Uncertainty spreads through our lives so thoroughly that it dominates our language，Our everyday speech is made up in large part of words like probably, many, soon,great,little.What do these words mean?
Such verbal imprecision is not necessarily to be criticized. Indeed, it has a value Just because it allows uw to express judgments when a precise quantitative statement is out of the question.
We have been trying to pin down by experiments what people meari by these expressions in specific contexts, and how the meanings change with age. For instance,a subject is told "There are many trees in the park" and is asked to say what number the word may mean to him. Or a child is invited to take "some" sweets from a bowl and we then count how many he has taken. We compare the number he takes when he is alone with the number when one or more other children are present and are to take some sweets after him, or with the number he takes when told to give
“some" sweets to another child.
First, we find that the number depends, of course, on the items involved. To most people some friends means about five, while some trees means about twenty. However, unrelated areas sometimes show parallel values. For instance, the language of probability seems to mean about the same thing in predictions about the weather and about politics: the expression is certain to( rain,or be elected)signifies to the average person about a 70 percent chance; is likely to, about a 60 percent chance; probably will, about 55 percent.
Secondly, the size of the population of items influences the value assigned to an expression.Thus, if we tell a subject to take "a few" or“a lot of" glass balls from a box, he will take me if the box contains a large number of glass balls than if it has a small number, But not proportionately more: if we increase the number of glass balls eight times, the subject takes only half as large a percentage of the total.
Thirdly, there is a marked change with age. Among children between six and fourteen years old, the older the child, the fewer glass balls, he will take. But the difference between a lot and a few widens with age. This age effect is so consistent that it might be used as a test of intelligence.
51. What's the right attitude towards the words like probably, any and soon ?
A. They are inaccurate and we should avoid them.
B. They are necessary since we cannot be always precise.
C. They should be criticized because there are too many of them.
D. Their value is not yet clear since we don't know their meaning.
52. Why do we do experiments with the words many and some?
A. To prove that people are insensitive to these words.
B. To prove that the words dominate our everyday speech.
C. To find out how the meanings vary with age and contexts.
D. To find out whether the words can mean a precise quantity.
53. Which of the following expressions means a larger chance in weather broadcast?
A. Possible. B. Probable. C. Be likely to. D. Be certain to.
54. Which of the following is similar to the underlined word signifies in its meaning?
A. makes B. means C. predicts D. indicates

There is a story about a man who lost his legs and left arm in an accident. After the accident, only a finger and thumb on his right hand remained.
He was a brilliant, creative, and educated man. He had gained a lot of experience while traveling around the world, so he became very depressed after his accident. He was afraid that he would spend the rest of his life suffering and would no longer be able to spend his life in a meaningful way. Then, he realized that he still had partial function of his right hand and could still write even though it was very difficult. An idea occurred to him. "Why not write to other people who need encouragement?"
He wrote to the prison ministry about sending letters to the prisoners. The prison minister replied, "Writing to the prisoners is acceptable, but your letters will not be answered."
Filled with excitement, the man knew he could write his letters. He began sending one-way messages of God’s love, hope, strength, and encouragement. He wrote twice a week, testing his strength and ability to the limit. He poured his heart and soul into his words and shared his experience, sense of humor, optimism, and faith.
It was difficult to write those letters, especially without hope of a reply. One day he received a letter from the prison ministry. It was a short note from the officer who monitored and checked the prison mail.
The letter said, "Please write on the best paper you can afford. Your letters are passed from cell to cell until they literally fall to pieces!"

