本文通过检索BROWN中存在句的分布情况得出在本族语中,存在句的使用特点。然后对比检索SWECCL中WECCL所显示出的中国英语学习者存在句中所存在的问题。发现中国英语专业学生部分现在时态的句式使用过度,而部分过去时态的句式使用过少;又通过分析存在句使用的总体分布特征的不同之处,发现中国英语专业学生偏爱现在时的句型,从而支持验证了母语负迁移理论和输出假设。
In this paper, we find the usage characteristics of existential sentences in native languages by retrieving the distribution of existential sentences in BROWN. Then we compare the problems existing in the Chinese EFL learners’ existential sentences displayed by WECCL in SWECCL. We found that the present tense of Chinese EFL students is partially overused while the sentences of some past tense are used less than others. By analyzing the differences in the overall distribution of existential sentences, we find that Chinese EFL students prefer the present tense , Thus supporting the verification of negative transfer theory and output hypothesis.
