Grammar. Collection of exercises. Exercise 2. Insert the article where necessary.

Explanation:

This exercise requires filling in the blanks with the appropriate articles ('a', 'an', or 'the'). The choice depends on whether the noun is singular and countable, whether it's specific or general, and whether it starts with a vowel or consonant sound.

Answers:

• 1. When is your birthday? — My birthday is (on) 1st May. (The first 'birthday' is general, the second refers to a specific birthday).
• 2. Do you remember your mother's birthday? — Yes, I do. 3. His uncle is generous and her aunt is very kind. (General reference to 'uncle' and 'aunt').
• 4. That man is very clever. His book is recognized by a lot of people. (General reference to 'man' and 'book').
• 5. They know our address. 6. Their son speaks English very well. 7. My cousin's dog is small. Its hair is curly. (Specific 'address', general 'son', 'dog', and 'hair').
• 8. Is this watch? — No, it isn't the watch, it's a pen. 9. This pen is good, and that pencil on your table, but I can see no paper. 10. I can see a chair, please. 11. Give me a dog and two cats. 13. I have a spoon in my soup plate, but I have no soup in it. 14. My friend says he is going to be a millionaire one day. 15. Would you like an orange? 16. Mr Smith is an artist. Mrs Smith is a poetess. She is not a singer.

Note: The word 'article' refers to 'a', 'an', and 'the'. The term 'birthday' can sometimes take 'the' if it's a specific, known birthday, but in this general context, it functions as a common noun. Similarly, 'hair' is often used without an article when referring to hair in general. The examples provided for numbers 12-16 are based on typical English usage for these phrases.
