13、etle, which can chew its way past the plants defense system by cutting the main vein that delivers the poison to the leaves. This vein cutting is jut one method the beetles used to prepare a safe meal. Then they simply eat between the veins of poison. In the past, scientists who studied insect adapt

14、ation to plant defenses have focused on chemical responses. It is only after a beetle has survived several encounters with the plants resin that it learns how to avoid the poison by chewing through the resin transporting veins on the next leaf it eats and thus gives itself a meal. However, it can ta

15、ke a beetle an hour and a half of careful vein cutting to prepare a small leaf that takes it only a few minutes to eat. So, though the method is effective, its not very efficient. 2.

The man did everything he could to teach the parrot to say Ketunnel, but he never succeeded. At first he was

26、 very gentle with the bird. But gradually, he lost his temper. You stupid bird. Why cant you learn to say that one word? Say Ketunnel or I will kill you. But the parrot would not say it. Many times the man screamed, Say Ketunel, or Ill kill you. But the bird would never repeat the name. Finally, the

31、h for the road was extremely difficult to clear.D.Hostilities between Canada and the United States caused construction delays.答案:B解析 17-20 The Old Canada Road is a long lost trail between the Canadian province of Quebec and Maine in the northeast corner of the United States. Yes, it really was lost

32、and finding it again was a complex process that involved advanced technology: how the location of the roads was pinpointed was very interesting. And Ill return to it as soon as I gave you a little background information. The road was begun in 1817, a few years before Maine even became a state. At th

33、e time Quebec was a major market for livestock, crops and fish. So a road to Quebec was seen by officials in Maine as necessary for trade. For about 20 years the movement of people and goods was mostly from Maine to Quebec, and then the trend reversed as thousands of Canadians immigrated to Maine to

34、 escape poor crops, the lack of jobs and the threat of disease. I think it was a color epidemic. Besides its negative reasons major building projects in Maine also made the state very attractive for the Canadians who needed work. I should stress though that immigration during that period went in bot

35、h directions. In fact the flow of people and goods went completely unhindered. There wasnt even a border post until around 1850. The people of the time saw Maine and Quebec as a single region mainly because of the strong French influence which is still evident in Maine today. Eventually the road fel

36、l into disuse as a major railway was completed. Finally people simply forgot about it and thats how it came to be lost. This brings me back to the original topic. 8.

37、 had better employment opportunities.C.Maine was politically stable.D.Marine had a better climate.答案:B9. What can be inferred about the region including Maine and Quebec during the early 1800s?A.The area was economically unified.B.The authorities were unable to enforce law and order.C.The two govern

38、ments fought for control of the area.D.Most of the people living there spoke only French.答案:A10. What subject is the speaker most likely to discuss next?A.The latest practices of accurate mapmaking.B.The impact of epidemics on mass migration.C.The advantages of establishing international trade agree

39、ments.D.The technology used to locate the Old Canada Road.答案:DSection Use of English Read the following text. Choose the best word for each numbered blank and mark A, B, C or D on ANSWER SHEET 1. Boeing Cos Sonic Cruiser, a proposed faster airliner, would be mostly blended material, program director

40、 Walt Gillette said recently.

Why does the author mention Continental Illinois Bank 答案:DPassage 2 Beads were p

51、robably the first durable ornaments humans possessed, and the intimate relationship they had with their owners is reflected in the fact that beads are among the most common items found in ancient archaeological sites. In the past, as today, men, women, and children adorned themselves with beads. In

52、some cultures still, certain beads are often worn from birth until death, and then are buried with their owners for the afterlife. Abrasion due to daily wear alters the surface features of beads, and if they are buried for long, the effects of corrosion can further change their appearance. Thus, int

53、erest is imparted to the bead both by use and the effects of time. Besides their wearability, either as jewelry or incorporated into articles of attire, beads possess the desirable characteristics of every collectible. They are durable, portable, available in infinite variety, and often valuable in

54、their original cultural context as well as in todays market. Pleasing to look at and touch, beads come in shapes, colors, and materials that almost compel one to handle them and to sort them. Beads are miniature bundles of secrets waiting to be revealed: their history, manufacture, cultural context,

55、 economic role, and ornamental use are all points of information one hopes to unravel. Even the most mundane beads may have traveled great distances and been exposed to many human experiences. The bead researcher must gather information from many diverse fields. In addition to having to be a general

56、ist while specializing in what may seem to be a narrow field, the researcher is faced with the problem of primary materials that have little or no documentation. Many ancient beads that are of ethnographic interest have often been separated from their original cultural context. The special attractions of beads contribute to the uniqueness of bead research. While often regarded as the small change of civilizations, beads are a part of every culture, and they can often be used