Whether we should allow marine (海洋的) parks to stay open has been widely debated in our community recently. A variety of different arguments have been put forward about it.
Smith, a sociologist, argued that dolphin parks provide the only opportunity for much of the public to see marine mammals. As this argument goes, most Australians live in cities and never get to see these animals. Marine parks allow the average Australian to appreciate our marine wildlife. However, in fact, there are many places where they can be seen in the wild. Moreover, these places do not charge an overpriced entry fee — they are free.
Dr. Alison Lane, the director of the Cairns Marine Science Institute, insists that we need marine parks for scientific research. She argues that much of our knowledge of marine mammals comes from studies which were undertaken at marine parks. The knowledge which is obtained at marine parks can be useful for planning for the preservation of marine mammal species. However, Jones, a zoologist, explains that park research is only useful for understanding captive animals and is not useful for learning about animals in the wild. Their diets are different, they have significantly lower life lengths and they are more likely to have a disease. In addition, marine mammals in dolphin parks are trained and this means that their patterns of social behaviour are changed.
The Marine Park Owners Association holds that marine parks attract a lot of foreign tourists. This position goes on to state that these tourists spend a lot of money, increasing our foreign exchange earnings and assisting our national balance of payments. However, foreign tourists would still come to Australia if the parks were closed down. Indeed, surveys of overseas tourists show that they come here for a variety of other reasons and not to visit places like Seaworld. Tourists come here to see our native wildlife in its natural environment and not to see it in cages and concrete pools. They can see animals in those conditions in their own countries.
In a word, perhaps an agreement cannot be reached now. However, a question does deserve our consideration: If we continue with our past crimes against these creatures, how will our future generations view us?Who support(s) the idea of closing marine parks?
| A．Most Australians. | B．Alison Lane. | C．Smith. | D．Jones. |
What does the author intend to tell us in Paragraph 3 ?
| A．The results from studies are valuable in animal preservation. |
| B．Scientific research at the marine parks has its limitations. |
| C．Captive animals have biology changes in marine parks. |
| D．Human behavior causes harmful effects on the animals. |
Which is NOT the reason to keep marine parks?
| A．For entertainment purpose. | B．For scientific research purpose. |
| C．For economic purpose. | D．For political purpose. |
The author tries to persuade readers to accept his argument mainly by .
| A．pointing out the problems with keeping the marine parks |
| B．using evidence he has collected at the marine parks |
| C．discussing the advantages of animals' natural homes |
| D．questioning the way the animals are studied |
Now Hear This
What do former American president Bill Clinton and rock musician Pete Townshend have in common.'? Both men have hearing damage from exposure to loud music, and both now wear hearing aids as a consequence. 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 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 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 (分贝) 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 conversation50 — 65 dB Food blender 88 dB Jet plane flying above a person standing outside 103 dB Rock band during a concert 110 — 140 dB |

| A．loud music is a major cause of hearing loss |
| B．famous people tend to have hearing problems |
| C．teenagers should stay away from school bands |
| D．the problem of hearing damage is widely known |
In Paragraph 3, the underlined word "recondition" means .
| A．not to be seen | B．to fill with sound |
| C．to become larger in size | D．to make good again |
The purpose of the chart at the end of the article is to show .
| A．a list of harmful sounds |
| B．the effect of rock concerts |
| C．the noise levels of familiar sounds |
| D．relationship between daily activities and hearing loss |
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 taking the risk of losing hearing. |
| D．Doctors know how to cure hearing loss. |
Car Talk
When I got the driving license last summer, Mom and I took our first trip around an empty parking lot. Then I found that my mother was not the best teacher for me. It wasn't that she shouted, or told me that I was doing poorly. As you can imagine, my mother's "helpful instructions" only managed to make me more nervous.
Since I could no longer practice with her, the job was placed in the hands of my father. The idea of learning from Dad was not one that thrilled me. I loved him dearly, but I just did not see Dad as someone I could be comfortable learning from. He almost never talked. We shared a typical father-daughter relationship. He'd ask how school was, and I'd say it was fine. Unfortunately, that was the most of our conversations. Spending hours alone with someone who might as well have been a stranger really scared me.
As we got into the car that first time, I was not surprised at what happened. Dad and I drove around, saying almost nothing, aside from a few instructions on how to turn. As my lessons went on, however, things began to change. Dad would turn the radio up so I could fully appreciate his favorite Stones music. And he actually began talking. I was soon hearing about past failed dates, "basic body" gym class, and other tales from his past, including some of his first meeting with Mom.
Dad' s sudden chattiness was shocking until I thought about why he was telling me so much in the car. In all the years that I had wondered why my father never spoke that much, I had never stopped to consider that it was because I had never bothered to listen. Homework, friends, and even TV had all called me away from him, and, consequently, I never thought my quiet father had anything to say.
Since I began driving with him, my driving skill has greatly increased. More important, though, is that my knowledge of who my father is has also increased. Just living with him wasn't enough—it took driving with him for me to get to know someone who was a mystery.The author couldn't practice driving with her mother because .
