Autumn and winter are cold and flu seasons. Will the old advice about dressing warmly help prevent a cold, or if you get sick, should you follow the old saying, “feed a cold and starve a fever?” And what about that fever? Should you take medicine to reduce your temperature, or is it better to let the body treat the fever itself? Everyone seems to have an answer. But is popular wisdom valuable?
Doctor Nelson knows a lot about cold and flu seasons. Nelson says research may be just starting to provide proofs for long-held beliefs. For example, scientists for years were against the idea that getting cold and wet might cause colds or flu. But recent studies have shown that cold temperatures cause stress on the body, and that stress can create conditions more inviting to viruses. So maybe it does make sense to wrap up warmly before going outside.
And what about feeding a cold and starving a fever? Nelson says if you have a cold and are hungry, you should eat. But a fever, especially a high one, suggests a more serious problem. He says people are usually not hungry when they have a high fever. Eating might even make a person sick. But drinking enough water is important. A fever easily makes the body lose water.
Finally, when should you treat a fever? Nelson says a fever should be treated if it stays at
40℃ or above for a day or more. A high temperature can damage brain cells. The doctor also believes in treating a fever if it prevents a person from sleeping.
Medicine like aspirin, for example, can be used to reduce pain and fever. But aspirin should not be given to children because it can cause serious problems.
小题1:We can learn from the passage that Doctor Nelson________.
A.doesn’t believe in the old advice about preventing colds
B.is now trying his best to provide proofs for long-held beliefs.
C.doesn’t think it necessary to see a doctor immediately if a person has a temperature of 40℃
D.doesn’t think it necessary to treat a fever even if it prevents someone from sleeping.
小题2:According to Doctor Nelson, if someone catches a fever, he should________.
A.bathe in cold waterB.drink enough water
C.try to eat somethingD.take some exercise outside
小题3:Which of the following is Not mentioned in the passage?
A.When people should treat a fever
B.Whether the old advice about preventing a cold is valuable.
C.What the medicine , aspirin, is used for.
D.Why people should eat when having a cold.
小题4:The passage suggests that_______.
A.aspirin can damage train cells if an adult takes too much of it.
B.it is easier for people to catch colds when their bodies are stressed.
C.some old advice about preventing colds doesn’t make any sense.
D.the idea that getting cold can cause flu was proved true years ago.

小题1:C
小题2:B
小题3:D
小题4:B

小题1:推理题:从文章第四段的句子Nelson says a fever should be treated if it stays at 40℃ or above for a day or more. 说明如果发高烧达到40度以上长达一天多,就要治疗了,也就是如果刚刚发烧达40度,就没必要治疗。选C。
小题2:细节题:从文章第三段的But drinking enough water is important. 可知喝水很重要。选B。
小题3:排除题:A项是出现在第四段。同第一题的解析,文章的第二段Nelson says research may be just starting to provide proofs for long-held beliefs. 说明B项正确,文章最后一段的Medicine like aspirin, for example, can be used to reduce pain and fever.说明C项正确,就是没提到D。
小题4:细节题:从文章的最后一段的:But recent studies have shown that cold temperatures cause stress on the body, and that stress can create conditions more inviting to viruses.说明身体有压力的时候很容易生病。选B。

Have you ever walked outside thinking it was one temperature but quickly discovered it felt colder? That is because of the “wind chill” effect.
Wind chill is how cold people and animals feel when they are outside, not the actual temperature on the thermometer(温度计). It is based on how quickly your body loses heat when it is exposed to wind and cold. When the wind is strong, your body quickly loses heat, making the temperature of your skin drop.
When scientists first started calculating wind chill, they used research conducted in 1945 by explorers to Antarctica who measured how quickly water froze outside.
But water freezes faster than exposed skin, so the wind chill index based on that data wasn’t accurate.
In 2001, the US government began to measure wind chill more precisely by testing how quickly people’s skin froze.
Twelve volunteers were placed in a chilled wind tunnel. Equipment was stuck to their faces to measure the heat flow from their cheeks, forehead, nose and chin while they walked three miles per hour on a treadmill(跑步机).
The experiment revealed how quickly exposed skin can be damaged, particularly unprotected areas like your fingers, toes, the tip of your nose and your ear lobes. In fact, 40 percent of your body heat can be lost through your head! Signs you might have frostbite(冻疮) are when the skin turns white or pale and you lose feeling in that area.
The information collected from the volunteers helped scientists work out the math to compute wind chill. It involves wind speed and air temperature.
If, for example, the temperature outside is zero degrees Fahrenheit and the wind is blowing at 15 miles per hour, the wind chill is calculated at 19 degrees below zero. At that wind chill temperature, exposed skin can freeze in 30 minutes.
You can find a calculation table at www.nws.noaa.gov/om/windchill/index.shtml.
Experts advise in cold weather that you wear loose-fitting, lightweight, warm clothing, worn on top of each other. Air caught between the clothes will keep you warm. The best cold-weather coats have head coverings made of woven material that keep out water. So next time the temperature drops and you want to play outside, listen to your parents when they tell you to wrap up warm!
小题1: According to the text, wind chill _______.
A.means how fast exposed skin freezes
B.doesn’t affect your head as much as other body parts
C.changes according to the temperature on the thermometer
D.changes from person to person depending on their health
小题2: When might a person have frostbite according to the passage?
A.When his skin turns red and he loses feeling in that area.
B.When he is running faster and he is losing strength quickly.
C.When his face is exposed and quickly loses heat even indoors.
D.When his skin turns pale and he has no feeling in that area.
小题3: What factors influence wind chill?
A.A person’s body temperature and will speed.
B.Wind speed and a person’s strength.
C.Air temperature and wind speed.
D.The location and air temperature.
小题4: What can we conclude from the passage?
A.It was in 1945 that scientists first began to calculate wind chill.
B.Compared with water, people’s exposed skin freezes more slowly.
C.The wind chill index based on Antarctica data is considered a standard.
D.With the development of technology, many previous researches have been proven wrong.

