Why Do People Shrink？

Did you ever see the movie Honey, I shrunk the kids？ It&39;s about a wacky(古怪的)dad (who&39;s also a scientist) who accidentally(偶然的) shrink&39;s his kids with his homemade miniaturizing (使小型化) invention. Oops! The kids spend the rest of the movie as tiny people who are barely visible while trying to get back to their normal size.

(46) It takes place over years and may add up to only one inch or so off of their adult height (maybe a little more, maybe less), and this kind of shrinking can*t be magically reversed, although there are things that can be done to stop it or slow it down. But why does shrinking happen at all？

(47) As people get older, they generally lose some muscle and fat from their bodies as part of the natural aging process. Gravity (the force that keeps your feet on the ground) take hold, and the bones in the spine, called vertebrae(椎骨), may break down or degenerate, and start to collapse into one another. (48) . But perhaps the most common reason why some older people shrink is because of osteoporosis (骨质疏松症).

Osteoporosis occurs when too much spongy(海绵) bone tissue (which is found inside of most bones) is broken down and not enough new bone material is made. (49) . Bones become smaller and weaker and can easily break if someone with osteoporosis is injured. Older people—especially women, who generally have smaller and lighter bones to begin with—are more likely to develop osteoporosis. As years go by, a person with osteoporosis shrinks a little bit.

Did you know that every day you do a shrinking act？ You aren&39;t as tall at the end of the day as you are at the beginning. (50) . Don&39;t worry, though. Once you get a good night&39;s rest, your body recovers, and the next morning, you&39;re standing tall again.

46

A. They end up pressing closer together, which makes a person lose a little height and become shorter.B. That&39;s because as the day goes on, water in the disks of the spine gets compressed (squeezed) due to gravity, making you just a tiny bit shorter.C. Over time, bone is said to be lost because it&39;s not being replaced.D. Luckily, there are things that people can do to prevent shrinking.E. For older people, shrinking isn&39;t that dramatic or sudden at all.F. There are a few reasons.

请根据短文的内容，回答题。

Some Unusual Celebrations

Some holidays are well-known all around the world. Among them are New Year&39;s Eve celebrations.＜br＞

Also common are days in honor of love and friendship, like Valentine&39;s Day. Each country has its own special holidays, too, often to mark important events in its history. Schools, banks, and government offices all close on days like these. __________ (46) A few of them are really very strange.＜br＞

Of course, they are not strange to the people who celebrate them. Perhaps that is because the celebrations have long traditions. Consider April Fool&39;s Day, for example. No one knows when or why it began. Today it is celebrated in many countries- France, England, and Australia, among others. On this day, people play practical jokes. __________ (47) The ones who laugh are the ones playing the jokes. The people they fool often get angry. Does celebrating this day make sense to you？＜br＞

Day in Poland seems strange, too. On this day, it is traditional for boys to pour water over the heads of girls. Here is the strangest part: They do it to girls they like. Other unusual celebrations take place in a single city or town. A holiday called La Tomatina is celebrated in Bunol, Spain. Every year, in late August, big trucks carry more than 200,000 pounds of tomatoes into this little town. __________ (48)＜br＞

For two hours, people in the streets throw tomatoes at each other. Everyone ends up red from head to toe.＜br＞

August 10 marks the start of the Puck Fair, an Irish festival with a very unusual tradition. People from the town of Killorglin go up into the mountains and catch a wild goat. __________ (49)＜br＞

There are also some celebrations that are really strange. In the United States, sometimes one person gets an idea for a new holiday and tries to get others to accept it. Whose idea was Public Sleeping Day？ That one is on February 28. It may seem strange, but it sounds like more fun than the one on February 9. __________ (50)＜br＞

Do you like the idea of inventing a new holiday？ If you do, then you will want to mark March 26 on your calendar. That is Make Up Your Own Holiday Day.

Humans have always been fascinated by dreams. The vivid dreams people remember and talk ab
out are REM dream—the type that occur almost continuously during periods of rapid eye movement (REM) during sleep. But people also have NREM dreams—dreams that occur during periods without rapid eye movement called NREM sleep—although they are typically less frequent and less memorable than REM dreams. REM dreams have a story like or dream like quality and are more visual, vivid, and emotional than NREM dreams. Interestingly, blind people who lose their sight before age five usually do not have visual dreams, but they have vivid dreams involving the other senses. A popular belief about dreams is that an entire dream takes place in an instant, but in fact, it is not true. Sleep researchers have discovered that it takes about as long to dream a dream as it would to experience the same thing in real life.

