Thousands of villages in the developing world have no telephones. They have no money to build telephone systems. A new kind of technology may help change this situation. I t reduces the cost of building and using telephone systems.
Traditional systems use wires to carry electrical signals from one telephone to another. The wires often cost much more than telephones. The new system is based on radio communication. Each telephone sends and receives signals through the air, but not through the wires. This reduces the cost greatly. The radio telephone gets their power from the sun.
Each is connected to a solar equipment that changes the sun’s energy into electricity. A battery stores the electricity until someone needs to make or receive a call. The telephone turns off by itself if the level of power in the battery falls too low. This prevents damage to the system. Each radio telephone is connected to a computer microprocessor. It rewards how many calls are sent and received. It controls the power supply.
The technology needs more study, but its new use of radio equipment sun power and computers may help start telephone ringing in the other parts of the world.
68. The radio telephone gets their power from_____.
A. the sun 　　　B. electricity 　　　C. battery 　　　D. a special equipment
69. Each telephone is connected to_____.
A. a solar equipment 　　　　　　　B. a radio machine
C. a computer microprocessor 　　　D. Both A and C
70. From the passage we can infer that_____.
A. the new telephone system costs less than before
B. we can not use the radio as before
C. the new telephone system will take the place of the old one
D. it will be much easier to radio from now on
71. The main idea of the passage is_____.

第一節(jié)：閱讀理解：閱讀下列短文，從每題所給的A、B、C和D項(xiàng)中，選出最佳選項(xiàng)，并在答題卡上將該項(xiàng)涂黑。
The relations between man and wife are changing. A majority of working women remain in full charge of their home; they come back at night to the cleaning, washing, and cooking that constitute their second career. But more and more husbands are sharing the burden and willingly taking on chores that their fathers would rejected as unmanly, and as too mysteriously difficult anyway. In such cases, man and wife become equal partners, both working outside, both pushing the vacuum cleaner. Actually, the number of husbands who do help that way is much smaller than the number of those who accept the idea in theory. And when the equal partnership is a fact, it doesn’t always work well. The marriage can be destroyed when the wife is more successful in her profession than her husband in his, particularly when she earns more than he does. Sociologists see in this situation one of the main reasons for the increase in the divorce rate—another reason being the husband’s refusal to help with the housework or the care of the children. A third reason could be the growing awareness of the professional woman that she doesn’t have to remain married if she is too unhappy.
61. What is the housework like in the traditional husband’s eyes?
A. It’s a mysterious job.
B. It’s a little difficult
C. It’s women’s job.
D. It’s only men’s job.
62. The underlined sentence means________________.
A. When man and wife share the housework, man can’t do it well.
B. When man and wife share the housework, women can’t do it well.
C. when man and wife become equal at home, it doesn’t mean a good marriage.
D. when man and wife are equal partners, marriage doesn’t necessarily go well.
63. All of the following statements are true EXCEPT______________.
A. more husbands act in helping housework than those agreeing it without action.
B. more and more husbands are helping their wives to do housework.
C. most of the working women take charge of their house.
D. it is possible for the marriage to fail if women earn more money than husbands.
64. What may be the reason for the divorce according to the sociologist?
A. The wife refuses to look after the child.
B. The wife is more successful than her husband.
C. The wife is aware of her unhappiness in marriage.
D. Both A and B.
65. The best title of the passage is most likely to be___________.
A. Equal Partnership Means Nothing in Modern Family.
B. The Changing Relations between Man and Wife.
C. Reasons for Increasing Divorce.
D. The Relations between Husband and Wife.

