Having one of those days or weeks when everything seems to annoy you? Even if you do nothing about it, your bad mood(心情) 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 the bad mood.
Tune it out
Listening to your favorite music for a while can also make tension go away quickly, because music starts connection with past positive experiences we've had.
Give yourself a paper 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(悲觀的) 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 mood­lifters. These include deep breathing, stretching and visualizing(想像), all of which sound complicated(復(fù)雜的) but aren't. One easy way to visualize: close your eyes and picture a favorite place, such as the beach. Another simple way to distress is to make a to­do 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. The better choice? Research shows that carbohydrates, such as potatoes and pasta(面食), produce calming effects in people who have a desire for them.
小題1:Which of the following may help us stop a bad mood?

小題3:TV may not improve your mood because it ________.

A．shows what happens around you	B．does not energize you
C．reminds you of eating and drinking	D．produces a calming effect

小題4:Which would be the best title for this passage?

A．Energy Level and Stress	B．How to Beat a Bad Mood

Women who own cats are more likely to have mental health problems and kill themselves because they can be infected by a common parasite that can be caught from cat litter, a study has found.
Researchers found women infected with the Toxoplasma gondii (T. gondii) parasite(剛地弓形蟲(chóng)), which is spread through contact with cat waste or eating undercooked meat or unwashed vegetables, are at increased risk of attempting suicide.
The study involved more than 45,000 women in Denmark. About a third of the world’s population is infected with the parasite, which hides in cells in the brain and muscles, often without producing symptoms.
The infection, which is called toxoplasmosis(弓形蟲(chóng)病), has been linked to mental illness, such as schizophrenia(精神分裂癥), and changes in behavior.
The study’s senior author Doctor Teodor Postolache, an associate professor of psychiatry(精神病學(xué)) at the University of Maryland School of Medicine in the United States, said, “We can’t say with certainty that T. gondii caused the women to try to kill themselves, but we did find a predictive association between the infection and suicide attempts later in life that deserves additional studies.”
Doctor Albert Reece, vice president of medical affairs at the University of Maryland, said, “T. gondii infection is a major public health problem around the world, and many people don’t realize they’re infected.
“Dr Postolache is a leading expert on suicide neuroimmunology(神經(jīng)免疫學(xué)). Suicide is a critically important mental health issue. About one million people commit suicide and another 10 million attempt suicide worldwide each year. We hope that this type of research will one day help us find ways to save many lives that now end too early in suicide.”
Dr. Postolache’s research team at the University of Maryland was the first to report a connection between T. gondii and suicidal behavior in 2009. He is cooperating with researchers in Denmark, Germany and Sweden to confirm and investigate the way leading to this association.
The T. gondii parasite thrives in the intestines of cats, and it is spread through their waste. All warm-blooded animals can become infected through contact with it. Humans can become infected by changing their infected cats’ litter boxes, eating unwashed vegetables, drinking water from a polluted source, or by eating undercooked or raw meat.
Not washing kitchen knives after preparing raw meat before handling another food item also can lead to infection. Pregnant women can pass the parasite directly to their unborn babies and are advised not to change cat litter boxes to avoid possible infection.
Babies don’t produce antibodies to T. gondii for three months after they are born, so the antibodies present in their blood represented infection in the mothers. The scientists studied Danish health patients to determine if any of these women later attempted suicide, including cases of violent suicide attempts which may have involved guns, sharp instruments and jumping from high places.
The study found that women infected with T. gondii were one and a half times more likely to attempt suicide compared to those who were not infected, and the risk seemed to rise with increasing levels of the T. gondii antibodies.
Dr Postolache noted limitations to the study, such as the inability to determine the cause of the suicidal behavior.
The findings were published online in the Archives of General Psychiatry.

