[基础巩固]单句语法填空1．Our strength is from many sources，but most of all，we owe our success to the creativity of our people.2．The students were_forbidden (forbid)，unless they had special passes，to leave the base.3．Do you know any differences (differ) between British English and American English?4．The new clothes in the shop are so beautiful that Anna can't resist taking (take) a closer look at them.5．The visitors were_struck (strike) by the beauty of the tourist area as soon as they saw it.6．His suggestion that we should solve the problem step by step is reasonable.7．Don't let yourself be_cast (cast) down by a small failure in the experiment，try again.8．He is working so hard that he is bound to_win (win) the first prize.9．In ancient times，people believed that they could be brought back to life.10．All efforts will be in vain if we can't learn English by practicing repeatedly.[能力提升]Ⅰ.阅读理解A deal has been signed to turn by products from a Scottish distillery (酿酒厂) into fuel for cars.In what is declared to be a world first, the Tullibardine distillery in Perthshire has linked up with a spin out company from Napier University in Edinburgh.They plan to use bacteria to feed on the “leftovers” from the whisky (威士忌酒) making process.This will produce butanol which can be used to fuel vehicles.More than 90% of the stuff that comes out of a whisky distillery is not whisky.It is leftovers like draff and pot ales (酒糟)—both produced in the early stages of the process.They are high in sugar and are currently used for things like fertiliser and cattle feed.Napier University's Biofuel Research Centre (BRC) has already shown that the right bacteria can feed on those by products to produce butanol—a direct replacement for vehicle fuel.Now the spin out company, Celtic Renewables, and independent whisky producer Tullibardine have signed an agreement.Together they will apply the process to thousands of tons of the distillery's leftovers.Professor Martin Tangney, founder of Celtic Renewables, said “Our partnership with Tullibardine is an important step in the development of a business which combines two important Scottish industries—whisky and renewables.This project shows that creative use of existing technologies can utilize resources on our doorstep to benefit both the environment and the economy.”Douglas Ross, managing director of Tullibardine, which spends ￡250,000 disposing of its by products every year, said “We are delighted to be partnering Celtic Renewables in this creative business, the obvious benefits of which are environmental.It takes a cost to us and turns it into something that has social as well as commercial value.”The project is being supported by a grant (拨款) from the Scottish government's Zero Waste Scotland initiative.Celtic Renewables said it eventually aimed to build a processing plant in Scotland, with the hope of building an industry that could be worth ￡60 million a year.[语篇导读] 本文讲述的是一种新型的环保技术：用酿酒厂里的酒糟来代替汽油。

选修八Unit_2 Cloning原文翻译
Unit 2 克隆：他将把我们引向何方？
克隆一直与我们同在，而如今它还要坚持下去。这是一种用来生产与原型完全相同的动植物的方法。当园艺师从生长的植物上剪下枝条来培植新植物时，就会产生这种现象。这种现象也发生在动物身上，从同一个原生卵子产生性别和相貌相同的双胞胎也是克隆。实际上，这些都是自然克隆现象。
On the one hand, the whole scientific world followed the progress of the first successful clone, Dolly the sheep. The fact that she seemed to develop normally was very encouraging. Then came the disturbing news that Dolly had become seriously ill. Cloning scientists were cast down to find that Dolly's illnesses were more appropriate to a much older animal. Altogether Dolly lived six and a half years, half the length of the life of the original sheep. Sadly the same arbitrary fate affected other species, such as cloned mice. The questions that concerned all scientists were: "Would this be a major difficulty for all cloned animals? Would it happen forever? Could it be solved if corrections were made in their research procedure?"
人教版高中英语选修8练习：Unit 2 Cloning (含解析)
Unit 2 Cloning[导语] 从1998年中国科学院动物研究所首席科学家、动物克隆与受精生物学学科带头人陈大元首次正式提出克隆大熊猫到现在，整整20年过去了，陈老仍然执着于此。
然而保护大熊猫，究竟要不要通过克隆的方式呢？China has been exploring every possible means of saving giant pandas，one of the world's most endangered species，from becoming extinct，even if it means resorting to(诉诸) cloning them.Chen Dayuan，a senior scientist who specializes in cloning at the Institute of Zoology in the Chinese Academy of Sciences，introduced the idea of performing cloning techniques on giant pandas in 1998.Using initial funding of 100，000 yuan，Chen successfully produced blastocysts(胚泡) by transplanting the somatic nucleus from sample pandas into the egg cells of rabbits.“Those who are against cloning have made their voices heard throughout the research project on cloning giant pandas.Some people believe cloning goes against nature，but it is actually a pioneering technology.If successful，it isa way to save endangered animals，”Chen said.Some scientists take a different view.“While I agree that research on cloning is meaningful，it is inappropriate to use giant pandas in this type of experiment.The number of pandas is limited and human beings have yet to master knowledge about pandas' pregnancy.Cloning would do little to save the species，”said Wang Dajun，a researcher at the School of Life Sciences，Peking University.In response，Chen said that he would continue his research.[词海拾贝]1．endangered adj.快要绝种的2．technique n．技巧，手法3．transplant v．移植4．pregnancy n．怀孕[问题思考]1．Do you think pandas

A big 28 which had been following the taxi stopped, too. The taxi driver was now 29 at the corner looking up 30 the sky and the truck driver got out and 31 him. A number of cars behind them were 32 to stop as well and a large crowd of people had 33 at the corner.The cause of all this 34 was a very strange noise.

