牛津译林版高中英语必修二《Unit 1 Tales of the unexplained》Reading 教学设计1
牛津译林版高中英语必修二Unit 1 Tales of the unexplained Reading 教学设计1单元：Unit1 Tales of the unexplained板块：Reading1设计思路：本节课为阅读课的第一课时，主要是解决对课文内容的理解和学习有关阅读技巧。
本文的体裁是新闻报道，采用新闻报告的常规要点为切入口，从title和五个“W”一个“H”这几个方面构画出新闻报道清晰的框架结构并教学生如何阅读此类文章，如何在此类文章中捕捉所需要的信息。
教学方法还是通过预测、略读和寻读等常规技巧，帮助学生了解课文内容。
教学步骤的设计以培养说、读、写能力为主。
(PPT3)Teaching aims:After learning the passage, students will be able to know typical writing features in news articles and learn how to read a newspaper article and how to get the important information in it, thus reinforcing their reading abilities in reading this kind of material. Besides, students should be encouraged to express themselves in both written and oral English so that their language learning abilities can be enhanced.Teaching procedures:Step 1 Lead-in● Warm-up questions:1. Do you often read newspapers? (often, seldom…)2. How do you select the news you like to read, by taking a look at its title or by being attracted by its colorful pictures?1.3. Have you ever noticed there are differences in writing styles between newspaper articles and other kind of articles you read?4. Can you tell me the feature of a news title? Let's take the passage we’re going to learn asan example, the title is “Boy missing, police puzzled”, what’s special? (The title of a news story is usually incomplete, attractive, exact and direct …)5. Can you complete the title? (“A boy is missing, and the police are puzzled”)6. What information can you get from the title? (How/when/where was the boy missing?;why are the police puzzled?). Tell the students a news story will cover such details as what, when, where, who, how and why about a certain event.—PPT5[设计说明]通过问题的提出让学生对要学的文体特点先有个粗略的了解，同时希望能激发学生对马上要学的内容的兴趣。
● Pair work: —PPT6Now look at the pictures from our reading te xt and connect them with the topic “Boy missing, police puzzled”. Use your imagination and guess what happened in the story according to the information we get from the topic and the pictures. —PPT Work with your partner and then share your story with the rest of the class.[设计说明]鼓励学生发挥想象力，激发学生对要学内容的兴趣。
● Summary:I'm sure you definitely want to know what really happened in the news story to check your imagination, but before reading the story, I should tell you how a news story is organized so that you may catch the important information in it more easily.Step 2 Reading strategy: (PPT7-9)Learn the structure of a news story and teach the reading skills of news stories.1. The structure of a news story● the title: to give a general idea of the news● th e first paragraph: to give the main topic and the most important facts like when, where, who, what, why and how about the event;● the second paragraph: to give more important facts● the following paragraphs: to give detailed but less important background information2. The reading skills of news stories● For general ideas, read the topic if any and the first one or two paragraphs; for details，read the rest of the story.[设计说明]在学习课文内容之前先教阅读策略与技巧，然后鼓励学生运用刚才学习的技巧去阅读，方便教师了解学生对该技巧的掌握情况，也有利于培养学生的阅读技巧和促进学生阅读理解能力的提高。
Step 3 Skimming& Scanning1. Tell the students it’s time for them to check their imagination of the story. Ask the whole class to skim and scan the passage, trying to find the answers to the following. (PPT10)● Boy missing, police puzzled it’s a bout ________● the first paragraph: when______; where_______; who________; what________; how______; why________● the following paragraphs: evidence given by______________2. Ask how many of the students guessed the story right at the beginning of the class. Tell the students to attach importance to news titles if any while reading news stories.[设计说明]希望以此练习来帮助巩固前面所学的阅读技巧之一，即让学生明白如何捕捉新闻类文章的大意，那就是抓住文章开头，尤其是第一节。
另外，要向学生强调新闻类文章标题的特点。
Step 4 Detailed reading1. Since every news story will have details to support the main points in them. Get the students to read the passage carefully and find the supporting details. (PPT11)● Read paragraph 2 and find the main idea as well as the supporting details:Main idea:Supporting details: Mrs. Foster thoughtMr. Foster was surprisedJustin Foster(Justin Foster went missing; he was spending the night with a friend; that his son did not tell anyone that he was staying out late; did not show up at the family lunch the next day.)● Read paragraphs 3&4 and find the main idea as well as the supporting details :( PPT12)Main idea:Supporting details: Justin’s friends saidWitnesses saidKelly heard( The police found that Justin returned home; that Justin went home after playing baseball with them; that they saw Justin walking towards his home at 10:45 p.m; him put on his favorite CD after he went to his room.)● Read paragraphs 5&7 and fi nd the main idea as well as the supporting details :( PPT13)Main idea:Supporting details: Kelly sawKelly heardMavis Wood said(The boy was taken away by aliens; a large spaceship flying outside; Justin shout; that the aliens took her away so that they could do scientific research on her.)2. Find the best answers to the following questions :( PPT14-18)(1)The reason why people were interested in the disappearance of the boy is that __C___.A. The lost boy was 15 years old.B. The police advised them to do so.C. The disappearance might have something to do with the UFO and the alien.D. All of the above.