Dolphins are interesting animals and researchers find them interesting to watch. They don’t have hands, but can use tools to solve problems, just like us. Scientists have observed a dolphin trying to get a shy eel(鳝鱼) to come out of its hole by poking(捅)it with a dead fish. Many species of dolphin live in large societies. They have many different relationships and need a good communication system; they use a variety of sounds to communicate with each other.

There is currently no evidence that dolphins have a language of their own. But scientists still have a lot to find out about these animals and so there are certain to be a few surprises in the future.

At Kewalo Basin Marine Laboratory in Hawaii, the dolphin team have developed a sign langue to communicate with the dolphins, and the results are amazing. Not only do the dolphins understand the meaning of individual words, they also understand the significance of word order in a sentence. For example, when they were asked to ‘touch the ball with your tail and then jump over it’ they generally responded correctly and straight away, which showed that they understood the langue.

Most mammals seem to enjoy play—but dolphins seems to like making their games as challenging as possible. On a beautiful day in 1997, researchers working at a beach, off the southern coast of Brazil, observed a little dog going into the sea and swimming towards the dolphins. To their surprise, the dolphins approached the dog and then started throwing it into the air. The dog seemed to enjoy the ‘game’ and continued playing with the dolphins for more than an hour. From then on, different dogs were seem trying to interact with the dolphins.

Dolphins live in a very different world to ourselves, but they are very good at our ‘intelligence tests’. For example, they will jump out of the water when they hear a whistle noise. They do this because they will get a fish as a reward. There is still much to learn about these flexible(灵活的)problem-solvers, but from the evidence so far, it would seem as though dolphins are very intelligent.

1.To get a shy eel to come out of its hole , a dolphin would poke it with____.

A.a tool

B.its tail

C.a dead fish

D.its mouth

2.At a laboratory in Hawaii, the dolphin team have developed a ____ to communicate with the dolphins.

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.

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.

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.

The best summary of the passage is __________.

   A. sharks have such a bad reputation

   B. how sharks become some of the oldest creatures on earth

   C. sharks should be put under wildlife protection

   D. the campaign to save dolphins was not extended to save sharks

How long have sharks been living on the planet?

   A. More than 25 million years.

   B. More than 150 million years.

   C. More than 350 million years.

   D. More than 500 million years.

Which of the following best describes the organization of this passage?

   A. Specific(细节) to general.                B. Cause and effect.

   C. Statement and example.                  D. Time order.

How did environmentalists manage to protect dolphins?

   A. They prevented fishermen from selling them for meat.

   B. They pressured fishermen into protecting dolphins by law.

   C. They created shelters where dolphin fishing was not allowed.

   D. They brought political pressure against tuna companies.

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.
