After replacing the broken timing belt which also sheared off the crank shaft sensor, I was told that three of the motor mounts needed to be replaced. The car was not vibrating or roaring before the belt broke. Could the belt breaking cause the motor mounts (that had been replaced less than a year ago) to break?

when doing a timing belt, you need to remove the upper mount to jack up the motor for acess to the front of the motor.
in that process, the tech may have seen the mount cracked from age.
no, the belt does not cause the mounts to go bad.
did he reccomend all the mounts??

When I got the car back they didn't say anything about there being broken mounts. I started the car and could not believe the noise so I asked the head mechanic to tell me why it was not making so much noise. He and another tech looked and thought maybe one mount was broken. They then took it back into the shop and decided that there was one broke mount. They replace one mount. I picked the car up later and it still made the noise. I was told the noise wasn't so bad in drive. They must not have driven because it was the same. I took it back and then they decided I had two or three more broken mounts.

i am going to assume that there was no issue prior to the repair.
you need to talk to the manager about it. have someone else examine it and determine the noise and why.
the repair was labor intensive and he may have missed something.

when they replace the timing belt, they probably did not align the silent shaft properly, this is what is causing the vibration
