Past Simple vs. Past Continuous

In this unit you study the difference between the past simple, the past continuous and the present perfect simple, let´s see when to use them.
- 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:
  "At six o´clock Simon was playing football yesterday."
  • Use both, past simple and past continuous when:
- you want to express that a new action happened in the middle of another action:
   "The telephone rang while I was having dinner."

Exercise 1: Group the sentences according to the tense used.
Exercise 2: Match the first part of the sentence to the second.
Exercise 3: Type the correct tense.
Exercise 4 and exercise 5: Put the verbs in the correct tense.
- you want to put emphasis on the result:
