题目内容

Dolphins and sharks are showing up in surprisingly shallow

water just off the Florida coast. Mullets, crabs, rays and small

fish gather by the thousands off an Alabama pirer. Birds covered in

oil are crawling deep into marshes （沼泽）, never to be seen again.

Marine scientists studying the effects of the BP disaster（英国石油公司漏油事件）are seeing

some strange phenomena. Fish and other wildlife seem to be fleeing the oil out in the Gulf and clustering in cleaner waters along the coast in a trend that some researchers see as a potentially troubling sign. The animals' presence close to shore means their usual habitat is badly polluted, and the crowding could result in mass die-offs as fish run out of oxygen. Also, the animals could easily be captured by their enemies.

The nearly two-month-old spill（漏油）has created an environmental disaster in US history as tens of millions of gallons have flown into the Gulf of Mexico ecosystem. Scientists are seeing some unusual things as they try to understand the effects on thousands of species of marine life.

For nearly four hours Monday, a three-person crew with Greenpeace cruised past delicate

islands and mangrove-dotted inlets in Barataria Bay off southern Louisiana. They saw dolphins by the dozen frolicking（嬉戏）in the oily sheen（光泽）and oil-tinged pelicans feeding their young. But they spotted no dead animals.

"I think part of the reason why we're not seeing more yet is that the impacts of this crisis are

really just beginning," Greenpeace marine biologist John Hocevar said.

The counting of dead wildlife in the Gulf is more than an academic exercise; the deaths will

help determine how much BP pays in damages.

What do the marine life react to the BP disaster?

A．Birds crawl deep into caves.

B．Dolphins and sharks show up in deep water.

C．Tens of thousands of marine animals are found dead.

D．Sea creatures flee from oil spill, gathering near seashore.

Which of the following is NOT related to the potentially troubling sign?

A．The usual habitat of deep-water animals is badly polluted.

B．Many animals could be easily eaten by their enemies.

C．Masses of fishes could die due to lack of oxygen.

D．Some dolphins are frolicking in marshes.

The environmental disaster was caused by .

A．the damage of the Mexico Gulf ecosystem

B．the lack of environmental sense of BP

C．the nearly two-month-old oil spill

D．the crowding marine life

What is John Hocevar’s attitude towards the disaster?

A．Worried. B．Disappointed. C．Depressed. D．Hesitant.

From the passage, we can infer that .

A．Bp will pay much money according to the number of dead wildlife there

B．marine scientists have seen some strange phenomena

C．the disaster has little influence on dolphins

D．a three-person crew reached no conclusion

The USA, New York—Whales and dolphins are facing increasing threats from climate change, according to a new report published by WWF and the Whale and Dolphin Conservation Society （WDCS）．

The report "Whales in hot water?" draws attention to the growing impacts of climate change on whales．They range from changes in sea temperature and the freshening of the seawater because of the melting of ice and increased rainfalls, to a sea level rise, loss of icy polar habitats and the decline of krill populations in key areas．Krill, a tiny shrimp that is dependent on sea ice, is the main source of food for many of the great whales．

The speeding up of climate change adds greatly to trouble from other human activities, such as chemical and noise pollution, which kills some 1000 whales every day．

"Whales and dolphins have an ability to adapt to their changing environment," said Mark Simmonds, International Director of Science at WDCS．"But the climate is now changing at such a fast pace that it is unclear to what extent whales and dolphins will be able to adjust．"

Climate change impacts are currently greatest in the Arctic and the Antarctic．According to the report, cetaceans that rely on polar, icy waters for their home and food resources are likely to be greatly affected by the reduction of sea ice cover．

WDCS and WWF are urging governments to cut global production of C02 by at least 50 percent by the middle of this century．The latest report of the Intergovernmental Panel on Climate Change showed it was possible to stop global warming if the world's emissions start to decline before 2015．

Which of the following is the most important for whales and dolphins?

A．Rainfall B．Krill C．Sea ice cover D．High sea level

From the passage, we can learn that whales mainly feed on _____．

A．dolphins B．krill C．sea horses D．sharks

The underlined word "decline" in Paragraph 2 means _____．

A．increase B．control C．protection D．fall

In what place is climate change greatest?

A．The Pacific Ocean B．Asia．

C．Two polar areas． D．Equator．

Which of the following is not right according to the passage?

A．Climate change will lead to the changes in sea temperature．

B．Climate change will result in the freshening of the sea water．

C．Climate change will have a bad effect on human activities and whales．

D．Human beings will forever have no ability to stop global warming．

A perfect illustration of this attitude is the contrasting attitude towards another large sea animal, the dolphin. During the 1980s, environmentalists in the United States objected to the practice of hunting tuna (金枪鱼) in the Pacific Ocean since these nets also caught dolphins. The environmentalists generated enough political and economic pressure to prevent tuna companies from buying tuna that had been caught in drift nets. In contrast to this effort, the populations of sharks in the Pacific Ocean have decreased to the point of extinction and there has been very little effort by the same environmentalism to save this important species of wildlife in water. Sharks are among the oldest creatures on earth, having survived in the seas for more than 350 million years. They are extremely efficient animals, feeding on wounded or dying animals, thus performing an important role in nature of knocking out the weaker animals in a species. Just the fact that species such as the Great White Shark have managed to live in the oceans for so many millions of years is enough proof of their efficiency and adaptability to changing environment. It is time for humans, who may not survive another 1,000 years at the rate they are damaging the planet, to cast away their fears and begin considering the protection of sharks as creatures that may provide us with an insight into our own survival.

D. They brought political pressure against tuna companies.

Sharks have gained unfair reputation for being large fierce sea animals. That humanity’s unfounded fear and hatred of these ancient creatures are leading to a worldwide slaughter (大屠杀) may result in the extinction of many larger, coastal shark species. The shark is the victim of a warped (有偏见的) attitude of wildlife protection; we strive (努力) only to protect the beautiful, non-threatening parts of our environment. And, in our efforts to restore only non-threat parts of our earth, we ignore other important parts.

Top lists are lecturing people on everything from “100 places to visit” to “100 books to read ”.
Aren't you just tired of being told what to do with your time?
Now you have a list to end all lists!
Take a look at the following two examples from the list of “101 things not to do”:
Swim with Dolphins（海豚）？
Swimming with dolphins is one of the world’s most profitable tourist activities. However, every dolphin will welcome having their busy, tiring day interrupted by tourists screaming and pushing around them in the water. Worse yet, when dolphins get too near to the boats loaded with tourists, they could get caught up in ropes and killed by propellers(螺旋桨).
Here’s a little secret. Dolphins look like smiling at you, but actually they’re just opening their mouths.
Go to See the Mona Lisa?
There must be something about the mysterious(神秘的)smile. The 6 million people who visit the lady in the Louvre every year can’t all be wrong, after all. But they can be quite annoying, standing in front of you, holding up their cameras to prevent you from seeing anything. In fact, it is hard for you to see the painting clearly because you have to stay away from it for security reasons. After queuing for hours, many tourists can remain in front of the painting only for 15 seconds at most.
If the mysterious lady in the picture knew her fate, she wouldn’t just be smiling, she’d be laughing.
So, still long to see the Mona Lisa? If you want to find out more about the list, read 101 Things NOT to Do Before You Die. Visit www.not2dobeforeidie.co.uk and buy the book at a 20％ discount.
