You might think I'd have little in common with a camel, but we do share one useful skill: both of us can go for a very long time without water. Usually I start my day with a cup of tea, and then I might have a glass of water with my lunch and one with dinner, that's about a liter of liquid in 24 hours. It feels like plenty, but apparently it's not nearly enough.
After years of suffering headaches and poor digestion I spoke to a neurologist about my regular headaches and a nutritionist about my poor digestion, and both told me I should be drinking up to three liters of liquid a day for my body to function at its best. I decided to conduct an experiment. What would happen if I drank the recommended amount every day for a month?
The photograph of me taken the day I started this trial demonstrates(展示）perfectly and rather frighteningly what a lack of hydration does to a face. I am 42, but have to admit I look more like 52 in this picture, which is shocking. There are dark shadows under and around my eyes, which make me look exhausted, a profusion of wrinkles and strange reddish blotches, and my skin lacks any luster（光泽）. It looks dead. Even my lips look shriveled（枯萎的）. This is all classic evidence of poor hydration, apparently.
Every system and function in our body depends on water. It flushes toxins from the vital organs, carries nutrients to cells, provides a moist environment for ear, nose and throat tissues, and eliminates waste.
Not drinking enough means all these functions becomes damaged. So I decided to see how I would look and feel if I drank three liters of water every day for 28 days. The results were astonishing.

Different exercise types have different purposes and different benefits. One type of exercise may not accomplish all goals of being physically fit: a healthy heart, strong muscles and bones, and safety from injury. As a result, it is important to do enough types of exercise to have all the physical benefits. Here is a quick check sheet.
Aerobic Exercise: To have a strong and healthy heart, you need to do aerobic exercise. This means that you need to exercise yourself enough so that your heart rate, while exercising, is 65 percent to 85 percent of your maximum heart rate. If you don’t get your heart rate up within this level—you just aren’t working hard enough. Whatever you do, your heart rate needs to be 65 percent to 85 percent of your MHR for 20 to 30 minutes, at least 3 times a week. Typical types include:
* Running
* Walking (at least 4 to 4.5 mph)
* Swimming
* Bikingk3s5u
* Elliptical Training
* Yoga
Strength Training: To keep your muscles and bones strong, you need to do strength training. This comes in a variety of forms. Whatever you do, however, you need to train your muscles enough so that they are really tired by the end of each session. To see real benefits, make sure you are strength training 2 to 3 times a week for about 30 to 40 minutes. Typical types of strength training include:
* Weight Training
* Yoga
* Resistance Training
* Plyometrics
Flexibility Training: To keep your body flexible, reducing risk of injuries and pain in your joints and muscles, you need to do flexibility training. You should always aim to stretch every muscle after any exercise routine. Typical types of flexibility training include:
* Stretching
* Yoga
* Pilates
So next time you think that yoga 5 times a week will be enough, think about what it is really doing. Is it getting your heart rate up? Are you making up your strength? Are you keeping your muscles flexible?
【小题1】If your purpose is to _______, you can choose swimming as your exercise form.
| A．keep muscles and bones strong |
| B．build a strong and healthy heart |
| C．keep body flexible |
| D．reduce risk of injuries and pain in joints and muscles |
| A．Yoga is really better for people than running |
| B．The three kinds of training have links with one another |
| C．Flexibility training helps you build up your muscles |
| D．The more exercise you do, the better |
| A．meeting | B．gathering | C．term | D．period |
| A．how to build up our strength |
| B．how to choose an exercise type |
| C．how to find a good workout dealing with two or three of these goals |
| D．how to be more flexible |

Bad teeth can be painful and even be deadly. Infections of the gums(牙龈) and teeth can release bacteria into the blood system. Those bacteria can increase the chance of a heart attack or stroke and worsen the effects of other diseases. And adults are not the only ones at risk. For example, a 12yearold boy died when a tooth infection spread to his brain in 2007 in Washington. Experts said it might have been prevented had he received the dental care he needed.
Experts say good dental care starts at birth. Breast milk, they say, is the best food for the healthy development of teeth. Breast milk can help slow bacterial growth and acid production in the mouth. But dentists say a baby's gums and early teeth should be cleaned after each feeding by using a cloth with a little warm water. Experts say if you decide to put your baby to sleep with a bottle, give only water.
When baby teeth begin to appear, you can clean them with a wet toothbrush. Dentists say it is important to find soft toothbrushes made especially for babies and to use them very gently. The use of fluoride(氟化物) to protect teeth is common in many parts of the world. For example, it is often added to drinking water supplies. The fluoride mixes with enamel(釉质), the hard surface on teeth, to help prevent holes from forming.
But young children often swallow toothpaste when they brush their teeth. The American Academy of Pediatric Dentistry notes that swallowing fluoridated toothpaste can cause problems. So young children should be carefully watched when they brush their teeth. And only a small amount of fluoridated toothpaste, the size of a pea, should be used.
Parents often wonder what effect finger sucking might have on their baby's teeth. Dental experts generally agree that this is fine early in life. Most children stop sucking their fingers by the age of four. If it continues, experts advise parents to talk to their children's dentists or doctors. Because it could interfere_with the correct development of permanent teeth.
Dentists say children should have their first dental visit at least by the time they are one year old. They say babies should be examined when their first teeth appear—usually at around six months.
【小题1】According to the passage，what is the function of fluoride?
| A．Making the surface on teeth much cleaner. |
| B．Protecting gums from being infected. |
| C．Keeping holes on teeth from forming. |
| D．Slowing down bacterial growth and acid production. |
| A．do harm to | B．account for |
| C．contribute to | D．stand for |
| A．To warn us of the deadly infections of gums and teeth. |
| B．To introduce the advantages of fluoridated toothpaste. |
| C．To draw our attention to the dental care of young children. |
| D．To present the research results about dental care. |

