The common cold is the world's most widespread illness, which is plagues(疫病) that flesh receives.
The most widespread mistake of all is that colds are caused by cold. They are not. They are caused by viruses(病毒) passing on from person to person. You catch a cold by coming into contact, directly or indirectly, with someone who already has one. If cold causes colds, it would be reasonable to expect the Eskimos to suffer from them forever. But they do not. And in isolated Arctic regions explorers have reported being free from colds until coming into contact again with infected people from the outside world by way of packages and mail dropped from airplanes.?
During the First World War soldiers who spent long periods in the trenches(戰(zhàn)壕), cold and wet, showed no increased tendency to catch colds.?
In the Second World War prisoners at the notorious Auschwitz concentration camp(奧斯維辛集中營), naked and starving, were astonished to find that they seldom had colds.?
At the Common Cold Research Unit in England, volunteers took part in Experiments in which they gave themselves to the discomforts of being cold and wet for long stretches of time. After taking hot baths, they put on bathing suits, allowed themselves to be with cold water, and then stood about dripping wet in drafty room. Some wore wet socks all day while others exercised in the rain until close to exhaustion. Not one of the volunteers came down with a cold unless a cold virus was actually dropped in his nose.?
If, then, cold and wet have nothing to do with catching colds, why are they more frequent in the winter? Despite the most pains—taking research, no one has yet found the answer. One explanation offered by scientists is that people tend to stay together indoors more in cold weather than at other times, and this makes it easier for cold viruses to be passed on.?
No one has yet found a cure for the cold. There are drugs and pain suppressors(止痛片) such as aspirin, but all they do is to relieve the symptoms(癥狀).?
小題1:The writer offered _______ examples to support his argument.?
A.4B.5 C.6D.3
小題2:Which of the following does not agree with the chosen passage??
A.The Eskimos do not suffer from colds all the time.?
B.Colds are not caused by cold.?
C.People suffer from colds just because they like to stay indoors.?
D.A person may catch a cold by touching someone who already had one.
小題3:Arctic explorers may catch colds when ________.
A.they are working in the isolated Arctic regions?
B.they are writing reports in terribly cold weather?
C.they are free from work in the isolated Arctic regions?
D.they are coming into touch again with the outside world

"When their kids are   9 the house, they might smoke. Or they smoke in the car. Or they strap(用帶子捆扎) the kid in the car seat in the back and crack the window and   10 , and they think it's okay because the second-hand smoke isn't getting to their  11 .

But   17 fewer of those surveyed were aware of the  18 of third-hand smoke. Since the term is so new, the researchers asked people if they agreed with the statement that "breathing air in a room   19 where people smoked yesterday can harm the health of infants and children"。
Only 65 percent of nonsmokers and 43 percent of smokers agreed with that  20 , which researchers interpreted as acknowledgement of the risks of third-hand smoke。

Fat and shy,Ben Saunders was the last kid in his class picked for any sports team. “Football,tennis,cricket—anything with a round ball,I was useless,” he says now with a laugh. But back then he was the one always made fun of in school gym classes in Devonshire,England.
It was a mountain bike he received for his 15th birthday that changed him. At first he went biking alone in a nearby forest. Then he began to ride the bike along with a runner friend. Gradually,Saunders set up his mind on building up his body,increasing his speed and strength. At the age of 18,he ran his first marathon.
The following year he met John Ridgway and was hired as an instructor at Ridgway’s school of adventure in Scotland,where he learnt about Ridgway’s cold-water exploits. Greatly interested,Saunders read all he could about North Pole explorers and adventures,then decided that this would be his future.
  In 2001,after becoming a skillful skier,Saunders started his first long-distance expedition towards the North Pole. It took unbelievable energy. He suffered frostbite,ran into a polar bear and pushed his body to the limit,pulling his supply-loaded sled up and over rocky rice.
  Saunders has since become the youngest person to ski alone to the North Pole,and he’s skied more of the North Pole by himself than any other British man. His old playmates would not believe the change.
Next October,Saunders,27,heads south from the coast of Antarctica to the South Pole and back,a 2900-kilometer journey that has never been completed on skis.

