7 Find and correct a mistake in each sentence.

Solution:

• The task is to identify and correct grammatical errors in six given sentences. This involves understanding English grammar rules related to subject-verb agreement, verb forms, and sentence structure.

Corrected Sentences:

• 1. They are not football players. (Mistake: 'isn't' is used with a plural subject 'They'. Corrected to 'are not' or 'aren't').
• 2. Are they Russian? (Mistake: The sentence is a question, so the subject 'they' should follow the auxiliary verb 'are'. Corrected to 'Are they Russian?').
• 3. We aren't into sport. (Mistake: 'arent' is missing an apostrophe. Corrected to 'aren't').
• 4. Are you from Moscow? Yes, I am. (Mistake: 'I'm' is a contraction of 'I am'. While grammatically acceptable in informal contexts, a more complete and often preferred answer in exercises is 'I am'. Alternatively, 'Yes, I'm' is also correct depending on the expected formality. Given the other corrections, assuming a more formal correction).
• 5. They are not music fans. (Mistake: 'not are' is incorrect word order and missing auxiliary verb. Corrected to 'are not' or 'aren't').
• 6. He's Egyptian. He is from Cairo. (Mistake: The second clause is missing a subject. Corrected to 'He is' or 'He's').
