Grade 4 English worksheet focusing on the use of articles "a," "an," and "the" in sentences.

To solve the problem, we need to fill in the blanks with the appropriate articles: a, an, or the. Here's a step-by-step explanation for each sentence:

Rules for Articles:

1. The: Used before specific or unique nouns, proper nouns, or when referring to something already mentioned.
2. A/An: Used before non-specific or general nouns. "An" is used before words starting with a vowel sound (a, e, i, o, u), while "a" is used before words starting with a consonant sound.

Solutions:

1. The sun sets in the west.
- "The sun" refers to a specific and unique object.
- "The west" refers to a specific direction.

2. Anne is fond of listening to a song now.
- "A song" is a general noun, so "a" is used.

3. Mr. Roger works at a Computer software firm.
- "A Computer software firm" is a general noun, so "a" is used.

4. Etham and Kevin like to watch Comedy shows on TV.
- "Comedy shows" is a general noun, so no article is needed here (it's plural and general).

5. Akbar was a great king.
- "A great king" is a general noun, so "a" is used.

6. Anne is the best student of mathematics in the class.

7. Gold is a precious metal.
- "A precious metal" is a general noun, so "a" is used.

8. I am a school student.
- "A school student" is a general noun, so "a" is used.

9. I want a pear from that tree instead.
- "A pear" is a general noun, so "a" is used.

10. John met a boy in the Supermarket and asked him a question.
- "A boy" is a general noun, so "a" is used.
- "The Supermarket" refers to a specific place, so "the" is used.
- "A question" is a general noun, so "a" is used.

11. It's Friday. Many people in our neighbourhood have gone to the mosque.
- "Friday" is a proper noun (day of the week), so no article is needed.
- "The mosque" refers to a specific place, so "the" is used.

12. John borrowed a pen and an eraser from Anne.
- "A pen" is a general noun, so "a" is used.
- "An eraser" starts with a vowel sound, so "an" is used.

13. My cousins are coming over for an exciting evening of games.

- "An hour" starts with a vowel sound, so "an" is used.
