People who cannot tell all colors apart are said to be color-blind. Most color-blind people can see yellows and blues, but confuse reds with green. It is very rare for a person to be blind to all colors, but they may see everything in shades of black, white and gray.
It is interesting to point out that many color-blind people don’t even realize that they are color-blind, they don’t know that the colors they are seeing and naming are not the actual colors that people with normal vision can see. This can be dangerous when a color-blind person confuses the red and green of a traffic light.
Color blindness is thought to be inherited(遗传)and although doctors have tested color blindness, there is no cure to treatment for it.

People born in winter are more likely to suffer mental health disorders, according to a recent study carried out by researchers at Vanderbilt University in Tennessee.
Researchers raised baby mice from birth to weaning (断奶) in either “summer” light cycles of 16 hours of light and 8 hours of dark or “winter” cycles of 8 hours of light and 16 hours of dark. A third group experienced 12 hours of light and 12 hours of dark a day.
Then half the winter mice stayed in a winter cycle, while half switched to a summer schedule. The summer mice were similarly split. The mice raised in equal periods of light and dark were split into three groups, one of which stayed on the 12­hour schedule, one of which joined the winter group, and one of which joined the summer group.
After 28 days, it turns out the summer­born mice behaved the same whether they stayed on the summer cycle or switched to winter. But among the winter­born mice, those stayed in winter kept their previous schedule, while those that switched to summer stayed active for an extra hour and a half, which indicates that mice born and weaned in a winter light cycle showed dramatic disruptions in their biological clocks.
The finding is the first of its kind in mammals, and it could explain why people born in winter are at higher risk for mental health disorders including bipolar depression, schizophrenia and seasonal affective disorder.
“We know that the biological clock regulates mood in humans,”said study researcher McMahon. “If the mechanism (机制) similar to the one that we found in mice operates in humans, then it could not only have an effect on a number of behavioral disorders, but also have a more general effect on personality.”
小题1:How many groups of mice are there finally in all in the experiment?
A.Four.B.Five.C.Six. D.Seven.
小题2:What's the main idea of the text?
A.The biological clock regulates mood in humans.
B.People born in winter are at higher risk for physical health disorders.
C.Being born in winter has a negative effect on people's mental health.
D.The length of light will influence the behavior of the mice.
小题3:The underlined word “split”(Paragraph 3) can be replaced by ________.
A.endedB.tornC.hitD.divided
小题4:Who is the appropriate reader of the passage?
A.A job­hunter.B.A student in the university.
C.A newly­married couple.D.An experienced dentist.
Doctors in Britain are warning of an obesity time bomb, when children who are already overweight grow up. So, what should we do? Exercise more? Eat less? Or both? The government feels it has to take responsibility for this expanding problem.
The cheerful Mr. Pickwick, the hero of the novel by Charles Dickens, is seen in illustrations as someone who is plump and happy. In 18th century paintings, beauty is equated (使…等同) with rounded bodies and soft curves. But nowadays being overweight is seen as indicating neither a cheerful character nor beauty but an increased risk of heart disease, stroke and diabetes.
So what do you do? Diet? Not according to England's chief medical officer, Sir Liam Donaldson. He says that physical activity is the key for reducing the risks of obesity, cancer and heart disease. And the Health Secretary John Reid even said that being inactive is as serious a risk factor in heart disease as smoking.
So, having bought some cross trainers, how much exercise should you do? According to Sir Liam Donaldson, at least 30 minutes of moderate activity five days a week. Is going to the gym the answer? Luckily for those who think that running machines are boring, the Health Development Agency believes that physical activity that fits into people's lives may be more effective. They suggest taking the stairs rather than the lift, walking up escalators, playing active games with your children, dancing or gardening. And according to a sports psychologist, Professor Biddle, gyms "are not making the nation fit", and may even cause harm.
There's new scientific evidence that too much exercise may actually be bad for you. Scientists at the University of Ulster have found that unsuitable exercise releases dangerous free radicals that can adversely (oppositely) affect normal function in unfit people. The only people who should push their bodies to that level of exercise on a regular basis are trained athletes.
So, should we forget about gyms and follow some expert's advice to reduce sedentary (久坐不动的) activities and increase exercise in our daily life? After all, getting off the bus a stop early and walking the rest of the way can't do any harm! One final thought. How come past generations lacked gym facilities but were leaner and fitter than people today? 
小题1:Mr.Pickwick and the paintings of the 18m century are used as examples to show that_____.
A.beauty should be overweight

