Based on the pictures, here's a possible interpretation of the situations:

1. Image 1: An eight-year-old child is excited for a trip. As they rush downstairs, they fall and break their arm.

2. Image 2: While riding a bike on holiday, a big dog runs towards the rider, causing them to fall into a river.

3. Image 3: During a mountain walk with friends, someone finds £20 on the ground and decides to buy lunch for everyone.

4. Image 4: In class, a student's mobile phone rings, which leads to the teacher explaining school rules and giving them their first punishment.

These images seem to depict scenarios for discussing events and consequences.
