The task-based teaching method has a long history and is an excellent teaching method tested by time. The integration of the task-based approach into college English teaching is an important path in line with students’ growth and learning trajectories. For example, teachers can stimulate students’ interest in learning, improve students’ ability to understand the language and apply it in life practice by designing tasks that are consistent with students’ learning background. The research shows that this teaching method can effectively improve students’ oral expression, written writing, and team cooperation. At the same time, it also points out the problems faced in the implementation process, such as task difficulty control, time management, etc., and puts forward corresponding improvement strategies and suggestions for these problems.
