听力原文:Recent films, books, magazines and newspapers have reported about serious threats

听力原文: Recent films, books, magazines and newspapers have reported about serious threats to the environment. Changes in climate, increasing pollution, rising energy demands, and decreasing supplies of water are worldwide problems. Designers and builders around the world are reacting to these environmental concerns with new conception of green house.

Green houses are designed to be sustainable. Something that is sustainable provides people today with what they need. But it does not use up or damage the natural resources.

Green houses use much less fossil fuels—oil, gas and coal—for energy. The houses are placed on the land so the sun warms them during cold months and is blocked during hot months. The houses have plenty of windows that open to let in cooling air. They have special equipment that uses a lot less water.

Green houses are made of wood from fast-growing trees so old growth forests do not have to be cut. They include recycled materials so something old is re-used, not thrown away as waste. The houses are healthier for people to live in. Materials used in them are not processed with strong chemicals that can produce harmful gases.

Houses that are environmentally friendly are not new. For years, architects in many areas of the world have designed and built them for environmental activists. But now, rapidly rising energy costs are increasing the demand worldwide for green houses that use less energy and other resources.

(33)

A.It is a new design to keep people warm in winter.

B.It is closely sea!0d so that cool air cannot go through.

C.It is a new design without exhausting or harming natural resources.

D.It is created for gardening or fanning.

听力原文: A recent report has shown that in the United States, people have experienced an evolution concerning their attitudes towards the workweek and weekend. Although some calendars still mark the beginning of a week as Sunday, more and more of Americans are coming to regard Monday as the first day of the week with Saturday and Sunday comprising the two-day period thought of as the weekend. In fact, the word "weekend" didn't even exist in English until about the middle of the last century. In England at that time, Saturday afternoons had just been added to Sundays and holidays as a time for workers to have off from their jobs. This innovation became common in the United States in the 1920s, but as the workweek shortened during the Great Depression of the 1930s, the weekend expanded to two full days—Saturday and Sunday. Some people thought that this trend would continue due to increasing automation and the workweek might decrease to four days or even fewer. But so far this hasn't happened. The workweek seems to have stabilized as forty hours made up of five eight-hour days. And nowadays the idea of adding Monday to the weekend has also been proposed by some people.

(30)

A.Shifting job opportunities.

B.The evolution of the weekend.

C.Attitudes toward employment,

D.Attitudes toward leisure activities.

听力原文:M: Hello. This is Greg Rice reporting live in Barrow, Alaska.

W: Hello, Greg. Is everything going smoothly?

M: Yes. I've just arrived here in Barrow, Alaska, to bring you live coverage of what appears to be the results of a huge meteorite impact, perhaps the largest in recent history, that occurred just twelve hours ago. The exact location of the impact is unknown, but estimates put it about 20 kilometers south of Barrow based on shock waves felt throughout the region.

W: Are there any witnesses?

M: Yeah. Some witnesses say they saw a bright light streaking through the sky, accompanied by a roaring boom, moments before the impact. It's unknown whether there are any casualties, but it is unlikely considering this sparsely populated area.

W: It's said that such impacts were commonplace during the formation of our solar system, and many believe that a meteorite 10 kilometers in diameter which crashed into Earth 65 million years ago led to the mass extinction of many animal species including the dinosaurs.

M: You're right. But it is often difficult to calculate the number of such large impacts on Earth because erosion and vegetation make it difficult to spot them. In recent years, astronomers have focused more of their attention on the paths of many uncharted space rocks or asteroids floating out there in the hope that we might be able to determine the threat they pose on mankind...This is Greg Rice reporting from Alaska.

W: Thanks, Greg...We'll keep you up-to-date on any development there.

(23)

A.An alien spacecraft landing.

B.The impact of a meteorite.

C.A volcanic eruption.

D.The blizzard conditions in Alaska.

听力原文:This is Ray McCarthy with the news. Reports are coming in of a major train crash

听力原文: This is Ray McCarthy with the news. Reports are coming in of a major train crash in Japan. (32) A passenger train carrying hundreds of workers home from the center of Tokyo is reported to have hit an oncoming goods train. Both were traveling at high speed. (33) Figures are not yet available but it is believed that the death toll could be as high as 300, with hundreds more injured. Emergency and rescue services rushed to the scene. But our reporter says it will take days to clear the track and to establish the numbers of the dead and injured. There was a similar accident on the same stretch of track four years ago.

