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。
