TBLT的中心环节：任务难度与任务分级

摘要

Task-based language teaching is an approach to language teaching organized around tasks. Determining task difficulty and grading tasks are at the core of TBLT implementation. This paper reviews task difficulty as well as the main factors affecting task difficulty from the perspectives of Skehan and Ellis. It explores grading criteria according to task types as well as task difficulty factors. Finally, further research on task difficulty and grading tasks is discussed.%任务型语言教学（TBLT）是以任务为单位组织教学的一种语言教学方法，如何确定任务难度进而对任务分级是教学的中心环节。该文对Skehan和Ellis任务难度体系进行了回顾，从根据任务类型和影响任务难度因素两方面分析讨论任务分级标准，最后对任务难度分级的进一步研究进行了展望。
