These days schools don’t allow students to bring mobile phones to schools. Many parents are worried. How can they connect with their kids at school? Well, smart watches may be the answer to their worries. Smart watches are like small computers. They usually tell time and count a person’s steps(步数). Most smart watches connect with smartphones and they let the users make calls, and send and receive messages. Often smart watches have microphones and speakers. Some even have cameras.
Many parents buy smart watches for their children because they are too young to have a mobile phone. They are less worried because they can call their children at any time through smart watches. Also, many smart watches have GPS trackers(追踪器). These trackers allow parents to know where their children are, so they know if everything is OK.
But now some groups in Europe say many smart watches are not as safe as what we think. Some watches allow more than parents to track where the children are. They also allow anyone to send the children a message. People can also control the watches from far away to watch and listen to the children. To be safe, any time a smart watch makes a call or sends a message or GPS information-the information should be processed(数据处理) so no one else can get the information.

【推荐1】Type in “A cat wants to go to space” and ask the robot to write a bedtime story. Just one second later, you’ll get the story of Max, who clawed his way past many difficulties to sing among the stars.
This robot writer is real. It’s called ChatGPT. US company OpenAI developed it to generate (生成) human-like texts. It can translate languages, talk with people and write songs, poems and even jokes. It’s one of the most powerful AI of its kind, with the complete writing range (范围) of a real person!
People around the world have tried ChatGPT and posted their results on social media. Some used it to write history essays (论文), some asked it to take notes of presentations, and some even generated advice on how to interact (互动) with people at a party.
The power of ChatGPT lies in its speed and understanding of complicated (复杂的) matters. We may spend hours researching, understanding and writing an article on the theory of evolution (进化论). But ChatGPT can produce a well-written one in seconds. Another good thing about it is that if you ask dark, harmful questions, such as how to make weapons (武器), it will not give you an answer.
ChatGPT comes along at a time when AI is becoming increasingly able to do creative tasks. The materials they create are difficult to tell from those made by humans. This causes many issues (争论点) . These are the things that depend on humans to solve.

【推荐2】Long ago, as people got older, there was something wrong with their teeth and they would have a toothache.
Later people learned that cleaning their teeth was important, but they didn’t have toothpaste (牙膏）at that time.
About 100 years ago someone finally invented a kind of cream to clean teeth. Not long after that, the toothpaste tube (管子) was invented, so people could press the toothpaste right onto the toothbrush!
Today there are plenty of toothpaste choices: lots of colors and tastes to choose from, and some kinds of toothpaste are made just for children. When you are choosing a kind of toothpaste, make sure it has fluoride ( 氟化物).
Teeth are a very important part of our body. We will lose them forever once they are broken. So we must protect them.

【推荐3】Not all inventions are made by scientists. Kids can also make history with their inventions.
The state flag of Alaska was designed by 13-year-old Bennie Benson in 1926. His design was chosen from a flag-designing competition. It became the official flag in 1959. Bennie won a $1,000 scholarship(奖学金) and a watch.
Frank Epperson invented the Popsicle in 1905 when he was only 11 years old. It was called the Epsicle at that time. Frank left his drink outside the door overnight with a stick(木棒) in it. That night the temperature dropped and Frank’s drink was frozen. That didn’t stop him from tasting it, so today we have Popsicles to eat.
In 1642, Blaise Pascal designed the first counting machine when he was 18. The machine was for his father, a tax collector, to make his job easier. Blaise named it “the Pasealine”. He made about 50 of them, but nobody was interested in it. People thought it would take jobs away from them. 300 years went by, and the calculator(计算器) finally became a success. In 1968, the programming language(程序设计语言), PASCAL, was named after him.

The thing about space is that it’s impossibly huge. It took three days for the Apollo missions (代表团) to get to the moon. It takes between five months and a year to get to Mars. Of course, that’s still in our neighborhood. The nearest star is Proxima Centauri(比邻星) , which would take the Voyager spacecraft 8, 000 years to get to.
We’re not really built for space travel. We don’t live very long.
We need oxygen, warmth, water and food, space exploration (探索) is a really dangerous adventure (冒险活动).
When I was a kid, exploring space was a big deal. My first space exploration was to land on Mars. Honestly, I was expecting it to find alien life. Of course, so there were no living things or anything else.
And when the Space program was first announced, I believed that the future was on its way. Humans were going to explore the universe (宇宙), meet aliens and live on other worlds. And it was all going to happen in my lifetime. Of course, New Horizons, and Cassini. None of these missions have carried astronauts.
But we need to go on exploring the outer space. The next step doesn’t have to be Mars. It would be cool to find life somewhere in outer space.
On January 28, 1986, I watched the Space Shuttle Challenger take off. The teachers at my school had set up TVs so that we could get encouraged. Instead, we wanted more. We still do.

【推荐2】Robots are useful and taking place of humans in some areas because they never get tired and can’t feel pain. However, some researchers believe it’s a good idea to program robots to feel pain.
Researchers from Leibniz University of Hannover in Germany are working to develop an artificial（人造的）robot nervous system to teach robots how to feel pain. “Pain is a system that protects us,” said Johannes Kuehn, one of the researchers. “When we try to avoid the pain, it helps us not get hurt.”
Think about how many injures（伤害）you would receive if you couldn’t feel pain. Even though pain hurts, it helps us avoid danger and treat our wounds. The same will be true for robots. As a great number of people work closely with robots, the robots must behave in a safer manner. Kuehn believes that by protecting robots from damage, they will be protecting people as well. Damages to robots if left unseen could lead to workplace accidents.
Rather than feel pain, some robots are designed to show pain or see it in others. Asada, an engineer at Osaka University in Japan, and his workmates have made sensors（传感器）that pick up many types of touch signals. These touch and pain signals can turn into emotions and expressions on a robot’s face. Asada believes that these systems could finally lead to robots seeing the pain on human faces, an important skill for robots designed to care for elderly people, for example.
Antonio Damasio, a professor at the University of Southern California argues that programming robots with a sense of pain may cause an artificial sense of feeling to develop. But he says that this communication is not the same thing as a robot truly feeling and expressing emotions of pain. If one day, robots could actually feel as humans do. Damasio has a suggestion for the number one rule for robots: Feel good.

【推荐3】The temperature has dropped to 30 degrees below zero. But that doesn’t stop the fishermen of Songyuan City in Jilin Province. Each morning, they get up early and rush to Chagan Lake with a group of horses. The fishermen use the horses to help pull fishing nets out of the frozen (结冰的) lake.
For centuries, those living around Chagan Lake have kept alive the tradition of ice fishing. They dig holes through the thick ice and use a huge net to catch winter fish in the freezing waters. This special method has been listed as an intangible cultural heritage (非物质文化遗产).
Every year in December, there is a winter fishing festival, which marks the beginning of the winter fishing season. Over 20 activities are held during the festival, such as winter sports competitions, nature watching, and the selling of the first-caught fish.
None of the tourists at this year’s festival would ever imagine that Chagan Lake used to be only tens of square kilometers in size. In the past, there was little rainfall and the lake grew smaller over time. Also, overfishing is one of the main reasons.
To bring Chagan Lake’s beauty back, the government used a lot of different methods. They brought in water from the Songhua River, grew more plants, and kept the water clean. The lake now covers about 500 square kilometers, and fish numbers have returned to a normal level. Now, an increasing number of tourists flock to the lake each year to experience the ancient ice-fishing tradition.