(2)In the second paragraph, “show up” means _____A____.A．Arrive or appearB．ReachC．DisappearD．Reach for(3)We can infer that the boy might go missing ___A______.A．In his own roomB．On the playgroundC．In Kelly’s roomD．In his brother’s room(4)What is the attitude of the police to the disappearance of the boy? ___D____A．They can’t make sure that Justin was taken away by aliens.B．They think it possible for some people to make up an amazing story.C．They are looking at other possibilities, such as murder.D．All of the above.(5)We can know ___B____.A．The police have known the cause of the boy’s disappearanceB．The police haven’t found convincing evidence about the boy’s dis appearanceC．The police will catch the aliens who took away the boyD．The police won’t get any information about the boy’s disappearance.[设计说明]希望通过此环节让学生了解一下与此故事相关的一些细节，并学会如何根据细节来进行归纳、推断，培养学生的阅读理解能力。

Unit 1 Tales of the unexplainedPart 1: Teaching DesignAims and requirementsRead a news story about a missing boy and a magazine article about Yeti Listen to a dialogue between a boss and his employeeTalk about aliens and conduct an interviewWrite a reportTell a mysterious storyProceduresPeriod one, Welcome to the UnitStep 1: Brainstorming1. Boys and girls, have you ever heard something not only interesting andattractive but also unexplained at all even with the help of modern science and technology in the world? Here are some pictures on the screen. Can you tell me what they are?The chances for seeing a UFO are greater for those people who live in small towns or in the country and are outside late at night.UFOs. Yes, they are called UFOs, meaning unidentified flying objects.UFOs come in all shapes and sizes. Some are only small spots of light that move in strange patterns across the night sky.Some can be seen in the daytime are often disk- or saucer-shaped.UFOs were once seen in different parts of China. Look at some pictures on the screen, please.Do you think such kind of things mysterious ? Are you curious about them? Besides UFOs, can you list anything more unexplained you’ve ever heard or seen in your daily life?They are Yetis, the Loch Ness Monster, Stonehenge and the Pyramids in Egypt.2. Open your books and let’s look at page one. Please read the instruction and focus on the five pictures and illustrations first. Then answer the following questions:Do the five pictures have something in common?If so, what is it? (unexplained; no satisfactory answers; mysterious; no evidence...)Can scientists explain these phenomena?How do you feel about them?Are you a bit curious?3. Think of as many expressions as possible to answer the questions above. Try to make up some sentences and read them to the class. I will also offer you some examples.They are mysterious because no satisfactory answers have been offered to explain them. Though these mysteries have puzzled people for a long time, they still show great interest in them.People feel puzzled by the mysteries.4. Report the information you have collected to the class. Your answers are quite different. Now we will use some of your answers as a prompt for a class discussion. For example,Teacher: What information have you got about UFOs?Student A:...Teacher: Do you think Student A's information interesting? What about the information you've got? Is there anything different?Student B:...5. Please discuss the topics in pairs. Here are some questions.About UFOs:Have you ever read some reports about UFOs in China?Are you interested in UFOs?Are they really from another planet?What do the letters UFO stand for?Why do you think UFOs visit our planet?About Yetis:Where are the Himalayas?What's the weather like there?Why do some people make great efforts to climb them?(hobby; dream; challenge themselves; make discoveries; overcome difficulty,..)A Yeti is reported to be half-man and half-beast. Have you heard of it?Do you think some climbers' disappearances are connected with Yetis?About Stonehenge, the pyramids and the Loch Ness Monster:Stonehenge and the pyramids in Egypt, the most famous of which is the Great Pyramid, are cultural relics.Where were the pyramids built, on the east coast of the Nile or on the west coast?What are the reasons?Do you think the Great Pyramid is a wonder in human history?How was the Great Pyramid built?I haven't heard of Stonehenge or the Loch Ness Monster. They are a bit new to me. What about you?Would you be interested in discovering more about them?Step 2: Sharing information1. Let’s deal with the questions in pairs. For the first question, you may discuss it this way: Do you believe in UFOs? What might be the most acceptable explanation for UFOs? You may give different answers such as:-Aliens from space.-Military test aircraft.-Some UFOs are alien, some are test aircraft.-UFOs are evidence of human space travel.-UFOs are neither alien nor test aircraft.