Unit 2 Cloning————[单元主题语境]———人与社会之科技发展与信息技术创新，科学精神，信息安全(2018·高考某某卷)话题：3D食物打印词数：383 难度：★★★★There's a new frontier in 3D printing that's beginning to e into focus: food. Recent development has made possible machines that print, cook, and serve foods on a mass scale. And the industry isn't stopping there.Food productionWith a 3D printer, a cook can print plicated chocolate sculptures and beautiful pieces for decoration on a wedding cake. Not everybody can do that—it takes years of experience, but a printer makes it easy. A restaurant in Spain uses a Foodini to “recreate forms and pieces”of food that are “exactly the same，”freeing cooks to plete other tasks. In another restaurant, all of the dishes and desserts it serves are 3Dprinted, rather than farm to table.Sustainability (可持续性)The global population is expected to grow to 9.6 billion by 2050, and some analysts estimate that food production will need to be raised by 50 percent to maintain current levels. Sustainability is being a necessity. 3D food printing could probably contribute to the solution. Some experts believe printers could usehydrocolloids (水解胶体) from plentiful renewables like algae (藻类) and grass to replace the familiar ingredients (烹饪原料).3D printing can reduce fuel use and emissions. Grocery stores of the future might stock “food”that lasts years on end, freeing up shelf space and reducing transportation and storage requirements.NutritionFuture 3D food printers could make processed food healthier. Hod Lipson, a professor at Columbia University, said, “Food printing could allow consumers to print food with customized nutritional content, like vitamins. So instead of eating a piece of yesterday's bread from the supermarket, you'd eat something baked just for you on demand.”ChallengesDespite recent advancements in 3D food printing, the industry has many challenges to overe. Currently, most ingredients must be changed to a paste (糊状物) before a printer can use them, and the printing process is quite timeconsuming, because ingredients interact with each other in very plex ways. On top of that, most of the 3D food printers now are restricted to dry ingredients, because meat and milk products may easily go bad. Some experts are skeptical about 3D food printers, believing they are better suited for fast food restaurants than homes and highend restaurants.[语篇解读] 本文是一篇科普说明文。

Unit 2 Cloning请根据以下内容，使用5个规范的句子说明克隆的利与弊。
优点：克隆可以复制东西——很多人想拥有的同样的一个东西；克隆可以防止世界上的物种消失；克隆可以使我们以旧换新；克隆可以推动我们的技术；克隆也可以使许多没有生育能力的人实现生育梦想。
缺点：克隆可能会与道德发生冲突；克隆将降低原来生命的价值。
参考词汇：复制 copy; 物种消失 the disappearance of living things; 没有生育能力的人 people unable to have children【写作要求】必须使用5个句子介绍全部所给的内容。
In modern times, scientists can copy or clone the things which many people want to own. As we know, cloning has some advantages. It can prevent from the disappearance of living things in the world and enable us to get a new one of the old. Besides, with the cloning technology, people unable to have children can realize their dreams. But cloning has its disadvantages which result in reducing the value of the original one and causing conflicts between morality.1. vi. 不同；相异2. adj. 准确的；精确的3. vt. 着手；从事；承担4. n. 突破5. vt. 扔；投；掷6. vi. 不赞成；反对7. vt. 获得；赢得____________________ ________________________________________________________________________________________________________________________differexactundertakebreakthroughcastobjectobtain8. vt. 禁止；不准9. vt. 积累；聚积10. vt. 欠；归功于……11. vi. 退休；离开12. vt. 打扰 vi. 操心 n. 烦扰13. n. 假定；设想14. v. 打；撞击；罢工 n. 罢工____________________________________________________________ ________________________________________ ____________________ ____________________ forbidaccumulateoweretirebotherassumptionstrike15. adj. 虚荣的；自负的；徒劳的16. vt. 抵抗；对抗17. n. 缺点；不利条件18. adv. 仅；只；不过19. adj. 不能的；不会的20. adj. 合情理的；讲道理的；公道的________________________________________ ________________________________________________________________________________vainresistdrawbackmerelyunablereasonable1. 沮丧；不愉快2. 白费力气；枉费心机3. 赞成；支持4. 一定或注定(做)……5. 使……刻骨铭心6. 不时；偶尔7. 使复生；使复活____________________________________________________________ ____________________ ____________________ ____________________ ____________________cast downin vainin favor of(be) bound to (do)…strike…into one's heartfrom time to timebring back to lifepay offhave an impact onin good/ poor condition8. 偿清；取得成功9. 对……有影响10. 状况很好(坏)；情况很好(坏)____________________________________________________________1.The fact ________ she seemed to develop normally was very encouraging.2.Then came the disturbing news ________ Dolly had become seriously ill.3.Cloning scientists were cast down to find ________ Dolly's illnesses were more appropriate toa much older animal.thatthatthat4.However, scientists still wonder ________ cloning will help or harm us and ________ it is leading us.5.________ (base) on what we know now, you cannot clone animals ________ have been extinct longer than 10,000 years.wherewhetherBasedthat1. differ vi. 不同，相异I differ with the teacher on several matters of opinions.我与老师在几个事情的意见上不一致。

