The outbreak of Corona Virus Disease 2019 (henceforth COVID-19) has put restrictions on travel and educational exchange. In terms of Sino-Foreign Cooperative Institutions, this pandemic has imposed a strain on normal operation of education process, as foreign teachers hardly have the access to the mainland of China for prevention and control. Thus, these institutions have to rely on online teaching as the only way to maintain teaching work. However, some courses taught online are not effective and cannot fully replace traditional classroom teaching. Therefore, this study target at the largest Sino-Australian cooperative school in Zhejiang Province of China as the research object, and conduct a survey on English teaching delivered by foreign teachers via online and face-to-face methods. Specifically, listening and reading modules are taught online while speaking and writing ones are taught face-to-face. It is found that the combination of these ways performs better from feedback students provide and can almost reach the standard of traditional classroom teaching.
