Feel tired lately?Has a doctor said he can’t find anything wrong with you?Perhaps he sends you to a hospital,but all the advanced equipment there shows there is nothing wrong with you.
Then,consider this:you might be in a state of sub-health(亞健康).
Sub-health,also called the third state or gray state,is explained as borderline state between health and disease.
According to the investigation by the National Organization,over 45 percent of sub-health 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 lack of energy,depression,slow reactions,insomnia(失眠),agitation, 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, alternate 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(微量元素)—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.

A punctual person is in the habit of doing a thing at the proper time and is never late in keeping an appointment.
The unpunctual man, on one hand, never does what he has to do at the proper time. He is always in a hurry and in the end loses both time and his good name. A lost thing may be found again, but lost time can never be regained. Time is more valuable than material things. In fact, time is life itself. The unpunctual man is for ever wasting and mismanaging his most valuable asset (財(cái)產(chǎn)) as well as other’s. The unpunctual person is always complaining that he finds no time to answer letters, or return calls or keep appointments promptly. But the man who really has a great deal to do is very careful of his time and seldom complains of want of it. He knows that he can not get through his huge amount of work unless he faithfully keeps every piece of work when it has to be attended to.
Failure to be punctual in keeping one’s appointments is the sign of disrespect towards others. If a person is invited to dinner and arrives later than the appointed time, he keeps all the other guests waiting for him. Usually this will be regarded as a great disrespect to the host and all other guests present.
Unpunctuality, moreover, is very harmful when it comes to do one’s duty, whether public or private. Imagine how it would be if those who are put in charge of important tasks failed to be at their proper place at the appointed time. A man who is known to be habitually unpunctual is never trusted by his friends or fellow men.
小題1:What does the author think is the main difference between a punctual person and an unpunctual person?
A．A punctual person does everything ahead of time while an unpunctual person does everything behind schedule.
B．A punctual person does everything at the right time while an unpunctual person seldom does anything at the correct time.
C．A punctual person has a lot of appointments while an unpunctual person has few appointments.
D．A punctual person has much time to do everything while an unpunctual person has little time to do anything.
小題2: According to the passage, the main reason that a person is always unpunctual is that _______.
A．he has more work to do than other people
B．he is always in a hurry when he works
C．he doesn’t care much about time
D．he always mismanages and wastes his time
小題3:According to the third paragraph, when you are invited to dinner, you should arrive there _______.
A．a(chǎn)fter other guests have arrived
B．before all other guests
C．a(chǎn)t the appointed time
D．a(chǎn)fter the host has got things ready
小題4:Which of the following statements best describes the harm of unpunctuality?
A．If you are an unpunctual person, you cannot be in charge of any important task.
B．If your friends know that you are unpunctual, they may not see you again.
C．Unpunctuality may bring about heavy losses for both public and private affairs.
D．Unpunctuality may make you miss a lot of appointments and lose friends.

Saturday, October 7th, was a marathon of sad tasks for Anna Politkovskaya. Two weeks earlier, her father, a retired official in the department of foreign affairs, had died of a heart attack as he emerged from the Moscow Metro while on his way to visit Politkovskaya’s mother, Raisa Mazepa, in the hospital. She had just been diagnosed(診斷) with cancer and was too weak even to attend her husband’s funeral. “Your father will forgive me, because he knows that I have always loved him,” she told Anna and her sister, Elena Kudimova, the day he was buried. A week later, she had an operation and since then Anna and Elena had been taking turns helping her deal with her grief.
Politkovskaya was supposed to spend the day at the hospital, but her twenty-six-year-old daughter, who was pregnant, had just moved into Politkovskaya’s apartment, on Lesnaya Street, while her own place was being prepared for the baby. “Anna had so much on her mind,” Elena Kudimova told me when we met in London, before Christmas. “And she was trying to finish her article.” Politkovskaya was a special reporter for the small newspaper Novaya Gazeta, and, like most of her work, the piece focused on the terror that can be seen all over the southern republic of Chechnya. This time, she had been trying to report repeated cruel acts done by people faithful to the Prime Minister, Ramzan Kadyrov, who are in favour of Russia. In the past seven years, Politkovskaya had written dozens of accounts of life during wartime; many had been collected in her book “A Small Corner of Hell: reports from Chechnya.” Politkovskaya was far more likely to spend time in a hospital than on a battlefield, and her writing bore frequent witness to robbery, and the uncontrolled cruelty of life in a place that few other Russians—and almost no other reporters—cared to think about.
41. Politkovskaya’s father died of ______.
A. tiredness          B. a heart disease        C. an attack       D. an accident
42. From the text we know that Raisa Mazepa ______.
A. didn’t love her husband                   
B. didn’t attend her husband’s funeral
C. was having an operation the day her husband was buried
D. was too sad to attend her husband’s funeral
43. The underlined word “emerged” most likely means ______.
A. came out        B. went into      C. disappeared      D. left for
44. How many family members of Anna are mentioned in the passage?
A. Three.           B. Four         C. Five            D. Six
45. Which of the following words can best describe Politkovskaya’s character?
A. Curious         B. easy-going     C. careless          D. responsible