Country-dwellers(农村居民) often say the constant noise, heavy traffic and crowds of the city would drive them mad. Well, they might be right, according to the latest research. City residents are more likely to develop mental illnesses than those who live in villages, a study has found.
Researchers from Cardiff university examined the lifestyles of more than 200,000 people in Sweden and found that those who lived in urban areas were more at risk from mental illnesses than people who lived in villages.
The experts don’t know exactly why this is but they suggest that town and city residents are more likely to be ostracized(排挤) by those around them. They are more likely to experience discrimination(歧视) if they do not fit in, which can lead to them feeling anxious and even developing mental illnesses.
Dr Stanley Zammit, who led the research said that people living in towns and cities are more likely to develop other mental illnesses that result in personality changes — a condition known as non-affective psychosis(非情感性精神病).
Earlier this year an official report found that village-dwellers live an average of two years longer than those living in towns and cities. According to figures from the Office of National Statistics in the UK, men who live in villages are likely to live for between 78 and 79 years, while those in towns and cities can expect to survive to an age of 76. Women on average survive to their 81st birthday in towns and cities, but live to between 82 and 83 in villages. The small marked town of Wimborne Minster in rural Dorset was named the healthiest place to live in.
【小题1】What is the passage mainly about?
| A．Country-dwellers are more likely to develop mental illnesses. |
| B．City-dwellers are more likely to develop mental illnesses. |
| C．Country-dwellers live longer than city-dwellers. |
| D．City-dwellers live longer than country-dwellers. |

| A．people like living in towns and cities |
| B．city-dwellers enjoy their peaceful city life |
| C．village-dwellers are more likely to be looked down upon by others |
| D．village-dwellers get along better with their neighbors than city-dwellers. |
| A．character change | B．temperature rise |
| C．pressure increase | D．energy weakening |
| A．women living in villages live the longest |
| B．women living in cities live the longest |
| C．men living in villages live the longest |

Imagine you are doing this reading in this text on the computer; what else are you doing? Maybe you’re eating a sandwich or drinking a cup of Starbucks. Should you eat while reading?
There aren’t many believable numbers, but we do know the number of people who eat while sitting in front of some type of screen is growing. A recent study found that 33 percent of families always have the TV on during meal times and another 27 percent people have it on at least half the time. Another 10 percent may be texting, emailing or talking on a cell phone while eating.
Any type of these behaviors is bad, considering the following evidence:
A Canadian study found that children who watch more than three hours of cartoons a day are 50 percent more likely to be fat than children who watch fewer than two hours. The researchers concluded that more than 60 percent of overweight incidents can be connected with screen watching too much.
A three-week study found that adults who usually play with smartphones less burned 119 more calories per day.
One Chicago researcher found that people eat more potato chips while reading online than when they have the laptop turned off.
There has been very little investigation(调查) into eating with your eyes staring at a screen or reading a book, but it is likely that his mindless eating is related to weight gain. Simply speaking, your brain has no idea what is going on with your mouth because it is occupied by other things. You don’t notice how full your stomach is, and you often don’t even notice the taste or the act of chewing and swallowing, as a result of which, developing an adapted dietary habit is a must.
【小题1】The author answers the question raised in the first paragraph with ________.
| A．stories and explanations | B．examples and investigations |
| C．an argument and evidence | D．facts and descriptions |
| A．Being focused while eating is a good way to have a good figure. |
| B．Adults’ weight is not affected by their eating habits. |
| C．There exist many investigations into eating while reading. |

