Dr Richard Seed, one of the leading supporters of human cloning technology, suggests that it may someday be possible to completely change the aging process because of what we learn from cloning. Scientists believe that they may be able to treat heart attack victims by cloning their healthy heart cells and injecting them into the areas of the heart that have been damaged. 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 Alzheimer’s disease, Parkinson’s 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.-1-1．According to Dr Richard Seed, we can use cloning technology to ________.A．produce more animalsB．make people live happilyC．make people look youngerD．cure people of many diseases2．We can learn from the passage that ________.A．cloning has already been used to treat heart diseaseB．we can treat a man’s heart disease by cloning heartsC．most people in industrial countries suffer from heart diseaseD．more people die of heart disease than of other diseases in the US3．What is the main idea of the last paragraph?A．With cloning infertile couples could have children.B．Treatment of infertility is not successful.C．Infertile couples suffer a lot physically and mentally.D．It is difficult for couples to have more children now.4．If a patient is treated with an organ cloned from his own stem cells, ________.A．he will suffer from heart failureB．he is more likely to develop other diseasesC．he won’t be likely to catch other diseasesD．his immune system won’t reject the new organBShirley is looking for work. She is nervous and feels unprepared. After beingat home with her kids for fourteen years, she’s decided it’s time to work againoutside her home. I know she’ll be a great colleague wherever she works but I alsoknow she is nervous. So here are some tips：First impressions are important as everybody says. If you like the person withinthe first nine minutes of your first meeting, it is likely that the sense of a “goodfit” will endure for a long time.Don’t buy fancy new clothes. Dress in a way that doesn’t 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 wantto be sure you’ll work on your own without being fearful or asking for permissionfor 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. Don’t play with yourhair or your fingernails or anything that shows nervousness.-2-If you don’t know something, don’t pretend you do, but tell them you are eagerto learn it. Saying “No, I’ve never done that” or “No, I have no experience”won’t help your case. Instead, say “That’s something I’ve been fascinated by butnever had a chance to deal with before” or “I’m a quick learner, and if somebodywill give me points I’ll 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 makeit enthusiastic. Don’t call the office to see how you did.5．From Paragraph 1, we learn that Shirley________.A．has never worked beforeB．hasn’t worked for a long timeC．doesn’t want to workD．won’t be a good colleague6 ． The underlined word “endure” in Paragraph 2 is similar in meaning to“________”．A．lastB．improveC．disappearD．agree7．What should you do when you don’t know something in an interview?A．Pretend to know a lot about it.B．Think about it for a while.C．Admit it and say you want to know more about it.D．Say sorry to the interviewers and ask for the right answer.8．After the interview, you should ________.A．express thanks soon afterwards B．call the office to see how you didC．wait without doing anything D．send a telegram immediatelyCLooking back on my childhood, I am convinced that naturalists are born and notmade. Although we were brought up in the same way, my brothers and sisters soonabandoned their pressed flowers and insects. Unlike them, I had no ear for music andlanguages. I was not an early reader and I could not do mental arithmetic.Before World War Ⅰ 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 clearlythe 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 andabove all, the insects.I am a naturalist, not a scientist. I have a strong love of the natural world,-3-and my enthusiasm has led me into various investigations. I love discussing my favoritetopics and enjoy burning the midnight oil reading about other people’s observationsand discoveries.Then something happens that brings these observations together inmy conscious mind. Suddenly you fancy you see the answer to the riddle. Because itall 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 plantworld do not make a scientist: one of the outstanding and essential qualities requiredis selfdiscipline, a quality I lack. A scientist can be made a naturalist. If youcan combine the two, you get the best of both worlds.9．According to the author, a born naturalist should first of all be ________.A．full of ambitionB．selfdisciplinedC．full of enthusiasmD．knowledgeable10．The author says that he is a naturalist rather than a scientist probably becausehe thinks he ________.A．just reads about other people’s observations and discoveriesB．lacks some of the qualities required of scientistC．has a great deal of trouble doing mental arithmeticD．comes up with solutions in most natural ways11．The author can’t remember his relatives clearly because ________.A．he didn’t live very long with themB．he was too young when he lived with themC．the family was extremely largeD．he was fully occupied with observing nature12．Which of the following statements is true?A．The author believes that a born naturalist cannot be a scientist.B．The author read a lot of books about the natural world and oil industry.C．The author’s brothers and sisters were good at music and languages.D．The 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 inbiotechnology (生物技术). With the help of new medicine, the human body will lasta very long time. Death will come mainly from accidents, murder and war. Today’s-4-leading killers, such as heart disease, cancer, and aging itself, will become distantmemories.In discussion of technological changes, the Internet gets most of the attentionthese days. But the change in medicine can be the real technological event of ourtimes. 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, scientistswere sure that the life of cells could not go much beyond l20 years because the basicmaterials of cells, such as those of brain cells, would not last forever. But theupper limits will be broken by new medicine. Sometime between 2050 and 2100, medicinewill have advanced to the point at which every 10 years or so, people will be ableto take medicine to repair their organs. The medicine, made up of the basic buildingmaterials of life, will build new brain cells, heart cells, and so on — in much thesame 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 mostbasic condition of human existence, but many technical problems still must be clearedup on the way to this wonderful future.13．According to the passage, human death is now mainly caused by ________.A．diseases and agingB．accidents and warC．accidents and agingD．heart disease and war14．Humans may live longer in the future because ________.A．heart disease will be far away from usB．human brains can decide the final deathC．the basic materials of cells will last foreverD．human organs can be repaired by new medicine15．We can learn from the passage that ________.A．human life will not last more than 120 years in the futureB．humans have to take medicine to build new skin cells nowC．much needs to be done before humans can have a longer lifeD．we have already solved the technical problems in building new cellsⅡ.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 veryearly in order to catch a bus and get to school by the required time.
