Extinction is a difficult concept to grasp. It is an 26 _eternal____ concept. It’s not at all like the killing of individuals lifeforms that can be renewed through normal processes of reproduction. Nor is it simply 27 _diminishing____ numbers. Nor is it damage that can somehow be remedied or for which some substitute can be found. Nor is it something that simply affects our own generation. Nor is it something that could be remedies by some supernatural power. IT is rather an 28 __absolute____ and final act for which there is no remedy on earth or in heaven. A species once extinct is gone forever. However many generations 29___succeed__ us in coming centuries, none of them will ever see this species that we extinguish.
Not only are we bring about the extinction of life 30 _on a vast scale___, we are also making the land and the air and the sea so toxic that the very conditions of life are being destroyed. 31__As regards___ basic natural resources, not only are the nonrenewable resources being 32_used up____ in a frenzy(疯狂) of processing, consuming , and 33_disposing____, but we are also ruining much of our renewable resources, such as the very soil itself on which terrestrial(地球上的) life depends.
The change that is taking place on earth and in our minds is one of the greatest changes ever to take place in human affairs, perhaps the greatest, since what we are talking about is not simply another historical change or cultural 34__modification______, but a change of geological and biological as well as psychological order of 35__magnitude___
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.

听力原文： Britain has a variable climate. The weather changes so frequently that it is difficult to forecast. It is not unusual for people to complain that the weatherman was wrong. Fortunately, as Britain does not experience extreme weather conditions, it is never very cold or very hot. The temperature rarely rises above 32℃ in summer, or falls below—10℃ in winter.
Summers are generally cool, but due to global warming they are starting to get drier and hotter. Newspapers during a hot spell talk of "heat waves" and an "Indian summer"—dry, hot weather in September or October. Hot weather causes terrible congestion on the roads as Britons rush to the coastal resorts.
Winters are generally mild, with the most frequent and prolonged snowfalls in the Scottish Highlands, where it is possible to go skiing. If it does snow heavily in other parts of Britain, the country often comes to a standstill. Trains, buses and planes are late. People enjoy discussing the snow, complaining about the cold and comparing the weather conditions with previous winters!
Contrary to the popular opinion, it does not rain all the time. There is certainly steady rainfall throughout most of the year, but the months from September to January are the wettest. Thanks to the rain, Britain has a richly fertile countryside which is famous for its deep green colour.
Since the 1950s, most British cities have introduced clean air zones. Factories and houses cannot burn coal and must use smokeless fuel. The dirt caused by smoke used to cause terrible fogs, particularly in London. Londoners used to call their fogs "London Particulars" and you could not see your hand in front of you. Such fogs are now a thing of the past, but you can still see them in old films where they add mystery and atmosphere to murder stories and thrillers!

A．It's unusual.
B．It's sharp.
C．It's moderate.
D．It's unnoticeable.
听力原文： Last April, American businessman Dennis Tito reportedly paid between twelve-million and twenty-million dollars to spend one week on the International Space Station. NASA had strongly objected to the Russian plan to permit a civilian on the costly research vehicle. After two years of negotiations, space officials have agreed on a process to train private citizens to take trips to the International Space Station.
NASA recently agreed to conditions that will permit Russia to sell trips to the space station. An American company called Space Adventures Limited of Arlington, in Virginia plans the trips. Experts say the change in policy at NASA shows a new desire to use space vehicles for business and industrial purposes. In a speech to Congress last year, NASA official Michael Hawes said that the space agency had not considered civilian travel as one of the industries it wanted to develop. However, Mister Hawes said that private space travel could now be done as long as safety measures are observed carefully.
Candidates for adventure space travel trips must be in excellent health and must pass difficult health tests. They must receive a lot of training. However, Special English can help you prepare for a space holiday. This is because all successful candidates who wish to travel to the International Space Station must be able to read and speak English.
(30)
A．Because it welcomes t a big sum of money by tourist
B．Because it thinks that safety measures are followed carefully.
