So teacher should help the students learn more about it. Do this in the way of asking and answering questions.T: When the media report on cloning in the news, they are usually talking about only one type called reproductive cloning. There are different types of cloning however, and cloning technologies can be used for other purposes besides producing the genetic twin of another organism. A basic understanding of the different types of cloning is key to taking an informed stance on current public policy issues and making the best possible personal decisions. The following three types of cloning technologies will be discussed: (1) recombinant DNA technology or DNA cloning, (2) reproductive cloning, and (3) therapeutic cloning.More questions about cloning are given in the appendix. The information above is for reference only. Or you can choose several students and ask them to act out a short play whose main topic is as follows:An old man who was dying left all his fortune to his own son. But the did not know that his son was cloned. So two same young men both claimed that they were the old man’s son. They quarreled and fought with each other; at last they went to the judge. The judge let them check DNA. The result was that their DNA was the same. Now even the judge did not know what to do.In this part the teacher can give the students some advice to act out. According to this play teacher ask the students several questions:1. Do you want to be cloned or not? Why?2. If you are the judge what will you do?3. Can you tell me the advantages of cloning?4. And what is the disadvantage?DiscussionIn this part the students will discuss the relationship between the development of technology and social customs.T: As the technology develops day by day, it has a more and more important influence on the whole society. Technology affects social customs and ethics, sometimes technology may go against the conventional thinking, then comes the problem that whether we should stop the development of research or change the ethics.a lot of our original customs and ethics changed, either because they are out of time or not so scie …Look at picturesT: Look at the pictures and discuss which ones are natural clones and which ones are man – made. Then explain how they differ.Step II Pre-readingBefore class, ask the students to search for some information about this topic. Now show your questions on the screen, and then let them discuss with each other.T: Now please work in pairs and discuss about cloning. Then list the questions you want to find out. Share your list with your partner.Questions about cloning:1. What is a clone?2. How is a clone produced?3. What benefits can humans gain from cloning?4. What problems may arise when humans are cloned?5. Should we clone human?6. Could cloning replace sex as the means of creating new human life?7. Could a parent clone a child who is dying of a terminal illness?After a few minutes.T: Do you have other questions? Volunteer!Step 3.

【关键字】英语Unit 2 CloningⅠ.阅读理解(2017·泉州高三质量检查)When students read articles about scientific discovery，they learn what worked.Scientists present the methods that got the best result.They often show only the results that are significant and important.What they won't show are the mistakes or failures that came first.Yet sometimes those mistakes pointed the way to success.It can take a long time and many experiments to achieve scientific success.Robbin，16，and Annabelle，15，learned that while working this summer in a biochemistry lab at Stony Brook University in New York.What's more，they learned that failure is not necessarily something to fear.“I like the idea of scientific research，”says Robbin.It's the basis for “every lesson you learn in school and understanding everything you see in life”. This summer，Robbin has been working with Lauren，a chemistry student，who is making new drugs to fight harmful bacteria.At first，the tests made Robbin anxious.She worried that she might be making costly mistakes.But Lauren reassured her that finding out what doesn't work is “just part of the learning process”．With time，the teen got comfortable with the idea that every experiment wouldn't succeed.Annabelle also learned a lot about failure and success.She worked with graduate student Agnieszka Gil.“Sometimes I try something and it takes a while for the experiment to run.”This means that finding out whether Annabelle did something wrong can be a stressful waiting game，because “if you did something wrong you need to do it again”．But she's now learning to be patient and not to expect instant success.In science，figuring out why something failed is what may just put them on the road to success.【语篇解读】在阅读科学发现的文章时，人们往往对科学成就过度关心，其实科学成就往往是建立在无数次失败的基础之上的。

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 municating.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 es 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 drop 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)mercial (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.) 规那么；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cast down， in vain， pay off， from time to time， in poor condition， bring back to life1．The house is really ________and it would cost too much to repair.答案：in poor condition2．She has succeeded.

This breakthrough possibly enabled people to bring their adored pets back to life. However, it bothered him from time to time that their health was in poor condition because they were unable to resist illnesses. This drawback cast him down. Merely 2 weeks later, the clones and their carrier died, which struck frustration into his heart. He retired before he attained his ambition and became a member of an opera chorus to relieve his depression.Shortly afterwards, the media published a conservative argument objecting to cloning owing to moral problems, and suggested the constitution include compulsory regulations to forbid obtaining commercial profits from cloning.When interviewed, the scientist stared at the decorations on the ceiling, thinking for a while, and then said, “I’m not in favour of any arbitrary assumption, but undertaking cloning does differ from the straightforward procedure of making loafs out of flour. Until we accumulate enough exact knowledge, any practice is in vain and is bound to fail. Altogether, being more careful is reasonable or we may walk into a side road.”慎重对待克隆在最初一系列的实验和修正之后，科学家的辛劳工作终于取得了成功，一对双生的克隆火鸡孵化出来，羽毛和爪子都专门正常。

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.

精美语篇Cloning is a way of making an exact copy of another animal or plant. Cloning plants 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 cloneanimals.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't resist some diseases and tend to die earlier. Dolly lived six and a half years altogether, 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.) 积存；聚积→accumulation (n.) 积存；聚积10.shortly (adv.) 赶忙；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.) 打搅 (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.) 操纵；治理；调剂15.resist (vt.) 抗击；对抗→resistance (n.) 抗击力；抵抗→resistant (adj.) 有抗击力的；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→reaso n (n.) 理由；缘故◆重点短语1.pay_off 得到好结果；取得成功；偿清2.cast_down 使沮丧；使败兴3.have_a_great_impact_on 对……有重大阻碍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；偶然10.bring ... back to life 使复生；使复活11.in vain 白费劲气；枉费心机12.in good/poor condition 状况专门好/坏；情形专门好/坏◆热点句型1.while 表对比关系，“然而；但是”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 to the 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。
