Passage 2 A new form of cloning to provide every baby with an embryonic “twin”, from which spare body parts could be grown and life threatening diseases treated is expected to be approved within weeks by senior government advisers on medical ethics. If their report is accepted by ministers, it would mean that Britain—which 20 years ago pioneered the test tube baby and last year produced Dolly, the world’s first cloned mammal—could be the first to clone a human embryo. A working party from the Human Fertilisation and Embryology Authority (HFEA) and the Human Genetics Advisory Commission is expected to come down firmly against reproductive cloning, the process of replicating a living human being. It is expected to recommend government support of so called stem ceils. Stem cells are extracted and used to grow spare parts, treat diseases such as Alzheimer’s and Parkinson’s or address the debilitating effects of cancer, strokes and heart attacks. Dr Austin Smith, the scientist likely to be granted the first licence for the work, said that within the next 12 years it would be routine for every baby to have an embryonic clone. “All it takes now is financial investment,” said Smith, director of Edinburgh University’s centre for genome research. The crucial discovery of embryonic stem cells, from which skin, bone, muscles, nerves and vital organs grow, was made earlier this month by scientists in America. In a submission to the HFEA, Smith said that in order to isolate these cells it is only necessary for the embryo to develop in the laboratory for six days, well within the 14-day limit of current regulation. The cells would then be grown and manipulated to make anything from blood or brain cells to tissue for repairing damaged organs and, ultimately, parts that could be transplanted without fear of the host body rejecting them. The development is likely to meet strong opposition from the church. Dr Donald Bruce, Director of the Society, Religion and Technology Project of the church of Scotland Said that creating an embryo in the knowledge that it would then be destroyed was “very disturbing” to most people. Father Paul Murray, secretary to the Catholic bishops joint bio-ethics committee, said that whatever the potential benefits, it should be regarded as “intrinsically evil” because the research depended on the use of foetal material. However, Professor Christine Gosden, professor of genetic medicine at Liverpool University, one of the four senior government advisers on the cloning sub-committee, said there would be no opportunity for abuse. For many years, patients with Parkinson’s disease who did not respond to drugs have been treated with brain cells extracted from aborted foetuses, a practice approved by a committee led by the Rev Dr John Polkinghorne, the prominent ethicist. Gosden said the arguments for the use of aborted foetal cells and therapeutic cloning were similar: “Before you have a disease, it is easy to say, ‘I would not use cells derived from a foetus’, but if you suffer from that disease, and that is your only hope, your approach can be quite different.” 1.

Hello, new students! This is a message from the Students Union Committee. We've been at the university for at least a year now, so we can give you some good tips. Don't worry - we remember being new and making a lot of mistakes! And we haven't forgotten feeling a little bit scared. First, as you know, there are no longer any grants. If you borrow money from the government, remember that like all loans, you have to pay it back. Spending all your money in the first week is not a sensible strategy. Try to make a budget for each term and stick to it. But if you are struggling to make ends meet, you can get a part-time job-restaurants and bars in the town take lots of students on in the evenings and at weekends. Come and see us for advice. Stop worrying about making new friends. Start to join the sports and hobbies societies - they're cheap and you can begin meeting a lot of people that way. It's a great chance to take up a completely new hobby. Living in a new city a long way from home can be very stressful. One tip, don't forget your parents. After all, they are paying your tuition fees here. You will be very busy working and enjoying yourself, but stop to phone your parents sometimes and don't forget to go home for the weekend from time to time. And remember to take your dirty washing! Finally, remember to work hard and play hard. Go on working steadily towards your first degree (BA or BSc) throughout your three years here - try to keep things in perspective. You'll always find someone in the Student Union office if you need to talk.1). What does the word "scared" mean in the second paragraph?2). What does the word "grants" mean in the third paragraph?3). The sentence "But if you are struggling to make ends meet, ?at weekends" in the third paragraph implies().4). From the fifth paragraph, we can infer that in order to overcome the stress of living faraway from home, ().5). This passage is written for the purpose of ().(1).A、excitedB、frightenedC、worried(2).A、money given by the government to support the students' study, which they needn't pay backB、money from the government which the students need to pay backC、money from the school which is similar to scholarship(3).A、if you are short of money, you can find a part-time job in the restaurants and bars in your spare timeB、if you want to have a better life than others, you can find a part-time job in your spare timeC、restaurants and bars need more hands in the evenings and at weekends(4).A、it's better for new students to talk to their parents over the phone from time to timeB、new students need to do their washing themselvesC、new students should keep themselves as busy as possible so that they will not miss home(5).A、telling new students the problems facing them in the universityB、telling new students how to budget their moneyC、offering new students some advice about their university life

