Through researching the process of students’ looking at the picture composition by audio thinking, Wen Qiufang and Guo Cahunjie found that students who have high foreign language writing ability (28% dependent in mother tongue) is less dependent in mother tongue than those with small ability (80% dependent in mother tongue) (Wen Qiufang&Guo Chunjie, 1998: 45). Because most of the students have firmly grasped the mother tongue when they involved in English, their ability of mother tongue make them use native language strategy to produce the article content and discourse structure in the English writing, and they express the content of the native language conception in English.来.自/优尔论|文-网www.youerw.com/
