My proposal
For classmates doing English 900, I have a proposal. When done reading following the official audio, why not give an impromptu speech. All the sentences in one lesson are the basic patterns describing a particular topic in daily life, however, taking out of context. How about putting those back into the context. Just design a scenario to use as much as possible the basic patterns in a freewheeling speech. One can also change the tone, the pitch, or add any variations that are closer to a live scene.
