No one likes tests, but everyone likes competitions. You probably wonder how much students learned from your lesson. Test their knowledge by leaving ten minutes at the end or at the beginning of class for a competition (bring prizes). Test their knowledge of the passage by having two teams compete for a prize by answering questions on what you have been teaching.
These kinds of tests might help your students remember what you have taught them and motivate them to listen, but tests also tell you, the teacher, whether or not your students are learning what you are attempting to teach.
