Here's the corrected version of each sentence with explanations:
---
1. Tom doesn’t wants to clean his room today.
✔ Correction: Tom doesn’t want to clean his room today.
🔹 *Explanation:* After “doesn’t” (third person singular negative auxiliary), we use the base form of the verb — “want,” not “wants.”
---
2. Helen always is talking too much with her friends.
✔ Correction: Helen is always talking too much with her friends.
🔹 *Explanation:* Adverbs like “always” usually come after the first auxiliary verb (“is”) in continuous tenses, not before.
---
3. The boys play football in the yard yesterday.
✔ Correction: The boys played football in the yard yesterday.
🔹 *Explanation:* “Yesterday” indicates past simple tense. “Play” is present; it should be past tense “played.”
---
4. Who help you to do your homework every day?
✔ Correction: Who helps you to do your homework every day?
🔹 *Explanation:* “Who” as subject takes third person singular verb — “helps.” Also, “to do” is acceptable, but “with” is more natural: “help you with your homework.”
→ Even better: Who helps you with your homework every day?
---
5. Tom had helped me to make a kite three days ago.
✔ Correction: Tom helped me to make a kite three days ago.
🔹 *Explanation:* “Three days ago” refers to a specific time in the past — use simple past, not past perfect. Past perfect (“had helped”) is for actions before another past action.
---
6. Where did you lived in 2004?
✔ Correction: Where did you live in 2004?
🔹 *Explanation:* After “did,” use the base form of the verb — “live,” not “lived.”
---
7. The tasks was very difficult in the previous test.
✔ Correction: The tasks were very difficult in the previous test.
🔹 *Explanation:* “Tasks” is plural → verb must be plural “were,” not “was.”
---
8. Look! Bill catches a funny little pig in the yard.
✔ Correction: Look! Bill is catching a funny little pig in the yard.
🔹 *Explanation:* “Look!” suggests an action happening right now → use present continuous, not simple present.
---
9. Your answer is very interested. I like it a lot.
✔ Correction: Your answer is very interesting. I like it a lot.
🔹 *Explanation:* “Interested” describes how a person feels. “Interesting” describes something that causes interest — here, the *answer* is interesting.
---
10. I haven’t never visited this country.
✔ Correction: I have never visited this country.
🔹 *Explanation:* Double negative error. “Haven’t never” = incorrect. Use either “haven’t visited” or “never visited.” Best: “I have never visited…”
---
11. Sam stood at the bust stop when I see him yesterday.
✔ Correction: Sam stood at the bus stop when I saw him yesterday.
🔹 *Explanation:* Typo: “bust” → “bus.” Also, “see” should be past tense “saw” to match “yesterday.”
---
12. Liz will do her homework by three o’clock tomorrow.
✔ Correction: Liz will have done her homework by three o’clock tomorrow.
🔹 *Explanation:* “By three o’clock tomorrow” implies completion before that time → use future perfect tense: “will have done.”
---
13. Andrew already buy milk when I saw him yesterday.
✔ Correction: Andrew had already bought milk when I saw him yesterday.
🔹 *Explanation:* “Already” + past action before another past action → use past perfect: “had bought.”
---
14. They just watched this awful film.
✔ Correction: They have just watched this awful film.
🔹 *Explanation:* “Just” with past simple is incorrect in this context. When “just” means “a moment ago,” use present perfect: “have just watched.”
---
15. Mary always fall down because she was so absent-minded.
✔ Correction: Mary always falls down because she is so absent-minded.
🔹 *Explanation:* “Always” indicates habitual action → use simple present tense. Also, “was” should be “is” to match the present habit.
