Употребите герундий в функции подлежащего. 1. it`s so uncomfortable to sleep on the floor. 2. it`s great to meet old friends. 3. it`s impolite to speak in a loud voice. 4. it`s always useful to think.

я думаю, что тут скорее всего не герундий, а инфинитив надо в функции подлежащего, но 2 примера с герундием и инфинитивом.
