In the rapidly evolving academic field of CALL （computer-assisted language leaming） in China, it is no longer a question of whether to take advantage of the technologies of computer and Internet in foreign language instruction, but of how to make effective use of them. By reviewing the literature of CALL in China and abroad, this article holds the view that in China where the educational resources are insufficient and unevenly distributed, the use of CALL should confirm and expand ESL/EFL theories to the utmost; the research of CALL should focus more on learning or learner, especially on learning strategy in CALL environment; to have a better understanding of the potential and functions of CALL in foreign language instruction, the research of CALL should cover all aspects of language learning.
