Cloning李仕才***阅读理解。
The Internet plays a big part in human life. We use it for work and entertainment. We can find new recipes on the Internet or advice on staying healthy. We can even use it to learn a new language. We use the Internet to connect with family and friends and stay in touch with issues we care about.The list goes on and on.As far as the Internet being a part of our lives—well, that train has left the station. That expression means there is no going back. If you prefer boating, you can say that ship has sailed.So, there may be no going back to an Internet-free life. But can using the Internet too much be bad for our health?It might be, say researchers.Study results show that teens who spend at least 14 hours a week online were more likely to have high blood pressure.High blood pressure makes your heart and blood vessels work too hard. Over time, this extra strain increases your risk of a heart attack or stroke.High blood pressure can also cause heart and kidney disease. It is also closely linked to some forms of dementia, a brain disease. Dementia is marked by memory disorders, personality changes, and a reduced ability to reason.Let’s introduce something about the study of it.The Henry Ford Hospital in Detroit, Michigan did the study. It involved 335 young people, from 14 to 17 years old. One hundred thirty-four of the teens were described as “heavy Internet users”. Researchers found that out of these 134 teens, 26 had high blood pressure.The researchers say the study is the first to connect heavy web use and high blood pressure. Other research has connected that heavy Internet use with health problems including anxiety, depression and obesity.The lead researcher of the study is Andrea Cassidy-Bushrow. In a statement shes aid, “Using the Internet is part of our daily life but it shouldn’t consume us. ”For the purpose of the study, she explains, teens considered heavy Internet users were online on “average 25 hours a week. ”Ms Cassidy-Bushrow adds that it is important for teens to take “regular breaks from their computers or smartphones” and to do some “kind of physical activity. ”She also suggests that parents limit their children’s use of the Internet to two hours a day, five days a week.【文章大意】互联网如此有用并且融入我们的生活, 但过度使用它, 会导致多种健康问题。

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FI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, Now ApproachesWhile clean energy is increasingly used in our daily life, global warming will continue for some decades after CO2 emissions（排放）peak. So even if emissions were to begin to decrease today, we would still face the chai 1 enge of adapting to climate change. Here T will stress some smarter and more creative examples of climate adaptation.When it comes to adaptation, it is important to understand that cl imate changc is a process・ Weare therefore not talking about adapting to a new standard, but to a constantly shifting set ofconditions- This is why, in part at least, the US National Climate Assessment says that:"There is no 'one-si^e fits all' adaptation. ” Nevertheless, there are some actions that offer much and carry little risk or cost.Around the world, people are adapt ing in surprising ways, especial ly 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 floating1ibraries, schools, and heal th 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 1ives in a mountainous region in In di a, where he is known as the Tee Man. The loss of glaciers （&K 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・ NorpheT 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, 000m3 of water. Climate change is a continuing process, so Norphel' s ice reserves wi11 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.Tncreasing Earths reflectiveness can cool the planet. Tn southern Spain the sudden in crease of greenhouses (which reflect light back to space) has cha nged the warm ing 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-Tn 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 wi 11 restore the 1 ife-giving ice. The outcome is sti 11 far from c 1 ear・ But the World Bank has in eluded 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 i n wester n Victoria. Over five gen erations the land has been too wet for cropp ing. But during the past decade declining rainfall has allowed him to plant highly profitable crops. Farmers in many countries are also adapting like this一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 and 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 carb onpolluti on. After all, if we adapt in that way, we may avoid the need to cha nge 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 chango is chailonging2.What is special with regard to Rezwan" s project?A.The project receives government support.B.Di fferent organizations work wi th 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 warming?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。