Doctors say obesity，also known as severe overweight，is a complex condition.A doctor may advise medical interventions(醫(yī)療干預(yù)) in addition to changes in behavior.But experts say the more successful weight­loss plans include a well­balanced diet and exercise.
People who want to avoid weight gain have to balance the number of calories they eat with the number of calories they use.To lose weight，you can reduce the number of calories you take in，or increase the number you use，or both.Experts at the National Institutes of Health say to lose weight，a person should do some moderate or intensive physical exercise most days of the week.This could include fast walking，sports or strength training.
A recent study looked at four of the most popular dieting plans in the United States.Researchers at Stanford University studied more than three hundred overweight women，mostly in their thirties or forties.Each woman went on one of the four plans：Atkins，The Zone，Ornish or LEARN.The women attended diet classes and received written information about the food plans.At the end of a year，the women on the Atkins diet had lost the most，more than four and a half kilograms on average.
Christopher Gardner led the study，reported in the Journal of the American Medical Association. He said the Atkins diet may be more successful because of its simple message to lower the intake of sugar.Also，he said the advice to increase protein in the diet leads to more satisfying meals.
But last week，another report suggested that only a small minority of people have long­term success in dieting.Researchers at the University of California found that most dieters regained their lost weight within five years.And often they gained back even more.But those who kept the weight off generally were the ones who exercised.

What do former American president Bill Clinton and rock musician Pete Townshend have in common.'? Both men have hearing damage from exposure(暴露，接觸) to loud music, and both now wear hearing aids（助聽器） as a result. As a teenager, Clinton played saxophone in a band. Townshend, who has the more severe hearing loss, was a guitarist for a band called the Who. He is one of the first rock musicians to call the public's attention to the problem of hearing loss from exposure to loud music.
Temporary（暫時(shí)） hearing loss can happen after only 15 minutes of listening to loud music. One early warning sign is when your ears begin to feel warm while you listen to music at a rock concert or through headphones. One later is that an unusual sound or a ringing is sometimes produced in your head after the concert.
"What happens is that the hair cells in the inner ear are damaged, but they're not dead," says physician and ear specialist Dr. Sam Levine. According to Dr. Levine, if you avoid further exposure to loud noise, it's possible to recondition the cells（細(xì)胞） somewhat. However, he adds, "Eventually, over a long period of time, hair cells are permanently damaged." And this is no small problem.
What sound level is dangerous? According to Dr. Levine, regular exposure to noise above 85 decibels (分貝) is considered dangerous. The chart below offers a comparison of decibel levels to certain sounds. Here's another measurement you can use. If you're at a rock concert and the music is so loud that you have to shout to make yourself heard, you' re at risk for hearing loss. That's when wearing protective devices such as earplugs becomes critical.
The facts are pretty frightening. But are rock bands turning down the volume.'? Most aren't. "Rock music is supposed to be loud," says drummer Andrew Sather."I wouldn't have it any other way. And neither would the real fans of rock. "
Continued exposure to loud music and the failure to wear earplugs can lead to deafness, according to Dr. Levine. He states, "There's no cure for hearing loss. Your ears are trying to tell you something. That ringing is the scream of your hair cells dying. Each time that happens, more and more damage is done. "
Levels of Common Noises
Normal conversation                            50 — 65 dB
Food blender                                  88 dB
Jet plane flying above a person standing outside      103 dB
Rock band during a concert                      110 — 140 dB
小題1:From Paragraph 1, we can learn that ___________                  .
A．loud music is a major cause of hearing loss
B．famous people may have hearing problems
C．teenagers should stay away from school bands
D．the problem of hearing damage is widely known
小題2:In Paragraph 3, the underlined word "recondition" means__________ .
A．not to be seenB．to fill with sound
C．to become larger in sizeD．to make good again
小題3:The purpose of the chart at the end of the article is to show__________   .
A．a(chǎn) list of harmful sounds
B．the effect of rock concerts
C．the noise levels of sounds
D．relationship between daily activities and hearing loss
小題4:Which of the following statements will Dr. Sam Levine probably agree?
A．When your ears feel warm, your hair cells are dead.
B．Drummer Andrew Sather gives good advice.
C．Many are at the risk of losing hearing.
D．Doctors know how to deal with hearing loss.

