111 Unit 20 Futurology 一、教學(xué)課型：閱讀課 這是本單元第一篇閱讀文章，它給學(xué)生提供了一個近距離感受科學(xué)技術(shù)迅猛發(fā)展的機會，讓學(xué)生了解到什么是未來學(xué)和未來學(xué)家，從而鼓勵學(xué)生積極、勇敢地面對人類社會所面臨的經(jīng)濟、政治、文化等多方面的挑戰(zhàn)。 二、教材分析 1、教學(xué)內(nèi)容 (1) Before reading 21st century Mobile Phones Generations Features 1G Receive\make calls within the mobile phone network 2G Send SMS cheaply 3G Send photographs and video images\Access the Internet What of the future? It has been predicted that mobile phones might soon replace our wallets. For example, instead of handing over cash to pay for groceries, our mobile phones would be scanned and the cost added to our next phone bill. The idea that in the future we won’t need to carry money seems crazy, but 80 years ago, the idea that you could walk out of your house with your phone in your hand probably seemed crazier! Mobile phones have become a major part of our lives and one wonders what the next technological advance will be. (2) Reading Hannah Jones looks into the future of futurology. I love talking about the future --- and I am not the only one. Over the centuries, people have always wondered about the future. Some like to read fantasy stories and imagine what the world will be like in 10, 50 or even 1’000 years’ time. Others foresee future opportunities and problems. They plan the future of the world for a living. These people are called futurologists. This weekend, hundreds of futurologists are meeting at Newcastle University. The seminar starts on Friday and the experts will be discussing the influence of technology on the future. The future is now big business. I clicked into the websites of some futurologists and here’s what they’re predicting: ·The technology already exists, so very soon all of us are going to use our voices to give instructions to computers. ·In the next few years, we will be communicating with our friends around the world using life-sized video screens in our living rooms. ·By the year 2020, computers will already have become more handy and also more powerful than the human brain both in terms of intelligence and the amount of information they can store. ·By the year 2030, development in biochemistry and medical science will make it theoretically possible for us to live for at least 150 years. Tiny, insect-like robots may be sent around our bodies to carry out repairs and keep us healthy. ·By the middle of the century, computers that are millions of times smarter than us will have been developed. We will be linking our brains to these computers and a huge database. A new species might have developed! ·By the end of the century, we will have discovered other places in our solar system suitable for living and will have discovered ways to go further into space. I’ll be there in Newcastle this weekend. At nine o’clock on Saturday morning, I’ll be sitting in the front row and listening to the great Duke Willard talking about the future of my brain. If you can’t beat the future, join it!

At a depth of 200m below the sea, there is still about 1.5% dissolved air. Fish gills work comfortably with this amount of air, and now Israeli inventor Alon Bodner has designed a way for man to do the same, eliminating the need for cumbersome oxygen tanks and expensive air compression units. If it goes to plan, a tankless underwater breathing system in the form of a vest that will be attached to a diver should be available in a few years time.

