How do you say in Russian:
1. "I have to do a speech tomorrow" i.e. to speak in front of an audience.
2. "I have a formal invitation to speak в Высшей Школы Экономики* в России о кризиса Евросоюза" i.e. as speaker in seminar in front of an audience.
*Btw does anyone know this university? Is it a good university? Is it close to Moscow?
