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.

I"ve met colorful people like Wang all over China.They are cynical(玩世不恭的) yet warmhearted, plain spoken but smart.And many of them are confined(局限于)to work in factories.
Wang is a top technician but also represents manual factory workers, who are China"s most important natural resource.Their energy is powering China"s economic boom, and their muscle is turning the wheel of the world"s factory.
But does their unskilled labor give their life meaning? At school, did they tell their friends: "When I grow up I want to work in a factory making socks?" Did you?
Factory work has always been a stepping-stone from farm life to the city and a modern life.It"s been happening for centuries, but today, with our space-age technology, it"s outdated.Earning 1,200 yuan ($169) per month working in a factory is better than that on a farm, but as Wang points out, it"s not a dream career.There should be better ways to earn your rice.
Many modern factories no longer have production line workers.Robots do the assembly(装配).People just do the monitoring.In this age of technology, in which China is now working smarter and not just harder, why are people still standing in production lines?
But life is cheap in China.So why not continue to exploit the low-cost labor situation and keep the economy growing fast, some entrepreneurs may ask.
小题1:How many people surveyed really like to be factory workers?
A.One percent |
B.Only a small part |
C.Only a small part of that one percent |
D.The writer didn’t mention it. |
A.cynical | B.unimportant |
C.warmhearted | D.plain spoken |
A.difficult to get along with |
B.humorous but serious |
C.cynical but warmhearted, plain spoken but smart |
D.full of energy but doesn"t want to work hard |
A.Factory workers make contributions to China"s economic boom. |
B.Working in a factory is better than that on a farm. |
C.Factory workers are satisfied with their living conditions. |
D.Some entrepreneurs exploited the low-cost labor situation. |
A.a lot of figures | B.many examples |
C.some dialogue | D.the result of a survey |
On August 26,1999,New York City was struck by a terrible rainstorm.The rain caused the streets to 51 and the subway system almost came to a stop.
Unfortunately,this happened during the morning rush hour.Many people who were going to work were 52 to go home.Some battled to 53 a taxi or to get on a bus.Still others faced the 54 bravely,walking miles to get to work.
I 55 to be one of people on the way to work that morning.I went from subway line to subway line only to find that most 56 had stopped.After making my way 57 crowds of people,I finally found a subway line that was 58 .Unfortunately,there were so many people waiting to 59 the subway that I could not even get down the stairs to the 60 .So I took the train going in the opposite direction,and then switched back to the downtown train.Finally,after what seemed like forever,the train 61 my stop.Then I had to walk several blocks in the increasingly heavy rain.When I finally got to my office,I was 62 through,exhausted and 63 .
My co-workers and I spent most of the day drying off.When it was 5∶00 pm,I was ready to go home.I was about to turn off my computer 64 I received an email from Garth,my Director:
I would like to thank all of you who made the effort and 65 reported to work.It is always reassuring (令人欣慰),at times like these,when employees so clearly show their 66 to their jobs.Thank you.
Garth’s email was short,but I learned more from that 67 message than I ever did from a textbook.The email taught me that a few words of 68 can make a big difference.The rainstorm and the traffic 69 had made me tired and upset.But Garth’s words immediately 70 me and put a smile back on my face.

A survey of 11,500 people in 18 cities by The Nielson Company found the credit card market had witnessed a major change in recent years.
“Today’s consumer is clearly not interested in saving for a rainy day, as may have been the case in the past,” Bega Ng, director of financial services research with the company said. “Consumers have been adopting Western habits and attitudes in almost every way—including saving and spending habits. Consumers in their 20s spend tomorrow’s cash to fund today’s needs.”
The report found consumers aged 18 to 24 were the most eager credit card users.
Although the report did not give the amounts credit card users in each of the 18 cities spent, it mentioned the example of Xiamen, a coastal city in Fujian Province, where consumers put an average of 50 percent of their monthly incomes into their credit card accounts to indulge(沉湎于) in cashless shopping.
Included in the survey for the first time, Xiamen is reported to have a fast growing penetration rate(渗透率) for credit cards, with four out of ten consumers now owning at least one card. With more than half of cardholders in Xiamen owning two or more cards, it is catching up with key “tier one” cities, the report said. The report did not make known the figures in major cities such as Beijing, Shanghai and Guangzhou.
Last year, the same Nielson survey showed Shanghai had the biggest population of credit card holders, with citizens owning 1.8 credit cards on average. Half of them use credit cards at least once a week, the survey said.
Yunfei, 30, from Beijing, said she spent at least 2,000 yuan a month by credit cards, most of which went on daily necessities and dining out.
小题1:Which of the following best shows the young urbanites’ idea of consumption?
A.Using credit cards in every way. |
B.Spending tomorrow’s cash for today’s needs. |
C.Owning more cards for cashless shopping. |
D.Saving money for future use. |
A.Forty percent of the consumers own at least one card. |
B.Credit card users use up most of their monthly income. |
C.The number of credit card users is larger than that in Guangzhou. |
D.Over half of the consumers use two or more cards. |
A.Xiamen. | B.Beijing. | C.Shanghai. | D.Guangzhou. |
A.Most credit card users are young people aged 18 to 24. |
B.Western habits have a big influence on the Chinese people. |
C.The number of credit card users is growing rapidly in Chinese cities. |
D.Chinese consumers are no more interested in saving money. |
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(能够) 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(充电). 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!
小题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. |
A.Two. | B.Three. | C.Four. | D.It depends. |
A.are smart vehicles | B.are popular vehicle | C.are not practical | D.are not slow |
A.it is just powered by renewable energy | B.it saves money and is eco-friendly |
C.it goes further than a traditional car | D.it is safe, cheap and produces no air pollution |