Passage FiveIn every language there are two great classes of words which, taken together, consist of the whole vocabulary. First, there are those words with which we become acquainted in daily conversation, which we learn, that is to say, from the members of our own family and from our familiar associates, and which we should know and use even if we could not read or write. They concern the common things of life, and are the goods in trade of all those who speak the language. Such words may be called "popular", since they belong to the whole people; and are not the exclusive possession of a limited class.On the other hand, our language includes a large number of words which are comparatively seldom used in ordinary conversation. Their meanings are known to every educated person, but there is little occasion to use them at home or in the market-place. Our first acquaintance with them comes not from our mother's lips or from the talk of our school-mates, but from books that we read, lectures that we bear, or the more formal conversation of highly educated speakers who are discussing some particular topic in a style. raised above the habitual level of everyday life. Such words are called "learned". And the distinction between them and "popular" words is of great importance to a right understanding of the language.51. One class of words can be learned ______.A. through everyday lifeB. without too much practiceC. from popular songsD. with a dictionary in one's hand

考题
Part A 2 BBC ‘s Casualty programme on Saturday evening gave viewers a vote as to which of two patients should benefit from a donation. But it failed to tell us that we would not need to make so many life-and-death decisions if we got to grip with the chronic organ shortage. Being pussyfooting around in its approach to dead bodies, the Government is giving a kicking to some of the most vulnerable in our society. One depressing consequence of this is that a significant number of those on the waiting list take off to foreign countries to purchase an organ from a living third-world donor, something that is forbidden in the United Kingdom. The poor have no option but to wait in vain.The Human Tissue Authority’s position on the retention of body parts for medical research after a post-mortem examination is equally flawed. The new consent forms could have been drafted by some evil person seeking to stop the precious flow of human tissue into the pathological laboratory. The forms are so lengthy that doctors rarely have time to complete them and, even if they try, the wording is so graphic that relatives tend to leg it before signing. In consequence, the number of post mortems has fallen quickly.The wider worry is that the moral shortsightedness evident in the Human Tissue Act seems to infect every facet of the contemporary debate on medical ethics. Take the timid approach to embryonic stem cell research. The United States, for example, refuses government funding to scientists who wish to carry out potentially ground-breaking research on the surplus embryos created by IVF treatment.Senators profess to be worried that embryonic research fails to respect the dignity of “potential persons”. Rarely can such a vacuous concept have found its way into a debate claming to provide enlightenment. When is this “potential” supposed to kick in? In case you were wondering, these supposedly precious embryos are at the same stage of development as those that are routinely terminated by the Pill without anyone crying. Thankfully, the British Government has refused the position of the United States and operates one of the most liberal regimes in Europe, in which licences have been awarded to researchers to create embryos for medical research. It is possible that, in years to come, scientists will be able to grow organs in the lab and find cures for a range of debilitating diseases.The fundamental problem with our approach to ethics is our inability to separate emotion from policy. The only factor that should enter our moral and legal deliberations is that of welfare, a concept that is meaningless when applied to entities that lack self-consciousness. Never forget that the research that we are so reluctant to conduct upon embryos and dead bodies is routinely carried out on living, pain-sensitive animals.第6题：Which of the following is true of Sony’s acquisition of Columbia Pictures?［A］ It was motivated by Morita’s desire to project an image of success.［B］ Sony’s top executives were quite convinced of its benefits for the company.［C］ Entertainment industry insiders believed it was the failure of Hollywood.［D］ It was the expensive expansion from electronics into entertainment.

Promising Resnlts from Cancer StudyA new experimental vaccine（疫苗）has shown promising results in the fight against lung cancer.In a small Texas-based study,a vaccine developed by scientists at Baylor University Medical Centre in Dallas,USA,cured lung cancer in some patients and slowed the progress of the disease in others.Researchers have reported encouraging findings from this small study.Forty一three patients suffering from lung cancer were involved in these trials.Ten of these patients were in the early stages and thirty-three in tho advanced stages of the disease.They were injected with the vaccine every two weeks for three months,and were carefully monitored for three years.In three of the patients in the advanced stages of cancer,the disease disappeared and in the others,it did not spread for five to twenty-four months.However,no great difference was seen in the patients in the early stages of the illness.This new vaccine uses the patient's own immune system.It is made specifically for each patient and is injected into the arm or leg.It stimulates（刺激）the body's immune system, which then recognizes that the cancer cells are harmful,and attacks and destroys them.The vaccine could be effective against other forms of cancer.It offers great hope for the treatment of cancer in general,although further studies are needed before such treatment can be widely used.Every patient was injected with the same vaccine.A:RightB:WrongC:Not mentioned

