Answer:
Sentence containing a participial phrase: <u>RISING EARLY</u>, Lucy was able to do all the pending chores.
Word modified by the phrase: Lucy
Explanation:
A participial phrase is a phrase consisting of a participle (whether present or past) and their modifiers, and that acts as adjective, that is, it describes or modifies nouns. There are two types of participles: the present participle, which ends in <em>-ing</em>, like <em>winning</em>, and the past participle which is formed from the past tense of a verb, and therefore they usually have the endings<em> -ed, -d, -t, -en, </em>or<em> -n</em>, such as <em>smiled, thought </em>and<em> swollen.</em>
What follows is a sentence containing a participial phrase:
<u><em>Rising early</em></u><em>, Lucy was able to do all the pending chores.</em>
In this sentence, <u><em>Rising early</em></u> is a participial phrase because it consists of a participle: <em>rising</em>, and an adverb which is the modifier of that participle: <em>early</em>, and it acts as an adjective, modifying and giving us information about <u><em>Lucy</em></u>, which is a noun, and also the subject of the sentence.
