up to 3 percent of the population － sweat too much, even in cold weather. The condition, called hyperhidrosis (多汗), can affect many parts and it often runs in families － hands down from generation to generation. Too much sweating over the whole body could be a symptom of another medical condition. Doctors aren’t sure what causes hyperhidrosis, but using special medications or other treatments can help.
小題1:What caused the happening mentioned in the passage during Amanda’s running?
A．She couldn’t breathe in enough air in the race.
B．She didn’t eat anything before the race.
C．She had been running all summer without a rest.
D．She neither drank enough water nor ate enough of the right kind of foods.
小題2:What can we infer from Paragraph 4?
A．There is no need to worry when sweating too much, even in cold weather.
B．Hyperhidrosis may have a bad effect on your health.
C．Doctors have discovered why people get hyperhidrosis.
D．Hyperhidrosis is a serious disease and no treatment can help.
小題3:The purpose of writing this passage is to____________.
A．tell teens the proper ways to take exercise in summer.
B．tell teens not to run in hot summer.
C．tell teens to pay attention to hyperhidrosis in the summer exercise
D．tell teens how to keep healthy.

When you think of the tremendous technological progress we have made, it’s amazing how little we have developed in other respects. We may speak contemptuously of the poor old Romans because they relished the orgies of slaughter that went on in their arenas. We may despise them because they mistook these goings on for entertainment. We may forgive them condescendingly because they lived 2000 years ago and obviously knew no better. But are our feelings of superiority really justified? Are we any less blood-thirsty? Why do boxing matches, for instance, attract such universal interest? Don’t the spectators who attend them hope they will see some violence? Human beings remains as bloodthirsty as ever they were. The only difference between ourselves and the Romans is that while they were honest enough to admit that they enjoyed watching hungey lions tearing people apart and eating them alive, we find all sorts of sophisticated arguments to defend sports which should have been banned long age; sports which are quite as barbarous as, say, public hangings or bearbaiting.
It really is incredible that in this day and age we should still allow hunting or bull-fighting, that we should be prepared to sit back and watch two men batter each other to pulp in a boxing ring, that we should be relatively unmoved by the sight of one or a number of racing cars crashing and bursting into flames. Let us not deceive ourselves. Any talk of ‘the sporting spirit’ is sheer hypocrisy. People take part in violent sports because of the high rewards they bring. Spectators are willing to pay vast sums of money to see violence. A world heavyweight championship match, for instance, is front page news. Millions of people are disappointed if a big fight is over in two rounds instead of fifteen. They feel disappointment because they have been deprived of the exquisite pleasure of witnessing prolonged torture and violence.
Why should we ban violent sports if people enjoy them so much? You may well ask. The answer is simple: they are uncivilized. For centuries man has been trying to improve himself spiritually and emotionally – admittedly with little success. But at least we no longer tolerate the sight madmen cooped up in cages, or public floggings of any of the countless other barbaric practices which were common in the past. Prisons are no longer the grim forbidding places they used to be. Social welfare systems are in operation in many parts of the world. Big efforts are being made to distribute wealth fairly. These changes have come about not because human beings have suddenly and unaccountably improved, but because positive steps were taken to change the law. The law is the biggest instrument of social change that we have and it may exert great civilizing influence. If we banned dangerous and violent sports, we would be moving one step further to improving mankind. We would recognize that violence is degrading and unworthy of human beings.
小題1:It can be inferred from the passage that the author’s opinion of nowadays’ human beings is
A．not very high. B．high.
C．contemptuous. D．critical.
小題2:The main idea of this passage is
A．vicious and dangerous sports should be banned by law.
B．people are willing to pay vast sums money to see violence.

小題3:That the author mentions the old Romans is
A．To compare the old Romans with today’s people.
B．to give an example.
C．to show human beings in the past know nothing better.
D．to indicate human beings are used to bloodthirsty.
小題4:.How many dangerous sports does the author mention in this passage?
A．Three. B．Five.
C．Six. D．Seven.
小題5:The purpose of the author in writing this passage is
A．that, by banning the violent sports, we human beings can improve our selves.
B．that, by banning the dangerous sports, we can improve the law.
C．that we must take positive steps to improve social welfare system.
D．to show law is the main instrument of social change.

