Cách sử dụng
The expression "spring into action" means to start doing something quickly and energetically. It is often used when there is some kind of urgency or emergency situation that requires immediate action. For example, if there is a fire in a building, the firefighters would "spring into action" to put out the fire. It can also be used in less urgent situations, such as when someone suddenly decides to start working on a project they've been putting off for a long time.
