Malaria, the world's most widespread parasitic(寄生蟲引起的) disease, kills as many as three million people every year—almost all of whom are under five, very poor, and African. In most years, more than five hundred million cases of illness result from the disease, although exact numbers are difficult to assess because many people don't (or can't) seek care. It is not unusual for a family earning less than two hundred dollars a year to spend a quarter of its income on malaria treatment, and what they often get no longer works. In countries like Tanzania, Mozambique, and the Gambia, no family, village, hospital, or workplace can remain unaffected for long.
Malaria starts suddenly, with violent chills, which are soon followed by an intense fever and, often, headaches. As the parasites multiply, they take over the entire body. Malaria parasites live by eating the red blood cells they infect. They can also attach themselves to blood vessels in the brain. If it doesn't kill you, malaria can happen again and again for years. The disease passed on to humans by female mosquitoes infected with one of four species of parasite. Together, the mosquito and the parasite are the most deadly couple in the history of the earth—and one of the most successful. Malaria has five thousand genes, and its ability to change rapidly to defend itself and resist new drugs has made it nearly impossible to control. Studies show that mosquitoes are passing on the virus more frequently, and there are more outbreaks in cities with large populations. Some of the disease's spread is due to global warming.
For decades, the first-choice treatment for malaria parasites in Africa has been chloroquine, a chemical which is very cheap and easy to make. Unfortunately, in most parts of the world, malaria parasites have become resistant to it. Successful alternatives that help prevent resistance are already available, but they have been in short supply and are very expensive. If these drugs should fail, nobody knows what would come next.

A new study has found evidence of aggressive (攻擊性的) behavior in children who drink four or more servings of soft drinks every day. Information for the study came from the mothers of 3,000 5-year-olds. Researchers asked the women to keep a record of how many servings of soft drinks their children drank over a two-month period. They were also asked to complete a checklist of their children’s behavior.
The researchers have found that 43 percent of the children drink at least one daily serving of soda, and 4 percent of the youngsters have even four or more sodas to drink every day.
Shakira Suglia, a famous expert, says they’ve found that children who drink the most soda are more than twice as likely as those who drink no soda to show signs of aggression.
“For the children who consume four or more soft drinks per day, we see more withdrawn behaviors, which make them hard to get along well with others.”
The aggressive behaviors include destroying possessions belonging to others, taking part in fights and physically attacking people.
The researchers have determined the link after considering factors like the child’s age and sex. They have also considered other possible influence, such as whether the boys and girls are eating sweets or giving fruit drinks on a normal day. In addition, the researchers have examined parenting styles and other social conditions that may be taking place in the home.
Researches are trying to find why young children who drink a lot of soda have behavior problems. An ingredient often found in soft drinks is caffeine, which helps to make people feel energetic. Doctor Suglia suggests that caffeine could cause the 5-year-olds to be more aggressive. Earlier studies of adults have found the highest sugar levels in those who carry weapons (武器) and show signs of negative social behavior.
【小題1】What section of a newspaper is the passage probably taken from?

A.Scientific TechnologyB.Science Fictions
C.Social NewsD.Health Report
【小題2】The underlined word “withdrawn” in paragraph 4 can probably be replaced by the word ______.
A.backwardB.unsocialC.generousD.friendly
【小題3】Researchers studied the following aspects of the children except ______.
A.a(chǎn)geB.sexC.gamesD.parents
【小題4】According to the research, which of the following is right?
A.Mothers were asked to keep a record of how many servings of soft drinks their children drank over a three-month period.
B.4 percent of the youngsters have even four or fewer sodas to drink every day.
C.Children who drink no soda show fewer aggressive behaviors.
D.Children with the highest sugar levels tend to carry weapons and show signs of negative social behavior.
【小題5】After a further study on ingredients in soda, Shakira Suglia implies that the direct cause of the aggressive behaviors may be ______.

