Identify declarative sentences in this English grammar worksheet.

Let's solve this step by step.

We are asked to determine whether each sentence is declarative or not. A declarative sentence makes a statement and ends with a period (.), providing information or expressing an opinion.

Here’s how we analyze each sentence:

---

1. My new car is black.
→ This is a statement giving information.
✔ YES

2. How old are you?
→ This is a question (interrogative sentence).
✘ NO

3. Mark brushes his teeth thrice a day.
→ This is a statement about Mark’s habit.
✔ YES

4. This is the way to the mountain.
→ This is a declarative statement.
✔ YES

5. Wow! That car is so expensive!
→ Although it starts with an exclamation, the second part is a statement. However, the whole sentence expresses strong emotion and is exclamatory in tone. It's an exclamatory sentence, not purely declarative.
✘ NO

6. She is very interested in sports.
→ This is a clear statement of fact/opinion.
✔ YES

7. Where is the brown envelope?
→ This is a question (interrogative).
✘ NO

8. I really like to buy this toy.
→ This is a statement expressing a preference.
✔ YES

9. I never entered to that room.
→ This is a statement, but note: "entered to" is grammatically incorrect. The correct form would be "entered that room." However, even with the error, it's still a declarative sentence in intent. We assess based on structure, not grammar.
✔ YES (even though it has a grammatical error)

10. The earth is belong to the Solar System.
→ This sentence has a grammatical error: "is belong" should be "belongs" or "belongs to." But again, it's attempting to make a declarative statement. Despite the error, the intended function is declarative.
✔ YES (though grammatically incorrect, it's still a declarative sentence)

1. YES
2. NO
3. YES
4. YES
5. NO
6. YES
7. NO
8. YES
9. YES
10. YES

> ✔ Note: Sentences 9 and 10 have grammatical errors, but they are still declarative in type because they attempt to make a statement. The task is about sentence type, not correctness.