Cancer researchers urged people on Wednesday to take more vitamin D to lower risk of cancer， saying studies showed a clear link. "Our suggestion is for people to increase their intake， through diet or a vitamin supplement，" Dr. Cedric Garland said in a telephone interview.
Garland's research team reviewed 63 studies， including several large long-term ones， on the relationship between vitamin D and certain types of cancer worldwide between 1966 and 2004. "There's nothing that has this ability to prevent cancer，" he said， urging governments and public health officials to do more to fortify foods with vitamin D.Garland is part of a University of California at San Diego Moores Cancer Center team that published its findings this week online in the American Journal of Public Health.    Vitamin D is found in milk， as well as in some fortified orange juice， yogurt and cheeses， usually at around 100 international units （IU） a serving. People might want to consider a vitamin supplement to raise their intake to 1000 IUs per day， Garland said， adding that it was well within the safety guidelines established by the National Academy of Sciences.
The authors said that taking more vitamin D could be especially important for people living in northern areas， which receive less vitamin D from sunshine.
African Americans， who don't produce as much of the vitamin because of their skin colour， could also benefit significantly from a higher intake， the authors said.
小題1: According to the passage， people are advised to take more Vitamin D because_________.

How often do you sit still and do absolutely nothing? The usual answer these days is“never” or “hardly ever”. 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. There is no way to avoid it, since it takes many and varied forms-driving in traffic, problems with personal relationships are all different forms of stress. Stress, in fact, is not the “baddy” it is often reputed 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 sight of unusual difficulties. When exposed to stress, in whatever form, we react both chemically and physically. In fact we make a choice between “fight” or “fright” and in more primitive days the choice made the difference between life and death. The crisis we meet today are unlikely to be so extreme, but however little the stress, it involves the same response. All the energy is shifted to cope with the stress. It is when such a reaction lasts long, through continued exposure to stress, that health becomes endangered. Such serious conditions as high blood pressure and heart disease have established links with stress.
Stress in some people produces stomach disorders, while others experience tension headaches. Since we cannot remove stress from our 1ives, We need to find ways to cope with it.

C.O.P.D(慢性障礙性肺病) blocks air flow through the lungs. It makes breathing difficult. The leading cause of C.O.P.D. is cigarette smoking. Experts at the National Institutes of Health in the United States say there is no cure to the damage to the lungs.
Dawn Demeo is an assistant professor at Harvard Medical School in Boston, Massachusetts. She said, “By 2020, C.O.P.D. may be the third leading cause of death across the world.”
C.O.P.D. is a new name for emphysema（肺氣腫） and chronic bronchitis（慢性支氣管炎）. These are the two most common forms of the disease. Many people with C.O.P.D. have both of them. And Doctor Demeo says more women than men now die from the disease.
She is the lead author of a study by a team from Harvard’s Brigham and Women’s Hospital and the University of Bergen in Norway. The new study adds to findings that women may be more at risk than men from the damaging effects of smoking.
The team examined results from a Norwegian study of 954 people with C.O.P.D. Inga-Cecilie Soerheim co-wrote the team’s findings. Doctor Soerheim says they show that women suffered the same level of C.O.P.D.as men. But the female smokers were younger and had smoked a lot less.
The team also looked at two groups among the people in the study. These were people under the age of 60 and those who had smoked for less than 20 years. In both cases, women had more serious C.O.P.D. and a greater loss of lung function (功能）than men.
小題1:Which of the following statements about C.O.P.D is NOT true ______.
A. Cigarette smoking is likely to cause C.O.P.D.
B. C.O.P.D. makes it hard for a person to breathe

