疲劳是人们向医生、朋友和亲人最常抱怨的问题之一。或许你认为在这个拥有各种节省体力的装置和方便的交通设施的时代。很少有人会有理由感到如此疲劳。然而，今天与用手捆干草，用搓衣板洗衣服的昔日相比，抱怨疲劳的人也许更多了。据医生们说，疲倦更可能是由于过少的活动所致，而不是过多的活动所引起的。情绪问题和烦恼，特别是忧郁和焦虑，显然是长期疲劳最常见的原因。

Read the following passage carefully and then translate the underlined sentences into Chinese.My eldest daughter, an Internet consultant, is only 30, but she has already lived in five different houses in five different places and has had about six different jobs. Every time I visit her, I notice how many new things there are in her house, and how many things lie unused, out of date. What is even more striking is how many things there are which are not expected to last—disposable things. Disposable plates and glasses, disposable towels and babies, nappies (尿布). It sometimes seems that we live in an age of the disposable. （1）This phenomenon of constant change runs through everything in life nowadays, from fashion to music, from medicine to motorcars, from education to employment. Two important factors seem to be driving these changes. The first is the rapid growth in knowledge and the consequent rapid development of technology. The second is the revolution in communications, which means that knowledge is spread faster and more widely than ever. Our times are often called “the information age” and the effect is to bring about “the knowledge economy”. New technologies and new knowledge bring about the need for new skills.（2） The speed with which these technologies are being created is such that all of us are faced with the challenge of learning new skills, not just once, but several times. What we knew yesterday is often obsolete today.I remember my daughter saying to that she was at “the cutting edge” of her particular field. But within five years, she said, she would have to do something new and different to keep up. There is a great need for flexibility and problem-solving than before. Tasks require a greater integration of skills. （3）The rewards of life go to the multi-skilled, to flexible teams of workers each capable of contributing in a range of ways. （4）To succeed in this new world of work, individuals will have to regard their careers not just as a process of gathering experience, but as a process of learning new things on an almost continuous basis. All this suggests to me that the relationship between education and employment has changed radically over the last few years. （5）One could summarize the change by saying that when I learned things in order to achieve life-long employment while my children need to pursue life-long learning in order to stay employed.

Humans are forever forgetting that they can't control nature. Exactly 20 years ago, a Time magazine cover story announced that “scientists are on the verge of being able to predict the time, place and even the size of earthquakes”. The people of quake-ruined Kobe (神户) learned last week how wrong that assertion was.None of the methods praised two decades ago have succeeded. Even now, scientists have yet to discover a uniform warning signal that precedes all quakes, let alone any sign that would tell whether the coming quake is mild or a killer. Earthquake formation can be triggered by many factors, says Hiroo Kanamori, a seismologist at the California Institute of Technology. So finding one all-purpose warning sigh is impossible. One reason: quakes start deep in the earth, so scientists can't study them directly.If a quake precursor were found, it would still be impossible to warn humans in advance of all dangerous quakes. Places like Japan and California are filled with hundreds, if not thousands, of minor faults. It is impossible to place monitoring instruments on all of them. And these inconspicuous sites can be just as deadly as their better-known cousins like the San Andreas (圣安得列斯断层).Both the Kobe and the 1994 Northridge quakes occurred on small faults.Prediction would be less important if scientists could easily build structures to withstand tremors. While seismic engineering has improved dramatically in the past 10 to 15 years, every new quake reveals unexpected weaknesses in “quake-resistant” structures, says Terry Tullis, a geophysicist at Brown University. In Kobe, for example, a highway that opened only last year was damaged.In the Northridge earthquake, on the other hand, well-built structures generally did not collapse. But engineers have since found hidden problems in 120 steel-frame buildings that survived. Such structures are supposed to sway with the earth rather than crumple. They may have swayed but the quake also unexpectedly weakened the joints in their steel skeletons. If the shaking had been longer or stronger, the buildings might have collapsed.A recent report in Science adds yet more anxiety about life on the fault lines. Researchers can computer simulations to see how quake-resistant buildings would fare in a moderate-size tremor, taking into account that much of a quake's energy travels in a large “pulse” of focused shaking. The results: both steel-frame buildings and buildings that sit on insulating rubber pads suffered severe damage.More research will help experts design stronger structures and possibly find quake precursors. But it is still a certainty that the next earth will prove once again that every fault cannot be monitored and every highway cannot be completely quake-proofed.1.Which of the following statements is true about Kobe?2.The author's focus in Para. 3 is on （）.3.It's impossible to avoid damages in earthquakes because （）. 4.It is implied in the passage that （）. 5.The best title for this passage could be（）.

