Writing is an indispensable part of college English learning. However, the present situation of college English writing teaching in China is far from satisfactory. Although many studies have been carried out concerning college English writing and teaching, very few of them explored the writing strategies adopted by non-English majors in their composing process. It is expected that the investigation of writing strategies can help to discover what students actually do in composition writing, and consequently provide some insights into the teaching of college English writing. The research question addressed in this study is 'What strategies are used by non-English majors in their writing process?' The descriptive analysis of the results showed that Chinese non-English majors did employ diverse strategies in their composing process. Among the six strategy groups, memory strategies were the most frequently used. Compensation strategies were the next, while affective strategies were given the least attention. As for the specific writing strategies, the strategy of using discourse connectives was used most frequently by students, the strategy of discussing feelings with others was the least among their choice. These findings provided much insight into college English writing and teaching.