高二英语选修8学案：语法解读Unit2Cloning含解析
四、语法解读名词性从句之二同位语从句在复合句中充当同位语的从句称为同位语从句。
同位语从句是名词性从句（主语从句、表语从句、宾语从句、同位语从句)中的主要从句之一，它是中学英语学习的重点语法项目，也是历年高考英语试题中的重要考点。
在使用同位语从句时，应注意以下五个方面：（一）同位语从句在句中的位置1。
一般情况下同位语从句跟在某些名词(如news,idea，fact，promise,hope，message等）的后面，用以说明该名词所表示的具体内容。
如:The news that our women volleyball team had won the championship encouraged us all greatly。
I’ve come from Mr Wang with a message that he won't be able to see you off this afternoon。
2.有时同位语从句可以不紧跟在它所说明的名词后,而被别的词语隔开，在语法上叫做分隔式同位语从句。
如：The thought came to her that maybe she had left the door open when she left home。
The story goes that he failed in the college entrance examinations again.（二）同位语从句前名词的数同位语从句前的名词通常用单数形式，并且往往有限定词加以修饰（word除外）。
如：Where did you get the idea that I could not come？Give me your promise that you will come to our party this evening.Word came that China launched its second manned spaceship on Oct.12,（2005.（三）同位语从句连接词的选用引导同位语从句的词通常有连词代词that，who;连词whether；连接副词how,when where等。

选修8 Unit 2 Cloning克隆晨读·记忆Be Careful about CloningAfter a series of initial experiments and corrections, the scientist’s hard work paid off when the twin clone turkeys were hatched with normal feather and claws. 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 toresist 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.Shortlyafterwards, 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.”谨慎对待克隆在最初一系列的实验和修正之后，科学家的辛苦工作终于取得了成功，一对双生的克隆火鸡孵化出来，羽毛和爪子都很正常。
这一突破或许能让人们使他们喜爱的宠物死而复生。
然而，使他不时地烦恼的是，因为它们无法抵抗疾病，使得它们的健康状况极差。
这个缺点让他很沮丧。
仅仅过了两个星期，克隆体和母体都死亡了，这使他内心里充满了挫折，他也因此在达到自己目标前就退休了，并选择加入歌剧合唱团来减轻消沉的感觉。
之后不久，媒体就因为道德问题而发表了反对克隆的保守论点，并且建议宪法应该包括强制性的法规禁止通过克隆获得商业利益。
当被采访时，科学家盯着天花板上的装饰物思考了一会儿，说：“我不赞成任何任意的假设，但是从事克隆与用面粉制作面包的简单过程确实不大相同。
在我们积累了足够的准确知识前，任何实际操作都是徒劳无功的，注定会失败。
总而言之，更加谨慎地对待克隆是合理的，否则我们或许会误入歧途。