Vitamin E supplements(補充品),which millions take in the hope of longer, healthier lives, may do more harm than good, researchers reported on Wednesday.?
In fact, people taking high doses(劑量)of vitamin E may in some cases be more likely to die earlier, although the reasons are not clear, said Dr. Edgar Miller of Johns Hopkins University in Baltimore, who led the study.“I think people take vitamin E because they think it is going to make you live longer, but this(study)doesn’t support that.”Miller told reporters.?
Miller and colleagues re?analyzed 19 studies of vitamin E and health between 1993 and 2004. The tests involved more than 136,000 mostly elderly patients in North America, Europe and China. People who took 200 international units of vitamin E a day or more died at a higher rate during the study, which lasted three years, than people who did not take supplements, they told a meeting of the American Heart Association.“It’s about a 5 percent increased risk at 45 years in the tests combined together,”Miller said.“That doesn’t sound like a lot but if you apply it to 25 percent of the (U.S.)adult population taking vitamin E, that is significant.”?
Miller, whose findings are also being published online by the Annals of Internal Medicine, said two?thirds of people who take vitamin E supplements take 400 IU or more.“We don’t think that people need to take vitamin E supplements, which they can get enough from the diet,”he said. Nuts, oils, whole grains and green leafy vegetables are all rich in vitamin E.?
小題1: People take vitamin E supplements, hoping that________.?
A.they can lose weight easily?

  Centuries ago, man discovered that removing moisture from food helps to store it, and that the easiest way to do this is to expose the food to sun and wind.
All foods including water — cabbage and other leaf vegetables contains as much as 93% water, potatoes and other root vegetables 80%, lean (瘦的) meat 75% and fish, anything from 80% to 60%, depending on how fatty it is. If this water is removed, the activity of the bacteria which cause food to go bad is controlled.
Nowadays most foods are dried mechanically. The conventional method of such dehydration (脫水) is to put food in chambers (室) through which hot air is blown at temperature of about ll0'C at entry to about 43'C at exit. This is the usual method for drying such things as vegetables, minced meat, and fish.
Liquids such as milk, coffee, tea, soups and eggs may be dried by pouring them over a heated steel cylinder (圓筒), then put them into a chamber through which a current of hot air passes. In the first process, the dried material comes off the roller (滾筒) as a thin film which is then broken up into small, though still relatively flakes (薄片). In the second process it falls to the bottom of the chamber as small powder. Where recognizable pieces of meat and vegetables are required, as in soup, the ingredients (成分) are dried separately and then mixed.
Dried foods take up less room and weigh less than the same food packed in cans or
frozen, and they do not need to be stored in special conditions. For these reasons they
are invaluable to the climbers, explorers and soldiers in battle, who have little storage
space. They are also popular with housewives because it takes so little time to cook
them.
小題1:It can be inferred from the passage that ________.
A.the rattier fish contain as much water as the lean one
B.the rattier the fish is, the more water it may contain
C.a(chǎn) fatty fish holds less water than a lean one
D.the water content of fish has nothing to do with the content of their fat
小題2: The underlined word "conventional" in Paragraph 3 can most probably be replaced by _________.
A.particularB.scientificC.usualD.special
小題3:Which of the following statements is NOT true about drying food?
A.The removal of water in food helps prevent it from going rotten.
B.The open-air method of drying food has been known for hundreds of years.
C.In the course of dehydration, the temperature of hot current coming from entry to exit is gradually going up.
D.The process of drying liquids is much more complex than that of drying solid food.
小題4:The last paragraph mainly talks about __________.
A.the reason why housewives like dried food
B.the general convenience of dried food
C.the methods of storing food
D.the advantages of dried, canned and frozen food

Are you sometimes a little tired and sleepy in the early afternoon? Many people feel this way after lunch. They may think that eating lunch is the cause of the sleepiness. Or, in summer, they may think it is the heat. However, the real reason lies inside their bodies. At that time – about eight hours after you wake up – your body temperature goes down. This is what makes you slow down and feel sleepy. Scientists have tested sleep habits in experiments where there was no night or day. The people in these experiments almost always followed a similar sleeping pattern. They slept for one long period and then for one short period about eight hours later.
In many parts of the world, people take naps(小睡) in the middle of the day. This is especially true in warmer climates(氣候), where the heat makes work difficult in the early afternoon. Researchers are now saying that naps are good for everyone in any climate. A daily nap gives one a more rested body and mind and therefore is good for health in general. In countries where naps are traditional (傳統(tǒng)的), people often suffer less from problem such as heart disease.
Many working people, unfortunately, have no time to take naps. Though doctors may advise taking naps, employers do not allow it! If you do have the chance, however, here are a few tips about making the most of your nap. Remember that the best time to take a nap is about eight hours after you get up. A short sleep too late in the day may only make you feel more tired and sleepy afterward. This can slao happen if you sleep for too long. If you do not have enough time, try a short nap – even ten minutes of sleep can be helpful.

