Have you ever been bitten? Of course you have. You are surrounded by living things which might, or do, bite. Even when you rest your head on your pillow, bedbugs are probably nibbling away(蠶食) at you. They live happily inside most pillows.
Take a walk outside and you are a target for “man’s best friend. ” Hundreds of dog-bite victims visit US emergency rooms daily. Many bites are terrible. To avoid the dogs in your neighborhood, you might want to hike into the desert or the woods. There, you run the risk of bites from rattlesnakes, scorpions, and blood-sucking ticks. Not to mention bears, wolves, coyotes, and mountain lions.
Speaking of housing, watch out when you touch the corner of your house or garage. Shy but deadly, the black widow spider and the brown recluse spider make themselves comfortable in quiet areas of your closets or garage. One bite from either of them can make you very sick; occasionally, people die from such bites. Unfortunately, many people fear all spiders, not just the few dangerous ones. They squash them or run from them at first sight, not realizing that most spiders are actually beneficial to man.
If you’re concerned about bites, don’t forget about rabid(患有狂犬病的) animal bites. Any warm-blooded animal can get infected with rabies. Although humans in the US rarely get attacked by rabid animals, the disease is painful and dangerous. You will most likely die if you are not treated properly within 48 hours of being bitten.

The World Health Organization and several other United Nations agencies are calling for a major new effort to fight malaria, tuberculosis and AIDS. These three infectious diseases killed almost 6 million people last year. That is about 10 percent of the total number of deaths around the world last year.
The WHO and UN agencies released a new report at the World Economic Forum in New York City earlier this month. The document says that deaths around the world from malaria and tuberculosis could be cut in half by the year 2010. It also says the number of deaths from AIDS could be reduced 25 percent within that same time period.
The report is called “Calling Up the Response to Infectious Diseases.” It calls for huge new investments in methods to prevent and treat infectious diseases. Officials say money is needed for research and to purchase drugs. Money is also needed to devices to prevent diseases, such as bed nets. Bed nets prevent mosquitoes that carry malaria from biting people while they sleep.
David Heymann, director of the infectious disease program at the World Health Organization, says that providing effective drug treatments is important for improving peoples’ health and economic well – being. Reducing disease can also help improve economic growth in developing countries.
The WHO report also describes successful health programs in developing countries. In Peru, for example, the number of tuberculosis cases was cut in half by increasing the treatment to control the disease. In Vietnam, malaria was reduced 97 percent through the use of bed nets. And in Uganda, cases of the virus that causes AIDS were cut in half among pregnant women and children through the use of anti – AIDS drugs.
This new international health campaign is estimated to cost about 12,000 million dollars a year. So far, officials say the campaign has about 2,000 million dollars. The WHO says the campaign will need stronger relationships among government, private aid agencies, and drug companies to succeed.
小題1:According to the report         is the disease most difficult to fight.
A.malariaB.tuberculosisC.AIDSD.influenza
小題2:To prevent these diseases, a large amount of money is needed to          .
A.to buy food and pay for the caretakers
B.do research work, buy drugs and devices
C.take care of the families of the deaths
D.set up more hospitals and health institutions
小題3:We can infer from the text that reducing infectious diseases is          .
A.to help the countries develop better
B.to promote cooperation between countries
C.to help people get more scientific knowledge
D.to help people get a cleaner environment
小題4:Most serious infectious diseases spread mainly in         .
A.AfricaB.South America

Work your brain!
Between 2 and 3 pounds of wonder, it controls everything we say, do or think, who we are and what we care about. The way we walk or laugh or figure out things. What we like and the talents we possess. How we see and talk and run and jump and process our food.
The brain uses 20 percent of our body’s oxygen and 20 percent of its blood. Somewhere within its protein, fat, 100,000 miles of blood vessels and 100 billion nerve cells, it helps us remember where we put our gym shoes. Change our temperature so we don’t die because of the heat or cold. Speed us up or slow us down. Help us choose between orange juice or orange­flavored drinks.
Its complexity are stunning, far beyond anything most of us can imagine. To keep this work of art as polished as possible we need to eat right, exercise and keep mentally stimulated. Good nutrition helps brain cells communicate with each other. Exercise stimulates a hormone in our brain that improves memory. Mental stimulation keeps you sharp even as you age.
“It’s very important that we tell people to be physically active and mentally active,” said neurologist Malcolm Stewart.“People cannot stop aging, but you’re able to reduce the damage; you’re able to keep the function up.”
Following are Dr. Stewart’s advice for improving brain health:
Nutrition
Avoid fast food. Follow the old adage(格言): For breakfast, eat like a king; for lunch, like a queen; for supper, like a beggar.
Exercise
Do a combination of stretching aerobic and muscle strengthening every day.
Mental games
Try to have a sense of hope about the future. Do puzzles. Listen to music. Reach out to others to make their lives better.
小題1:The purpose of the author in writing this passage is to ______.
A.inform us how the brain works
B.give us advice on how to keep the brain healthy
C.tell us that the brain plays an important role in our lives
D.show how special the brain is to us

