单选题 On June 17,1744, the officials from Maryland and Virginia held a talk with the Indians of the Six Nations. The Indians were invited to send boys to William and Mary College. In a letter the next day they refused the offers as follows: We know that you have a {{U}}(26) {{/U}} opinion of the kind of learning taught in your colleges, and that the {{U}}(27) {{/U}} of living of our young men, while {{U}}(28) {{/U}} you, would be very great to you. We are {{U}}(29) {{/U}} that you mean to do us {{U}}(30) {{/U}} by your proposal; and we thank you {{U}}(31) {{/U}}. But you must know {{U}}(32) {{/U}} different nations have different ways of looking at things, and you will {{U}}(33) {{/U}} not be {{U}}(34) {{/U}} if our ideas of this kind of education happen {{U}}(35) {{/U}} be the same as yours. We have had some experience of it. Several of our young people were {{U}}(36) {{/U}} brought {{U}}(37) {{/U}} at the colleges of the northern provinces: they were taught all your sciences; but, when they came back to us, they were bad runners, {{U}}(38) {{/U}} of every means of living in the woods — they were totally {{U}}(39) {{/U}} for nothing. We are, however, {{U}}(40) {{/U}}, {{U}}(41) {{/U}} by your kind {{U}}(42) {{/U}}, though we refuse to accept it; and, to show our grateful sense of it, if the gentlemen of Virginia will send us a {{U}}(43) {{/U}} of their sons, we will take care of their education, teach them in {{U}}(44) {{/U}} we know, and make {{U}}(45) {{/U}} of them.

单选题 In United States it is not customary to telephone someone very early in the morning. If you call him early in the day, while he is shaving or having breakfast, the time of the call shows that the matter is very important and requires immediate attention. The same meaning is attached to telephone calls made after 11:00 p. m. If someone receives a call during sleeping hours, he assures it is a matter of life or death. The time chosen for the call communicates its importance. In social life, time plays a very important role. In United States, guests tend to feel they are not highly regarded if the invitation to a dinner party is extended only three or four days before the party date. But this is not true in all countries. In other areas of the world, it may be considered foolish to make an appointment too far in advance because plans which are made for a date more than a week away tend to be forgotten. The understanding of time differ in different parts of the world. Thus, misunderstanding arise between people from cultures that treat time differently. Promptness is valued highly in American life, for example, if people are not prompt, they may be regarded as impolite or not fully responsible. In the U. S. , no one would think of keeping a business associate waiting for an hour, it would be too impolite. When equals meet, a person who is five minutes late is expected to make a short apology. If he is less than five minutes late, he will say a few words of explanation, though perhaps he will not complete the sentence. To Americans, forty minutes of waiting is the beginning of the "insult period". No matter what is said in apology, there is little that can remove the damage done by an hour' s wait. Yet in some other countries, a forty minutes waiting period was not unusual. Instead of being the very end of the allowable waiting scale, it was just the beginning. Americans look ahead and are concerned almost entirely with the future. However, the American idea of the future is limited. It is the foreseeable future and not the future of South Asian, which may involve, centuries. Someone had said: "Time is like a museum with endless halls and rooms. You, the viewer, are walking through the museum in the dark, holding a light to each scene as you pass it. God is in charge of the museum, and only he knows all that is in it. One lifetime represents one room. " Since time has different meanings in different culture, communication is often difficult. We will understand each other a little better if we can keep this fact in mind.

单选题According to the author, the bottom line for having too much money is ______.