LEEDS, England—A Leeds University psychology professor is researching a course to help dozens of Britons forgive their enemies.
“The hate we hold within us is a cancer.” Professor Ken Hart said, adding that holding in anger can lead to problems such as high blood pressure and heart disease.
More than 70 people have become volunteers in Hart’s first 20-week workshop in London—a course he says is the first of its kind in the world.
These are people who are sick and tired of living with a memory. They realize their bitterness is a poison they think they can pour out, but they end up drinking it themselves, said Canadian-born Hart.
The students meet in each group of eight to ten for a two-hour workshop with a director every two weeks.
The course, ending in July, is expected to get rid of the cancer of hate in these people. “People have lots of negative attitudes towards forgiveness,” he said, “People confuse forgiveness with forgetting. Forgiveness means changing from a negative attitude to a positive one.”
Hart and his team have created instructions to provide the training needed.
“The main idea is to give you guidances on how to look at all kinds of angers and how they affect you, and how to change your attitudes towards the person you are angry with,” said Norman Claringbull, a senior expert on the forgiveness project.
Hart said, “I believe forgiveness is a skill that can be taught, as these people want to get free of the past.”
【小题1】From this passage we know that ________.
| A．without hate, people will have less trouble connected with blood pressure and heart disease |
| B．people who suffer from blood pressure and heart disease must have many enemies |
| C．high blood pressure can only be cured by psychology professors |
| D．high blood pressure and heart disease are caused by hate |
| A．attend Hart’s course |
| B．persuade him or her to have a positive talk with you |
| C．never meet him or her any longer |

| A．meet their enemies |
| B．change their attitudes |
| C．enjoy the professor’s teaching |
| D．learn how to quarrel with others |
| A．meet in eight or ten groups |
| B．get rid of the illness of cancer |
| C．attend a gathering twice a month |

Putting in water fountains (饮水器) at schools, and teaching children about the health benefits of water, could reduce their risk of getting extra pounds, reports a new study that is published in the latest issue of the journal Pediatrics.
The findings are based on a survey in 32 elementary schools of two German cities, Dortmund and Essen. The researchers, led by Rebecca Muckelbauer, a nutritionist(营养学家) at the Research Institute of Child Nutrition Dortmund, weighed about 3,000 children, and asked them about their beverage consumption(饮料消费量).
At the beginning of the school year, the experts had water fountains added to 17 of the schools. The scientists also worked with teachers to carry out educational programs that promote the benefits of drinking water. In contrast to schools in the United States, there are very few schools in Germany that have water fountains.
At the beginning of the study, there were no big differences in the number of overweight children in the different groups. But by the end of the school year, children in the schools with water fountains were 31 per cent less likely to gain extra pounds, compared to kids who went to other schools, where water drinking was not encouraged.
Children in the schools with fountains increased their water consumption from about 3 up to 4 glasses a day, while those in the other schools continued to drink an average of 3 glasses. Over the research, the number of overweight kids upped from 384 to 385 out of 1,641 at the schools with water fountains. In comparison, the number of overweight kids at the other schools increased from 339 to 364 out of 1,309, Dr. Muckelbauer said.
The experts cannot make any final conclusions and explain why the students who were encouraged to drink water were less likely to gain extra weight. Dr. Muckelbauer noted that according to a few other studies, drinking of water increases the rate at which calories are burned, while some other research suggested that water may temporarily decrease appetite (食欲).
【小题1】What do we know about the survey from the passage?
| A．The teachers were also encouraged to drink water. |
| B．The students surveyed were all overweight. |
| C．It surveyed children in the countryside. |
| D．It lasted for a whole school year. |
| A．Drinking water certainly decreases appetite. |
| B．Further research is needed to confirm the finding. |
| C．The experts will encourage all the students to drink water. |
| D．Why students drinking more get less pounds will be clear soon. |
| A．Schools with water fountains |
| B．Drink more water and become thinner |
| C．Water fountains at schools help kids stay thin |

How often do you go on holiday? Going on holiday makes you feel good while you're there－you gain the health benefits for months, new research shows.
Jetting off to exotic destinations such as the Maldives cuts your blood pressure, helps you sleep better and bounce back from stress, it found. The benefits last at least a fortnight longer than the vacation and can be felt for months in some cases where it is claimed. Experts say workers should always take their full holiday entitlement each year－as many as one in three don't－to get the benefits.
The study compared key health markers in holidaymakers visiting Thailand, Peru or the Maldives, with people who stayed at home and continued working. The average blood pressure of those on holiday dropped by 6% while the workers saw their blood pressure rise by 2% over the same period. The sleep quality of holiday-makers improved by 17% while that of the non-holidaymakers deteriorated by 14%.
The study also found the ability of vacationers to recover from stress—known as the stress-resilience test－improved by 29%. There was a 71% fall in stress resilience scores among workers. Test showed a fall in blood glucose levels, reducing the risk of diabetes, trimmer waistlines and enhanced mood and energy levels, with the effects sustained for at least 2 weeks after returning home.
The Holiday Health Experiment was conducted by tour operator Kuoni and Nuffield Health, the UK's largest healthcare charity.
【小题1】 The author intends to tell us that _____.
| A．it is best to go to foreign countries like Maldives. |
| B．we had better go on holiday for the benefits of health |
| C．we have to go on holiday as much as possible |
| D．you'll certainly get depressed if you don't go on holiday |
| A．Two thirds | B．17% | C．One third | D．A quarter |
| A．remained | B．rose | C．improved | D．worsened |
| A．Holiday makers are more adaptable than non-holidaymakers. |
| B．The result of the study is mostly based on the description from the people involved. |
| C．The further you go, the better you benefit. |
| D．Most people like to stay at home during the holiday. |

