Broadcom MASTERS® (Math, Applied Science, Technology and Engineering for Rising Stars), a program of Society for Science & the Public, is a national science competition for middle school students. Here are four award winners this year.
Rachel Bergey, 14, in Harleysville, Pennsylvania, won the $10,000 Lemelson Award for Invention, awarded by The Lemelson Foundation to a young inventor creating promising solutions to real-world problems. Rachel developed a trap made of tinfoil (锡纸) and netting for the Spotted Lanternflfly (斑点灯笼蝇), a species causing damage to trees in Pennsylvania.
Alaina Gassler, 14, in West Grove, Pennsylvania, won the $25,000 Samueli Foundation Prize for her project reducing blind spots in cars. She designed a system that can display anything that might block the driver's line of sight. Alaina was inspired to create her device after seeing her mother struggle with blind spots in their family automobile.
Sidor Clare, 14, in Sandy, Utah, won the $10,000 Marconi/Samueli Award for Innovation, an honor made possible by Samueli's generous donation of his 2012 Marconi Society Prize Award.
Sidor developed bricks that could one day be made on Mars, so that humans would not be required to bring building materials in order to build there.
Alexis MacAvoy, 14, in Hillsborough, California, won the $10,000 Robert Wood Johnson Foundation Award for Health Advancement, recognizing her hard work and excellent performance in health-related fields. Alexis designed a water filter (过滤器) using carbon to remove heavy metals from water.
The winners were selected by a group of distinguished scientists, engineers and educators. Each winner's school will receive $1,000 from Broadcom MASTERS® to benefit their science programs.
There you are in your favorite clothing store. You don't really need to buy anything, but everything is so cheap and stylish. Before you know it, you leave the store with bags and bags of new clothes.
On the surface, this doesn't seem so bad. However, there are a lot of hidden costs behind the cheap price put forward by fast fashion brands. To put it simply, the fashion industry is terrible for the planet. Not only does it use up a lot of resources, but it also heavily pollutes the environment with chemicals, microplastics and unwanted waste.
Fashion is one of the least sustainable(可持续发展的) industries on the planet, commented Michael Stanley-Jones, a program management officer with the United Nations Environment Program.
"We've all become our own waste managers, hoarding fashion waste in our closets," he noted. It doesn't just take up space in our closets, though. It also ends up in wasteyard, too. In fact, three out of every five garments end up either being burned or sent to wasteyards.
But, thankfully, the fashion trend(趋势) tides are changing.
"People are increasingly examining their own consumption(消费) and what changes they can make to become sustainable," Jane Fellner, founder and CEO of sustainable fashion retailer Loopster, old the Guardian.
In particular, with its typically lower prices and rare fashion finds, shopping secondhand has become an increasingly popular and eco-friendly choice.
According to online reseller ThredUp, the secondhand market is predicted to reach $80 billion about 518 billion yuan by 2029. And, although fast fashion will continue to grow 20 percent over the next 10 years, secondhand fashion is expected to grow an unbelievable 185 percent in that same amount of time.
Fellner continued, "Secondhand has become more socially acceptable and, for some, cool. The act of saving is now common on TikTok."
Today was my first day at senior high and it was hard. In high school you have 4 minutes to get to your next class. My high school is very big and those 4 minutes to go from one class to another really isn't a lot of time. Today I had to go from one end of the building to the other to get from science class to math class. I wanted to go to my locker first and leave my science book there, but that took time. I was worried about being late, and I was. The math teacher said, "Just be on time tomorrow, or you'll have detention（放学后留校）"
After math, I went to art class. I like my art class a lot because I get to create things. The teacher there showed us how to make portraits（肖像）. He explained, "A portrait is a way of communicating with a person. It does not just show how the person looks but what is important to understand the person." We just did drawings today, but I know it's going to be great. I like drawing.
I like my English class, too. I think the teacher is really supportive. Today we wrote about ourselves. The teacher said to just write what you think, and we'll pay attention to punctuation（标点）later. We could write a paragraph or a poem, and I wrote a poem about myself. I thought it was a good poem, and the teacher said I had used good images（意象）to communicate my feelings.
Lunch was very hurried. I arrived at the dining room with 12 minutes to eat. I sat with people I didn't know, and everyone was eating quickly. After lunch I signed up for a computer club. I need to learn how to use a computer well because my social studies teacher says it is the one skill you need in every class.
