Unit4Earthquake教案

1、Unit4 Earthquake1. 教材分析本單元以地震為中心話題 ，介紹了地震這一自然現(xiàn)象，使大家對(duì)地震的起 因、前兆、危害及如何在震中自救等有了較全面的了解。各項(xiàng)語言活動(dòng)主要圍繞這個(gè)中心內(nèi)容對(duì)人，事，物進(jìn)行了描述。這些練習(xí)內(nèi)容讓學(xué)生思考如何去避免地 震或至少是避免太多的損失。即對(duì)于災(zāi)難要有正確的認(rèn)識(shí)，要用積極的態(tài)度來對(duì) 待它。1.1 Warmi ng-up用唐山和舊金山的兩幅圖片導(dǎo)入本單元，旨在讓學(xué)生運(yùn)用有關(guān)知識(shí)去描述所見圖片，并發(fā)揮想象力來描述震后這兩個(gè)城市的情景。帶著疑問去學(xué)新知識(shí)，來完善自己對(duì)地震的認(rèn)識(shí)。另一方面，它也為學(xué)生提供了功能項(xiàng) 目、短語詞匯、和語法知識(shí)方面的練習(xí)。1.2

2、Pre-reading是Warming-up的延續(xù)。它由對(duì)圖片的想象轉(zhuǎn)入到經(jīng)歷地震的 想象中。由兩個(gè)問題組成。第一個(gè)問題其目的是提高學(xué)生在危急關(guān)頭的應(yīng)變能力， 第二個(gè)問題旨在培養(yǎng)學(xué)生對(duì)周圍事物的觀察能力，并結(jié)合圖片培養(yǎng)學(xué)生運(yùn)用語言 的能力，也對(duì)課文內(nèi)容作了伏筆。1.3 Reading從內(nèi)容來看，它包含了地震的方方面面；從功能項(xiàng)目來看，它 包含了本單元大部分的詞匯和語法內(nèi)容，為下一步的語言運(yùn)用做好了準(zhǔn)備。這是 一篇新聞報(bào)道，記述了唐山地震的前兆，經(jīng)過，危害及救援工作。整篇文章語言 生動(dòng)，扣人心弦，能讓人感到地震的可怕性，也能感到政府對(duì)災(zāi)區(qū)人民的關(guān)懷。體現(xiàn)出了人類在自然災(zāi)害面前的脆弱和戰(zhàn)勝困難時(shí)體

3、現(xiàn)出來的集體主義精神。同時(shí)也讓學(xué)生對(duì)災(zāi)難臨頭時(shí)如何自救等知識(shí)有所了解。1.4 Comprehe ndi ng 是對(duì)目標(biāo)語言的全面練習(xí)，也指導(dǎo)了學(xué)生的學(xué)習(xí)方法 和步驟。它要求學(xué)生從字、詞、句、語段總體上去把握課文內(nèi)容。The First PeriodReading ( I )Teach ing goals 教學(xué)目標(biāo)1.
