Differences Between Past, Present, and Future Tenses

1. What is Tense?

• Past Tense: This is used for actions that already happened.
  • Example: I walked to school.
• Present Tense: This talks about actions that are happening now or happen regularly.
  • Example: I walk to school.
• Future Tense: This is for actions that will happen later.
  • Example: I will walk to school.

2. Matching Subjects and Verbs:

• The subject (who or what the sentence is about) and the verb (the action) need to match in number.
  • Example: He walks (one person) vs. They walk (more than one person).

3. Asking Questions:

• To make a question, you can switch the order of the subject and verb or use helper words.
  • Example: Did you walk? (past)
  • Do you walk? (present)
  • Will you walk? (future)

4. Making Sentences Negative:

• You can add 'not' or 'never' to make a sentence negative.
  • Example: I did not walk. (past)
  • I do not walk. (present)
  • I will not walk. (future)

5. Using Articles:

• Use 'a' or 'an' when you’re not talking about something specific.
  • Example: I saw a dog.
• Use 'the' when you’re talking about something specific.
  • Example: I saw the dog that barks.
