The main difference between Simple Past and Simple Present is the timeframe they refer to. Simple Present is used to talk about actions that are happening now or regularly occur, while Simple Past is used to talk about actions that were completed in the past. In Simple Present, the verb is in its base form or with an -s ending for third person singular subjects, while in Simple Past, regular verbs end in -ed and irregular verbs have specific past tense forms. **

The Simple Past tense is used to talk about actions that were completed in the past, while the Simple Present tense is used to talk about actions that are happening in the present. To distinguish between the two, look for keywords such as "yesterday," "last week," or specific times that indicate the action happened in the past, which would indicate the use of Simple Past. On the other hand, if the sentence includes words like "now," "currently," or general time markers, it is likely using Simple Present. Additionally, pay attention to the verb forms - Simple Past verbs often end in "-ed" or have irregular forms, while Simple Present verbs typically end in "-s" in the third person singular form. **

To differentiate between Simple Past and Simple Present, you need to look at the timing of the action. Simple Past is used to talk about actions that happened in the past and are completed. It is formed by adding -ed to regular verbs or using the past form of irregular verbs. On the other hand, Simple Present is used to talk about actions that are happening now, habitual actions, general truths, or scheduled future events. It is formed by using the base form of the verb. By paying attention to the timing of the action and the form of the verb, you can easily differentiate between Simple Past and Simple Present. **
