As you may know, coral（珊瑚）is not a plant, but an animal. However, coral reefs（珊瑚礁）around the world are in danger. Here is a piece of bad news. Thailand will close one of its beaches to protect its coral from business activities for tourists. The beach is called Sunshine. It is so famous that many tourists put it on their wish lists. More than 5,000 visitors visit it a day. They arrive by boat. This does much harm to the coral reefs. Most of the coral has died. The beach will be closed between June and September to let the coral come back to life.
Experts say that 80% of Thailand’s coral reefs have been killed. Too many tourists cause a lot of pollution to these beaches. An expert said the biggest problems were hotels by the beaches, boats, and plastic waste in the sea. He believed the best choice was to close the beaches forever. He said, “I hope the government can take steps to protect the coral reefs. At the same time. I also hope all of us should try our best to protect the environment around us.”

Today, many teenagers have already put technology to good use. Here are two good examples.
• A new reader (阅读器) for the blind
The two 14-year-old students, Meng Shuqi and Feng Boyao, are from Taiyuan. They invented a new kind of reader to help the blind read books. The new reader can turn words into raised dots (盲点) when connected to a computer.
As we know, the blind read by touching raised dots. However, there weren’t many books for the blind in the past, and it was difficult for them to get new information in time. As the old readers in the market were very expensive and difficult to use, the two students decided to invent the new reader which was easier to use. They hoped that the new reader could be widely used to help more blind people.
• A smart system for the old
A 16-year-old American boy Vetri Vel created a smart system. It is made up of a small computer and a camera. The system can catch the heat signals (热感信号) of a fallen person and send messages for help at once.
After Vetri’s neighbor had fallen down alone at home, Vetri realized that falling down was a common problem for many old people. It may even lead to death. Vetri hopes that his invention can help more old people in time.
