Zdravím všechny,

můj student v rámci tréninku psaní napsal toto:

Since I got married I´ve shortened my sleeping about 1 hour in a day.

Což za mě není správně, chybí tam nějaká předložka, ale sám nevím jaká. Napadá mě maximálně FOR, ale zní mi to divně…

“Since I got married I´ve shortened my sleeping by about 1 hour a day.” This is grammatically correct and acceptable, but “shorten” and “sleeping” don't seem to collocate well when “sleeping” is functioning as a noun. “Shorten your sleeping time/hours” (when “sleeping” is fiunctioning as an adjective) is ok though. (Note: not “in a day” in the intended sense here)
