When writing a sentence, it is important to think about when the action in your statement occurred. You should keep the tense uniform throughout the sentence when discussing things that happened at the same time. When referring to separate events, the tenses might differ, but it is important to recognize the difference. Below are some examples of tense agreement and disagreement.
