By Bicycle or on Foot骑自行车还是走路

It was a sunny day.John and Tom decided to go fishing in the country.Because they had no bicycles,they had to go on foot.When they were walking under the sun sweating all over,Dick overtook them from behind on his bicycle.Waving his hand,he said proudly,"No hurry!"
John and Tom took no notice of Dick's words and kept on walking.After one mile or two,they saw someone repairing a bicycle by the roadside.It was Dick.His bicycle had broken down,with one of the types flat!
Dick could not fix his bicycle,so he had to push it along.When he finally got to the fishing place,tired and depressed,John and Tom had been enjoying themselves for quite a long time.
