Most sentences in English begin with the subject, move to the verb, and continue to the object, with modifiers tucked in along the way or put at the end. For the most part, such sentences are fine. Put too many of them in a row, however, and they become monotonous.

Adverbial modifiers are easily movable when they modify verbs; they can often be inserted ahead of the subject. Such modifiers might be single words, phrases, or clauses.

Like most adverbs, eventually does not need to appear close to the verb it modifies (began).

The adverb clause, which modifies the verb flew, is as clear at the beginning of the sentence as it is at the end.

Adjectives and participial phrases can frequently be moved to the beginning of a sentence without loss of clarity.

tip: When beginning a sentence with an adjective or a participial phrase, make sure that the subject of the sentence names the person or thing described in the introductory phrase. If it doesn’t, the phrase will dangle. (See S3-e.)
