Let's say Yosef woke up late one day, and by the time he was ready to say kriyas shema, it was two minutes before sof zman kriyas shema (the latest time at which a person could say kriyas shema). He has time to say shema before time runs out, but he won't start shema before the time is over if he starts with the brachos.
What should Yosef do? Should he
- Say shema without the brachos?
- Start the brachos and say shema whenever he's up to it?
- Something else?