If we were asked exactly what we were doing a year ago, we should probably have to say that we could not remember. But if we had kept a book and had written in it an account of what we did each day, we should be able to give an answer to the question.
It is the same in history. Many things have been forgotten because we do not have any written account of them. Sometimes men did keep a record of the most important happenings in their country, but often it was destroyed by fire or in a war. Sometimes there was never any written record at all because the people of that time and place did not know how to write. For example, we know a good deal about the people who lived in China 4,000 years ago, because they could write and leave written records for those who lived after them. But we know almost nothing about the people who lived even 200 years ago in central Africa. because they had not learned to write.
Sometimes, of course, even if the people cannot write, they may know something of the past. They have heard about it from older people, and often songs and dances and stories have been made about the most important happenings, and these have been sung and acted and told for many generations, for most people are proud to tell what their fathers did in the past. This we may call "remembered history". Some of it has now been written down. It is not so exact or so valuable to us as written history is because words are much more easily changed when used again and again in speech than when copied in writing. But where there are no written records, such spoken stories are often very helpful.
Earthquakes strike without warning and are among the most destructive natural disasters. Keeping calm and proper reaction can sometimes save your life. To ride out an earthquake, remember the phrase "drop, cover, and hold on."
1 Move away from buildings, street lights, power lines, and bridges.
As soon as the ground begins shaking, try to get as far away as possible from any nearby structures. Do not seek shelter under a bridge or overpass.
2 Crouch down low in a wide open area until the shaking stops.
Once you've made your way away from nearby structures, get on your hands and knees and cover your head. See if there are any objects nearby to use as a shield (遮蔽物), such as a trash can lid.
3
As you go out after the earthquake, be careful of broken glass, rubble, downed power lines, fallen trees, and any other potential danger. Check yourself and anyone nearby for injuries. If necessary,perform first aid and call emergency services.
4 Get to higher ground if you're on the shore or near a dam.
Earth quakes can cause tsunamis, so put distance between yourself and the coast. If a shaking lasts more than 20 seconds, Get to ground that's at least 100 ft (30 m) above sea level or 2 miles (3.2 km) from the shore.
A. Don't wait for an alarm or warning to escape.
B. Watch out for danger as you observe your surroundings.
C. The most dangerous locations during an earthquake are areas immediately around buildings.
D. If none are available, cover your head and neck with your hands and arms.
E. Drop to your hands and knees under a table or desk.
F. If possible, grab a pillow, sofa cushion, or another object to cover your face and head.
G. Here are four tips helping you survive an earthquake if you are outdoors.
Have you ever wondered what the real meaning of the saying "A friend in need is a friend indeed" is? People talk about the true 1 of friendship actually without knowing what it2 . True friendship is the one in which one does not have to maintain formalities (形式) with the other.

It's Best To Just Be Yourself
There is nothing like being young and eager to meet a pretty girl. I was sixteen when it first happened. Her name was Mary; she was one grade ahead and the most beautiful girl in the entire school. I was smaller than the rest of the guys my age but had many friends. I would walk by her locker (储物柜), act cool and do just about anything to gain her attention.
Nothing worked.
I often pondered to myself, how would such a beautiful and amazing girl ever fall for a guy like me? I constantly thought that if I were a "cool guy," she would eventually have to notice. Once, I "accidentally" dropped my letter jacket by her feet, just so she would note my varsity (校队) pins一and me.
She only laughed.
Then, at a weekend gathering one evening, she was there with all of her frightening friends. I decided that this had to be it; I couldn't live with myself one second more without at least trying to talk to her. I checked my ego at the door and decided to be myself. She was alone outside for one moment, and all I can remember is that she was so incredibly beautiful it made me dizzy. I walked up to her and said, "Hi, I'm Mark. You seem really nice; can we talk? "My belly rolled with butterflies while my head rushed with anxiety.
Time stood still for a moment.
She replied, "I know who you are; you're different when your friends aren't around. "And then she smiled and said, "I'm walking up the street to meet a friend. Would you like to go? "I could hardly breathe: How could this beautiful girl ever talk to a guy like me? Needless to say, we walked and talked, and she was everything I thought she would ever be. We giggled about the world and how stupid our friends and we were.

Then, to my amazement, she gave me her phone number.
We two close friends later went on to separate world-class colleges and feelings between us faded.
