I want to apply for a job as a junior high school English teacher. What topics should I choose to teach on a trial basis?

I am in charge of recruiting teachers in our school, and I myself graduated with an English major. Generally, what we value most is not the content of the lecture. The key is to focus on a certain point and explain it thoroughly. Be organized and give examples. You might as well speak a sentence and tell the lexicon, syntax and even allusions contained in the sentence. That's enough
