6 . The Power of Poetry
People are suffering from depression and anxiety now more than ever. To help case the pain, they are turning to new approaches and, believe it or not, poetry is one of them.
It’s common sense that reading fiction can increase empathy (同理心).
Poetry can be a form of comfort. By reading poetry, we can get the escapism we long for, transporting us out of our own world and into someone else’s.
It can be a shared experience. Poems are often quite emotional in nature.
To put it lightly, life is tough, but it’s important to remember that we’re not alone. The next time you’re feeling hopeless, try diving into the works of a poet.
| A．However, how does it work? |
| B．But what’s so special about poetry? |
| C．As the saying goes, misery loves company. |
| D．Poetry can also be a platform for change and advocacy. |
| E．You might be inspired to write some poetry of your own. |
| F．Chances are that you will heat the love songs of the poet. |
| G．The repetition and rhyme found in it can relieve our pain. |
7 . Researchers say two-way communication is possible with people who are asleep and dreaming, specifically, with people who are lucid dreaming — that is, dreaming while being aware you’re dreaming.
Lucid dreaming is not common. So to study it, researchers looked for people who had experience with it and also trained people to try to make lucid dreaming more likely. Before the people taking part in the program went to sleep, they were also trained on how to communicate their answers. Special sensors (传感器) measured people’s eye movements or experts would judge their facial movements. For example, a typical question would be to ask what is 8 minus 6. A 19-year-old American man was able to respond by moving his eyes left-right, left-right — two times — to signal “2.” Researchers asked the question again, and he moved his eyes the same way two times again.
Out of the 158 trials among 36 participants, about 18% of the time, they were able to give correct answers. In another 18%, it wasn’t clear whether participants were responding or not. They were wrong 3% of the time. Most often, 61%, participants didn’t respond at all.
The researchers write that their findings offer “new opportunities for gaining real-time information about dreaming, and for changing the process of a dream”. And if more reliable communication methods can be worked out, it could help people with creative activities and ideas.
“People often use lucid dreaming or dreaming for a kind of artistic, creative inspiration,” says Karen Konkoly, a Ph.D. student at Northwestern University. “But in that dream state, your resources so far are only the ones that you have in the dream.” So with the help of a person awake, Konkoly says it could be possible to “combine those logical advantages of wake with the creative advantages of dreams and maybe have some more applications.”

8 . The Silk Road is arguably the most famous long-distance trade route of the ancient world. This passage connected Europe in the West with China in the East, and allowed the exchange of goods, technology, and ideas between the two civilizations. Although merchants could make huge profits travelling the road, it was not without risk.
The main Silk Road started in Chang’an (known today as Xi’an), the early Han capital. Travelers commencing their journey from this city could take a northern route that would take them across China’s northwestern provinces. After this, they would face the Gobi Desert, arguably the greatest danger of the Silk Road.
The Gobi Desert, the largest desert in Asia, consists mainly of rocky, hard earth. This feature made it easier for traders to travel across, compared to sandy deserts like the neighboring Taklamakan Desert. Like other deserts, the Gobi Desert is dry and hot, and therefore the biggest challenge travelers faced was obtaining enough water for themselves as well as for their camels.
So, rest stops were created along the route, allowing travelers to rest, eat and drink. These places also promoted the exchange of goods, and even ideas, amongst the travelers who stopped there. Usually, the rest stops were placed within a day’s journey of each other. In this way, travelers could avoid spending too much time in the desert, which would make them targets for robbers, another danger of the Silk Road.
Once through the Gobi Desert, travelers would continue their journey into Iran, Turkey, and finally Europe. While this part of the journey may have been less dangerous, it is not entirely without its perils (风险).

10 . Concerns about health, animals and the environment are leading more people to remove meat from their diet. Plant-based meat alternatives(替代物) increasingly appear in supermarkets and restaurants. But what some people call clean meat—meat grown from cells in a laboratory—is still an idea that is just beginning.
More than 24 companies are testing lab-grown fish, beef and chicken. These business hope to enter the alternative meat market, which could be worth $140 billion by 2029. One of the companies, Shiok Meats, grows its product by taking shrimp(虾) cells and keeping them at a fixed temperature. They are then given nutrients(养分) in a solution. The cells become meat in four to six weeks.
This lab-grown meat’s price is high. One kilogram of it now costs $5,000, said Shiok Meats’ chief executive Sandhya Sriram. At that cost, a single pork and shrimp dumpling could be as much as $300. Sriram, a vegetarian, hopes to cut the cost to $50 for one kilogram by the end of this year. “We are looking at next year, so we might be the first ever company to launch a cell-based meat product in the world,” Sriram said. “Shiok Meats still needs approval from the city’s food regulator, and that matters the most at present.”
Although people increasingly demand meat alternatives, cell - based meat companies still face resistance to their products. In Singapore, some people said they would give lab-grown meat a second thought. “I may not exactly dare to eat it, but I do find the idea appealing because the animals in the oceans are declining,” said 60-year- old Pet Loh, while she shopped for shrimps in a Singapore market.
Any alternative wav of making animal protein without harming the environment is positive, said Paul Teng, a specialist in agriculture technology at Nanyang Technological University. But, he added, more studies are needed to understand any negative result of making cellular protein.
