How would you feel if you received a large amount of money all at once？

    That's exactly what happened to Nkosikho Mbele，a worker at a gas station in South Africa.His sudden luck was brought about by an act of kindness he did for a young woman﹣Monet，a company manager.

    One day.Monet stopped at the gas station to refuel（加油）.But when Nkosikho was about to serve her，she realized she didn't have any money or cards on her.She immediately tried to stop him.Knowing about her trouble，Nkosikho decided to pay her gas bill of about R100 （＄ 7）to make sure that she could travel across the highway with enough gas.

    "Madam.I'll pay for you so that you won't run out of gas on the road.Whenever you are near here again，you can just give me back the money，" Nkosikho said.As for him，the R100 was almost all be made in a day.He had to support a big family.He needed the money very much.He wasn't even sure if Monet would come back to return his money，but he still volunteered to help her.

    Several days later，Monet came back with his money and a box of chocolate.She was so thankful that she also posted their story on the Internet.Great changes took place.Nkosikho became famous in his town.Many people were moved by his act and offered to raise money for him.Nkosikho received around ＄ 24，000 as much as about his salary（薪水） of eight years.His boss also heard of his kind act and decided to give him a rise in salary.

    "I feel like I'm dreaming.My life has been turned﹣upside down，" Nkosikho said thankfully.As normal people，we can bring a great change to life by doing a small good thing.
