Teenagers have a lot of new ideas. Let’s have a look at these teenage inventions that might change the world.
Banana leaves usually go bad in two or three days. Tenth Hadith, a teenager from India, used UV to make the leaves stay fresh for a year. Tenth thinks that one day the leaves will be used for making plates, cups and other things. |
David Cohen, an American teenager, built an earthworm(蚯蚓) robot. It is able to go into the smallest places, where humans or dogs can’t go. It will be used for finding people in a fire or an earthquake. |
Remya Jose, a 14-year-old girl from India, found it tiring and boring to hand wash clothes in the nearby river. She reused some bicycle parts and created a washing machine that saves time, energy and keeps people fit at the same time. |
Kenneth Shinozuku, a 15-year-old boy from New York, noticed that his grandfather who got Alzheimer’s disease(老年痴呆)would often leave home and get lost. So he invented the wearable sensors(感应器)to help people find their family members like his grandfather. |

I knew I was not supposed to be quite so excited. I was too old for that. At age eleven, the oldest and my mom’s “grown up” girl, I had to keep calm. I was in middle school after all. But every chance I got, when I was alone, I_______ each present under the tree. I read every tag(标签)and felt every bag, guessing at the things within. I had examined each gift so often that I could tell which ______ went to which person without looking at the tags.
It had been a hard year for my family. Whenever my mom looked over at the tree and presents, she would sigh(叹气)and warn us, “There won’t be as much for Christmas this year. Try not to be______ .” Christmas had been a time for my parents to spoil(宠爱)us. I had heard the phrase “giving is better than receiving”, but getting presents was the whole point!
On Christmas morning, we ______waited in the hallway until Dad told us everything was ready. We rushed into the living room and had to wait and ______ while other family members opened their presents, but as the time passed we lost our self-control.
“Here’s another one for you,” said Mom as she handed me a bag. I looked at it, confused. Having spent so much time examining the presents before Christmas, I______ this one. It was for my mom!
It was a blow dryer. While this may seem only a simple gift, to me it was so much more. But, in my world, where receiving was more important than giving, my mom’s act of selflessness was difficult to_______. I thought in disbelief about how much my mom must love me to do that.
I have always remembered that Christmas with love. As an adult with children, I can now see my mom was finding an even greater_______in her Christmas because giving truly is better than receiving. To me, my mom’s simple act meant the world.
