Unit 4 Astronomy the science of the stars教案（人教版必修3）Period 5Using language: Extensive reading整体设计教材分析This is the fifth teaching period of this unit. As usual, the teacher should check students’ homework and offer chances for them to go over what they learned in the last period at the beginning of the class. Then lead in the new lesson.In this period, the teaching emphasis will be put on developing students’ reading ability by reading extensively. We will deal with two parts: A VISIT TO THE MOON in Using language on Pages 30-31 and CAUGHT BY A BLACK HOLE in Reading Task on Page 66. While reading, get students learning to use some reading strategies such as skimming, scanning, and so on. As to new words and phrases, the teacher can first find those students feel most difficult and help them to understand. That’s enough here. The reading passage A VISIT TO THE MOON is a science fiction story which imagines what it might be like if an astronaut visited the moon. The purpose of science fiction writing is to combine facts with a story to make students interested and excited about travel in space. It is also to stimulate awe and wonder into the vastness of space. As this reading uses the information students have gained from the listening, the teacher can first ask some students to retell the listening text to lead in the topic and then ask students to read the passage and do some comprehending exercises. While checking their answers with the whole class, deal with language problems students can’t work out by t hemselves. This is an extensive reading lesson, so the teaching steps should be simple. As to the passage CAUGHT BY A BLACK HOLE, it is to continue the above story. The astronomers in the story visit a place in space, which seems impossible for people to reach, the “black hole”. It is to help students imagine what it is like near a “black hole”. Ask students to read through the passage and try to know more about astronomy and gravity.At the end of the class, ask students to retell the two passages. In order to arouse students’ interest, the teacher can hold a competition among them.教学重点1. Develop students’ reading skills by extensive reading.2. Let students read and understand the two passages.教学难点1. Enable students to learn to use reading strategies such as skimming, scanning, and so on.2.

Ask some pairs of students to come to the front and act out their dialogue to review the expressions of giving instructions.3. Have some students talk about Isaac Newton, Albert Einstein and Stephen Hawking as well as their ideas on gravity.→Step 2 Warming upLet students to brainstorm the following questions:What country first sent people into space?How many countries have succeeded in sending people into space so far?Who first landed on the moon?Who is the first Chinese astronaut to go into space?Do you want to visit the moon?→Step 3 Reading1. Ask students to read the passage and then describe the three ways in which gravity changed for Li Yanping and how his weight changed.1) Write down the three ways in which gravity changed for Li Yanping.The way gravity changedLeft the earthIn spaceOn the moonSuggested answers:The way gravity changedLeft the earth The gravity became very strong.In space The gravity disappeared.On the moon The gravity became very light.2) His weight changed three times, too. Now write them down.How his weight changedLeft the earthIn spaceOn the moonSuggested answers:How his weight changedLeft the earth He became very heavy.In space He had no weight and could float around like a feather.On the moon He was about one-sixth of his weight on the earth.2. Ask students to read the passage aloud to the tape and underline all the useful expressions or collocations in the passage. Let students read them aloud and copy them down in their exercise book after class as homework. Try to keep them in mind.Collocations: be lucky enough to do, have a chance, make a trip into space, explain sth. to sb. , the force of gravity, be off, the pull of the earth’s gravity, fall back to the earth, fall to theground, too far from the earth, as if, at all, get close to, cheer up, come on, less than, down the steps, step forward, twice as far as, fall over, a bit of, now that, after a while, get the hang of, break out, on the outside of, be pushed into→Step 4 Important language points1. Before we left, Li Yanping explained to me that the force of gravity would change three times on our journey and that the first change would be the most powerful.在启程以前, 李彦平向我解释说, 在我们的航行中会有三次引力的改变, 而第一次的改变将是最强的。

