Heart disease is the number one killer in the US and several other industrialised countries.There has been a breakthrough with human stem cells. Embryonic stem cells can be grown to produce organs to repair or replace damaged ones. Skin for burn victims, brain cells for the brain damaged, hearts, lungs, and kidneys could be produced. By combining this technology with human cloning technology, it may be possible to produce needed organs for suffering people that will be free of rejection by their immune systems. Conditions such as Alzheimers disease, Parkinsons disease, heart failure, and other problems can be cured if human cloning and its technology are not banned.Though current treatments for infertility (不生育) are getting a fair amount of publicity in the news, they, in terms of percentages, are not very successful. Some data shows that current infertility treatments are less than 10 percent successful. Couples go through physically and emotionally painful procedures for a small chance of having children. Many couples run out of time and money without successfully having children. Human cloning could make it possible for many more infertile couples to have children than ever before possible.1According to Dr Richard Seed, we can use cloning technology to _.Aproduce more animalsBmake people live happilyCmake people look younger Dcure people of many diseases2We can learn from the passage that _.Acloning has already been used to treat heart diseaseBwe can treat a mans heart disease by cloning heartsCmost people in industrial countries suffer from heart diseaseDmore people die of heart disease than of other diseases in the US3What is the main idea of the last paragraph?AWith cloning infertile couples could have children.BTreatment of infertility is not successful.CInfertile couples suffer a lot physically and mentally.DIt is difficult for couples to have more children now.4If a patient is treated with an organ cloned from his own stem cells, _.Ahe will suffer from heart failureBhe is more likely to develop other diseasesChe wont be likely to catch other diseasesDhis immune system wont reject the new organBShirley is looking for work. She is nervous and feels unprepared. After being at home with her kids for fourteen years, shes decided its time to work again outside her home. I know shell be a great colleague wherever she works but I also know she is nervous. So here are some tips：First impressions are important as everybody says. If you like the person within the first nine minutes of your first meeting, it is likely that the sense of a “good fit” will endure for a long time.Dont buy fancy new clothes. Dress in a way that doesnt call attention to itself. Black trousers or a black skirt and comfortable shoes are OK.Make sure they know they can count on you to accept responsibilities. They want to be sure youll work on your own without being fearful or asking for permission for every little thing; they want to feel confident about you. If you are not confident, fake(假装) it.Keep your hands in your lap or on the arms of the chair. Dont play with your hair or your fingernails or anything that shows nervousness.If you dont know something, dont pretend you do, but tell them you are eager to learn it. Saying “No, Ive never done that” or “No, I have no experience” wont help your case. Instead, say “Thats something Ive been fascinated by but never had a chance to deal with before” or “Im a quick learner, and if somebody will give me points Ill learn them.”There are some details. Show up early. Bring a newspaper to read while you wait. Laugh when something is funny. Send a thankyou note or email immediately and make it enthusiastic. Dont call the office to see how you did.5From Paragraph 1, we learn that Shirley_.Ahas never worked before Bhasnt worked for a long timeCdoesnt want to work Dwont be a good colleague6The underlined word “endure” in Paragraph 2 is similar in meaning to “_”Alast BimproveCdisappearDagree7What should you do when you dont know something in an interview?APretend to know a lot about it.BThink about it for a while.CAdmit it and say you want to know more about it.DSay sorry to the interviewers and ask for the right answer.8After the interview, you should _.Aexpress thanks soon afterwards Bcall the office to see how you didCwait without doing anything Dsend a telegram immediatelyCLooking back on my childhood, I am convinced that naturalists are born and not made. Although we were brought up in the same way, my brothers and sisters soon abandoned their pressed flowers and insects. Unlike them, I had no ear for music and languages. I was not an early reader and I could not do mental arithmetic.Before World War we spent our summer holidays in Hungary. I have only the dim(模糊的)memory of the house we lived in, of my room and my toys. Nor do I recall clearly the large family of grandparents, aunts, uncles and cousins who gathered next door. But I do have a crystal clear memory of dogs, the farm animals, the local birds and above all, the insects.I am a naturalist, not a scientist. I have a strong love of the natural world, and my enthusiasm has led me into various investigations. I love discussing my favorite topics and enjoy burning the midnight oil reading about other peoples observations and discoveries.Then something happens that brings these observations together in my conscious mind. Suddenly you fancy you see the answer to the riddle. Because it all seems to fit together. This has resulted in my publishing 300 papers and books, which some might honor with the title of scientific research.But curiosity, a keen eye, a good memory and enjoyment of the animal and plant world do not make a scientist: one of the outstanding and essential qualities required is selfdiscipline, a quality I lack. A scientist can be made a naturalist. If you can combine the two, you get the best of both worlds.9According to the author, a born naturalist should first of all be _.Afull of ambition BselfdisciplinedCfull of enthusiasm Dknowledgeable10The author says that he is a naturalist rather than a scientist probably because he thinks he _.Ajust reads about other peoples observations and discoveriesBlacks some of the qualities required of scientistChas a great deal of trouble doing mental arithmeticDcomes up with solutions in most natural ways11The author cant remember his relatives clearly because _.Ahe didnt live very long with themBhe was too young when he lived with themCthe family was extremely largeDhe was fully occupied with observing nature12Which of the following statements is true?AThe author believes that a born naturalist cannot be a scientist.BThe author read a lot of books about the natural world and oil industry.CThe authors brothers and sisters were good at music and languages.DThe author spent a lot of time working on riddles.DWhat will people die of 100 years from now? If you think that is a simple question, you have not been paying attention to the revolution that is taking place in biotechnology (生物技术). With the help of new medicine, the human body will last a very long time. Death will come mainly from accidents, murder and war. Todays leading killers, such as heart disease, cancer, and aging itself, will become distant memories.In discussion of technological changes, the Internet gets most of the attention these days. But the change in medicine can be the real technological event of our times. How long can humans live? Human brains were known to decide the final death. Cells (细胞) are the basic units of all living things, and until recently, scientists were sure that the life of cells could not go much beyond l20 years because the basic materials of cells, such as those of brain cells, would not last forever. But the upper limits will be broken by new medicine. Sometime between 2050 and 2100, medicine will have advanced to the point at which every 10 years or so, people will be able to take medicine to repair their organs. The medicine, made up of the basic building materials of life, will build new brain cells, heart cells, and so on in much the same way our bodies make new skin cells to take the place of old ones.It is exciting to imagine that the advance in technology may be changing the most basic condition of human existence, but many technical problems still must be cleared up on the way to this wonderful future.13According to the passage, human death is now mainly caused by _.Adiseases and aging Baccidents and warCaccidents and aging Dheart disease and war14Humans may live longer in the future because _.Aheart disease will be far away from usBhuman brains can decide the final deathCthe basic materials of cells will last foreverDhuman organs can be repaired by new medicine15We can learn from the passage that _.Ahuman life will not last more than 120 years in the futureBhumans have to take medicine to build new skin cells nowCmuch needs to be done before humans can have a longer lifeDwe have already solved the technical problems in building new cells.任务型阅读Your teen is falling asleep in classTeens have a busy morning schedule as they need to wake up and get moving very early in order to catch a bus and get to school by the required time.