What exactly is a lie? Is it anything we say which we know is untrue? Or is it something more than that? For example, suppose a friend wants to borrow some money from you. You say, "I wish I could help you but I'm short of money myself." In fact, you are not short of money but your friend is in the habit of not paying his debts and you don't want to hurt his feelings by reminding him of this. Is this really a lie?Professor Jereald Jellison of the University of Southern California has made a scientific study of lying. According to him, women are better liars than men, particularly when telling a "white lie", such as when a woman at a party tells another woman that she likes her dress when she really thinks it looks awful. However, this is only one side of the story. Other researchers say that men are more likely to tell more serious lies, such as making a promise which they have no intention of fulfilling. This is the kind of lie politicians and businessmen are supposed to be particularly skilled at: the lie from which the liar hopes to profit or gain in some way.Research has also been done into the way of people's behavior changes in a number of small, apparently unimportant ways when they lie. It has been found that if they are sitting down at the time, they tend to move about in their chairs more than usual. To the trained observer they are saying “I wish I were somewhere else now”. They also tend to touch certain parts of the face more often, in particular the nose. One explanation of this may be that lying causes a slight increase in blood pressure. The tip of the nose is very sensitive to such changes and the increased pressure makes it itch（痒）.Another gesture which gives liars away is what the writer Desmond Morris in his book ManWatching calls “the mouth cover”. He says there are several typical forms of this, such as covering part of the mouth with fingers, touching the upper-lip or putting a finger of the hand at one side of the mouth. Such a gesture can be interpreted as an unconscious attempt on the part of the liar to stop himself or herself from lying.Of course, such gestures as rubbing the nose or covering the mouth, or moving about in a chair cannot be taken as proof that the speaker is lying. They simply tend to occur more frequently in this situation. It is not one gesture alone that gives the liar away but a whole number of things, and, in particular, the context in which the lie is told.1.One sometimes tells one's friend a “white lie” because one wants to （）. 2.One research suggests that women （）.3.It can be inferred from the passage that （）. 4.People may rub their noses when they lie because （）. 5.It can be learned from the passage that（）.

While there is little systematic work relating foreign language learning strategies to success, there are a number of observations which can be made about individuals who are good language learners.I have been able to isolate some of the individuals by observing students in classrooms in California and Hawaii, by observing myself and talking to other good language learners, by eliciting observations from some second language teachers. As I have begun to observe classes, what fascinates me is how often the teacher plows ahead with the lesson seemingly with little awareness of what is going on in each student, and often without directing the attention of the poorer students to how the successful student arrived at his answer. That is, many foreign language teachers are concerned with finding the best method or with getting the correct answer, yet the teachers fail to attend to the learning process. If they attended to it more, they might be able to tailor their input to their students' needs and might be able to provide their students with techniques that would enable them to learn on their own. Indeed, no course could ever teach all we need to know about a language, and the students must find the means to help themselves, when the teacher is not around.The task of observing these strategies is a complicated one because the strategies necessarily involve cognitive processes which neither the learner nor the teacher may be able to specify. However, when our attention is focused on observing these strategies, I think we may find it easier to isolate some of them. Just recently, I discovered that by using video tapes we hope to help learners and teachers see what is going on in the classroom. We hope to be able, as well, to abstract the learner strategies by interviewing the learner about his behavior during a particular classroom which showing them a tape of their own behavior.In spite of the fact that we are only beginning to isolate these strategies, I think that it is useful to list some of the ones found thus far. They remain general but give an idea of the kind of strategies I think we ought to be looking for.1.Which of the following could be the best title for this passage?2.The author formed some ideas about the features of good foreign language learning by getting information from （）.3.The author believes that the most important task of a good language teacher is （）. 4. “They might be able to tailor their input to their students' needs” means （）. 5.Observing language learning strategies is very complicated because（）.

