The Moduleed Nations wanted everyone to know that the w

15、orld is in danger. They hoped that government would act quickly in order to conserve nature. Here is one example of the problem. At one time there were, 1,300 different plants, trees and flowers inHolland, but now only 860 remain. The others have been destroyed by modern man and his technology. We a

16、re changing the earth, the air and water, and everything that grows and lives. We cant live without these things. If we continue like this, we shall destory ourselves.What will happen in the future? Perhaps it is more important to ask，“What must we do now？”The people who will be living in the world

17、of tomorrow are the young of today. A lot of them know that conservation is necessary. Many are helping to save our world. They plant trees in forests, build bridges across rivers, and so on. In a small town in the Moduleed States a large group of girls cleaned the banks of eleven kilometers of thei

18、r river. Young people may hear about conservation through a record called NO ONES GOING TO CHANGE OUR WORLD. It was made by the Seattles, Cliff Richard and other singers. The money from it will help to conserve wild animals.36There are fewer plants, trees and flowers in Holland now because _.AHollan

19、d does not need so many plants, trees or flowersBmany plants, trees and flowers dont grow there any moreCsome of them are uselessDthey are polluted37We shall destroy ourselves if we dont_.Ago on cutting the plantsBbuild bridges across riversCtry our best to save the worldDconserve wild animals38NO O

20、NES GOING TO CHANGE OUR WORLD was_.Aan important book published in 1970Ba talk given by an official from the United NationsCa record calling on people to conserve natureDa film made to protect nature39What is the most important thing for us to do to save our world?AWe should join the singers to coll

21、ect money.BWe should stop hunting wild animals.CWe should know what would happen in the future.DWe should know what we should do and begin to do it now.BScientists have recently discovered that animals that live in groups, such as elephants, foxes, and wolves, are more likely to follow rules. If the

22、y dont, and each does its own thing, the group will probably break apart. Group members would be forced to live alone, and would have a harder time hunting and raising their young. Thats probably why a traveling wolf pack was seen stopping and waiting for its limping (跛行的) leader to catch up. Simila

23、r social ties are believed to be responsible for a captive elephant saving her friend from drowing.Sometimes, though, animals try their best to do whats right, even when theres nothing in it for them. Nobody knows exactly why.“It might simply feel good to be kind, just as it does for humans，”says Be

24、koff. If your friend wasnt nice to you, what would you do? Maybe you would just walk away. Thats exactly what a wild red fox did when she was playing boxing with another fox.Toby was a generous cat. For ten years, the kind kitty shared his food with a spaniel (长耳狗) named Katie. After supper, owner L

25、inda Gustafson always divided up the table scraps. Shed drop some in Katies bowl on the floor and some in Tobys dish on the kitchen counter. Gustafson kept the cats dish up high to keep Katie from stealing Tobys treats. As it turned out, Katie didnt need to steal; she only had to beg. Every night, t

26、he spaniel ate her food in a few seconds. Then shes sit and stare at the cat and every night. Toby would be nice. Using his paw, hed flick several pieces of tasty food down to the waiting pup. Apparetnly Katie appreciated it, because whenever she was curled up in her beanbag bed and the cat walked o

27、ver, she would give up her nice, warm spot.“Toby would then lie down in center of the beanbag，”says Gustafson, “and Katie would lie on the floor.”40The reason why some animals prefer to live in groups lies in that _.Athey have to follow natural rulesBthey are afraid of staying aloneCthey cannot find

28、 food by themselvesDliving alone would make their lives harder41According to Bekoff, animals try their best to do whats right because _.Ait feels good to be kindBanimals are friendly by natureCthey have learned to do so for a long timeDthey want their owners to like them42It can be inferred from the

29、 last paragraph that _.ALinda always lets the animals eat togetherBKatie sometimes gets her food by stealingCToby is generous but Katie isntDKatie and Toby help each otherCFar from the land of Antarctica(南极洲), a huge shelf of ice meets the ocean. At the underside of the shelf there lives a small fis