-UFOs don't exist.You can express your agreements and disagreements with each other.2. Summarize your answers and then report to the class.Sample answers1. I have a firm belief in UFOs. In fact, I have seen a few myself. UFO stands for Unidentified Flying Object, that is, an object, apparently moving in the sky, which we cannot identify. However, if you ask me whether or not I believe in spacecraft carrying visitors from outer space, I would have to say 'no'.I do not believe in them.2. The continent of Antarctica was discovered in 1818. It was once supposed to have been covered by ice for hundreds of thousands of years. However, in 1949 scientists took samples from sediment deep beneath Antarctica, which revealed that great rivers had once flowed into Antarctica until about 6,000 years ago, Many more mysteries remain to be discovered.3. I'm always interested in the stories of UFOs and aliens. And I hope I will have the chance to meet one some day. If it really happens to me, I will ask questions such as 'Who or what are you?', 'Where are you from?' and 'How long does it take to travel from your place to our planet?'. I will try my best toPeriod two, Reading boy missing ,police puzzledStep 1: Lead-in1. Some questions about UFODo you know what the three letters UFO stand for?Have you ever heard of the UFOs?Have you ever had the chance to see one?Do you believe the usual sayings about the UFOs?What do you think a UFO is?Do you think there are any creatures on it?Where do you think the creatures come from?Will they become our friends or enemies?2. Today, we’ll come to Reading part. Now I’d like you to look at the pictures on pages 2 and 3 and the title, Boy missing, police puzzled. Can you connect them with each other?Picture 1:Is the first picture a UFO?Are there really UFOs from the outer space?Picture 2:Who was the missing boy?Does he like playing football or baseball?Picture 3:What’s the picture about?Does the bright light outside the window come from a UFO?Does the bright light have something to do with Justin’s missing?(If possible, the teacher may use the projector or macromedia to show the situations in the three pictures and ask the students the same questions as given above. Check answers in pairs. Check the answers with the whole class if you wish.)3. Answer the following questions, focusing on the title of the article, Boy missing, police puzzled.Does the title arouse your interest when you read it?Can you complete the title?What information can you get from the title?What else do you want to know? For example, 'boy missing' (How/When/Where was the boy missing?) 'police puzzled' (Why are they puzzled?/What are the police going to do about the boy's disappearance and how?)Are you curious about why the writer uses an incomplete sentence as the title? Did you know that it is a feature of a news title?What are some other features of a news title?Can you guess what details may be covered in the following news story? Step 2:Fast reading for general ideas1. Before skimming the passage, please look at the news photographs first and describe what is happening in them. Then find the answers to the three questions above the text:1) What is the article about? (The article is about a missing boy/UFOs and aliens.)2) Who is missing? (Justin Foster is missing.)3) Do the police know what happened to Justin? (No.)2. Read the first paragraph carefully to get the main idea and the important facts such as: When and where was the boy missing? What caused the boy's sudden disappearance? How old was the boy? Why did people show interest in his disappearance?3. Now scan the article again and locate specific information according to Parts C1 and C2. Questions 1, 2, 3 and 5 in Part C1 check background information about Justin while Questions 4, 6, 7 and 8 check your comprehension about witnesses,aliens and the case. Part C2 requires you to identify some details to support the main points of the story.Step 3: Detailed reading for important information1. Please self-evaluate how well you understand and comprehend the article with the following exercise.At 8 p.m.___________________________________At 10.45 p.m._____________________________Justin Foster At 11 p.m.___________________________________After 11p.m., he was seen_____________________The next morning, he was found________________shape__________________its appearance colour__________________Strange objects (UFO) size______________________its inside ___________________________________2. Answer the questionsWhere does Justin Foster live ? （He lives in Dover, New Hampshire.）Why did Justin’s mother go to bed early? (Justin’s mother went to bed early because of a headache.)What sports does Justin play? (He plays basketball.)What time did the witness see Justin walking home? (At 10.45 p.m.)Does Justin have any brothers and sisters ? (He has a sister)What colour were the aliens? (They were white.)Who else has been taken by the aliens? (Mavis Wood has been taken by the aliens.) Who is in charge of the case ? (Detective Sam Peterson was in charge of the case.)3. Complete Parts D and E. The meanings of the words in Part D are not difficult for you to identify after you have read through the passage twice. Part E is a diary written by Kelly. It requires you to understand the diary first, and then write down the missing words to make the meaning complete.3. Having read the text, please pay attention to the different features of each paragraph.1) First let’s have a discussion about how we usually decide whether a news article is worth reading or not and what methods we use in our reading.As we all know, newspapers play an important part in our daily life. Wherever you are, you can be informed of the latest news by reading a newspaper. From your experience, how do you usually select the news you’d like to read, by taking a look at its title or being attracted by its colorful pictures?Every one of you can express your own opinions and give the reasons. 