摘　　要：混合式教学是当前大学英语教学改革的主要方向,但学界针对不同混合式教学的有效性问题却鲜有讨论。本研究以200名大一学生为研究对象,探究混合式教学和二语水平对其英语句重音感知准确性的影响。研究发现:1)不管是高水平二语者还是低水平二语者,"显性+隐性"方式的促学效应都要优于"隐性+显性"方式;2)不同混合比例在高水平二语者身上存在差异,高频次输入的促学效应要好于低频次输入;3)混合方式和混合比例在低水平二语者身上存在交互效应。研究结果表明,"显性+隐性"的混合方式更适合中国英语学习者,混合比例的促学效应则是有条件的。Blended instruction is the main direction in the current college English teaching reform,but there is little discussion on its effectiveness.By using 200 freshmen as subjects,the present study examined howblended instruction and language proficiency affected their perception of English sentence stress.The results showed that:1)the"explicit+implicit"pattern was more conducive to perception accuracy than the"implicit+explicit"pattern for both high language proficiency learners and lowlanguage proficiency learners;2)Blended ratio differed only for high language proficiency learners,and the acquisition effect of high frequency input was better than that of the lowfrequency input;3)Blended patterns and blended ratios have an interactive effect on lowlanguage proficiency learners.The results also showed that the"explicit+implicit"pattern was more suitable for Chinese English learners,while the effectiveness of blended ratio was conditional.
