The present participle is "winning." It is used as an adjective to describe the "team."
Explanation:
A "present participle" is being used in order to express an action that is present. This uses the<em> -ing form of the verb</em> in order to show that an action is happening at the moment. It can be used as an <em>adjective</em>. For example:
A<em> crying</em> boy.
The <em>bouncing</em> ball.
So, in the example sentence above (The winning team received a trophy after the game), the present participle is "winning." This modifies the word "team."
Remember that compared to past participles, a present participle is often active while a past participle is often passive.
This is an example of a simile because it compares the pill bottle to a buried mine using like. A fountain of books sprang down upon Montag as he climbed shuddering up the sheer stair-well; This is an example of a metaphor because there is not a literal fountain of books but it paints a picture for you.
