1. 完成文本主要信息填空（斜体字部分设空）：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. 模仿写作：Do some research via the Internet and introduce another agricultural scientist, Chen Risheng（陈日胜）, using the structure, expressions and writing techniques you have learnt from the text “A Pioneer for All People”.【设计意图】任务1是对文本内容和词汇学习成效的检测。任务2借助文本中学到的词汇和写作手法仿写另一位科学家，提升学生迁移运用词汇、文体结构和写作方法的能力。
