2.T: From the analysis of the sentence patterns, can you tell me what types of noun clauses are there.
S:Noun clauses are classified as subject clause, object clause, predicative clause and appositive clause.
It happened that…碰巧…
It appears that…似乎…
4It is＋过去分词＋从句
It is reported that…据报道…
It has been proved that…已证实…
It is said that…据说…
it作形式主语和it引导强调句的比较
it作形式主语代替主语从句,主要是为了平衡句子结构,主语从句的连接词有变化。而it引导的强调句则是对句子某一部分进行强调,无论强调的是什么成分,都可用连词that。被强调部分指人是也可用who/whom。例如:

名词性从句
【概念与分类】在句子中起名词作用的句子叫名词性从句。名词性从句的功能相当于名词词组,它在复合句中能担任主语、宾语、表语、同位语、介词宾语等,因此根据它在句中不同的语法功能,名词从句又可分为主语从句、宾语从句、表语从句和同位语从句。

人教版高中英语选修八第一单元语法课教学设计.docx
人教版高中英语选修八第一单元语法课教学设计一、整体设计思路、指导依据说明指导依据：语言学家认为，语法是语言发生作用的框架, 语法能力是掌握语言形式的知识体系，是语言实践能力的前提。
语言学家乔姆斯基(Noam Chomsky)的转换生成语法理论认为语言不仅是一套习惯的体系，更是受规则支配的体系。
交际教学法的主要奠基人威尔金斯(W订kins)在《第二语言学习与教学》一书中明确指出：语法是学习的中心，是保证表意的必须手段，又是规则和知识系统。
语法知识可规范学生的语言知识，使学生在学习语言的过程中，不仅具有交际能力，且能提高系统的语言知识能力。
在高中英语新课程标准的指导下，教师应树立全新的教学观念，要以学生为主体，从而激发学生深层的和持久的学习兴趣。
语法教学的实质是在语言教学的过程中指导学生对语言现象进行分析和归类，掌握其规律，训练学生正确和熟练地运用语言。
另外在语法的巩固练习上也应该让学生积极参与进来，循序渐进的指导学生在实践中自主、合作地学习。
侧重提高学生对语言的感受和初步用英语听、说、读、写的能力，同时也应该不断的鼓励和赞美学生，让他们体会到成功的喜悦。
设计思路：语法教学本身并非目的，而是为学生掌握和运用语言服务的。
因此，本次教学不能是“满堂灌”，给学生造成“繁、难、杂”印象。
学习语法最好的方法是在“用” 中学。
因为本节课为语法复习课，学生对所复习内容已经比较熟悉，所以本节课的教学模式可归纳为“再呈现一一再发现一一再归纳一一实践一一活用”。
首先让学生再次发现语法现象，并帮助他们重新归纳出语法结构形式与功能。
最终使学生真正掌握并能活用所学语法结构并应用到实际的读、说、写中去，达到语言学习的最终目的。
具体授课过程缩略图：（见图1）二、教学背景分析教学背景分析：本单元的语法为名词性从句，因为之前名词性从句是连贯初中到高中的英语重点语法概念，也是历年高考英语考试的一个考查热点。
纵观历年高考英语，我们就能发现：英语高考对于名词性从句考查的重点就是名词性从句的引导词的选择、引导词之间的区别、名词性从句的陈述语序以及主从句时态一致性原则等。

