Once there was a rich man who lived in a beautiful castle near a village. He loved people there and 1. t his best to provide help. He planted beautiful trees near their houses, and every year he even gave away a Christmas tree. But people there were still 2. u because they were not rich enough to live a comfortable life.
One day this man got up early, and placed a large stone in the road. Then he 3. h himself behind the bushes and waited to see what would happen. Soon a poor man came along. He screamed angrily because of the stone in his path, but he walked around it and 4. c his way. Then a farmer came. He complained but drove around it too. The day passed. 5. E who came by complained, but nobody touched the stone.
Just at nightfall, a boy came. He was very 6. t because he had been busy at the factory all day long. He said to himself, “It is almost 7. d. Somebody may fall over this stone, and perhaps be 8. b hurt. I will move it out of the way.” He pulled, and pushed. At last he moved the stone. To his surprise, he found a bag of gold lying 9. u it. It said, “The one who moves the stone 10. o me.”
The boy went home happily. The rich man finally found out the cause of the villagers' poorness—they were too lazy and selfish.

Paying for bus rides with plastic usually makes people think of plastic bus cards. 1. B one Indonesian city has decided to accept recyclable plastic waste 2. i of money for city buses.
Surabaya, Indonesia's second largest city, located on the eastern end of the country's main island Java, made this decision in April, 2018. Now the 3. l can pay for their bus rides by putting plastic cups or bottles directly on the bus. A two - hour bus ride costs 10 plastic cups or 5 plastic bottles.
Indonesia is the second largest ocean plastic polluter, producing 4. u to 2.4 million tons of plastic waste into the ocean every year, according to a report. The head of Surabaya's transportation department said, “With this 5. d, we hope to raise public awareness about the environment, 6. e people's awareness about plastic waste.”
The collected bottles are 7. s to recycling companies and the money earned from it goes toward running the bus companies and providing money for green spaces in the city. This is certainly turning rubbish into 8. t.
The decision is part of the city's 9. p—to become plastic waste - free within a few years. In order to encourage local people to take buses, the city also added new Suroboyo buses. They are air - conditioned, comfortable and easy for elderly and 10. d passengers to get on and off.
This type of programme can be a model for other cities worldwide and encourage citizens to recycle their plastic waste.
