— Oh, I watched it. Several ____ drones lit up the night with stunning light shows.
This summer, my family and I visited Bama in Guangxi, a place famously known as the"longevity village"(长寿村). Many elders there 1 to be over 100 years old. Knowing that the average human lifespan (寿命) in China is around 78 years,I was 2 about this amazing place and wanted to find out what makes it so special.
Upon arrival the first thing I noticed was the fresh and clean air. Local people say there is more oxygen there due to the 3 population and the richness of plants. Bama was cool and a bit humid 4 it was mid-August, making it perfect for a walk.
On the second day, we 5 Bama's famous"magnetic cave"(磁洞). It is believed that the strong magnetic field inside can help people live longer and treat various diseases. Although there is no scientific practice, I felt 6 after spending some time inside.
For meals, we had soup dishes that, according to the locals, could increase appetite(食欲) and make people 7 . The soup was just a mix of tofu, lettuce, and water, but I had two bowls. I didn't notice any increase in intelligence, but I did eat more than usual after having the soup. I also observed that the villagers 8 ate meat and mostly ate vegetables and tofu. Each dish was so delicious that I couldn't wait for it to 9 , and by the end of the meal, I was sweating.
After 10 Bama myself, I believe that the environment and eating habits are the key reasons why this village is so special and helps people live long lives.
Many of us get to see wild animals only when we visit zoos. These special places let us observe amazing creatures, from big lions and tigers to tiny lizards, and learn about them. It's both fun and educational, but do animals really like living in zoos?
In the past, people could only see dead animals shown in museums. Later, explorers caught live animals and showed them off in wildlife park. Back then, animal welfare(福利) wasn't important. But today's zoos have changed a lot. They' ve made bigger enclosures(围地), taken away bars, and tried to copy animals' natural homes.
Some people think keeping animals in cages for our entertainment is cruel. But zoos say they help wildlife by teaching us about conservation. In the UK, zoos must educate the public because of the Zoo Licensing Act passed in 1981. Good zoos also support protecting programs, which help protect wildlife in their natural homes.
Zoos today state they protect endangered animals because of climate change. Robert Young, an expert at Salford University, says many species would be gone without zoos. Some zoos have breeding(繁殖) programs to save animals from disappearance. For example, Chester Zoo in the UK brought back a rare fish by breeding and releasing them into their local river.
Even though people still argue about zoos, new ways to see wildlife are being developed, like virtual reality(虚拟现实). Imagine walking through a herd of elephants in the Serengeti— it might happen sooner than you think. As technology develops, new ways to connect with nature may become more popular.
Two Canadian teenagers, Faiz and Leo, have been taking on a series of wonderful challenges. Their most recent achievement was following the Lake Ontario coastline for 73 kilometers, walking from Toronto to Hamilton, Canada, in about 18 hours.
"We enjoy trying new things that are good for our bodies and minds. We like to overcome challenges like these. And we feel going on a long walk seems to be the purest form of challenge that you can have," Leo said.
With very little preparation, the two 16-year-olds began their journey at 6 am, starting in darkness and finishing before midnight. They took several breaks, stopping at benches with nice views along the way.
On their walk, one of the interesting things they came across was a cargo ship (货船) which was no longer used. "You' d be surprised by the things that you don't see when you' re driving and that you will see when you' re taking your time walking," said Leo.
However, the journey was not only a trial (考验) for bodies but also an important test of minds. There were moments of loneliness for the pair, requiring them to support each other along the way.
Around 70 km into the walk, they ran into a person on a bridge who appeared to be experiencing something painful.
"I wasn't sure what was going to happen me and Leo, we tried to talk him out of it and ended up calling the police, and the situation was eased and everyone was OK," Faiz said.
The walk is now long over but Faiz and Leo are not done challenging themselves, with plans to start a two-day 100 km walk in the near future.
Asking ChatGPT 4, an AI chatbot, to write a 100-word email might take just a few seconds. But have you ever wondered about the environmental influence of this technology? The rapid growth of AI is raising concerns. Many people realize that the tool comes with hidden costs, especially the large amount of energy used by digital services.
One of the main problems is the"water footprint", the total water the AI chatbot uses in its lifetime.AI depends on data(数据) centers, which house servers that store and manage data. Once turned on, the servers produce heat. To cool them down, engineers use pipes to bring in cold water from cooling towers to take away the heat.
Data centers operate around the clock, making them very"thirsty". According to The Washington Post, ChatGPT 4 needs about 519 milliliters of water, or a little more than a bottle for every 100-word email. Each year in the US, ChatGPT 4 uses over 435 million liters of water just for emails - enough to support a regular US family for 1,050 years.
Meanwhile, data centers are"hungry" for electricity. Writing a 100-word email requires 0.14 kilowatt-hours of electricity, which can power 14 light bulbs for one hour. Yearly, ChatGPT 4 uses up over 120,000 megawatt-hours(兆瓦时) of power just to help write emails. This is enough to support all homes in Washington DC for 20 days.
Now, businesses are looking for different ways to make AI more environmentally friendly. Microsoft uses cold metal plates with cold water to cool machines. Clean energy is also helpful; for example, Tencent's data center is powered by solar energy. Another company, Google, uses developed cooling systems that rely on outside air to cut down cooling needs.
Getting a present is super exciting-imagine opening a box to find something cool and just for you. Now, imagine if you could get the same feeling when you go shopping for yourself.
Mystery boxes are not a new idea. Inside, you' ll find lots of different things, all sold cheaper than what they' re worth together. The key thing is that customers don't know what's in the box before they buy. There are all kinds of mystery boxes: fashion boxes, food boxes and so on.
In addition, they let you try new things you might not have. For example,a seasonal vegetable box could teach you to cook new meals. The total price of what's inside is usually more than what you paid. Stores like them too because they can sell unwanted things and still make a profit.
When you buy a mystery box, you don't know what you' ll get! Sometimes, you might not like what's inside. Someone might even put in cheap things that' re not worth the box's price.
While mystery boxes can be fun and save money, there's always a chance you might not like what you get. It's important to be prepared for both good and bad surprises. Remember to shop wisely and enjoy the excitement of opening a mystery box!
A. They can also possibly offer great savings.
B. However, there is a key disadvantage to mystery boxes.
C That's the feeling that mystery boxes hope to provide.
D The pleasant surprise is not the only attraction of mystery boxes.
E. They were around in big stores in Japan in the early 20th century.
F. The idea of mystery boxes has developed greatly over time.
Have you ever heard of the phrase"city bu city"? This fun phrase, which means something like"is it a city or not?", (create) by a foreign blogger named Baobaoxiong during his visit to the Great Wall in Beijing in June 2024. It's a way to ask if a place has the ( fashion) atmosphere of a big city.
Many foreigners are posting ( they) China travel stories on video blogs, or vlogs. One reason for this trend is the visa-free transit(过境) policy. In 2013, this policy started in seven big cities Beijing and Shanghai, so travelers could stay for 72 hours without a visa. Now, the policy allows travelers from 54 countries ( explore) China for up to six days without a visa if they have a valid (有效的) ticket to leave within 72 or even 144 hours.
An Irish blogger on his channel said, "Many people in the West think of China in negative way. That's why we wanted to come here and see it s really like." He visited Chengdu and was ( surprise) by how good, beautiful, and modern it was, which was totally different from his expectations.
Seeing is ( true) believing. This policy not only makes visiting China ( easy) but also encourages foreign visitors to experience everyday life in China.
