Middle school students are also enthusiastic participants. They organize activities in their spare time, and take this opportunity to make friends, broaden their horizons, cultivate team spirit and communication skills. This section describes a bird watching activity organized by several middle school students of Bird watching Club. It aims to stimulate students' interest, improve their understanding of bird watching activities, and use the language structure of “being used for; in order to, so as to, to, so that, in order that ” to express the purpose for communication and discussion.1.

1. 完成文本主要信息填空(斜體字部分設(shè)空):As a witness to farmers’ poor harvests and even a severe shortage of food, Yuan Longping was determined to devote his life to tackling this crisis. After graduation, he realized that what farmers needed most was to boost yields in the fields. Yuan was convinced that the answer lay in the creation of hybrid rice, one characteristic of which is that it usually achieve higher output than conventional crops. However, it was no easy job. The first difficulty he needed to overcome was scientists’ general assumption that this could not be done. Through trial and error, Yuan managed to generate this incredible crop. It is estimated that about 60 percent of domestic rice consumption in China was comprised of crops generated from Yuan’s hybrid strains. His innovation has enabled Chinese farmers to considerably expand their output and helped feed the world. Unwilling to retire early to a life of leisure and unconcerned about celebrity or fortune, Yuan continues to turn one vision after another into realities.2. 模仿寫作:Do some research via the Internet and introduce another agricultural scientist, Chen Risheng(陳日勝), using the structure, expressions and writing techniques you have learnt from the text “A Pioneer for All People”.【設(shè)計(jì)意圖】任務(wù)1是對(duì)文本內(nèi)容和詞匯學(xué)習(xí)成效的檢測(cè)。任務(wù)2借助文本中學(xué)到的詞匯和寫作手法仿寫另一位科學(xué)家,提升學(xué)生遷移運(yùn)用詞匯、文體結(jié)構(gòu)和寫作方法的能力。

師:很好。由于存在地球大氣圈、地球水圈和地表的礦物,在地球上這個(gè)合適的溫度條件下,形成了適合于生物生存的自然環(huán)境。人們通常所說的生物,是指有生命的物體,包括植物、動(dòng)物和微生物。據(jù)估計(jì),現(xiàn)有生存的植物約有40萬種,動(dòng)物約有110多萬種,微生物至少有10多萬種。據(jù)統(tǒng)計(jì),在地質(zhì)歷史上曾生存過的生物約有5億~10億種之多,然而,在地球漫長(zhǎng)的演化過程中,絕大部分都已經(jīng)滅絕了?,F(xiàn)存的生物生活在巖石圈的上層部分、大氣圈的下層部分和水圈的全部,構(gòu)成了地球上一個(gè)獨(dú)特的圈層,稱為生物圈。生物圈是太陽系所有行星中僅在地球上存在的一個(gè)獨(dú)特圈層。課堂小結(jié):地球所有的外部圈層是相互滲透、相互影響,甚至相互重疊的,在太陽和人類生活的參與下,整個(gè)地球生機(jī)盎然;同時(shí),它們起著保護(hù)地球的作用,可以減弱太陽和宇宙輻射對(duì)地表的影響,減少宇宙中的隕石對(duì)地球表面的撞擊。外部各圈中的物質(zhì)運(yùn)動(dòng)和循環(huán),是促使地表物質(zhì)和形態(tài)演變的重要?jiǎng)恿Α?/p>
科學(xué)家預(yù)測(cè),就地區(qū)而言,位于低緯度的大部分國(guó)家,農(nóng)作物的產(chǎn)量將減少;而位于高緯度的國(guó)家,農(nóng)作物產(chǎn)量有可能增加。由于不少發(fā)展中國(guó)家位于低緯度地區(qū),因此,氣候變化的這種區(qū)域差異性,可能會(huì)使發(fā)展中國(guó)家所面臨的問題更為嚴(yán)峻。板書:3全球變暖將加劇水資源的不穩(wěn)定性與供需矛盾。介紹:全球變暖會(huì)影響整個(gè)水循環(huán)過程,可能使蒸發(fā)加大,改變區(qū)域降水量和降水分布格局,增加降水極端異常事件的發(fā)生,導(dǎo)致洪澇、干旱災(zāi)害的頻次和強(qiáng)度增加,以及地表徑流發(fā)生變化。隨著徑流減少,蒸發(fā)增強(qiáng),全球變暖將加劇水資源的不穩(wěn)定性與供需矛盾。轉(zhuǎn)折:既然全球變暖會(huì)引起很多不利影響,那么作為人類應(yīng)如何面對(duì)這一挑戰(zhàn)呢?這就是我們要討論的第三個(gè)問題。板書:三、氣候變化的適應(yīng)對(duì)策討論:請(qǐng)大家閱讀結(jié)合教材P53氣候變化的適應(yīng)對(duì)策部分討論人類應(yīng)如何面對(duì)全球變暖這一問題 呢?
