In this article, we will provide a comprehensive summary of the tenses used in English grammar, focusing on the tenses commonly taught in elementary school.Present Simple Tense。
The present simple tense is used to describe actions that are habitual, general truths, or facts. It is formed by using the base form of the verb. For example, "She plays the piano" or "The sun rises in the east."Present Continuous Tense。
The present continuous tense is used to describe actions that are happening at the moment of speaking or actions that are ongoing. It is formed by using the present tense of the verb "to be" (am, is, are) and the present participle of the main verb.
