| We usually brush our teeth without thinking too much about what we're actually doing. To make sure our focus is back to the task at hand, dentist Craig Kohler from the US created the world's first toothbrush with a built-in HD camera. It lets us closely see the inside of our mouth when we brush our teeth to get them cleaner than ever. The toothbrush can be connected to smartphones and tablets with Wi-Fi and Bluetooth. We can even zoom in and out of certain areas of the mouth. |

It can kill germs (细菌) and viruses, including the coronavirus, in 10 seconds. According to the World Health Organization, UVC (短波紫外线) light can cause skin and eye damage. But UVLEN uses a UVC light with a wavelength between 207 to 222 nanometers (纳米). It is said to kill germs without harming your skin. |
| An invention that combines a broom and vacuum (真空吸尘器) has been created. It looks like an ordinary broom, but its designers say the Vabroom will clean up common household dirt and debris (垃圾碎片) — all without a dustpan (簸箕)! The vacuum is really easy to use. Just tilt (倾斜) the broom — you don't even need to bend over — and press the vacuum part to the floor. It is powerful enough to deal with most debris, including glass and candy. |
| Lei Tao, 16 Friendship is founded on interaction (互动), and the interaction sometimes needs intentional ideas. If none of the friends are willing to step forward to communicate, the relationship will gradually disappear. For example, this term, I transferred (转) to a new class, and those classmates who I used to treasure began to grow distant from me. It's a sad fact, and we should learn this lesson to better improve our friendships. | Wang Hong, 16 Some people say that true friends can understand each other with only a smile. I have to point out that this kind of friendship is rare. Friends usually need to express themselves to let others learn more about them. What's more, if there is a misunderstanding between two friends, the friendship will be easily broken. However, friendships can be kept and improved if they talk more, play together more or send gifts to each other. |
| Chen Yuhao, 16 I think friendship is a natural relationship that makes people feel comfortable. It depends on people's similar hobbies, so friends will naturally get along well with each other. According to that, friends learn quite a lot about each other and understand each other's meaning with only a smile or eye contact. True friends will gradually become a part of our life. | Sun Yanxue, 16 Sometimes, intentionally protecting the friendship seems to develop a relationship. But this kind of friendship is fragile (脆弱的). It can be broken if there's something wrong. Humans are greedy (贪婪的). Once friends get used to the gains, they may distance themselves from us if we stop showing our kindness one day. As a matter of fact, the key to keeping friendship is based on understanding each other. |

| The Sanxingdui Ruins were found by accident. A farmer found them in 1929 when he was digging the ditch (挖渠). People found some artifacts, but didn't know how important they were. After 1986, some experts thought these pits were used for sacrifices (祭祀). But they were not sure. The new findings showed that they were right. In October 2020, the newest relics were found in six pits. A group of researchers began to unearth (发掘) them. | Where do we come from?
