This document provides information on the use of prepositions of time in English, including "since", "from", "until", and "for". It explains that "for" indicates a period of time, such as "She's been sleeping for nine hours". "Since" refers to periods of time that began in the past and continue to the present. "From" and "until" are often used together to specify time ranges, like "The shop opens from 8:00 to 18:00". Exercises are included for the reader to practice using these prepositions of time correctly in sentences.
