Adverb phrases and prepositional phrases are both commonly used as adjuncts,

and may often paraphrase each other in meaning:

I’m going to have to drive 

very carefully.

Even where records are available, they have to be interpreted 

with care.

Adjuncts may also be compared to adverbial clauses. In this grammar book,

adverbial clauses are treated as elements of the sentence structure, rather than as

adjuncts in the clause structure. However, the meanings of adverbial clauses are

often similar to the meanings of adjuncts:

She wrote to me 

when she arrived in Oxford.

(adverbial clause)

She wrote to me 

upon her arrival in Oxford.

(same meaning realised as prepositional phrase adjunct)
