A man went to a farm.While he was there,he saw a pig with a wooden leg.This surprised him so much.He decided to ask the farmer about it.

“This isn’t a common pig and l am very lucky to have him.”said the farmer.“Only two days ago there was a fire in chicken shed(鸡舍)when 1 was away from the farm.The pig noticed this and immediately let all the chickens out into the yard.He then phoned the firemen(消防员)and asked them for help.”

“AIso.a few weeks ago,when I was driving my truck down a steep hill,the truck hit a tree and 1 was badly hurt.The pig rushed to the truck and pulled me out of just before the truck caught fire.”

When the farmer was just about to tell another story,the man said,“Yes, yes,but what about the wooden leg?”

“Well.”said the farmer,“when you’ve got a pig as good as that,you don’t eat it all at once”

小题1:The pig lost a leg while he was trying to save the farmer’s chickens.
