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

资料：As a startup founder, my daily tasks include everything from long-term strategic planning to approving team outings and company culture initiatives. Day after day, things inevitably come up that need to get handled ASAP. But I’ve also learned that if you don’t have a strategy for making time for those bigger ambitions and your truly lofty goals, they’ll simply never get done. And that means you won’t make the progress that’s really going to move your business forward.1. FIND YOUR MOST PRODUCTIVE TIMEFace it: You aren’t cranking out work at absolute peak productivity for the entire day. Instead, there are likely certain times when you’re at your most focused and other times when your energy wanes. That’s normal. Maybe for you, it’s bright and early in the morning, before anyone else arrives in the office, when you do your best work. Whenever it is, identify that chunk of time （even if it’s only an hour!） when you feel most productive, and then reserve it on your calendar like you would any other important meeting. You need to protect this block of time from intrusion--it isn’t optional. That way you’re guaranteed to have a regular, designated period when you can at least get started on those bigger to-dos.2. CREATE PHYSICAL BARRIERSNobody works in a vacuum. We all have to collaborate with others to some degree or another. And it’s the people we work closest with whom we tend to put first--we want to be readily available if they need our help. But there are times you need to tune out the distractions and focus if you’re going to get any meaningful work done.One of the most effective methods I’ve found is to put physical barriers between us. I’ll work from a conference room or even from home on occasion in order to get some literal space from people needing “just one quick thing.”What may the author discuss later?A.The author may talk about the administration system.B.The author may teach the readers to make a timetable.C.The author may put forward another suggestion.D.The author may discuss the office environments.

单选题Which of the following scenarios would best sport the position given in Passage 2 ?AThe gradual migration of a herd of elephants into new territory due to a shortage of water and food in their original habitatBAn increase in prehensile taft strength after a species of monkeys began living among taller trees to avoid terrestrial predatorsCThe sudden extinction of a breed of wild donkeys following a dramatic change in climateDThe discovery of prehistoric fossils demonstrating the existence of a creature with both mammalian and amphibious characteristicsEThe discovery of a previously unknown species of crocodile in waters traditionally considered too cold for reptiles
问答题Practice 2 The destiny of wild places in the 21 century can be read in the numbers. The pressure to exploit the world’ s remaining wilderness for natural resources, food and human habitation will become overwhelming. But bulldozers and chain saws aren’t the only threats. A new menace has emerged from the least likely quarter; in many cases, the very people who care most passionately about empty places are hastening their demise. Backcountry activities have become extremely trendy in the U. S., a fad that has been eagerly abetted by Madison Avenue. These days it’s impossible to turn on a television or open a magazine without being assaulted by a barrage of ads that use skillfully packaged images of wilderness activities to rev the engine of consumerism. Disconcerting though this development may be, it happens to come with a substantial upside; because wilderness is now esteemed as something precious and/or fashionable, wild places are more often being rescued from commercial exploitation. But if the wilderness fad has made it easier to protect wild country from development, it has made it harder to protect wild country from the exploding ranks of wilderness enthusiasts. Increasingly, places once considered enduringly back of beyond are now crowded with solitude seekers. As wilderness dwindles and disappears, more is at stake than the fate of endangered species. Other, less tangible things stand to be lost as well. Empty places have long served as a repository for a host of complicated yearnings and desires. As an antidote to the alienation and pervasive softness that plague modern society, there is no substitute for a trip to an untrammeled patch of backcountry, with its attendant wonders, privation and physical trials.

问答题The Truth about Genetically Modified Food At almost every public lecture I give, someone asks me my opinion on genetic modification—whatever be the topic of the lecture. Genetic modification (GM) has the power to save lives through its use in medicine, such as the production of insulin for diabetics or the treatment of genetic disorders. The current outcry comes when it is used to produce food. Some of these public concerns reflect real problems, but others are fuelled by misinformation and overdramatisation. There is nothing new about crop modification; plant breeders have been doing it since agriculture began. The wonderful range of apples or potatoes we now enjoy is the result of crossing different varieties. Cabbages, Brussels sprouts, cauliflower, kohlrabi, kale and broccoli all originated from one botanical species. Modern molecular biology has enabled us to go much further. We can now isolate the gene for a particular characteristic of an organism and transfer it to another species. It is this practice of transforming a plant with alien genes—perhaps from an animal or bacterium—that is causing all the controversy. There are three main concerns. Scientists can now take a gene for resistance to a particular herbicide and transfer it to a crop: when these plants are sprayed with weed-killer, the weeds are destroyed while the crop is unharmed. A prime concern is the harmful effect this could have on the biodiversity of farmland, where so many insects, birds and other animals depend upon “weed” species. Another fear is that alien genes from a GM plant could escape into a wild population of a related species. Since plants are fertilized by pollen that is carried through their, often for great distances, this is entirely possible. A wild species modified in this way with pesticide resistance could become a “super-weed”, while a species that becomes unnaturally resistant to animals that feed on it could disrupt the food chain. The third worry concerns a proposal to produce seeds for cereals that cannot germinate to produce next year’s seeds. This “terminator technology” would be of obvious advantage to seed companies, since farms would be forced to buy new weed annually. But the same technology could be devastating to some farmers in the developing world who depend upon saving some seeds for next year’s crop. Fortunately this technology is not yet in use and there has been strong pressure to abandon it. I would not hesitate to eat a GM vegetable—it is most unlikely that the current modifications are harmful to the consumer, despite what we read in the press. However, the introduction of animal genes into food plants presents considerable ethical difficulties to vegetarinsarians and member of religious that forbid the eating of certain animals. This is one of the reasons people are demanding that tall genetically modified food products be clearly labeled. The public have a fight to know what they are eating and a fight to choose. I believe that in my own nation GM is well regulated, but this cannot be said for some other countries. One of the problems is that at the moment this technology is commercially motivated. Because the compositions developing GM food want to introduce it as quickly as possible, in my opinion, it is being rushed into without adequate research or precautions. Genetic’ modification is here to stay, and there is no doubt it will save lives. But ,like so many other scientific discoveries, such as splitting the atom, it can be seriously misused. Instead of condemning the technique, we, should ensure it is used wisely. We need to evaluate each application carefully, from environmental and ethical standpoints, and we must urge governments and companies to use it for good rather than for greed.
