选出应填入下面一段英语中______内的正确答案。
One of the difficulties in building an SQL-like query language for the Web is the absence of a database(1)for this huge, heterogeneous repository ofinformation. However, if we are interested in HTML documents only, we can construct a virtual schema from the implicit structure ofthese files. Thus, at the highest level of(2), every such document is identified by its Uniform Resource Locator (URL), a(3)and a text. Also, Web servers provide some additional information such as the type, length, and the last modification date of a document. So, for data mining purposes, we can consider the set of all HTML documents as a relation:
Document (url, title, text,type, length, modify)
Where all the(4)are character strings. In this framework, an individual document is identified with a(5)in this relation. Ofcourse, if some optional information is missing from the HTML document, the associate fields will be left blank, but this is not uncommon in any database.

M: Sure, Mary. I've summarized the results in the handout, broken down by consumer age groups and sporting activities. The survey was administered to 550 men and women between the ages of 18 and 55 years old, and the results have been compiled in the following age groups: 18 to 26, 27 to 35, 36 to 45, and 46 to 55. According to the results, the most active group involved in spotting activities are those between 18 and 26 years old, followed by those 36 to 45 years old.
W: Okay.
M: As fur as particular sports are concerned, people in these two groups cited jogging as their favorite recreational sport followed by skiing, tennis, swimming, and cycling.
W: Hmm. Based on what you have said, I think we should consider targeting the 18 to 26-yeur-old-age group more in the future. I also feel we should consider expanding our line of athletic shoes, particularly jogging and tennis footware. We also have to come up with a more appealing slogan aimed at this age group.
M: I see what you mean. However, when these results are compared with the survey carried out three years ago, we can see a growing trend among older consumers. I believe this trend will continue, so we should focus on this group instead.
W: I see your point. Well, let's meet again on Wednesday to iron out more of the details of this proposal.
What is the result of the survey on leisure sporting activities used for？
A．For Friday's business meeting.
B．For the plan.
C．For their new products.
D．For a new proposal.

"Psychological, social and cultural studies pertaining to virtually everything that people treat as a problem in our civilization," the committee writes, "play a large role. "Paradoxically, one would think these would be times when social science research would be riding high. Yet even though governments are more than alarmed about a variety of social problems, they are inclined to deal with them by trial and (often) error. The abuse of drugs is a widely-spread concern, but governments seem to concern themselves with the qualifications of teachers and their salaries.
If we lack an adequate understanding of drug abuse and educational processes, are we flying blind attempting to deal with these behaviors.？ What domains of your life could benefit from social and behavioral science research？ For instance, are we concerned about crime？ Consider that recent sociological research reveals that nearly half of all urban dwelling American males can expect to be arrested for some non-traffic offense during their lives. However, a very small group of career predators are responsible for a grossly disproportionate share of all crimes committed. What does this in sight suggest to you about American criminal justice and prison policies？ Sociological work also shows that most criminals halt their careers by age 25 to 30. Does this finding have policy implication？ If a 29-year-old burglar whose criminal career is nearly over is imprisoned for ten years, may many years of that imprisonment be wasted on expensive and unnecessary confinement？
According to the author, social and behavioral sciences are losing federal financial support chiefly because some people ______.
A．don't see the seriousness of the present situation
B．don't quite see the use for these sciences
C．only consider natural sciences as true sciences
D．are unable to solve social problems with them

听力原文： At a certain time in our lives we consider every place as the possible sites for a house. I have thus searched the country within a dozen miles of where I live. In imagination I have bought all the farms, one after another, and I knew their prices.
The nearest thing that I came to actual ownership was when I bought the Hollowell place. But before the owner completed the sale with me, his wife changed her mind and wished to keep it, and he offered me additional dollars to return the farm to him. However, I let him keep the additional dollars and sold him the farm for just what I gave for it.
The real attraction of the Hollowell farm to me was its position, being about two miles from the village, half a mile from the nearest neighbor, bounded on one side by the river, and separated from the highway by a wide field. The poor condition of the house and fences showed that it hadn't been used for some time. I remembered from my earliest trip up the river that the house used to be hidden behind a forest area, and I was in a hurry to buy it before the owner finished getting out some rocks, cutting down the apple trees, and clearing away some young trees which had grown up in the fields. I wanted to buy it before he made any more of his improvements. But it turned out as I have said.
I was not really troubled by the loss. I had always had a garden, but I don't think I was ready for a large farm. I believe that as long as possible it is better to live free and uncommitted. It makes but little difference whether you own a farm or not.
Questions 26 to 29 are based on the passage you have just heard.
26. What do we know about the speaker？
27. Why did the speaker decide to buy the Hollowell place？
28. Why did the speaker want to buy the farm in a hurry？
29. What does the speaker believe as important in life？
(33)
A．He made money by buying and selling farms.
B．He made a study of many farms before buying.
C．He had the money to buy the best farm in the country.
D．He wanted to buy the oldest farm near where he lived.

Memory can be defined as the capacity to keep【B4】available for later use. It includes not only "remembering" thing like arithmetic or historical facts, but also any change in the way an animal typically behaves. Memory is【B5】when a rat gives up eating grain because he has sniffed something suspicious in the grain pile. Memory is also involved when a six year old child learns to swing a baseball bat.
Memory【B6】not only in humans and animals but also in some physical objects and machines. Computers, for example, contain devices for storing data for later use. It is interesting to compare the memory storage capacity of a computer【B7】that of a human being. The instant access memory of a large computer may hold up to 100 000 "words" ready for【B8】use. An average American teenager probably recognizes the meanings of about 100 000 words of English. However, this is but a fraction of the total【B9】of information which the teenager has stored. Consider, for example, the number of facts and places that the teenager can recognize on sight. The use of words is the basis of the advanced problem solving intelligence of human beings. A large part of a person's memory is in terms of words and【B10】of words.
【B1】
A．of
B．to
C．for
D．on

Consider medicine, for instance. No one can deny that medical progress has enriched our lives tremendously. Because of medical advances, we eat better, live easier and are able to take care of ourselves more efficiently. We can cure disease with no more than one injection or a pill. If we have a serious accident, surgeons can put us back together again. If we are born with something defective, they can repair it. They can make us happy, restore our normality, ease our pain, replace worn parts and give us children. They can even bring us back from the dead. These are wonderful achievements, but there is a price we have to pay.
Because medicine has reduced infant mortality and natural death so significantly, the population has been rising steadily, in spite of serious efforts to reduce the rate of population growth. Less than a century ago in the United Stales, infant mortality claimed more than half of the newborn within the first year of life. Medical advances, however, have now reduced that rate to nearly zero. A child born in the United States today has better than a 90% chance of survival. Furthermore, medical advances have ensured that most of these infants will live to be seventy years of age or more, and even that life expectancy increases every year. The result of this progress is an enormous population increase that threatens the quality of life, brought about by progress in the medical profession.
According to this passage, " progress" doesn't always mean that______.
A．something has become stronger and better
B．something has been changed from being one thing to another
C．something has become funny
D．something turns out to be worse than before
