In cooperation with Chinese local and state government agencies, the Conservancy established the Yunnan Great Rivers Project, which protects an area about the size of West Virginia.Did you know?China contains 10% of the worlds total species.At least 15% of Chinas mammal species and 8% of its bird species are found nowhere else on Earth.Nearly 15,000 plant species are native to Yunnan Province.Yunnan is home to 75% of Tibetan medicinal herbs and 30 endangered species.What is the Nature Conservancy trying to do?Education for Sustainability (可持续性)The Nature Conservancy recognizes that environmental education is an important element of working closely with local communities to achieve sustainable conservation results. In response, the Conservancy launched a new program called Education for Sustainability which tests means of teaching and learning that combine conservation goals, social justice, and appropriate development and participation in a vision and mission for personal and social change.Promoting Green TourismTourism is both an environmental threat and an economic opportunity, with the potential to provide extremely needed income to northwest Yunnan. The Conservancy is working with local communities, government agencies, and tourism ,enterprises(企业) to develop strategies for “green” tourism which will limit the footprint of mass tourism while generating income for local people. In addition to combining tourism development and management at our five action sites, we assisted with regional marketing efforts to promote eco-tourism opportunities.56.

He studied the observations of comets which other scientists had made. The orbit of one particular comet was a very difficult mathematical problem. He could not figure it out. Neither could other scientists who dealt with such problems.However, Halley had a friend named Isaac Newton. Who was a brilliant mathematician. Newton thought he had already which he had done it. He told Halley that the orbit of a comet had the shape of an ellipse.Now Halley set to work. He figured out the orbits of some of the comets that had been observed by scientist. He made a surprising discovery. The comets that had appeared in the years 1531, 1607 and 1682 all had the same orbit. Yet their appearances had been 75 to 76 years apart.This seemed very strange to Halley. Three different comets followed the same orbit. The more Halley thought about it, the more he thought that there had not been three different comets, as people thought. He decided that they had simply seen the same comet three times. The comet had gone away and had come back again.It was an astonishing idea! Halley felt certain enough to make a prediction of what would happen in the future. He decided that this comet would appear in the year 1758. There were 53 years to go before Halleys prediction could be tested.In 1758 the comet appeared in the sky. Halley did not see it, for he had died some years before. Ever since then that comet been called Halleys comet, in his honor.60.

Isaac Newton was a famous mathematician.D. The orbit of a comet had the shape of an around.CMillions of years ago dinosaurs lived on the earth. In the days of dinosaurs, the whole earth was warm and wet. There were green forests and they could find enough to eat. Later, parts of the earth became cold and dry, and the forests there died. Then dinosaurs could not find enough to eat. This must be one reason why dinosaurs died out.We can guess another reason. New kinds of animals came on the earth. Some had big brains and strong .They could kill dinosaurs.There may be other reasons that we dont know about yet. Scientists are are trying to make more discoveries about dinosaurs. Dinosaurs were of many sizes and shapes. Some were as small as chickens, while some were about 90 feet long.There were also terrible rights between dinosaurs. They night have happened more than 100 million years ago. Though there was no man to see any of the fights, we can be told by the animals footprints(足迹)that fights did take place .64. According to the passage, dinosaurs did exist only on the earth _.A. for millions of year B. millions of years agoC. more than 100 million years agoD. when it was warm and wet somewhere65. One reason why dinosaurs died out is that _.A. there were too many dinosaurs B. parts of the earth became cold and dry C. the dead forests there could not supply them with enough food D. they couldnt find enough go eat66. One more reason why dinosaurs died out may be that _.A. new kinds of animals came on the earth B. some fast and strong animals with big brains could kill them C. some dinosaurs were as small as chickensD. some big dinosaurs died in the fights67. We can see from this passage _.A. scientists are trying to make some dinosaurs B. dinosaurs are dangerous enough C. dinosaurs are worth studying D. scientists know nothing about dinosaursDThe blue tits(山雀) have been inspecting the nest-box again this year. The male is the house-hunter but the female will make the final choice. He lands at the hole and turns his head to expose his white cheeks as a signal to attract the female from where she has been feeding. Among many birds that nest in holes, the male has a light-coloured patch on its plumage(鸟羽) which acts as signal for drawing the females attention to a suitable nesting-place. Unlike the blue tit, the redstart(红尾鸲) may be only the male that strikingly coloured and the female is not beautiful. A few years ago I was lucky enough to spot a pair of