Facial recognition technology(人脸识别技术）is widely used today. For example, police use it to search for bad guys. It's also used to unlock phones or doors.
Now, a similar technology, known as facial detection(探测), is entering a new field: the business of advertising(广告).
Such systems are going through tests in a small number of stores. One facial detection system can judge a person's "happiness" or "fear" level. That helps businesses see how people feel as they look at products or advertisements in the store. Another system can detect whether someone is wearing eyeglasses. If so, stores can send advertisements for new glasses to him.
Facial detection technology is also placed inside some large advertising boards. Cameras in those boards can detect information like people's ages and five levels of feelings——from "very happy" to "very unhappy".
Supporters of the technology say it could improve buyers' experience by showing products they might like or by offering them products at lower prices.
Some are against the idea of using such systems. Pam Dixon, the head of a privacy(隐私)group, is one of them. She thinks ▲ . For example, a business could raise the price of a product according to a person's age and feelings.
However, one store testing the technology explained they wouldn't store people's information like names or ages. And the advertising board system maker said it didn't keep any personal information or record any videos.

【推荐3】One day, a businessman called Guo from Fujian province received a WeChat video call from a “friend” who asked him to transfer money. After verifying (验证) the face and the voice of his “friend” with a video call, he transferred money.
It turned out to be a fraud (诈骗), however. The scammer (诈骗者) used artificial intelligence (AI) to make a person look and sound like Guo’s real-life friend. Guo was scammed out of 4.3 million yuan in only 10 minutes.
The case has raised heated discussions on AI fraud. In today’s world of AI, voices, images and videos are all likely to be deeply synthesized (合成). And some people use it for criminal purposes. People who are not aware of scammers, such as children and seniors, are especially in danger of such high-tech fraud.
AI fraud is harder for people to identify. People have to be more aware of personal information protection. Don’t be so quick to give out images of faces and fingerprints to strangers.
Teenagers should particularly be careful when using social media accounts and logging in (登录) to video games to prevent their private information from being stolen.
The government is taking action to stop cases of AI fraud. In November 2022, it made clear existing bans (现行的禁令) on the generation and replacement of human faces, as well as on the creating and copying of human voices.

【推荐3】China sent a satellite on Oct 24 to carry out technological tests for space debris management. The satellite is going to use technologies to reduce space debris.
Since the beginning of the space age in the 1950s, thousands of rockets and satellites have gone to space. There are more than 500,000 pieces of debris around the Earth. Although your chance of getting hit is extremely small, we are still facing an ever-increasing risk of space junk.
More than 27,000 pieces of debris, or “space junk”, are tracked in space, according to NASA. Much more debris is too small to be tracked but large enough to threaten human spaceflight and robotic tasks. Since a piece of debris can move like a speeding bullet, getting hit by these tiny pieces often leaves huge holes in many satellites, telescopes and other objects around our planet.
Space junk is also a huge danger to spacemen. “This is particularly important. Careful consideration needs to be made about the space junk before we do spacewalk exercises.” Joon Wayn Cheong, a satellite systems expert said.
Scientists are fully aware of the problem, and they are solving it in different ways.
In 2018, the UK's Survey Space Center used a net to catch space junk in an experiment. It was the first successful tryout of space cleanup technology. It included finding debris and catching it with a net and a harpoon.
Another solution is to use robotic arms. Clear Space 1, the European Space Agency’s task to remove space junk, is expected to be sent in 2025, which will use robotic arms to catch the debris, BBC Science Focus Magazine reported. It plans to locate, catch and throw debris into the atmosphere, where it will be burnt up by the strong pressure and friction of reentry into the Earth’s atmosphere.

【推荐1】I was walking home from work on a busy city street with lots of people. I wasn't looking forward to going home, because my friends were busy with their own business and weren't able to spend time lazily with me. It's then when I walked past a homeless person that I hadn't seen before. He was moving back and forth（来回的）to stay warm, and very gently asking for some change. His words for money were so quiet that I could hardly hear him.
Something made me stop, turn around and walk up to him. At the same time, some thoughts appeared in my head like, "What do you think you're doing?" "You're alone, it's dark out and you're a woman. "Before I knew what I was doing, I asked him if he had had dinner yet and if he would like to join me at a nearby restaurant. He said he hadn't eaten and he would like to. So, he walked with me a few yards to the restaurant and held the door open for me as we entered.
He asked for the smallest thing on the menu but I ordered a larger meal and I explained that the price wasn't worth worrying about. We had a good dinner and a pleasant conversation about our life like where we grew up and what kind of music we liked. During the whole time, I just tried to say the right thing and give him the respect and care everyone has. I didn't want to show that I was better than him.
I was so grateful for this experience. I may not have met my friends that evening but I met an unexpected friend and the experience changed my life. It will make me think twice in future before I complain about something I don't have.