Although some people insist that they do not dream at all, researchers say that all people dream unless they consume alcohol or take drugs that suppress REM sleep. Are dreaming and REM sleep essentially one and the same？ Some researchers have questioned an assumption

long held by some sleep experts that dreaming is simply the brain's effort to make sense of the random firing of neurons that occurs during REM sleep. Are the brain mechanisms responsible for REM sleep the same ones that create the rich dream world we experience？ The answer may be no. It is known that dreams do occur outside of REM sleep. Moreover, the REM state can exist without dreams. These two facts suggest that different but complementary brain mechanisms are responsible for REM sleep and the dreaming that normally occurs within it. There is mounting evidence, says British researcher Mark Solms, that dreaming and REM sleep, while normally occurring together, are not one and the same. Rather, the REM state is controlled by neural mechanisms in the brain stem, while areas farther up in the forebrain provide the common pathway that gives us the complex and often vivid mental experiences we call dreams.

Other researchers suggest that REM sleep aids in information processing, helping people sift through daily experience to organize and store in memory information that is relevant to them. Animal studies provide strong evidence for a relationship between REM sleep and learning. Some studies have revealed that animals increase their REM sleep following learning sessions. Other studies have indicated that when animals are deprived of REM sleep after new learning, their performance of the learned task is impaired the following day. But depriving subjects of NREM sleep had no such effect in the studies.

Research has shown that REM sleep serves an information-processing function in humans and is involved in the consolidation of memories after human learning. Researchers found that research participants learning a new perceptual skill showed an improvement in performance, with no additional practice, eight to ten hours later if they had a normal night's sleep or if the researchers disturbed only their NREM sleep. Performance did not improve, however, in those who were deprived of REM sleep.

There is no doubt that REM sleep serves an important function, even if psychologists do not know precisely what that function is. The fact that newborns have such a high percentage of REM sleep has led to the conclusion that REM sleep is necessary for maturation of the brain in infants. Furthermore, when people are deprived of REM sleep as a result of general sleep loss or illness, they will make up for the loss by getting an increased amount of REM sleep after the deprivation. This increase in the percentage of REM sleep to make up for REM deprivation is called a "REM rebound." Because the intensity of REM sleep is increased during a REM rebound, nightmares often occur.

Why does the author state "The answer may be no" in paragraph 2？

A．To introduce a theory that REM sleep and dreams are not necessarily connected.

B．To contrast dreaming before and after REM sleep.

C．To explain why dreaming and REM sleep are essentially the same.

D．To suggest that more dreams occur inside REM sleep than outside it.

It seems like Americans use credit cards for everything. It's a lot easier to spend money
that you don't see, isn't it？ Many Americans spend money that isn't even there and get deeper and deeper in debt. Why do so many people spend more than they have？ "Buy now, pay later" has become an American way of life. Recently, American households spent nearly 11 billion dollars more than they earned, creating a negative saving rate.

There are two ideas—one, living within your means, and the idea that living on debt is a great equalizer(平衡装置). They both have validity because it is important that someone live within their means over their lifetime. When people are young and they are earning money, but they have very little savings, they almost have to borrow in order to own a house or own a car. But as they grow older, they should develop the habit of saving, so that by the time they reach the end of their earning life, they have savings to live on in retirement, and live within their means.

"Buy now, pay later" worked very well for us in the 1990s, but one suspects it won't work forever. The only thing that concerns me is that Americans are so contented, so optimistic, so unconcerned about any bumps in the road that many American households, not all of them, but many American households are very heavily extended in personal credit, a lot of credit card debt. People are paying very high prices for houses and borrowing heavily against those prices; and if we do run into a bump in the road, a recession, there are going to be a lot of households, not all of them, but many households that Ml be severely squeezed. That means we're more vulnerable to serious financial distress than Japan is. Japan has been in financial distress for ten years, but one reason it's been able to weather that is that the households had been very conservative, had a lot of savings, were very liquid, and were able to weather difficult times. And many American households would now be less able to do that because they are so heavily in debt.

