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.”

Everyone worries. But how do you deal with your worries? Whether your worries are big or small, you can take these three steps to deal with your worries:
1. Try to find out what you're worded about
Sometimes, you will know what you're worried about. Other times ,you might not. Try to find it out first; if you can't, you can’t ask for help.
2. Think of ways to make it better
There is always something you can do to help you feel less worded. Sitting there worrying is no fun and it won't solve your problem.[
Grades at school are often top worries for kids. If you're worded about grades, ask yourself these questions:

★How do I get ready for class? Do I go over my notes even when there isn't a test?
★Do I have a good place to do my homework?
★ Have I tried different ways of studying?
If your worry is about a fight you had with a friend, you might write down all the things you could do: write a note to him or her, invite him or her to a basketball game, say sorry to him or her, etc. Once you have a list of things you could do, you can choose the one that gets your friend back.

One day, two young men went to a small city. They stayed outside a shop for a long time, and they seemed to have nothing to do. The owner of the shop felt they were unusual. So he used his new mobile phone to take a picture of them. After that he sent a message with the picture to the police. The picture surprised the police because the persons in the picture had done something wrong before. And the police were trying to catch them! A police car was immediately sent to the shop. The two young men were caught there. Later a policeman told the reporter, "We think this is the first time in the world that a picture message has been used to help catch criminals(罪犯)."根据

The world would be a very different place if someone hadn’t invented the lift. There would be few, if any, high-rise buildings because people would refuse to climb many stairs. By the time workers reached their offices on the top floors of a tower building, it would be time to go home – if they were not too tired for the long walk down！
The first lift that we know about was used by the Greek scientist, Archimedes, in about 230 BC. It was a simple place that could be pulled up and down with a rope. A lift like this was used much later in the 12th century by priests who lived on top of a mountain at Metereo in Greece. Because they were afraid of killers, the priests had not built any stairs up the mountain. The only way up was by lift, which priests worked from the top of the mountain.
A few hundred years later, a Frenchman, Villayer, invented a ‘flying chair’ which used a rope and a place. A number of rich people had these ‘flying chairs’ built in their homes, including Queen Anne of England in Windsor Castle and Louis XVI of France at Versailles. Unluckily, Louis’ daughter was badly hurt when using one of the chairs, and Villayer ran away, afraid that he would be punished.
The main problem for lift engineers was that either humans or animals were needed to pull the ropes. This problem was not worked out until the discovery of steam power. But even steam powered lifts were not always safe because they also used ropes which sometimes broke. If the rope broke - which it sometimes did - the lift fell to the ground and people in it were killed or hurt. This problem worked out in 1854 when an American, Elisha Otis, invented something which stopped the lift from falling if the rope broke. At first Otis lifts were used only in factories, then in 1857 he built one in a large New York store. Now lifts use electric power and are completely safe. They also travel very quickly. Some lifts travel faster than 60 kilometers an hour.The writer thinks that lifts are important today because __________.

When I was a foreign teacher in China, every day I taught English to my students and they taught me about China. One day the topic turned to saying “I love you”. I was shocked to learn that not one of my students had saidthis to their mothers, nor had their mothers said it to them. “Does your mom love you?” “Of course ,”they answered. 
How do you know?” was my logical question. They responded that their moms cooked and always toldthem what they were doing wrong to showtheir caring. I was stunned .So mom’s cooking and criticizing read out as “I love you”. “Then how do you say ‘I love you’to her?” They agreed that getting good grades, followed by god jobs would be how they showed their love.
I come from a culture where most people are expressive enough, so I repeated these queries in classes over time. Gradually, I began to get different response. Some of them had exchanged those sentiments with their moms.
One of my favorite stories of change came from a girl. When she came home from university, her mother met her at the door and hugged her. This had never happened before, but her mom said, “Now that you have gone I have more time to myself. I noticed that in some places mothers and children hug each other and I decided it was a good idea and that I would begin hugging you.”
In my family we all say “I love you” a lot .While it is true that we often say the words without having great depth of feelings at that moment, it is almost like a blessing we give each other. Those three little words carry a world of meaning, even when said as a greeting, but most especially if they are the last words we say to or hear from those we love.The foreign teacher_______.
| A．comes from America | B．is a young woman |
| C．is expressive enough | D．knows much about China |

| A．She is meeting her daughter at the door. |
| B．She loves her daughter and misses her. |
| C．She is glad that she has more time to herself |
| D．he finds it interesting to hug her daughter. |
What’s the main idea of the passage?
| A．Say “I love you” more to your family. |
| B．Say “I love you ” a lot to Chinese people . |
| C．Say “I love you ” as a greeting to others. |
| D．Say “I love you ” without great depth of feelings. |
Bananas don’t grow on trees. They grow on a stalk that looks just a little like a stalk of corn. The stalk is soft enough to be cut with a knife. 
It takes about a year before bananas are ready to be picked. Some are as small as fingers. Others are as long as men’s arms. Some banana plants grow as tall as a house – even taller!
Not all bananas are eaten as fruit. Some never get sweet, and they are cooked as a kind of vegetable.
People in most countries never see a banana until it reaches the store. But if you visited a country where it’s hot and rains a lot all the year, you might see a banana plantation, a large farm where bananas grow.
The tasty fruit doesn’t come from a seed but from a root planted deep in the ground. First a stalk pushes up into the air. The leaves grow. In the beginning the banana plant grows very fast – sometimes as much as the length of your feet in one night. Soon, sweet-smelling flowers come out, and when their flowers drop off, bananas begin to grow.
As they get bigger, bananas start turning up. It looks as if they’re growing upside down! Bananas are ready to eat when they turn soft and yellow. Bananas are picked long before this – when they’re hard and green. This is because bananas have to travel many miles before they arrive at a store. On trucks and boats and trains bananas travel all over the world. There are special boats just for bananas and special trains that keep them just cool enough so that they will get ripe while traveling. If bananas are picked when they are ripe (成熟的), they will spoil on the way.What’s the weather like in places where bananas grow?
| A．Dry and cold | B．Cold and wet | C．Wet and hot | D．Hot and dry |
The fruit of banana plants come from________.
| A．a stalk | B．a tree | C．a seed | D． a root |
Bananas are picked long before they are _____________.
| A．green | B．ripe | C．hard | D．red |

| A．All bananas are eaten as fruit. |
| B．Some banana plants grow taller than a house. |
| C．Bananas get ripe on their way to the store. |
| D．It takes about a year before bananas are ready to be picked. |
