Getting rid of dirt, in the opinion of most people, is a good thing. However, there is nothing fixed about attitudes to dirt.
In the early 16th century, people thought that dirt on the skin was a means to block out disease, as medical opinion had it that washing off dirt with hot water could open up the skin and let ills in. A particular danger was thought to lie in public baths. By 1538, the French king had closed the bath houses in his kingdom. So did the king of England in 1546. Thus began a long time when the rich and the poor in Europe lived with dirt in a friendly way. Henry IV, king of France, was famously dirty. Upon learning that a nobleman had taken a bath, the king ordered that, to avoid the attack of disease, the nobleman should not go out.
Though the belief in the merit of dirt was long-lived, dirt has no longer been regarded as a nice neighbor ever since the 18th century. Scientifically speaking, cleaning away dirt is good to health. Clean water supply and hand washing are practical means of preventing disease. Yet, it seems that standards of cleanliness have moved beyond science since World War II. Advertisements repeatedly sell the idea: clothes need to be whiter than white, cloths ever softer, surfaces to shine. Has the hate for dirt, however, gone too far?
Attitudes to dirt still differ hugely nowadays. Many first-time parents nervously try to warn their children off touching dirt, which might be responsible for the spread of disease. On the contrary, Mary Ruebush, an American immunologist (免疫学家)， encourages children to play in the dirt to build up a strong immune system. And the latter position is gaining some ground.

Below is some advice on how to prevent cancer:
8 Ways to Avoid Cancer in Your Life
1. Eat Blueberries
Aside from being a healthy and delicious snack, blueberries contain pterostilbene, which has important colon（结肠） cancer-fighting prosperities. But wait, it gets better. Blueberries also offer a large dose of vitamins C (14 milligrams per cup). So at breakfast, try to take in a cup and a half of blueberries in your cereal or yogurt, or mixed with other berries.
2. Drink Pomegranate（石榴）Juice
The deep red juice of the pomegranate contains polyphenols, isoflavones and ellagic acid, which together create a powerful anticancer mixture. Most recently, researchers from the University of Wisconsin at Madison has discovered that 16 ounces of pomegranate juice per day also may inhibit the growth of lung cancer.
3. Relax
Feeling stressed or worried? Find ways to relax and you may reduce your chances of developing cancer. Purdue University researchers tracked 1,600 men over 12 years and found that half of those with high levels of worry died during the study period. Only 20 percent of the optimists died before the study were completed, while 34 percent of the extremely anxious men died of some type of cancer. Instead of stressing about the past or future, focus on the present and relax!
4. Take Selenium（硒）
Selenium is well known for its cancer-fighting properties. In a study of almost 1,000 men, researchers from the Journal of the National Cancer Institute found that when men with the lowest initial levels of selenium in their bodies received a daily supplement over a 4 year period, they cut their prostate（前列腺） cancer risk by a remarkable 92 percent. However, it is possible to get too much of a good thing, so monitor your intake of selenium-containing supplements, Brazil nuts, tuna, meats and grains carefully.
5. Eat Sushi（寿司）
Seaweed may not be your idea of a great snack, but it is high in fiber, calcium and iron, and dry, roasted seaweed sheets used in sushi provide the additional benefits of vitamins A and C. Sushi rolls are also high in protein— a typical spicy tuna roll has only 290 calories but packs 24 grams of protein. So don’t skimp（节省）on the Sushi!
6. Enjoy the Outdoors
Vitamin D causes early death of cancer cells. A study published in the American Journey of Clinical Nutrition reported that women who supplemented their diets with 1,000 international. Units of vitamin D every day had a 60 percent to 77 percent lower incidence of cancer ever a four-year period that did women taking a placebo(无效对照剂). Experts recommend supplementing your fun in the sun with 1,100 to 2,000IU of vitamin D each day.
7. Breathe Clean Air
There’s no question that secondhand smoke kills. A recent American Journal of Public Health study showed that nonsmokers working in smoky places had three times the amount of carcinogen（致癌物质） in their urine（尿） than nonsmokers working in smoke-free locations. What’s worse, their levels of the carcinogen rose 6 percent for every hour worked. Nine states have banned smoking in all workplaces, bars and restaurants. The message is clear: Do whatever you can to avoid the cloud of smoke.
8. Break a Sweat
Even a small amount of exercise can offer major cancer-fighting benefits. In a study of 29,110 men published in the International Journal of Cancer, men who exercised just once a week had a percent lower risk of metastasis(转移性) prostate cancer than men who didn’t work out at all. The better the frequency, duration and intensity of the exercise, the bigger the reduction in risk, according to the study.
【小题1】To prevent yourself from catching colon cancer, you should eat ____ as often as possible.
| A．sushi | B．blueberries | C．pomegranates | D．Vitamin D |
| A．he is very fond of exercise every day. |
| B．he is addicted to smoking |
| C．he is always feeling extremely stressed or worried |
| D．he likes to have meals in restaurants |
| A．have a daily supplement of vitamins B and C |
| B．try to ignore the secondhand smoking |
| C．take in as many selenium-containing supplements as possible |
| D．having exercise as often as possible |

