A weather map is an important tool for geographers. A succession of three or four maps presents a continuous picture of weather changes. Weather forecasters are able to determine the speed of air masses and fronts（冷暖空气团接触的锋）to determine whether an individual pressure area is deepening or becoming shallow and whether a front is increasing or decreasing in intensity. 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 synoptic 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, droughts, 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 analysis of the upper air levels which often set the stage for the development of air masses, fronts, and storms.
Considerable effort is being exerted today to achieve more accurate weather predictions. With the use of electronic instruments and earth satellites, enormous gains have taken place recently in identifying and tracking storms over regions which have but few meteorological stations (气象站). Extensive experiments are also in progress for weather modification（改变）studies. But the limitations of modification have prevented meteorological results except in the seeding of super-cooled, upslope mountainous winds which have produced additional orographic (山岳形态的) precipitation on the windward side of mountain ranges. Nevertheless, they have provided a clearer understanding of the fundamentals of weather elements.

When middle-aged Alex quit his job and made up his mind to become a self-employed writer, no one could tell for sure whether he would succeed or not．He found a cold storage room in a building, set up a used typewriter and settled down to work．
After a year or so, however, Alex began to doubt himself．He found it was difficult to earn his living by selling what he wrote．But Alex determined to put his dream to the test—even though it meant living with uncertainty and fear of failure．This is the shadowland （虚幻世界） of hope, and anyone with a dream must learn to live there．
One day Alex got a call, "We need an assistant, and we're paying $ 6,000 a year．" $ 6,000 was real money in 1960．It would enable Alex to get a nice apartment, a used car and more．Besides, he could write in his spare time．As the dollars were dancing in Alex's head, something cleared his senses．He had dreamed of being a writer ?full time．"Thanks, but no," Alex said firmly and swiftly, "I'm going to stick it out and write．"
After Alex got off the phone, he pulled out everything he had: two cans of vegetables and 18 cents．Alex put the cans and cents into a paper bag, saying to himself," There's everything you've made of yourself so far．I'm not sure I ever felt so low．"
Finally his work was published in 1970．Instantly he had the kind of fame and success that few writers ever experience．The shadows had turned into focus of attention．
Then one day, Alex found a box filled with things he had owned years before．Inside was a paper bag with two cans and 18 cents．Suddenly he pictured himself working in that cold storage room．It reminds Alex, and anyone with a dream, of the courage and persistence （坚毅） it takes to stay the course （持续到底） in the shadowland．Why did Alex give up his job?
| A．Because he didn't like the working conditions． |
| B．Because he couldn't earn enough to make a living． |

No matter how long your life is, you will, at best, be able to read only a few books of all that have been written, and the few you do read should include the best. You can be pleased with the fact that the number of such is relatively small.
It is to be expected that the selections will change over time. Yet there is a surprising uniformity (一致性) in the lists which represent the best choices of any period. In every age, the list makers include both ancient and modern books in their selections, and they always wonder whether the moderns are up to the great books of the past.
What are the signs by which we may recognize a great book? The four I will mention may not be all there are, but they are the ones I’ve found most useful in explaining my choices over the years.
Great books are probably the most widely read. They are enduring best sellers. Gone with the Wind has had relatively few readers compared to the plays of Shakespeare or Don Quixote. It would be reasonable to estimate that Homer Iliad has been read by at least 25,000,000 people in the last 3000 years.
Great books are popular, not pedantic. They are not written by specialists about specialties for specialists. Whether they are philosophy or science, or history or poetry, they treat of human, not academic problems. They are written for men, not professors. To read a textbook for advanced students, you have to read an elementary textbook first. But the great books can be considered elementary in the sense that they treat the elements of any subject matter. They are not related to one another as a series of textbooks, graded in difficulty or in the technicality of the problems with which they deal.
Great books are always contemporary, the most readable and instructive.
Great books deal with the continuously unsolved problems of human life. There are mysteries in the world that mark the limits of human knowing and thinking. Inquiry not begins with wonder, but usually ends with it also. Great minds acknowledge mysteries only honestly. Wisdom is encouraged, not destroyed, by understanding its limitations.Which is not the criterion in the following when considering a great book?
| A．Although not a best seller, it must be the most widely read． |
| B．A great book can be read without any effort． |
| C．Great books are never out of date． |
| D．Great books will not disappoint you if you try to read them well． |
According to the author, Gone with the Wind is .
| A．a best seller | B．disliked by readers who like Shakespeare |
| C．read more often than Don Quixote | D．a great book |
In the passage the underlined word “pedantic” means ．
| A．showing the feelings, esp., those of kindness, which people are supposed to have |
| B．serving as practical examples |
| C．being elementary |
| D．paying too much attention to details in books |
The best title for this passage is .
| A．Great Books in Your Life | B．Great Books in Your Specialty |
| C．How to Find a Great Book? | D．What Is a Great Book? |

