教材分析
本單元的中心話題為“拯救地球”，通過課堂導入引出水污染、空氣污染、環(huán)境破壞，亂砍亂伐樹木等環(huán)境問題，圍繞這一主題，結(jié)合聽、說、讀、寫的訓練達到熟悉話題表述，語言熟練應(yīng)用，能運用所學知識就環(huán)境問題展開討論，在口頭上和筆頭上闡述自己的觀點，達到語言輸出的目的。
“熱身”（Warming up）部分，運用圖片導入法，通過對所展示圖片的討論，引出環(huán)境保護、拯救地球的主題，初步了解學生對現(xiàn)狀、原因、解決辦法的掌握程度，并通過提問了解學生對本單元學習內(nèi)容、學習策略、學習途徑的愿望，以便教師及時調(diào)整其后課堂教學的內(nèi)容、難度、和深度的把握。
“聽力”訓練由兩大部分組成，分別安排在“聽力”（Listening）和“綜合技能”（Integrating Skills）兩個部分。前者又由兩部分組成，第一部分為紀念“世界地球日”活動上的講話，闡述了保護水資源的必要性和緊迫性。第二部分圍繞保護水資源的主題，介紹了如何保護水資源的具體措施；后者，作為綜合語言運用部分，聽力內(nèi)容主要為其后的寫作作為鋪墊，除了敏銳捕捉語言信息以外，學生還需要了解發(fā)言稿的開篇、論證、以及結(jié)束。
“閱讀”（Reading）著重介紹世界地球峰會的由來，詳細描述了2002年南非約翰內(nèi)斯堡地球峰會的召開情況，展示了“可持續(xù)發(fā)展”這一主題，會上大多數(shù)代表所涉及的“世界三大殺手（被污染了的飲用水、簡陋的衛(wèi)生設(shè)備和空氣污染，以及貧困、戰(zhàn)爭、和暴亂，指出世界的順利發(fā)展，取決于各國的和平相處、互相合作、互相促進、共同進步，最后文章還闡述了世界地球峰會的作用和意義。
“語言學習”（Language Study）要求學生利用構(gòu)詞法的知識，靈活運用詞形變化進行正確運用，在第二部分要求學生正確辨別－ly結(jié)尾詞的詞性。
“語法”（Grammar）通過對倒裝形式的總結(jié)，全面了解倒裝的具體結(jié)構(gòu)和應(yīng)用，結(jié)合句型轉(zhuǎn)換和選詞填空練習，幫助學生掌握這一語法現(xiàn)象。
“綜合技能”（Integrating skills）采用高一課本中未曾出現(xiàn)過的展示方式，選用聽力方式展示寫作模式，通過口頭討論等方式，鞏固學生對本單元知識的掌握，從而有效地指導學生進行寫作練習， 并通過Unit 2中的checklist對所寫的書面表達進行修改。

答案為B。 Not until 引導從句位于句首，后面的主句要倒裝。
答案為B。句中的nor引出部分倒裝結(jié)構(gòu)，表示"也不"。由 so, neither, nor引導的倒裝句，表示前一情況的重復出現(xiàn)。其中, so用于肯定句, 而 neither, nor 用在否定句中。 典型例題
- Why can't I smoke here?
- At no time _______ in the meeting-room.
A. is smoking permitted B. smoking is permitted
C. smoking is it permitted D. does smoking permit
答案A. 這是一個倒裝問題。當否定詞語置于句首以表示強調(diào)時，其句中的主謂須用倒裝結(jié)構(gòu)。這些否定詞包括no, little, hardly, seldom, never, not only, not until等。本題的正常語序是 Smoking is permitted in the meeting-room at no time.
Not until the early years of the 19th century _______ what heat is.
A. man did know B. man know
C. didn't man know D. did man know
答案D. 看到Not until…的句型，我們知道為一倒裝句，答案在C，D 中選一個。改寫為正常語序為，Man did not know what heat is until the early years of the 19th. 現(xiàn)在將not提前，后面就不能再用否定了,否則意思就變了。 典型例題
No sooner _______ than it began to rain heavily.
A. the game began B. has the game begun
C. did the game begin D. had the game begun答案D. 以具有否定意義的副詞放在句首時，一般采用倒裝句(謂語前置)。這類表示否定意義的詞有never, seldom, scarcely, little, few, not, hardly, 以及not only…but (also), no sooner…than, hardly… when scarcely… when等等。
注意：只有當Not only… but also連接兩個分句時，才在第一個分句用倒裝結(jié)構(gòu)。如果置于句首的Not only… but also僅連接兩個并列詞語，不可用倒裝結(jié)構(gòu)。
Not only you but also I am fond of music.
About World Day for Water

States were invited to devote the Day, as appropriate in the national context, to concrete activities such as the promotion of public awareness through the publication and diffusion of documentaries and the organization of conferences, round tables, seminars and expositions related to the conservation and development of water resources and the implementation of the recommendations of Agenda 21.

IV. EARTH SUMMIT
In 1992, more than 100 heads of state met in Rio de Janeiro, Brazil for the first international Earth Summit convened to address urgent problems of environmental protection and socio-economic development. The assembled leaders signed the Convention on Climate Change and the Convention on Biological Diversity, endorsed the Rio Declaration and the Forest Principles, and adopted Agenda 21, a 300 page plan for achieving sustainable development in the 21st century.
The Commission on Sustainable Development (CSD) was created to monitor and report on implementation of the Earth Summit agreements. It was agreed that a five year review of Earth Summit progress would be made in 1997 by the United Nations General Assembly meeting in special session. This special session of the UN General Assembly took stock of how well countries, international organizations and sectors of civil society have responded to the challenge of the Earth Summit.