About a third of all common cancers in the United States, China and Britain could be prevented each year if people ate healthier food, drank less alcohol and exercised more, health experts said on Friday.
Reports from the World Cancer Research Fund (WCRF) suggest that making simple lifestyle changes could prevent some 40 percent of breast cancers alone in Britain and the United States, as well as tens of thousands of stomach cancers.
“Even in 2011, people are dying unnecessarily from cancers that could be prevented through keeping a healthy weight, diet, physical activity and other lifestyle factors,” said a WCRF medical and scientific adviser.
WCRF findings are supported by World Health Organization (WHO) reports, which say regular exercise can prevent many diseases such as cancers and heart diseases.
Cancer is a leading cause of death around the world and its incidence(發(fā)病率) is rising. Each year around 12.7 million people discover they have cancer and 7.6 million people die from some form of the disease. There are about 200 known types of cancer.
Rachel Thompson, the WCRF’s head of science, said that while the message was simple — that not smoking, eating good food and being a healthy weight can help ward off many cancers — it was still a difficult one to get across.
The WHO says adults should do at least 150 minutes of exercise a week. This could be done by walking for 30 minutes five times per week or by cycling to work every day.
Peter Baldini, head of the World Lung Foundation, also called on all governments to introduce smoke-free laws and raise the price of cigarettes. Tobacco kills millions of smokers every year, and tobacco-related lung cancers also kill hundreds of thousands of people who don’t smoke but have been exposed to it second-hand.
“There isn’t a magic bullet to cure all forms of cancer, but we have the opportunity and the duty to protect people from developing cancer wherever possible,” Baldini said.
小題1:Which of the following words can best take the place of the phrase “ward off” in the sixth paragraph?
A.protectB.preventC.developD.cure。
小題2:Which of the following statements is Not true according to the text?
A.Exercising and eating healthily can help to reduce cancer risk.
B.Each year about 12.7 million people are diagnosed with cancer around the world.
C.Every year millions of people die from smoking and lung cancers.
D.Adults should walk for fifty minutes three times per week.
小題3:Which of the following can be the best title of this text?
A.Simple life changes could stop millions of cancers
B.Cancer is a leading cause of death
C.Our bad lifestyle caused many diseases
D.The incidence of common cancers is rising
小題4:By writing the passage, the author mainly intends to ____.
A.a(chǎn)dvise people to develop healthier lifestyle.
B.warn people of the danger of cancers
C.explain why many people die from cancers every year.
D.introduce the ways to protect people from developing cancers
小題5:We can infer from Peter Baldini’s opinion in the last two paragraphs that ____.
A.a(chǎn)ll the lung cancers are linked to smoking
B.there is no medicine to cure the cancers but it’s our duty to find one
C.a(chǎn)ll governments should take measures to control smokers and protect people’s health
D.it’s our opportunity and duty to persuade people to give up smoking