Then explain how they differ.S: I think the twins are natural clones and the Dolly sheep is man-made.T: You are right! Can you explain how they differ?S: The twins were born at the same time, but the Dolly sheep is man-made.T: Anything else? Who want have a try?S: I think the identical dog is man-made.T: Good job!Step Ⅱ Pre-readingBefore 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.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?Suggest 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. It also 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 While-readingGet the students to comprehend the passage quickly and accurately and meanwhile help the students form a good habit of reading.divide 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 Post-readingAsk the students to read the passage again to finish three tasks.T: Now let’s listen to the tape. While listening, pay more attention to the correct pronunciation and tone. Then read the text by yourselves to get the answers to the three tasks. You can work in groups.T: First, what are the problems or dangers of cloning?S: Let me have a try! First, the cloned animals have the same illness of the old animals and the same goes with the other species. Second, the cloned animals have short life and can cause moral questions.T: You are right! And what are the advantages of cloning?S: I know! Firstly, gardeners use it all the time to produce commercial quantities of plants. Secondly, it is valuable for research on new plant species and for medical research on animals. Third ly, it suddenly opens everyone’s eyes to the possibility of using cloning to cure serious illnesses, and even producing human beings.T: What is the writer’s opinion? What do you think is the writer’s point of view in this reading passage? Is it in favour of cloning or against it?S1: I think the writer is in favour of it, because there are many advantages of cloning. It can help people solve many problems in our daily life.S2: I think the writer doesn’t agree with it, because if the cloning technology can be used in an evil way, it can cause much trouble to our society.T: The next question: What is your opinion of cloning? Give the reasons.S1: As a coin has two sides, everything has two aspects. First, if the cloning is used in a correct way it can bring many conveniences to us. Such as: curing serious illnesses and being used to produce commercial qualities of plants. On the other hand, if the cloning is used in an evil way it can cause much troubles: such as moral questions.S2: My view on cloning and nuclear transfer is that it is ethical. So actually I find no reason to clone presently. I have this opinion currently, because scientists are unable to successfully clone using nuclear transfer as of today.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 Clone? 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?The Second Period ListeningStep I Revision1. Greetings2. RevisionStep Ⅱ Pre-listeningWork in groups to discuss how we should behave towards the human clones.T: Before human clones become part of our life, perhaps we should spend some time thinking about how we should behave towards them. Now, work in groups to discuss the followingquestions.Show the following.1. How would you treat human clones?2. Do you think they should have legal and political rights, such as getting married or voting?3. Do you think they are separate people or part of the original donor?Sample answers:1. I will treat them as normal people.2. Yes, I think they should have the legal and political rights.3. I think they are separate people.Step Ⅲ ListeningThe students are asked to read fast the questions and multiple answers to find out the listening points first, and then listen to the tape twice to choose the best answer.Step Ⅳ Listening task (P57)First, ask the students to read these sentences and then listen to the tape and decide if they are facts or opinions. Play the recording and then check the answers with the class.Sample answers:Arguments for cloning pets:1. Favorite pets can live forever as clones.2. It is moral to clone pets for their owners.Arguments against cloning pets:1. Many people don’t agree with cloning.2. Some people think that cloning pets is selfish.Step Ⅴ HomeworkT: Boys and girls, today we have listened to some materials about cloning. I do hope you can listen to the materials again after class so that you can get very familiar with them. Besides, please preview the reading. Now class is over. Goodbye, everyone.The Third Period SpeakingStep Ⅰ Lead-inStep Ⅱ Read and answer (P16)To answer these three questions, teacher can give the students some examples as explanation, for example, Question 1.T: Now think about this question: if in the world there is only one sheep and human beings want to clone more. Some days later a Dolly appears, then many more. But one day all sheep get the same deadly disease. Now please think about what the results are.S: Maybe they would all die.T: Why?S: Because all sheep have the same arrangement of genes.T: Right. Now can you answer Question 1? Why shouldn’t you clone an extinct animal unless there is enough diversity in the group?S: It is useless to clone an animal if there is not enough diversity in the group for it to overcome illnesses.T: Why is it wrong to clone an extinct animal if it would have to live in a zoo?S: If the cloned animals have to live in the zoo, it is unfair to them. They need freedom.T. Why can’t you clone the DNA of animals that have be en extinct longer than 10,000 years?S: Dinosaurs disappeared 65,000,000 yeas ago. So the chance of dinosaurs returning to the earth is merely a dream.Step Ⅲ Discussion (Question 2)This is a speaking task.

What problems did you have growing up and how can you help him / her avoid them.Step Ⅵ HomeworkT: Write down your feelings and attitudes towards clone. Combine them into a composition.The Fourth Period GrammarStep Ⅰ RevisionCheck the students’ homework.Step ⅡGrammarT: 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 connected with the verb either directly or by means of the representative it.This cannot hide the fact that he is growing old.We must face the fact that we are living in a revolutionary world.Some supplements:同位语从句与that引导的定语从句1) 从先行词看同位语从句与名次之间在逻辑上是“主语+be+表语”的关系。
