One day,Nick invited his friends to supper.He was cooking some delicious food in the kitchen.Suddenly,he 1.(find) that he had run out of salt.So Nick called to his son,“Go to the village and buy some salt,but pay a fair price for it: neither too much2.too little.”

His son looked surprised.“I can understand why I shouldn't pay too much.Father,but if I can pay less,3.not save a bit of money?”

“That would be a very4.(reason) thing to do in a big city,but it could destroy a small village like ours,”Nick said.

Nick's guests,5.had heard their conversation,asked why they should not buy salt more cheaply if they could. Nick replied,"The only reason a man would sell salt6.a lower price would be that he was desperate for money. And anyone who took advantage of that situation would be showing a lack of respect7.me sweat and struggle of the man who worked very hard to produce it."

"But such a small thing couldn't8.(possible) destroy a village."

“In the beginning,there was only9.very small amount of unfairness in the world,but everyone added a little, always10.(think) that it was only small and not very important,and look where we have ended up today.”
