Shyness once took over my life. When I was 13, in my French lesson, my teacher told us to ________ ourselves speaking out our families. I recorded myself with confidence. When I pressed “play” to listen back, I ________ my strange voice—just like a little kid. That made me very shy and I ________ attending events from then on.

Years after that, I became a teacher in a primary school. On the first day, my hands could not help but sweat（出汗）. The weight of my arms was trying to prevent me from ________ the door. Though a little ________, I opened the door slowly. ________, a wave of laughter flew through the air. Then I ________, and felt it was a bad ________ to be a teacher. They did not seem to mind me at all. After class, a little girl walked up to me and asked, “Could you ________ me to read this?” with the most ________ face I have ever seen as if she had just gotten a cookie. “I like your voice!” she said. I shook my shyness off and my body felt as ________ as a feather（羽毛）. Perhaps this was not such a bad idea after all.

Besides, there was one simple thing that ________ me most. Every day when the students left, they would clean up after themselves and leave their areas ________ without ever being told to do so. Actually, they ________ very well. Looking back it now, I would have to say these students gave me one of the greatest ________ of my life.

In the future, I want to create a space for shy people like me to shine.

Zhou Jiangtao passed away at only 17 years old. He got bone cancer (癌症) when he was 13. Four days before the announcement of his death, he asked to donate his organs (器官). “I do know the pain of suffering from disease and the helplessness of having no cure (治愈方法) ...I’ve seen so much sadness and regret and want to offer help.”

On the day he “left”, two patients who had been waiting for cornea transplants(角膜移植) were told they would get donations. Zhou’s body was moved to Zhejiang University School of Medicine on the same day.

It has been 12 years since China started a national pilot (试点) program for human organ donation. According to the China Organ Donation Administrative Center, about 300000 people across China are waiting for life-sustaining(维持生命的) organ transplants, but only 20, 000 receive transplants each year.

In recent years, organ donation and transplantation have gotten more public support in China. As of April 2, more than 4. 62 million people had signed up (登记) for organ donation, said the center. As many as 75 people can benefit from a single donor(捐献者). There’s no age limit (限制) to donation, while people under 18 need a parent’s consent.

In China, there are some deeply rooted traditions about the bodies of dead people. For example, many believe the body is a gift from one’s parents. So, they think dead bodies must be kept complete.

But many others have changed their beliefs. Donating organs is a way to help others and extend (延展) the meaning of one’s life. Increased willingness (意愿) has been seen among young and middle-aged people, noted People’s Daily. “Dedication(奉献) makes life more precious (宝贵的) than oneself, ” Zhou once said.

Is there a way to quickly recall information just before taking an exam? Walking backwards might be a solution. Scientists from the University of Roehampton in the UK said this activity can help people improve their short-term memory.

Researchers asked 114 volunteers to watch a video. After watching the video, participants were divided into three groups. One group was told to walk 10 meters forward. The second group walked 10 meters backward. The third group stood in one place. All three groups were then asked 20 questions about what they saw in the video.

The scientists found that the backward-walking group got two more answers correct on average than the other two groups.

This suggests that the link between the concepts ( 概念 ) of time and space is important in terms of ( 就……而言) how our minds form memories. “Time is really expressed through space,”

Aleksandar Aksentijevic, who led the study, told the Daily Mail. When you walk backward, you see things from a different angle ( ⻆ 度 ) compared to walking forward. This difference helps people recall things that happened in the past.

And walking backward is not just good for the brain. It is also good for the rest of the body. Compared to walking forward, walking backward is more challenging. This can help us improve our health, says New Scientist. Walking backward uses more energy in a short time and burns more calories (卡路里).

In addition, walking backward is less stressful for our knees. It could be helpful for people who often have pain in their knees, according to researchers from the University of Oregon in the US. Walking backward also keeps our backbones strong, which can help to lighten pain in the lower back. This might be why many old people like walking backward.

The invention of barcodes（条形码）is based on a very simple idea. We only need to give each product a specific number and print it.

    51     We could simply print the number itself. But this can cause problems. For example, an unclearly printed “seven” could look like a “one” to a computer. It’s also true for “three” and “eight”.     52     We need a better way of printing numbers so that they can be read correctly at high speeds. That’s the problem barcodes solve.

Each number in a barcode is shown by seven blocks of the same size.     53     For example, the number “one” is shown in turn by two white stripes（条）, two black stripes, two white stripes, and one black stripe.     54    

A barcode includes different parts and each one provides a specific meaning. The first part of a barcode tells you the country where the product was made. For example, 690-692 is the barcode for China.

    55     The final part is about the product itself. This is how barcodes work.

During the last few years of his life, my dad lived just up the road from me in a tiny house. He had been alone for over 20 years after losing my mom. His own mother had recently passed away too. He was disabled and retired, so he spent a lot of time alone.

Several times a week, though, I would take a walk up to his house. We would sit in the living room, drink tea and talk. It wasn’t anything big. We talked about sports, cars, gardening, weather, and enjoyed a laugh over old memories. It wasn’t anything too deep. It was just a simple sharing, a connection between a father and a son, an hour spent just enjoying each other’s company. Those afternoons remain some of my happiest times spent with my dad. It allowed us to gently heal (治愈) any old wounds we had given each other when I was growing up. It allowed us to silently give each other time and love. It allowed us to grow closer together before he left this world.

I know that when my own time in this world is done, I will get to spend another afternoon with my dad. We will sit, talk, catch up, and quietly enjoy each other’s company. We will share all the love we didn’t get to share. And we will remember that afternoon forever.

If there is one thing that I learned from those afternoons, it is this: It is never too late to spend time with those you love. It is never too late to tell them that you love them. It is never too late to heal a relationship and mend a hurting heart. Begin today! Spend an afternoon with those you love and those afternoons will become a lifetime.