“Everybody loves a bargain.” One person’s useless, ugly, or broken object can be another person’s bargain. That is why so many Americans do not throw things away. They put them outside their houses. They put on a “For Sale” sign. And, as simple as that, they have a yard sale.        
The sellers put a paid announcement(付费通告)in a local newspaper. It tells when and where the yard sale will take place. These sales are very popular during weekends in spring, summer, and autumn. Early in the morning, all the things to be sold are carried out of the house. Then they sit all day in the sunlight---like tired guests at a party---waiting for someone to take them home.
Just about anything can be sold at a yard sale. Sometimes, there are more clothes than anything else. Cooking equipment is also popular. So are old toys, tools, books, tables and chairs. Then there are objects called “white elephants”. A white elephant is something you think is extremely ugly or useless. It may be an electric light shaped like a fish. You feel a sharp pain whenever you look at it. To someone else, however, it might be a thing of beauty and joy.
Some people go to yard sales to find a special thing that they collect. It may be old toy trains, for example, or painting of dogs. Experts say more Americans are collecting old things now than ever before. Most people who go to yard sales, however, are not looking for anything special. They might buy an object simply because it costs so little. They enjoy negotiating(谈判) over prices, even if they really do not need the object. Later, they may hold their own yard to sell all the things they have bought.
小题1:What kind of things will go to a yard sale?
A.Cheap and ugly things.B.Things people no longer use.
C.Things out of season.D.Things of great value.
小题2:A white elephant refers to _________.
A.something that can cause a feeling of pain
B.something disliked by the owners while appreciated by others
C.something sold at the lowest prices
D.a toy shaped like a fish
小题3: Most people go to yard sales to________.
A.find valuable paintingsB.look for something special
C.find a bargainD.kill their time
小题4: Which of the following is NOT true about a yard sale?
A.It may not be held when the weather is very cold.
B.It can last for a whole day.
C.It is usually held with a party.
D.It is held outdoors.
小题5:We can infer from the last paragraph that__________.
A.people may find something of great value on a yard sale
B.yard sales only attract those who have a low income
C.things on a yard sale can cost people a lot
D.most people don’t want to go to yard sales.

Life in 2060
Let us suppose it is now about A.D. 2060. Let’s make believe(假设;虚构) it is about sixty years from now. Of course, things have changed and life is very different.
Voyages to the moon are being made every day. It is as easy to take a holiday on the moon today as it was for the people in 1960 to take a holiday in Europe. At a number of scenic spots on the moon, many hotels have been built. The hotels are air-conditioned, naturally. In order that everyone can enjoy the beautiful scenery on the moon, every room has at least one picture window. Everything imaginable is provided for entertainment(娱乐) of young and old.
What are people eating now? People are still eating food. They haven’t yet started to take on heir(继承) supply of energy directly as electrical current or as nuclear power. They may some day. But many foods now come in pill form, and the food that goes into the pill continues to come mainly from green plants.
Since there are several times as many people in the world today as there were a hundred years ago, most of our planet’s surface has to be filled. The deserts are irrigated with water and crops are no longer destroyed by pests. The harvest is always good.
Farming, of course, is very highly developed. Very few people have to work on the farm. It is possible to run the farm by just pushing a few buttons now and then.
People are now largely vegetarians(素食者). You see, as the number of people increases, the number of animals decreases. Therefore, the people have to be vegetarians and we are healthier both in our bodies and in our minds, and we know the causes and cure of disease and pain, and it is possible to get rid of diseases. No one has to be ill any more.
Such would be our life in 2060.
小题1:According to the passage, what will be on the moon in about A.D. 2060?
A. Many tourists.   B. Many other animals.   C. Many plants.     D. A sea.
小题2:What will people eat then according to the passage?
A.Biscuits in pill form.B.Foods in gas form.
C.Foods in water form.D.Foods in pill form.
小题3:Why are people largely vegetarians in 2060?
A.Because they don’t eat meat .
B.Because doctors advise them not to eat meat.
C.Because the number of animals decreases.
D.Because all the animals have died of diseases.

