学生活动:复述课文,巩固词汇。

教师活动:引导学生简要复述袁隆平的主要事迹,描述他研究杂交水稻的原因、困难、结果和影响,以及他扎根土地、不断创新的高尚品质。可参考以下范例:

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 realised 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 achieves 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 intense effort, Yuan managed to generate this incredible crop. It is estimated that about 60 percent of domestic rice consumption in China is 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.
