According to the report by Baekeland and Hartmann, two American authoritative psychotogical research centres, the "short sleepers" had been more or less average in their sleep needs until the men were in their teens．But at about age 15 or so, the men voluntarily began cutting down their nightly sleep time because of pressures from school, work and other activities. These men tended to view their nightly per
iods of unconsciousness as bothersome interruptions, in their daily routines.
In general, these "short sleeps" appeared ambitious, active, energetic, cheerful,, conformist （循规蹈矩的） in their opinions, and very sure about their career choices．They often held several jobs at once, or workers full - or part - time while going to school．And many of them had a strong urge to appear "normal" or "acceptable" to their friends and associates．When asked to recall their dreams, the "short sleepers" did poorly．More than this, they seemed to prefer not remembering．In similar fashion, their usual way of dealing with psychological problems was to deny that the problem existed, and then to keep busy m the hope that the trouble would go away．The sleep patterns of the “short sleepers" were similar to, but less extreme than, sleep patterns shown by many mental patients categorized as manic （疯人）.
The "long sleepers" were quite different indeed．Baekeland and Hartmann report that these young men had been lengthy sleeps since childhood．They seemed to enjoy their sleep, protected it, and were quite concerned when they were occasionally deprived （剥夺） of their desired 9 hours of nightly bed rest．They tended to recall their dreams much better than the "short sleepers．" did．Many of the "long sleepers" were shy, anxious, introverted （内向）, inhibited （压抑） , passive, mildly depressed, and unsure of themselves （particularly in social situations）．Several openly states that sleep was an escape from their daily problems．

My Uncle Dave posed an interesting question to my wife and me when he came to visit us the other day. He asked: “What do you think the world will be like in 50 or 100 years, in terms of technology and society and so on?”
He says he asks many of the people he meets this question to see what their thoughts are. His point is that no one really knows. I mean, in 1945, could people have even imagined surfing the net or sending e-mails as we do? No way. And the pace of technological innovation(创新) is incredible (难以置信的). We’re on a more different curve than we used to be.
One thing I’m looking forward to is real software agents. There is so much information out there, but I want something that can help me find what I really want. For instance, in about ten years, I think, there will be no longer recorded music, and there will be some big databases from which you can download music onto your hard drive or whatever. At that point, there will be so much music to choose from and you’ll be able to sample things before you buy them. But the question will be how I find what I’m looking for and how I do find the music that might interest me. Or more generally, how do I find information that I want without spending all the time myself surfing the net? How do I find people who are like-minded (具有相似目的), with whom I might really want to communicate? I want to find those people but it’s hard to do. In the future I think that one will be able to build a community of like-minded people who live all over the globe. It’s going to be very interesting, I think.No one really knows what the future will be like because _____.

Environmental health is defined as the control of the factors (因素) in the environment that may have harmful effects on people’s physical, mental, or social well-being (安乐). Because natural disasters expose people to danger by bringing up or threatening their immediate environment, effective management of environmental health after a natural disaster is of great importance.
The environmental health measures that must be considered after a natural disaster include the supply of appropriate shelter for individuals or groups of people left homeless, the distribution (分配) of safe and accessible water, and the protection and distribution of safe food products and so on.
To effectively manage environmental health during and after a disaster, it is important that a state of preparation is in effect before the event actually occurs. During an emergency, success largely depends on making good, rapid judgment and appropriate response measures. High-level decision makers, therefore, must be familiar with sound measures beforehand and should be given an accurate judgment of the disaster’s specific effects as quickly as possible.
This book is intended to serve as a guide for those who may be called upon to make emergency decisions after disaster strikes. The recommended environmental health measures have been listed in the order of priority in which they should be taken during an emergency. However, each natural disaster is unique in the degree or type of emergency. In response to any given disaster, decision makers may find it necessary to change the priority assigned to any particular measure. The first paragraph is mainly to _____.
| A．tell the reader how to understand environmental health |
| B．express why environmental health after a natural disaster is important |
| C．describe the terrible scene that is caused by the natural disasters |
| D．give advice on how to deal with the management of environmental health |
In order to effectively cope with the emergency, the most important is that _____.
| A．we should have enough shelters and tools |
| B．everyone should be familiar with the situation |
| C．we should be well prepared for it in advance |
| D．we can deal with it just as we did before |
We can’t do just as the recommended environmental health measures because _____.
| A．some of the measures have not been taken before |
| B．they are not the same according to different degrees or types of emergency |
| C．they are probably made up by someone without experience |
| D．they can’t be changed once they are taken by the experts |
The best title of this passage should be _____.
| A．Environmental Health Management after Natural Disasters |
| B．The Bad Influence of the Natural Disasters |
| C．Useful Measures to Avoid the Natural Disasters |
| D．The Importance of the Environmental Health Management |
On April 10, 1815, Mount Tambora in Indonesia erupted with great force. Fifty cubic kilometers of magma (岩浆) flew from its peak (山顶) and a blanket of ash as thick as one centimeter fell over more than 500,000 square kilometers of Indonesia and the Java Sea. The eruption destroyed Tambora’s peak and formed a hole six by seven kilometers wide. The eruption and resulting tsunamis killed 10,000 people. The agricultural loss and disease brought about by the thick ash caused the deaths of 82,000 more.
Indonesia was rocked again in 1883. On August 26, a small volcano on an uninhabited island between Sumatra and Java, erupted. The eruption produced an ash cloud 80 kilometers high and was heard in Australia—4,800 kilometers away. The eruption also caused a tsunami, which pounded (击打) the shores of Java and Sumatra—killing 36,000 people.
In 1902, St. Pierre was a thriving (兴盛的) community and the largest town on the French colony of Martinique in the Caribbean Sea. Mont Pelee cast a shadow over the town from where it stood, eight kilometers to the north. The townspeople were used to the light continuous sounds of the mountain, but in May, 1902 Pelee started to get really unstable. Clouds of steam and ash poured from the volcano and on May 8, Pelee erupted. Superheated gas and steaming volcanic ash flew out, pouring down the mountain at high speed. Within seconds, the deadly gas cloud had destroyed the town of St. Pierre and incinerated everyone in it — except one prisoner in a basement cell. It was the worst volcano disaster of the 20th century. How many people died because of the eruption on April 10, 1815 ?
| A．About 10,000. | B．More than 82,000. |

