| Dear Netters! Sometimes mistakes occur in compound sentences with the misleading conjunction 'since'. For example: But...as for me, being honest, I usually sleep less than 4 hours a day and when I'm totally exhausted (this is my normal state since I've entered the RSU), I just close my eyes and sleep no matter what is going on around. The underlined clause contains a grammar mistake. The correct version is to use the Past Indefinite (Past Simple) tense form: ...since I entered the RSU... Because it means ....the moment/time that I entered the RSU.
The Present Perfect is a must when the clause indicates the time period which has not finished yet, i.e. 'since' means 'still now/because/as', for example: 'Since I have been in RSU for the last three years, I feel I am tired....' Look at the additional examples: 'Since I was eight, I started going to the boxing club'. I have been learning English since I was 14. 'Since I haven't understood what you have said, I think you must explain again' We have been friends since childhood. I mean we have known each other for so long... Last! Pay attention to the commas: - no comma if the sentence starts with the main clause - a comma when the sentence starts with the subordinate clause.
