Getting rid of dirt, in the opinion of most people, is a good thing. However, the attitudes to dirt are always changing.
In the early 16th century, people thought that dirt on the skin was a means to block out disease, and 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 above was long­lived, 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 first­time 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.

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.

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-theanineB.Gamma delta T cells
C.interferonD.bacteria
小题2:Tea may help strengthen the body’s defense system because it helps ______.

B.the body to produce more gamma delta T cells
C.the body to produce more interferon
D.to mix antigens with some of the cells in the body
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 CoffeeB.Our Body Needs Tea
C.Tea Can Help Prevent CancerD.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.

Why play games? Because they are fun, and a lot more besides. Following the rules…planning your next move...acting as a team member…these are all “game” ideas that you will come across throughout your life.
Think about some of the games you played as a young child, such as rope-jumping and hide-and-seek. Such games are entertaining and fun. But perhaps more importantly, they translate life into exciting dramas that teach children some of the basic rules they will be expected to follow the rest of their lives, such as taking turns and cooperating (合作) .
Many children’s games have a practical side. Children around the world play games that prepare them for work they will do as grown-ups. For instance, some Saudi Arabian children play a game called bones. Which sharpens the hand-eye coordination(协调)needed in hunting.
Many sports encourage national or local pride. The most famous games of all, the Olympic Games, bring athletes from around the world together to take part in friendly competition. People who watch the event wave flags, knowing that a gold medal is a win for an entire country, not just the athlete who earned it. For countries experiencing natural disasters or war, an Olympic win can mean so much.
Sports are also an event that unites people. Soccer is the most popular sport in the world. People on all continents play it—some for fun and some for a living. Nicolette Iribarne, a Californian soccer player, has discovered a way to give people hope through soccer. He created a foundation(基金会) to provide poor children with not only soccer balls but also a promising future.
Next time you play your favorite game or sport, think about why you enjoy it, what skills are needed, and whether these skills will help you in other aspects of your life.

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.
As hand-held devices such as smartphones are becoming more common, users are reporting some new physical problems. Florida chiropractor Dean Fishman began noticing an increased number of patients talking about neck and shoulder pain. He discovered these symptoms were due to the overuse of hand-held devices, particularly the action of bending the neck, and then coined the term “Text Neck.” As if the painful symptoms weren’t bad enough, Fishman warns that an untreated case of Text Neck could lead to permanent spinal(脊椎) damage.
Other doctors have warned about “iPad Hand,” a condition that occurs when people use tablets like the iPad for hours at a time. Most people use their left hand to support the tablet and their right hand to tap or scroll. Doing this for long periods without changing positions can result in severe joint pain.
In order to avoid or reduce the possibility of getting Text Neck or iPad Hand, use the following basic ergonomic(人体工学的) principles:
Avoid awkward positioning. Don’t strain your neck, and stay aware of how you are positioned in relation to the device. Make sure that both your neck and shoulders are relaxed and that you aren’t leaning over for a long period of time.
Take frequent breaks when using any kind of mobile device. Many doctors recommend that users change their position every 15 minutes.
When using a tablet, use a case that can support the device on a table or your lap at a comfortable viewing angle.
Along with a case, use a separate keyboard with your tablet. This will be more comfortable since you’ll be resting both hands on the keyboard. And since you won’t be holding the tablet, you’ll be less likely to experience hand or arm pain.
小题1:What kind of product for hand-held devices does the writer discuss?
A.One for recording.B.One for charging.
C.One for telephoning.D.One for typing.
小题2:Which of the following is closest in meaning to the underlined word “coined” (Para1)?
A.cashedB.createdC.changedD.completed
小题3:Which of the following is TRUE according to the passage?
A.If you are holding an iPad for long periods, it could cause spinal damage.
B.Text Neck symptoms include long-term damage in the back.
C.You are advised to lean over in relation to the device.
D.You should rest your hands on the keyboard at times.
小题4:In which magazine would you most likely find this article?
A.Personal FinanceB.Science Fiction Monthly
C.Mind and BodyD.Smartphone World
The World Health Organization recently reported that the number of cases of tuberculosis(TB) has been abating since 2006 . Also, fewer people are dying from TB. But a study by researchers at the University of California, San Francisco, says smoking could threaten this progress.
Nearly twenty percent of all people use tobacco, and millions of non-smokers get sick from breathing the smoke. The new study predicts that smoking will produce an additional thirty-four million TB deaths by 2024.
Efforts to control the spread of TB have mainly focused on finding and treating infections. Fewer efforts have been made to understand the causes. Dr Anthony Fauci is the director of the United States National Institute of Allergy and Infectious diseases. He said, “Despite our control efforts, we still have more than a million people each year dying from TB and millions of people  getting infected; we realize it’s still a very important problem. So we have to do the practical thing and we have to do the fundamental research things at the same time. ”
Smoking does not cause TB; bacteria cause the infection. But the study says smoking affects the nervous system in a way that makes an inactive case of TB more likely to develop into an active one. Stanton Glantz is the director of the University of California’s Centre for Tobacco Control Research and Education and an author of the new study. He says it shows that TB cannot be controlled unless tobacco use is controlled.  He said, “It increases the number of people who will get TB by about seven percent.”
The study is described as the first to identify a direct link between tobacco use and rates of TB infection and death. Professor Glantz says the results should guide those creating health policies and TB control efforts. He said, “If you want to control the infectious disease of TB, you have to control the tobacco industry and the tobacco industry’s efforts to increase tobacco use, particularly in developing countries where TB is a big problem.”
小题1:What would be the beat title for this passage?
A.Scientists try to find the causes of TB deaths.
B.Study shows smoking is harmful to our health.
C.Study links smoking to millions of TB deaths.