Now Hear This
What do former American president Bill Clinton and rock musician Pete Townshend have in common.'? Both men have hearing damage from exposure to loud music, and both now wear hearing aids as a consequence. As a teenager, Clinton played saxophone in a band. Townshend, who has the more severe hearing loss, was a guitarist for a band called the Who. He is one of the first rock musicians to call the public's attention to the problem of hearing loss from exposure to loud music.
Temporary hearing loss can happen after only 15 minutes of listening to loud music. One early warning sign is when your ears begin to feel warm while you listen to music at a rock concert or through headphones. One later is that an unusual sound or a ringing is sometimes produced in your head after the concert.
"What happens is that the hair cells in the inner ear are damaged, but they're not dead," says physician and ear specialist Dr. Sam Levine. According to Dr. Levine, if you avoid further exposure to loud noise, it's possible to recondition the cells somewhat. However, he adds, "Eventually, over a long period of time, hair cells are permanently damaged." And this is no small problem.
What sound level is dangerous? According to Dr. Levine, regular exposure to noise above 85 decibels (分貝) is considered dangerous. The chart below offers a comparison of decibel levels to certain sounds. Here's another measurement you can use. If you're at a rock concert and the music is so loud that you have to shout to make yourself heard, you' re at risk for hearing loss. That's when wearing protective devices such as earplugs becomes critical.
The facts are pretty frightening. But are rock bands turning down the volume.'? Most aren't. "Rock music is supposed to be loud," says drummer Andrew Sather.  "I wouldn't have it any other way. And neither would the real fans of rock. "
Continued exposure to loud music and the failure to wear earplugs can lead to deafness, according to Dr. Levine. He states, "There's no cure for hearing loss. Your ears are trying to tell you something. That ringing is the scream of your hair cells dying. Each time that happens, more and more damage is done. "
Levels of Common Noises
Normal conversation                           50 — 65 dB
Food blender                                  88 dB
Jet plane flying above a person standing outside      103 dB
Rock band during a concert                      110 — 140 dB
小題1:From Paragraph 1, we can learn that                   .
A．loud music is a major cause of hearing loss
B．famous people tend to have hearing problems
C．teenagers should stay away from school bands
D．the problem of hearing damage is widely known
小題2:In Paragraph 3, the underlined word "recondition" means                .
A．not to be seenB．to fill with sound
C．to become larger in sizeD．to make good again
小題3:The purpose of the chart at the end of the article is to show                   .
A．a(chǎn) list of harmful sounds
B．the effect of rock concerts
C．the noise levels of familiar sounds
D．relationship between daily activities and hearing loss
小題4:Which of the following statements will Dr. Sam Levine probably agree?
A．When your ears feel warm, your hair cells are dead.
B．Drummer Andrew Sather gives good advice.
C．Many are taking the risk of losing hearing.
D．Doctors know how to cure hearing loss.

The World Health Organization says there has been a sharp increase in the number of over-weight children in developing countries. In African countries, the WHO says the number of over-weight or obese children is twice as high as it was 20 years ago. Around the world, about 43 million children under the age of five were overweight in 2013.
Overweight and obese children are more likely to become overweight and obese adults. The condition can generate serious health problems like heart diseases.
Francesco Branca is the director of the WHO Department of Nutrition for Health and Development.

They travel in cars or other vehicles more than on foot.
The WHO experts say to lower obesity rates is especially complex in countries that also deal with high rates of infectious(感染性的) diseases.
The WHO has some basic solutions for individuals and countries. The organization says you should lower your intake of fat, sugar, salt and processed food and eat more fruits,' vegetables and increase physical activity. The WHO says these actions are especially important for children.
And WHO expert Branca says mothers should breastfeed their babies for at least the first six months of life, if possible. More importantly, governments should consider providing vitamins for children and educational campaigns about problems linked to obesity would also help. In his view, government policies should deal with how food is marketed to children and food producers must balance quality and taste with the dangers of sugar, fat and salt.
