2 . The Silk Road is the name of different roads that long ago connected Europe, Africa and Asia. People reached these different places along these roads. Scientists believe people began to travel the Silk Road about 3000 years ago. By the time the Chinese silk trade became important in the world, the Silk Road covered almost 6500 kilometers. It spread from Rome to China, which is from the West to the Far East.
Traders travelling along the Silk Road carried silk, of course. They also carried and traded spices (香料), cloth, valuable stones and gold.
There is a famous old story along the old road. It is said that Roman soldiers travelled through central Asia. They started to live somewhere near the ancient Chinese village of Liqian. Sortie of these Romans married local Chinese women and the story of blue-eyed villages of China was started.
During its busiest period, the Silk Road allowed people from many different cultures and countries to meet each other and mix. The Silk Road allowed the sharing of valuable goods and new ideas. These included people and trading goods from the Mediterranean, Persian, Magyar, Armenian, Bactrian, Indian and Chinese areas. All these peoples travelled the Silk Road, and they shared goods, stories, languages, and cultures.
In modern times, the old Silk Road routes (路线) are still used, but now they are crossed by trains instead of camels and horses. There is even a Silk Route Museum in Jiuquan in China. It has over 35,000, objects from all along the Silk Road. In this way, China protects the history of many countries and peoples.

4 . In a world-record effort to help save a valuable sea creature, Australian scientists have released hundreds of baby seahorses into the wild. The tiny seahorses are endangered, and the scientists hope the new seahorses will help their numbers grow.
Seahorses get their name because they look a bit like horses. They aren’t great swimmers, even though they’re fish. They often use their tails to hold onto something in the water. They mostly live in warm, shallow waters around the world. They are often found in coral reefs, in beds of seagrass, and areas where rivers empty into the sea. Seahorses form an important part of the ocean’s food chain. They eat tiny sea creatures and are eaten by bigger sea animals.
Many kinds of seahorses are often threatened by the human actions. Sometimes they’re caught and sold as pets. They are also caught by accident when people are trying to catch other fish.
To begin the project, scientists collected three pregnant seahorses in January. Those seahorses were brought back to the aquarium (水族馆) in Sydney. After the babies were born, the scientists kept them there for five months, feeding the baby seahorses shrimps (小虾) to help them grow strong. Scientist Mitchell Brennan says, “They don’t have a stomach, so they have to eat constantly.”
About a month before the young seahorses were released, the scientists created eight underwater “hotels” for them. The hotels look like cages, providing a safe place for the seahorses to develop. Putting the hotels into the sea early allowed the cages to be covered with small sea life that can help provide food for the seahorses.
This is the fifth time the scientists have released seahorses into the area, and this time was a record. Around 380 seahorses were released. The researchers put tiny tags (标记) under the skin of many of the seahorses to help track them in the future.

5 . When the patient arrives, it can barely move its body. The parrot tries to spread its green wings — and fails — to fly. It is just one of dozens of rainbow lorikeets (彩虹鹦鹉) being treated for a mysterious paralyzing (瘫痪) illness. Cases of what is called lorikeet paralysis syndrome (LPS) have been increasing over the past decade, says vet Claude Lacasse. But scientists are puzzled as to what is causing it.
Lacasse has partnered with several researchers to try solving the mystery. So far, they’ve ruled out hundreds of human-made chemicals as well as various infectious diseases. Their current theory is that LPS is caused by a plant the birds are eating, something that flowers or fruits between late spring and early fall — when cases always rise.
But researchers have no idea which plant or plants might be involved, why the disease is getting worse or whether climate change is playing a role. For now, the main concern is figuring out everything the sick lorikeets are eating.
Ecologist Rachele Wilson used a technique involving testing DNA in sick birds’ droppings to match it to specific plant DNA. These data suggest the birds are feeding on more than 130 plant species, at least 30 of which are potentially poisonous. Other researchers are not just looking at plant DNA but also at bacterial and animal DNA to allow for the possibility that the birds are swallowing a poisonous insect in fruit, or a poison produced by bacteria found on a plant.
It’s possible climate change plays a role by driving rainbow lorikeets to seek out unusual food sources. Animals are broadening their hunting range and going into more traditionally uninviting areas to find food, including fruit, seeds and, strangely, even meat.
With climate change causing more extreme weather events and intensely hot summers, the need to find what’s paralyzing rainbow lorikeets — and potentially other species — is of urgent concern.
“They’re amazing birds,” Phalen says. “It’s hard to see them as sick as they are.”

