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。

    人教版新課標(biāo)高中物理必修1彈力教案2篇

    一般情況下,凡是支持物對(duì)物體的支持力,都是支持物因發(fā)生形變而對(duì)物體產(chǎn)生彈力。所以支持力的方向總是垂直于支持面而指向被支持的物體。例1:放在水平桌面上的書(shū)書(shū)由于重力的作用而壓迫桌面,使書(shū)和桌面同時(shí)發(fā)生微小形變,要恢復(fù)原狀,對(duì)桌面產(chǎn)生垂直于桌面向下的彈力f1,這就是書(shū)對(duì)桌面的壓力;桌面由于發(fā)生微小的形變,對(duì)書(shū)產(chǎn)生垂直于書(shū)面向上的彈力f2,這就是桌面對(duì)書(shū)的支持力。學(xué)生分析:靜止地放在傾斜木板上的書(shū),書(shū)對(duì)木板的壓力和木板對(duì)書(shū)的支持力。并畫(huà)出力的示意圖。結(jié)論:壓力、支持力都是彈力。壓力的方向總是垂直于支持面而指向被壓的物體,支持力的方向總是垂直于支持面而指向被支持的物體。引導(dǎo)學(xué)生分析靜止時(shí),懸繩對(duì)重物的拉力及方向。引導(dǎo)得出:懸掛物由于重力的作用而拉緊懸繩,使重物、懸繩同時(shí)發(fā)生微小的形變。重物由于發(fā)生微小的形變,對(duì)懸繩產(chǎn)生豎直向下的彈力f1,這是物對(duì)繩的拉力;懸繩由于發(fā)生微小形變,對(duì)物產(chǎn)生豎直向上的彈力f2,這就是繩對(duì)物體的拉力。
