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 Every time I visit her, I notice how many new things there are in her house, and how many things lie unused, out of date.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（）.
