UFOs Sixty years ago, a man named Kenneth Arnold saw something that we can still 1 today something that changed popular culture for ever. Flying his plane over mountains in the US state of Washington, he saw a line of strange objects, either crescent-shaped (月牙形的) or disc-like, flying 2 the motion of a saucer (碟) skimming (飞速掠过) on water. The media soon picked up on the story—the Flying Saucers were here! Was the earth being 3 by creatures from another planet Soon, So many sightings were made that the US military began to 4 . It called these strange Objects UFOs—Unidentified Flying Objects, and that is how they are 5 today. Military investigations found no evidence of visitors from outer space. But that did not stop the true 6 . The military were 7 up, they said. Or maybe it was because the travelers from space were of such superior intelligence 8 they could hide from military analysts (分析家). People have always seen strange lights in the sky. In the past these were explained in 9 ways. In a world where religion was less influential and science fiction was popular, signs from God were replaced by visitors from other 10 . The date of the first UFO sightings was also significant. In 1947, World War Ⅱ had just ended and the 11 War was just beginning. Humanity seemed locked in endless conflicts. Like generations before them, people looked 12 the skies for help. But instead of seeking God, they looked for help from super-intelligent aliens (外星人) with 13 technology. Belief in UFOs became the first religion of science. However, even people who believe in UFOs are not quite sure why they visit the earth. The universe is a big place and it is 14 to assume that there is life somewhere out there. It is possible that aliens have worked out how to travel through space. Yet some people report that they have been taken by aliens and have had experiments 15 on them. Why would anyone travel across half the universe to conduct medical experiments on people living in small towns in the United States

A. look

In the northern part of Greenland, ice caps, permafrost and gullies dominate the landscape and there’s almost no vegetation. Here became the domain of the Thule who came from Canada in 1200. The onset of the Little Ice Age in the 15th century signaled the end of the Ice Age which started 130,000 years ago. Although the Little Ice Age brought Greenland’s temperatures down by merely 0.8℃, it dealt a lethal blow on the southern regions vegetation and animals succumbed to cold, famine stroke, and European settlements vanished. The Inuit people survived. They intermarried with the Europeans who came later and became the forefathers of Greenland’s people today. The Inuit people still live in pretty much the same way as their ancestors. They make Eskimo canoes. They fish with nets. They hunt seals and sea lions. Sometimes they gut the animals and eat them right on the ice. The innards are precious gifts and are taken back to people of high status and guests. Planet Earth, a critically acclaimed documentary, tells of the impact climate change is having on the ecosystems of the Arctic from the perspective of a polar bear family. The bears are starved on the seaside since they have no sea lions and seals to hunt as glaciers are cracking. The Inuit people are meeting the same fate. Like others, Ajukutoq, a hunter, keeps on complaining to travelers that ice is fast thawing and they are losing the "platforms" they can stand on to hunt animals. They have to use modern fast boats to go further north and look for solid ice surfaces. As the whale population decreases and animals move northwards, whether or not the Inuit’s traditional way of life can continue is thrown into question. Ajukutoq is an elected head of a small town. "Cold has never terrified us, but living on the ’welfare system of the Danish government has," he said. It’s generally accepted that if the global temperature rises by 3℃, Greenland will be submerged, but outspoken opponents of diehard environmentalists argue that even if that temperature rises by 7"C, Greenland won’t be wiped off the face of the earth. Such argument offers valid moral grounds for tapping the resources hidden under Greenland’s ice sheet, and holds an obvious appeal for the people of Greenland who know precious resources lie under their feet but cannot tap those resources under the watchful eyes of the Danish government and environmentalists. According to the last paragraph, why does the argument appeal to some Greenlanders______

A. It may have a soothing effect on their worried minds.
B. It means that Greenland will not be submerged in the years to come.
C. It may help change the Danish government’s resource exploitation policy.
D. It gives them the moral grounds for exploiting the resources under the ice sheet.

