To identify the prepositions and subjects in the given sentences, we can follow a few steps:

1) Understand what a preposition is: A preposition is a word that shows the relationship between a noun/pronoun (the object of the preposition) and another word in the sentence.

2) Identify the prepositions: Look for words that indicate location, direction, time, or introduce phrases. Common prepositions include "to," "at," "over," "down," "through," etc.

3) Identify the subjects: The subject is the noun or pronoun that performs the main action of the sentence or is being described.

Let's analyze each sentence:

1) The puppy came to our tent and slept at the foot of my sleeping bag.
- Prepositions: "to," "at," "of"
- Subjects: "puppy," "tent," "foot," "bag"

2) A skywriter flew over the field during the game.
- Prepositions: "over," "during"
- Subjects: "skywriter," "field," "game"

3) The city was without power for several hours.
- Prepositions: "without," "for"
- Subjects: "city," "power," "hours"

4) The cross-country team ran down the avenue and through the park.
- Prepositions: "down," "through"
- Subjects: "team," "avenue," "park"

Remember that some words can function as both prepositions and other parts of speech (e.g., "to" can also be an infinitive marker). However, in these sentences, the identified words are prepositions based on their usage.