One expert points out that the percentage(比率) of native English speakers is declining(降低) globally while the languages of other rapidly growing regions are being spoken by increasing numbers of people. But English will continue to remain widespread and important.However, British language scholar David Graddol says English will probably drop in dominance(主导) by the middle of this century to rank, after Chinese, about equally with Arabic, Hindi, and Urdu. “The number of people speaking English as a first language continues to rise, but it isn't rising nearly as fast as the numbers of many other languages around the world, simply because the main population group has been largely in the less developed countries where languages other than English have been spoken,” he says.In a recent article in the journal Science, Mr. Graddol noted that three languages that are not near the top of the list of the most widely spoken now might be there soon. These are Bengali, Tamil, and Malay, spoken in south and Southeast Asia.David Crystal, the author of the Cambridge Encyclopedia of the English Language, says about 1.5 billion of the world's six billion people speak it as a second tongue compared to the 400 million native speakers. But another expert on the English language says Mr. Graddol underestimates (低估) the future of its dominance. “Nobody quite knows what's going to happen because no language has been in this position before. But all the evidence (证据) suggests that the English language snowball is rolling down a hill and is getting faster,” he said.36. In David Graddol's opinion, English will _______.A. remain widespread and importantB. be more important than any other languageC. lose its dominant positionD. die away in the near future37. The underlined sentence in the last paragraph implies that ______.A. snowballs will roll down faster than language ballsB. the English language snowball is rolling down faster than any time in the pastC. English language will soon drop in dominanceD. more and more language users will choose English38. How many experts does the passage mention who express their ideas about the future of English?A. 2.B. 3.C.4. D.5.39. According to David Graddol, which of the following will possibly be one of the languages that will be most widely spoken?A. Malay.B. Arabic.C. Urdu.D. German.40. What should be the best title for the passage?A. English Remaining the Dominant PositionB. The Future of English? Who Knows?C. Opinions from Different ExpertsD. The English Language Snowball Rolling DownBLanguage learning begins with listening. Children are greatly different in the amount of listening they do before they start speaking, and later starters are often long listeners .Most children will “obey” spoken instructions some time before they can speak, though the word “obey” is hardly accurate as a description of the eager and delighted cooperation usually shown by the child .Before they can speak, many children will also ask questions by gesture and by making questioning noises. Any attempt to study the development from the noises babies make to their first spoken words leads to considerable difficulties. It is agreed that they enjoy making noises, and that during the first few months one or two noises sort themselves as particularly expressive as delight, pain, friendliness, and so on. But since these can't be said to show the baby's intention to communicate, they can hardly be regarded as early forms of language. It is agreed, too, that from about three months they play with sounds for enjoyment, and that by six months they are able to add new words to their store. This self-imitation（模仿）leads on to deliberate（有意的）imitation of sounds made or words spoken to them by other people. The problem then arises as to the point at which one can say that these imitations can be considered as speech.It is a problem we need to get out teeth into. The meaning of a word depends on what a particular person means by it in a particular situation and it is clear that what a child means by a word will change as he gains more experience of the world .Thus the use at seven months of “mama” as a greeting for his mother cannot be dismissed as a meaningless sound simply because he also uses it at other times for his father, his dog, or anything else he likes. Playful and meaningless imitation of what other people say continues after the child has begun to speak for himself, I doubt, however whether anything is gained when parents take advantage of this ability in an attempt to teach new sounds.41. Before children start speaking________.A. they need equal amount of listeningB. they need different amounts of listeningC. they are all eager to cooperate with the adults by obeying spoken instructionsD. they can't understand and obey the adult's oral instructions42. Children who start speaking late ________.A. may have problems with their listeningB. probably do not hear enough language spoken around themC. usually pay close attention to what they hearD. often take a long time in learning to listen properly43. A baby's first noises are ________.A. an expression of his moods and feelingsB. an early form of languageC. a sign that he means to tell you somethingD. an imitation of the speech of adults44. The problem of deciding at what point a baby's imitations can be considered as speech________.A. is important because words have different meanings for different peopleB .is not especially important because the changeover takes place graduallyC. is one that should be properly understood because the meaning of words changes with ageD. is one that should be completely ignored（忽略）because children's use of words is often meaningless45. The speaker implies________.A. parents can never hope to teach their children new soundsB. children no longer imitate people after they begin to speakC. children who are good at imitating learn new words more quicklyD. even after they have learnt to speak, children still enjoy imitating卷 II一. 单词拼写1.
