Tamiflu does not kill but prevents H1N1 from further proliferation (繁衍) till the virus limits itself in about 1-2 weeks (its natural cycle)．H1N1, like other Influenza A viruses, only infects the upper respiratory tract and proliferates (only) there．The only way of entry are the nostrils(鼻孔) and mouth/ throat．In a global epidemic of this nature, it's almost impossible not coming into contact with H1N1．
Contact with H1N1 is not so much of a problem as proliferation is．
While you are still healthy and not showing any symptoms of H1N1 infection, in order to prevent proliferation, some very simple steps can be practiced:
1．Frequent hand-washing．
2．"Hands-off-the-face" approach．Resist all temptations to touch any part of face (unless you want to eat or bathe)．
3．Gargle(漱口) twice a day with warm salt water (use Listerine if you don't trust salt)．H1N1 takes 2-3 days after initial infection in the throat/ nasal cavity to proliferate and show characteristic symptoms．Simple gargling prevents proliferation．In a way, gargling with salt water has the same effect on a healthy individual that Tamiflu has on an infected one．Don't underestimate this simple, inexpensive and powerful preventative method．
4．Similar to 3 above, clean your nostrilsat least once every day with warm salt water，Which is very effective in bringing down viral population．
5．Strengthen your natural immunity with foods that are rich in Vitamin C ．If you have to supplement with Vitamin C tablets, make sure that it also has Zinc to boost absorption．
6．Drink as much of warm liquids as you can．Drinking warm liquids has the same effect as gargling, but in the reverse direction．They wash off proliferating viruses from the throat into the stomach where they cannot survive, proliferate or do any harm．
7．All these are simple ways to prevent, within means of most households, and certainly much less painful than to wait in long queues outside public hospitals．
57．What part of a person’s body do H1N1flu viruses mainly infect?
A．one’s lung            B．the upper respiratory tract
C．one’s heart            D．one’s throat and lung
58．H1N1 flu viruses go into our bodies by ________．
A．touching          B．diet      C．breathing  D．dirt
59．What does the underlined word “underestimate” mean ?
A．a(chǎn)ssign too low a value to
B．drop the cost of
C．pay more attention to
D．calculate the number of money
60．The author presents this passage by ______．
A．telling an interesting story         B．testing an idea by reasoning
C．introducing some practical methods    D．describing some activities in a natural order

57---60   BCAC  

57．B 細(xì)節(jié)理解題。由第一段的H1N1, like other Influenza A viruses, only infects the upper respiratory tract and proliferates (only) there．可知。
58．C 細(xì)節(jié)理解題。由第一段的The only way of entry are the nostrils(鼻孔) and mouth/ throat．可知，病毒進(jìn)入人體的途徑是鼻孔，嘴和咽喉。因此，是通過呼吸傳染的。
59．A 詞義猜測題。由In a way, gargling with salt water has the same effect on a healthy individual that Tamiflu has on an infected one．知，在某種程度上，用鹽水漱口對健康的人有象達(dá)菲對感染患所起到的類似的作用。因此，不要低估這個簡單，便宜又有效的預(yù)防方法。Underestimate 是一個派生詞，under- 不足，下＋estimate估計。
60．C 確定寫作手法題。通讀全文作者具體介紹了如何預(yù)防甲型H1N1流感。

Winter depression (or winter blues) is a common affliction (折磨) for those who live in our northern climate. Its clinical name is seasonal affective disorder (or SAD) and up to 5% of the population (especially in northern states) may suffer from it. Seasonal affective disorder is characterized by feelings of sadness and depression that occur in the winter months when the temperatures drop and the days grow short . The depression is often associated with excessive eating or sleeping and weight gain. Women are twice to three times more likely to suffer from the winter blues than men.
There are many effective treatments for winter depression, some of which you can do to help yourself. Increasing your daily exposure to as much natural light as possible can be helpful to many. Any time that you have the opportunity to gain access to more sunlight in the winter months, you should try to do so. Taking walks throughout the day (even if you don’t normally do so), sitting next to a south-facing window at your office, in a classroom, or at home will increase your sunlight exposure. Exercising next to a window or outdoors (when possible) is another activity that can help.
Although it may be difficult to do, maintaining your schedule and lifestyle will help to keep the depression at bay. A regular pattern of sleep is the most important thing to maintain. It may be helpful, for instance, to have your bedroom lights on a timer to turn on a half-hour before you wake. This may help in waking at a regular time every morning, when it is still dark outside in the winter months.
Light therapy has shown to be an effective treatment for seasonal affective disorder. While you can purchase expensive, specialized light therapy lighting fixtures for your home or office, some inexpensive alternatives are also available. Another lighting technique to try is to replace commonly used light bulbs in your home with brighter full spectrum (also known as broad spectrum) light bulbs. While more expensive than regular light bulbs, these bulbs provide light that is similar to natural sunlight.
If none of these techniques seem to help your depressive symptoms, you should consider consulting your family physician or a mental health professional. The winter blues are a form of depression and can be readily treated w ith medications or psychotherapy when other self-help methods aren’t effective. Don’t be afraid to talk about this condition with a professional; it’s nothing to be ashamed or afraid of. With a little effort, the winter blues can be beaten