Are you having too much salt? You might not think so, but people in China eat on average (平均) about 12 grams of salt each day, that is much higher than the 6 grams suggested by the World Health Organization. You could be eating too much without realizing it, because about 75% of the salt we eat is already in the food we buy, such as bread, sauces, soups and sausages.
What problems can eating too much salt cause? To answer that question, first let’s take a look at what salt is.
Salt is a chemical compound. It is made of sodium (钠) and chloride (氯化物). Salt is used to keep and flavor foods. A small amount of salt is important for good health because our bodies need sodium and chloride to work.
But past studies have found that people who eat more salt than they need tend to have high blood pressure. Eating too much salt has also been connected with other conditions, such as heart and kidney (肾) problems.
If you want to cut down on salt, the good news is, there are plenty of simple things to do. Here are some tips:
*Cut back on high salt foods.
Most foods contain some salt. But some foods such as cheese, bacon, pickles (泡菜), smoked fish and chips are almost always high in salt because of the way they are made. You can still enjoy them, but try to have these in smaller amounts, or eat them less often.
*Choose reduced salt bread and breakfast cereals.
Bread and breakfast cereals (谷物) are major source of salt in the diet, not that they’re necessarily high in salt but because we eat a lot of them. For these foods, there can be a really big difference between different types and brands. So next time you’re shopping, take the time to compare the salt levels on a few similar products. And always try to choose the ones lower in salt.
*Avoid adding salt to cooking and at table. Instead, you could use herbs and spices (香料) such as garlic (大蒜) and lemon juice to add flavor to meals.
【小题1】Many people in China don’t realize they are eating too much salt because ______.
| A．salty food tasted better than reduced salt food |
| B．they do not calculate the amount of salt they eat |
| C．about 3/4 of the salt we eat is already in the food we buy |
| D．few people experience problems from eating too much salt |
| A．cut back on food with less salt |
| B．eat less heavily salted food |
| C．eat as much reduced salt bread as is wanted |
| D．stop eating bread and breakfast cereals |
| A．To warn people of food containing too much salt. |
| B．To inform people of the right amount of salt taken each day. |
| C．To advise people to be careful about the amount of salt they eat. |
| D．To promote (促进) the right way to make reduced salt food. |

