Unit 2 CloningPart 1 Teaching Design第一部分教课方案Period 2 A sample lesson plan for Learning about Language (Revise the Appositive <words||，phrases and clauses>) IntroductionIn this period students will be first helped by the teacher to discover and learn to use some useful words and collocations|| ， and then to discover and learn to use the following useful structures: the appositive <words||， phrases and clauses>. The following steps of teaching may be taken: warming up by reading aloud to the tape the text CLONING： WHERE IS IT LEADING US?；learning about appositive； building up on your word power ； discovering useful words and collocations ； discovering and distinguishing ； closing down by talking about cloning.ObjectivesTo help students revise the Appositive <words|| ， phrases and clauses>)To help students discover and learn to use some useful words and collocationsTo help students discover and learn to use some useful structuresProcedures1.Warming up by reading aloud to the tape the text CLONING： WHERE IS IT LEADING US?2.Learning about appositiveWhat is an Appositive?An appositive is a noun|| ， noun phrase||， or noun clause which follows a noun or pronoun and renames or describes the noun or pronoun. A simple appositive is an epithet like Alexanderthe Great. Appositives are often set off by commas.Example: We visited the home of Harriet Beecher Stowe|| ， the author of Uncle Tom's Cabin. (The underlined portion is the appositive.)Appositive PhrasesAn appositive phrase is a type of noun phrase that follows the noun or pronoun it modifies andamplifies or restricts its meaning.Our monitor||， a careful reader and outspoken critic ||， will examine the article before it is handed to the headmaster. [The italicized phrase is an appositive.]Appositive phrases are similar to relative clauses; to avoid wordiness|| ， relative clauses can often be reduced to appositive phrases.3. Building up on your word powerTo build up on your word power you are to make sentences with the collocations from the text: CLONING ： WHERE IS IT L EADING US? You may try to include as many uses of the Appositive <words|| ， phrases and clauses> as possible.1.This is a way of learning English|| ， the most popular language in the word.2.People in the future will make an exact copy of themselves.3.We may grow human beings in a laboratory in the near future.4.They are identical in sex and appearance.5.This mysterious thing is produced from coals.6.The natural clones of these plants have two major uses||， one for eating||， one forreproduction.7.At all the time|| ， producing commercial quantities of concrete things is difficult.8.We are going on with our research on the cloning of animals.9.The determination and patience of students will be rewarded with a breakthrough in cloning.10.Following the progress of English development we shall come to a conclusion that thisworld language is becoming simpler in sentence structure.4. Discovering useful words and collocations.A collocation is two or more words that often go together. These combinations just sound "right"to native English speakers|| ， who use them all the time.Now you may go to page 13. Finish the four words and collocations exercises in groups of four.5. Discovering and distinguishingTo find out and write down all the examples of the Appositive <words||，phrases and clauses>) you are to read the text Cloning: Where is it leading us?The fact that she seemed to develop normally was very encouraging ．Then came the disturbing news that Dolly had become seriously ill.Altogether Dolly lived for six years||， half the length of the life of the original sheep.Some more examples of the AppositiveMr. Smith|| ， our new teacher||， is very kind to us.Yesterday I met Tom||， a friend of my brother's.He himself told me that his brother John is a world-famous doctor.Yesterday I talked to my English teacher|| ， Mr. James.We Chinese people are brave and hardworking.He is interested in sports||， especially ball games.There are differences between appositive clauses and attributive clauses.●同位语从句只是出此刻belief||， conclusion||， doubt||， fact||， hope||， idea||， knowledge||，law||， message||， news||， notion||， order||， proof||， rumor||， sign||， suggestion||， theory||，thought 等抽象名词的后边 ||，用于进一步说明或解说该名词的内容 ||。

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。
