Explanation:
We are asked to identify the
prepositional phrase in each sentence. A prepositional phrase starts with a
preposition (like *over, on, without, beneath, by, for, in, at, in, of, for*) and ends with a
noun or pronoun (called the object of the preposition). It often tells *where*, *when*, or *how* something happens.
Let’s go through each sentence one by one:
1. *Can you jump over this rock?*
→ Preposition:
over
→ Object:
this rock
→ Phrase:
over this rock
2. *You can jump high on the moon.*
→ Preposition:
on
→ Object:
the moon
→ Phrase:
on the moon
3. *Without Earth’s gravity we are much lighter.*
→ Preposition:
Without
→ Object:
Earth’s gravity
→ Phrase:
Without Earth’s gravity
4. *We could stand beneath a full Earth.*
→ Preposition:
beneath
→ Object:
a full Earth
→ Phrase:
beneath a full Earth
5. *Can you read a book by earthlight?*
→ Preposition:
by
→ Object:
earthlight
→ Phrase:
by earthlight
6. *One moon day lasts for 28 Earth days.*
→ Preposition:
for
→ Object:
28 Earth days
→ Phrase:
for 28 Earth days
7. *That would be a long day in school!*
→ Preposition:
in
→ Object:
school
→ Phrase:
in school
Now the second part: Identify the prepositional phrase in each sentence (they already contain one).
8. *Scientists have gazed at the skies.*
→ Preposition:
at
→ Object:
the skies
→ Phrase:
at the skies
9. *Is there more life in the universe?*
→ Preposition:
in
→ Object:
the universe
→ Phrase:
in the universe
10. *One day astronauts may fly at the speed of light.*
→ There are two possible prepositional phrases here:
-
at the speed
-
of light
But note: *“the speed of light”* is a noun phrase where *“of light”* modifies *speed*. So the full prepositional phrase is
at the speed of light, because *at* is the main preposition, and its object is *the speed of light* (a noun phrase containing another prepositional phrase inside it). In elementary grammar, we usually treat the whole chunk after *at* as the object — so the phrase is
at the speed of light.
11. *They will find life in a distant galaxy.*
→ Preposition:
in
→ Object:
a distant galaxy
→ Phrase:
in a distant galaxy
12. *That would be a great discovery for the Earth.*
→ Preposition:
for
→ Object:
the Earth
→ Phrase:
for the Earth
Double-checking all:
- All start with a preposition.
- All end with a noun/noun phrase.
- No missing words.
Final Answer:
1. over this rock
2. on the moon
3. Without Earth’s gravity
4. beneath a full Earth
5. by earthlight
6. for 28 Earth days
7. in school
8. at the skies
9. in the universe
10. at the speed of light
11. in a distant galaxy
12. for the Earth
