Research on the Explicit and Implicit Instruction of English-Speaking Countries’ Culture for English Majors with the Assistance of Network Platform

With the rapid development of modern society, students majoring in English not only need to strengthen their listening, speaking, reading and writing skills, but also have to learn more about the explicit and implicit culture of English-speaking countries to better improve the level of cultural communication. Against the backdrop of the fast development of the modern Internet technology, teachers are required to make full use of the Internet platform to improve students’ awareness of the explicit and implicit cultures of English-speaking countries. Based on the current situation of explicit and implicit teaching in English culture, this paper gives relevant teaching suggestions in order to guarantee the improvement of oral communication skills of English majors in the future.


Introduction
The cultivation of English majors in undergraduate colleges usually starts from students' listening, speaking, reading and writing abilities, but ignores the educational penetration of British and American culture, which leads to students' weakness in cultural communication. Therefore, in the process of explicit and implicit instruction of English culture, English teachers should fully integrate the history, culture, literary tradition and customs of British and American countries to impart theories, and at the same time, use the current advanced network technology to display British and American culture to students. English study for undergraduate is not only the mastery of basic vocabulary and grammar, but also the study of English culture. Therefore, it is necessary to strengthen the study of British and American culture and use network technology for cultural communication and learning in order to improve students' British and American cultural literacy.

Current situation of culture-related courses in English speaking countries
In the current English major teaching, the curriculum objectives are mainly about the cultivation of students' listening, speaking, reading and writing abilities while ignoring the popularization of British and American culture. In fact, in the process of English communication, the understanding of British and American culture is an important basis for promoting communication [1] . However, cultural infiltration is often ignored in the current teaching of English majors, which is not conducive to the formation of correct values for students. In the process of cultural teaching in English-speaking countries, there are two teaching methods, namely explicit teaching and implicit teaching. Explicit teaching is the ordinary teaching method, while implicit teaching allows students to independently collect materials of British and American cultures and understand the differences between Chinese and western cultures in this process [2] . At present, the teaching process of culture in English-speaking countries is still dominated by traditional explicit teaching, which places too much emphasis on the learning and application of English skills, and reduces the number of students of culture and literature courses, thus affecting the integrity of cultural teaching in English-speaking countries.

Teaching Secondly, teachers tend to focus on teaching grammar in class and ignore the cultural communication links, which results in low learning enthusiasm of students and affects the effect of cultural teaching in English-speaking countries. In addition, when teaching English culture, teachers do not pay attention to the level of teaching. Therefore, students do not have a clear understanding of what they have learned, and the lack of time for combing and understanding leads to the lack of social and cultural understanding in English countries.

make use of the network resources to improve the classroom teaching effect
With the rapid development of Internet technology, many resources are accessible on the Internet. For the explicit and implicit instruction of British and American culture, network technology can better improve the efficiency of cultural collection and dissemination. Downloading and using English resources on the Internet platform can better improve the quality of explicit and implicit instruction of English culture in English-speaking countries [3] . As for foreign culture, Chinese teachers are often unable to have a comprehensive understanding of it, so they can realize the pertinence of teaching through network resources, and search for video or pictures according to the theoretical content of the textbook, so as to deepen students' overall impression on the culture of English-speaking countries. Secondly, the information found on the network platform is actually a supplement to the content of the textbook. The culture of English-speaking countries has a certain breadth, so the appropriate use of network resources in teaching can better expand the dissemination of information, so that the effect of cultural infiltration in the course can be highlighted.

Use the network platform to strengthen the interaction of teaching in and out of class
In the continuous development of educational information technology, English teachers can communicate and learn with students through the network platform in the process of teaching English culture, so as to better answer students' questions [4] . In recent years, the flipped classroom model developed on the Internet platform actually effectively connects teachers and students, breaks the traditional teaching method through communication and enables students to better understand the deep connotation of English culture. In the whole process of online teaching, teachers and students can save time and space through collaborative exploration and interactive communication to improve students' understanding of cultural knowledge of English-speaking countries and achieve in-depth learning effect. English culture has a certain universality and students may often encounter problems in the process of learning, so in this link, [5] English teachers need to use their own professional to give students answers in order to achieve the interactive teaching of English culture.

Use the network platform to complete the task of thematic expansion after class
After learning English national culture, students are often required to absorb and digest what they have learnt in order to reduce the burden of the English teacher. The thematic development task after class will be completed on network platform. The advantage is that a unified evaluation can be realized on the network platform. At the same time, when students working on thematic development task after class, English teachers can give guidance in a timely manner. [6] Finally, the teaching can be summarized through the network platform to achieve the cultural teaching of English-speaking countries. On the other hand, the resources on the network platform are also conducive to the completion of thematic expansion tasks after class. Through group exploration, we can enhance our sense of cooperation, fully mobilize our enthusiasm to learn foreign cultures, improve the efficiency of task completion and deepen our understanding of the society and culture of English-speaking countries. The network platform provides a good basic guarantee for English culture teaching and is more conducive to improving students' cultural vision.

Conclusion
To sum up, the network platform provides a convenient way for the explicit and implicit instruction of English-speaking countries' culture. Teachers must be good at using resources on the Internet to show specific cultural form for students and improving the vitality of the explicit and implicit teaching of English national culture through videos or pictures to better improve students' enthusiasm of learning. In the current teaching process, English teachers should allocate the teaching task reasonably, taking into consideration both the students' ability of listening, speaking, reading and writing training, and their understanding of British and American culture. In this way, teachers can improve students' cognition of the British and American culture through multiple teaching methods to better improve their cultural communication.