D．Business report

New research suggests that speaking more than one language may delay different kinds of dementia(癡呆), that is the loss of mental ability. In fact, researchers say, speaking two languages appears to be more important than the level of education in defending against dementias.
A study in India examined the effect of knowing more than one language in delaying the first signs of several dementias. Researchers studied nearly 650 people whose average age was 66. 240 of those studied suffered from Alzheimer's, the most common form of mental decline(下降). 391 of the subjects spoke two or more languages. Researchers found the dementias began about four-and-a-half years later in those who spoke two languages compared to those who spoke only one language. The level of education had no effect on the age at the first sign of dementia.
Thomas Bak, from the Center of Cognitive Aging at the University of Edinburgh in Scotland, who helped to organize the study, suggests that individuals who speak more than one language train their brains by moving back and forth between different words and expressions. He also believes this effort improves what scientists called executive(執(zhí)行的) functioning, which often weakens in people with dementias. He states that researchers found there was no extra gain in speaking more than two languages.
Mr Bak says it does not appear important whether you learn another language at a young age or later in life. It's not something that “you missed the boat when you do not do it as a baby.” It is something that is still quite useful and powerful when you do it as an adult.
小題1:The finding of the study is that________.

A．learning more than one language can cure dementias

B．speaking two languages may delay kinds of dementias

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（光澤）. 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.

Nuclear power’s danger to health, safety, and even life itself can be summed up in one word: radiation.
Nuclear radiation has a certain mystery about it, partly because it cannot be detected by human senses. It can’t be seen or heard, or touched or tasted, even though it may be all around us. There are other things like that. For example, radio waves are all around us but we can’t detect them, sense them, without a radio receiver. Similarly, we can’t sense radioactivity without a radiation detector. But unlike common radio waves, nuclear radiation is not harmless to human beings and other living things.
At very high levels, radiation can kill an animal or human being immediately by killing masses of cells in vital organs. But even the lowest levels can do serious damage. There is no levels of radiation that is completely safe. If the radiation does not hit anything important, the damage may not be serious. This is the case when only a few cells are hit, and if they are killed immediately. Your body will replace the dead cells with healthy ones. But if the few cells are only damaged, and if they reproduce themselves, you may be in trouble. They can grow into cancer. Sometimes this does not show up for many years.
This is another reason for some of the mystery about nuclear radiation. Serious damage can be done without the victim being aware at the time that damage has occurred. A person can be irradiated（輻射）and feel fine, then die for cancer five, ten, or twenty years later as a result. Or a child can be born weak as a result of radiation absorbed by its grandparents.     
Radiation can hurt us. We must know the truth.         
小題1:Which of the following statements is true?                   

A．Nuclear radiation is just like common radio waves.

B．Nuclear radiation can cause cancer to human beings.

C．Nuclear radiation can be detected by human senses.

D．Nuclear radiation can be safe to human beings if its level is low.

小題2:How can nuclear radiation kill an animal?                    

A．By damaging its heart.	B．By killing a few cells.
C．By hitting any place in its body.	D．By killing many cells in important organs.

小題3: If a human being is hit by nuclear radiation, he may _______.

A．die of cancer after many years	B．die immediately
C．have a child who may be born weak	D．a(chǎn)ll of the above

“If music is the medicine of the soul(靈魂), let it play on,” said a famous person. I think he said so because probably he got some help from music. Music has some strange abilities. Medical scientists have found that a person that feels stressed can actually listen to some kind of music and become well.
The researchers said that since stress comes as a result of life events such as starting a new family, starting a new business, and starting a new job, one can actually listen to good music and feel good because good music touches the human mind in a positive way. Music helps you to forget the life events that make you worried and remember the important events that once happened in your life.
Depression(抑郁) is a disease cause by stress, smoking, social problems and so on. Depression is also caused by problems such as failure in business. Depression may bring us weakness, headache, and loss of concentration. Good music makes one remember happy moments or good days. If you play music about love, it makes you feel like falling in love again though you may have had several upset experiences. And such good feeling make you healthy.
Anxiety(焦慮) is another health problem that can be controlled by music. Anxiety is a side effect of some major health problems such as cancer of the liver and cancer of the breast. Good music makes you feel relaxed and removes the pains from these diseases and you feel all right.
Good music can send you to sleep. And you need to know that sleep puts your body in a healthy condition. Sleep takes away the effects of stress, depression and anxiety from a person.