单选题Amphibious vehicles, those that can move on both land and water, have been in use for a number of years, but while most of them were fairly fast on land, they moved quite slowly when they were functioning as boats. The only truly amphibious vehicle that can move with equal ease on both land and water is the hovercraft (气垫船). The hovercraft is the invention of an electronics engineer named Christopher Cockerell. Cockerell's hobby was sailing and he was interested in the problem of reducing the friction of water on the body of a boat, and hit on the idea of designing a boat which would travel on a cushion of air. The air cushion under a hovercraft is produced by a large fan which blows air downwards between the craft and the water or ground, and so lifts up the craft. The air is main-rained at higher than atmospheric pressure by a flexible rubber "skirt" around the bottom edge of the hovercraft, preventing leakage of air from the cushion. Because the hovercraft floats on the air cushion with no contact between the craft and the surface below, it can travel over flat, rough ground or water with ease. Hovercraft are usually driven by air screws like propellers (螺旋桨), which face back-wards and "push" the craft forwards, and can be turned to direct the hovercraft. Since there is no propeller dipping below the craft, hovercraft can travel up slopes out of the water, or land on beaches. Cockerell's Air Cushion Vehicles, or ACVs, are now familiar to everyone and like all inventions, they have been improved upon. British Sea speed hovercraft have been carrying passengers and cars across the English Channel since 1968. They now have a "stretched" version of their Mountbatten Class hovercraft which can carry up to 60 cars and 416 passengers between Britain and France in a little over half an hour. A new, large-sized hovercraft, designed and built in France, called the Sedam N500 of Naviplane, has now goneinto service. The 155 tonne N500 is 50 metres long (162 feet) and 23 metres wide (76 feet) and can carry 65 cars, plus five coaches, together with 400 passengers. When the sea conditions are ideal the N500 can reach 112 kph (70 mph). A variation of the hovercraft principle is the sidewall ACV, which is more economical than the flexible skirt models, and easier to control, but it cannot be used on land. The United States Navy have been experimenting with warships based on the sidewall principle, and some of these may well reach a speed of 160kph (100mph).

单选题Questions 14-17 are based on the following dialogue.

单选题 Centuries ago, man found out that removing moisture from food helps to preserve it, and that the easiest way to do this is to expose the food to sun and wind. All foods contain water—cabbage and other leaf vegetables contain as much as 92% water, potatoes and other root vegetables 80%, lean meat 70% and fish anything from 80% to 60% depending on how fatty it is. If this water is removed, the activity of the bacteria(细菌) which cause food to go bad is checked. At present most foods are dried mechanically. The conventional method of such dehydration (脱水) is to put food in chambers through which hot air is blown at temperature of about 110℃ at entry to about 43℃ at exit. This is the usual method for drying such things as vegetables, minced meat and fish. Liquids such as milk, coffee, tea, soup and egg may be dried by pouring them over a heated horizontal steel cylinder or by spraying them into a chamber through which a current of hot air passes. In the first case, the dried material is stripped off the roller as a thin film which is then broken up into small, though still relatively coarse flakes. In the second process it falls to the bottom of the chamber as a fine powder. Where recognizable pieces of meat and vegetables are required, as in soup, the ingredients are dried separately and then mixed. Dried foods take up less room and weight less than the same food packed in cans or frozen, and they do not need to be stored in special conditions. For these reasons they are invaluable to climbers, explorers and soldiers in battle, who have little storage space, they are also popular with housewives for it takes so little time to cook them. Usually it is just a case of replacing the dried-out moisture with boiling water.

单选题Television has opened windows to everybody. Young men will never again go to war as they did in 1914. Millions of people now have seen the effects of a battle. And the result has been a general dislike of war, and perhaps more interest in helping those who suffer from all the terrible things that have been shown on the screen. Television has also changed politics. The most remote can now follow state affairs, see and hear the politicians before an election. Better informed, he is more likely to vote, and so to make his opinion count. Unfortunately, television's influence has been greatly harmful to the young. Children do not have enough experience to realize that TV shows present an unreal world; that TV advertisements lie to sell products that are sometimes bad or useless. They believe and want to practise what they see. They do believe that the violence they see is normal and acceptable. All educators agree that the "television generations" are more violent than their parents and grandparents. Also, the young are more impatient. Used to TV shows, where everything is quick and interesting, they do not have the patience to read an article without pictures, to read a book that requires thinking, to listen to a teacher who doesn't do funny things like the people on children's pro- grams. And they expect all problems to be solved happily in ten, fifteen, or thirty minutes. That's the time it takes on the screen.
