error correction - ESL worksheet by keani75 - Free Printable

Let's go through each sentence, identify the grammar error, and provide the corrected version with an explanation.

---

1. He go to bed very early.

Error: Subject-verb agreement. "He" is third person singular, so the verb must be "goes."
Corrected: *He goes to bed very early.*

---

2. Does they live in Canada?

Error: Incorrect use of auxiliary verb. "Does" is used with third person singular, but "they" is plural. Use "Do" for plural subjects.
Corrected: *Do they live in Canada?*

---

3. I am usually cook dinner for my family.

Error: Incorrect verb form. "Am" and "cook" cannot be used together like this. "Usually" modifies the verb, so we need the base form after "am" — but here it should be a simple present tense: "I usually cook."
Corrected: *I usually cook dinner for my family.*

---

4. Are they have a meeting every week?

Error: Incorrect structure for questions. "Are" is not used with "have" in this way. We need to use "Do" as the auxiliary verb.
Corrected: *Do they have a meeting every week?*

---

5. She don't like tennis.

Error: Subject-verb agreement. "She" is third person singular, so use "doesn't" instead of "don't."
Corrected: *She doesn't like tennis.*

---

6. Does John has enough money?

Error: Auxiliary verb "Does" already indicates the question; the main verb must be in base form ("have").
Corrected: *Does John have enough money?*

---

7. He know the answer.

Error: Subject-verb agreement. "He" needs "knows."
Corrected: *He knows the answer.*

---

8. Robert playes baseball on the weekend.

Error: Spelling mistake. "Playes" should be "plays."
Corrected: *Robert plays baseball on the weekend.*

---

9. They has lots of free time.

Error: Subject-verb agreement. "They" is plural, so use "have."
Corrected: *They have lots of free time.*

---

10. Do they usually driving to work?

Error: Incorrect verb form. After "Do," the verb should be in base form, not "-ing."
Corrected: *Do they usually drive to work?*

---

11. Jenny is not work at a restaurant.

Error: Incorrect verb form. "Is not" + "work" is wrong. It should be "does not work" or "isn't working."
But since it’s a habitual action, better to use simple present.
Corrected: *Jenny does not work at a restaurant.*
*(Alternative: Jenny isn’t working at a restaurant – if referring to present moment)*

---

12. She worries too much about the exams.

Error: This sentence is actually correct. "Worries" is the correct third-person singular form of "worry." No correction needed.
✔ *She worries too much about the exams.*

---

13. My father wants to travels to Spain.

Error: After "to," we use the base form of the verb. "Travels" is incorrect.
Corrected: *My father wants to travel to Spain.*

---

14. Why you study English?

Error: Missing auxiliary verb. To form a question, we need "do" or "does."
Corrected: *Why do you study English?*

---

15. He doesn't drinks tea.

Error: After "doesn't," the verb must be in base form. "Drinks" is incorrect.
Corrected: *He doesn't drink tea.*