Although there is no possibility of living completely free of stress , it is possible to prevent stress as well as reduce its effect when it can’t be avoided. The US Department of Health and Human Services offers the following suggestions for the ways to deal with stress.
Try physical activity
When you are nervous, angry or upset, try reducing the pressure through exercise of physical activity. Running, walking, playing tennis or working in your garden are just some of the activities you might try. Physical exercise will relieve your anxiety and worry and help you to relax. Your body and your mind will work together to ease the stress in your life.
Share your stress
It helps to talk to someone about your anxiety and worries. Perhaps a friend, family member, teacher or even your leader can help you a better view of what is troubling you. If you feel your problem is serious, you might seek professional help from psychologist or a doctor. Knowing when to ask for help is an important step in avoiding serious problem later
Take care of yourself
You should make every effort to eat well and get enough rest. If you easily get angry and cannot sleep well enough, or if you are not eating properly, it will be more likely that you will fall into stressful situations. If stress repeatedly keeps you from sleeping, you should consult a doctor
Make time for yourself
Schedule time for both work and entertainment. Don’t forget, play can be just as important to your over-all well-being as work. You need a break from your daily routine to just relax and have fun. Go window-shopping or work on a hobby. Allow yourself at least a half hour each day to do something you enjoy.
Make a list of things you need to do
Stress can result from disorganization and a feeling that “there is so much to do, and not enough time.” Trying to take care of everything at once can be too much for you and as a result, you may not achieve anything. Instead, make a list of everything you have to do, then do one thing at a time, checking off each task as it is completed. Set out to do the more important tasks first.
Go ahead and cry
A good cry can a healthy way to bring relief to your anxiety. It might even help you avoid a headache or other physical effect of anxiety and stress

The World Health Organization (WHO) planned to study the relationship between the eating habits of the people and the disease. Two doctors were chosen to make the study. They flew to Africa south of the Sahara and during the next two months visited ten countries. They found that serious diseases of poor eating, often mistaken for other diseases, existed in all parts of Africa. The diseases were similar and could therefore all be named kwashiorkor. The diseased children are usually from one to four years old. As the illness progresses, the child’s stomach becomes swollen by liquid collecting in the body. The skin changes color and may break out in open sores(疼痛). The hair changes color and starts to fall out. The patient loses all interest in his surroundings and even in food, and becomes so weak that he wants to lie down all the time. Stomach liquids are no longer produced.
The doctors reasoned that kwashiorkor was found in the young children of this age in many parts of Africa because of lack of milk or meat. Their mothers, after stopping their breastfeeding, gave them foods full of starches(淀粉)instead of greatly needed proteins. They found that the addition of milk to the food of the children suffering from kwashiorkor saved many lives.
The unbelievable thing about kwashiorkor is that the very existence of the disease—which has been killing thousands of children for centuries—was not even recognized in Latin America as recently as ten years ago. The deaths of those children were mistakenly listed as due to other diseases. It was the WHO’s work in Africa that led to the discovery of the problem in Central America.

D.Taking medicine full of proteins.
小题4:What’s the best title for the article?
A.Milk and Meat Are Daily Necessities
B.Kwashiorkor and Improper Eating Habits
C.A New Form of Illness in Africa and Latin America
D.A Case of Eating Habits
The Healthy Habits Survey shows that only about one third of American seniors have correct habits. Here are some findings and expert advice.
1. How many times did you brush your teeth yesterday?
Finding:A full 33% of seniors brush their teeth only once a day.
Step:Remove the 300 types of bacteria in your mouth each morning with a battery-operated toothbrush.
Brush gently for 2 minutes, at least twice a day.
2. How many times did you wash your hands or bathe yesterday?
Finding:Seniors, on average, bathe fewer than 3 days a week. And nearly 30% wash their hands only 4 times a day----half of the number doctors recommend.
Step:We touch our faces around 3,000 times a day-often inviting germs(病菌)to enter our mouth, nose, and eyes. Use toilet paper to avoid touching the door handle. And, most important, wash your hands often with hot running water and soap for 20 seconds.
3. How often do you think about fighting germs?
Finding:Seniors are not fighting germs as well as they should.
Step:Be aware of germs. Do you know it is not your toilet but your kitchen sponge(海绵)that can carry more germs than anything else? To kill these germs, keep your sponge in the microwave for 10 seconds.

In the past, the affairs happening inside one country had little influence on other countries, even the neighboring ones. Therefore, incidents of food safety only affected and spread within one country, one city, one island or one village. However, with globalization, goods and products can almost flow freely between countries, regions, and continents. So the food safety problem is therefore no longer a national or regional issue, but rather a global one.
In 1997, Avian Influenza caused widespread panic in Hong Kong.It is said that the Avian Influenza originated from Shenzhen. Some Hong Kong people blamed the chicken farm staff on the mainland for the outbreak. The staff was accused of not thoroughly checking the health condition of the chicks under their care. It resulted in Hong Kong people's anger towards chicken farm staff in Shenzhen, whose supposed negligence(疏忽)contributed to the later spread of Avian Influenza in Hong Kong.
Worse still, in Germany, people have been warned not to eat cucumbers until tests can identify the source of a deadly E. coli outbreak. The scare has spread across Europe, with 16 people so far having been killed.In many people's minds, European countries have the strictest standards and checking procedures on their food safety. But the E. coli cucumber incident brought home the reality that it was not an effective defense against such an outbreak.
These diverse food safety issues from various parts of the world are enough evidence that food safety problem is not endemic in China. In fact, food safety is not even directly related to the development level of a place, thanks, no doubt, to the connectivity of our age. If we do not maintain our vigilance(警惕), people's confidence in food safety can be destroyed instantly—even in a developed country
小题1:Which of the following is true according to the passage?
A.Nowadays, food safety incidents spread inside one country
B.In 1997, Avian Influenza caused great fear in Hong Kong
C.16 Germans died of deadly E. coli after eating cucumbers

