- you enumerate a series of past actions which happend one after another:
   "She came home, switched on the computer and checked her e-mails."
- you just want to mention that an action took place in the past:
   "Collin visited us yesterday."
- two past actions happened at the same time:
   "Simon was playing on the computer when his brother was watching TV."
- you want to put emphasis on the progress:
