When correcting sentences in English, it is important to ensure proper verb agreement, subject-verb clarity, and correct sentence structure. Below is a detailed explanation of the mistakes in each sentence and their corrections:
1. This my daughter.
- Mistake: The verb "is" is missing in the sentence. In English, a linking verb is required to connect the subject ("This") to the complement ("my daughter").
- Correct Sentence: This is my daughter.
2. These is my children.
- Mistake: The verb "is" does not agree with the plural subject "These." The correct verb in this case is "are."
- Correct Sentence: These are my children.
3. Kate my niece.
- Mistake: The linking verb "is" is missing, making the sentence incomplete.
- Correct Sentence: Kate is my niece.
4. Their family very large.
- Mistake: The verb "is" is missing. A verb is necessary to complete the sentence.
- Correct Sentence: Their family is very large.
5. Their twins 5 years old.
- Mistake: The verb "are" is missing, as "twins" is a plural subject.
- Correct Sentence: Their twins are 5 years old.
6. I 18 years old.
- Mistake: The verb "am" is missing. In English, the verb "to be" is required in sentences about age.
- Correct Sentence: I am 18 years old.
7. Those families very happy.
- Mistake: The verb "are" is missing. The subject "Those families" is plural, so the correct verb is "are."
- Correct Sentence: Those families are very happy.
8. They am William’s brothers.
- Mistake: The verb "am" is incorrect for the plural subject "They." The correct verb for the plural subject is "are."
- Correct Sentence: They are William’s brothers.
9. Harry Sam’s cousin.
- Mistake: The verb "is" is missing, making the sentence incomplete.
- Correct Sentence: Harry is Sam’s cousin.
10. Sally and Beth is sisters.
- Mistake: The verb "is" does not agree with the plural subject "Sally and Beth." For plural subjects, the correct verb is "are."
- Correct Sentence: Sally and Beth are sisters.
Summary:
In all the sentences above, the primary issue is the omission or incorrect use of the verb "to be" in its various forms (is, are, am). Correcting these errors ensures proper subject-verb agreement and completes the sentences grammatically.
