2 . When micro-plastics end up in farm fields, the pollution can damage plant growth. But two young researchers now report that combining fungi (真菌) with certain farm wastes can partly overcome that problem.

May Shin, 20, and Jiwon Choi, 18, met in a research design class at the Fryeburg Academy, a high school in Maine. May had desired to explore how micro-plastics might affect the ecosystem. Jiwon was crazy about plants and fungi. The young scientists cooperated to test how long-lived plastics might affect farm crops.

Scientists have shown certain fungi can aid root growth and a plant’s nutrient uptake. Those organisms are named arbuscular mycorrhizal fungi (AMF). Certain farm wastes, like straw, can provide nutrients to plants and help stabilize their roots. Such wastes are also known as mushroom substrate (基质) and people often grow mushrooms in them.

May and Jiwon planted over 2,000 scallion (大葱) seeds in pots of soil. Half the seeds got soil polluted with micro-plastics. The rest grew in plastic-free soil. The plants then were further divided into four groups. The young scientists added AMF to the soil in one group. Another group had a top layer of mushroom substrate. A third group got both treatments. The last group got none. For three weeks, the pair tracked how many scallions sprouted (发芽) in each group and measured the plants’ height once each week.

About twice as many scallions sprouted in clean soil compared to that containing plastic bits. But among plants surviving in the polluted soil, a combination of AMF and mushroom substrate helped them out. Those getting both treatments grew 5.4 centimeters per week. That was faster than either of the treatments alone or those getting none.

Jiwon and May then looked at the plant roots with a microscope. Where AMF had been added, it grew into those roots. That increased the scallion roots’ surface area, May said, which should promote their uptake of nutrients. So “I see this project as coming up with a sustainable solution for plant growth in polluted soils,” said May.

3 . Four years ago, Rome Leykin was on his way to work when he accidentally fell onto the tracks of Brooklyn's train as a subway was approaching. The incident resulted in the loss of both of his legs.

But surprisingly, with the loss of his legs, Leykin gained a new passion for racing. Before his accident, he wasn't really that athletic. He would just occasionally play basketball. But that all changed after he was introduced to hand cycling. “When I saw it, I was like, ‘Oh, this is great. You don't even need legs to use it. This is perfect.’” he said. “So, I got on it, I rode and fell in love with it right away.”

Within a few months, he completed the TD Five Boro Bike Tour, a 40-mile ride through New York City. After that, he did his first marathon in 2021. He fished that race in 2 hours and 11 minutes, placing 12th out of 38.

“I'm going to attend this year's marathon and take on challenges. My hands are on the wheel, my eyes are focused, and I think my time is going to speak for itself.” he said. He's made a significant commitment to training. He hand cycles at least 13.1 miles a couple times a week and spends a lot of time in the gym.

And he plans to keep pursuing his athlete goals. He wants to complete the Abbott Six-the world's six largest marathons. One day, he said, he'll maybe even make the Paralympics.

For those who might be following his journey, he hopes they will take some lessons from his story. “There will be ups and downs but the trend is what's important. Focus on the good,” he said. “And also, take your big problems and split them into small solutions. And then all of a sudden, your big problems turn into many small wins.”

Chinese calligraphy (书法) is an art form that    1    (involve) the skilled and deliberate use of brush and ink to create beautiful and expressive characters.

The origins of Chinese calligraphy can be traced back thousands of years to the Shang Dynasty, making it one of the     2     (old) continuous artistic traditions in the world. Its evolution is accompanied with the development of the Chinese writing system,     3     consists of thousands of characters, each with its own artistic structure and stroke order (笔顺).

Calligraphy in China    4    (regard) as one of the highest forms of artistic expression. It is not only a means of communication     5     a way to develop one’s character, discipline, and spirituality. The practice of calligraphy requires     6    (patient), concentration, and a deep understanding of the balance between empty space and solid forms.

Different styles of calligraphy have emerged throughout history, each with its own distinct characteristics and artistic conventions. The most famous    7    (style) include regular script (kaishu), running script (xingshu), cursive script (caoshu), and seal script (zhuanshu).

Chinese calligraphy has a profound influence     8     other art forms, such as     9    (paint), poetry, and seal carving. It is often considered as an important part of the Chinese traditional culture, where scholars and artists would gather in a     10    (culture) salon to appreciate and discuss calligraphic works.

8 . What if someone told you about a kind of grass as tall as the tallest trees? A grass as strong as steel? Would you believe that person? You should, for that grass is bamboo   (竹子), which has more than 1,000 uses. It is not just a material for making useful products. Young bamboo is eaten, often mixed with other vegetables.

Bamboo grows in many parts of the world. In the USA it grows in many states like Virginia and Florida. Most bamboo, however, is found in wet and warm climates, especially in Asia and on the islands of the South Pacific Ocean.

In most Asian countries, bamboo is nearly as important as rice. This unusual material is used to not only build large buildings but also make water pipes, musical instruments and paper. There are over 1,000 kinds of bamboo. No wonder the lives of nearly half the people on earth would change greatly if there were no longer any bamboo.