In the Middle Ages in Europe, theater was an important part of civic, economic and religious life. During this period after the fall of Roman civilization, many cities were destroyed. Southern and Western Europe, famous for its agriculture, became increasingly more agricultural. After several hundred years, many towns appeared again. The Roman Catholic Church took over religion, education and politics. What remained of theater was mostly on the Greek and Roman performing arts.
Theater was reborn as liturgical(礼拜式的) dramas. It was written in Latin and dealing with biblical(圣经) stories which would be performed by church members. Then there came local dramas spoken in common language not Latin. They were more wonderful one-act dramas taking place in town squares or other parts of the city. There were three types of local dramas. Mystery or cycle plays were short dramas based on biblical stories organized into historical cycles. Miracle plays dealt with the lives of the great. Morality(道德的) plays taught a lesson through characters standing for good or bad qualities. Secular plays in this period existed, but religious drama in the Middle Ages is mostly remembered today.

Health and climate scientists have mapped how climate change affects different parts of the world in different ways. The scientists point to the fact that changes in the past thirty years may, have been affecting human health. Possible effects include more deaths from extreme(极度的) heat or cold, more storms and more crop failures in dry periods.
The health and climate scientists recently estimated(估计) that climate changes caused by human activity lead to more than one hundred and fifty thousand deaths each year. Cases of sickness are estimated at five million. And the W.H.O. says the numbers could rise quickly by the year of 2003.
Jonathan Patz of an environmental institute led the study. Professor Patz points out that climate scientists connected global warming with the heat that killed thousands in Europe in August, 2003. But he says poor countries least responsible(对……负责) for the warming are most in danger from the health effects of higher temperatures.
Professor Patz says areas in greatest danger include southern and eastern Africa and coastlines along the Pacific and Indian oceans. Also, large cities experience what scientists call a "heat island"effect that can make conditions worse.
Representatives(代表) from about two hundred countries hold a meeting in Canada, to discuss climate change. The ten-day meeting ends on December 9th. It is the first such United Nations meeting since the Kyoto Protocol(京都议定书) took effect earlier this year. The agreement aims to reduce the amount of carbon dioxide(二氧化碳) and other heat-trapping(吸热的) gases sent off into the air.Who is Jonathan Patz?
| A．A scientist responsible for the climate change. |
| B．A scientist in charge of the study of the climate change. |
| C．A professor interested in the climate change. |
| D．A professor who is a representative from an African country. |
Which of the following statements is TRUE according to the passage?
| A．Climate changes affect different parts of the world in the same way. |
| B．The ten-day meeting is the first United Nations meeting on climate change. |
| C．The Kyoto Protocol aims to make smaller the amount of heat-trapping gases into the air. |
| D．Poor countries are responsible for the global warming. |
Possible effects from the climate changes include the following EXCEPT ______.
| A．crop failures | B．storms | C．more deaths from overheat | D．air pollution |
According to the health and climate scientists, climate changes have been caused by ______.
| A．dry weather | B．cold weather | C．human activities | D．storms |
We can infer from the passage that ______.
| A．climate changes are having a bad effect on human’s health |
| B．Professor Patz leads the study of climate changes |
| C．a "heat island"effect large cities experience makes the matter worse |
| D．rich countries are most responsible for climate changes |
