Grade 8 English worksheet focusing on word forms, specifically using the correct form of words in brackets to complete sentences about friends and personality traits.

Let's solve each sentence by using the correct form of the word in brackets. We'll look at the context and determine whether we need an adjective, noun, adverb, or other part of speech.

---

1. Vietnamese people are very warm and ____________________. (friend)
→ "Friend" is a noun; we need an adjective to describe people.
✔ friendly

2. La Hill is a ________________________ writer. (humor)
→ "Humor" is a noun; we need an adjective to describe the writer.
✔ humorous

3. I’m ________________________ sorry for coming late. (extreme)
→ "Extreme" is an adjective; we need an adverb to modify "sorry."
✔ extremely

4. I love the ____________ of the atmosphere in the countryside. (peaceful)
→ "Peaceful" is an adjective; we need a noun. The noun form is "peacefulness."
✔ peacefulness

5. Bao is very ________________________, kind and generous. (social)
→ "Social" is already an adjective; it fits here as a description of personality.
✔ social

6. Each of my friend has a ________________________ character. (difference)
→ "Difference" is a noun; we need an adjective to describe "character."
✔ different

7. We are good friends although each of us has a different ____________ (characteristic)
→ "Characteristic" is already a noun; we need the plural form since "each of us" implies multiple traits.
✔ characteristic (already correct — singular is okay because "a different characteristic" means one trait per person)

Wait: “Each of us has a different characteristic” — this is grammatically correct with singular. But if you want to emphasize multiple traits, it could be plural. However, the sentence says "a different," so it’s singular.
✔ characteristic

8. He spends most of his time doing charity work. He’s a ____________ man. (social)
→ "Social" as an adjective means "interested in social matters"; "social" can also mean "sociable," but here it refers to someone involved in society/community.
But "social" is not the best fit. Let's consider:
He does charity → he cares about society → socially active? But we need one word.
Actually, "social" isn't ideal. Wait — perhaps charitable? But that’s not from the root.
Wait — the word given is "social".
We use social to describe someone who is involved in social issues.
✔ social (as in "a socially conscious man" — but here just "social" might be acceptable).
But better: social can be used as an adjective meaning concerned with society.
So: ✔ social

Alternatively, maybe they expect sociable, but that’s not from "social" directly? No, "sociable" is derived from "social".

But the base word is "social", and the adjective form is social.

So: ✔ social

9. He has a sense of _______________ because he often tells jokes. (humorous)
→ "Humorous" is an adjective; we need a noun. The noun form is humor.
✔ humor

10. Nam makes friends very _______________ because he is very sociable. (ease)
→ "Ease" is a noun; we need an adverb to modify "makes friends".
The adverb form of "ease" is easily.
✔ easily

11. Hoa is very _________. She doesn’t talk to anybody in her class. (reservation)
→ "Reservation" is a noun; we need an adjective.
The adjective form is reserved.
✔ reserved

12. A(n) _________________ is a child who lost his parents. (orphanage)
→ "Orphanage" is a noun meaning a home for orphans.
But the sentence needs a noun meaning "a child without parents" — that's orphan.
So we need to change "orphanage" to orphan.
✔ orphan

13. They were very ____________ to survive a fire. (luck)
→ "Luck" is a noun; we need an adjective.
The adjective is lucky.
✔ lucky

14. Nga often helps poor and homeless people. She is ________ ____. (generosity)
→ "Generosity" is a noun; we need an adjective to describe "She is...".
The adjective form is generous.
So: ✔ generous

But there are two blanks?
" She is ________ ____." → probably a typo. Likely meant to be one blank.
But it shows two underscores. Maybe it wants very generous? But only one word is given.

Wait: "She is ________ ____." — perhaps it's expecting a generous person? But that’s not matching the bracket.

But the word is "generosity" → adjective = generous
So likely: ✔ generous (and the second blank may be a mistake, or perhaps it's "very generous"? But no word is given.)

Wait — maybe it's generous-hearted? But that’s not standard.

No — simplest answer: generous

But the sentence says "She is ________ ____." — two blanks?

Possibly a formatting error. Likely meant to be one blank: She is generous.

But let’s assume it's one blank.
✔ generous

If two blanks, maybe: very generous — but "very" isn't from "generosity".

So probably just generous

But the original says: "She is ________ ____." — maybe it's full of generosity? But that’s not logical.

No — the expected answer is likely generous

So: ✔ generous

15. _______________, her sister passed the driving test. (luck)
→ "Luck" is a noun; we need an adverb to start the sentence.
The adverb form is Luckily.
✔ Luckily

Explanation Summary:

- Adjectives are used to describe nouns (e.g., *friendly*, *humorous*).
- Adverbs modify verbs, adjectives, or other adverbs (e.g., *extremely*, *easily*, *luckily*).
- Nouns are used when the sentence needs a thing or concept (e.g., *peacefulness*, *humor*, *orphan*).
- Word forms must match the grammatical role in the sentence.
- Sometimes, we need to derive the correct part of speech from the base word (e.g., *reservations* → *reserved*).