In a theoretical model of decision making, a decision is defined as the process of selecting one option from among a group of options for implementation. Decisions are formed by a decision maker, the one who actually chooses the final option, in conjunction with a decision unit, all of those in the organization around the decision maker who take part in the process. In this theoretical model, the members of the decision unit react to an unidentified problem by studying the problem, determining the objectives of the organization, formulating options, evaluating the strengths and weaknesses of each of the decision, including the nature of the problem itself, external forces exerting an influence on the organization, the internal dynamics of the decision unit, and the personality of the decision maker. Additionally, when a decision must be made in a crisis situation, both stress and the speed at which events are progressing can have an effect, often a negative one, on the decision process.During recent years, decision making has been studied systematically by drawing from such diverse areas of study as psychology, sociology, business, government, history, mathematics, and statistics. Analyses of decisions often emphasize one of three principal conceptual perspectives (though often the approach that is actually employed is somewhat eclectic).In the oldest of the three approaches, decisions are made by a rational actor, who makes a particular decision directly and purposefully, in response to a specific threat from the external environment. It is assumed that this rational actor has clear objectives in mind, develops numerous reasonable options, considers the advantages and disadvantages of each option carefully, chooses the best option after careful analysis, and then proceeds to implement it fully. A variation of the rational actor model is decision maker who is satisfier, one who selects the first satisfactory option rather than continuing the decision making process until the optimal decision has been reached.1.It can be inferred from the information in paragraph 1 that the theoretical decision making process （）.2.The phrase “in conjunction with” in paragraph 1 could best be replaced by （）. 3.All of the following are listed in paragraph 1 as having an effect on decisions EXCEPT （）. 4.It can be inferred from paragraph 3 that rational actor would be least likely to （）. 5.The word “it” in line 5, Paragraph 3 refers to（）.

In colonial America, people generally covered their beds with decorative quilts resembling those of the lands from which the quitters had come. Wealthy and socially prominent settlers made quilts of the English type, cut from large lengths of cloth of the same color and texture rather than stitched together from smaller pieces. They made these until the advent of the Revolutionary War in 1775, when everything English came to be frowned upon.Among the whole-cloth quilts made by these wealthy settlers during the early period are those now called linsey-woolseys. This term was usually applied to a fabric of wool and linen used in heavy clothing and quilted petticoats worn in the wintertime. Despite the name, linsey-woolsey bedcovers did not often contain linen. Rather, they were made of a top layer of woolen or glazed worsted wool fabric, consisting of smooth, compact yarn from long wool fiber dyed dark blue, green, or brown with a bottom layer of a coarser woolen material, either natural or a shade of yellow. The filling was a soft layer of wool which had been cleaned and separated and the three layers were held together with decorative stitching done with homespun linen thread. Later, cotton thread was used for this purpose. The design of the stitching was often a simple one composed of interlocking circles or crossed diagonal lines giving a diamond pattern.This type of heavy, warm, quilted bedcover was so large that it hung to the floor. The comers are cut out at the foot of the cover so that the quilt fit snugly around the tall four-poster, beds of the 1700s, which differed from those of today in that they were shorter and wider; they were short because people slept in a semi-sitting position with many bolsters or pillows, and wide, because each bed often slept three or more. The linsey-woolsey covering was found in the colder regions of the country because of the warmth it afforded. There was no central heating and most bedrooms did not have fireplaces.1.What does this passage mainly discuss?2.The author mentions the Revolutionary War as a time period when （）.3.The quilts described in the second and third paragraphs were made primarily of（）. 4.It can be inferred from the third paragraph that the sleeping habits of most Americans have changed since the 1700s in all the following ways EXCEPT （）. 5.Which of the following was most likely to be found in a bedroom in the colder areas of the American colonies?
