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.
✔ *Explanation:* In the present simple tense, third-person singular subjects (like Jack) require the verb to end in "-s" or "-es".
---
2. My dog usually eat around five.
-
Mistake: "eat" should be "eats" because "dog" is a singular subject.
-
Corrected Sentence: My dog usually
eats around five.
✔ *Explanation:* Again, singular subject ("dog") needs a singular verb form — "eats".
---
3. John drive to work every day.
-
Mistake: "drive" should be "drives" for third-person singular subject.
-
Corrected Sentence: John
drives to work every day.
✔ *Explanation:* "John" is a singular person, so we use "drives" instead of "drive".
---
4. Monicas dog loves to go running with her.
-
Mistake: "Monicas" should be "Monica's" to show possession.
-
Corrected Sentence: Monica's dog loves to go running with her.
✔ *Explanation:* To show that the dog belongs to Monica, we need to add an apostrophe and an "s" → "Monica's".
---
5. Stan has a friend whos in the military.
-
Mistake: "whos" is missing an apostrophe; it should be "whose".
-
Corrected Sentence: Stan has a friend
whose is in the military.
✔ *Explanation:* "Whose" is a possessive pronoun meaning "belonging to whom". "Whos" is incorrect — it’s a common misspelling. The correct form is "whose".
---
✔ Final Answers:
1.
Jack runs outside to see his friend.
→ Circle: *run* → Correct:
runs
2.
My dog usually eats around five.
→ Circle: *eat* → Correct:
eats
3.
John drives to work every day.
→ Circle: *drive* → Correct:
drives
4.
Monica's dog loves to go running with her.
→ Circle: *Monicas* → Correct:
Monica's
5.
Stan has a friend whose is in the military.
→ Circle: *whos* → Correct:
whose
> Note: In sentence 5, if you want to make it even more natural, you might say:
> *"Stan has a friend who is in the military."*
> But since the original uses "whos", the correction is just adding the apostrophe →
whose.
