2 . A roadside system that detects if a mobile phone is in use in a passing vehicle is being tested in the UK first. Despite being unable to tell whether the driver is using the phone, it is hoped that it will act as a warning to people who make calls behind the wheel. The technology picks up the phone signal in the vehicle and activates(激活) a roadside warning sign of a mobile phone with a red line through it.

The system can’t tell the difference between a driver and a passenger on a bus, but to some degree it can warn drivers that they can be detected using their phones. Using a directional antenna(天线)，the detector picks up radio waves produced by a phone handset , and measures the signal strength and length of them. When a signal is detected of duration(持续时间) long enough and signal strength strong enough to set off the system， the detector activates the warning sign. The detector is able to distinguish Bluetooth connections or hands- free devices which, when picked up，will prevent the activation.

While this new system is no replacement for a police officer catching someone in the act， it could be enough to make some drivers think twice- and that has to be a positive step forward. However, just as technology has enabled the problem of drivers using mobile phones illegally, it can also be a big part of the solution in getting people to stop. Statistics from the devices will be shared with Norfolk Police， the county council said. The council said that enabling the system to record specific number plates could be a“future development”.

Using a mobile phone at the wheel is one of the four road crimes which can have horrible consequences if it causes a deadly or serious car crash. Law enforcement(执行) technology has been falling behind for a decade and not made any easier by motor producers that encourage users to plug in their phones even before driving.

6 . Masks that helped save lives are proving a deadly danger for wildlife, with birds and sea creatures trapped in the shocking number of thrown-away facial coverings. Single-use masks have been found around pavements, waterways and beaches worldwide. Worn once, the thin protective materials can take hundreds of years to decompose. “Face masks aren't going away any time soon—but when we throw them away, these items can harm the environment and the animals,” Ashley Fruno of animal rights group PETA said.

In Britain, a gull was rescued by the RSPCA after its legs became tangled in the straps of a mask for up to a week. The animal welfare charity took it to a wildlife hospital for treatment before its release.

The biggest impact may be in the water. More than 1.5 billion masks made their way into the world's oceans last year, accounting for around 6,200 extra tonnes of ocean plastic pollution, according to environmental group Oceans Asia.

Conservationists in Brazil found one mask inside the stomach of a penguin after its body was washed up on a beach, while a dead pufferfish was discovered caught inside another off the coast of Miami. French campaigners found a dead crab trapped in a mask near the Mediterranean. Masks and gloves are “particularly problematic” for sea creatures, says George Leonard, chief scientist from NGO Ocean Conservancy. “When those plastics break down in the environment, they then enter the food chain and impact entire ecosystems.” he added.

There has been a shift towards greater use of reusable cloth masks as the pandemic has worn on, but many are still using the lighter single-use varieties. Campaigners have urged people to bin them properly and cut the straps to reduce the risk of animals becoming trapped. Oceans Asia has also called on governments to increase fines for littering and encourage the use of washable masks.

7 . Daphne Soares, a biologist, makes an amazing discovery about alligators. The first time she got really close to an alligator (短吻鳄) was when she was helping to bold down an eight-foot American alligator. It was then that she noticed is face was covered with little black spots. This led to the discovery of the little black dots.

She started her study of the black dots. When she read the books and scientific journals, she learned that people had noticed the dots, but no one really knew what the dots were for.

To find out the secret she placed electrodes (电极) on nerves coming from some of the dots. When the nerves fired, they sent a message to the brain and created a tiny electric current. Just then she heard a small sound over a loudspeaker. She tired to see if the dots acted like eyes and temperature sensors, but nothing worked.

One day she was careless with dropping a tool into an alligator’s tank. When she put her hand in the tank to get the tool out, she made small waves in the water. When they reached the alligator’s face, she heard a noise over the speaker. She then realized that the dots must be sensitive to the changes in pressure when hit by waves of water.

After that, she is now studying blind cavefish. She is trying to learn whether they are blind from birth or lose their sight as they grow up. She is also doing more research on crocodilians (鳄目). She wants to find out how the genes of alligators with pressure sensors only on their faces differ from the genes of crocodilians that have pressure sensors all over their body.

8 . Li Bai is regarded as the greatest romantic poet of the Tang Dynasty and a representative of the High Tang culture, combination of realistic Northern culture represented by Confucian philosophy and romantic Southern culture represented by Taoist philosophy. But he could neither realize his Confucian ideal to serve the country nor find spiritual freedom in Taoism, so he could only chant poetry and drink wine to drown his sorrow as described by Du Fu in Eight Immortal Drinkers. Here we see the tragedy of a genuine staying lonely on earth like an angel fallen from Heaven. His poetry is marked by male greatness in the Waterfall in Mount Lu Viewed from Afar, in which we see the mountain cloud from down below and the Silver River, Chinese name for the Milky Way, fall from on high, and heaven and earth seem to merge into one, that is the Chinese way of communion with nature. In his poetry, we can find his love of nature, of freedom, of the people, of his friends, in short, of truth, good and beauty.

Li Bai is best known for the extraordinary imagination and striking Taoist imagery in his poetry, as well as for his great love for liquor. Like Du Fu,   he spent much of his life travelling, although in his case it was because his wealth allowed him to, rather than because his poverty forced him. He is said to have drowned in the Yangtze River, having fallen from his boat while drunkenly trying to embrace the reflection of the moon.

10 . This was the first real task I received in my new school. It seemed simple: go on the Internet and find information about a man named George Washington. As I searched the name, I found that there were two famous people having the same name who looked completely different! One invented hundreds of uses for peanuts(花生), while the other led some sort of army across America. I stared at the screen, wondering which one my teacher meant. I called my grandfather for a golden piece of advice; let the coin decide. I flipped(掷) a coin and Ah! Tails (背面)! My report would be about the great man who invented peanut butter, George Washington Carver.

Weeks later, I stood in front of the classroom and proudly read my homework. But things started to get strange. I looked around the room, only to find my classmates with big smiles on their faces and tears in their eyes and my stone-faced teacher. I was completely lost. “What could be causing everyone to act this way?”

Oh well, I dropped the paper and sat down at my desk, burning to find out what I had done wrong. As a classmate began his report, it all became clear, “My report is on George Washington, the man who started the American War of Independence.” The whole world became quiet! How could I know that my teacher meant that George Washington?

Of course, my subject result was awful. Sad but fearless, I decided to turn this around. I talked to the headmaster Miss Lancelot, but she said firmly: No re-dos; no new score. I felt that it was not fair, and I believed I deserved a second chance. So I threw myself heartily into my work for the rest of the school year. Ten months later, I sat in the headmaster’s office again, but this time a completely different conversation. I smiled and flashed back to the terrible moment at the beginning of the year as the headmaster told me I was good enough to skip(跳过) the 6th grade and started the 7th grade next term.