2) Compared with the other paragraphs, is the first paragraph the most important one in the article? Please describe the differences between the first paragraph of the article and the paragraphs that follow.3) You are asked to read the Reading strategy ‘reading a newspaper article’. Pay attention that both the title and the first paragraph, which is called the lead paragraph, play a key role in your understanding of news articles. Step 4: Post-reading activities1. Retell the story according to the diagram on page 6. I’ll write down some key words and phrases on the blackboard or the overhead projector for you to refer to in case you need help.2. Suppose you are a writer. Please give an ending to the story. Though the police have made efforts to investigate the case. Justin's disappearance remains a mystery. Was he really seized by aliens or were there other reasons? All the people are concerned about Justin's disappearance. What do you think might have happened to him? Was he in danger? If he were taken away by aliens, how do you think they would treat him? Just use your imagination and all the endings are acceptable.3. Do with Parts A1 and A2 on page 80 in Workbook to get more familiar with the text and the words and expressions in it.4. Please turn your attention to the questions in Part F. You are expected dosome speaking practice according to the sample.5. Read Part A first and then do Part B in Writing on page 87 in Workbook.Listen to me, please. Space exploration began with the launch of the first artificial satellite. What does 'launch' mean? What word can be used to replace 'artificial'? What about the word 'man-made'?3. Now continue with your discussion by answering the following questions: How can a space shuttle be sent into space?Can it fly into space by itself?With these two questions, you should focus on reading the poster the scientist is showing to you. By the way, do you know the differences between spaceship and space shuttle?▲A spaceship is a vehicle for carrying people through space.▲A space shuttle is a vehicle that is designed to carry people into space and back to the Earth several times to do experiments.Think about other information the scientist may refer to in the following part of his speech.4. Read the second part of the scientist's speech and complete Part C individually according to the instructions. We’ll then check the answers. Answers to C (Page 7)I guess some of you are dreaming an astronautTo check your reading comprehension, I’d like to ask you some questions: What will happen to the rockets after the shuttle has been sent to space? Where will the astronauts do their research?Why can't they remove their spacesuits?Step 3: Vocabulary extension1. Right now we've got some knowledge about space and space exploration, and learned some relevant words and expressions. Let's review them.inner spacespacePeriod four, Grammar and UsagePresent perfect tense1. Use different methods to present the present perfect tense. Here are some ideas:1) Please look at the screen. Pay attention to the different forms of the verbs:2) Let’s complete the following sentences, in which the predicate part is missing.We_____(study) English for about five years.They_____(live) in the south since their daughter was born.I_______ (read) your article three times. It's well written.The student________(finish) her homework already.Eric__________(go) back to his hometown today.Answers: have studied have lived have read has finished has gone3) Read the following sentences and point out what tense or tenses are used in them and the reasons why they are used.We have studied English for about five years. We began to study it five years ago.They moved to the south in 1990 and have lived there since then.The student is doing her homework. She hasn't finished it yet.Eric left home last year and has just come back.2. We may wonder why some verbs can't be used in the present perfect tense. Let’s read the following sentences, and try to find different usages of some verbs.Justin has been away from home for several days. He disappeared last Friday.They bought this house three years ago and they have lived here since then.My brother went to see my grandpa last week. He has visited him three times this month.So you see when an action happens over a period of time that began in the past and continues to the present, the present perfect tense is often used. When an action happened at a definite time in the past, the past simple tenseis often used.3. Read Points 1 and 2 on page 8 to make sure why the present perfect tense is used in these two sentences.4. Go over Point 3 on page 8 to learn what time expressions can be used with the present perfect tense. Pay attention to the different usages between already and yet, or for and since.5.