Tui Na and Your Emotional Health
In Traditional Chinese Medicine the body, mind and spirit cannot be divided and so the unique whole-body treatment in Tui Na can also be a useful treatment correcting any imbalances in the body's energy before symptoms and disease can develop. It also works to restore emotional harmony as well as physical health. This is why after a Tui Na treatment many people "feel good". Many people in China use Tui Na regularly to keep healthy and to deal with some specific illnesses.
Tui Na is performed on the clothed body and the patient is either lying on a couch or sitting on a chair. Therapists using a variety of strokes or movements will control the intensity and direction of pressure in an exact way. The unique rolling movement in Tui Na is one of the most difficult strokes to learn and students have to practice sometimes for many months on a rice bag before they are allowed to practice on the human body.
Stress
Tui Na is of course very useful for treating stress.
It distributes the energy around the whole body. It is believed that Tui Na moves the strong energy in the tense muscles to the weaker areas, thus making a more balanced body. When your Qi （energy in the body） flow is balanced you feel relaxed and comfortable. Tui Na is especially useful for stiff shoulders and tense neck muscles.
Emotions
In Traditional Chinese Medicine each major organ is linked to an emotion. By balancing the energy in the organ, the relevant emotion will be calmed. When your emotions are out of control, you would usually turn to your doctor or perhaps a psychotherapist. But perhaps some people would not like to be seeing a psychotherapist or feel nervous about discussing their problems with others. With Tui Na one does not need to tell the therapist anything one does not want to. The treatment of Tui Na can deal with the problem itself — although if one does need to talk, then the safe space is there to do so. An active dialogue between the therapist and the patient will help to get a better effect.
How the major organs rule your emotions
Each major organ — the heart, the stomach, the spleen, the liver, the bladder, the kidneys, the lungs, etc. — is linked to a relevant emotion.
The heart is linked to joy, excitement and sadness. If the heart is out of balance, the patient may dream a lot at night and often forget something important in the day.
The stomach and spleen are connected with too much thinking or worrying — over anxiety. When the stomach is out of balance there is often a lack of energy. The patient often feels very tired and has no interest in doing anything at all.
The liver and gall bladder are linked to anger. In Chinese Medicine the eyes are connected with the liver, and many people who suffer from anger often suffer from eye problems. The gall bladder rules decision-making and too much energy here can lead to rashness, while if there is too little it can bring about indecision. Where there is a history of depression, the therapist would look to the liver.
The bladder and kidneys are linked to fear of all kinds, from simple anxieties and phobias to vague fears and worries.
The lungs are connected with feelings of grief and sadness. When there is a history of grief, the therapist would look to the lungs.
Tui Na is used in almost all the hospitals in China and very popular among Chinese people. It is a useful and valuable method of restoring Qi balance, when emotional and physical health is out of balance. Tui Na is one of the remaining secrets of Chinese Medicine.

| D．Tui Na only makes people "feel good" but do not actually cure disease. |
| A．By linking the organ to an emotion. |

Nowadays, the food we eat seems to have great effects on our health. Although science has made enormous steps in making food more fit to eat, it has, at the same time, made many foods unfit to eat. Some research has shown that perhaps eighty percent of all human illnesses are related to diet and forty percent of cancer is related to the diet as well, especially cancer of the colon. Different cultures are more likely to cause certain different illnesses because of the food that is characteristic in these cultures.
That food is related to illness is not a new discovery. In 1945, government researchers realized that nitrates, commonly used to preserve color in meats, and other food additives, caused cancer. Yet, these carcinogenic additives remain in our food, and it becomes more difficult all the time to know which things on the packaging labels of processed food are helpful or harmful. The additives which we eat are not all so direct. Farmers often give penicillin to beef and living animals, and because of this, penicillin has been found in the milk of treated cow. Sometimes similar drugs are given to animals not for medical purposes, but for financial reasons. The farmers are simply trying to fatten the animals in order to obtain a higher price on the market. Although the Food and Drug Administration (FDA) has tried repeatedly to control these procedures, the practices continue.
【小题1】What is the best possible title of the passage?
| A．Drug and Food | B．Food and Health |
| C．Cancer and Health | D．Health and Drug |
| A．Some of the additives in our food are added to the food itself and some are given to the living animals |
| B．Researchers have known about the potential dangers of food additives for about sixty-eight years. |
| C．Drugs are always given to animals for medical reasons |
| D．Food may cause forty percent of cancer in world. |
| A．Because of science, diseases caused by polluted food have been virtually eliminated. |
| B．It has caused a lack of information concerning the value of food. |
| C．The scientists have preserved the color of meats, but not of vegetables. |
| D．Because of the application of science, some potentially harmful substances have been added to food. |
| A．They preserve the color of meats. |
| B．They preserve flavor in packaged foods. |
| C．They are the objects of research |
| D．They cause the animals to become fatter. |
| A．trouble-making | B．color-retaining |

