Grammar Worksheet with Sentences to Correct

Let's go through each sentence one by one, identify the grammatical mistake, and then provide the corrected version.

---

1. Jack run outside to see his friend.

- Mistake: "run" should be "runs" because the subject "Jack" is singular and the sentence is in the present tense.
- Corrected sentence: *Jack runs outside to see his friend.*

✔ Correction: Change run → runs

2. My dog usually eat around five.

- Mistake: "eat" should be "eats" because the subject "my dog" is singular.
- Corrected sentence: *My dog usually eats around five.*

✔ Correction: Change eat → eats

3. John drive to work every day.

- Mistake: "drive" should be "drives" because "John" is a singular subject.
- Corrected sentence: *John drives to work every day.*

✔ Correction: Change drive → drives

4. Monicas dog loves to go running with her.

- Mistake: "Monicas" is missing an apostrophe to show possession. It should be "Monica's" to indicate that the dog belongs to Monica.
- Corrected sentence: *Monica's dog loves to go running with her.*

✔ Correction: Add apostrophe → Monica's

5. Stan has a friend whos in the military.

- Mistake: "whos" is missing an apostrophe. It should be "whose" (possessive pronoun), not "who's" (which means "who is").
- However, in this context, it's "whose", meaning "belonging to whom", so it’s correct as whose, not who's.
- Corrected sentence: *Stan has a friend whose in the military.* → Wait! There's a small error here too: “whose” needs to be followed by a noun or verb. But the sentence says “whose in the military” — this is incorrect.

Actually, the full phrase should be:
👉 *"Stan has a friend whose [friend] is in the military."*
But the original says: *"Stan has a friend whos in the military."*

So the mistake is:
- "whos" → should be "whose" (possessive)
- But "whose in the military" is incomplete. The correct form is: "whose friend is in the military" or "whose brother is in the military", etc.

But since the sentence is likely meant to say something like:
> "Stan has a friend whose [someone] is in the military."

However, if we assume the intended meaning is:
> "Stan has a friend who is in the military,"

Then the word "whos" is actually "who's", meaning "who is", not "whose".

Wait — let's clarify:

- "Whose" = possessive (e.g., "The book whose cover is red")
- "Who's" = contraction of "who is" or "who has"

In this case:
> "Stan has a friend who is in the military."

So the sentence should use "who's", not "whose".

But the original says: "whos" — which is a misspelling of "who's".

Therefore:
- The mistake is "whos" → should be "who's"
- But even then, the sentence would be: *"Stan has a friend who's in the military."* — which is correct.

✔ Correction: Change whos → who's

But note: "who's" is a contraction of "who is", so the sentence becomes:
> "Stan has a friend who is in the military."

This is grammatically correct.

So final correction:
✘ whos → ✔ who's
