Final answer:
Prepositional phrases provide key information in sentences. For example, 'on Friday' in the sentence 'We went to the bowling alley on Friday' is a prepositional phrase indicating time. Similarly, 'from Albania' indicates origin in 'The ambassadors from Albania arrived.'
Step-by-step explanation:
When analyzing sentences for grammatical components, one must identify various elements such as nouns, adjectives, verbs, adverbs, independent and dependent clauses, and different types of phrases. Prepositional phrases are particularly important to look for since they often provide information about time, location, or relationship between different parts of the sentence. For instance, in the sentence 'We went to the bowling alley on Friday,' the phrase 'on Friday' is a prepositional phrase indicating when we went to the bowling alley. Similarly, in 'Mr. Billingsworth laughed at the antics of the class clown,' the phrase 'at the antics of the class clown' is a prepositional phrase that tells us what Mr. Billingsworth laughed at. Likewise, 'The ambassadors from Albania arrived,' includes the prepositional phrase 'from Albania,' which identifies the origin of the ambassadors.
Here are some sentences with prepositional phrases:
I left my book on the desk.
The dog ran through the park.
We sat under the shade of a tree.