问答题Practice 5 We hold these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain unalienable rights, that they are among these are life, liberty and the pursuit of happiness. That to secure these rights, governments are instituted among them, deriving their just power from the consent of the governed. That whenever any form of government becomes destructive of these ends, it is the right of the people to alter or to abolish it, and to institute new government, laying its foundation on such principles and organizing its powers in such form, as to them shall seem most likely to effect their safety and happiness. Prudence, indeed, will dictate that governments long established should not be changed for light and transient causes; and accordingly all experience has shown that mankind are more disposed to suffer, while evils are sufferable, than the right themselves by abolishing the forms to which they are accustomed. But when a long train of abuses and usurpations, pursuing invariably the same object evinces a design to reduce them under absolute despotism, it is their right, it is their duty, to throw off such government, and to provide new guards for their future security. Such has been the patient sufferance of these Colonies; and such is now the necessity, which constrains them to alter their former systems of government.

问答题Practice 1 After nearly a year of emotional arguments in Congress but no new federal laws the national debate over the future of human cloning has shifted to the states. Six states have already banned cloning in one form or another，and this year alone 38 anticloning measures were introduced in 22 states. The resulting patchwork of laws，people on all sides of the issue say，complicates a nationwide picture already clouded by scientific and ethnical questions over whether and how to restrict cloning or ban it altogether. Since l997，when scientists announced the birth of Dolly the sheep，the first cloned mammal，the specter of cloned babies, infants that ate，in essence，genetic carbon copies of adults has loomed large in the public psyche and in the minds of lawmakers. Today, there is widespread agreement that cloning fur reproduction is unsafe and should be banned. Now，the debate has shifted away from the ethics of baby-making and toward the morality of cloning embryos for their cells and tissues，which might be used to treat diseases. The controversy pits religious c6nservatives and abortion opponents, who regard embryos as nascent human life，against patients' groups，scientists and the biotechnology industry.

问答题Passage 2 A new form of cloning to provide every baby with an embryonic “twin”, from which spare body parts could be grown and life threatening diseases treated is expected to be approved within weeks by senior government advisers on medical ethics. If their report is accepted by ministers, it would mean that Britain—which 20 years ago pioneered the test tube baby and last year produced Dolly, the world’s first cloned mammal—could be the first to clone a human embryo. A working party from the Human Fertilisation and Embryology Authority (HFEA) and the Human Genetics Advisory Commission is expected to come down firmly against reproductive cloning, the process of replicating a living human being. It is expected to recommend government support of so called stem ceils. Stem cells are extracted and used to grow spare parts, treat diseases such as Alzheimer’s and Parkinson’s or address the debilitating effects of cancer, strokes and heart attacks. Dr Austin Smith, the scientist likely to be granted the first licence for the work, said that within the next 12 years it would be routine for every baby to have an embryonic clone. “All it takes now is financial investment,” said Smith, director of Edinburgh University’s centre for genome research. The crucial discovery of embryonic stem cells, from which skin, bone, muscles, nerves and vital organs grow, was made earlier this month by scientists in America. In a submission to the HFEA, Smith said that in order to isolate these cells it is only necessary for the embryo to develop in the laboratory for six days, well within the 14-day limit of current regulation. The cells would then be grown and manipulated to make anything from blood or brain cells to tissue for repairing damaged organs and, ultimately, parts that could be transplanted without fear of the host body rejecting them. The development is likely to meet strong opposition from the church. Dr Donald Bruce, Director of the Society, Religion and Technology Project of the church of Scotland Said that creating an embryo in the knowledge that it would then be destroyed was “very disturbing” to most people. Father Paul Murray, secretary to the Catholic bishops joint bio-ethics committee, said that whatever the potential benefits, it should be regarded as “intrinsically evil” because the research depended on the use of foetal material. However, Professor Christine Gosden, professor of genetic medicine at Liverpool University, one of the four senior government advisers on the cloning sub-committee, said there would be no opportunity for abuse. For many years, patients with Parkinson’s disease who did not respond to drugs have been treated with brain cells extracted from aborted foetuses, a practice approved by a committee led by the Rev Dr John Polkinghorne, the prominent ethicist. Gosden said the arguments for the use of aborted foetal cells and therapeutic cloning were similar: “Before you have a disease, it is easy to say, ‘I would not use cells derived from a foetus’, but if you suffer from that disease, and that is your only hope, your approach can be quite different.” 1. What is the new form of cloning discussed in the passage? What is the purpose of such cloning? 2. Summarise the different views on embryo cloning discussed in the passage. 3. Explain the statement “All it takes now is financial investment.” in para. 6. 4. What is the significance of the discovery of embryonic stem cells?
