From time to time
To breathe as a sign of relief
It´s strange, but true!
Day after day
To send shivers sown someone´s spine
To go from bad to worse
Rumour has it
All of sudden
Often
To become more and more difficult or unpleasent
Everyday/ Frecuently
People say...
From one moment to another
To be very glad that something has ended
To make someone very scared
To be so weir that people may not believe it
