4.思維品質(zhì)能夠根據(jù)數(shù)據(jù)圖表分析氣候變化的趨勢(shì)，找到問(wèn)題產(chǎn)生的源頭與解決問(wèn)題的對(duì)策；能夠區(qū)分關(guān)鍵信息和非關(guān)鍵信息；能夠識(shí)別身邊的環(huán)境問(wèn)題，運(yùn)用所學(xué)知識(shí)提出解決方案，增強(qiáng)解決實(shí)際問(wèn)題的意識(shí)和能力.
二、教學(xué)重點(diǎn)、難點(diǎn)
1 .教學(xué)重點(diǎn)：
（1）引導(dǎo)學(xué)生觀察并掌握說(shuō)明文的結(jié)構(gòu)特征；
（2）指導(dǎo)學(xué)生用示意圖展示溫室效應(yīng)的原理；
（3）啟發(fā)和鼓勵(lì)學(xué)生改變生活方式，減少碳排放，同時(shí)提出改善性的建議與對(duì)策。
2.教學(xué)難點(diǎn)：指導(dǎo)學(xué)生用示意圖展示溫室效應(yīng)的原理；
三、教學(xué)方法 任務(wù)型教學(xué)法、小組合作探究法等。
四、教具準(zhǔn)備 多媒體，黑板
五、教學(xué)過(guò)程
課前學(xué)生學(xué)習(xí)活動(dòng)設(shè)計(jì)：課前讓學(xué)生們預(yù)習(xí)單詞和課文，上網(wǎng)了解一些由于全球變暖而造成的極端天氣得新聞報(bào)道、圖片或視頻。
Pre-reading Watch a video
Discuss : What are they talking about Is climate change really a problem
What consequences may global warming bring about
設(shè)計(jì)意圖：通過(guò)視頻導(dǎo)入新課，引入 climate change 這一話題，圍繞此話題，讓學(xué)生開(kāi)展“頭腦風(fēng)暴”。
Show the learning objectives of this class
Find the causes, consequences of global warming and solutions to it;
Use diagrams to figure out the logic of the passage;
Write a post to call on people to stop global warming and save polar bears.
Fast reading
Read the text quickly and Focus on the structure
Divide the passage into 4 parts and match the main idea with each part.
The cause of the increase in the global average surface temperature.
The solutions to reducing greenhouse gas emissions
The evidence and effect of dramatic climate change in global climate.
The consequences of rise in temperature
Underline the topic sentence of each paragraph and choose the best answer.
1. What type of writing is this passage
A. Argumentative writing（議論文）B. Narrative writing（記敘文）
C. Expository writing（說(shuō)明文）D. Advertising writing（廣告）
設(shè)計(jì)意圖：本活動(dòng)旨在引導(dǎo)學(xué)生觀察并掌握說(shuō)明文的結(jié)構(gòu)特征，引導(dǎo)學(xué)生通過(guò)運(yùn)用略讀閱讀策略，尋找主題句并根據(jù)主題句對(duì)段落大意進(jìn)行概括，整體把握文本內(nèi)容，提升概括能力。
Careful reading
Read para by para
Part 1 (para 1-2) Evidence The following reasons account for the death of the polar bear, with one influencing another.
Read para 2 carefully and put them in a correct logical order.
A low sea-ice level B starved to death C had to travel greater distances to find food
D bears could not hunt E climate change F its dead body found what is the real cause
設(shè)計(jì)意圖：引導(dǎo)學(xué)生關(guān)注文本中事件的因果關(guān)系。
Part 2 (Para.3) cause Read para 3 carefully and fill in the diagram to explain how the greenhouse
effect works.
設(shè)計(jì)意圖：讓學(xué)生學(xué)會(huì)利用圖表厘清事物發(fā)生的因果關(guān)系，解釋一個(gè)新的想法或概念，不僅可以讓學(xué)生更清楚地看到問(wèn)題，而且可以展示學(xué)生的創(chuàng)造性思維和解決問(wèn)題的能力。
Part 3 (para 4 ) Consequence Read para4 ,then think this question:
Why did the author mention the climate scientists’ warning
Part 4 Solutions Read Para.5 carefully to finish the following chart