Researchers in London and Bristol have found that men are particularly likely to yield to depression if their partners are also depressed.
The finding highlights the importance of paying attention to the partners of depressed mothers, as young children themselves are vulnerable (容易受傷的) to social problems if both parents are depressed.
Researchers in London and at the University of Bristol launched their study to investigate whether family structure affects the likelihood of depression in men around the time their child is born. They looked at men from traditional families, men with children from a previous relationship, men whose partners had children by a former partner, and men who were not living with their partners.
All 7,108 participants filled out a questionnaire on depression, and answered questions about their age, education level and employment status. Details about the quality of their relationships with their partners, networks of friends and previous life events were also recorded.
About 3.5 percent of the men and 13 percent of their partners suffered depression around the time their child was born. While men in stepfamilies or who were not living with their partners were twice as likely to get depressed as those in traditional families, this could be explained by other factors that are more common in nontraditional families, such as poor education and relationship conflicts.
Even allowing for all these factors, however, the partners of women who were suffering from prenatal (圍產(chǎn)期的) depression were significantly more likely to become depressed themselves, the researchers report in an American journal. Ten percent of women who were depressed had depressed partners. For the healthy women, the figure was only 2.6 percent.
Previous research suggests that families with two depressed parents may need special attention. A researcher in Atlanta has found that primary school children with two troubled parents have difficulty relating to their peers. “It’s extremely important to look at the whole family.” she says.
小題1:What can we conclude from the first two paragraphs of this passage?
A.Men often beat their children.
B.Depressed women often have depressed partners.
C.All young children are vulnerable to social problems.
D.Women with children often have depressed partners.
小題2:Why did researchers in London and Bristol carry out such an investigation?
A.To see what kind of family environment is ideal for children to grow up in.
B.To study whether family structure affects depression in men when their child is born.
C.To investigate why so many men get depressed when a child is born.
D.To see whether it is true that behind every depressed man there is a depressed woman.
小題3:What kind of men is least likely to get depressed when their child was born?
A.Men in stepfamilies.
B.Men who were not living with their partners.
C.Men in traditional families.
D.Men in nontraditional families.
小題4:According to the passage, which of the following statements is NOT true?
A.Ten percent of women who were depressed had depressed partners.
B.2.6 percent of healthy women were depressed.
C.Special attention should be paid to families in which both the father and the mother were depressed.
D.Primary school children whose parents were both depressed couldn’t get along well withtheir peers.

According to the survey conducted by some scientists, it is common to have difficulty 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(輪班)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 (藥物治療) may be helpful and safe. In other cases, there may be an underlying sleep disorder that needs to be addressed.
小題1:The purpose of the text is to_____ .
A.persuade workers to have a good sleep
B.a(chǎn)dvise night workers to keep healthy
C.encourage workers to do day work

小題3:On which condition should a person turn to a sleep specialist for help?
A.If he suffers from a sleep disorder for the first time.
B.If a good sleep environment is greatly needed for him.
C.If he fails to get quality sleep through his own efforts.
D.If he has the problem of falling asleep in the daytime.
小題4:We can learn from the text that_____________.
A.night workers need a long time to fall asleep

Why are people interested in eating raw foods or whole foods (天然健康食品) ? One reason is that eating these types of food reduces the risk of acid (酸) accumulation in your body.
Raw and whole foods are usually digested more efficiently than cooked foods. When we cook foods, we destroy the natural enzymes (酶) that are part of the food in its raw form. These enzymes were intended by nature to help us digest the food. When we consume food without these natural enzymes, our bodies either digest the food improperly or allow too many nutrients to be absorbed into the bloodstream. In both instances, the result is overweight. When too many nutrients are absorbed at once, the body grows fat. Improperly digested food moves slowly through the digestive system, where it becomes increasingly acidic. To protect its vital organs from this acidic waste, the body changes the acid into fat and stores it safely away from the organs.
Processed foods (加工食品) contain chemical elements, which might confuse the appetite mechanism that tells us when we’ve had enough to eat; as a result, people often overeat. Processed foods also upset the digestive cycle. The body will either identify these foods as allergens and then store them safely away from the organs as fat, or the remains of undigested food will become acidic and enter the bloodstream as acid waste, which will stick to the blood vessel walls and block the passage of vital oxygen and nutrients heading for the body’s cells. The body’s metabolism (新陳代謝) becomes inactive, and the result is weight gain and obesity.
The accumulation of acid in the digestive system makes digestion increasingly inefficient. When that happens, even healthy foods can become acidic and the food allergies will become more common.
To stop this vicious circle in its tracks, people need to consume food and supplements that will neutralize the acid already accumulated in body. Eating the right types of raw and whole foods can help. It’s also important to restore your enzyme balance. You need to identify and avoid the foods that cause acid accumulation and consume the foods that increase enzyme production. If you truly want to change and help your body heal itself, you need to take an active approach. One effective way is to choose raw and whole foods appropriately according to your health conditions and personal preferences.
小題1:It can be inferred from Para. 2 that __________.
A.we’d better be cautious about raw and whole foods
B.foods with natural enzymes help people keep fit
C.it is important for people to protect their vital organs
D.giving up cooked and refined foods is a new lifestyle
小題2:Processed foods are unhealthy because they __________.
A.destroy body’s cellsB.harm your stomach

