A weather map is an important tool for geographers. A succession of three or four maps presents continuous picture of weather changes. Weather forecasters are able to determine the speed of air masses and fronts (气锋) to determine whether an individual pressure aroa is deepening or becoming shallow and whether a front is increasing or decreasing in intensity (强烈).They are also able to determine whether an air mass is retaining its original characteristics or taking on those of the surface over which it is moving. Thus, a most significant function of the map is to reveal a summary picture of conditions in the atmosphere at a given time.
All students of geography should be able to interpret a weather map accurately.Weather maps contain an enormous amount of information about weather conditions existing at the time of observation over a large geographical area. They reveal in a few minutes what otherwise would take hours to describe. The United States Weather Bureau issues information about approaching storms, floods, frosts and all climatic conditions in general. Twice a month it issues a 30-day"outlook" which is a rough guide to weather conditions likely to occur over broad areas of the United States. These 30-day outlooks are based upon an anaiysis of the upper air levels which often set the stage for development of air masses, fronts and storms.
Considerable effort is being exerted today to achieve more accurate weather
predictions, with identifying and tracking storms over regions which have but few meteorological (气象)stations. Extensive experiments are also in progress for weathef modification studies. One characteristic of weather maps NOT mentioned by the author in this passage is_______.
A.floods | B.fronts | C.temperature changes | D.frosts |
The thirty-day forecast is determined by examining________.
A.daily weather maps | B.upper air levels |

A growing number of consumers, especially young people , are adopting more Western habits when it comes to spending money—by favoring credit cards over savings.
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.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. |
How is the situation of credit card use in Xjamen?
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. |
Which city had the largest number of credit card users according to a previous survey?
A.Xiamen. | B.Beijing. | C.Shanghai. | D.Guangzhou. |
What is the main idea of the survey reported by Nielson Company?
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. |
New technology links the world as never before. Our planet has shrunk(收缩). It’s now a “global village” where countries are only seconds away by fax or phone or satellite link. And, of course, our ability to benefit from this high-tech communication’s equipment is greatly enhanced by foreign language skills.
Deeply involved with this new technology is a breed of modern businesspeople who have a growing respect for the economic value of doing business abroad. In modern markets, success overseas often helps support domestic(国内的) business efforts.
Overseas assignments are becoming increasingly important to advancement within executive(行政的) ranks. The executive stationed in another country no longer need fear being “out of sight and out of mind.” He or she can be sure that the overseas effort is central to the company’s plan for success, and that promotions often follow or accompany an assignment abroad. If an employee can succeed in a difficult assignment overseas, superior will have greater confidence in his or her ability to cope back in the United States where cross-cultural considerations and foreign language issues are becoming more and more common.
Thanks to a variety of relatively inexpensive communications devices with business applications, even small businesses in the United States are able to get into international markets.
English is still the international language of business. But there is an ever-growing need for people who can speak another language. A second language isn’t generally required to get a job in business, but having language skills gives a candidate(候选人) the edge when other qualifications appear to be equal.
The employee posted abroad who speaks the country’s principal language has an opportunity to fast-forward certain negotiations, and can have the cultural insight to know when it is better to move more slowly. The employee at the home office who can communicate well with foreign clients(客户) over the telephone or by fax machine is an obvious asset to the firm.
What is the author’s attitude toward high-tech communications equipment?
A.Critical. | B.Indifferent. | C.Negative. | D.Positive. |
With the increased use of high-tech communications equipment, business people_________.
A.have to get familiar with modern technology |
B.are gaining more economic benefits from domestic operations |
C.are placing more importance on their overseas business |
D.are eager to work overseas |
In this passage, “out of sight and out of mind” (Para. 3) probably means _________.
A.being unable to think properly for lack of insight |
B.being totally out of touch with business at home |
C.missing opportunities for promotion when abroad |
D.leaving all care and worry behind |
According to the passage, what is an important consideration of international corporations in employing people today?
A.Connections with businesses overseas. | B.Ability to speak the client’s language. |
C.Technical know-how. | D.Business experience. |
Do you ever run out of great books to read? So what should I read next? Is fast-paced crime fiction your thing?
Try the new Patricia Cornwell book, Scarpetta(Putnam). She is such an able writer and handles complex forensic(法庭的) intelligence with ease. You need to be prepared, though, for the world you're entering—this isn't for the faint of heart, let's say.
If peace is more your thing, try Mary Pipher's wonderful new book, Seeking Peace: Chronicles of the Worst Buddhist in the World (Riverhead).

