Studies show that laughter is something that makes you feel calm or relaxed for both physical and psychological wounds though it may seem futile to laugh in the face of pain and fear.
When Dan Rather interviewed comedian Bill Cosby just one week after his son, Ennis, was killed, Cosby said, “I think it is time for me to tell people that we have to laugh. You can turn painful situations around through laughter. If you can find humor in anything, you can survive it.”
Call it a flashlight for dark times: laughter just seems to adjust attitude better than anything else. Inspirational speaker Steve Rizzo recalls a TV interview with an injured firefighter a few days after 9.11．The man had fallen more than 30 stories in one of the towers and had broken a leg. Everyone was crying, and the reporter asked, “How is it that you’ve come out of this alive?” He looked at her and without missing a beat, said, “Look, lady, I’m from New York and I’m a firefighter; that’ all you need to know.”
“Everyone laughed and though the laughter was only a couple of seconds,” says Rizzo. “Sometimes that’s all you need to catch your second breath. Laughter gives you that couple of seconds. You’re sending a message to your brain, and the message is: If you can still laugh even a little among the pain, you are going to be OK.”
Of course, there is a difference between laughing off a serious situation and laughing off the fear that results. The firefighter was doing the latter, states Rizzo, the author of Becoming a Humorous Being, and so should we. “If there is anything we have learnt from 9.11, it’s how precious life really is,” she says. “We have to send a message that our spirit won’t die. One important thing that unites us is our ability to laugh.”
小题1:The writer uses the examples of the comedian and the firefighter to show .

A．hopeless	B．useless
C．careless	D．worthless

小题4:From the passage, we can know that Americans are .

A．really inspired after 9.11	B．hardly united after 9.11
C．nearly surprised by 9.11	D．greatly hurt by 9.11

Britons Learn to Forgive
LEEDS, England—A Leeds University psychology(心理学) professor is teaching a course to help dozens of Britons forgive their enemies.
“The hatred (仇恨) 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 members 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 groups of eight to ten for a two-hour workshop with an adviser every fortnight.
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（混淆） 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 guidelines on how to look at various 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 he believes forgiveness is a skill that can be taught, as these people “want to get free of the past”.

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(刚地弓形虫), 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(弓形虫病), has been linked to mental illness, such as schizophrenia(精神分裂症), and changes in behavior.
The study’s senior author Doctor Teodor Postolache, an associate professor of psychiatry(精神病学) 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(神经免疫学). 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.

New research suggests that cutting daily sitting time to less than three hours might extend your life by two years.
“Humans were designed to move. But modern lifestyles and office jobs rarely encourage us to walk around,” says Peter Katzmarzyk, an expert at the University of Louisiana.
“Sitting is common in our lives today. We sit while we’re driving, eating and watching TV. And many of us sit for many hours at work.” Katzmarzyk said.
“We can’t throw away physical activity. It’s extremely important. We have 60 years of researchers showing us that.” Katzmarzyk said.
Katzmarzyk and other researchers are trying to discover how sitting all day affext our lifespans（寿命）.
“This is a relatively new area of study…Studies that have assessed the relationship between sitting and death or television viewing and death have been very rare in the last four or five years,” said Katzmarzyk.
Katzmarzyk and his colleagues analyzed data from these studies, which involved almost 167,000 adults. Then they turned to a government-run survey of Americans to find out exactly how much time people spend sitting and watching.
Not only did the team find that U.S. citizens could live longer by sitting less, they found that cutting TV time to less than two hours a day could add an extra 1.4 years to their lives.
People who’ve spent half their waking lives sitting down might well ask, “Is it ever too late to make a change?”
“We would say ‘No. It’s never too late.’ Physical activity is good for you at every age.” Katzmarzyk said.
Katzmarzyk says studying this problem has inspired his team to make a few changes in their own lives. They recommend a few simple changes: frequently getting up from your desk, taking walks at lunch time, and instead of e-mailing colleagues, walking over to their offices and talking face-to-face——all activities that can be enjoyable as well as life-extending.

