本文以沙漏模式为框架,将教学分为语言呈现阶段、强调重点阶段和练习活动阶段。以大学英语中比尔·盖茨的一篇演讲作为实例,阐述了英语教师在上下宽的沙漏阶段应用海纳百川的内容让学生进入某种积极的情绪体验;在细的瓶颈部分,应强调语言知识的重难点。上下和中间的三个阶段像沙漏瓶颈一样,相得益彰,共同完成教学目的。 This paper takes the hourglass model as the framework, divides teaching into the language presentation phase, emphasizes the key phase and the practice activity phase.

In the thin bottleneck, the emphasis should be placed on language knowledge Heavy difficulty. Up and down and the middle of the three stages like the bottlenecks of the same hour, complement each other to accomplish the teaching purpose.