Remember how great exercise was when you were a little kid? Back then, racing around the playground or skipping rope for hours, you weren’t thinking fitness, you were thinking entertainment. But in this age of high-tech home equipment and underused gym memberships, the simple joy of jumping rope has been forgotten, Rediscovering it will give you a total-body exercise you can find.
Although considered an excellent form of exercise, jumping rope has never gained widespread acceptance because of two fundamental reasons. First, most people recognize jumping rope as an excellent form of cardiovascular(心血管的)exercise, but they also believe that it is simply too difficult. In other words, they don’t think they’ll be able to continue jumping for the near 20 minutes that it takes to achieve a beneficial physical outcome. Second, many view it as somewhat boring and overly repetitive not as something fun or enjoyable.
As a matter of fact, jumping rope can be great fun if you find a proper way to practice it. Instead of doing the usual two-foot bounce over and over again, people good at rope-jumping often change their pattern every 10 or 20 jumps. A single bounce, a double-bounce, a skip, a knee-up, side swings, as well as a variety of other easy-to-learn free-style rope-jumping.
Now researchers are learning that jumping rope also prepares the brain for learning. It is an exercise allowing both brain hemispheres to perform in parallel to each other. In short, jumping rope can be a life-long activity requiring little equipment, time and space, yet leading to a much healthier life.
61. From the first paragraph we learn that_________.
A. jumping rope has faded from people’s memories
B. people now have more advanced equipment
C. racing around the playground was preferred
D. people now like to have exercise in a gym
62.Rope jumping has not spread widely because_________.
A. it benefits the cardiovascular system
B. it is neither easy nor enjoyable
C. it is considered boring and repetitive
D. it requires little equipment, time and space
63.The first sentence in the 3rd paragraph implies_________.
A. there is only one proper way to follow
B. the usual way should not be used
C. the easiest way is always the best
D. there are many ways to follow
64.According to the researchers, jumping rope_________.
A. only prepares the brain for learning
B. is suitable for students only
C. helps both brain hemispheres work together
D. can be dangerous for old people
65.What is the author’s attitude towards rope jumping?
A. He is arguing against it
B. He is in favor of it
C. He is sitting on the fence of it
D. He is not clear about it

On Saturday, Feb 12, 2000, two things happened that changed my life.
First of all, my baby sister got married. She was 26 this day, and yet to me she was still my baby sister.
I was happy, but also sad. Gone were the days of me bossing(支使) her around. My bossy behavior had once earned me the nickname Lucy. If you’re a fan of Peanuts, then you can clearly imagine my behavior as an older sister.
At one point, I left the wedding reception to get some air. I went outside and walked to a nearby playground. I’m not sure how long I sat there before my sister came and joined me. We talked about how we were both grown up. As she wiped a tear from my eye, she lovingly said, “You’ll always be Lucy to me.” We hugged.
Then, my cousin Mike walked over to tell us that it was time to cut the cake, and the second thing that changed my life that day came to pass.
“Hey, did you guys hear that Charles Schulz died today?” he said casually – as if it were no big deal. Then he took my sister’s arm and they turned to head back to the reception hall. “Coming?” they asked. “In a minute,” I replied, and I sat back down on the bench, dizzy from what Mike had just told me.
How could Charles Schulz be dead? He was my creator! He was almost like a father to me!
I had lost so many things on that day. My innocence had slipped away like a thief in the night. It was gone before I could do anything about it, taking with it all the treasures that I had held in my heart. I felt myself grow up in an instant. I saw, for the first time, what I really was – a 30-year-old woman with a husband of my own, and soon, a child of my own.
I took a deep breath and stood up from the bench. I turned and headed back to the hall, hoping I hadn’t missed the cutting of the cake. It was the day that my sister grew wings of her own and left the nest – the day that Lucy died, and I was born.
小題1:Why did the author feel sad at her sister’s wedding?
A.She was afraid of change.
B.Her sister was getting ready to move far away from her.
C.Her wonderful childhood with her sister had become a thing of the past.
D.She had nobody to turn to for help with housework.
小題2:When the author’s cousin told her that Charles Schulz had died, she __________.
A.felt a great sense of loss
B.burst into tears
C.thought he was joking
D.got angry at him for his attitude
小題3:What is implied when the author says that “Lucy died, and I was born”?
A.The author has realized how her sister must have felt about her and decided to change.
B.Lucy no longer matters to the author.
C.The author doesn’t like the nickname Lucy anymore.
D.The author is no longer sad and ready to face the fact that she is an adult.
小題4:The best title of the passage can be __________.
A.Two things changing my life
B.My baby sister’s wedding
C.Not Lucy anymore
D.Not innocent anymore