Was the London Olympics a success? Many people hold different opinions. However one thing is certain, London could win a gold medal for hosting the “greenest” Games ever, BBC News reported.
Previous Olympic hosts have been criticized for the environmental damage they have caused through construction, waste. and transport. But things had to be different in London because seven years ago it bid for the Olympics through the concept of “a One Planet Olympics”.
What is most impressive is that London used the construction of the Olympic Park as an opportunity to clean up polluted areas — 2 million tons of contaminated (被污染的) soil were removed and 200 old factory buildings, were torn down, according to sustainablebusiness.com. But that’s not all —. 99 percent of the debris (廢瓦礫) were reused to build the Olympic Park. For example, part of the Olympic Stadium’s roof is made from 2,500 tons of steel tubes recycled from old gas pipelines.
As well as using recycled materials, all venues were built with green building techniques. The Olympic Stadium is the lightest one ever built, which minimized the amount of steel and concrete needed. Also, the handball field has lighting pipes on the roof that reduce electricity use by 40 percent, according to sustainablebusiness.com.
The effort that London made to deal with waste also deserves praise. Water used for drinking and watering plants was from collected rainwater or recycled wastewater. In this way. about 30-40 percent less water was used in total. Waste food packages were either recycled or processed and turned into renewable energy.
As one of the best connected places in Europe, London tried to solve traffic jams by encouraging the use of public transport. For example, it had trains deliver half of the building materials, instead of cars, which greatly reduced carbon emissions.
The clean anti-doping (反興奮劑) result also added to the greenness of the Games. The International Olympics Committee (IOC) said that the devices used this time were the most accurate and advanced. Only one athlete tested positive for a banned drug on the day of competing, which is why the IOC President, Jacques Rogge, has praised anti-doping efforts at the London Games.
小題1:To make the Olympic Park green, London _______.
A.recycled 2 million tons of contaminated soil
B.removed 99 percent of the debris from the city
C.built the Olympic Stadium mostly with recycled materials
D.a(chǎn)pplied green building techniques to the construction work
小題2:The underlined word “minimized” in the fourth paragraph probably means
A.increased as much as possible
B.reduced as much as possible
C.made good use of
D.took little notice
小題3:What can we conclude from the article?
A.The London Olympics cost less than the other Olympics ever held.
B.London has possessed the most advanced techniques to deal with waste.
C.Public transport is made good use of in London during the Olympic games.
D.The anti-doping result in the London Olympics turned out to be dissatisfactory.
小題4:Which of the following best shows the structure of the text?

A friend of mine was in low spirits one day. He usually dealt with this state of mind by avoiding people until the mood passed. But on that day Fred had an important meeting with his boss, so he decided to put on a false front. During the meeting Fred smiled, joked and played the part of a happy, good-natured person. To his surprise, he soon discovered he was no longer depressed. 
Without realizing it, Fred chanced to find an important new principle of psychological research: acting a part can help us feel the way we want to feel — more self-assured in a trying situation, more cheerful when things go wrong.
How can you put this principle to work in your own life? There’s more involved than simply mimicking a few expressions. You have to be systematic about it. Here’s how:
Smile to cheer yourself up.
Relax to reduce anxiety or fear.
Look your best to increase your self-confidence.
Keep cool in a crisis.
Using our bodies and actions to change the way we feel can be a useful tool in helping us through life’s difficult times. As novelist George Eliot wrote more than a century ago, “Our deeds determine us, as much as we determine our deeds.” People who remember that — and act upon it — can only be richer and happier for the experience.
小題1:In paragraph 1 the underlined phrase “to put on a false front” means ______.
A.to wear a wrong coat
B.to act a part unsuccessfully
C.to show a pretended happy appearance
D.to put on airs
小題2:According to Paragraph 1, Fred ______before the meeting.
A.had very few spirits
B.had many spirits
C.was in bad mood
D.was in good mood
小題3:The underlined phrase mimicking in Paragraph 3 most probably means ______.
A.learning quickly
B.making faces
C.behaving well
D.imitating others
小題4:In the last paragraph, the quotation “Our deeds determine us, as much as we determine our deeds” may show that ______.
A.a(chǎn)ctions speak louder than words
B.the more we do, the happier we are
C.our feeling cannot change our behavior
D.a(chǎn)ctions are very important for us to beat bad moods for good
