Worksheet designed to help students practice using the articles "a," "an," and "the" in sentences, illustrated with a student writing and a "Teachers Instruction" logo.

Let's solve this grammar exercise step by step. The task is to fill in the blanks with a, an, or the, depending on the context.

🔹 Rules Reminder:

- A / An: Used for non-specific singular countable nouns.
- Use a before consonant sounds.
- Use an before vowel sounds.
- The: Used for specific nouns, unique things, or when both speaker and listener know what is being referred to.
- No article (zero article): Used with plural or uncountable nouns in general terms, or with names of meals, countries, etc.

Now let’s go through each sentence:

---

1. I saw ___ cat chasing ___ mouse through ___ garden last night.

- "cat" – non-specific → a
- "mouse" – non-specific → a
- "garden" – non-specific (any garden) → a

✔ a cat chasing a mouse through a garden

---

2. Could you pass me ___ book on ___ table, please?

- "book" – non-specific (any book) → a
- "table" – specific (the one they're referring to) → the

✔ a book on the table

---

3. She bought ___ new car yesterday.

- "new car" – non-specific (one of many possible cars) → a

✔ a new car

---

4. There's ___ apple and ___ orange on ___ kitchen counter.

- "apple" – singular, non-specific → an (because "apple" starts with a vowel sound)
- "orange" – singular, non-specific → an
- "kitchen counter" – specific (implied: the one in their kitchen) → the

✔ an apple and an orange on the kitchen counter

---

5. Would you like ___ cup of tea or ___ coffee?

- "cup of tea" – non-specific → a
- "coffee" – uncountable noun; no article needed? Wait — but here it's contrasting with "a cup of tea", so we need to match structure.
- "coffee" is uncountable, so we use no article for general meaning.
- But in contrast to "a cup of tea", it's better to say a coffee informally (though technically incorrect), but in formal English, we'd say some coffee.
- However, in this context, it's likely expecting a coffee as informal usage.

But let’s stick to standard grammar:

- "a cup of tea" → a
- "coffee" → some or no article? But since the blank is for a/an/the, and “coffee” is uncountable, we don’t use a/an.

Wait — but the blank is there, so maybe they expect a?

Actually, "a coffee" is acceptable in British English (e.g., "I’d like a coffee") meaning "a cup of coffee".

So:
- "a cup of tea" → a
- "a coffee" → a

✔ a cup of tea or a coffee

(Note: This is common in informal English.)

6. He's going to ___ university next year to study physics.

- "university" – general, not specific → a
- Even though "university" is singular, it's not a particular one → a

✔ a university

---

7. ___ sun is shining brightly in ___ sky today.

- "sun" – unique object → the
- "sky" – general, but often used with the (e.g., "in the sky")

✔ The sun is shining brightly in the sky

---

8. I need to buy ___ new pair of shoes for ___ upcoming trip.

- "pair of shoes" – non-specific → a
- "upcoming trip" – specific (the one being discussed) → the

✔ a new pair of shoes for the upcoming trip

---

9. Have you seen ___ movie we talked about last week?

- "movie" – specific (the one mentioned earlier) → the

---

10. She's wearing ___ beautiful dress to ___ party tonight.
