精美语篇Cloning is a way of making an exact copy of another animal or plant. Cloningplants is straightforward while cloning animals is a difficult task to undertake.From time to time people suggest that extinct animals should be brought back to life through cloning. Last Friday, we had a discussion about whether we should clone animals.Some are in favour of it. Large quantities of commercial food can be produced. Besides, the extinct animals can be cloned, if their DNA is still in good condition. It can also be used to cure serious illnesses.Others have a strong objection to it. They believe that cloned animals can'tresist some diseases and tend to die earlier. Dolly lived six and a half yearsaltogether, half of the length of the life of the original sheep. Above all, it is bound to disturb the balance of nature.◆高频单词1.differ (vi.) 不同；相异→difference (n.) 不同；差异→different (adj.) 不同的2.exact (adj.) 精确的；准确的→exactly (adv.) 精确地；准确地3.undertake (vt.) 着手；从事；承担→undertook (过去式)→undertaken (过去分词)→ undertaking (n.) 任务；项目；事业4.cast (vt.) 扔；投；掷→cast (过去式/过去分词)5.altogether (adv.) 总共；完全地6.object (vi.) 反对；不赞成→objection (n.) 不赞成；反对；异议7.obtain (vt.) 获得；赢得→obtainable (adj.) 可获得的；可得到的8.moral (adj.) 道德(上)的；伦理的→morally (adv.) 道德上地；伦理上地9.accumulate (vt. & vi.) 积累；聚积→accumulation (n.) 积累；聚积10.shortly (adv.) 立刻；不久11.retire (vi.) 退休；离开→retirement (n.) 退休，退职；退役→retired (adj.) 退休的；离职的12.bother (vt.) 打扰 (vi.) 操心 (n.) 烦扰13.assumption (n.) 假定；设想→assume (vt.) 假定；设想14.regulation (n.) 规则；规章；法规→regular (adj.) 规则的；有规律的→regulate (v.) 控制；管理；调节15.resist (vt.) 抵抗；对抗→resistance (n.) 抵抗力；反抗→resistant (adj.) 有抵抗力的；耐……的16.fairly (adv.) 公平地；相当地→fairness (n.) 公平→fair (adj.) 公平的；适当的；合理的17.reasonable (adj.) 合情理的；讲道理的；公道的→unreasonable (反义词) (adj.) 不合情理的→reason (n.) 理由；原因◆重点短语1.pay_off 得到好结果；取得成功；偿清2.cast_down 使沮丧；使失望3.have_a_great_impact_on 对……有重大影响4.object_to 反对5.in_favor_of 赞成；支持6.owe ... to 把……归功于……7.(be) bound to (do) 一定/注定(做)……8.strike ... into one's heart 使……刻骨铭心9.from time to time 不时；偶尔10.bring ... back to life 使复生；使复活11.in vain 白费力气；枉费心机12.in good/poor condition 状况很好/坏；情况很好/坏◆热点句型1.while 表对比关系，“然而；可是”Cloning plants is straightforward while (然而) cloning animals is very complicated.(教材P11)2.当now，then位于句首，谓语是come，appear等且主语为名词时，句子完全倒装Then_came (传来) the disturbing news that Dolly had become seriously ill.(教材P11～P12)3.The advantage is that ... “其优点是……”，that引导表语从句The_advantage_is_that (优点是) if there is a new illness some of these animals may die, but others will survive and pass on the ability to resist that disease tothe next generation.(教材P15)4.based on ... “建立在……的基础之上”，过去分词短语作状语Based_on (建立在……基础之上) what we know now, you can not clone animals that have been extinct longer than 10,000 years.(教材P15)◆同步训练在空白处填入1个适当的单词或括号内单词的正确形式。

Unit 2 Cloning词句猜测题之句意猜测题(阅读理解)方法指导在阅读理解中,解答猜测句意类题目时要仔细阅读文章,对原句进行语法和句意上的准确分析,做出合理的推理和判断。
典例引领 (2017江苏,D)Old Problem, New ApproachesWhile clean energy is increasingly used in our daily life, global warming will continue for some decades after CO2emissions(排放) peak. So even if emissions were to begin to decrease today, we would still face the challenge of adapting to climate change. Here I will stress some smarter and more creative examples of climate adaptation.When it comes to adaptation, it is important to understand that climate change is a process. We are therefore not talking about adapting to a new standard, but to a constantly shifting set of conditions. This is why, in part at least, the US National Climate Assessment says that: “There is no ‘one-size fits all’ adaptation.”Nevertheless, there are some actions that offer much and carry little risk or cost.Around the world, people are adapting in surprising ways, especially in some poor countries. Floods have become more damaging in Bangladesh in recent decades. Mohammed Rezwan saw opportunity where others saw only disaster. His not-for-profit organization runs 100 river boats that serve as floating libraries, schools, and health clinics, and are equipped with solar panels and other communicating facilities. Rezwan is creating floating connectivity(连接) to replace flooded roads and highways. But he is also working at a far more fundamental level: his staff show people how to make floating gardens and fish ponds to prevent starvation during the wet season.Elsewhere in Asia even more astonishing actions are being taken. Chewang Norphel lives in a mountainous region in India, where he is known as the Ice Man. The loss of glaciers(冰川) there due to global warming represents an enormous threat to agriculture. Without the glaciers, water will arrive in the rivers at times when it can damage crops. Norphel’s inspiration came from seeing the waste of water over winter, when it was not needed. He directedthe wasted water into shallow basins where it froze, and was stored until the spring. His fields of ice supply perfectly timed irrigation(灌溉) water. Having created nine such ice reserves, Norphel calculates that he has stored about 200,000m3of water. Climate change is a continuing process, so Norphel’s ic e reserves will not last forever. Warming will