For a commuter rushing to catch a train, a minute can mean the difference between dinner with the family and leftovers (剩饭) in the microwave. What most passengers don’t realize is that their minute is already there.
Every commuter train that departs from New York City — about 900 a day — leaves a minute later than scheduled. If the timetable says 8:14, the train will actually leave at 8:15. In other words, if you think you have only a minute to get that train — well, relax. You have two.
The courtesy (礼貌) minute, in place for decades and published only in private timetables for employees, is meant as a grace period（宽限期）for those who need the extra time to get off the platform and onto the train.
“If everyone knows they get an extra minute, they’re going to waste time doing unimportant things,” explained Marjorie Anders, a spokeswoman for the Metro-North Railroad. Told of this article, Ms. Anders laughed. “Don’t blow our cover!” she said.
Entirely hidden from the riding public, the secret minute is an odd departure from the railroad culture of down-to-the-second accuracy. The railroad industry helped invent the concept of standard time, and time zones were established in the United States in the 1880s, 35 years before they were written into law. And most commuters know their train by the precise minute it departs. The trains quickly make up the minute: at all other stops, the public timetable prevails. The phantom minute does not exist at commuter railroads in Chicago, Los Angeles, Philadelphia, or San Francisco. But in New York, the secret minute dates back decades.
“That’s been done forever, from my knowledge,” said Jack Swanberg, 70, an unofficial historian of Metro-North. “I was the trainmaster starting in 1970 and I’m sure it’s been the case since 1870 for all I know.”The courtesy minute was hidden from the public to _____.
| A．prevent the passengers’ idleness | B．help invent the concept of standard time |
| C．show the railroad company’s consideration | D．follow the ancient tradition of New York City |
The underlined part “Don’t blow our cover” in Para. 4 probably means “_____”.
| A．Don’t publish the timetable | B．Don’t blame commuter trains |
| C．Don’t make it known by the public | D．Don’t forget our chances of catching trains |
What can we conclude from the passage?
| A．The courtesy minute exists in many cities in the US. |
| B．One minute means a lot for most of the commuters. |
| C．The courtesy minute has been in place for about ten years. |
| D．Most railroad staff in New York have no idea of the courtesy minute. |
The passage mainly talks about _____.
| A．the railroads in the US | B．the secret New York minute |
| C．the mistake of the railroad industry | D．the history of New York commuter trains |
The area south of the Thames at Greenwich has a long history. Throughout time different buildings have been constructed on the same site. The Palace of Placentia, an English Royal Palace built in 1447, no longer exists apart from a few remains under the present buildings.
The grand buildings on the South Bank of the Thames at Greenwich were designed by Sir Christopher Wren, most famous for St. Paul’s Cathedral. The buildings were finally completed in 1745, although some parts started to be used as early as 1705. They’re now part of a university — having served as a naval（海军）hospital and a naval college and the setting for several cinemas.
But the buildings stand on a site which has a much longer history, of which now only a part remains that is below the ground. For nearly two hundred years, from around 1450 to 1650, Greenwich was one of the main royal palaces of England. Some of the most famous English rulers, such as Henry VIII and Elizabeth I, not only lived there, but also were born there.
Henry VIII put an armory（兵工厂）there, and there were also gardens, a great fountain (喷泉) and a mass of buildings. The Palace was also in a strategic location, because at the time either side of Greenwich on the Thames were important Royal Dockyards (船厂).
Eventually, though, the Palace fell into disrepair. In 1664, the King at the time, Charles II, decided to replace it with completely new buildings in a modern style. Only a cellar (地窖) from the former Royal Palace now remains, under one of the new buildings. Its red brick, typical of the 16th century, contrasts (对比) sharply with the white stone above it.