And since then let’s see…-…She’s already made the beds, written a letter, gone shopping, and cooked dinner.-And now she’s just answered the telephone for the fifth time.English has a verb tense, the present perfect, which serves to denotepast happenings that are relevant to, or that still have an effect at,the moment of speaking. This tense, formed with the present of have plusa past participle (answered, cooked, gone, written, made, and so on),is really a combination of present and past together. Notice the kindsof adverbs and adverbial phrases that are closely associated with the present perfect.He’s been a success now, I would say, since 1990.And now he’s just decided to enter politics.The simple past, denoting past happenings that are localized in the past, contrasts sharply with the present perfect, as can be seen best by thekinds of “time” adverbials that may be used with one tense but not withthe other.Simple Past PresentPerfectyesterday since thenan hour ago so farI learned a new song last night I’ve learned another nowon Monday in thelast houralreadynow nowthen × then then ×then(past) (future) (past) (future)(Attention is drawn to the past (Attention is drawn tothe present knowledgeEvent and the time it took place.) of the song and not on theprevious act of learning it.)Therefore, do not say things like “I’ve learned a new song yesterday”, which is a very common mistake.The speaker chooses among these and other tenses in part accordingto how he feels himself related to the event.Present perfect continuous tenseHere we will look at two situations in which the present perfect continuous tense is used. Note how the tense is formed and try to understand how the tense is used in sentences. We will practise forming verbs in this tense and complete sentences.1. We sometimes use the present perfect continuous tense to talk about actions that started in the past and are still continuing, or have just finished but are still connected to the present in some way. For example,I've been waiting for an hour and he still hasn't turned up.I'm so sorry I'm late. Have you been waiting long?2. Go over Points 1 and 2 on page 9 to understand this tense better.3. Go over Point 3 to see how the tense is formed.4. Fill in the missing words. Pay attention to the verb form in the example given in the first picture (all the verb forms here are the present perfect continuous tense, except for the one in Sentence 5). It is a trap and does not require the present perfect continuous tense.Answers:(2) have been talking (3) have been taking (4) have been watching (5) have seen (6) have been writing5. Do with Part C1 on page 82 in Workbook to become familiar with the present perfect tense and the present perfect continuous tense.Present perfect or present perfect continuous?1. Go over Point I on page 10 to identify why the two different tenses are used in the two sentences.In the first sentence, the present perfect tense is used, which means that the action read isn't continuing, and Li Jia knows what the book is about now. In the second sentence, the present perfect continuous tense is used, which means that the action read is still continuing.2. Go over Point 2 on page 10. Note that the present perfect continuous tense can't be used with time expressions such as twice or how many times, because in this tense the action is continuous, not stopped and then started again.3. Go over Point 3 on page 10 to define the meaning of a state verb or an action verb. Note that a state verb doesn't mean an action, so it can't be used ina continuous tense.4. Note that the present perfect continuous tense can't be used when the words always, never, yet, already or ever are used in a sentence.5. Finish the two exercises on page 11.Answers:A (1) heard (2)been doing (3) been researching (4) been doing (5) started (6) done (7) read (8) found (9) started (10) been doing (11) been makingSample answers:B 1.

Do with Part C2 on page 82 in Workbook to have one more chance to practise the usage of the two different tenses.ResourceThe Present Perfect Continuous-I still haven’t figured out how she does it all.-I haven’t either, and I’ve been trying now for ten years.The present perfect tense, like the simple present and the simple past,has a continuous form as well. The effect of the present perfect continuous is to make past happenings continuous throughout a time span extending up to the present:Simple Past: I learned a new song (three hours ago).nowHours then ×then(past) (future)(past event accomplished,specific time)Present Perfect: I’ve learned another now (inthe past few hours).nowHours then ×then(past) (future)(past event accomplished, present relevance)Present Perfect Continuous: I’ve been learning still another now (for the past hour).nowHours then ×then(past) (future)(past event not necessarily accomplished, present relevance, possibly still going on at the moment of speaking)Verbs denoting action that can only be momentary or instantaneous (knock, hit, sneeze, interrupt, introducing, and so on) can also occur in the continuous. The meaning, however, is then one of repetition:You’ve been interrupting me now ( for the past five minutes).nowthen × then(past) (future)Although this class of verbs also includes arrive, leave, come, go, and so on, the “repetition” with the verbs just mentioned cannot be effected by one person alone: The guests haven been arriving now for an hour. But not “The guest has been arriving now for an hour.ConsolidationI. Relative items in recent years’ college entrance examinations:1.
