60 times a minute for 60 minutes is 3,600 times. What physical thing can most of us do 3,600 times in one hour? Blink? Maybe. Tap our fingers on the desk? No. Jump up and down? Certainly not! But our heart keeps beating, hour after hour. Every day, it pumps almost 2,000 gallons of blood through our blood vessels(血管). It takes you about five years to drink 2,000 gallons of water.
And, unlike your knees or your back, your heart does all this work without ever complaining（抱怨）! You never know that it’s even there. Your heart is such a reliable “silent partner” that people forget to care for it. For many, the first indication（迹象）that their heart isn’t working properly is a serious heart illness! Over 650,000 Americans die of some kind of heart disease every year. Cancer kills 560,000, stroke kills 143,000, and accidents kill 118,000 Americans annually.
Like accidental deaths, many heart disease-related deaths can be avoided if people simply follow the advice of the experts. Unfortunately, most people seem to listen to a little voice in their head that says, “It won’t happen to me. ” So these people keep on smoking and drinking. They continue to eat too much meat. And their only “exercise” is getting off the sofa to get something out of the fridge. Please follow the following steps to keep your heart healthy.

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.
小题1:According to paragraph 1, many people don"t seek care because___.
| A．they can remain unaffected for long |
| B．it is unusual to seek care |
| C．they are too poor |
| D．there are too many people suffering from the disease |
| A．have to kill female mosquitoes |
| B．have ability to defend parasites |
| C．have their red blood cells infected |
| D．have sudden fever, followed by chills |
| A．Its outbreaks in cities with large populations. |
| B．Its ability to pass on the virus frequently. |
| C．Its resistance to global warming. |
| D．Its ability to defend itself and resist new drugs. |
| A．no drugs have been found to treat the disease |
| B．the alternative treatment is not easily available to most people |
| C．malaria has developed its ability to resist parasites |
| D．nobody knows what will be the drug to treat the disease |
| A．How can we know one is suffering from malaria? |
| B．How many people are killed by malaria each year? |
| C．Why are there so many people suffering from malaria? |
| D．What has been done to keep people unaffected for long? |
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.
小题1:The kings of France and England in the 16th century closed bath houses because ________.
| A．they believed disease could be spread in public baths |
| B．they thought bath houses were too dirty to stay in |
| C．they lived healthily in a dirty environment |
| D．they considered bathing as the cause of skin disease |
| A．Approving. | B．Afraid. | C．Curious. | D．Uninterested. |
| A．By providing examples. |
| B．By making comparisons. |
| C．By following the order of importance. |
| D．By following the order of time. |
| A．To stress the role of dirt. |
| B．To introduce the history of dirt. |
| C．To present the change of views on dirt. |
| D．To call attention to the danger of dirt. |
The study, which began with a self-administered questionnaire taken between 1983 and 1989, asked more than 80,000 radiologic technologists aged 22 to 92 questions about age, height, weight and smoking behavior.
BMI (body mass index) was calculated, with a BMI of 30 to 34.9 being considered obese, and 35 and over being very obese. Smoking behavior was analyzed by looking at a person"s tobacco consumption level, number of years smoked, and current smoking status. Researchers then followed participants through December of 2002, noting the number of deaths that occurred.
The study involved researchers from the National Cancer Institute, the University of Minnesota and the American Registry of Radiolegic Technologists.
Key Findings:
20 percent of obese adults in the United States smoke.
Obese smokers face a greater risk of death from cancer and circulatory disease.
Current smoking is a greater risk factor for death by cancer than obesity is, generally speaking.
The higher a person"s pack-years (number of packs smoked per day times the number of years smoked) are, the greater the risk of death.
Men and women of all ages faced an elevated risk of death due to circulatory disease as BMI increased. And for those who were both obese and currently smoking, risk of circulatory disease increased 6 to 11 times under the age of 65, as compared to their never-smoking, normal weight counterparts.
While it"s not surprising that obesity coupled with smoking is a recipe for trouble, it is important to highlight this growing health concern in America today.
Taking Charge of Your Health
Making healthy choices can be difficult when we"re constantly exposed to products that are dangerous to our health, but it"s not impossible. With education and some motivation, we all have the ability to make lasting changes for the better. If you"re an overweight smoker worried about gaining weight due to quitting, take heart. It"s never too late to change your course and even reduce damage to some extent.
小题1:60. What is the American Journal of Preventive Medicine?
| A．An medical institute. | B．A research center. |
| C．A medical magazine | D．A TV station |
| A．Obese smokers are less likely to suffer from cancer. |
| B．Obese smokers are more likely to suffer from cancer. |
| C．Obese smokers tend to gain fewer body mass index. |
| D．Obese smokers tend to get heavier than those who never smoke. |
| A．easy and possible | B．difficult and impossible |
| C．easy ant worthwhile | D．difficult but worthwhile |
| A．To inform the readers of the findings about obese smoking. |
| B．To warn the readers of the danger of obese smoking. |
| C．To tell us what obese smoking is. |
| D．To call on the obese smokers to quit smoking. |
The finding highlights the importance of paying attention to the partners of depressed mothers, as young children themselves are vulnerable (容易受伤的) 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 (围产期的) 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.

| D．To see whether it is true that behind every depressed man there is a depressed woman. |
| A．Men in stepfamilies. |
| B．Men who were not living with their partners. |
| C．Men in traditional families. |
| D．Men in nontraditional families. |
| 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. |
Then , consider this: you might be in a state of sub - health （亚健康）.
Sub - health, also called the third state or gray state, is explained as a borderline state between health and disease.
According to the survey by the National Health Organization, Over 45 percent of sub - healthy people are middle-aged or elderly. The percentage is even higher among people who work in management positions as well as students around exam week.
Symptoms （征兆）include a shortage of energy, depression, slow reactions, insomnia （失眠）and poor memory , Other symptoms include shortness of breath, sweating and aching in the waist and legs.
The key to preventing and recovering from sub - health, according to some medical experts, is to form good living habits, ale mate work and rest, exercise regularly, and take part in open air activities.
As for meals, people are advised to eat less salt and sugar . They should also eat more fresh vegetables, fruits, fish because they are rich in nutritional elements - vitamins and trace elements - that are important to the body.
Nutrition experts point out that it is not good to eat too much at one meal because it may cause unhealthy changes in the digestive tract （消化道）. They also say that a balanced diet is very helpful in avoiding sub - health.
