1 . In July 2021, astronauts on board the International Space Station (ISS) planted pepper seeds as part of an experiment to test which plants could be successfully grown in space. The peppers were harvested four months later, and the team celebrated with a party and taste test.
For astronauts living mostly off prepackaged foods for months at a time on the ISS, fresh and flavourful produce is welcomed. With long missions to the Moon and Mars in focus, NASA is working to find sustainable ways for astronauts to enjoy fresh foods, which will add key nutrients to their diets and improve their state of mind.
Astronauts have grown radishes, zinnias and a variety of lettuces on board the ISS before, but this is the first time they grew peppers, which posed a new challenge, reports Elizabeth Howell for Space. com.
Biologists at the Kennedy Space Centre spent two years picking the perfect pepper. They wanted to try peppers because they’re a great source of vitamins and nutrients, and they can be eaten raw or cooked. Plus, peppers are fairly low maintenance to grow.
In June, a carrier delivered supplies to the ISS along with a package of 48 pepper seeds. Astronauts on board planted the seeds in a microwave oven-sized growing container. The conditions in it—such as lighting, watering and air circulation—were controlled by a crew based at the Kennedy Space Centre. On board, the astronauts collected data and offered feedback on the flavour of the peppers.
“This is important because the food astronauts eat needs to be as good as the rest of their equipment,” LaShelle Spencer, a plant scientist at NASA, said over the summer. “To successfully send people to Mars and bring them back to Earth, we will not only require the most nutritious foods, but the best tasting ones as well.”

When the recess (课间休息) bell rang, Priya sighed and slowly stood up. At her old school, she spent recess climbing the monkey bars and sharing secrets with her friends. Now she sat in the corner of the field and watched the other kids play without her.
As she cleared her table, Priya noticed a box of sidewalk chalk sitting on the counter by the window. Then she took her usual place at the end of the recess line.
While she and her classmates filed through the halls and out into the yard, Priya thought about how she and her mother used to draw chalk patterns on the long driveway leading up to their old apartment building. The patterns were called rangoli, and they looked like stars and roses. Priya’s mother said that the drawings were to welcome guests to their home. Priya missed the early mornings she and her mother would spend drawing colourful patterns.
Priya walked over to the basketball court and sat on the hot pavement (路面). She pulled the box out of her pocket and took out a bright red piece of chalk and began drawing the rangoli patterns she loved best. She drew flowers with huge petals (花瓣) and stars with eight points.
“That’s pretty,” a voice said. She turned around and saw that Enrique, a boy in her class, was watching her. “It’s called rangoli,” she said. “They do this in India, where my parents are from.” “You know what that reminds me of?” he asked, kneeling down beside her. “The floor of my grandmother’s house in Mexico has tiles (瓷砖) that have designs like that.”
“What do you mean?” Priya asked. “Hand me a piece of chalk,” Enrique said. “I’ll show you.” Enrique sat down on the pavement and began to draw. He used green, orange, and yellow chalk to draw flowers that were more detailed than Priya’s, but still had huge, curvy (弯曲的) petals. Then he drew circles inside circles, and surrounded them with small diamonds. Priya kept drawing too.

At a young age, I repeatedly heard a sentence from my grandparents, “Honesty is the best policy.” I didn’t true understand it until I was nine, when I broke a window of our classroom after the school. As no one saw it, I hurried home and tell my family happily about my “good luck”. Therefore, my father seriously said to me, “You know our family mottos: Honesty is the best policy. You broke the window, and you should responsible for it.” The next day, I apologized for my teacher. Instead of blame me, my teacher praised myself for my honesty. All in all, be honesty, and you’ll benefit from it!

8 . Imagine you’re moving to a new country on the other side of the world. Besides the geographical and cultural changes, you will find a key difference will be the language. But will your pets notice the difference? It was a question that nagged at Laura Cuaya,a brain researcher at the Neuroethology of Communication Lab at Eötvös Loránd University in Budapest.
Cuaya set out to find the answer. She and her colleagues designed an experiment with 18 volunteer dogs—including her two Border Collies, Kun Kun and Odin—to see if they could differentiate(区分) between two languages. Kun Kun and Odín were used to hearing Spanish;the other dogs Hungarian. The dogs sat still within an MRI machine, while listening to an adaptation from the story The Little Prince. They heard one version in Spanish,and another in Hungarian.
Then the scientists analyzed the dogs’ brain activity and they found a different activity pattern for one language versus(与……相比)the other. Andics, who leads the lab where the study took place, said, “The finding suggests that dogs’ brain can differentiate between these two languages. In terms of brain imaging studies, this study is the very first one which showed that a non-human species brain can discriminate between languages. ” They also found that older dogs brains’ showed bigger differences in brain activity between the two languages,perhaps because older dogs have more experience listening to human language.
Amritha Mallikarjun, who wasn’t involved in this study but has been working on similar research about dogs and language, said, “It is a very exciting study because it shows that the ability to grasp the sounds and rhythms of a familiar language is something accessible to non-humans.”“And while this work relied on brain imaging,” Mallikarjun said, “it would be worth investigating whether dogs could differentiate between languages in behavioural studies, too.”

10 . As one of the most adventurous places to visit in South America, Patagonia deserves some serious travel time. These are my top recommendations for backpacking in Patagonia:
●Patagonia is probably the safest part of South America. I’ve hitchhiked in Chile without problems and would thoroughly recommend this as a form of transport. (Get tips on hitchhiking in South America here.)
●Car hire is also an interesting and rewarding way of seeing Patagonia, although booking in advance during high season is again recommended. I recommend using Rental Cars and suggest you check out this complete guide to planning a Patagonia road trip for essential tips and tricks.
●The shoulder seasons, October — November and March — April, are far quieter and cheaper for backpacking in Patagonia. Accommodation and agencies in some towns are sometimes not running in October or April though.
●Bus schedules vary depending on the season and change year-to-year. Always visit the bus station when you get to a new place to confirm timings and buy tickets for the next leg of your journey. It’s also important to plan additional days into your Patagonia backpacking trip in case you can’t travel on the day you had initially intended. For more information about this subject, check out this detailed guide about getting to Patagonia.
●Self-catering is by far the best way of keeping costs down on these Patagonia backpacking trips. Where possible, I’ve highlighted the best places to stock up on food. I’ve also written in more detail about visiting Patagonia on a budget.
●However, crossing the border between Argentina and Chile, you cannot take fresh fruit, vegetables, cheese or meat. It will be confiscated and if you don’t own up to it (particularly when heading into Chile), you may be fined.
1. Which means of transportation is strongly recommended to Patagonia?A.Taking a taxi. | B.Going hitchhiking. |