Now middle-aged Americans may not keep in touch with old people until they are old themselves.That's because we group people by age. We put our three-year-olds together in day-care centers, our 13-year-olds in schools and sport activities, and our 80-year-olds in senior citizen homes. Why?We live far away from the old for many reasons. Young people sometimes avoid the old to get rid of fears of becoming old and dying. It is much harder to watch someone we love disappear before our eyes. Sometimes it’s got hard that we stay away from the people who need us the most.Fortunately, some of us have found our way to the old. And we have discovered that they often save the young.A reporter moved her family into a block filled with old people. At first her children were disappointed. But the reporter made banana bread for the neighbors and had her children send it and visit them. Soon the children had many new friends, with whom they shared food, stories and projects. "My children have never been lonely, "the reporter said.The young, in turn, save the old. Once I was in a rest home (an organization whereold people are cared for) when a visitor showed up with a baby, she was immediately surrounded. People who hadn't gotten out of bed in a week suddenly were ringing for a wheelchair. Even those who had seemed asleep woke up to watch the child. Babies have an astonishing power to comfort and cure.Grandparents are a special case. They give their grandchildren a feeling of security and continuity. As my husband put it "My grandparents gave me a deep sense that things would turn out right in the end." Grandchildren speak of attention they don't get from worried parents. "My parents were always telling me to hurry up, and my grandparents told me to slow down," one friend said. A teacher told me she can tell which pupils have relationships with grandparents: they are quieter, calmer and more trusting.46. Now in an American family, people can find that___________.A. children never live with their parentsB. not all working people live with their parentsC. old people are supported by their grandchildrenD. grandchildren are supported by their grandparents47. Seeing a baby, the old people got excited because _______.A. they had never seen a baby beforeB. the baby was clever and beautifulC. the baby brought them the image of lifeD. the baby's mother would take care of them48. Why are some children quieter, calmer and more trusting ?A. Because they have relationships with their grandparents.B. Because their worried parents ask them to act like that.C . Because they have nothing to worry about.D. Because their teachers ask them to act like that.49. Which of the following can show the fact that the old often save the young?A. The old can become friends of the children and the children may not feel lonely.B. The old get excited when they see a baby. 高@考☆资&源*网C. The old can cure the young when they are sick.D. Babies have an astonishing power to comfort and cure.B篇The other day I heard a few local musicians talking:"I hate all the pianos in this town and I hate that rubbish they play on the radio. They cannot even understand rhythm (韵律).""Nobody wants to pay musicians anything. I’m sick of all the people who want you to play without paying you."One younger musician said, "There are several clubs who want me to play for a few nights a month, and I’m trying to find other places to play. I’m also planning to join in several summer festivals this year."I really liked what the younger musician said so I made friends with him. Attitudes are important. Whether they’re positive (积极的) or negative (消极的), they’re all rubbing off on you. If you’re around people who are always complaining or blaming (责备) others, it is possible that you will start doing the same as well. If you spend lots of time with people wh o don’t support (支持) your dreams, it is time to take a look at the people you call "friends".There is an easy exercise you can try. Make a list of the people who you often stay with, and simply stop spending time with the negative ones on your list. Set a new standard for yourself and don’t become friends with people who fall below that standard.Of course, this exercise is entirely different from making friends only for the good of oneself. We really should try to help and spend time with those who are working towards a goal or dream.50.The musicians’ conversation at the beginning is there to show that ______.A. musicians’ living conditions are not goodB. people in that town have poor taste in musicC. young people are more likely to succeedD. different people have different attitudes51.The underlined part "they’re all rubbing off on you" in Paragraph 6 means ______.A. they’ll push you aheadB. they’ll help you realize your dreamsC. they’ll keep you from moving onD. they’ll have an influence (影响) on you52.By doing the exercise mentioned in Paragraph 7, you can ______.A. improve your ability to make friendsB. make the right kind of friendsC. develop a better relationship with your friendsD. make some new friends with the same interests as you53. We can get the following information from the passage EXCEPT ______.A. the younger musician is a positive person and would be a good friendB. one should avoid (防止) making friends with people who have lots of difficultiesC. the exercise can help you keep close to really helpful friendsD. one will start complaining if one spends too much time with negative people .26—45 CCADD CBDDD CDBDC BBDDC 46-53 BCAA DDCB。