We know from the passage that credit cards

A．make Americans get deeper and deeper in debt

B．are likely to be abandoned by more Americans

C．will soon become a symbol of American life

D．will help solve potential financial problems

第6题

We can make mistakes at any age.Some mistakes we make are about money.But most mistake
s are about people."Did Jerry really care when I broke up with Helen？" "When I got that great job, did Jerry really feel good about it, as a friend？ Or did he envy my luck？" When we look back, doubts like these can make us feel bad.But when we look back, it's too late.

Why do we go wrong about our friends--or our enemies？ Sometimes what people say hides their real meaning.And if we don't really listen, we miss the feeling behind the words.Suppose someone tells you, "you're a lucky dog".Is he really on your side？ If he says, "You're a lucky guy" or "You're a lucky gal", that's being friendly.But "lucky dog"？ There's a bit of envy in those words.Maybe he doesn't see it himself.But bringing in the "dog" bit puts you down a little.What he may be saying is that he doesn't think you deserve your luck.

How can you tell the real meaning behind someone's words？ One way is to take a good look at the person talking.Do his words fit the way he looks？ Does what he says square with the tone of voice？ His posture (体态)？ The look in his eyes？ Stop and think.The minute you spend thinking about the real meaning of what people say to you may save another mistake.

1.From the questions in the first paragraph we can learn that tile speaker _____.

A.feels happy, thinking of how nice his friends were to him

B.feels he may not have "read" his friends' true feelings correctly

第9题

A funny thing happened on the way to the communication revolution: we stopped talking

to each other.

1 was walking in the park with a friend recently, and his mobile phone rang, interrupting our conversation. There we were, walking and talking on a beautiful sunny day and - poof! -1 was cut off as if I had become absent from the conversation.

The park was filled with people talking on their cell phones. They were passing people without looking at them, saying hello, noticing their babies or stopping to pat their dogs. It seems that the limitless electronic voice is preferred to human contact.

The telephone is used to connect you to the absent. Now it makes people feel absent.

Recently l was in a car with three friends. The driver hushed the rest of us because he could not hear the person on the other end of his cell phone. There we were, four friends driving down the highway, unable to talk to each other because of the small thing designed to make communication easier.

Why is it that the more connected we get, the more disconnected I feel？ Every advance in communication technology is a setback(退步) to the closeness of human interaction.

With e-mail and instant message over the Internet, we can now communicate without seeing or talking to one another. With voice mail, you can make entire conversations without ever reaching anyone. If my mom has a question, Ijust leave the answer on her machine.

As almost every contact between human beings gets automatic, the emotional Distance index goes up. Pumping gas at the station？ Why say good-morning to the assistant when you can swipe you credit card at the pump and save yourself the bother of human contact？

Making a deposit at the bank？ Why talk to the clerk who lives in the neighborhood when you Ctin put your Ctird into the ATM l More and more, I find myself hiding behind e-mail to do a job meant for conversation orbeing relieved that voice mail picked up because I didn’t really have time to talk.

The technology devoted to helping me keep in touch is making me lonelier. I own a mobile phone, an ATM card, a voice-mail telephone, and an e-mail account.

Giving them up isn’t a choice. They are great for what they are intended to do. It’s their unintended results that make me upset. What good is all this gee-whiz technology if there isno one in the room to hear you crying out Gee whiz ？

26.The author’s experience of walking in a park with a friend recently made him feel ().

A.unhappy

B.funny

C.wonderful

27.According to the author, human contact in a park means ().

A.Iookmg at each other and saying hello when passing

B.noticing their babies and stopping to pat their dogs

C.both A and B

28.According to the author, the more connected we get in communication technology, the () we are.

A.more automatic

B.easier

C.more disconnected

29.What are the examples the author gives to explain his idea that every advance in communication technology is a setback to the closeness of human interaction？()

A.With e-mail and instant message over the Internet, we can now communicate without seeing or talking to one another

B.With voice mail, you can make entire conversations without ever reaching anyone

C.Both A and B

30.What is the unintended result of communication technology, according to the author？()

A.It makes communication easier and conversation possible everywhere

B.It actually creates a distance between people instead of bringing them together

C.It makes every contact between human beings automatic and makes people Feel connected