(34) There was another bomb scare in a large London store last night during late night shopping. Following a telephone call to the police from an anonymous caller, hundreds of shoppers were shepherded out of the store while roads in the area were sealed off. Police dogs spent hours searching the store for a bag which the caller claimed contained 50 pounds of explosives. Nothing was found and the store was given the all-clear by opening time this morning. A police spokesman said that this was the third bomb scare within a week and that we should all be on our guard.

And finally, the motoring organizations have issued a warning to drivers following the recent falls of snow in many parts of the country. (35) Although the falls may be slight, they say extra care is needed.

Questions:

What accident happened recently in Japan?

What do the reports say about the recent accident in Japan?

Why did people have to leave the London store last night?

What did motoring organizations advise drivers to do?

(33)

A.A goods train hit a bus carrying many passengers.

We all know that the normal human daily cycle of activity is of some 7-8 hours' sleep alte
rnating with some 16 to 17 hours' wakefulness and that, broadly speaking, the sleep normally coincides with the hours of darkness. Our present concern is with how easily and to what extent this cycle can be modified.

The question is not mere academic one. The case, for example, with which people can change from working in the day to working at night is a question of growing importance in industry where automation calls insistently for round-the-clock working of machines. It normally takes from five days to one week for a person to adapt to reversed routine of sleep and wakefulness, sleeping during the day and working at night. Unfortunately, it is often the ease in industry tint shifts are changed every week; a person may work from 12 midnight to 8 a.m. one week, 8 a.m. to 4 p.m. the next, and 4 p.m. to 12 midnight the third and so on. This means that no sooner has he got used to one routine than he has to change to another, so that much of his time is spent neither working nor sleeping very efficiently.

One answer would seem to be longer periods on each shift, a month, or even three months. Recent research by Bonjer of the Netherlands, however, has shown that people on such systems will revert to their normal habits of sleep and wakefulness during the weekend and that this is quite enough to destroy any adaptation to night work built up during the week.

The only real solution appears to be to hand over the night shift to a corps of permanent night workers whose nocturnal wakefulness may persist through all weekends and holidays. An interesting study of the domestic life and health of night-shift workers was carried out by Brown. She found a high incidence of disturbed sleep, digestive discord and domestic disruption among those on alternating day and night shifts, but no abnormal occurrence of these symptoms among those on permanent night work.

The article is mainly about ______.

A.how the normal human daily cycle works

B.how to deal with the problem of shift work

C.a research on the normal human daily cycle

D.how to work better

Passage 1Archaeologists have long thought that stone ships served as graves for one or sev

Passage 1

Archaeologists have long thought that stone ships served as graves for one or several individuals, and have even been viewed as death ships _1_ to take the dead to living eternally. However, a new study conducted by researchers from the University of Gothenburg shows a different picture. It suggests Bronze Age stone monuments in the form. of ships were built by sailors as a symbol of their practices at sea. The study indicates that the stone ships and the activities that took place there point to people who were _2_ focused on practices at sea.Details found within the stone structures show they were built to _3_ real ships. The stone ships offer up _4_ about the ship-building techniques of the time and about the ships that sailed on the Baltic Sea during the Bronze Age. “These consist of areas that resemble hill forts and are located near easily _5_ points in the landscape—that is, near well-known waterways leading inland,” Wehlin, head of the team, said. “While these areas have previously been thought to be much younger, recent age _6_ have dated them to the Bronze Age.” Archaeologists have believed that bronze was _7_ to Scandinavia from the south, and recent analyses have helped confirm this _8_. However, the people who distributed the bronze objects are _9_ addressed in these thoughts. “One reason why the meeting places of the Bronze Age are not discussed very often is that we haven’t been able to find them,” Wehlin said. “This is in _10_ contrast to the trading places of the Viking Age, which have been easy to locate as they left behind such rich archaeological material.”

A) majorly

B) represent

C) evacuate

D) rarely

E) determinations

F) clues

G) anticipated

H) inquiries

I) intended

J) approximately

K) accessible

L) notion

M) inevitable

N) immense

O) imported