Thirteen, for me, was a challenging year. My parents divorced and I moved to a new town with my father, far from my old family and friends. I was terribly lonely mad and would cry myself to sleep each night. To ease my sadness, my father purchased an old horse for me at a local auction. I named him Cowboy.
Cowboy was without a doubt the ugliest horse in the world. But I didn’t care. I loved him beyond all reason.
I joined a riding club and suffered rude comments and mean snickers(窃笑) about Cowboy’s looks. I never let on about how I felt, but deep inside, my heart was breaking. The other members rode beautiful, registered horses.
When Cowboy and I entered the events where the horse was judged on appearance, we were quickly shown the gate. No amount of preparation and love would turn Cowboy into a beauty. My only chance to compete would be in the speed events. I chose the jumping race.
One girl named Becky rode a big brown horse in the race events. She always won the blue ribbons. Needless to say, she didn’t feel threatened when I competed against her at the next show. She didn’t need to. I came in next to last.
The stinging memory of Becky’s smirks made me determined to beat her. For the whole next month I woke up early every day and rode Cowboy five miles to the arena (赛马场). We practiced running and jumping for hours in the hot sun and then I would walk Cowboy home totally exhausted.
All of our hard work didn’t make me feel confident by the time the show came. I sat at the gate and sweated it out while I watched Becky and her horse charge through the course and finish in first place.
My turn finally came. I put on my hat, rubbed Cowboy’s neck and entered the arena. At the signal, we dashed toward the first fence, jumped it without trouble and raced on to the next one. Cowboy then flew over the second, third and fourth fences like a bird and I turned him toward the finish line.
As we crossed the line the crowd was shocked into silence. Cowboy and I had beaten Becky and her fancy horse by two seconds!
I gained much more than a blue ribbon that day. At thirteen, I realized that no matter what the odds, I’d always come out a winner if I wanted something badly enough to work for it. The underlined expression "shown the gate" (paragraph 4) most probably means " __________".
A.told how to enter the arena |
B.shown how to make the horse beautiful |
C.removed from the competition early |
D.told to enter the timed-speed events |
Why was the writer not confident of victory?
A.He was an inexperienced rider. |
B.He had not practiced enough. |
C.He believed he was unpopular with the crowd. |
D.He thought his horse wasn’t as good as the others. |
When the final race finished, nobody cheered because____________.

C.the win was unexpected | D.the writer had run out of time |
What did the writer learn from his experience?
A.Life can sometimes be unfair. |
B.Anything is possible if one tries hard enough. |

Batteries can power anything from small sensors to large systems. While scientists are finding ways to make them smaller but even more powerful, problems can arise when these batteries are much larger and heavier than the devices themselves. University of Missouri(MU) researchers are developing a nuclear energy source that is smaller, lighter and more efficient.
“To provide enough power, we need certain methods with high energy density(密度)”,said Jae Kwon, assistant professor of electrical and computer engineering at MU. “The radioisotope(放射性同位素) battery can provide power density that is much higher than chemical batteries.”
Kwon and his research team have been working on building a small nuclear battery, presently the size and thickness of a penny, intended to power various micro / nanoelectromechanical systems (M/NEMS). Although nuclear batteries can cause concerns, Kwon said they are safe.
“People hear the word ‘nuclear’ and think of something very dangerous,” he said, “However, nuclear power sources have already been safely powering a variety of devices, such as pace-makers, space satellites and underwater systems.”
His new idea is not only in the battery’s size, but also in its semiconductor(半导体). Kwon’s battery uses a liquid semiconductor rather than a solid semiconductor.
“The key part of using a radioactive battery is that when you harvest the energy, part of the radiation energy can damage the lattice structure(晶体结构) of the solid semiconductor,” Kwon said, “By using a liquid semiconductor, we believe we can minimize that problem.”
Together with J. David Robertson, chemistry professor and associate director of the MU Research Reactor, Kwon is working to build and test the battery. In the future, they hope to increase the battery’s power, shrink its size and try with various other materials. Kwon said that battery could be thinner than the thickness of human hair.Which of the following is true of Jae Kwon?
A.He teaches chemistry at MU. |
B.He developed a chemical battery. |
C.He is working on a nuclear energy source. |
D.He made a breakthrough in computer engineering. |
Jae Kwon gave examples in Paragraph 4_________.
A.to show chemical batteries are widely applied. |
B.to introduce nuclear batteries can be safely used. |
C.to describe a nuclear-powered system. |
D.to introduce various energy sources. |
Liquid semiconductor is used to _________.
A.get rid of the radioactive waste |
B.test the power of nuclear batteries. |
C.decrease the size of nuclear batteries |
D.reduce the damage to lattice structure. |
According to Jae Kwon, his nuclear battery _______.
A.uses a solid semiconductor |
B.will soon replace the present ones. |
C.could be extremely thin |
D.has passed the final test. |
The text is most probably a ________.
A.science news report | B.book review |
C.newspaper ad | D.science fiction story |