   As many as one in five US teenagers have some degree of hearing loss, according to researchers.
They say the problem is growing.
Teenagers really don’t pay attention to how much noise they are exposed (暴露) to, Josef Shargorodsky of Brigham and Women’s Hospital in Boston told Reuters. “Often people won’t notice it, but even slight hearing loss may affect language development,” said Shargorodsky, one of the researchers.
The study compared surveys from the early 1990s and the mid-2000s. Each included a few thousand teenagers. In the first survey, about 15 percent of teenagers had some degree of hearing loss. Some 15 years later, that number had risen by a third, to nearly 20 percent.
“This certainly is big news,” said Alison Grimes, an ear doctor. Hearing loss is very common in old people, Grimes said, but she added that it was worrying to see it happen in the younger age group.
In babies and young children, hearing problems are known to slow language development. The science is less clear for teenagers, but it is easy to imagine how being hard of hearing could affect learning, said Grimes,.
The reasons for the rise are still unclear. When researchers asked teenagers about noise exposure – on the job, at school or from activities, for example – the teenagers didn’t report any change. But Shargorodsky said that might not be true. “We knew from before that it is difficult to ask this age group about noise exposure – they underestimate (低估) it.” Few people would call it noise when they listen to music on their MP3 player, for example. “There is a difference between what we think is loud and what is harmful to the ear,” said Grimes.
Although it’s not clear that the MP3 players cause teenagers’ hearing loss, Grimes said it was still a good idea to turn down the sound and take short breaks from listening.
小題1:According to the researchers, in a US class of 40 students, about ____ students have some degree of hearing loss.
A．oneB．fiveC．sixD．eight
小題2:Which of the following statements is true according to the article?
A．Slight hearing loss does not influence learning.
B．Only a few old people have hearing problems.
C．Hearing problems can slow language development.
D．Noise exposure is clearly noticed by teenagers.
小題3:About hearing loss, it can be inferred that ________.
A．the reasons for the rise have been foundB．MP3 players are to blame
C．listening to loud music may be a causeD．noise is the main reason
小題4:The article was written to ______.
A．warn teenagers that loud music might be harmful
B．explain what kinds of noises might affect studies
C．suggest that teenagers shouldn’t listen to loud music
D．show how important hearing can be for learning

They wear the latest fashions with the most up-to-date accessories(配飾)．Yet these are not girls in their teens or twenties but women in their sixties and seventies．A generation which would once only wear old-fashioned clothes is now favouring the same high street looks worn by those half their age．
Professor Julia Twigg, a social policy expert, said, “Women over 75 are now shopping for clothes more frequently than they did when they were young in the 1960s．In the 1960s buying a coat for a woman was a serious matter．It was an expensive item that they would purchase only every three or four years — now you can pick one up at the supermarket whenever you wish to．Fashion is a lot cheaper and people get tired of things more quickly．”
Professor Twigg analysed family expenditure(支出) data and found that while the percentage of spending on clothes and shoes by women had stayed around the same — at 5 or 6 percent of spending — the amount of clothes bought had risen sharply．
The professor said, “Clothes are now 70 percent cheaper than they were in the 1960s because of the huge expansion of production in the Far East．In the 1960s Leeds was the heart of the British fashion industry and that was where most of the clothes came from, but now almost all of our clothes are sourced elsewhere．Everyone is buying more clothes but in general we are not spending more money on them．”
Fashion designer Angela Barnard, who runs her own fashion business in London, said older women were much more affected celebrity(名流) style than in previous years．
She said, “When people see stars such as Judi Dench and Helen Mirren looking attractive and fashionable in their sixties, they want to follow them．Older women are much more aware of celebrities ．There’s also the boom in TV programmes showing people how they can change their look, and many of my older customers do yoga to stay in shape well in their fifties．When I started my business a few years ago, my older customers tended to be very rich, but now they are what I would call ordinary women．My own mother is 61 and she wears the latest fashions in a way she would never have done ten years ago．”
小題1:Professor Twigg found that, compared with the 1960s, _________．
A．the price of clothes has generally fallen by 70%
B．the spending on clothes has increased by 5% or 6%
C．people spend 30% less than they did on clothes
D．the amount of clothes bought has risen by 5% or 6%
小題2:What can we learn about old women in terms of fashion？
A．They are often ignored by fashion designers．
B．They are now more easily influenced by stars．
C．They are regarded as pioneers in the latest fashion．
D．They are more interested in clothes because of their old age．
小題3:It can be concluded that old women tend to wear the latest fashions today mainly because _________．
A．they get tired of things more quicklyB．TV shows teach them how to change their look
C．they are in much better shape now D．clothes are much cheaper than before
小題4:Which is the best possible title of the passage?
A．Age Is No Barrier for Fashion Fans B．The More Fashionable, the Less Expensive
C．Unexpected Changes in FashionD．Boom of the British Fashion Industry

