Science and technology can be seen everywhere. They are making our life more convenient(方便的) and comfortable. Some scientists recently added amazing ideas to four common things and made great changes to them.
It’s not just a phone. China has taken the leading place in several scientific fields. In February, 2019, Huawei introduced Mate X, the first 5G phone that can be folded(折叠) in the world. It allows users to read e-books or watch movies on a larger screen. The Mate X supports(支持) 5G. It means you can get a movie from the Internet about 100 times faster than using 4G. |
They are not just chopsticks. Scientists at an American university have invented a pair of electronic chopsticks that can change the taste of food. When you put the chopsticks in your mouth, they can make you feel the taste becomes better, such as making sweet food taste sweeter or salty food less salty. Soon the scientists are going to try their technology on bottles, cups and spoons(勺子). |
It’s not just a sticker(粘贴). It’s said that about 52% of the fruits of the earth go bad before reaching the buyers. Scientists from Malaysia(马来西亚) thought of a simple way to solve the problem — tiny stickers that are made out of some natural materials(材料). Put the stickers on fruits, and the fruits can keep fresh up to two weeks. |
They are not just shoes. Every step you take is helping cut down air pollution. This is not in science fiction(科幻小说). A team from Europe has invented such a pair of shoes. The shoes can take in dirty air and send out clean air. If you wear the shoes and walk one kilometer, the shoes can clean the air polluted by eight cars. |
