摘　　要：基于功能充分性框架,以48名英语专业二年级本科生为研究对象,探讨任务复杂度对二语写作中不同语言层面(局部、整体、篇章)衔接手段使用的影响。结果显示:任务复杂度对局部衔接的词汇重叠有显著影响,但对连接词和语义相似性影响不显著;在整体衔接层面,任务复杂度显著影响词汇重叠和同义重叠,复杂度提高时词汇重叠减少,同义重叠增加;在篇章层面,任务复杂度显著降低时序性衔接、代词衔接和语义相似性。结果表明,任务复杂度通过影响衔接与连贯维度制约功能充分性的发展,支持“竞争假设”。研究结果有助于教师更好地设计二语写作课堂教学任务,帮助学习者提高写作水平。This study,grounded in the framework of functional adequacy,investigates the impact of task complexity on the use of cohesive devices across different linguistic levels(local,global,and textual)in L2 writing.The participants were 48 second-year English majors.The findings reveal that task complexity significantly affects lexical overlap in local cohesion,with no significant impact on the use of connectives or semantic similarity.At the global level,task complexity significantly influences lexical overlap and synonym overlap,with increased complexity reducing lexical overlap while enhancing synonym overlap.At the textual level,higher task complexity leads to significant reductions in temporal cohesion,pronominal cohesion,and semantic similarity.These results suggest that task complexity constrains the development of functional adequacy by affecting the dimensions of cohesion and coherence,supporting the"Trade-off Hypothesis".The findings offer valuable insights for teachers in designing classroom tasks to enhance L2 writing instruction and help learners improve their writing skills.
