Solution to the "Practicing Preposition Worksheet"

We are asked to underline the prepositional phrase in each sentence. A prepositional phrase consists of a preposition and its object, and it modifies a noun, verb, or adjective by showing location, time, direction, or other relationships.

Let’s go through each sentence one by one:

---

#### 1. We walked up the stairs.
- Prepositional phrase: *up the stairs*
- Preposition: *up*
- Object: *stairs*
- This tells us the direction of walking.
✔ Answer: *up the stairs*

---

#### 2. My mom took a walk around the block.
- Prepositional phrase: *around the block*
- Preposition: *around*
- Object: *block*
- Tells where the walk was taken.
✔ Answer: *around the block*

---

#### 3. I looked under my bed.
- Prepositional phrase: *under my bed*
- Preposition: *under*
- Object: *bed* (note: "my" is a possessive adjective modifying "bed", not part of the prepositional phrase)
✔ Answer: *under my bed*

---

#### 4. The girl looked behind the door for her friend.
- There are two prepositional phrases here:
- *behind the door* → preposition: *behind*, object: *door*
- *for her friend* → preposition: *for*, object: *friend*
- Both modify the verb "looked".
✔ Answers: *behind the door* and *for her friend*

> Note: Since the instruction says “underline the prepositional phrase” (singular), but there are two, both should be identified. In some cases, only one might be expected, but both are valid.

---

#### 5. Don’t leave without your coat.
- Prepositional phrase: *without your coat*
- Preposition: *without*
- Object: *coat* ("your" is possessive modifier)
✔ Answer: *without your coat*

---

#### 6. During lunch we had a basketball tournament.
- Prepositional phrase: *During lunch*
- Preposition: *during*
- Object: *lunch*
- Tells when the tournament happened.
✔ Answer: *During lunch*

---

#### 7. The car traveled at a high speed.
- Prepositional phrase: *at a high speed*
- Preposition: *at*
- Object: *speed* ("a high" modifies "speed")
✔ Answer: *at a high speed*

---

#### 8. For a fraction of the cost you can buy a watermelon.
- Prepositional phrase: *For a fraction of the cost*
- Preposition: *for*
- Object: *fraction* (the rest — "of the cost" — is another prepositional phrase inside this one!)
- So, this is actually a compound prepositional phrase: *for a fraction of the cost*
- *for a fraction* → prepositional phrase
- *of the cost* → another prepositional phrase modifying "fraction"
✔ Answer: *For a fraction of the cost*

> This entire phrase functions as an adverbial phrase indicating price/condition.

---

#### 9. The boy tried to finish the race at any cost.
- Prepositional phrase: *at any cost*
- Preposition: *at*
- Object: *cost* ("any" is an adjective modifying "cost")
- Idiomatic expression meaning “no matter what”
✔ Answer: *at any cost*

---

✔ Final Answers (Underlined Phrases):

1. up the stairs
2. around the block
3. under my bed
4. behind the door, for her friend
5. without your coat
6. During lunch
7. at a high speed

🔍 Explanation Summary:

- A prepositional phrase starts with a preposition and ends with its object (a noun or pronoun).
- It often tells where, when, how, or why something happens.
- Some sentences have more than one prepositional phrase.
- Words like *my*, *your*, *a*, *high*, etc., are modifiers and not part of the prepositional phrase unless they're objects themselves.
