2、chers in China have been focusing on fluency and accuracy exclusively and have neglected complexity. Accordingly, there is the situation that students only pursue fluency and accuracy, which results in their pacing aroun

3、d a lower level of oral proficiency. Their speaking lacks color and variety and could hardly meet higher communicative demand. This negligence of complexity in teaching may contribute to the disjoint between what student

4、s learn and what they put into actual use. How to convert “passive” knowledge into “active” ones is a problem that has been pestering many Chinese English learners and also teachers for a long time. More attention on lan

5、guage complexity could drive students to apply more expressions and sentence patterns into actual use, which would help to improve the current situation. Therefore, this research paper investigated the effects of task ty

7、Huazhong University of Science and Technology. Fourteen college non-English sophomores participated in the study. After analyzing their oral performance under four tasks which cross two task types (monologic and interact

8、ive tasks) and two levels of task complexity (simple version and complex version), the study found task type and task complexity significantly affected certain aspects of oral performance. Task type significantly affects

9、 learners’ oral complexity on sentence length and their output. Concerning task complexity, it is necessary to distinguish between monologic tasks and interactive tasks. Under monologic task type, task complexity signifi
