1 . Humans are driving climate change. That means we can change our path.     1    , individual actions matter, too. Here are some individual actions that can make a positive impact.

    2    . First, be mindful of your meat. Cows create a lot of methane (甲烷), a significant driver of global climate change. One study found replacing beef with almost anything else for one meal a day can cut a person’s dietary carbon footprint by 48%. Then, address your food waste. Cut down on what you throw away and watch out for single-use items like coffee beans whose production produces greenhouse gases.

Extend product lifespan (寿命).     3    . Shoes, clothes, furniture and even some electronics can be repaired to extend their life and keep waste out of landfills.

Switch to electric cooking. Not only is gas-powered cooking releasing harmful chemicals into the environment, but it could be contributing to health problems for you if you’re cooking indoors.     4    .

Plant trees where you can. Trees can help control temperatures and improve air quality.     5    . Local wildlife organizations often have lists of plants with neutral (中性的) or positive impacts on local flora and fauna (动植物群).

3 . Do you remember reading an article called Kouji in middle school? In it, a kouji performer, specializing in vocal mimicry, creates lifelike performances of various sounds using just his mouth, with the stage having only a table, a block of wood on it, a chair and a fan.

Originating from ancient China, the art of kouji involves skillfully using movements of the lips, teeth, throat, and tongue to produce sounds that mimic birds, animals, and various other noises in the world. It is often combined with story-telling during performances. In 2011, kouji was recognized as a national intangible cultural heritage.

According to the IHChina website, traditional kouji is becoming endangered due to the rapid development of electronic audio. However, Cao Quyang, a 28-year-old inheritor, has found a solution by combining kouji with beatboxing, achieving a perfect combination of traditional and modern performance art.

Cao started learning kouji in 2016 when she wanted to bring something original to her B -box performance. "As a former percussionis (打击乐器演奏者), I'm sensitive to rhythm, so I integrated the kouji techniques I learned into beatboxing and created my own unique style in my area of expertise." she added. For example, when mimicking environmental sounds like wind, Cao can use her mouth to weave beatboxing into it, making the sound of the wind stronger and more rhythmic." The addition of beatboxing brings more musical expression to kouji performances, making the stories more vivid and appealing to today's young audiences." said Cao.

In addition to kouji and beatboxing, Cao can also play the Chinese drums, drum set, and piano, as well as DJ. "Innovation is not difficult for me. To me, innovation is simply expressing something that people don't understand in a way they do," said Cao, "As long as it combines tradition and modernity and allows the public to appreciate the beauty of tradition through innovation, I'm willing to do it."

We all know the characteristic     1     (feature) of a giraffe : long neck, hornlike head protuberances, spotted coat. Well, not always. A giraffe     2     (miss) spots was recently photographed     3     the first time in the wild. The unprecedented sighting, at a private game reserve in Namibia,     4     (occur) just weeks after another animal with similar coloring was born at a Tennessee zoo. No data suggest that a solid-brown coat is appearing more     5     (frequent) than in the past, but it's a surprising coincidence, says Sara Ferguson, a wildlife veterinarian and     6     (conserve) health coordinator at the Giraffe Conservation Foundation. The last     7     (report) all -brown giraffe sighting was in 1972, at a Tokyo zoo.

Genetic mutations are the likely cause,     8     the animals don't seem to be at a disadvantage, says Derek Lee,     9     biologist at Penn State University who co-authored a 2018 study     10     found some aspects of giraffe markings are passed down from mother to calf. Are the all - brown giraffes truly spotless ? Technically, Lee says, they're " one-spot- all - over giraffes."
