- Seagulls soared over the water, searching for food–adjectival phrase.
<u>Explanation</u><em>:</em>
<em>- The sign cautioned swimmers to stay within the designated swimming area:</em>
In this sentence, the word "within" acts as an adverbial phrase telling us where the swimmers were asked to stay. And the words "stay within the designated swimming area" is a prepositional phrase since it uses the preposition "within".
<em>- The lifeguards on the beach watched the swimmers carefully</em>:
Remember, adjectives are known for ending with 'ly', and the word "carefully" modifies the sentence, telling us how the lifeguards watched the swimmers.
<em>- Children and their parents built sandcastles with tall towers:</em>
This is the case because the adjective "tall" is used in the sentence to modify the word "tower", in a sense telling us the type of towers built.
<em>- Seagulls soared over the water, searching for food:</em>
The adjective "searching" is used to modify the entire sentence telling us what the Seagulls soared the waters for.
The Gettysburg Speech is perhaps the most important speech in US history. This speech was delivered by Lincoln in less than two minutes, at the end of the American civil war. That's because the message he wanted to give was fast, clear and didn't need a lot of arguments, because it was evident that it was true.
Lincoln inspired by the principles of equality defended in the Declaration of Independence of the country, declared the end of the war based on the concept that the country was born to be a country of free people and owners of their own lives, the end of the war allowed freedom be offered to everyone, as the founding fathers wanted and fought for it. Thus, Lincoln established that the end of the war would bring a nation united in recovery and truly free.