小题3:We can infer from the passage that ______
A.food safety problems spread from one country to another
B.the staff of a Shenzhen chicken farm caught Avian Influenza
C.the strictest standards protected European people from getting E. coli
D.China is a country where food safety problem is related to people's age
小题4:Which of the following would be the best title for the passage?

B.Cucumbers Are Popular in European Countries
C.Avian Influenza Originated from Shenzhen
D.Food Safety Issues Are Various from Country to Country
Given that many people's moods (情绪)are regulated by the chemical action of chocolate, it was probably only a matter of time before somebody made the chocolate shop similar to a drug store of Chinese medicine. Looking like a setting from the film Charlie&the Chocolate Factory, Singapore's Chocolate Research Facility (CRF) has over 100 varieties of chocolates.its founder is Chris Lee who grew up at his parents' corner store with one hand almost always in the jar of sweets.
If the CRF seems to be a smart idea, that's because Lee is not merely a seasoned salesperson but also head of a marketing department that has business relations with big names such as Levi's and Sony. That idea surely results in the imagination at work when it comes to making different flavored(味道)chocolates.
The CRF's produce is "green". made within the country and divided into 10 lines, with the Alcohol Series being the most popular. The Exotic Series一with Sichuan pepper, red bean (豆).cheese and other flavors一also does well and is fun to taste. And for chocolate snobs,who think that they have a better knowledge of chocolate than others, the Connoisseur Series uses cocoa beans from Togo, Cuba, Venezuela , and Ghana, among others.
小题1:What is good about chocolate?
A.It serves as a suitable gift.
B.It works as an effective medicine.
C.It helps improve the state of mind.
D.It strengthens business relations.
小题2:Why is Chris Lee able to develop his idea of the CRF?
A.He knows the importance of research.
B.He learns form shops of similar types.
C.He has the support of many big names
D.He has a lot of marketing experience.
小题3:Which line of the CRF produce sells best?
A.The Connoisseur Series.
B.The Exotic Series.
C.The Alcohol Series.
D.The Sichuan Series.
小题4:The words "chocolate snobs" in Paragraph 3 probably refer to people who
A.are particular about chocolate
B.know little about cocoa beans
C.look down upon others
D.like to try new flavors
As an English saying goes, “Laughter is the best medicine.” Until recently, few people took the saying seriously. Now however, doctors have begun to look into laughter and the effects it has on the human body. They have found that laughter really can improve people’s health.
Tests were carried out to study the effects of laughter on the body. People watched funny films while doctors checked their heart, blood pressure, breathing and muscles. It was found that laughter has similar effects to physical exercise. It increases blood pressure, makes the heart beat quicker and makes people breathe deeper; it also works several groups of muscles in the face, the stomach, and even the feet. If laughter exercises the body, it must be beneficial.
Other tests have shown that laughter appears to be able to reduce the effect of pain on the body. In one experiment doctors produced pain in groups of students who listened to different radio programs. The group that tolerated (忍耐) the pain for the longest time was the group which listened to a funny program. The reason why laughter can reduce pain seems to be that it helps to produce a kind of chemical in the brain which diminishes both stress and pain.
As a result of these discoveries, some doctors in the United States now hold laughter clinics, in which they help to improve their patients’ condition by encouraging them to laugh. They have found that even if their patients do not really feel like laughing, making them smile is enough to produce beneficial effects similar to those caused by laughter.
小题1:Which of the following statements is NOT true according to the passage?  
A.Laughter can make people breathe deeper
B.Laughter can make you become old quickly.
C.Laughter helps to reduce pain.
D.Laughter, just like physical exercise, is good for our body.
小题2:The underlined word “diminishes” in the third paragraph means “_________”.  
A.delays B.preventsC.increasesD.reduces
小题3:Why do doctors hold laughter clinics? 
A.Because they want to earn more money.
B.Because they think they will help the patients recover from illnesses.
C.Because they want to improve their patients’ health.
D.Because they want their patients to laugh more.
小题4:According to the author, we should __________ in our life. 
A.laugh as much as possibleB.watch more funny films
C.smile all the timeD.spend time in the laughter clinics
小题5:What would be the best title for this passage?  
A.Both laughter and physical exercise are good for health.
B.Laughter clinics can help patients improve their condition.
C.Laughter can reduce the effect of pain.
D.Laughter is the best medicine.
