For example:
1 Use your imagination to dub the movie.
Have a dialogue on a topic.
Let each student write the name or verb of an object in groups first, then draw lots or choose a member from other groups to describe it, and then guess which group will get extra points, so as to arouse enthusiasm and enliven the atmosphere.
4 or play English SMS games, plus body language, which is very funny.
In short: learning and playing go hand in hand, which will make you interested.
