Sun Shines On Fun Run
On 12th June, a ‘Fun Run ‘took place in the town of Sunnyfield. A group of sixteen-years-old students from the local high school came up with the idea and over 500 people of all ages took part.
Luckily, it was a sunny day. Everyone had fun running, walking or skate-boarding the 10-mile distance. Thanks the event, 2,346$ was raised for the charity ‘Cancer Care’.
Suzie Hamilton, one of the students who organized the run, said, “We wanted to do something useful for others and this seemed the most fun thing to do.”
The local headmaster was so proud, he decided to make the event part of the school’s years calendar.

Who planned the event?
How many people took part?
What was the weather like during the ‘run’?
How far did they have to do?
What happened as result of the event?

G Listen to the reports. Number them in the order you hear them.

e.g. new technology 1
36. a rescue …
37. a new shopping centre …
38. school meals …
39. a bank robbery …
40. a sports event …
