English grammar worksheet focusing on using "a" and "an" correctly in sentences.

Let’s go through each sentence one by one. The rule is simple:
- Use “a” before words that start with a consonant sound.
- Use “an” before words that start with a vowel sound (a, e, i, o, u — but remember, it’s about the *sound*, not just the letter!).

We’ll check each word after “a / an” to see what sound it starts with.

---

1. beehive → starts with “b” → consonant sound → a
2. picture → starts with “p” → consonant sound → a
3. accident → starts with “a” → vowel sound → an
4. olive → starts with “o” → vowel sound → an
5. long → starts with “l” → consonant sound → a
6. annoying → wait! It says “arnery” — probably meant “annoying”? But as written: “arnery” starts with “a” → vowel sound → an
*(Note: “arnery” isn’t standard English — likely typo for “annoying”, which also starts with vowel sound → still “an”)*
7. oversight → starts with “o” → vowel sound → an
8. surprise → starts with “s” → consonant sound → a
9. adorable → starts with “a” → vowel sound → an
10. noise → starts with “n” → consonant sound → a
11. reminder → starts with “r” → consonant sound → a
12. tissue → starts with “t” → consonant sound → a
13. eagle → starts with “e” → vowel sound → an
14. strange → starts with “s” → consonant sound → a
15. innocent → starts with “i” → vowel sound → An (capitalized because it’s start of sentence)

Wait — let’s double-check #6: “arnery” — if it’s really “annoying”, same thing — both start with vowel sounds. So “an” is correct.

Also #15: “A / An innocent...” — since “innocent” starts with vowel sound, we use “An” — and since it’s the start of the sentence, it should be capitalized.

Now let’s list all answers clearly:

1. a
2. a
3. an
4. an
5. a
6. an
7. an
8. a
9. an
10. a
11. a
12. a
