Do you ever find yourself standing in front of rubbish bins, not sure whether the piece of waste in your hand is recyclable or not? To solve this problem, four Hong Kong high school students have invented a smart rubbish bin that uses AI to sort(分类) the waste. The students named the bin Waste Collection Point.
Connected to a computer, the bin uses a camera to tell the kind of the waste it receives and sorts it into plastic, paper, glass, or other kinds. To make sure the bin can sort waste correctly, the team tested every product in the school shop and took at least500 pictures of each one. “To train the AI, we had to take many photos from different angles(角度), so it has a better rate of accuracy,” said one of the students who built the AI system.
The idea of the smart bin was born two years ago, when the students were in Grade Ten. At that time, people from the city crowded into their village because of the COVID-19. They left behind a lot of rubbish and caused more pollution.
“All the bins were full, and there was even rubbish on the mountain,” the students recalled, “Every weekend, we had to join the villagers in picking up the waste.”
The students decided to develop a special recycling bin that would encourage people to protect the environment. Although school ended at 2 pm, the team would continue to work on their invention until 6 or 7 pm at school. Even when their school was closed last year, they would still meet and work together online.
“Our bin is now in its third generation(代). Before graduation, we hope it can be widely used in the city.” The students said, “Then it will be easier than ever for people to recycle and protect our environment.”

If you want to watch and know something about birds, you must find a good place near the bird nest（巢）.
Birds sit on eggs and take care of their babies from April to June. Because the baby birds are too young to leave the nest, parents often go to look for food and come back in several minutes. So it is good to watch birds. When we watch birds, we’d better hide ourselves in a close place to the nest, and it’s better to use binoculars(双筒望远镜).

a) Each nest must have six boards（木板）. Don’t make the boards too slippery（滑）.
b) Dig a small hole in the front of the nest as a “door”. The “door” is big enough so that birds can fly in or out easily.
c) Make sure the rainwater can’t go into the nest.

Some people think that all wild animals are danger (1). In fact very few of them will attack a man if he leaves them alone. If you met a lion or an elephant, you would run away. But even a lion will avoid a man unless it is very angry. （2）(狮子和老虎只杀死并吃掉人类) when they have grown too old to catch their usual food. Some animals get frightened if they only smell a man. Some stand and look at him for a while before they run away. Some take no notice at all but quietly walk in another direction. Wild animals only attack a man when they are afraid that he means to hurt their babies, or when they are shot at and made angry.