I began to work as a salesgirl in a department store. I got there that morning and was introduced to all the salesmen and saleswomen.

Today’s drivers may feel shocked by the high price of petrol when they drive to the gas station. However, the car industry has the technology to solve the problem. It’s the hybrid car（混合動(dòng)力汽車(chē)）.
What is a hybrid car? Any car that uses two or more sources of power is a hybrid car. Most hybrid cars on the road right now are petrol-electric hybrids. The petrol-electric hybrid car is just what it sounds like — a cross between a petrol-powered car and an electric car.
A gas-powered car has a fuel tank（油箱）, which supplies petrol to the engine. An electric car, on the other hand, has a set of batteries that provides electricity for the car.
To be useful to you or me, a car should be able to run at least 300 miles (483 km) before refueling, be capable of(能夠) being refueled quickly and easily and fast enough to keep up with the other traffic on the road.
A petrol car meets these requirements（要求）but produces a large amount of pollution. An electric car, however, produces almost no pollution, but can only go 50 to 100 miles (80 to 161 km) between recharging(充電). And the problem has been that the electric car is very slow and inconvenient to recharge.
A petrol-electric car combines the advantages of the two power sources into one system that uses both gas power and electric power. Some experts believe that the hybrid car is “the next generation of smart cars”. A hybrid car can go up to 50% further than a traditional car can on the same amount of gas! It saves driver’s money on gas and cuts air pollution!
小題1:What do the underlined words “the problem” in Paragraph 1 refer to?
A．The price of petrol goes up and down.B．The gas-powered car is sold at a high price.
C．The gas-powered car causes air pollution.D．The price of petrol keeps going up.
小題2:How many sources of power do most hybrid cars use?
A．Two.B．Three.C．Four.D．It depends.
小題3:The author thinks that electric cars _____.
A．a(chǎn)re smart vehiclesB．a(chǎn)re popular vehicleC．a(chǎn)re not practicalD．a(chǎn)re not slow
小題4:Some experts believe that the hybrid car will have a large market in future because _____.
A．it is just powered by renewable energyB．it saves money and is eco-friendly
C．it goes further than a traditional carD．it is safe, cheap and produces no air pollution

I was parked in front of the mall wiping off my car. Coming my way from across the parking lot was what society would consider a bum (乞丐). “I hope he doesn’t ask me for any money,” I thought.
He didn’t. He came and sat on the curb (路邊) in front of the bus stop but he didn’t look like he could have enough money to even ride the bus.
After a few minutes he spoke,“That’s a very pretty car.” He was ragged (衣衫襤褸的) but he had an air of dignity.
I said “Thanks” and continued wiping off my car. He sat there quietly as I worked. “Do you need any help?” I asked.
He answered in three simple but profound words that I shall never forget.
“Don’t we all?” he said.
I was feeling high and mighty, successful and important, above a bum in the street, until those three words hit me like a shotgun.
Don’t we all?
I needed help. Maybe not for bus fare or a place to sleep, but I needed help. I reached in my wallet and gave him not only enough for bus fare, but enough to get a warm meal and shelter for the day.
Maybe the man was just a homeless stranger wandering the streets. Maybe he was more than that. Maybe he was sent by a power that is great and wise, to minister to a soul too comfortable with himself.
Don’t we all? Those three little words still ring true. No matter how much you have, no matter how much you have accomplished, you need help too. And you never know when you may see someone that appears to have it all. They are waiting for you to give them what they don’t have.
1. What was the writer doing when he met the homeless person?
A. Shopping.       B. Cleaning his car.       C. Admiring his car.      D. Parking his car.
2. What does the underlined phrase “high and mighty” mean?
A. Tall.   B. On top of the world.C. Strong and powerful.  D. Filled with false pride.
3. Which of the following can best describe the writer’s feelings about himself after the encounter?
A. He felt a new sense of pride.                  B. Inspired and humble.
C. Great and wise.                            D. Successful and important.
4. What does the article tell us?
A. We should help those less fortunate than ourselves.
B. Helping a person indirectly is preferable to direct, obvious help.
C. All of us, at certain moments of our lives, need help from others and should offer help ourselves.
D. Money is all important in life.

