本文运用实证研究的方法，探讨任务驱动下的语块教学训练模式在大学英语教学中的有效性。该模式最根本的特点就是“以任务为驱动力、语块习得为主线、教师为主导、学生为主体”。该模式将任务教学法与语块教学法有机地结合起来，有效地促进了学生的学习主动性，在提高学生的全面英语综合运用能力方面取得了显著效果。此外，还进行了为期一年旨在证明该训练模式的有效性实验研究。实验结果表明实验班的听读写译能力与对照班相比存在显著性差异。相关问卷调查结果显示，该模式有助于培养学生的语言内化能力，增强了学习的主动性，减少了对教师的依赖性。

This experimental study explores the effectiveness of the Task-driven Chunk-based Training Model (TCTM), whose fundamental characteristics are task-driven, chunk-based, teacher-guided and student-centered. With the organic integration of different tasks into chunk-based approach, this training model effectively promotes learner autonomy in students and thus contributes to the evident improvement of students’ comprehensive language ability. In addition, a one-year experiment was carried out to prove the effectiveness of the training model. The results show that the experimental group made significant improvement in their listening, reading, writing and translating abilities. The relevant questionnaire result shows that the model also helps to develop learners’ language internalization ability and their learning activeness, and thereby their dependence on teachers lessens.
