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．

    An Englishman was showing a foreign visitor around London.“What's that strange building?” asked the visitor.“That's the Tower (塔) of London.”“I see. How long did it take to build it?”“About 500 years.”“In my country we can build it in a few months.”said the visitor. After they came to St. Paul's Cathedral (大教堂), the visitor asked the same question. “Nearly forty years,”said the Englishman. “In my country we finish it in forty days at most,” said the visitor. This went on all day. They visited most of the best known buildings in the city. Every time they saw a new one, the visitor asked what it was and how long it took to build it. Then he said they could do the same thing much faster in his country. At last the Englishman got angry with the visitor though he tried not to show it. Several days later they came to the House of Parliament (议会) and the visitor asked his usual question, “What's that?” The Englishman answered, “I have no idea. It wasn't there last night.”

    We were on a visit to Monkey Island. Jim thought we should try water skiing(滑水).

    We can get a boat and ski at Monkey Island.

   Don't go water skiing near Monkey Island today,” said the woman standing near the boats. “There might be sharks（鲨鱼） in the water.”

    “I don't think so.” said Jim who thought he knew everything.

    “I wouldn't go water skiing in the sea near Monkey Island today,” said the man with the woman. “They saw sharks in the water yesterday.”

    “The sharks won't hurt me,” said Jim with a big smile on his face.

      Another man getting out of a boat said, “I'm sure we just saw a shark in the water a few minutes ago.”

    “Don't worry about me,” said Jim. “I don't worry about sharks.”

    Jim and his two friends, Bill and Bruce pushed the boat into the water. Jim was driving the boat. He drove very fast and sprayed water on everyone standing near the boat.

    Jim drove the boat to the middle of the sea near Monkey Island. Everyone could see him and the boat. He wanted to show everyone how well he could water ski.

    “You drive the boat, Bill,” Jim said. “Bruce, you watch me and the rope while I water ski.”

    “What about the sharks?” asked Bill.

    “Forget about the sharks,” said Jim. “I'm not afraid of sharks.”

    Jim got into the water. He was putting his feet in the water skis. Then Jim felt something large and hard touch his leg as it swam past him. Suddenly, a brown fin(鳍) moved through the water towards Jim.

    Later, when Bill and Bruce stopped laughing, they said, “We never saw anyone move so fast! You were running on top of the water to get back in the boat! You even left the water skis in the water.

    “There it is again! Shark! Shark!” cried Jim.

Everyone laughed—even the people standing on shore.

    The dolphin（海豚） came to surface again, took a deep breath, smiled at Jim and went back down into the deep water.

    A farmer had a cow. He took very good care of this cow and one day when it was ill, he was very worried. He telephoned the vet.

    "What's the problem?" The vet asked him when he arrived.

    "My cow's ill," the farmer said. "I don't know what's the matter with her. She's lying down and won't eat. She's making a strange noise."

    The vet looked over the cow. "She's certainly ill," he said, "and she needs to take some very strong medicine."

    He took a bottle out of his box, put two pills into his hand and said, "Give her these. The pills should make her better."

    "How should I give them to her?" the farmer asked.

    The vet gave him a tube (管子)and said, "Put this tube in her mouth, then put the pills in the tube and blow. That'll make it."

    The next day the vet came to the farm again. The farmer was sitting outside his house and looked more worried.

    "How's your cow?" the vet asked.

    "No change," the farmer said, "and I'm feeling very strange myself."

    "Oh?" the vet said, "Why?"

    "I did what you said," the farmer answered. "I put the tube in the cow's mouth and then put two pills down it."

    "And?" the vet asked.

    "The cow blew first," the farmer said.
