Example sentences demonstrating the "This is..." structure in grammar.

The image you've uploaded presents a grammar exercise focused on identifying the subject, verb, and object in simple English sentences. It's labeled "STYLE 1" and includes three example sentences:

1. This is a ball.
2. This is a tree.
3. This is a bird.

Each sentence is broken down into three columns: SUBJECT, VERB, and OBJECT, with guiding questions:
- Subject: Who? / What?
- Verb: What? (action or state of being)
- Object: What? / Where? / When?

---

Let's analyze each sentence:

#### 1. This is a ball.
- Subject: *This* → answers "What?" (It refers to something unspecified, but it's the subject).
- Verb: *is* → a form of the verb "to be", indicating a state of being.
- Object: *a ball* → answers "What?" (the thing being described).

✔ So:
- Subject: This
- Verb: is
- Object: a ball

#### 2. This is a tree.
- Subject: *This*
- Verb: *is*
- Object: *a tree*

✔ Same structure as above.

#### 3. This is a bird.
- Subject: *This*
- Verb: *is*
- Object: *a bird*

✔ Again, same pattern.

Summary of the Pattern:

All three sentences follow the "This is X" structure, which is a common way to introduce or identify something.

| Sentence | Subject | Verb | Object |
|----------------------|---------|------|------------|
| This is a ball. | This | is | a ball |
| This is a tree. | This | is | a tree |
| This is a bird. | This | is | a bird |

Key Grammar Concept:

This is an example of a simple declarative sentence using the copula verb "to be" ("is"). In such sentences:
- The subject is what we're talking about.
- The verb ("is") links the subject to the object.
- The object describes or identifies the subject.

So, these are subject-copula-complement (SVC) structures, not subject-verb-object (SVO) in the action sense — because "is" is a linking verb, not an action verb.

---

Final Answer:

The solution is already correctly filled out in the image. Each sentence has:
- Subject: *This*
- Verb: *is*
- Object: *a ball*, *a tree*, or *a bird*

These are all examples of identifying things using the "This is..." construction.
