Step-by-step solution for: Correcting mistakes worksheet
Here is the corrected version of each sentence, along with explanations for the mistakes and how they were fixed:
---
- Mistake: Subject-verb agreement issue. "My friends and I" is a plural subject, so the verb should be "are."
- Correction:
My friends and I are good at surfing.
---
- Mistake: Incorrect use of "does" with the pronoun "you." "You" requires "do" instead of "does."
- Correction:
Where do you come from?
---
- Mistake: Tense error. The sentence is in the past tense, so "meet" should be "met."
- Correction:
Yesterday I met Helen at the library.
---
- Mistake: Incorrect preposition. "Since" is used with a specific point in time, not a duration. Use "for" with durations.
- Correction:
We have been friends for three years.
---
- Mistake: Incorrect auxiliary verb. In British English, "Have you..." is correct, but in American English, it should be "Do you have...?"
- Correction (American English):
Do you have a brother or sister?
---
- Mistake: Word order issue. Adverbs like "usually" should typically come after the main verb.
- Correction:
I usually read before I go to bed.
---
- Mistake: Incorrect verb form. After "didn't," the verb should be in the base form ("go").
- Correction:
Patrick didn't go on a school trip.
---
- Mistake: Incorrect comparative form. "As...as" requires the base form of the adjective ("tall").
- Correction:
Are you as tall as your mother?
---
- Mistake: Subject-verb agreement. "Greg and Tom" is a plural subject, so the verb should be "do."
- Correction:
Do Greg and Tom like fishing?
---
- Mistake: Punctuation error. This is a statement, not a question, so it should end with a period.
- Correction:
Simon can't play the recorder.
---
- Mistake: Incorrect infinitive form. "Must" is followed by the base form of the verb ("be").
- Correction:
A teacher must be a patient person.
---
- Mistake: Subject-verb agreement. "These" is plural, so the verb should be "are."
- Correction:
These are Larry's favorite toy cars.
---
- Mistake: Spelling error. "Then" should be "than."
- Correction:
A dog is cleverer than a hamster.
---
- Mistake: Verb form error. "Is" should be "isn't" to match the negative meaning.
- Correction:
My boss is never late for work.
---
- Mistake: Spelling error. "Bussines" should be "business."
- Correction:
Mr. Davis has been away on business.
---
- Mistake: Incorrect comparative form. "Goodder" should be "better."
- Correction:
Sue looks much better than yesterday.
---
- Mistake: Possessive form error. "Mothers" should be "mother's."
- Correction:
This is my mother's handbag.
---
- Mistake: Tense error. The sentence implies a completed action in the past, so "lived" should be "have lived."
- Correction:
The Clarks have lived next door for six weeks.
---
- Mistake: Incorrect use of "some." In negative sentences, "any" is more appropriate.
- Correction:
There isn't any honey left.
---
- Mistake: Subject-verb agreement. "Lessons" is plural, so the verb should be "start."
- Correction:
Lessons start at 9 in the morning.
---
- Mistake: Tense error. "Last weekend" indicates the past, so the sentence should be in the past tense.
- Correction:
We went shopping last weekend.
---
- Mistake: Pronoun case error. "He" should be "him" when used as the object of the preposition "at."
- Correction:
What a cute puppy! Look at him.
---
- Mistake: Incorrect future tense in the conditional clause. Use "If I have time..."
- Correction:
If I have time, I'll tidy up my room.
---
- Mistake: Spelling error. "Willn't" should be "won't."
- Correction:
I think people won't use cars in the future.
---
- Mistake: Tense error. The exclamation "Look!" suggests an ongoing action, so "paints" should be "is painting."
- Correction:
Look! Mike is painting the fence.
---
- Mistake: Subject-verb agreement. "There" is singular, so the verb should be "is."
- Correction:
Is there a river in your town?
---
- Mistake: Incorrect noun form. "Photos" should be "photographs."
- Correction:
My cousin loves taking photographs.
---
- Mistake: Subject-verb agreement. "Was" should be "were."

Where were you last night at 10?
---
- Mistake: Incorrect comparative structure. Use "prefers...to..." instead of "than."
- Correction:
Carol prefers reading to watching TV.
---
- Mistake: Incorrect word order. The auxiliary verb "did" should come after the subject.
- Correction:
Who broke the kitchen window?
---
- Mistake: Pronoun case error. "She" should be "her."
- Correction:
We cannot wait for her any more time.
---
- Mistake: Incorrect tag question. The tag should agree with the subject and verb in the main clause.
- Correction:
Your dad is a doctor, isn't he?
