Unit 2 CloningⅠ.阅读理解(2017·阳高县一中月考)Among all the fast growing science and technology, the research of human genes, or biological engineering as people call it, is drawing more and more attention now. Sometimes it is a hot topic discussed by people.The greatest thing that gene technology can do is to cure serious diseases that doctors at present can almost do nothing with, such as cancer and heart disease. Every year, millions of people are murdered by these two killers. And to date, doctors have not found an effective way to cure them. But if the gene technology is applied, not only these two diseases can be cured completely, bringing happiness and more living days to the patients, but also the great amount of money people spend on curing their diseases can be saved, therefore it benefits the economy as well. In addition, human life span (寿命) can be prolonged.Gene technology can help people to give birth to more healthy and clever children. Some families, with the English imperial (皇家的) family being a good example, have hereditary diseases. This means their children will for sure have the family disease, which is a great trouble for these families. In the past, doctors could do nothing about hereditary diseases. But gene technology can solve this problem perfectly. The scientist just need to find the wrong gene and correct it, and a healthy child will be born.Some people are worrying that the gene research can be used to manufacture human beings in large quantities. In the past few years, scientists have succeeded in cloning a sheep, therefore these people predict that human babies would soon be cloned. But I believe cloned babies will not come out in large quantities, for most couples in the world can have babies in a very normal way. Of course, the governments must take care to control gene technology.1．What does “them” in the second paragraph refer to?A．People with cancer or heart disease.B．Millions of people with serious diseases.C．Some diseases doctors can do nothing with.D．The two illnesses of cancer and heart disease.2．What can gene technology do according to paragraph three?A．It can help the English imperial family out.B．It can be used to clone human babies.C．It can help people to give birth of a baby.D．It is likely to treat hereditary diseases.3．What are people worried about according to the passage?A．Human babies may be cloned in a large scale.B．Healthy human babies will soon be cloned.C．Scientists may well find the wrong genes.D．The government may not control gene techs.4．This passage is mainly written to ________.A．show gene technology will benefit peopleB．show gene technology will do harm as wellC．tell that gene technology is a hot topicD．tell that gene technology is growing fast答案与解析基因技术可以帮助生产出更健康更聪明的孩子，可以有助于治愈家庭的遗传病，这表明基因技术将会有益于人类。

Unit 2 CloningPeriod 3 A sample lesson plan for Using Language(THE RETURN OF THE DINOSAURS)IntroductionLanguage is learned to be used in and for communication. So in this period we shall have the students read, listen, write and speak in English, making use of the focused words, collocations, structures and topic ideas covered in this unit. The teacher may take the following steps in teaching: warming up by reading aloud the text on page 11 to the tape；Reading for forms；discussing about extinct animals；listening and talking about cloning and closing by looking and saying.ObjectivesTo help students read the passage THE RETURN OF THE DINOSAURSTo help students to use the language by reading, listening, speaking and writingProcedures1. Warming up by reading aloud the text on page 11 to the tape.Why read aloud? Because reading aloud:•Is great fun, and it benefits our growth as readers and learners.•Nurtures our love of both the written and spoken word.•Gives us a chance to rediscover favorite stories and find new ones.•Helps us develop important language skills that will help us learn to read on our own.2. Reading for formsRead the text THE RETURN OF THE DINOSAURS on page 15: cut/ the sentence into thought groups, blacken the predicates, darken the connectives and underline all the useful collocations.3. Discussing about extinct animalsSome animals have gone for ever. Some animals are endangered. Tigers in Asia are endangered. Now in groups of four make a list of endangered animals and have a discussion of them.Endangered tigerThe tiger lives in the jungles and canebrakes of Asia. Its body markings provide excellent camouflage in long grass.This large carnivore usually hunts at night, spending the greater part of the daylight hours resting in shaded areas to escape the heat. It eats a variety of other creatures, from frogs and turtles, to cattle, monkeys, deer, buffalo, and even the occasional young elephant.Tigers are the largest existing members of the Felidae and are, on average, larger than lions, ranging in weight up to 267 kg.4. Listening and talking about cloningCloning is something which will change the direction of the world development. Now let’s listen to more cloning.Is cloning an organism the same as cloning a gene?You've heard about cloning animals --- sheep, mice, even house pets --- in the news. From time to time, you may have also heard about researchers cloning, or identifying, genes that are responsible for various medicalconditions or traits.What is the difference?Cloning an animal, or any other organism, refers to making an exact genetic copy of that organism. The techniques used to clone organisms are described on this page.Cloning a gene means isolating an exact copy of a single gene from the entire genome of an organism. Usually this involves copying the DNA sequence of that gene into a smaller, more accessible piece of DNA, such as a plasmid. This makes it easier to study the function of the individual gene in the laboratory.Now you may work in pairs to put this listening material into a dialogue.5. Closing by looking and sayingLook at the photos and say something about cloning. What is it? How it done?。