Having one of those days – or weeks – when everything seems to annoy you? Even if you do nothing about it, your bad mood will probably go away after some time. But with a little effort, you can forget it much faster – often within a day or two.
◇Walk it off
Exercise is the most popular bad-mood buster. A person who’s in a bad mood has low energy and high tension. Taking a fast ten-minute walk, or doing some quick exercises can do wonders towards changing that bad mood.
◇Tune it out
Listening to your favorite music for a while can also make tension go away quickly, because music starts associations with past positive experiences we’ve had.
◇Give yourself a pep talk
Stop and listen to what’s on your mind. Bad moods are often started by too many negative thoughts. Write them all down on paper, the pessimistic messages you’ve been giving yourself and then give optimistic answers. ( “I still don’t have a job.” Vs “I have two interviews next week.”)
◇Reduce your stress
Relaxation techniques are wonderful mood-lifters. These include deep breathing, stretching and visualizing, all of which sound complicated but aren’t. One easy way to visualize: close your eyes and picture a favorite place, such as the beach. Another simple way to be against distress is to make a to-do list. One reason for being in a bad mood is feeling you have no options. By taking control over certain areas, you realize you’re not helpless. You can make changes in your mood and life.
◇Avoid things that won’t improve your mood.
TV may not help much: You need to increase your energy level and stimulate（刺激） your mind – something that the TV show “Neighbors” won’t do. And before you reach for that piece of cake and coffee, think about how mood and food are linked. Sugar and caffeine contribute to depressed moods. A better choice? Research shows that carbohydrates, such as potatoes and pasta（面食）,produce a calming effect in people who have a desire for them.
【小题1】Which of the following may help us stop a bad mood?
| A．Doing nothing about it. | B．Exercising and enjoying music. |
| C．Writing down negative thoughts. | D．Talking about it with neighbors. |
| A．It helps remove bad mood. | B．It brings us a new technique. |
| C．It is not complicated to do so. | D．It is an area to be easily controlled. |
| A．shows what happens around you | B．does not energize you |
| C．reminds you of eating and drinking | D．produces a calming effect |
| A．Energy Level and Stress | B．How to Beat a Bad Mood |
| C．Bad Mood and Our Life | D．How to Control Your Feeling. |

Children pushed in buggies which face away from their parents may suffer longterm emotional（情感的）and language problems，according to a study published on Friday.
The research，believed to be the first of its kind，found that children who were not facing the person pushing them were less likely to talk，laugh and communicate with their parents.
The findings were based on a study of 2,722 parents and babies and an experiment where 20 babies were wheeled in buggies for a mile，facing their parents for half the journey and facing away for the other half. Parents using facetoface buggies were twice as likely to talk to their children while the babies’ heart rates fell and they were twice as likely to fall asleep，showing that they were feeling relaxed and safe.
In addition，only one baby out of the 20 studied laughed while sitting in an awayfacing buggy.
“Our data(数据) suggests that for many babies today，life in a buggy is emotionally impoverished and possibly stressful. Stressed babies grow into anxious adults，” said Dr Suzanne Zeedyk，Developmental Psychologist at Scotland’s Dundee University who carried out the research.
The study，which was published by National Literacy Trust as part of its “Talk To Your Baby” campaign，found that 62 percent of all children observed travelled in awayfacing buggies.
Zeedyk said it would have a negative effect on babies’ development if they spent a long time in awayfacing buggies，which would be bad to their ability to communicate with their parent at a time when their brain was developing rapidly.
Laura Barbour of the Sutton Trust，a social mobility charity which funded the research，said buggy manufacturers(制造商) should look closely at the findings.
【小题1】Using awayfacing buggies may________.
| A．benefit both the babies and their parents |
| B．affect babies’ language ability permanently |
| C．help babies communicate with their parents |
| D．have positive effect on babies’ development |
| A．Parents may talk twice with the babies in awayfacing buggies. |
| B．The study suggests children feel relaxed and safe in buggies. |
| C．The samples (案例)of the study were 20 babies wheeled in buggies. |
| D．One of the 20 babies was twice as likely to fall asleep in buggies. |
| A．Best for Kids to Face Parents in Buggy |
| B．Best for Kids to Communicate with Parents |
| C．Stressed Babies Grow into Anxious Adults |
| D．Buggy Manufacturers Care about the Finding |

