Mrs. Smith is an unusual teacher. Once she told each student to bring along a few potatoes in plastic bag. On each potato the students had to write a name of a person that they hated And the next day, every child brought some potatoes. Some had two potatoes；some three；some up to five.

 Mrs. Smith then told the children to carry the bags everywhere they went, even to the toilet, for two weeks. As day after day passed, the children started to complain(抱怨)about the awful smell of the rotten（腐烂的）potatoes.

 Those children who brought five potatoes began to feel the weight trouble of the bags. After two weeks, the children were happy to hear that the game was finally ended. Mrs. Smith asked,“How did you feel while carrying the potatoes for two weeks?” The children started complaining about the trouble loudly．

Then Mrs. Smith told them why she asked them to play the game. She said,“This is exactly the situation when you carry your hatred（仇恨）for somebody inside your heart. The terrible smell of the hatred will pollute your heart and you will carry something unnecessary with you all the time. If you cannot stand the smell of the rotten potatoes for just two weeks, can you imagine how heavy it would be to have the hatred in your heart for your lifetime? So throw away any hatred from your heart, and you'll be really happy．

Time spent in a bookshop can be enjoyable. If you go to a good shop, no assist ant will come near to you and say, "Can I help you?" You needn't buy anything you don't want. You may just try to find out where the book you want is and read it. But if you fail, the assistant will lead you there and then he will go away.①It seems that he is not interested in selling any books at all.

There is a story which tells us about a good shop. A medical student found a very useful book in the shop. ②But it was too expensive for him to buy. He couldn't get it from the school library, either. So every afternoon, he went there to read a little at a time. One day, however, he couldn't find the book from its usual place and was leaving when he saw an assistant singing to him. To his③      , the assistant pointed to the book in the corner. "I put it there so that it couldn't be sold out."said he assistant. Then he left and the student went on with his reading.

    How do you turn your interests into a business (生意)? Mohammed Ali, 15, a teen gamer from Dewsbury in West Yorkshire, UK, is a good example.

    At the age of 12, he learned how to code (编程) by using YouTube and even made his own video game. Users have to pay 5.99 pounds (56 yuan) per month to play the game. He has already made 30,000 pounds. He also makes websites and is working on a finance app (理财应用软件), which will be open to the public in August.

    Ali has saved lots of money for his future university costs and even bought two sofas for his family's living room.

    "When I first started making money, I thought I'd just spend it all. Then I thought, why should I spend it all? I save most of it in the bank, because I want to do more in the future," he told the Daily Mail.

    He became interested in computers when his parents bought him one at the age of 6. He often played video games on his computer. But after playing so many games, he decided to make his own.

    Then, Ali learned how to code using YouTube videos and by reading books on the subject. In 2012，he made his own game called Project 2006 after working on it for seven months. It was a role-playing game and more than 3, 000 people are members. After his game became popular, he started a website-making business.

    In the future, he wants to go to university and study computer science. "I'm looking forward to studying computer science, not business because I've got a lot of experience in business already," he told the Daily Star.
