【摘要】 词块应用能力是衡量二语写作质量的一个重要指标，其发展是一个日积月累的过程。本研究以本族语者的高频四词词块为参照，追踪了88名中国大学英语专业学生连续两年的议论文写作语料，探究写作词块在结构、功能、准确性等方面的发展特征。结果表明:虽然两年中词块与本族语者相比整体上仍存在显著差距，学生词块使用的准确性提高不显著，且持续存在过度泛化问题，但呈现出应用更广泛、类型分布更接近于英语本族语者表达习惯等趋势。本研究对写作教学和学习有较强的借鉴作用。更多还原

【Abstract】 Good use of lexical bundles contributes to L2 writing quality, but their acquisition is a longterm journey. In this study, 88 English-major learners’ use of bundles in argumentative essays from their first to second academic years were collected and comparatively analyzed with the high-frequency bundles by English native speakers’ academic writings. The purpose is to explore the characteristics of students’ bundle development in terms of structure, function and accuracy. The results show that the significant gap of bundle use between the target sample and native speakers still remains even after two years’ training. The same is true to the accuracy improvement. In addition, writings from both first and second years may exhibit the over-generalization of specific bundles. In spite of this, their extensive use and distribution of bundles in writing become oriented towards native-like. Further recommendations are made for writing instruction and learning from this study.更多还原
