Explanation:
Words in simple present actually show action that take place regularly and those that are happening right now. The person (whether first person, second person or third person) determines the formation of the tense whether -s or -es will be added to the verb root word or not.
Prepositions are used in sentences before nouns, pronouns or noun phrases. They are used in order to time, place, direction, introduce an object or even show spatial relationship.
In the above sentences, the prepositions are used to show the time something occurs.
