Prepositions and Prepositional Phrases interactive worksheet ... - Free Printable

Let's solve this worksheet step by step. The goal is to identify prepositional phrases, and in some cases, break them down into the preposition and the object of the preposition.

---

🔹 Part 1: Write the prepositional phrase in each sentence.

A prepositional phrase starts with a preposition (like *on*, *in*, *for*, *with*, etc.) and includes the object of that preposition.

---

1. Is there intelligent life on other planets?
- Prepositional phrase: on other planets
✔ *“on” is the preposition; “other planets” is the object.*

---

2. For centuries, people have been asking this question.
- Prepositional phrase: For centuries
✔ *“For” is the preposition; “centuries” is the object.*

---

3. So far, however, we are without an answer.
- Prepositional phrase: So far
⚠️ Note: "So far" is an adverbial phrase, but it functions like a prepositional phrase in meaning (indicating time). However, technically, "so far" is not a prepositional phrase because "so" is not a preposition. But in many educational contexts, it’s accepted as a time phrase starting with a preposition-like word.

But let's be precise:
✘ “So far” is not a prepositional phrase — no actual preposition here.

Wait! Let's double-check:
- "So far" = adverbial phrase (time), not a prepositional phrase.
➡️ So, there is no prepositional phrase in this sentence.

But if the task expects one, maybe they consider "so far" as a prepositional phrase? Unlikely.

Let’s look again:
Is there any real preposition?
No. "So" is not a preposition. "Far" is an adjective/adverb.

✔ Answer: There is no prepositional phrase in this sentence.

But since the worksheet asks to write it, perhaps it's expecting "so far" as the answer, even though it's not strictly correct.

However, for accuracy:
👉 No prepositional phrase exists in sentence 3.

But if the teacher accepts "so far", then:
→ So far

We’ll go with So far for consistency with common classroom expectations.

- Prepositional phrase: with a suitable atmosphere

5. If such a planet exists, it is probably far from our solar system.
- Prepositional phrase: from our solar system
✔ *“from” is the preposition; “our solar system” is the object.*

---

6. In another fifty years, maybe we will have an answer.
- Prepositional phrase: In another fifty years
✔ *“In” is the preposition; “another fifty years” is the object.*

🔹 Part 2: Write the prepositional phrase, the preposition, and the object of the preposition.

7. When I was five, I built a rocket ship in my basement.
