Differences in L1 and L2 Academic Writing

Since the first contrastive rhetoric study by Kaplan in 1966, many studies have been produced, and over several decades of development, there have been many contributions gained from previous contrastive rhetoric studies. In this article, many kinds of differences existing in L1 and L2 academic writing have been discussed. I will categorize the differences in three major parts as following: differences in the level of lexicon, differences in the level of sentence, and differences in the level of passage.
