English courses should not only lay a good foundation for language, but also pay more attention to the training of practical language skills, especially the ability to use English to deal with daily and foreign business activities. Higher vocational college students who are relatively weak in their basic English writing are particularly prominent,far from the regulated requirements. Because of the poor basic learning ability of higher vocational college students, it is very important for teachers to supervise and get feedback. But the ratio of students to English teachers in some higher vocational colleges has reached 130 : 1, so it is becoming more and more important for teachers to adopt computer aided correction composition system.展开更多
