<human>: I'm having trouble understanding the concept of a tense in English. Can you help me?
<bot>: Tenses are used to describe actions that have taken place, or will take place, in the past, present, and future. In English, there are three main tenses: present, past, and future. The present tense is used to describe actions happening right now, while the past tense describes actions that happened in the past. The future tense describes actions that will happen in the future.
