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?

I'm my mother's third girl. When I was born, the doctor gently explained to my mother that my left arm was missing, below the elbow (肘). Then she gave her some advice, "Don't treat her any differently from others." And she did.

There are five girls in my family, and we all had to help out. Once when I was about seven, I came out of the kitchen, "Mum, I can't peel potatoes. I only have one hand." "Get back to peel these potatoes, and don't ever use that as an excuse for anything again!"

Of course I could peel potatoes — with my good hand and my other arm. "Jenny, if you try hard," she said, "you can do anything."

Once in the second grade, our teacher had each of us race across the monkey bar (攀爬架).

When it was my turn, I said no. Some kids laughed. I went home crying.

The next afternoon Mum took me back to the school playground. "Now, pull up with your right arm." She advised. She praised me when I made progress. I'll never forget when I was crossing the bar, the kids were standing there with their mouths open.

It was the way with everything. Mum had the courage to face anything. And she taught me I could, too.

The colorful clothes we wear today are made by machines. But what did ancient people do if they wanted to wear something colorful? Tie-dye （扎染）was a way to do this.

More than 1,000 years ago, the Bai people in Yunnan used tie-dye to dye their clothes. Then this skill became so popular that people gave tie-dye clothes to the emperor as gifts.

To tie-dye, you need to first use tools to tie, sew （缝制）, or clip （夹住）your cloth （布料）. The folded cloth is then put in dye. The Bai people usually make blue dye from a plant.

As the cloth is folded, some parts become dark blue, while other parts have a lighter color When you unfold the cloth, you will see beautiful patterns.

In the 1960s, tie-dye became a fashion trend in the US. People tie-dyed T-shirts and jeans imaginative ways. Many children in the US still learn tie-dye in their art classes.

At a recent famous fashion show, an Italian designer surprised people with tie-dye dresses, is like an experiment （实验）. People cannot imagine the patterns of the cloth if they don't see them. It's a surprise, the designer said. There is no doubt that the tie-dye trend has never really gone away.