A German company was concerned about talks in Moscow trying to sell some 100 million dollars worth of equipment to a Russian State company. Talks went smoothly but differences remained. So Martin Bayer himself, the CEO of the German Company, decided to come to Moscow to head the talks. Besides caring about his business, the CEO wanted to go to Russia to hunt bears.
Martin Bayer was one of the greatest hunters of our time (and the Russians knew about it). He went to the Sahara more than hundred times and hunted lions, crocodiles; he hunted polar bears in the North Pole and tigers in the rain forests of India. But he had never hunted Russian bears.
So the Russians decided to organize a bear hunt for Mr. Bayer to sweeten the talks. This wasn't a simple task. Some people in the west still believe that bears may be found and seen everywhere in Russian cities just like squirrels may be seen in our back yards. This is not true. The closest place one may find bears in the wild is maybe 2,500 miles away from Moscow. However, a solution was quickly found. The Russian businessmen went to Moscow Circus（馬戲團(tuán)）and for $2,000 bought a very old bear. This bear used to amuse and amaze audiences in many countries for 30 years, but got and looked too old, and was retired.
“Be careful, the Russian bears are very dangerous, and frightening,” they told to Mr. Bayer. “If compared to the Russian bears, your African lions are nothing more than harmless cats.” The bear was brought to a forest 50 miles from Moscow and was left there. Mr. Bayer was told that bears were plentiful in that forest and that many cattle and even people had been eaten in the surrounding villages.
Meanwhile, an 18-year old female drove through the forest on a motorcycle and suddenly saw a bear (no bears had been seen in those places for 200 years). She was frightened, fell, left her helmet and her motorcycle and ran away.
Mr. Bayer was excited and ready to hunt. This could become the most successful part of his extraordinary hunting experience. The next moment Mr. Bayer saw a bear in a helmet driving on a motorcycle through the forest in front of him. The bear had a happy expression on his face, as he was doing something he had been doing in the circus for 30 years: circling on a motorcycle!
Mr. Bayer lives in a private mental institution near Hamburg happily ever after. The equipment was never sold to Russia. It was sold to Iraq instead.
1. Why did the Russians invite Mr. Bayer to hunt bears?
A. Russian bears are famous for their cruelty.
B. They managed to find a bear for hunting.
C. They expected the trade to be successful.
D. There was a bear in Moscow Circus.
2. Why did the Russians say “Be careful, the Russian bears are very dangerous, and frightening”?
A. To tell Mr. Bayer that many people had been killed by bears.
B. To make Mr. Bayer feel the hunting really challenging.
C. To warn Mr. Bayer to mind his safety while hunting.
D. To tell Mr. Bayer that the bear is really dangerous.
3. We can infer from the last paragraph that __________.
A. Mr. Bayer has gone ma   
B. the bear injured him badly
C. he has worked in a mental institution since then
D. the trade has gone smoothly between Russian and Iraq
4. Which would be the best title of the passage?
A. Mr. Bayer, a Brave Hunter     B. Russian Bears, Dangerous Animals
C. Don’t Hunt in Russia       D. Don’t Deal with the Russians
