摘要：This paper aims to investigate Korean learners’ interlanguage with respect to the production of English bi-clausal wh-questions. One hundred seven adult Korean-speaking learners of English in three proficiency groups took part in a production task designed to elicit English bi-clausal wh-questions. The study specifically asked what interlanguage structures Korean EFL learners would produce and whether the structures would change as learners’ English proficiency advances. The results revealed that Korean EFL learners produced a range of alternative bi-clausal structures, including wh-scope marking, silent scope marking, wh-scope marking with embedded wh-in-situ, L1 clause order, and wh-about-wh type constructions. Comparison of three proficiency groups showed that as the learners’ English proficiency increases, they tend to produce an increasing number of derivationally more complex alternatives. It is argued that derivational complexity plays a role in the developmental process of Korean EFL learners’ interlanguage for bi-clausal wh-questions.
