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.
Teenagers’ technological inventions full of love and intelligence can make our lives easier and more convenient. Why not have a try?

June 5 is World Environment Day. Nowadays more and more people are trying different kinds of ways to face environmental problems around the world. What are people doing to protect our home—the earth?
Most people are changing their shopping habits. On the one hand, secondhand clothes may be a smart choice. People are willing to buy the secondhand ones to wear in special situations because they only wear them once or twice. On the other hand, there are some companies for renting (租) clothes and renting clothes is cheaper than buying them. So people are able to save money and protect the environment.
Several large companies have begun developing paper bottles to take the place of glass and plastic ones because there are lots of customers worrying about the environment. They think paper bottles have many advantages. The most important is that paper bottles are easy to recycle and weigh less than glass or plastic ones as well.
A zero-waste life is that people hardly create any rubbish. A zero-waste theme store provides a number of everyday, practical and pleasant zero-waste products. The store helps people start on a one-stop, zero-waste life journey. A zero-waste life follows the 6R principle (原则) —Refuse, Reduce, Reuse, Repair, Recycle and Rot.
All in all, the earth is our home and it’s our duty to protect it.
