Last Friday morning, hardly had I reached school while my attention was caught by a big poster on the notice board, saying that it would be the World Earth Day in a few of days.
Responding active to this, my classmates set to work immediately. In the afternoon, we brought to school what they thought to be of little value. Use scissors and paste, we made shopping bag and artworks out of them. After school, we went to the local community and launched a campaign, giving up what we had made and calling on people to make best of what they thought to be useless. Meanwhile, we hold a lecture in the community to raise people' s awareness of protecting the earth. We had a busy but meaning time.

If I could turn the clock back, I would apologize to Miss Wang for my rudeness or offensiveness. Miss Wang teaches us Chinese. She was pretty open-hearted and kindly. You could imagine a smiled young lady standing in the front of a group of troublemaking teens. One day, I asked Miss Wang several personal and rude question in class. She didn’t reply. Instead, she gave me a serious look. I thought her silence as an insult. After that unhappy experience I didn’t attend his classes any more. Missing her classes are a mistake and I feel very sorry. Every now and then this unforgettable memory appears vivid in my mind and I hope do something to make her feel better.

Getting sunburned from the Ultraviolet rays (UV,紫外线), no matter what your age is, is a risk factor for skin cancer.
Use sunscreen
Only about 19 percent of older men and 32 percent of older women report regularly using sunscreen, according to a 2019 study. But everyone should apply it to exposed skin whenever they’ll be outside, even on cloudy days. While the best sunscreen is one that you’ll use continually, our testing has found that some products perform better than others, even if they’re both marked with the same SPF. Members can find our full ratings at CR. org/sunscreen.
Attend to tricky spots
Don’t forget your ears, the tops of your feet, the backs of your hands, and the back of your neck.
Put sunscreen on 15 minutes before you go outside. Be sure to apply enough—try to use 1 teaspoon for each exposed body part. Reapply every 2 hours and after swimming or sweating.
Double your protection
Get the right sunglasses
You might find it challenging to apply sunscreen very close to your eyes, but these spots are likely to be burned, too.
A.Apply it correctly |
B.Apply it thoroughly |
C.No sunscreen perfectly blocks the sun’s rays |
D.Plus, UV rays can damage the tender parts of your eyes |
E.You can enjoy those bright summer days without getting burned |
F.Protecting yourself from the sun’s UV rays should be a lifelong habit |
G.The experts recommend a broad-range, water-resistant sunscreen of at least 30 SPF |
Supermassive black holes all over the universe are merging (合并), a fate that will eventually come for the black hole at the center of our galaxy (银河系). These magic universal structures at the heart of nearly every galaxy consume light and matter and are impossible to see with traditional telescopes. But now, for the first time, astrophysicists have gathered knowledge directly from these huge universal structures, in the form of gravitational waves that move around through space and time.
Essential to these findings is the detection of complicated gravitational waves, and understanding how they are produced. Any object with mass that is moving causes these waves—invisible bending in time and space that were first theorized by Albert Einstein in 1916 but not detected until roughly 100 years later. In 2015, scientists used the ground-based Laser Interferometer Gravitational Wave Observatory to detect how short, high-frequency gravitational waves from one merger between less massive black holes move around the Earth by less than the width of a single subatomic particle (亚原子微粒).
The findings help confirm what will one day happen to the supermassive black hole at our galaxy’s center known as Sagittarius A, as it crashes into the black hole at the heart of the Andromeda galaxy. “The Milky Way galaxy is on a crash course with the Andromeda galaxy, and in about 4.5 billion years, the two galaxies are set to merge, said Joseph Simon, a member of Nanograv. That merger, he said, will eventually result in the black hole at the center of Andromeda and Sagittarius A sinking into the center of the newly combined galaxy.
“Before now, we didn’t even know if supermassive black holes merged, and now we have evidence that hundreds of thousands of them are merging, said Chiara Mingarelli, another member of Nanograv.
If scientists understand more about the history of the merging supermassive black holes, it could help know how they form in the first place, said Masha Baryakhtar, a physicist who wasn’t involved in the research.

Though trees cannot speak verbally, Evan Luchkow, a 32-year-old Canadian filmmaker, made ancient tea trees the protagonists (主角) in his latest film, The Tree Listens, allowing them to “tell” their story about interacting with the locals in Chashu Village, Southwest China’s Chongqing.
When the Canadian stepped into the village, surprises kept coming. The luxuriant local tea trees are so tall that people need ladders to pick their leaves. The harmonious coexistence of people and nature in the village also struck him. “In Canada, the preservation of nature sometimes keeps people separated from it. On our way into this village, I saw lots of houses cradled by these mountains, which was truly surprising, says Luchkow, adding that the view was just like a postcard.
Soon he was able to set the tone for the filming, which depicts a silent dialogue between trees and people. For thousands of years, from generation to generation, the tea trees have been receiving people’s care and protection. “I think if the trees could speak, they might want to deliver their gratitude to the villagers. That’s what I tried to express via the film,” says the director.
In the process of documenting the tea village’s history, Luchkow found that the well-known Canadian coffee brand Tim Hortons had extended its footprint to Chongqing. Wu Ke, one of the many young locals who choose to stay in their hometown to make tea, finds himself gradually fall in love with coffee too. While local Chinese take to coffee nowadays, Luchkow’s friends back in Canada enjoy Chinese tea a lot. “The communication between tea and coffee is like the exchanges between people,” he says.

A nine-year-old boy has set a new 5km parkrun world record for his age group. Louis Robinett, a member of the Poole Runners junior athletics club, shaved 13 seconds off the previous world record, which was set in California in 2017, after he crossed the line in 17 minutes and 40 seconds.
Louis, who broke the record at the Poole parkrun in Dorset on Saturday, said, “I’m on top of the world right now. It’s a huge deal to break a world record. I couldn’t have done it without the support of my family and the team at Poole Runners.”
Louis was accompanied on the parkrun by Dion Garner, a member of his athletics club, as all under-11s in the 5km event must run within arm’s length of an adult. Garner said of Louis’s achievement, “His natural talent, combined with his dedication and spirit, is mind-blowing. He loves the sports and has really practiced a lot.” A spokesman for Poole Runners said, “With his new world record, Louis has raised the bar for young athletes everywhere. This isn’t just a win for Louis, it’s a new benchmark (标准) for youth sports, inspiring children all over the world to aim higher.”
Parkrun was started by 13 friends as a weekly event in Bushy Park, southwest London, in 2004. By 2015 more than 80,000 people were gathering in parks around the world each Saturday to participate in a parkrun. Only three years later about a quarter of a million people were taking part in parkruns each week, in 1,500 events spread across 20 countries. In comparison, 48,000 runners took part in the London Marathon this year.
