2020学年高中英语Unit2CloningSectionⅤWriting_辩论性议论文教学案新人教

2022-2021学年高中英语同步教案（4：Unit 2 Cloning人教新课标选修8）The first PeriodStep ⅠRevisionCheck the students’ homework.T: Last class we talked something about cloning. Now, who can show your opinion?S: Let me have a try. In my opinion it is wrong to clone human beings. If my parents decided to have a clone made of me, I would feel very sad and I would never accept the clone as a member of the family or as my friend.T: Good job!Step ⅡWord StudyT: You know it is not enough to recite words. You should also use it often. You must pay more attention to the tenses and voices. For example: The building was restored last year. In this sentence, you must use the words “was” and “restored”. Because the past tense and passive voice are contained in the sentence. Do you understand?S: How can I know the tense and voice?T: You can know it throughout some key words and the meanings of these sentences. Now please open your books and turn to page 13. Look at Learning about Language. First let’s do Ex 1. Complete the fol lowing sentences using suitable words or phrases from the previous sections on page 13.You can look them up in an EE dictionary. Complete the sentences with suitable words in correct forms.Several minutes later, check the answers with the whole class.T: Do you know the meaning of “pretty”?S: It means “piaoliang” in Chinese.T: Can you use another word instead of it in English?S: We can use the words “beautiful” and “lovely”.T: You are right! There are many words that have the same meaning. So when we meet them, we must pay more attention to them. Now let’s look at Ex 2. Rewrite the following sentences using words of the similar meaning to replace the underlined words.Several minutes later, check the answers with the whole class. Then do Ex 3.T: After we can use the words in sentences, we will use it in passages. Now, use the words and phrases below to fill in this passage and then answer my questions.Questions:1. What did Freddy want to do when he grew older?2. What did Freddy want to do when the dream that one could live forever now seemed impossible?T: Who can answer my questions? The first one: What did Freddy want to do when he grew older?S1: He wanted to undertake cloning so that his musical career could continue.T: Very good! What about the second one? S2: He made up his mind to enjoy his singing and accumulate many happy experiences so that when he retired he would be able to look back on his life with a great pleasure.T: Good job!Step ⅢRole-play (Ex 4)T: Now, read the questions and answers and underline the words in the answers identical with those in the questions. Then role play your dialogues. Who wants to have a try with your pair?S1: Let me have a try.A sample dialogue:S1: Excuse me, can I ask you some questions?S2: Sure!S1: What is your point of view about human cloning?S2: My opinion is that human cloning should be forbidden.S1: How can you prove a clone is authentic?S2: A real clone should be identical to its original parent, from whom the cell was taken.…T: Good job! (To all the students) You should practice more after class.Step ⅣGrammarT: Do you know the appositive clauses? Please pick out three more examples from the reading passage.Sample answers:The fact is that they are natural clones of each other.The whole scientific would follow the progress of the first successful clone, Dolly the sheep.Altogether Dolly lived for six years, half the length of the life of the original sheep.T: Now let me explain something about the appositive clauses. The appositive clause is a clause used as an appositive. The clause is an explanation to the noun before. The appositive clause belongs to noun clauses. Most of the appositive clauses may be introduced by the conjunction that. A content clause is frequently in apposition with such nouns as fact, news, idea, thought, question, reply, report, remark, hope, belief, suggestion etc.Some examples:Nobody shares my belief that he was mad.My suggestion that he was mad was not accepted.They are familiar with the opinion that all matter consists of atoms.Where did you get the idea that I could not come?We haven’t yet settled the question where we are going to spend our summer vacation.The suggestion came from the chairman that the new rule should be adopted.T: The words the fact are often inserted in front of an object clause when the clause cannot be conveniently。

Give the reasons.can cause much troubles: such as moral questions.using nuclear transfer as of today.T: Good job! Yes, if we our human beings use the scientific technology properly it can bring many advantages to us! T: Whatever the reasons, the new cloning technologies have sparked many ethical debates among scientists, politicians and the general public. Several governments have considered or enacted legislation to slow down, limit or ban cloning experiments outright. It is clear that cloning will be a part of our lives in the future, but the course of this technology has yet to be determined. Cloning could cause birth defects, but it’s not going to change society. In the absence of any legislation or regulation, cloning attempts will quietly continue. Eventually, cloning will succeed (if it hasn’t happened already), and humankind will have taken another step down the road of biological engineering. You should study hard today, and you will be able to face this difficult problem and know how to deal with it.Step V HomeworkAsk the students to do the following.1. Complete the exercises on page 13.2. Recite the key sentences in the text.3. What is Cloning? You might not believe it, but there are human clones among us right now. Have you ever wished you could have a clone of yourself to do homework while you hit the skate park or went out with your friends? Imagine if you could really do that. Where would you start?Teaching reflection。