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

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

American children are not the only couch potatoes with nearly one third of children globally spending 3 hours a day or more watching TV or on computers, according to the study of over 70,000 teens in 34 nations.
From Argentina to Zambia, Regina Guthold of the World Health Organization in Geneva and her colleagues found most children were not getting enough exercise and that it made no difference whether they live in a rich or a poor country. “With regards to physical levels, we didn’t find much of a difference between rich and poor countries,” Guthold said, “Growing up in a poor country doesn’t necessarily mean kids get more physical activities.”
The researchers defined adequate physical activity as at least an hour of exercise outdoors for at least 5 days a week. Children spending 3 or more hours a day watching TV, playing computer games or chatting with friends were classified as sedentary.
The researchers found only a quarter of the boys and 15 percent of the girls were getting enough exercise by these definitions. A quarter of boys and nearly 30% of girls were sedentary and didn’t get enough exercise with girls less active than boys in every country aside from Zambia.
Girls from India were the most active with 37 percent meeting exercise recommendation, while girls from Egypt were the least active with 4 percent getting enough exercise. Children in Myanmar were the least sedentary while the most sedentary nations were St .Lucia and the Cayman Islands.
People show deep concern for kids’ lack of physical activity in various nations. Why do they have a low level of physical activity? Guthold speculated（認(rèn)為）that urbanization could be a factor as well as easy access to cars and TVs.
小題1:If you are sedentary, you ____________.   
A．a(chǎn)re a diligent student spending much time doing homework
B．have at least an hour of exercise outdoors 5 days a week.
C．like watching TV and playing computer games

A．Children in poor countries get more physical activities.
B．Girls in Egypt are more active than those in India.
C．Couch potatoes are those children addicted to snacks.
D．Children in Myanmar are less sedentary than those in St .Lucia.

Christian Eijkman, a Dutch doctor, left the Netherlands for the island of Java. Many people on the island had a disease called beri-beri. He was going there to try and find a cure.
At first, Eijkman thought some kind of germ (細(xì)菌) caused beri-beri. He raised some chickens. He didn’t eat them, but made experiments on them. The local people were quite surprised at that. One day he noticed that his chickens became sick when they were fed the food most Javanese ate — refined white rice (精煉米). When he fed them with unrefined rice, also known as brown rice, they recovered. Eijkman realized that he had made an important discovery — that some things in food could prevent disease. These things were named vitamins (維生素). The Javanese were not getting enough vitamins because they had actually removed the part that contains vitamins. Later, other diseases were also found to be caused by the lack of vitamins in a person’s food.
Today many people know the importance of vitamins and they make sure they have enough vitamins from the food they eat. If they don’t, they can also take vitamin pills.
小題1:The underlined word “cure” in Paragraph 1 probably means ______.
A．a(chǎn) medical treatment B．a(chǎn) kind of vitaminC．a(chǎn) kind of germD．a(chǎn) kind of rice

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.