While there has been public debate about whether running is good for your health for a long time, experts agree that running has more benefits than the costs. Some people are concerned that the pressure on your knees and ankles can be detrimental. While this can be true, there are many things that you can do to reduce your risk of injury.
You should always go to a doctor for advice before you begin any type of exercise program. Then, a good pair of running shoes can be helpful as your feet hit the ground. They will help protect your ankles by providing stability to your feet. So it is good idea to visit a specialty(專業(yè)) running shoe store. The staff there can suggest shoes which are ideal for your running style.

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 (肺結(jié)核) and malaria (瘧疾) 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.
【小題1】What would be the best title for the passage?

A.Cancer – a leading cause of death in poor countries
B.What should we do in preventing and treating cancer?
C.What makes the first killer in developing countries?
D.Experts urge more efforts to fight cancer.
【小題2】Felicia Knaul’s experience in Mexico shows that       .
A.many Mexican women suffer from breast cancer
B.there is not enough medicine for cancer there
C.many Mexican women can’t afford medical care
D.patients with breast cancer are treated differently
【小題3】From what Felicia Knaul says, we can draw the conclusion that       .
A.breast cancer is a great threat to young women
B.people don’t pay enough attention to breast cancer
C.breast cancer is the second killer among women in Mexico
D.patients can be treated effectively in developing countries
【小題4】Who plays an important part in preventing the cancer in developing countries?
A.The cancer patients. B.The health experts.
C.Community health workers.D.Young women.
【小題5】Which of the following is TRUE according to the passage?

Forgiving someone who has hurt you or let you down is never an easy thing. Several new studies, however, say that it could have a lot of health benefits. When you think of forgiveness, you probably don’t think of it as being a health or medical problem. Studies from Stanford University, on the other hand, show that something like anger can change your well-being.
When cartoon book characters like the Incredible Hulk get angry, they change colours and often gain special power. In the real world, anger is less obvious and may be more dangerous. That’s why Professor Fred Luskin, founder of the Stanford Forgiveness Project and author of Forgive for Good, says holding on to anger and hatred can harm your physical and mental health. Two new studies seem to show the same idea.
The studies find that people who are able to forgive feel less stress, less back pain, and less depression(抑郁). They also have fewer headaches, lower blood pressure, and fewer problems on sleeping.
So it doesn’t matter if your anger is caused by the traffic or other things. Learning to let it go is important. Techniques such as deep breath or thought can help. Or just ask yourself if it’s worth hurting yourself by staying angry with someone else.
Forgiveness does not mean that you simply accept what happened and say it’s OK. Instead, it’s a way of making peace with yourself about what happened in the past.
【小題1】The author of the passage tries to make his viewpoint clear__________.

A.by raising his own examples
B.based on his own experience
C.by mentioning some studies
D.by mentioning some typical patients
【小題2】The example of the cartoon book characters is taken in the passage to__________.
A.support the viewpoint that anger and hatred harm physical and mental health
B.introduce a famous expert
C.let the reader know the different colours of cartoon faces
D.show how to control one’s temper
【小題3】 The underlined phrase“holding on to”in this passage possibly means“__________”.
A.removing B.keeping up C.getting rid of D.learning about
【小題4】Which of the following is NOT mentioned in this passage?
A.People who are able to forgive feel less stress.
B.People who are able to forgive feel less depression.
C.People who are able to forgive have fewer problems on sleeping.
D.People who are able to forgive feel less tired.

You may have heard about the many benefits of yoga, but a recent New York Times story, has stirred up more than a little controversy in the yoga community.
"How Yoga Can Wreck Your Body," by science writer William J. Broad, quotes a long-time yoga teacher who "...has come to believe that 'the vast majority of people' should give up yoga altogether. It's simply too likely to cause harm." He goes on to describe a number of cases where people have been injured doing yoga, including himself.
The research in the article isn't groundbreaking: doing any form of exercise you could potentially hurt yourself. If you look at the injury rates of other physical activities, the number of injuries sustained from yoga would pale in comparison.
Practicing yoga is just like anything in life: You have to push yourself in order to grow. But you also have to know your limits and when you're breaking them. If you stick to your comfort zone, you'll never be able to increase your flexibility. If you push to the point where you're not only uncomfortable, but in real pain, you'll likely injure yourself.
The reasons that yoga causes "serious injury”, according to the Times story, range from students' physical weaknesses to inexperienced teachers pushing too hard to the growing number of inflexible "urbanites who sit in chairs all day" trying hard to twist themselves into difficult postures.
Yoga is called a "practice" for a reason. You don't have to be perfect. You don't have to tackle every pose. It doesn't matter if you can touch the floor with your palms during your first forward bend or your thousandth, or if you never get there.
We go to the mat to learn to better listen to what our bodies are telling us, and to better hear that quiet inner voice drowned out by the noise of our busy lives. It's a shame to discourage the majority of people from practicing yoga and missing out on all of the mind-body benefits that going to the mat has to offer.
【小題1】The underlined word is best replaced by __.

