【推荐1】What is color? Why do some of the things around us look red, some look green, but others look blue?

Colors come from reflected light (反射光). We see colors because most of the things reflect light. Something is red, because it reflects most of the red light. In the same way, if something is green, it reflects most of the green light. If something reflects all light, it is white.

Some of the light is reflected, but some is taken in (被吸收) and turned into heat. Dark colors take in more light and reflect less (更少的) light. So dark-colored clothes are warmer than light-colored clothes in the sun.

【推荐2】More than 50,000,000 people live in the rainforests（热带雨林）of the world. When we cut down the rainforests, we destroy（摧毁）the home of the people living there too. In 1900, there were 1,000,000 people living in the Amazon forest. In 1980, there were only 200,000.

The Yanomami live in the north of Brazil. They have lived in the rainforest for about 10,000 years and they use more than 2,000 different plants for food and medicine. But in 1988, someone found gold（金子）in their forest, and suddenly 45,000 people came to the forest and began looking for gold. They cut down the forest to make roads. They made more than a hundred airports. The Yanomami people lost land and food. Many died because new diseases（疾病）came to the forest with the strangers.

In Borneo, people were cutting down the forest to sell the wood. The Penan people tried to save their rainforest. They made blockades（障碍）across the roads into the forest. In 1987, they closed fifteen roads for eight months. No one cut down any trees during that time. In Panama, the Kuna people saved their forest. They made a forest park and visitors pay to visit it. The Gavioes people of Brazil use the forest, but they protect it as well. They find and sell the Brazil nuts which grow on the forest trees.

【推荐1】When we have our ups and downs, pains and joys, friends are always the first choice that we want to share those feelings with. We will feel much better after sharing those feelings, and we will also get more happiness and less sadness. Here are some ways to make new friends.

Be friendly to others. Smile at others and you are sure to get a smile in return. We should try to make others feel at home. That is exactly the first step of making friends.

Realize your fears. Some of us think meeting new people as a terrible event. We are worried about how to make a good impression, how to keep the conversation going, and so on. Actually, all these fears are just in our mind.

Be yourself. Changing yourself to make new friends is not wise. Just be yourself. We can meet real friends when we are who we are. The truest friendships are built with both accepting each other for who they are.

The new and publicly-available ChatGPT is a type of AI that has been “trained” by looking at over 8 million web pages. When asked a question, ChatGPT uses this training to produce detailed answers that often seem like they were written by a human. You can ask it anything and it will give you answers to not only follow-up questions but also professional questions (although it does sometimes make mistakes). You can also ask it to write text, such as short stories or essays. The technology is so promising (有前途的) that some people believe it will overtake (超过) Google in the near future.

For many years it has been expected that AI will become an important part of our lives, and for just as long there have been concerns (忧虑) of the trouble that AI could cause. In the 20th century, scientists, philosophers and writers sometimes worried that AI would become too powerful. In the short story I Have No Mouth, and I Must Scream, a giant supercomputer has killed every human on earth except five people it keeps to torture (折磨). And in the 1984 film The Terminator, a powerful AI called Skynet uses time travel to send a robot into the past to try and kill the mother of a brave and strong fighter. On the other hand, some people were optimistic of advanced technologies’ potential (潜力) to build a better world. In the 1960s TV show Lost in Space, a family of humans were helped by a friendly robot named Robby.

Nowadays, there is less concern of an all-powerful AI trying to destroy the world, and we are not expecting friendly robots just yet. That doesn’t mean there is not a lot of excitement and concern being felt towards new technologies like AI, though. ChatGPT is a great example of a modern technology that is causing mixed feelings.

It’s too soon to say what kind of influence ChatGPT will have on our lives. Let’s hope that, if ChatGPT does become bigger and more popular, its effects are mostly positive. So, what do you think? Will ChatGPT be good, bad, or somewhere in between for humankind?
