A
Let’s look at two old but popular inventions we use in our daily life.
Band-Aids（创可贴）
The first Band-Aid was made by American Earle Dickson in 1921. The idea came to him by chance. Dickson’s wife Josephine often cut her fingers in the kitchen. At that time gauze（纱布） and adhesive tape（胶带）didn’t come together. People had to cut them to the right size. Dickson found they were always too big and soon fell off. So he put a piece of gauze on the center of a piece of tape. This is how he made the first Band-Aid.
Later Dickson’s new inventions became very popular all around the world.
Bubblegum（泡泡糖）
Bubblegum was invented by accident. In 1928, American gum company worker Walter E. Diemer played around with new chewing gum recipes. Chewing gum had already been invented more than half a century before then. But Diemer found that the gum he made was easy to blow. He blew a bubble and then saw the possibilities. He took some of his new gum to a shop and it sold out in a single afternoon. Since then, Dubble Bubble—the first brand of bubblegum—has made kids happy all around the world.

In 1994, a Japanese Masahiro Hara invented the Quick Response code (QR) as a way to increase the amount of information that could be stored on a paper label. Before this, one-dimensional (1D) barcodes had already been used since 1974 when the first barcode was codescanned in a supermarket in USA．The first barcode consisted of two parts: the barcode and the 12-digit number. But the two-dimensional (2D) code made by Mr. Hara can hold as much as 7000 digits or 4000 characters of text, including all Japanese characters. Many books have QR codes on their back cover which provide information such as the price, the author and the publisher.
Around 2006, Wang Yue and his team developed the Hanxin Code which can also encode Chinese characters. Short Hanxin Code, instead of long Chinese names, are now widely printed on the large quantity of shoes on trucks and ships. In 2014, Wang Yue’s company produced its first self-service QR code reader—the Smart Box. Now it has become the most popular offline payment in China.
QR codes can be easily read with any mobile phone that has a camera. So they are now widely used in factories and supermarkets, on various tickets and restaurant cashier tables. On 14 February, 2020, a QR code called “Health Code” is used in Hangzhou for people to quickly report their health status. Firstly, find an App named Alipay and scan the QR code included. Secondly, provide your name, phone number and ID number. Thirdly, answer some questions about your health status and whereabouts. Then you will get the “Health Code” with different colour, green for“being healthy”. Only with an updated green code, you may be allowed to enter or leave Hangzhou. On 21 February, 2020, a QR code is also used by Ms. Tang to inform her students about the course arrangement.

In India, there are many ironing vendors (熨烫商贩) who press people’s clothes for a living. Their main tool is an iron box powered by charcoal (木炭). India’s Science and Technology Department found out that there are about 10 million ironing carts (手推车) in the country. Each of them uses more than 5 kilograms of charcoal each day, Reuters reported.
After seeing her neighborhood ironing vendors throw the used charcoal away on the street side, Vinisha Umashankar, 15, told NPR that she started to think about the amount of charcoal burned every day and the harm it does to the environment. Burning charcoal gives out greenhouse gases such as carbon dioxide, which leads to climate change.
Vinisha, a student from Tamil Nadu, India, had the idea of ________. She spent six months designing a wheeled cart. The cart has solar panels (太阳能板) which take in sunlight to provide electricity. The rest energy can be stored in a battery for use on cloudy days, according to Time Magazine. Five hours of bright sunshine is enough to operate the iron for six hours.
To complete the invention, Vinisha lost herself in reading college-level physics textbooks to figure out how solar panels work. Then, she reported her idea to the National Innovation Foundation, run by the Indian government. Engineers there helped her build a full-scale working model, NPR reported.
Now, her invention is getting worldwide attention. “I am not just a girl from India. I am a girl from Earth,” Vinisha said in her speech. “All of us should understand that environmental problems are real and can’t be fixed at a later date,” Vinisha continued ,“There is no immediate stop. There are no magic ways.”
