3 . For future humans to survive long periods on Mars, growing food on the planet is a must. It would be too costly and risky to rely upon rocket deliveries to meet the food needs of settlers. With this in mind, scientists are exploring ways to improve space farming.
Researchers work in a controlled greenhouse. They have identified a way that could improve crop production in simulated (模拟的) Martian soil, with different crops grown together. The method is called “intercropping”, invented by ancient Maya farmers in what is now Central America.
In their experiments, the researchers grew cherry tomatoes, peas and carrots together in small, round containers. Tomatoes grown in this way produced about double the amount of tomatoes grown alone — or “monocropped” — in the same simulated Martian soil. The tomatoes were also bigger. They flowered and matured earlier, gave more fruit per plant and had thicker stems. The amounts of peas and carrots did not increase with intercropping.
Rebeca Goncalves, an astrobiologist and lead writer of the study, said the research is the first time the intercropping technique was used in space soil, and that it was a big find — one that they could now build further research on. The crops were grown in simulated Martian regolith, a soil with no organic matter — a near-perfect physical and chemical match to real Martian soil.
The researchers added useful bacteria and nutrients. They also controlled the gases, temperature and humidity inside the greenhouse to match conditions expected in a Martian greenhouse. Intercropping involves growing plants with properties that could help each other grow. The method makes the best use of resources including water and nutrients.
The researchers said the tomato plants in intercropping may have benefited from being close to the pea plants. That is because the peas are good at turning nitrogen from the air, with the help of bacteria introduced into the soil, into an important nutrient. Overall, the tomatoes, peas and carrots grew well, though not as well as in Earth soil in the same greenhouse.

4 . There are some unusual wonders of our world places that most people haven’t heard about and probably don’t want to visit. But it’s good to take a step away from everything else we’ve known and see something new!
Library of Celsus, TürkiyeThe Library of Celsus was a public library built by Tiberius Julius Acquila in ancient Ephesus, now in modern-day Türkiye. It was built on the Mount Koressos and its construction began in 114 AD and ended in 117 AD. It is one of the best-preserved ancient buildings due to its Roman-time structures, which were built using marble, a type of hard, decorative stone.
Meteora, GreeceMeteora is a group of monasteries (修道院) in Greece located on top of tall rock pillars (柱子). Meteora contains 24 monasteries built on natural sandstone rock pillars between the 11th and 15th century AD. Meteora is one of Greece's most popular tourist destinations and has been a World Heritage Site since 1988.
Tower of Hercules, SpainThe Tower of Hercules is a Roman lighthouse built in 14 BC on the coast of Spain. You may be wondering how a place that was built much earlier than some of the other wonders of the world can still be considered a wonder today. Well, it was, once one of lighthouses in Europe. The tower has been rebuilt several times, but it still stands today.
Toruń, PolandToruń is one of the oldest cities in Poland and is the capital of the province of Kujawsko-Pomorskie. Toruń was founded by Teutonic Order in the mid-13th century as an important city on the trade route between Kraków and Gdańsk. The name “Toruń” comes from two German words — “tor” means gate or tower and “tun” means settlement; therefore, “Tower settlement”.

On a sunny day with no clouds, Sally sat on a chair in the garden, hemming (缝边) a handkerchief. All of a sudden, there came a little ant. It was in such a hurry. Finally it ran across the small stone table and stopped by her side. The sewing was not done, for Sally easily got a little bit distracted by this little ant. Suddenly, she dropped her thimble (顶针) over the little ant by accident while she was looking at it.“Can it mind? But it is only such a little tiny thing,”said Sally in doubt.
Then Sally ran away, for her mother called her to have lunch, and she forgot all about the ant under the thimble and the handkerchief outside. There the little ant was, running round and round in the dark place, with little horns on its head quivering, little perfect legs bending as beautifully as those of a racehorse, and it was very scared.
If Sally had remembered the ant, she would have heard this little ant say, “I can’t get out! I can’t get out! Is there anyone out there? Can someone help me out?” But unfortunately, till the bedtime, Sally failed to hear the little ant's silent calling and just went to sleep. In the midnight, there was thunder, lightning and heavy rain. The next day, when Sally woke up, she came to the garden, only to find the handkerchief was soaked (湿透的) as if somebody had been crying very much. When she was about to fetch it as soon as the sun shone, it suddenly came to her who was under the thimble. “Oh, how could I forget that little ant? I hope the little ant is doing fine,”said Sally, running with her worried face.
But when she lifted up the thimble, what came to her sight was the little tiny an t lay stiff and still. It seemed like this little poor thing was away from this world. “Oh, did it die of being under the thimble?”Sally said aloud with her trembling voice. “Why did you do that, Sally?”said her father, who was close by and looked unsatisfied.