overtake them. But he is providing a few years during which the farmers will, perhaps, be able to find other means of adapting.Increasing Earth’s reflectiveness can cool the planet. In southern Spain the sudd en increase of greenhouses(which reflect light back to space) has changed the warming trend locally, and actually cooled the region. While Spain as a whole is heating up quickly, temperatures near the greenhouses have decreased. This example should act as an inspiration for all cities. By painting buildings white, cities may slow down the warming process.In Peru, local farmers around a mountain with a glacier that has already fallen victim to climate change have begun painting the entire mountain peak white in the hope that the added reflectiveness will restore the life-giving ice. The outcome is still far from clear. But the World Bank has included the project on its list of “100 ideas to save the planet”.More ordinary forms of adaptation are happening everywhere. A friend of mine owns an area of land in western Victoria. Over five generations the land has been too wet for cropping. But during the past decade declining rainfall has allowed him to plant highly profitable crops. Farmers in many countries are also adapting like this—either by growing new produce, or by growing the same things differently. This is common sense. But some suggestions for adapting are not. When the polluting industries argue that we’ve lost the battle to control carbon pollution a nd have no choice but to adapt, it’s a nonsense designed to make the case for business as usual.Human beings will continue to adapt to the changing climate in both ordinary and astonishing ways. But the most sensible form of adaptation is surely to adapt our energy systems to emit less carbon pollution. After all, if we adapt in that way, we may avoid the need to change in so many others.1.The underlined part in Paragraph 2 implies .A.adaptation is an ever-changing processB.the cost of adaptation varies with timeC.global warming affects adaptation formsD.adaptation to climate change is challenging2.What is special with regard to Rezwan’s project?A.The project receives government support.B.Different organizations work with each other.C.His organization makes the best of a bad situation.D.The project connects flooded roads and highways.3.What did the Ice Man do to reduce the effect of global warming?A.Storing ice for future use.B.Protecting the glaciers from melting.C.Changing the irrigation time.D.Postponing the melting of the glaciers.4.What do we learn from the Peru example?A.White paint is usually safe for buildings.B.The global warming trend cannot be stopped.C.This country is heating up too quickly.D.Sunlight reflection may relieve global warming.5.According to the author, polluting industries should .A.adapt to carbon pollutionB.plant highly profitable cropsC.leave carbon emission aloneD.fight against carbon pollution6.What’s the author’s preferred solution to global war ming?A.Setting up a new standard.B.Reducing carbon emission.C.Adapting to climate change.D.Monitoring polluting industries.方法运用[语篇解读] 本文为议论文,题材为环境问题类。

Unit 2 CloningⅠ阅读理解(2018·四川成都诊断)Wouldn’t it be wonderful to travel to a foreign country without having to worry about the headache of communicating in a different language?In a recent article from TheWallStreetJournal, technology policy expert Alec Ross argued that，within a decade or so, we’ll be able to communicate with one another via small earpieces with builtin microphones. That’s because technological progress is extremely rapid.It’s only a matter of time. Indeed, some parents are so convinced that this technology is imminent that they’re wondering if their kids should even learn a second language.It’s true that an increase in the quantity and accuracy of the data loaded into computers will make them cleverer at transla ting “No es bueno dormir mucho” as “It’s not good to sleep too much”. Replacing a word with its equivalent(对应词) in the target language is actually the “easy part” of a translator’s job.But even this seems to be a discouraging task for computers.It’s so difficult for computers because translation doesn’t —or shouldn’t—involve simply translating words, sentences or paragraphs. Rather, it’s about translating meaning. And in order to infer meaning from a specific expression, humans have to interpret a mass of information at the same time.Think about all the related clues that go into understanding an expression: volume, gesture, situation, and even your culture. All are likely to convey as much meaning as the words you use.Therefore ，we should be very skeptical of a machine that is unable to interpret the world around us. If people from different cultures can offend each other without realizing it, how can we expect a machine to do better? Unless engineers actually find a way to breathe a soul into a computer, undoubtedly when it comes to conveying and interpreting meaning using a natural language, a machine will never fully take our place.【解题导语】技术专家说随着技术的进步，即时翻译机器将在大约十年内出现在市场上。
