College English is a compulsory public basic course in China's higher education, but in order to learn English well and improve the overall English ability, we can't take "English" or simply treat it as a course, because English is a language. At the moment when everyone is facing the challenge of globalization while trying to integrate with the world, the expectation of society for "English" far exceeds that for a course. Therefore, college English courses have touched the hearts of so many people before, from government officials to ordinary people, putting pressure on universities in English teaching. English is a course, but if you want to learn English well, you can't rely entirely on four classes a week. To understand the essence of language and respect the law of language acquisition, we should not only improve classroom teaching, but also develop students' autonomous learning personality. Therefore, we should develop a multimedia network teaching system, and with the help of these educational software, students can learn English.