I came to live here where I am now between Wounded Knee Greek and Grass Greek。Others came too, and we made these little grey houses of logs that you see, and they are square. It is a bad way to live, for there can be no power in a square.
You have noticed that everything an Indian does is in a circle, and that is because the Power of the World always works in circles, and everything tries to be round. In the old days when we were strong and happy people, all our power came to us from the respectful circle of the nation, and so long as the circle was unbroken, the people were getting rich. The flowering tree was the living center of the circle, and the circle of the four quarters nursed it. The east gave peace and light, the south gave warmth, the west gave rain, and the north with its cold and strong wind gave strength and continuous power.
This knowledge came to us from the outer world with our brief. Everything the Power of the World does is done in a circle. The sky is round, and I have heard that the earth is round like a ball, and so are all the stars. Birds make their nests in circle, for theirs are the same as ours. The sun comes forth and goes down again in a circle. The moon does the same, and both are round. Even the seasons form a great circle in their changing, and always come back again to where they were. The life of a man is a circle from childhood to childhood, and so it is in everything where power moves.
Our places were like the nests of birds, and these were always set in a circle, the nation’s circle, a nest of many nests, where the Great Spirit meant for us to nurse our children.
But the “white people” have put us in these square boxes. Our power is gone and we are dying, for the power is not in us any more. You can look at our boys and see how it is with us. Where we were living by the power of the circle in the way we should, boys were men at twelve or thirteen years of age. But now it takes them very much longer to grow up.
小題1:According to the passage, the Indians _______.
A．don’t have modern instruments in their homes
B．refused to move from round places
C．lived in round places, but were forced to live in square houses
D．lived in round places, but then decided to move into square houses
小題2:Two things being compared in the passage are _______.
A．the Indians’ past and present living conditions
B．the Indians’ past and modern beliefs
C．the Indians’ old and new power
D．people and nature
小題3:In the second paragraph “the four quarters” refers to _______.
A．the four rooms of the Indian’s house
B．the four kinds of natural power
C．the four seasons
D．the four directions
小題4:According to the author, once the Indians moved into square houses, _______.
A．they had to move to other houses
B．boys took more time to grow into men
C．they forgot the old way of life
D．everyone was not happy

People express their personalities in their clothes, their cars, and their homes. Our diets can also show our personalities because we might choose certain food to tell people something about us.
For example, some people mainly enjoy high quality food, such as caviar (魚子醬) and lobster (龍蝦), and they eat only in expensive restaurants – never in cafeterias or bars. They know about the “better things in life”.
Some people choose not to eat meat. Vegetarians often have more in common than just their diet. Their personalities might be similar too. For instance, vegetarians in the United States and Canada may be creative people, and they might not enjoy competitive sports or jobs. They worry about the health of the world, and they are probably strongly against the war.
Some people eat mostly fast food. One study shows that many fast-food eaters have a lot in common, but they are very different from vegetarians. They are competitive and good at business. They are also usually in a hurry. Many fast-food eaters might not agree with this description of their personalities, but it is a common picture of them.
Some people also believe that people of the same astrological sign（星座）have similar food personalities. Aries (born under the sign of Aries, between March 21 and April 20) usually like spicy foods, with a lot of onions and pepper. People with the sign of Taurus (April 21 to May 22) prefer healthful fruits and vegetables, but they often eat too much. Sagittarius (November 22 to December.22) like traditional food from many different countries.
What is your food personality?
小題1:Why do some people mainly eat high quality food?
A．They want to show off their wealth.B．Food can show off their social position.
C．They want to enjoy better things in life.D．They are wiser than any other persons.