Living in a modern society has its advantages and disadvantages. One disadvantage is that you often have to live closer to other people than you would like to. Sometimes, your neighbors make noise that you are not comfortable with.
The best way to solve this problem is to talk with your neighbor first. You should be very polite and ask your neighbor if he knows how thin the walls of your homes are. This way doesn’t criticize(批评)his behavior; it simply points out that he may not realize how far his sound travels. Tell him that you know that sometimes you make noise as well, but that you do your best to keep it down. Often this will solve the problem right away, but sometimes the neighbor may become angry.
If your neighbor becomes angry with you, there are some more steps you can take. You might write a letter to the neighborhood committee. Make sure you write down the source of the noise and the time in the letter. They will review the situation and decide whether your neighbor is out of line. Some noise is considered to be reasonable, even if it bothers you. So you may prepare a good pair of earplugs(耳塞).
Even if your neighbor makes too much noise, you don’t have to live your life in discomfort. It’s always a good idea to be friendly with your neighbors. You may clean the rubbish in front of his door. He’s sure to appreciate behavior like this and be more open to your suggestions about noise level.
【小题1】 What is the first step to deal with the noisy neighbor?
| A．To buy a good pair of earplugs. |
| B．To offer suggestions to the neighbor. |
| C．To ask the neighborhood committee for help. |
| D．To tell the neighbor how bad his behavior is. |

The Green Microgym in Portland，Oregon has all the usual stuff you'd expect-sweaty people，loud music，smooth exercise equipment-but it has some extras as well. Everywhere you look，there are power wires. And these aren't the typical kind that let you surf the Web while you ride a spin cycle-although. you can do that too．The gym uses special exercise equipment that captures（捕获）the energy you create while riding, converts（转换）it into electricity and channels it into the power outlets（插座）．
The idea of using exercise equipment to produce electricity is not new. A gym in Hong Kong has been doing this since 2007. But clean (and healthy）energy is just now starting to catch on in U. S. gyms·"We have seen a significant increase in interest in the past six months，which is a good sign that fitness centers are ready to spend money on green technologies，” says Mike Curnyn，co-founder of the Green Revolution，a Connecticut-based firm that wires bikes into a central battery that can store energy.
The Green Microgym，first opened in 2008，has more than 200 members and is doing so well that owner Adam Boesel opened another one five miles from the original．Although membership costs about the same as ordinary gyms，customers can earn gift certificates from local businesses for watts produced while exercising．An average workout creates 37. 5 watt hours，which is enough to power a phone for a week．
Boesel uses spin bikes made by Resource Fitness，a Seattle company he co-owns，that captures energy produced from the flywheel. Wires send the converted AC current（交流电流）into any standard wall outlet-for this reason，the product line's name is Plug Out-and the energy created is used before the building draws power from the grid（电网）．Unlike the Green Revolution equipment，Plug Out machines cannot store extra energy. A third company，the Florida-based ReRev，is adding converters to a specific brand of spin bikes. But since the converters add＄1，000 to the price of the equipment，the ReRev and Green Revolution machines are at a disadvantage．
Resource Fitness，by contrast，sells its equipment for the same＄1，200 price as non- electricity-producing machines，removing the question of how long it will be until the energy savings pay for the cost of the unit．The company can afford to do this because its designs don’t call for the extra wiring needed for battery packs and large converters．It is also trying to price competitively with standard equipment so more gyms-and gym goers-will make the switch．
【小题1】Members of the Green Microgym earn gift certificates for_______．
| A．using the man-powered exercise equipment |
| B．saving electricity for local businesses |
| C．producing green electricity to power their phones |
| D．paying higher membership fees |
| A．they are easier to ride |
| B．they are more expensive |
| C．they don't have wires connected |
| D．they can not store extra electricity |
| A．People's unwillingness to go green． |
| B．The high cost of making it. |
| C．Safety problems concerning electricity. |
| D．Lack of certificates． |
| A．change to a different gym |
| B．use green exercise equipment |
| C．switch on the spin bikes |
| D．add a battery to the machine |
