### Definitions, Examples, Techniques, and Tips

#### Definitions:
- **Tense Usage**: Refers to the verb form that expresses when an action takes place—past, present, or future.
- **Present Tense**: Describes actions happening now or regularly (e.g., *She runs every day*).
- **Past Tense**: Describes actions that happened before (e.g., *He walked to school*).
- **Future Tense**: Describes actions that will happen (e.g., *They will go to the park*).

- **Subject-Verb Agreement**: Ensures that the subject of a sentence agrees with the verb in number (singular or plural).
- Singular subjects require singular verbs (e.g., *The dog barks*).
- Plural subjects require plural verbs (e.g., *The dogs bark*).

- **Sentence Structure**: Involves the organization of words in a sentence. Correct sentence structure ensures that the sentence makes sense and is grammatically accurate.
- **Run-on sentences**: Sentences that are improperly joined without appropriate punctuation (e.g., *I love to read I have many books*).
- **Sentence fragments**: Incomplete sentences that lack a subject or verb (e.g., *Running every day*).

- **Modals and Verb Forms**: Modals (can, must, may, should, etc.) are auxiliary verbs used to express necessity, ability, permission, and possibility. Using the correct modal and verb form in a sentence is essential to convey the correct meaning.

#### Examples:
- **Tense Usage**:
- Incorrect: *I have eaten dinner yesterday.* (Mixing present perfect with a specific time reference)
- Correct: *I ate dinner yesterday.*

- **Subject-Verb Agreement**:
- Incorrect: *The boy walk to school*.
- Correct: *The boy walks to school*.

- **Sentence Structure**:
- Incorrect: *She went to the store she forgot her wallet*.
- Correct: *She went to the store, but she forgot her wallet*.

- **Modals and Verb Forms**:
- Incorrect: *She can to sing well*.
- Correct: *She can sing well*.

#### Quick Learning Tips:
- **Tense Usage**: Pay attention to the time when the action happens. Match the verb tense with the time reference.
- **Subject-Verb Agreement**: Remember that singular subjects require singular verbs and plural subjects require plural verbs.
- **Sentence Structure**: Ensure every sentence has a subject and a verb. Avoid run-on sentences and fragments by using punctuation properly.
- **Modals**: Modals do not change form based on the subject (e.g., *I can*, *she can*).