redstarts in action in a Walsh wood. The male was leading an interested female to holes that he had previously(先前) checked out. He sat at the entrance of each hole and put his head on to show off his white forehead, or his head in to reveal(显露) his tail. If the female failed to react to his visual signals, the male sometimes sang for extra effect, while gliding towards her on spread wings and tail. Once the female accepts by following the male through the hole the displays stop, you must be at the right place at the right time to watch them. 68 How do the blue tits choose their nest?A. They choose their nest together. B. The male chooses their nest. C. The house-hunter chooses their nest. D. The female chooses their nest. 69. The writer was lucky to see _. A. how the male made his tricksB. how an interested female played with the male happilyC. what the male displayed and won the femaleD. that the male tried his best but failed to attract the female70. You can spot a pair of redstarts in a Walsh wood _. A. at any timeB. regularly C. in April D. occasionally71. The writer is probably _. A. a bird expert B. a bird-hunterC. a bird raiser D. a scientistEWith only about 1, 000 pandas left in the world, China is desperately trying to clone(克隆) the animal and save the endangered species(物种). Thats a move similar to what a Texas A & M University researchers have been undertaking for the past five years in a project called “Noahs Ark”. Noahs Ark is aimed at collecting eggs, embryos(胚胎), semen and DNA of endangered animals and storing them in liquid nitrogen. If certain species should become extinct, Dr. Duane Kraemer, a professor in Texas A & Ms College of Veterinary Medicine, says there would be enough of the basic building blocks to reintroduce the species in the future. It is estimated that as many as 2, 000 species of mammals, birds reptiles will become extinct in over 100 years. The panda, native only to China, is in danger of becoming extinct in the next 25 years. This week, Chinese scientists said they grew an embryo by introducing cells from a dead female panda into the egg cells of a Japanese white rabbit. They are now trying to implant the embryo into a host animal. The entire procedure could take from three to five years to complete. “The nuclear transfer(核子移植) of one species to another is not easy, and the lack of available(capable of being used) panda eggs could be a major problem,” Kraemer believes. “They will probably have to do several hundred transfers to result in one pregnancy (having a baby). It takes a long time and its difficult, but this could be groundbreaking science if it works. They are certainly not putting any live pandas at risk, so it is worth the effort,” adds Kraemer, who is one of the leaders of the Project at Texas A& M, the first-ever attempt at cloning a dog. “They are trying to do something thats never been done, and this is very similar to our work in Noahs Ark. Were both trying to save animals that face extinction. I certainly appreciate their effort and theres a lot we can learn from what they are attempting to do. Its a research that is very much needed.” 72. The aim of “Noahs Ark” project is to _.A. make efforts to clone the endangered pandasB. save endangered animals from dying outC. collect DNA of endangered animals to studyD. transfer the nuclear of one animal to another73. According to Professor Kraemer, the major problem in cloning pandas would be the lack of _.A. available panda eggsB. host animalsC. qualified researchersD. enough money74. The best title for the passage may be _.A. Chinas Success in Pandas Cloning B. The First Cloned Panda in the World C. Exploring the Possibility to Clone Pandas D. China the Native Place of Pandas Forever75. From the passage we know that _.A. Kraemer and his team have succeeded in cloning a dog B. scientists try to implant a pandas egg into a rabbit C. Kraemer will work with Chinese scientists in clone researches D. about two thousand of species will probably die out in a centuryIV 阅读表达Do you want to live another 100 years or more? Some exports say that scientific advances will one day enable humans to last tens of years beyond what is now seen as the natural limit of the human life span.“I think we are knowing at the door of immortality(永生).”said Michael Zey, a Montclair State University business professor and author of two books on the future. “I think by 2075_ and thats a conservative estimate(保守估计的).”At the conference in San Francisco, Donald Louria, a professor and author at New Jersey Medical School in Newwark said advances in using genes as well as nanotechnology（纳米技术）make it likely that humans will live in the future beyond what has been possible in the past. “There is a great push so that people can live from 120 to 180 years.” He said.“Some have suggested that there is no limit and that people could live to 200 or 300 or 500 years.” However, many scientists who specialize in aging are doubted about it and say the human body is just not designed to last past about 120 years. Even with healthier lifestyles and less disease, they say failure of the brain and organs will finally lead all humans to death. Scientists also differ on what kind of life the super aged might live. “It remains to be seen if you pass 120, you know; could you be healthy enough to have good quality of life? ” said Leonard Poon, director of the University of George Gerontology Centre. “At present people who could get to that point are not in good health at all.”76.
