To ensure comparability and internal validity，the ICNALE，i.e.International Corpus Network of Asian Learners of English（Ishikawa，2013），was used as the database for this study.48 sets of learner texts were randomly selected（See Table 1 for the bio-data）.All learners were categorized into four CEFR levels（A2，B1＿1，B1＿2 and B2+）1based on their language test scores（i.e.TOEFL IBT or PBT）.The texts produced by each learner include two essays on two different topics.
