Depressed people can be very difficult to be around，and yet they need more than the usual amount of support and understanding from their friends and family.
The anger and lack of concern that a depressed person may have for people close to him or her can be very disturbing to someone who's trying to help.At such times，the sincerity of a friend or a family member is questioned when the depressed person doesn't feel worthy of someone's friendship.Withdrawal from others can make it nearly impossible to encourage a depressed person to enter into activities that may help pull him or her out of the depression.
It is frequently difficult for a depressed person to carry on a conversation.Attempts to help may be met with defensiveness and verbal attacks.While being supportive and understanding，the friend of a family member must be careful not to do too many things for the depressed person.There is a very thin line between being supportive and being overly protective.Too much“doing for” can be a disservice(帮倒忙)．
You can best help a friend or relative who is depressed by considering the following points：
◆Do not moralize.Don't pressure him or her to “put on a happy face，” or to “snap out of it.” Often the person will feel even worse after hearing such words.
◆When you are alone with your depressed friend，you might say something like，“I've noticed lately that you seem down.I care about you and would like to listen to what you're thinking about.” Then be a good listener.
◆Don't say，“I know exactly how you feel.” You probably don't.But if you've had similar experiences，sharing those may help.Say things like，“This happened to me.It might help you.” Or “I know some of what you must be feeling.”
◆Urge him or her to get professional help if necessary.Offer to accompany your friend on the first visit if it will be easier for the person.
小题1:．The above passage is mainly intended for ________.

Drink More Coffee
When was the last time you heard a doctor use the word miracle? Well, wake up and smell the coffee: “It’s amazing,” says liver specialist Sanjiv Chopra, MD, professor of medicine at Harvard Medical School. “Coffee is truly a lifesaving miracle drug.”
Though he says it’s still a “scientific mystery” how a simple cup of coffee works its wonders in the body, large epidemiological studies have repeatedly proved its astonishing benefits.
“Drink it black, or at most put a little skim milk in it” to minimize calories, Dr. Chopra recommends. He drinks at least four cups a day himself, though most people should limit themselves to two. And no, he jokes, “I’m not sponsored by Starbucks.”
Take a Walk for Your Memory
Aerobic (有氧运动的) exercise is good for your body, great for your mind, according to the latest research from brain-fitness pioneer Arthur Kramer. Every year, an area called the hippocampus, which is key to memory, shrinks by about 1 to 2 percent, increasing the risk of dementia (脑衰) as the years roll by. However, Kramer’s new investigations reveal that the hippocampi of adults who walked briskly for about 45 minutes three times a week grew by about 2 percent over the course of a year, preventing age-related shrinking.
It’s never too late to start exercising, Kramer says; volunteers in his research were between 55 and 80 years old and hadn’t exercised at all. And it doesn’t need to be backbreaking. “Anything that raises your heart rate seems to work,” he says. “Walking is fine. Just find something you like and do it.”
Early to Bed, Early to Eat
“Being a night owl might increase your waistline,” says sleep expert Michael Breus, PhD. People who stay up late and sleep late tend to eat more fast food and consume more of their calories after 8 p.m. than do normal sleepers.
“One of the easiest things that anyone on a diet can do to improve her results is go to bed and wake up at the same times every day,” Breus says. “This way, your body knows when to sleep and is much more efficient. Organize your eating, too, by trying to eat meals at the same times every day. Avoid eating after 8 p.m., and don’t miss morning meals by sleeping in.”
Use the 20-Second Rule
What’s the difference between having a goal and actually accomplishing it? Just 20 seconds, says positive-psychology specialist Shawn Achor. Researchers have learned that if we can cut 20 seconds off the startup time required for a task, we’re much more likely to follow through. So, for example, if you want to work out in the morning, place your shoes and exercise clothes next to your bed the night before. If you want to praise people more, put thank-you notes and a pen on your desk.
Imagine the Worst to Feel Better
Don’t count your blessings; subtract (扣除) them. “Consciously spend a few minutes imagining what your life would be like without the good things,” says Timothy Wilson, a psychologist at the University of Virginia. You’ll experience stronger feelings of love, gratitude, and happiness when you think about what life would be like without the people and things you love. “And they’ll seem surprising and special again,” he adds.

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.
小题1:The objects of the research are women from _____.

小题2:The common way which is more likely to be infected with the disease is _____.

53.
小题4: What can be inferred from the passage?

A．Women have a higher risk to be infected by the parasite than men.

B．The result of the research may help the scientists to find ways to stop suicide in advance.

C．The scientists will continue their research into the possible connection.

D．The risk of being infected seems to rise with the decreasing levels of the antibodies.

小题5:Which of the following statements would probably be the best title of the passage?

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

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.
小题1:Through playing hide-and-seek, children are expected to learn to ________.

A．be a team leader	B．obey the basic rules

When did you see a polar bear ? On a trip to a zoo, perhaps ? If you had attended a winter activity in New York a few years ago, you would have seen a whole polar bear club. These “Polar Bears” are people who meet frequently in the winter to swim in freezing cold water. That day, the air temperature was 3 degrees. And the water temperature was a little higher. The members of the Polar Bear Club at Coney Island, New York are usually about the age of 60. Members must satisfy two requirements. First, they must get along well with everyone else in the group; this is very important because there are so many different kinds of people in the club. Polar Bears must also agree to swim outdoors at least twice a month from November through February.
Doctors don’t agree about the medical effects of cold-water swimming. Some are worried about the dangers of a condition in which the body’s temperature drops so slow that finally the heart stops. Other doctors, however, point out that there is more danger of a heart attack during summer swimming because the difference between the air temperature and the water tempreature is much greater in summer than in winter.
The Polar Bears themselves are satisfied with the benefits of cold-water swimming. They say that their favorite form of exercise is very good for the circulatory system (循环系统) because it forces the blood to move fast to keep the body warm. Cold-water swimmers usually turn bright red after a few minutes in the water. A person who turns blue probably has a very poor circulatory system and could not try cold-water swimming.
The main benefits of cold-water swimming are probably mental. The Polar Bears love to swim all the year round; they find it fun and relaxing. As one 70-year-old woman says, “When I go into the water, I pour my troubles into the ocean and let them float away.”
小题1:Doctors _________ .

A．have different ideas about the medical effects of cold-water swimming

B．believe swimming is helpful both in summer and in winter

C．enourage people to take part in cold-water swimming

A．Polar bears are bears swimming in freezing water

B．cold-water swimming can make the body temperature dangerously high

C．you are healthy if cold-water swimming turns your skin color blue

D．cold-water swimming causes more heart attack in summer than in winter

小题3:The Polar Bears like to swim year-round, for _______ .

A．it is an easy way to keep the body warm in winter

B．they can stay young

C．they find it enjoyable and interesting

D．they might meet fewer troubles in life
