⾼考英语⼀轮复习话题37克隆（Unit2Cloning）新⼈教版选修8话题37 克隆（Unit 2 Cloning）晨读背诵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.Scientists have been cloning animals for many years. In 1952, the first animal, a tadpole, was cloned. Before the creation of Dolly, the first mammal cloned from the cell of an adult animal, clones were created from embryonic cells. Since Dolly, researchers have cloned a number of large and small animals including sheep, goats, cows, mice, pigs ,cats, rabbits, and a gaur. All these clones were created using nuclear transfer technology.汉语⼤意：当媒体报道的克隆的消息，他们通常所说的只有⼀种称为⽣殖性克隆的类型。

新课标人教版选修八Unit 2 Cloning教案

Unit 2 CtoningThe First Period Warming up and Reading Teaching goals1.Enable the students to describe cloning: What is theadvantages of cloning?2.Help the students analyze the writing techniques of thearticle.Teaching procedures Step I Warming up一：You can imagine how rapidly the modem science and technology develop. I think most of you must know something about space traveling, submarine exploration, robot, maglev train, gene engineering etc. But in recent years, a hot topic, cloning is often mentioned, especially when the cloning Dolly the sheep appeared. You may have first heard of cloning when Dolly the Sheep showed up on the scene in 1997. Cloning technologies have been around for much longer than Dolly, though.First things first, what is cloning and a clone? The dictionary says cloning is the technique of producing a genetically identical duplicate of an organism. A clone is said to be all descendants derived asexually from a single individual, as by cuttings, bulbs, by fission, by mitosis, or by parthenogenesis reproduction. In fact, in our daily life, this happens often. For example, gardeners take cuttings from growing plants to make new ones. You often see that your mother picks a small branch from a growing plant to make a new one. If she likes this kind of flowers, she can do cloning. Cloning also happens in animals or human beings when twins identical in sex and appearance are produced from thesame original egg.Discussion 1. Do you want to be cloned or not? Why?2.Can you tell me the advantages of cloning?3.And what is the disadvantage?二:Look at picturesLook at the pictures and discuss which ones are natural clones and which ones are man 一made. Then explain how they differ.Step II Pre-reading(Before 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.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?Suggested answers:1.It is a way of making an exact copy of another animal and plant.2.This happens in plants when gardeners take cuttings from growing plants to make new ones, and when small parts of a plant are taken and gown in a laboratory. Italso happens in animals when twins identical in sex and appearance are produced from the same original egg.3.It can help cure disease and can help couples who have no baby to bear a new baby.4.There may be more bad people like Hitler.5.In my opinion, I do not agree, for it may cause many moral problems.6.No. Because cloned human has the same quality as the real human, natural born baby's quality is higher than his parents.7.No. The cloned baby also has the disease.Step III Fast- readingHave you not the answers of your questions? Now please skim the passage fast to obtain a general understanding of the whole passage into several parts and find out the main idea of each part.Show the following.Para. 1 Cloning is a way of making an exact copy of another animal and plant.Para. 2 Cloning has two major uses.Para. 3 The problems of Dolly.Para. 4 The effect of Dolly.Para. 5 It is forbidden to clone human being.Step IV Careful-reading1.Ask the students to read the passage carefully to finish exercise Ion page 12 in the students, book.2.Check the answers.3.Finish exercise2on page 12 in the students' book.4.Check the answers5.Explanationl.)It is a way of making an exact copy of another animal and plant.全句汉语意思:它是一种精确复制另一个动物或植物的方式。

Unit 2 Cloning李仕才***阅读理解。

Spider(蜘蛛) webs have something in common with guitar strings. The long, thin strings on a guitar can vibrate(振动). They move back and forth, or from side to side. So do webs made by spiders. The lines of silk they produce can carry vibrations. This movement gives the small creature information about what landed on the web.Spiders have eight legs and usually eight eyes. The animals build webs with their own soft, naturallymade silk. And much like playing the strings of a guitar, a spider can send out vibrations across its web over many different frequencies(频率). Spiders catch their food, usually insects in their webs. They make small movements, which spread across their webs. The vibrations can give the spider details about what is caught in the web—maybe a possible mate，or something tasty to eat.Vibrations are not just used to spot what is for dinner. They are also important in courtship(求爱), so lots of males will actually create a very specific kind of musical pattern which the females can use to determine not only that they’re a male, but they’re the right species, and whether they might want to mate with them as well.Spiders make their own vibrations to find out the condition of the webs. By controlling the tightness of the material, they can effectively control how information is getting to them when they hang out in the middle of the web.Spiders have a special ability to shape the physical nature of their selfmade materials and creations. Scientists think that spider silk may have changed over time for this purpose.【解题导语】本文介绍了蜘蛛吐出的蛛丝可以传播不同频率的振动，这些振动让它们知道蜘蛛网上落下了什么东西并且这些振动在求爱中也非常重要。