The economic growth that many nations in Asia and increasingly Africa have experienced over the past couple of decades has transformed hundreds of millions of lives – almost entirely for the better. But there’s a byproduct to that growth, one that’s evident – or sometimes less than evident – in the smoggy, smelly skies above cities like Beijing, New Delhi and Jakarta. Thanks to new cars and power plants, air pollution is bad and getting worse in much of the world, and it’s taking a major toll (伤亡人数，代价) on global health.
How big? According to a new analysis published in the Lancet, more than 3.2 million people suffered deaths from air pollution in 2010, the largest number on record. That’s up from 800,000 in 2000. And it’s a regional problem: 65% of those deaths occurred in Asia, where the air is choked by diesel soot (内燃发动机烟雾) from cars and trucks, as well as the song from power plants and the dust from endless urban construction. In East Asia and China, 1.2 million people died, as well as another 712,000 in South Asia, including India. For the first time ever, air pollution is on the world’s top – 10 list of killers, and it’s moving up the ranks faster than any other factor.
So how can air pollution be so damaging? It is the very finest soot – so small that it roots deep within the lungs and from the enters the bloodstream – that contributes to most of the public – health toll of air pollution including death. Diesel soot, which can also cause cancer, is a major problem because it is concentrated in cities along transportation zones affecting overpopulated areas. It is thought to contribute to half the deaths from air pollution in urban centers. Fro example, 1 in 6 people in the U.S. live near a diesel – pollution hot spot like a rail yard, port terminal or freeway.
We also know that air pollution may be linked to other non – deadly diseases. Fortunately in the U.S. and other developed nations, urban air is for the most part cleaner than it was 30 or 40 years ago, thanks to regulations and new technologies like the catalytic converters (催化式排气净化器) that reduce automobile emissions. Governments are also pushing to make air cleaner – see the White House’s move last week to further tighten soot standards. It’s not perfect, but we’ve had much more success dealing with air pollution than climate change.
Will developing nations like India eventually catch up? Hopefully – though the problem may get worse before it gets better. The good news is that it doesn’t take a major technological advance to improve urban air. Switching from diesel fuel to unleaded (无铅燃油) helps, as do newer and cleaner cars which are less likely to send out pollutants. Power plants – even ones that burn mineral fuels like coal – can be fitted with pollution – control equipment that, at a price, will greatly reduce smog and other pollutants.
But the best solutions may involve urban design. In the Guardian, John Vidal notes that Delhi now has 200 cars per 1,000 people, far more than much richer Asian cities like Hong Kong and Singapore. Developing cities will almost certainly see an increase in care ownership as residents become wealthier – and that doesn’t have to mean deadly air pollution. Higher incomes should also lead to tougher environmental regulations, witch is exactly what happened in the West. We can only hope it happens before the death toll from bad air gets even higher.
【小题1】What tends to give rise to the highest death toll according to the passage?
| A．The lack of tight environmental protection standards. |
| B．The increasing numbers of the diesel cars and trucks. |
| C．The frighteningly high death rate from deadly cancer. |
| D．The world’s serious air pollution such as soot and dust. |
| A．consequence | B．solution | C．reform | D．design |
| A．the diesel soot is too small to be seen |
| B．the diesel soot is much too poisonous to breathe |
| C．the diesel soot roots in lungs and gets into blood |
| D．the diesel soot can also contribute to deadly cancer |
| A．the global economic growth is mainly to blame for air pollution and climate change |
| B．the developing countries are repeating the same mistakes as the developed ones made |
| C．the ecological situation and air pollution in India are becoming worse and worse |
| D．the unbeatable air is increasingly becoming a major killer throughout the world |
| A．the making of tougher environmental regulations alone is of little use |
| B．more sever regulations should be made to handle air pollution |
| C．the urban construction in western developed countries is the best choice |
| D．the pace of development has to be slowed down to reduce air pollution |