6 . Almost a quarter of the UK’s sea swimmers may not swim in the ocean this year because of sewage (污水) dumping by water companies, according to a poll (民意调查). Sewage was dumped into waters near England’s most celebrated beaches for nearly 8,500 hours last year. And there were 1,504 discharges (排出) in 2022 on beaches supposed to be free from such pollution.
The poll spoke to 2,272 UK adults between 21 and 23 on July. Just over 30% said they typically went sea swimming during the summer, and of these 23% said they would not this year because of sewage dumping by water companies. More than two in five of the regular beachgoers also said they were less likely to visit the British seaside this summer because of sewage discharges.
The Department for Environment says government should allow the Environment Agency to charge unlimited fines on rule-breaking water companies. Fines are currently capped (上限) at £250,000. The Department for Environment has been calling for a sewage tax on annual profits and a ban on bonuses of water company managers. “Coastal communities are at the mercy of water companies who unapologetically discharge raw sewage into popular swimming spots,” Tim Farron, the Department for Environment’s spokesperson said. “The government needs to stop letting water companies off the hook and finally ban these terrible sewage discharges and defend our tourism sector.”
A Water UK spokesperson said standards at beaches had greatly improved since the 1990s but that the industry recognized it had been slow to deal with the harm to our seas caused by sewage overflows. “Over the next seven years, water and sewerage companies plan to spend £10bn—doubling current levels of investment—on sewage treatment,” they said. “As part of this, bathing waters will be among the first to receive funding.”

8 . The Elephant Project is a purpose-driven company which tries to protect and recover the world’s elephant population.
This all-female organization began when founder Kristian McKean saw the inhumane(不人道的)treatment of elephants in Thailand, and again back in the United States with circus animals. Determined to find a way to support elephant causes, Kristina used her product development background to design adorable, huggable elephant dolls she named Kiki and Tembo.
Children and many adults are drawn to the stuffed animals. These elephants come with fun educational materials to spread the word about the dangerous world elephants live in.
Meanwhile, the company’s mission is clear and supported by its donations to organizations that care for elephants in need. In fact, 100% of the profit from each sail of Kiki and Tembo goes to supplies and aid for abused and injured elephants through The Sheldrick Wildlife Trust in Kenya and The Elephant Nature Park in Thailand. The Elephant Project also contributes to efforts to end illegal elephant hunting.
Of course, even without the notable mission of the company, these little dolls are gift able to children. Kiki, whose name means “new life”, wears a little pink outfit(套装). Meanwhile, Tembo, meaning “elephant” in Swahili, wears a green outfit.
A new release features Baby Chaba, a baby elephant named after a real baby who was rescued alongside her mother by Lek Chailert, the founder of the The Elephant Nature Park, in August 2021.The purchase comes with Baby Chaba and a book that explains her story.
The Elephant Project website shows a list of elephants that have already benefited from the company, with a bit of history about each elephant’s situation and progress. The mission has now also spread to support g the rescue and rehabilitation (修复) of big cats who like elephants and other wildlife, suffer from n humane treatment, competition for resources and loss of habitat.

10 . Electric car are dirty. In fact, not only are they dirty, they might even be dirtier than their gasoline (汽油) powered cousins.
People in California love to talk about “zero-emissions (无污染的) vehicles,” but people in California seem to be clueless about where electricity comes from. Power plants mostly use fire to make it. Aside from the new folks who have their roofs covered with solar cells, we get our electricity from generators. Generators are fueled by something—usually coal, oil, but also by heat generated in nuclear power plants. There are a few wind farms and geothermal (地热的) plants as well, but by far we get electricity mainly by burning something.
In other words, those “zero-emissions” cars are likely coal-burning cars. It’s just because the coal is burned somewhere else that it looks clean. It is not. It is as if the California Green are covering their eyes—“If I can’t see it, it’s not happening”. Gasoline is an unbelievably efficient way to power a vehicle, a gallon of gas has a lot of energy in it. But when you take that gas (or another fuel) and first use it to make electricity, you waste a nice part of that energy, mostly in the form of wasted heat-at the generator, through the transmission (传送) lines, etc.
A gallon of gas may drive your car 25 miles. But the electricity you get from that gallon of gas won’t get you nearly as far-so electric cars burn more fuel than gas-powered ones. If our electricity came mostly from nukes(核能)or geothermal, or gyro, or solar, or wind, then an electric car truly would be clean. But for political, technical, and economic reasons, we don’t use much of those energy sources.
In addition, electric cars’ batteries which are poisonous for a long time will eventually end up in a landfill. And finally, when car are the polluters, the pollution is spread across all the roads. When it is a power plant, though, all the junk is in one place. Nature is very good at cleaning up, but it takes a lot longer when all the garbage is in one spot.