Open Letter to an Editor
I had an interesting conversation with a reporter recently --- one who works for you. In fact, he’s one of your best reporters. He wants to leave.
Your reporter gave me a copy of his resume(简历) and photocopies of six stories that he wrote for you. The headlines showed you played them proudly. With great enthusiasm, he talked about how he finds issues(问题), approaches them, and writes about them, which tells me he is one of your best. I’m sure you would hate to lose him. Surprisingly, your reporter is not unhappy. In fact, he told me he really likes his job. He has a great assignment (分工), and said you run a great paper. It would be easy for you to keep him, he said. He knows that the paper values him. He appreciates the responsibility you’ve given him, takes ownership of his profession, and enjoys his freedom.
So why is he looking for a way out?
He talked to me because he wants his editors to demand so much more of him. He wants to be pushed, challenged, coached to new heights.
The reporter believes that good stories spring from good questions, but his editors usually ask how long the story will be, when it will be in, where it can play, and what the budget is.
He longs for conversations with an editor who will help him turn his good ideas into great ones. He wants someone to get excited about what he’s doing and to help him turn his story idea upside down and inside out, exploring the best ways to report it. He wants to be more valuable for your paper. That’s what you want for him, too, isn’t it?
So your reporter has set me thinking.
Our best hope in keeping our best reporters, copy editors, photographers, artists --- everyone --- is to work harder to make sure they get the help they are demanding to reach their potential. If we can’t do it, they’ll find someone who can.
小题1:What does the writer think of the reporter?
A.Optimistic. B.Imaginative. C.Ambitious.D.Proud.
小题2:What does the reporter want most from his editors in their talks?
A.Finding the news value of his stories. B.Giving him financial support.
C.Helping him to find issues.D.Improving his good ideas.
小题3:Who probably wrote the letter?
A.An editor.B.An artist. C.A reporter. D.A reader.
小题4:The letter aims to remind editors that they should ______.
A.keep their best reporters at all costs
B.give more freedom to their reporters
C.be aware of their reporters’ professional development
D.appreciate their reporters’ working styles and attitudes

阅读下面短文,从每题所给的A、B、C和D项中,选出最佳选项,并在答题卡上将该项涂黑。Roy wasn't the only one to receive his call-up(入伍)papers.Stephen Napier's call-up came at the beginning of February and he was pleased to find that he would be going into the Royal Air Force (RAF).
His father was not so pleased and made his feelings known as he and Stephen were on their daily walk. It was the first step in his plans for Stephen to take over the estate(地产)when the time came, and although Stephen was well aware of this, he could think of no reason not to accompany him.
"Thought you'd forgotten that nonsense. Still, I dare say I could pull a few strings to get you to the Army..."
"No, Father! I have told you I want to learn to fly. What chance would I have to do that in the Army? I'd be better off in the Navy——at least they've got the Fleet Air Arm. But I have been put in the RAF and that's where I want to be, so let's leave it at that." His face went red. Sent to his father's school and then to Cambridge, much to his satisfaction, he had never had to defend his own desires and his father was a hard man to oppose.
The father glared at Stephen, "No, I won't leave it at that. I want to know what other ridiculous ideas are in your head. For a start, what's all this about America?"
"America?"
"Yes. All those books I saw in your room the other day. Brochures about emigration(移民)."
The big, silvered head lowered, like that of a bull about to charge."Don't trouble to deny it."
"I won't, Father. Some men at Cambridge have been talking about it. They want people like us here, mathematicians and scientists, for all kinds of research——the sort of research I could do.It would be a worthwhile life for me."
The father responded exactly as his son had known he would."You've got a worthwhile life here!You've got an estate to run!"
"No, Father. You've got an estate to run. I never asked for it. Why not ask Baden to do this stuff? He perhaps can make a good job of it, but I..."
"If he were here, I might think about this silly idea of yours——only think about it, mind you but..."
小题1:If Father wanted Stephen to take over the estate, the first thing he did would__________.
A.take a walk with Stephen as usual
B.wait till his son graduated from Cambridge
C.persuade Stephen not to go into RAF
D.send Stephen to the Army instead of RAF
小题2:Which statement is NOT true according to the passage?
A.Stephen preferred to go into the Navy rather than the Army.
B.Stephen also received his call-up papers as Roy.
C.The father didn't like Stephen's idea of going to America.
D.Stephen was eventually forced to stay to run the estate.
小题3: After reading this passage, we can infer that__________.
A.Stephen had never had to defend his desires before
B.Baden might be one of Stephen's family members
C.Stephen wanted to fly in RAF and become a pilot in America
D.if somebody took over the estate, Stephen could realize his dream
小题4:What do we learn from the underlined sentence?
A.It looked as if the father was angry when mentioning the brochures.
B.The father was very angry and wanted to beat his son Stephen.
C.Stephen was annoyed when his father referred to the brochures.
D.A big red bull was about to charge at Stephen.
小题5:Which would be the best title for this passage?
A.RAF——a better choice than the Army B.A talk between Father and Son
C.The dreams of a Cambridge student D.Conflict between Father and Son