American researchers say drinking tea may help strengthen the body’s defense system against infection. Doctors at Brigham and Women’s Hospital in Boston, Massachusetts, did the study. The team studied a chemical found in black, green, oolong and pekoe tea. This chemical is an amino acid called L-theanine. The scientists say it may increase the strength of gamma delta T cells. That’s the letter T, not the drink. Gamma delta T cells are part of the body’s defense.
First, the researchers mixed some of these cells with antigens found in the amino acid(氨基酸). Antigens help the body react to infection. Then the scientists added some bacteria. Within twenty-four hours, the cells produced a lot of interferon, a substance that fights infection. Cells not mixed with the antigens did not produce interferon.
In the second part of the study, eleven people drank five to six cups of black tea every day. Ten other people drank the same amount of instant coffee. That is dried coffee mixed with hot water.
Two weeks later, and again two weeks after that, the researchers tested the blood of all twenty-one people. They also looked at what happened when they added bacteria to the blood cells. They found that the tea drinkers produced five times more interferon after they started drinking tea. The coffee drinkers did not produce interferon.
Doctor Jack Bukowski led the study. He says the antigens added to the gamma delta T cells were responsible for the increased reaction to the bacteria. He says that the study also showed that the cells were able to remember the bacteria and fight them again the next time.
Earlier research already has found that tea can help prevent heart disease and cancer. Doctor Bukowski says the new study must be repeated by more people. “If the findings prove to be true,” he says, “then tea drinking might also help protect against bacterial infections.” He says the amino acid L-theanine could be removed from the tea and used as a drug to strengthen the body’s defenses.
小题1:We may know from the text that ______ can be found in different kinds of tea.

A．L-theanine	B．Gamma delta T cells
C．interferon	D．bacteria

小题2:Tea may help strengthen the body’s defense system because it helps ______.

小题3:According to Dr Bukowski, ______.

A．the findings of the study have already proved to be true

B．further study is needed to prove the findings true

C．he has taken some amino acid L-theanine from tea and made a drug with it

D．he is not sure whether tea help prevent heart disease and cancer

小题4:What would be the best title for this text?

A．Tea Is Better than Coffee	B．Our Body Needs Tea
C．Tea Can Help Prevent Cancer	D．Tea May Help Fight Infection

Health experts are calling for action to increase cancer care and control in the developing world. A medical research paper says cancer was once thought of as a problem mostly in the developed world. But now cancer is a leading cause of death and disability in poor countries as well. Experts from Harvard University and other organizations urge the international community to fight cancer actively, saying it should be fought in the way HIV/AIDS has been fought in Africa.
Cancer kills more than 7.5 million people a year worldwide. Almost two-thirds are in low-income and middle-income countries.
They discover cancer kills more people in developing countries than AIDS, tuberculosis (肺结核) and malaria (疟疾) combined. But the world spends only 5% of its cancer resources in those countries.
Felicia Knaul from Harvard Medical School was one of the writers of the paper. She was in Mexico when she was found to have breast cancer. She received treatment there and her experience showed her the sharp difference between the rich and the poor in treating breast cancer.
Felicia Knaul says, “And we are seeing how this is attacking young women. It’s the number two cause of death in Mexico for women thirty to fifty-four. All over the developing world, it’s the number one cancer-related death among young women. I think we have to again say that there is much more we could do about it than we are doing about it.”
Professor Knalul met community health workers during her work in developing countries. They were an important part of efforts to reduce deaths from the cancer. They were able to persuade people to get tested to prevent the illness. The experts say cancer care does not have to be costly. For example, patients can be treated with lower-cost drugs.
小题1:What would be the best title for the passage?

A．Cancer – a leading cause of death in poor countries

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

小题2: For a healthier life, the author’s suggestion is to ________.

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

小题3:What is the purpose of the article?

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.

It is common to have difficulties sleeping during the day. Humans are naturally wired to sleep best at night and be awake during the day. However, modern work schedules require some people to try to accommodate the unnatural schedule of shift（轮班）work — being awake at night and sleeping during the day.
In order to make this adjustment, you need to pay special attention to your sleep environment and your preparation for sleep. If shift work is a necessary part of your work life, here are some suggestions that may help.
Arrange to sleep uninterrupted in a quiet, dark room. This means you may have to turn off or unplug your phone, hang darkening curtains on the windows or wear a sleep eye mask, and train your family and friends to leave you alone while you sleep.
Fit in a nap（小睡）. When your daytime sleep period is too short, taking a short nap of less than 30 minutes just before work or on a break has been shown to improve alertness and enhance performance.
Develop and follow a sleep routine. It's best if you go to sleep and wake up at the same time every day. Try not to vary this too much on weekends. Your body likes routine.
Take extra care to make healthy choices. You may be tempted to reach for unhealthy foods or nicotine to stay awake or alcohol to try to sleep. But ultimately these choices are more harmful than helpful.
If you have tried all these things and are still having problems getting enough quality sleep during the day, talk to your doctor or a sleep specialist. Sometimes medications（药物治疗）may be helpful and safe. In other cases, there may be an underlying sleep disorder that needs to be addressed.
