本模塊以Sandstorms為話題，通過本模塊的幾篇閱讀材料使學(xué)生對

Sandstorms有所了解，并通過文章中提出的一些深刻的問題，比如，Thedesertis

only250kilometersawaytothewestofBeijing使學(xué)生更好地了解我們的地球和我

們的生活環(huán)境正遭受的破壞，并引發(fā)對“我們應(yīng)該如何保護(hù)環(huán)境”的熱烈討論，通

過這些討論會(huì)激發(fā)學(xué)生對環(huán)境保護(hù)的了解和實(shí)施的自覺性。通過討論

Sandstorms,讓學(xué)生表達(dá)對沙塵暴的看法，以及我們應(yīng)采取何種措施來提高環(huán)境

質(zhì)量。并能就此設(shè)計(jì)海報(bào)來呼吁人們保護(hù)環(huán)境。

1.1INTRODUCTION復(fù)習(xí)和學(xué)習(xí)有關(guān)自然災(zāi)害的詞匯，呈現(xiàn)了一些自然災(zāi)

害的起因以及造成的危害，使學(xué)生對沙塵暴有初步了解。

1.2READINGANDVOCABULARY就有關(guān)沙塵暴的圖片提出問題來導(dǎo)入

課文。閱讀文章后并完成練習(xí)，培養(yǎng)對詞匯的應(yīng)變力，理解力和分析問

題的能力。

1.3GRAMMAR1部分不定式的不同表達(dá)的區(qū)別，并會(huì)正確運(yùn)用。

1.4LISTENINGANDVOCABULARY通過聽的活動(dòng)，了解和學(xué)習(xí)與環(huán)境有

關(guān)的詞匯并學(xué)會(huì)表達(dá)，培養(yǎng)在聽的過程中思維能力和獲取信息的能力。

1.5GRAMMAR2了解but+infinitive的用法。

1.6PRONUNCIATIONANDFUNCTION學(xué)會(huì)expressstrongopinions的表達(dá)

法。

1.7SPEAKING1設(shè)置一個(gè)情景來表達(dá)在沙塵暴中的一次經(jīng)歷。

1.8SPEAKING2通過詞匯練習(xí)來了解造成環(huán)境污染的一些東西，并就此提

出解決措施。

1.9WRITING先描述一些環(huán)境問題，然后再就此提出解決的措施，然后組

1.10EVERYDAYENGLISH學(xué)習(xí)一些短語和句子的表達(dá)，并在日常生活

中加以運(yùn)用。

1.11CULTURALCORNER了解一些歐洲國家在環(huán)保方面所采取的措

施。

1.12TASK通過設(shè)計(jì)一個(gè)海報(bào)來鼓勵(lì)人們保護(hù)環(huán)境。