【推荐1】More and more people like bicycling and it is no surprise. It is fun, healthy and good for the environment. Maybe that's why there are 1.4 billion bicycles and only 100 million cars on roads worldwide today. Bikes can take you almost anywhere, and there is no oil cost!
Get on a bicycle and ride around your neighborhood. You may discover something new all around you. Stopping and getting off a bike is easier than stopping and getting out of your car. You can bike to work and benefit（受益） from the enjoyable exercise without polluting the environment. You don't even have to ride all the way.
Folding（折叠）bikes work well for people who ride the train. Just fold the bike and take it with you. You can do the same on an airplane. A folding bike can be put in a suitcase. You can also take a common bike with you when you fly. But be sure to look for information by getting on airline websites. Not all airlines are bicycle-friendly to travelers.
Health Benefits of Bicycling:
（1）. It helps to prevent heart diseases.
（2）. Bicycling helps to control your weight.

【推荐2】Looking at the traffic and crowds in Guanggu Square, one of the busiest places in Wuhan, Hubei Province, Zhao Bin realized that the city had finally recovered from the pandemic (流行病，疫情).
Zhao is a food deliveryman in Wuhan. He and other local deliverymen worked day and night with no time off and often forgot about meals during the days when the COVID-19 broke out.
The virus (病毒) wouldn’t let him and the others have a rest. “People needed us,” he said.
During the pandemic, food deliverymen had searched all stores around to prepare orders because of the shortage (不足) of supplies in Wuhan. “It was the busiest time I had ever seen as a food deliveryman,” Zhao said. “It’s so tiring, but I feel what I did was valued.”
One of the biggest changes that Zhao Bin has noticed is that customers now show more respect and understanding toward food delivery workers.
“Before the pandemic, customers didn’t understand why delivery was late on rainy days.” Zhao said. “But after the pandemic, they text us to let us know it’s fine if we’re running late.”
Zhao loves taking pictures of people since he spends most of his time on the street. He said he took up photography as a hobby after working as a museum security guard. He believes no matter how heavy the daily work is, people still need dreams and hobbies. One of his wishes during the pandemic was to get a picture of people hugging on the street, he said.
And now, the dream has come true. “My beloved Wuhan is back,” he said.

【推荐3】Has anyone ever told you that eating carrots will help you see in the dark?This is just one of many incorrect beliefs you may have heard. Below, TEENS has picked out scientific explanations for three mistakes that people make about their eyes. Let’s take a look.
Can eating carrots improve your eyesight?
Carrots are rich in vitamin A, which helps the eyes to turn light into information for your brain. This allows people to see in darker places.However, eating more carrots won’t help you see better. A certain minimum amount will help, but a large number of carrots will not give you superhuman vision.
If your parents have bad eyesight, will you have bad eyesight, too?
Myopia(近视)can be passed from parents to children. A study by the American Optometric Association found that if both parents are myopic, there’s a 33 to 60 percent chance that their child will be. For children who have one parent with myopia, the chance is 23 to 40 percent, and it’s down to 6 to 15 percent for kids with non-myopic parents. So if your eyesight is bad, your children might still have good vision.
Do color blind people see the world in black and white?
Color blindness doesn’t usually mean that people see the world like an old movie. They usually can’t tell certain colors apart, especially green and red. Another commonly confused pair of colors is yellow and blue.Our eyes have cone cells(视锥细胞)that sense different wavelengths (波长)of light. If these cells don’t work properly, color blindness occurs.
There are different levels of color blindness. Some people are only color blind in low light.
However, in the most serious form of color blindness, everything is shades of gray.
1. Which can help the eyes to turn light into information for the brain?| A．vitamin A | B．vitamin B | C．vitamin C | D．vitamin D |
| A．stops the brain from seeing |
| B．doesn’t help you see better at all |
| C．will give you superhuman vision. |
| D．is good for your eyes to some degree |
| A．40-67% | B．33-60% | C．23-40% | D．6-15% |
| A．Watching movies for too long. |
| B．Getting too little exercise. |
| C．Cone cells not working properly. |
| D．Changes in the wavelength of light. |
| A．To offer some advice on protecting your eyes. |
| B．To clear up some misunderstandings about our eyes. |
| C．To provide help for improving your vision. |
| D．To explain how bad eyesight and color blindness form. |
