基于输出假设提高英语写作能力的实证研究*

加拿大语言学者 Swain 认为语言输入是必要的，要使学习者达到较高的外语水平，紧靠可理解输入是不够的，还需要可理解性输出。外语学习必须输入与输出有效结合，才能增强学习效应。语言输入与输出关系既表现为前者促进后者，还表现为后者促进前者。为使使语言输入与输出有效结合，通过读后总结、读后仿写、读后改写、读后续写等多种形式的读写结合进行了教学实验，结果表明，加大语言输出能有效提高学生的写作能力。

An Empirical Study of Improving Writing Ability Based on the Output Hypothesis

Canadian Linguist Swain maintained that language input is necessary, but not enough to reach a higher level of foreign language learning which depends also on comprehensible output. Only by integra-ting language input and output can the learning effect be strengthened. Language input and output are mu-tually improved. On this basis, the paper made an attempt to improve writing ability by various forms such as post-reading summary wiring, post-reading imitation, rewriting and continue writing. The result shows that wring ability can be improved effectively by enhancing language output.
