My cat is too playful

My cat is very playful

1.My cat is very playful

To correct the sentences for subject-verb agreement, tense, and fragments, follow these guidelines:

1. My cat is very playful.
- Correction: Remove the pronoun "it" as it is unnecessary since "cat" is already the subject. Also, add the appropriate verb form "is" to match the singular subject "cat."

2. When he thought he could afford to pay his own school fees.
- Correction: This sentence seems to be a fragment and lacks a main verb. Adding a verb would make it a complete sentence.
- Example correction: He thought he could afford to pay his own school fees.

3. These children keep making noise.
- Correction: Change "This" to "These" to match the plural subject "children."
- Example correction: These children keep making noise.

4. These are great news indeed; I can't believe I made it!
- Correction: Change "news" to "pieces of news" or "pieces of information" since "news" is an uncountable noun. Also, capitalize the first letter of the sentence after the semicolon. Additionally, maintain consistency in the verb form - change "i" to "I" and "can't" to "can't".
- Example correction: These are great pieces of news indeed; I can't believe I made it!

Remember, subject-verb agreement involves using the correct verb form based on the subject's number (singular or plural), tense refers to the appropriate timeframe of the action being described, and a complete sentence contains both a subject and a verb, expressing a complete thought.
