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(xiě)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(xiě)作手法仿寫(xiě)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(xiě)作方法的能力。

【概括】天體是在不斷的運(yùn)動(dòng)著的。運(yùn)動(dòng)著的天體互相吸引和互相繞轉(zhuǎn)，從而形成天體系統(tǒng)?！景鍟?shū)】四、天體系統(tǒng)【啟發(fā)】天體系統(tǒng)有大有小，大的天體系統(tǒng)又可包含許多小的天體系統(tǒng)。剛才同學(xué)們提到的三個(gè)天體系統(tǒng)之間是如何包含的呢？（銀河系含太陽(yáng)系，太陽(yáng)系含地月系）【掛圖講解】地月系只有兩個(gè)天體，地球和月球，它們之間的平均距離為384401千米；太陽(yáng)系則包括太陽(yáng)、九大行星、數(shù)十顆衛(wèi)星及其它天體，整個(gè)太陽(yáng)系的直徑至少100億千米以上；而銀河系則擁有2000多億顆太陽(yáng)恒星及恒星系統(tǒng)，包括了我 們用肉眼能看到的所有恒星，其主體部分的直徑達(dá)7萬(wàn)光年，太陽(yáng)就處于距銀河系中心2.3萬(wàn)光年的位置上?！局v解】銀河系已如此龐大，是否 就是最大的天體系統(tǒng)呢？是否就是我們的宇宙呢？還遠(yuǎn)遠(yuǎn)不是。利用天文望遠(yuǎn)鏡，我們可以觀測(cè)到在銀河系之外，還有約10億個(gè)類似的天體系統(tǒng)，它們被統(tǒng)稱為河外星系。
人教版高中地理選修2百萬(wàn)移民及其安置教案
三峽庫(kù)區(qū)農(nóng)村移民安置根本出路是通過(guò)發(fā)展大農(nóng)業(yè)來(lái)解決耕地不足，不應(yīng)盲目開(kāi)墾荒坡地，防止產(chǎn)生新的水土流失，盡量避免生態(tài)環(huán)境惡化。2、就地后靠，就近安置模式三峽庫(kù)區(qū)淹沒(méi)區(qū)線狀分布的受淹特點(diǎn)有別于一般水庫(kù)淹沒(méi)區(qū)的片狀分布，使得庫(kù)區(qū)移民具有相對(duì)分散的特點(diǎn)，且淹沒(méi)涉及的356個(gè)鄉(xiāng)鎮(zhèn)沒(méi)有一個(gè)被全淹，甚至全淹的村也很少，這有利于移民在本縣甚至本鄉(xiāng)就近后靠安置，避免了水庫(kù)移民大量外遷、遠(yuǎn)遷所造成的種種困難和后遺癥。三峽移民搬遷大多可以就地后靠，就近安置，這是三峽移民的一大特色。就近后靠安置的優(yōu)點(diǎn)是不離本鄉(xiāng)本土，移民容易接受，且避免了移民大量外遷、遠(yuǎn)遷所造成的困難和后遺癥；缺點(diǎn)是容易對(duì)當(dāng)?shù)氐纳鷳B(tài)環(huán)境造成過(guò)大的壓力，如過(guò)度開(kāi)墾坡地、破壞植被、加劇水土流失等。3、工程周期長(zhǎng)，可從容安置移民三峽工程建設(shè)周期長(zhǎng)（1994年～2009年，共17年），使得移民安置能夠及早進(jìn)行，可以從容安置移民的生產(chǎn)和生活。
人教版高中語(yǔ)文《短新聞兩篇》教案
羅森塔爾突破了“客觀報(bào)道”“零度寫(xiě)作”的框框，把自己和其他參觀者在奧斯維辛訪問(wèn)時(shí)的感受當(dāng)做文章的主要內(nèi)容來(lái)寫(xiě)，傳達(dá)出每一個(gè)良知者的共同心聲。教師總結(jié)：細(xì)節(jié)描寫(xiě)是耐人尋味的。文章沒(méi)有陰森恐怖的鏡頭，沒(méi)有血腥的畫(huà)面，只是重現(xiàn)了新聞的事實(shí)真相，但透過(guò)細(xì)節(jié)卻能引發(fā)人們對(duì)生命，對(duì)人性的思考。在作者看似平靜的敘述中抒發(fā)了對(duì)德國(guó)納粹殘酷暴行的沉重控訴，更表達(dá)了作者對(duì)自由、和平與祥和的向往四、拓展延伸：《奧斯維辛沒(méi)有什么新聞》這一作品本身的價(jià)值在哪？社會(huì)價(jià)值又在哪，能不能從這兩個(gè)角度思考，幾人合作試寫(xiě)一段頒獎(jiǎng)詞？范例：《奧斯維辛沒(méi)有什么新聞》突破新聞“零度寫(xiě)作”原則，著眼細(xì)節(jié)，以冷峻的視角，深沉地描述了今天的奧斯維辛集中營(yíng)紀(jì)念館。在恐怖與快樂(lè)、戰(zhàn)爭(zhēng)與和平、歷史與現(xiàn)實(shí)的反差中，它召喚起人們關(guān)于災(zāi)難的記憶、關(guān)于生命的思考、關(guān)于人性的自省。它的發(fā)表充分地表現(xiàn)了一個(gè)新聞?dòng)浾叩氖姑?，更以迫人的力量震撼生者的心，成為新聞史不朽的名篇?/p>