Text 1M：Have you tried the fish? It is very tasty.W：As a matter of fact, I don't care for seafood.M：Really? What about the green vegetables?W：I like anything but seafood.Text 2M：I'm going to drop my information science class. I need to get up too early in the morning.W：Is that really the good reason to drop the class, Tony?Text 3M：Animals, including insects, do not have a language like ours. They do not talk to each other in words or sentences. But if we watch them, we can see that they do have ways of communicating.Can you see the rabbits' tail? When rabbits see this white tail moving up and down, they are warning each other to run. They know that there is danger. When a bee has found some food, it goes back to its home. It cannot tell the other bees where the food is by speaking to them, but it does a little dance in the air. This tells the bees where the food is. Some animals say things by making sound. A dog barks, for example when a stranger comes near. A cat purrs when pleased. Some birds make several different sounds, each with its own meaning.Sometimes we human beings speak in the same way. We make sounds like “Oh” or “Ah！” when we are frightened or pleased or when we dr op something on our toes. Of things, actions, feelings or ideas, we are able to give each other all kinds of different expressing. But we have something that no animals have—a large number of words which have the meanings, information in words and sentences, which no other animals can do. No other animals have so wonderful a language as we have.1．核心单词(1)differ (vi.) 不同；相异→difference (n.) 不同；差异→different (adj.) 不同的(2)cast (vt.) 扔；投；掷→cast (过去式/过去分词)(3)object (vi.) 反对；不赞成→objection (n.) 反对；不赞成；异议(4)obtain (vt.) 获得；赢得→obtainable (adj.) 可获得的；可得到的(5)owe (vt.) 欠(账、钱、人情等)；归功于……→owing (adj.) 欠着的；未付的(6)retire (vi.) 退休；离开→retirement (n.) 退休；退职→retired (adj.) 退休的(7)bother (vt.) 打扰 (vi.) 操心 (n.) 烦扰(8)strike (vt.& vi.) 打；撞击；罢工(n.) 罢工→struck (过去式/过去分词)(9)vain (adj.) 虚荣的；自负的；徒劳的(10)resist (vt.) 抵抗；对抗→resistance (n.) 抵抗力；反抗→resistant (adj.) 有抵抗力的2．阅读单词(1)exact (adj.) 精确的；准确的(2)commercial (adj.) 商业的；贸易的(3)undertake (vt.) 着手；从事；承担(4)breakthrough (n.) 突破(5)procedure (n.) 程序；步骤；手续(6)forbid (vt.) 禁止；不准(7)accumulate (vt.& vi.) 积累；聚积(8)assumption (n.) 假定；假想；设想(9)regulation (n.) 规则；规章；法规(10)reasonable (adj.) 合情理的；讲道理的；公道的【即景活用】用括号内所给单词的适当形式填空1．His explanation was not ________(reason), so all of us didn't accept it.答案：reasonable2．From the appearance, we can not tell the ________(differ) between the twins.答案：difference3．After his _______ (retire), he settled down in a remote village.答案：retirement4．Grey decided to move to the countryside and his mother made no ________ (object) to it.答案：objection5．What I want is ________ (exact) this one.答案：exactly6．We can't ________ (undertake) the work for the time being.答案：undertake7．It is difficult ________(obtain) reliable evidence.答案：to obtain8．We are playing a trick on a man who keeps ________(bother) me.答案：bothering9．His own pride ________(forbid) him to ask Tom's help.答案：forbids10．Will they be able ________(resist) the temptation to buy?答案：to resist联想积累1．快速掌握“获得”家族①receive收到，得到(信、命令、请帖等)；接受(欢迎，请愿等)②get获得；赚得；赢得③obtain得到，获得；达到(目的)④acquire获得；招致；学得；养成(习惯等)⑤gain获得；赢得，打胜(战争、官司)⑥be available可以得到的，可以买到的2．巧记合成词①fall down→downfall 垮台②get together→gettogether 聚会③break through→breakthrough 突破④break out→outbreak 爆发1．all_the_time 一直；始终2．pay_off 得到好结果；取得成功；偿清3．cast_down 使失望；使沮丧4．in_favour_of 赞成；支持5．(be) bound to (do) ... 一定或注定(做)……6．strike ... into one's heart 使……刻骨铭心7．from time to time 不时；偶尔8．bring back to life 使复生；使复活9．in vain 白费力气；枉费心机10．in good/poor condition 状况很好/坏；情况很好/坏【即景活用】用所给短语的适当形式填空1．The house is really ________and it would cost too much to repair.答案：in poor condition2．She has succeeded.
