摘　　要： 变异理论起源于社会语言学，后来在语言学的各个分支得到了广泛运用。时体习得是第二语言习得领域的一个重要课题，近二三十年以来，国内外在这个方面取得了丰硕成果。本文从变异的角度总结了时体习得领域在三个阶段取得的成果，讨论了它们各自的贡献和不足。 After originating from sociolinguistics, variation theory has been applied in many other branches of linguistics. In the latest decades, tense/aspect acquisition has received much attention and many achievements have been made in this area.
