摘要本文通过语料库机切的研究方法，讨论了中国高等院校的英语二语习得者在写作中使用不定式组合情况，我们统计带TO不定式在句子中的不同位置出现的频率统计数据，继而讨论了了造成这种频率分布的可能成因。本文使用了正则表达式的方法来匹配一个带标记的语料库，然后使用相关软件来计算相关不定式组合的情况。为了更好分析其特点，本文进行了一些必要的统计工作。通过本文我们发现在英语专业学生和非英语专业学生，他们在句子中使用不定式的情况存在差别。76656
Abstract This paper discusses about the infinitive colligations used by Chinese ESL college students, by using the machine cut method, we can calculate the frequency of each type of the presence of the TO infinitive in different places of a sentence, and followed by the discussion of the possible causes of this kind of distributions。 This paper employs the regular expressions to match the possible word tags in a tagged corpus。 Then we use the software to calculate the frequency of each type of the listed infinitive colligations, and in order to compare and find their features, this paper goes on doing some statistic works。 As a result, we find that there exist some differences between the English major students and the non-English ones。
