Solution:
Let's complete Mac's homework with the correct past tenses!
- 1. Last year, Pops, Eva and I went (go) to Africa to look for an ancient magic drum. (This is a completed action in the past, so Past Simple is correct.)
- 2. When we arrived (arrive) at the airport it was early in the morning and the sun was shining (shine). (The arrival is a completed action, and the shining sun was ongoing when the arrival happened, so Past Simple for 'arrive' and Past Continuous for 'shine' is correct.)
- 3. While we were travelling (travel) across the country, we saw (see) lots of wild animals. Fantastic! (The travelling was an ongoing action, and seeing the animals happened during that time. Past Continuous for 'travel' and Past Simple for 'see' is correct.)
- 4. At midday we stopped (stop) near a lake to have lunch. (This is a completed action, so Past Simple is correct.)
- 5. Eva and I were standing (stand) near the water when Pops shouted (shout): 'Look out! There's a crocodile!' (The standing was an ongoing action when the shouting happened. Past Continuous for 'stand' and Past Simple for 'shout' is correct.)
Answer: 1. went 2. arrived, was shining 3. were travelling, saw 4. stopped 5. were standing, shouted