Now, we’re always hearing about road accidents, and when we’re in a car, we try to drive carefully, but how many of us take the same degree of care in our homes Any large hospital will tell you the number of accidents that happen in the home is almost the same as those on the road. I don’t pretend to be an expert, but I’ve thought a lot about how and why these accidents happen and what we can do to prevent them. One of the commonest and most dangerous causes of home accidents is wrong and careless use of electrical equipment, People will continue to use a loose plug or pull out a plug without first turning off the power before mending a lamp or something else. All this will cause accidents. So the rule about anything that works by electricity is: switch off before you touch anything and don’t pretend you know when you actually don’t. If you’ve got children on the house, it’s always best to keep medicines of any kind out of their reach. Otherwise, they may be taken for candies or a new kind of drink. When there are older people living with you, you have to take particular care in a number of ways in order to make them safe and happy. Fire, of course, is always a risk. So, remember not to dry clothes in front of fires, or leave stoves in the middle of rooms where they can easily be knocked over. And don’t forget to keep the children away from fire. Smoking, too, may cause fire. So, you’d better give it up. Safety first may mean a little more time and care, but it may save you a lot of trouble. What does the last sentence of the passage imply______

A. The first meaning of "safety" is "time and care".
B. If you have a little more time, you should be more careful.
C. In order to keep safe, it’s worthwhile for people to be more careful and "waste" a little more time.
D. "Safety" can also mean "trouble".

Whether we are aware of it or not, architecture is a part of everybody’s personal history. The chances are that it is in a building that we are born and in which we die; that we work and learn and teach; that we think and make things; that we sell and buy, organize and negotiate, invent things, care for others. Most of us wake up in a building in the morning, go to another building or series of buildings to pass our day, and return to a building to sleep at night. Simply from living in buildings, we all have sufficient knowledge to begin a study of the history of architecture. But before doing so, there is one fundamental point we have to note, which makes architecture both different from the many other different arts and more difficult to judge: it has to be practical as well as attractive, useful on the one hand and beautiful on the other. The word architecture goes back through Latin to the Greek for "master builder". The ancients not only invented the word, but they gave it its clearest and most comprehensive definition in the structures they left behind. According to Vitruvius, a Roman writer, architecture is the union of "firmness, commodity and delight". The first two conditions are concerned with the down-to-earth side of architecture-its structural practicality. The third deals with its visual or aesthetic aspect. Without "firmness", it is dangerous; without "commodity", it is merely large-scale sculpture; and without "delight", it is just a building. For any given building, all three conditions are vital, but the history of architecture shows that they were not always of equal interest to the peoples of different periods. Some periods were structurally innovative, the buildings of the Romans, for example, while others, such as those of the Greeks, tended to accept inherited structural methods with comparatively little change or advancement. The changing function of buildings also varies greatly from period to period. Once the patterns of use of certain long-lived types, such as Hindu temples, Christian churches or the modern office block, are established, it is only usually minor functional changes that follow. According to the passage, the Romans ______.

A. had little interest in changing the function of their buildings
B. liked the ancient structure of the buildings
C. tended to accept inherited structural methods
D. tended to change the function of the buildings

Directions: Scan the following passage and find the words which have roughly the same meanings as those given below. The number in the brackets after each word definition refers to the number of paragraph in which the target word is. Write the word you choose on the Answer Sheet. Since their first appearance on earth, men have gathered information and have attempted to pass useful ideas to other men. The carving of word-pictures on the walls of ancient caves as well as hieroglyphics on stone tablets represent some of men’s earliest efforts to convey information. Scenes of hunting, maps of battles, and the stories of heroes were put down for all to see. But as civilizations grew more complex, better methods of communication were needed. The written word, carrier pigeons, the telegraph, and many other devices carried ideas faster and faster from man to man. In recent years one type of machine, the electronic computer, has become increasingly important in the lives of all the people in the industrialized nations of the world. Computers are now widely used aids for communication, calculation, and other activities. Their effect becomes more important every day. New ways of helping with counting and recording information evolved. Marks of different kinds were taken to represent certain quantities, and other marks were taken to represent relationships between quantities. New devices to aid in the manipulation of numbers were developed. Old lines and methods of communication do not work easily or efficiently with as much information as we have now. The repeated actions of preparing, sorting, filling, distributing, and keeping track of records and publications can be as troublesome as calculating. Errors occur because men grow tired and can be distracted. something thought out, invented or adapted, for a special purpose (Para. 2)