30、h, the Antarctic cod.For forty years scientists have been curious about that fish. How does it live where most fish would freeze to death? It must have some secret. The Antarctic is not a comfortable place to work and research has been slow. Now it seems we have an answer.Research was begun by cutti

31、ng holes in the ice and catching the fish. Scientists studied the fishs blood and measured its freezing point.The fish were taken from seawater that had a temperature of1.88and many tiny pieces of ice floating in it. The blood of the fish did not begin to freeze until its temperature was lowered to2

32、.05. That small difference is enough for the fish to live at the freezing temperature of the icesalt mixture.The scientists next research job was clear: Find out what in the fishs blood kept it from freezing. Their search led to some really strange thing made up of a protein (蛋白质) never before seen

33、in the blood of a fish. Whenitwas removed, the blood froze at seawater temperature. When it was put back, the blood again had its antifreeze quality and a lowered freezing point.X Kb 1.C o mStudy showed that it is an unusual kind of protein. It has many small sugar molecules (分子) held in special pos

34、itions within each big protein molecule. Because of its sugar content, it is called aglycoprotein. So it has come to be called the antifreeze fish glycoprotein, or AFGP.43What is the text mainly about?AThe terrible conditions in the Antarctic.BA special fish living in freezing waters.CThe ice shelf

35、aroundAntarctica.DProtection of the Antarctic cod.44Why can the Antarctic cod live at the freezing temperature?AThe seawater has a temperature of1.88.BIt loves to live in the icesalt mixture.CA special protein keeps it from freezing.DIts blood has a temperature lower than2.05.45What does the underli

36、ned word “it” in Paragraph 5 refer to?AA type of icesalt mixture.BA newly found proteinCFish blood.DSugar molecule.46What does“glyco”in the underlined word “glycoprotein” in the last paragraph mean?AsugarBiceCbloodDmoleculeDAnimal ConservationMany animal and plant species have become extinct and man

37、y more are in critical danger. Finding ways to protect the earths wildlife and conserve the natural world they inhabit (居住) is now more important than ever.DodosThe dodo is a classic example of how human caused damage to the earths biology. The flightless dodo was native to theIslandofMauritiusin th

38、eIndian Ocean. It lived off fruit fallen from the islands trees and lived unthreatened until humans arrived in 1505. The easily controlled bird became a source of food for sailors and was attacked by animals introduced to the island by humans such as pigs, monkeys and rats. The population of dodos r

39、apidly decreased and last one was killed in 1681.RhinosThe rhino (犀牛) horn is a highly prized item for Asian medicine. This has led to the animal being hunted in its natural habitat. Once widespread in Africa andEurasia, most rhinos now live in protected natural parks and reserves. Their numbers hav

40、e rapidly decreased in the last 50 years, and the animals remain under constant threat from poachers (偷猎者)The Giant PandasThe future of the World Wildlife Funds symbol is far from certain. As few as 1000 remain in the world.The Chinese government has set up 33 panda reserves to protect these beautif

41、ul animals and made poaching them punishable with 20 years in prison. However, The pandas distinct black and white patched coat fetches a high price on the black market and determined poachers still pose (造成) one of the most serious threats to the animals continued existence.WhalesThe International

42、Whaling Commission is fighting to ensure the survival of the whale species. Despite the fact that onethird the worlds oceans have been declared whale sancturaies (保护区), 7 out of 13 whale species remain endangered. Hunted for their rich supply of oil, their numbers have decreased to just 300. Collisi

43、ons with ships, poisonous pollution and being caught in fishing nets are other major causes of whale deaths.TigersThe last 100 years has seen a 95% reduction in the numbers of remning tigers to between 5000 and 7000 and theBali, Javan, and Caspian tiger are already extinct. TheSouth Chinatiger is precariously close to disappearing, with only 20 to 30 still alive. Like the rhino horn, tigers
