Subject and Object Pronouns worksheet with fill-in-the-blank and identification exercises.

Let's solve this grammar worksheet step by step. The task involves identifying subject and object pronouns, and then using appropriate pronouns to complete sentences.

A. Identify the underlined pronoun as a subject or object pronoun

We are given sentences with underlined pronouns (though in your text, they aren't visibly underlined — but we can infer based on context). Let's analyze each one.

1. They lived long before the invention of writing.
- "They" is the subject of the sentence (performing the action of living).
→ Subject pronoun

2. We still know something about them.
- "Them" receives the action ("know about"). It’s the object of the preposition "about".
→ Object pronoun

3. For many years scientists have studied this.
- There is no pronoun here. "This" is a demonstrative pronoun, but it's not a personal pronoun like *they*, *him*, etc.
→ No pronoun (or "this" is a demonstrative pronoun)

4. She found what might be the footprints of a small child.
- "She" is the subject performing the action "found".
→ Subject pronoun

5. The print clearly belonged to him.
- "Him" is the object of the preposition "to". It receives the action.
→ Object pronoun

6. It is considered a fossil.
- "It" is the subject of the sentence.
→ Subject pronoun

7. They are mostly skulls, bones, and teeth.
- "They" is the subject.
→ Subject pronoun

✔ Answers for Part A:

1. Subject
2. Object
3. No pronoun (or "this" is not a personal pronoun)
4. Subject
5. Object
6. Subject
7. Subject

> Note: If "this" were underlined, it would be a demonstrative pronoun, not a subject or object pronoun in the traditional sense. But since the instruction says “subject or object pronoun,” and “this” isn’t one of those, we note that it’s not applicable.

B. Fill in the blank with a pronoun that fits the sentence

Now we fill in the blanks with correct pronouns (subject or object), making sure they agree in number and person.

1. Cro-Magnons lived in modern Europe. Today, ________ are called modern humans.
- "Cro-Magnons" is plural. The pronoun must be plural and refer to them as the subject.
→ They

2. Scientists study the lives of these people. They want to learn more about ________.
- "These people" is the object of "about". We need an object pronoun.
→ them

3. A fossil can be different things. It is created when rocks form around ________.
- Rocks form around the remains of organisms. "It" refers to the fossil, so the rock forms around it.
→ it

4. A fossil is like a clue. ________ tells scientists a story.
- "A fossil" is the subject. We need a subject pronoun to replace it.
→ It

5. Cave artists did not sign their work. ________ lived long before writing was invented.
- Refers back to "cave artists" (plural). Need a subject pronoun.
→ They

6. We are always trying to learn more about the paintings. They continue to fascinate ________.
- "They" (the paintings) fascinate us (the people). "Us" is the object of "fascinate".
→ us

7. The path led up to the cliff. ________ ended at a narrow ledge.
- "The path" is singular. The pronoun should be singular and subject.
→ It

8. The three friends met one afternoon. ________ shared a love of adventure.

🔍 Summary of Key Concepts:

- Subject Pronouns: I, you, he, she, it, we, they → perform the action.
- Object Pronouns: me, you, him, her, it, us, them → receive the action.
- Some pronouns like *this, that, these, those* can be both subject or object depending on use, but they're not personal pronouns.
- Always check if the pronoun is the doer (subject) or receiver (object).
