The traditional college English teaching is teacher-centered, mainly based on the Text Books. Teachers impart the language knowledge and very little knowledge about culture, usually by cramming teaching method while the students accept knowledge passively. The traditional teaching mode provides very limited language and cultural knowledge and practical activities. In the traditional teaching mode, the input and output of language and cultural knowledge are very limited as well as the activities of cross-cultural communication are very limited, so, students lack enthusiasm of study, not mention the critical thinking ability, team cooperation and practical ability. Therefore, it is necessary to reform the traditional college English teaching mode in order to realize the rich humanistic connotation. With the development of Science and Technology, Computer and Network Information Technology are widely used in college English teaching; traditional teaching methods have been greatly changed. Present days, college students, as growing up in the times of highly integrated development of modern information technology and education, they have long been used to learning by reading screen, reading pictures, watching videos and so on.

Compared with the traditional college teaching, the huge information provided by network and various links related to teaching software greatly make up for and expand the deficiency of traditional textbooks in content and form, provide students with broad learning space, and increase students' language input [2] . Pre-class, students collect the texts, pictures, videos, audios and other information on internet, select the materials related to the unit theme and the content of the unit to be integrated into PPT. Teachers set up Listening Practice Test, Vocabulary Test and Reading Comprehension Test on the network-based teaching platform to check the students' learning. Teachers inspire the student to analyze, discuss and seek for solution to the problems. While in class, the students present and display their PPT on the computer teaching platform. The group members share their plans on process of learning tasks, and difficulties encountered, solutions to difficulties and so on. After-class, teachers will deliver their own teaching content, theme-related supplementary materials and videos on the teaching platform for students to strengthen the unit theme learning. After class, the teacher will deliver the unit topic-related composition on the computer network teaching platform. Combining computer marking and teacher marking, the teacher selects several pieces of compositions to display them on the computer network teaching platform. Each team will write their own comments on these compositions. Assigning each member with different tasks, the team work together to translate selected passages or to dub classical film and television clips or to sing English songs or to tell English stories or play English dramas and so on. Then they need to record the videos of the above projects and upload their works on computer network teaching platform.

In college English teaching, cultural communication should be two-way and interactive; both input of English culture and the output of Chinese culture should be given same attention. The concept of culture is very broad, covering various aspects of human life. Culture is not only the process of human vertical historical development, but also the modes and activities of human horizontal social life. In the face of the complex systems of English culture and Chinese culture, students are easily confused and at a loss.

Actually, many aspects on culture itself are open topics, everyone may have different opinions on each cultural topic. Students will also share reading responses and learning experience on the network teaching platform. Through the reading of the recommended books, the MOOCs, the micro-class cultural learning, the discussion and sharing the experience, students can have an overall grasp of the Chinese culture and the English culture historical development process, so as to have a general grasp of the development course of Chinese culture and English culture.

Chinese culture and English culture have their own unique living environment [5] ; they have similarities and differences. In learning English culture and Chinese culture with the method of contrast, students can deepen their understanding of differences of Chinese and English culture, and learn to respect and appreciate different cultures. Culture is not static; culture is constantly changing and communicating with other cultures. The comparison between Chinese culture and English culture is a broad and systematic cultural system. Therefore, it is far from enough for students to study only in classes, and extensive literature reading, micro-class and MOOCs study should be carried out in combination with students' pre-class study. This kind of study helps students to have a deep understanding of cultural phenomena, to look dialectically at the cultural viewpoints, and to form a way to view cultural phenomena in an all-round way.

Each team is required to present a basic overview and brief description of the group's activities on the internet-based teaching platform, then the learners need to complete the evaluation of their own performance on the teaching platform. The team members need to evaluate the performance of the team members in the process of collaboration, and the learners need to evaluate each other's performance. The teacher needs to give evaluation to each team and each learner. Then, comprehensive evaluation is formed from combining the evaluations of each team, every learner and teacher. The tests on listening comprehension, vocabulary and reading comprehension published on the computer network teaching platform are mainly based on marks given by computer marking. Students upload their team works of translation exercises, video dubbing, singing English songs, telling English stories, English dramas and other assignments on the computer network teaching platform. Students review these uploaded works. Combine peer review, self-evaluation, team group's comments with teachers' marking to make a comprehensive evaluation.