C．Because Russia agrees, too.
D．Because the spaceship is available.
Manned submersibles.(潜水器), like spaceships, must maintain living conditions in an unnatural environment. But while a spaceship must simply be sealed against the vacuum of space, a submersible must be able to bear extreme pressure if it is not to break up in deep water.
In exploring space, unmanned vehicles were employed before astronauts. In undersea exploration, on the other haled, men paved (铺路) the way, and only recently have unmanned remote-operated vehicles (ROVs) been put to use.
One reason for this is that communicating with vehicles in orbit is much easier than talking to those underwater. A vacuum is an ideal medium for radio communications, but underwater communications are limited to much slower sound waves. Thus, most undersea vehicles—particularly ROVs—operate. at the end of long process.
For a similar reason, knowing where you are undersea is much more difficult than in space. A spaceship's position can be located by following its radio signal, or by using telescopes and radar. For an undersea vehicle, however, a special network of sonar (声纳) devices most be laid out in advance on the ocean floor in the area of a dive to locate the vehicle's position.
Though undersea exploration is more challenging than outer space in a number of respects, it has a distinct advantage: Going to the ocean doesn't require the power necessary to escape Earth's gravity. Thus, it remains far less expensive.
People did not begin to use unmanned vehicles in undersea exploration until recently because of ______.
A．the ocean depths
B．the communication problem
C．the movement of waves
D．the problem of vacuum
Admittedly, rough acts in sports are difficult to police. But here, too, we find reflected the conditions of everyday life. Ambiguities in the law, confusion at the scene, and the reluctance of witnesses cloud almost any routine assault case. Such uncertainties, however, have not prevented society from arresting people who strike their fellow citizens on the street.
Perhaps our troubles stem not from the games we play but rather from how we play them. The 1979 meeting between hockey(曲棍球) stars from the Soviet Union and the National Hockey League provided a direct test of two approaches to sport—the emphasis on skill, grace, and finesse(技巧) by the Russians and the stress on brutality and violence by the NHL. In a startling upset, the Russians embarrassed their rough-playing opponents and exploded a long-standing myth: that success in certain sports requires excessive violence.
Violence apologists cite two additional arguments: First, they say, sports always have been rough; today things are no different. But arguments in America's Old West Were settled, on Main Street with six-guns, and early cave-dwellers chose their women with a club. Civilizing influences ended those practices; yet we are told sports violence should be tolerated. The second contention is that athletes accept risk as part of the game, and, in the case of professionals, are
paid handsomely to do so. But can anyone seriously argue that being an athlete should require the acceptance of unnecessary physical abuse？ And, exaggerated as it may seem, the pay of professional athletes presumably reflects their abilities, not a payment against combat injuries.
"Clearly we are in deep trouble," says perplexed former football player AL DeRogatis. "But how and why has it gotten so bad？"
According to the author, the distinction between violent acts and non-violent ones in sports is ______.
A．impossible to make
B．not very clear in any circumstances
C．too obvious to escape observation
D．not very difficult to make if enough attention is paid to
If this view is correct and the world's temperature is raised only a few degrees, much of the polar ice cap will melt and cities such as New York, Boston, Miami, and New Orleans will be under water.
Another view, less widely held, is that increasing particular matter in the atmosphere is blocking sunlight and lowering the earth's temperature—a result that would be equally disastrous. A drop of just a few degrees could create something close to a new ice age, and would make agriculture difficult or impossible in many of our top farming areas. At present we do not know for sure that either of these conditions will happen (though one recent government report prepared by experts in the field concluded that the greenhouse effect is very likely). Perhaps, if we are very lucky, the two tendencies will offset each other and the world's temperature will stay about the same as it is now.
As is pointed out at the beginning of the passage, people used to think that air pollution ______.
A．caused widespread damage in the countryside
B．affected the entire eastern half of the United States
C．had damaging effects on health
D．existed merely in urban and industrial areas
