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.”

What are you going to do if you are in a burning house? How will you escape? Do you know how to save yourself? Please read the following passage.
Escaping a fire is a serious matter. Knowing what to do during a fire can save your life. It is important to know the ways you can use and show them to everyone in the family, such as stairways and fire escapes, but not lifts.
From the lower floors of the buildings, escaping through windows is possible; learn the best way of leaving by windows with the least chance of serious injury.
The second floor window is usually not very high from the ground. An average(平均高度的) person, hanging by the finger-tips will have a drop of about six feet to the ground. It is about the height of an average man. Of course, it is safer to jump a short way than to stay in a burning building.
Windows are also useful when you are waiting for help. Be sure to keep the door closed. Or smoke and fire may be drawn into the room. Keep your head low at the window to be sure you get fresh air rather than smoke that may have leaked(渗) into the room.
On a second or third floor, the best windows for escape are these which open onto a roof. From the roof a person can drop to the ground more safely. Dropping onto cement(水泥) might end in injury. Bushes and grass can help to break a fall.It is important to ________.

We all enjoy the beautiful show of colours as leaves change each autumn. But did you ever wonder how and why this happens?
Leaves are nature’s food factories. Plants take water from the ground through their roots and take carbon dioxide (二氧化碳) from the air. Plants use sunlight to turn water and carbon dioxide into glucose (葡萄糖). Glucose is a kind of sugar, which plants use as food for energy and growing.
The way plants turn water and carbon dioxide into sugar is called photosynthesis that means “ putting together with light”. A chemical called chlorophyll helps photosynthesis. It gives plants their green colour. As summer ends and autumn comes, the days get shorter and shorter, and trees “know” to begin getting ready for winter.
During winter, there is not enough light or water for photosynthesis. Trees rest during this time and live on the food they store during the summer. They begin to shut down their food-making factories.
As the green chlorophyll disappears from the leaves, we begin to see yellow and orange leaves. Small amounts of these colours have been in the leaves all along. We just can’t see them in the summer, because they are covered up by the green chlorophyll.
The bright reds and purples we see in leaves are made mostly in autumn. In some trees, like maples (枫树), glucose is caught in the leaves after photosynthesis stops. Sunlight and the cool nights of autumn turn this glucose into a red colour. The brown colour of trees like oaks (橡树) is made from waste left in the leaves.
It is the mixture of all these things that makes the beautiful colours we enjoy during autumn. The word “chlorophyll” in the third paragraph means _______ in Chinese.
| A．叶绿素 | B．氧气 | C．胡萝卜素 | D．蛋白质 |
The leaves of the trees in autumn turn yellow because of the short of _____.
| A．water and carbon dioxide |
| B．glucose and energy |
| C．sunlight and water |
| D．sunlight and carbon dioxide |
The way that _______________________ is called Photosynthesis .
| A．plants change water and carbon dioxide into sugar |
| B．plants turn water and carbon dioxide into sugar with the help of sunlight |
| C．plants use glucose as food for energy and growing |
| D．chlorophyll is a great help |
Which of the following is NOT true?
| A．When autumn and winter come, the days get shorter and shorter. |
| B．During winter trees rest and live on the food they store during the summer. |
| C．During winter small amounts of yellow and orange colours are kept in the leaves all the time. |
| D．Trees begin to stop making food in summer. |
This passage tells us __________________.
| A．all the plants can grow well with the strong sunlight |
| B．there are all kinds of plants on the earth |
| C．all the colours of the leaves aren’t made from chlorophyll |
| D．maples and oaks have the same reason as other trees for the change of colours |
A group of swans flew down to a beach where a crow was jumping around. The crow watched them with disdain.
“You have no flying skills at all!” he said to the swans. “All you can do is to move your wings. Can you turn over in the air? No, that’s beyond you. Let’s have a flying competition. I’ll show you what real flying is!”
One of the swans, a strong young male, took up the challenge. The crow flew up and began to show his skills. He flew in circles, performed other flying tricks, and then came down and looked proudly at the swan.
Now it was the swan’s turn. He flew up, and began flying over the sea. The crow flew after him, making all kinds of comments about his flying. They flew on and on till they couldn’t see the land and there was nothing but water on all sides. The crow was making fewer and fewer comments. He was now so exhausted that he found it hard to stay in the air, and had to struggle to keep himself from falling into the water.
The swan pretended not to notice, and said, “Why do you keep touching the water, brother? Is that another trick? “
“No,” said the crow. He knew he had lost the competition. “I’m in trouble because of my pride! If you don’t help me, I’ll lose my life. . . ”