To practise using the words and expressions. To practise using the Future Perfect and Future Continuous tense. 4、教學(xué)重點和疑點 (1)To help students summarize the main idea of each paragraph and decide an appropriate headline for the text. (2)To practise using the Future Tenses to give future predictions. 三、教學(xué)設(shè)計 1、總體思路 本課的教學(xué)設(shè)計以學(xué)生先學(xué)為主，輔之以教師的精講精評。因而教學(xué)整體過程以學(xué)案形式呈現(xiàn)。學(xué)生獨立通過課前或課中自學(xué)，初步了解相關(guān)內(nèi)容，發(fā)現(xiàn)問題，與同伴討論、交流，教師引領(lǐng)其研究、分析、解決問題。因而學(xué)案中必須明確學(xué)習(xí)目標(biāo)、具體閱讀方法、學(xué)習(xí)重點和疑點、課前預(yù)習(xí)先學(xué)、課堂交流研討、課內(nèi)訓(xùn)練鞏固、課后拓展延伸等內(nèi)容。 2、教學(xué)過程 Step1 Before reading 1. Watch an advertisement on mobile phones. [設(shè)計說明]觀看手機廣告，以圖片直觀形式集中學(xué)生注意力，使學(xué)生自然進(jìn)入學(xué)習(xí)狀態(tài)。 2. Talk about what 4G mobile phones will be like. [設(shè)計說明]通過小組（4-6人）討論，讓學(xué)生描述未來手機的外觀及性能，為下面的閱讀理解及語言運用打下埋伏。 3. Discuss what Futurology is concerned about. [設(shè)計說明]學(xué)生對“未來學(xué)”比較陌生。通過多媒體輸入相關(guān)背景信息，有利調(diào)動學(xué)生的情緒，排除陌生感，喚起其親近科學(xué)技術(shù)的沖動，還可幫助學(xué)生更好地理解本課閱讀文章。 Step2 Reading 1. Read the text quickly. Summarize the main idea of each paragraph. Paragraphs Main idea Vocabulary P1 P2 P3 P4 [設(shè)計說明]通過快速閱讀，學(xué)生可快速獲取文章每一段的主要信息，即訓(xùn)練學(xué)生有目的進(jìn)行閱讀，又為歸納全文主旨大意做好準(zhǔn)備。 2. Decide which of the following headlines will be the best title of the text and give reasons. From the Past to the Future The Future Business Tomorrow’s World A perfect Future? _____________________________________________________________________________________________________________________________________________________________. [設(shè)計說明]這一步驟可促進(jìn)學(xué)生對已獲得的信息進(jìn)行分析和篩選，提高學(xué)生語言表示及概括能力。 3. Find out how many predictions the writer has found on the Internet. And complete the table. [設(shè)計說明]確定了文章主旨大意之后，將注意力聚焦具體信息，可自然轉(zhuǎn)入新的語言點（將來完成時和將來進(jìn)行時）的學(xué)習(xí)。 4. Voice your opinions: Why is the writer interested in futurology? Which of the predictions would you like to come true? [設(shè)計說明]學(xué)生有了足夠的語言輸入后，可嘗試組織語言并輸出信息。這樣，即能引領(lǐng)學(xué)生領(lǐng)會作者的寫作意圖，又給空間學(xué)生圍繞主題展開對未來的憧憬。 5. Read the text again and speak out at least one sentence you think excellent. [設(shè)計說明]提供機會學(xué)生說自己喜愛的句子，即突出了學(xué)生課堂的主體地位，又可培養(yǎng)學(xué)生更高的學(xué)習(xí)熱情。與同伴交流，還可檢查發(fā)音及語速，促進(jìn)合作提高。 Step3 Post-reading 1. Tell the statements T or F according to the information in the table. [設(shè)計說明]改編練習(xí)10的形式，可將鍛煉學(xué)生閱讀信息、理解信息的能力與運用新語言知識的能力結(jié)合起來。另外，考慮到不少學(xué)生以前做類似練習(xí)都覺得較難，這樣處理也可降低難度。 2. Read the news from China daily. First underline the topic sentence and then decide a title for it. [設(shè)計說明]從課內(nèi)到課外，將學(xué)校學(xué)習(xí)與社會新聞結(jié)合，引導(dǎo)學(xué)生關(guān)注社會，關(guān)注科學(xué)技術(shù)對人類生存的巨大影響，是課堂教學(xué)不可忽視的一方面。同時，也進(jìn)一步突出了本節(jié)課把握文章主旨大意、培養(yǎng)閱讀能力的目標(biāo)。 Step4 Homework 1. Match the vocabulary with the explanations. 2. Complete the sentences with the correct form of the words given. [設(shè)計說明]學(xué)生認(rèn)為閱讀的最大障礙是詞匯不過關(guān)。這兩個練習(xí)可幫助學(xué)生歸納、理解和運用本課詞匯。 3. Read more information about “the Future” and do exercises. [設(shè)計說明]課堂中，學(xué)生對將來完成時和將來進(jìn)行時已自然地運用上了，但還存在疑慮。學(xué)生通過對具體材料的感悟，可自己歸納、整理和完成任務(wù)。教師只需個別點評。 111