A.Injure B.Benefit C.Push D.Shape
【小題2】What does author mainly want to tell us in the 3rd paragraph?
A.All physical activities are equally harmful.
B.Yoga causes much less injuries than other physical activities.
C.Similar researches have been done before.
D.Yoga, like any other form of exercise, can hurt people.
【小題3】Which is not mentioned among the reasons for yoga being likely to cause injury?
A.Teachers lack the knowledge of students’ limits.
B.Modern lifestyle decreases our flexibility.
C.The body doesn’t tell when you are in real pain.
D.Students themselves might not be in good physical condition.
【小題4】What is the author’s attitude towards practicing yoga?
A.It’s a shame not to practice yoga.
B.One should push the limits in order to be perfect.
C.The majority should give up yoga for it may cause harm.
D.One should enjoy the physical and mental benefit that yoga brings.

FDA proposed the most sweeping food safety rules in decades, requiring farmers and food companies to be more cautious in the wake of deadly outbreaks in peanuts, cantaloupe (瓜),and leafy greens.
The long-overdue regulations are aimed at reducing the estimated 3,000 deaths a year from foodbome illness. Just since last summer, outbreaks of listeria (李氏桿菌)in cheese and salmonella(沙門氏菌)in peanut butter, cantaloupe and mangoes have been linked to more than 400 illnesses and as many as seven deaths, according to the Centers for Disease Control. The actual number of those sickened is likely much higher.
The FDA’s proposed rules would require farmers to take new precautions against contamination (污染),to include making sure workers5 hands are washed, irrigation (灌溉) water is clean, and that animals stay out of fields. Food manufacturers will have to submit food safety plans to the government to show they are keeping their operations clean.
Many responsible food companies and farmers are already following the steps that the FDA would now require them to take. But officials say the requirements could have saved lives and prevented illnesses in some of the large-scale outbreaks that have hit the country in recent years.
In a 2011 outbreak of listeria in cantaloupe that claimed 33 lives ,for example, FDA inspectors found pools of dirty water on the floor and old, dirty processing equipment at the Colorado farm where the cantaloupes were grown. In a peanut butter outbreak this year linked to 42 salmonella illnesses ,inspectors found samples of salmonella throughout a New Mexico peanut processing plant and multiple obvious safety problems ,such as birds flying over uncovered trucks of peanuts and employees not washing their hands.
Under the new rules, companies would have to lay out plans for preventing those sorts of problems and how they would correct them.
“The rules go very directly to preventing the types of outbreaks we have seen/,said Michael Taylor, FDA’s deputy commissioner for foods.
【小題1】The main task of FDA is probably______

A.to protect and promote the public health
B.to help those sickened recover
C.to research on food safety measures
D.to deal with water pollution
【小題2】According to the passage, the new rules focus on_____.
A.inspecting the whole process of food production
B.improving food processing equipment on farms
C.preventing water pollution in food production
D.urging food companies to lay out plans
【小題3】What does the word “they” in Paragraph 3 refer to?
A.Inspectors.B.Farmers
C.Manufacturers.D.Workers.
【小題4】Which of the following is TRUE according to the passage?
A.The new regulations should have come into practice earlier.
B.The 2011 outbreak of listeria is the most serious ever.
C.Farmers and food companies are strongly against the new rules.
D.Colorado and New Mexico are worst hit by food pollution.
