During / For / Since / While

DURING      when we want to talk about something that happened:
                  My grandfather was killed during the war.
                  from the beginning to the end of a period of time:
                  During the summer she worked as a baby-sitter.

FOR            when we want to talk about how long something lasts:
                  The season only lasts for some months.
                  It can be used with all tenses:
                  They study for two hours every day.
                  They are studying for two hours today.
                  I worked at the bank for five years.
                  I've worked at this company for ten years.

SINCE         when we want to show points to the beginning of a period of time:
                  He has been living in London since 1997.
                  We've known about it since June.
                  It is normally used with the Present Perfect:
                  He has been here since his childhood.
                  It can also be used in the structure:
      It is a year since I saw her.

WHILE         when we refer to certain actions:
                  While I was eating lunch, I read this book.
                  Please,don't drink alcohol while driving.
                  It is always followed by a subject and a verb:
                 ...while the man was riding his bicycle.
                ...while the children were singing.

                  Both SINCE and FOR also have other meanings, with no reference to time:
                  This is for you.
                  Since he didn't study, he didn't pass the exam.
