With only about 1,000 pandas left in the world, China is trying to clone the animal and save the endangered species. That's a move similar to what a Texas University researcher has been undertaking for the past five years in a project called Noah's Ark.Dr. Duane Kraemer, a professor in Texas University and a pioneer in embryo (胚胎 ) transfer work and related procedures, says he salutes the Chinese effort and I wish them all the best success possible. It's a worthwhile project, certainly not an easy one, and it's very much like what we're attempting here to save animals from extinction.It is estimated that as many as 2,000 species of mammals, birds and reptiles will become extinct over the next 100 years. The panda, native only to China, is in danger of becoming extinct(灭绝的) 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 of one species to another is not easy, and the lack of available panda eggs could be a major problem, Kraemer believes. They will probably have to do several hundred transfers to result in one pregnancy. It takes a long time and it's 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 KraemerThey are trying to do something that's never been done, and this is very similar to our work in Noah's Ark. We're both trying to save animals that face extinction. I certainly applaud their effort and there's a lot we can learn from what they are attempting to do. It's a research that is very much needed.(1)The aim of Noah’s Ark project is to.A、implant embryo into a host animalB、salute the Chinese efforts in saving pandasC、save endangered animals from extinctionD、clone animals(2) How long will the Chinese panda cloning project take according to the passage?A、1 YearB、3 to 5 yearsC、2 years.D、25 years.(3) The word groundbreaking (Paragraph 5) means.A、essentially newB、pioneeringC、evolutionaryD、epoch making(4) What could be the major problem in cloning pandas according to Professor Kraemer?A、Lack of available panda eggs.B、Lack of host animals.C、Lack of qualified researchers.D、Lack of funds.(5) Which of the following is true?A、Animal cloning is an easy project.B、The panda is in danger of becoming extinct in the next 25 years.C、China cloned panda and saved the endangered species.D、They are certainly putting live pandas at risk.

The loss of biological diversity has become most spectacularly noticeable in extinction or decline of populations of large and well-known animals.Many animal species have become extinct since the 1700’s, among them the California grizzly bear, the dodo, and the passenger pigeon.Hundreds of other animal species are threatened.In North America, endangered species include the black-footed ferret, the California condor, the desert tortoise, and the whooping crane.Most species in danger of extinction anywhere in the world are suffering from the intrusion (侵入) of human beings.The Asian elephant, for example, has become an endangered species due to the expansion of the human population throughout its range in southern Asia.In Africa, the African elephants are being killed off for their tusks.Monkeys and other primates throughout the world are threatened by hunting, capture for medical use, and the destruction of their habitats.And the rhinoceroses, lions, and other large mammals of the African savanna (grassy plains with scattered trees) compete for land and life with some of the most rapidly growing human populations in the world.The loss of biological diversity is most severe, however, in the tropical rain forests.The forests of the tropics are particularly vulnerable to disturbance because the soils have a low capacity for retaining nutrients.Most of the forests’ nutrient elements are held in the tissues of plants.When loggers and farmers destroy existing plant cover, the nutrients are washed from the land into streams, and the land itself becomes less able to support life.Destruction of these forests destroys the habitat of hundreds, sometimes thousands, of species from such creatures as the howler monkey and indigo macaw, to less visible species of plants, insects, and microbes, many of which are not yet known to science.1.The author points out that species extinction ().A.is most noticeable in North AmericaB.is mainly taking place among large animalsC.quickened with industrialization of the societyD.never took place before the 1700’s2.Which of the following is NOT mentioned with regard to human intrusion?A.Elephants are killed off for their tusksB.Some primates are hunted for medical useC.Growing human population results in the competition for land and life among animalsD.Men live increasingly on animals as their source of food.3.The chief cause of the gradual disappearance of biological diversity is ().A.human crueltyB.human interferenceC.the increase of human populationD.the disappearance of the forests4.In tropical forests，().A.animals live a hard life due to competitionB.a lot of species die out for lack of foodC.rains constitute the major threat to speciesD.a greater number of animals are yet to be known5.It can be inferred that species extinction ().A.proceeds of a faster rate than noticeableB.is the worst among well-known animalsC.is the most severe in AfricaD.is chiefly due to competition among species

共用题干第二篇Where Have All the Frogs Gone?In the 1980s,scientists around the world began to notice something strange:Frogs were disappearing. More recent research has shown that many kinds of amphibians（两栖动物）are declining or have become extinct. They have been around for a long time一over 350 million years.Why are they dying out now?Scientists are seriously concerned about this question.First of all,amphibians are an important source of scientific and medical knowledge.By studying amphibians,scientists have learned about new substances that could be very useful for treating human diseases. Further research could lead to many more discoveries,but that will be impossible if the amphibians disappear.The most serious aspect of amphibian loss,however,goes beyond the amphibians themselves.Scientists are beginning to think about what amphibian decline means for the planet as a whole.If the earth is becoming unlivable for amphibians,is it also becoming unlivable for other kinds of animals and human beings as well?Scientists now believe that amphibian decline is due to several environmental factors. One of these factors is the destruction of habitat,the natural area where an animal lives. Amphibians are very sensitive to changes in their habitat.If they cannot find the right conditions,they will not lay their eggs一These days,as wild areas are covered with houses,roads,farms,or factories,many kinds of amphibians are no longer laying eggs. For example,the arroyo toad（蟾蜍）of southern California will only lay its eggs on the sandy bottom of a slow-moving stream.There are very few streams left in southern California,and those streams are often muddy because of building projects. Not surprisingily,the arrovo toad is now in danaer of extinction.There are a number of other factors in amphibian decline.Pollution is one of them.In many industrial areas,air pollution has poisoned the rain,which then falls on ponds and kills the frogs and toads that live there,In farming areas,the heavy use of chemicals oncrops has also killed off arrtphibians.Another factor is that air pollution has led to increasedlevels of ultraviolet (UV) light. This endangers amphibians, which seem to be especiallysensitive to UV light. And finally, scientists have discovered a new disease that seems tobe killing many species of arnpttibians in different parts of the world.All these reasons for the disappearance of amphibians are also good reasons for moregeneral concern. The destrriction of land, the pollcition of the air and the water, thechanges in our atmosphere, the spread of diseases-these factors affect human beings,too. Amphibians are especially sensitive to environmental change. Perhaps they are likethe canary （金丝雀）bird that coal miners once used to take down into the mines to detectpoisonous gases. When the canary became ill or died,the miners knew that dangerous gases were near and their own lives were in danger.Scientists think that the decline of amphibians couldA:cause environmental change.B:cause a decline in other kinds of animals.C:be a warning signal for human beings.D:be a good sign for human beings.