A study published Monday found that people who sleep less tend to be fat, and experts said it’s time to find out if more sleep will fight fatness.
“We’ve put so much emphasis on diet and exercise that we've failed to recognize the value of good sleep,” said Fred Turek, a physician at Northwestern University.
Monday’s study from Eastern Virginia Medical School in Norfolk covered 1,000 people and found that total sleep time decreased as body mass index - a measure of weight based on height - increased.
Men slept an average of 27 minutes less than women and overweight and fat patients slept less than patients with normal weights, it said. In general the fatter subjects slept about 1.8 hours a week less than those with normal weights.
“Americans experience insufficient sleep and fat bodies. Clinicians are aware of the burden of fatness on patients,” the study said.
“Our findings suggest that major extensions of sleep time may not be necessary, as an extra 20 minutes of sleep per night seems to be associated with a lower body mass index,” it added.
“We caution that this study does not establish a cause-and-effect relationship between restricted sleep and fatness (but) investigations indicating success in weight loss via extensions of sleep would help greatly to set up such a relationship.”
The study was published in the Archives of Internal Medicine along with an editorial by Turek and Northwestern colleague Joseph Bass commenting on it and related research.
In an interview, Turek said some studies have shown sleep causes declines in an appetite suppressing protein hormone, and increases in another hormone that causes a longing for food. In addition neuropathies（神經(jīng)療法）in the brain governing sleep and fatness appear to overlap（重疊）, he said.
Patness has been rising dramatically in developed countries and reached epidemic（流行�。� levels in the United States, it added, leading to a variety of health problems.
66. What’s the passage mainly about?
A. People who sleep less tend to get fat.
B. Fat people need lots of sleep to lose weight.
C. Sleeping has nothing to do with fatness.
D. Fatness has been rising dramatically in developed countries.
67. According to the passage, which of the following is TRUE?
A. Lack of sleep causes declines in a desire limiting protein hormone.
B. Americans experience sufficient sleep and fat bodies.
C. The findings suggest that major extensions of sleep time may be necessary.
D. Fatness has been rising dramatically in America.
68. Which of the following is NOT close to the underlined word suppress?
A. limit          B. restrict       C. accept         D. control
69. According to the passage, which of the following people is the lowest possible one to get fatness?
A. Americans      B. Chinese        C. Japanese       D. English

B
There is an English saying: “l(fā)aughter is best medicine.” Until recently, few people took the saying seriously. Now however, doctors have begun to look into laughter and the effects it has on the human body. They have found that laughter really can improve people’s health.
Tests were carried out to study the effects of laughter on the body. People watched funny films while doctors checked their hearts, blood pressure, breathing and muscles. It was found that laughter had similar effects to physical exercise. It increases blood pressure, the heart beating and breathing; it also works several groups of muscles in the face, the stomach, and even the feet. If laughter exercises the body, it must be beneficial.
Other tests have shown that laughter appears to be able to reduce the effect of pain on the body. In one experiment doctors produced pain in groups of students who listened to different radio programmer. The group that tolerated the pain for the longest time was the groups which listened to a funny programmer. The reason why laughter can reduce pain seems to be that it helps to produce a kind of chemicals in the brain which diminish both stress and pain.  
As a result of these discoveries, some doctors in the United States now hold laughter clinics, in which they help to improve their patients’ condition by encouraging them to laugh. They have found that even if their patients do not really feel like laughing, making them smile is enough to produce beneficial effects similar to those caused by laughter.
60.Doctors have proved the following EXCEPT that      .
A. smiling does good to health                  B. laughter can be tolerated
C. there is a way to reduce pain                      D. laughter can work the muscles in the feet
61. The main idea of the passage is       .
A. laughter and physical exercise have similar effects on the human body
B. smile can produce the same effects as laughter
C. pain can be reduced by laughter  
D. laughter is the best medicine
62.The underlined word “diminish” is similar to       .
A. test             B. stop                     C. reduce                  D. increase
63. Doctors hold laughter clinics _________.
A. to give better condition to their patients
B. in order to improve patients’ health
C. to make patients smile   
D. to prove smile and laughter have the same effect
