Catch up
To do something you did not have time to do earlier
I need to catch up with my studies before the exam
Break down
To stop working or not be succesfull
My car broke down on the way to work
Hold on
To tell someone to wait for a short time
Hold on a second, I’ll be right back
Take over
To get control of something
She took over the project when the manager left
Look forward to
To feel pleased and excited about something that is going to happen
I’m really looking forward to my holiday
