After graduating in 1953, Yuan Long ping worked as a researcher. He realised that larger fields were not the solution. Instead, farmers needed (boost) yields in the fields they had. How this could be done was a(challenge) question at the time. Yuan was convinced that the answer could(find) in the creation of hybrid rice. A hybrid is cross between two or more varieties of a species. One characteristic of hybrids is that they usually attain a higher yield than conventional(crop). However, whether it was possible to develop a hybrid of self-pollinating plants such as rice(be) a matter of great debate. The common(assume) then was that it could not be done.intense effort, Yuan overcame enormous technical difficulties to develop the first hybrid rice could be used for farming in 1974. This hybrid enabled farmers to expand their output (great).

"You might be out of luck, but never lose the3 to keep going. Sweat is the scent of success." Jiang recently posted that4 on We Chat. With her mother in5 health, Jiang moved to Shenzhen and became a food-delivery driver. "As long as you work hard and6 yourself well to the job, you can earn more than 10,000 yuan a month," she says. During her first year as a driver, Jiang7 the debts her family ran up for her mother's medical treatments.

Unpleasant things sometimes happen, but only heart―warming experiences remain8 in her memory. One day, a rainstorm hit the city. Jiang9 the heavy rain and sent the order to the door.10 , it had been late for a long time, and Jiang kept apologizing. But the customer didn't 11 ; instead, the customer gave Jiang some milk and cookies. "At that moment, tear swelled up in my eyes," Jiang12 .

Jiang, who is always full of13 , holds the record of making nearly 100 deliveries in a day. Also, she is a living14 in Shajing, as she knows almost every corner within her delivery area. In 2021, Jiang became the station team leader in Shajing. "The harder you work, the15 you get. I hope I can build a better life, and realize my dream here," Jiang says.

On June 15, the 100-day countdown to the Hangzhou Asian Games, the medal of the 19th Asian Games was released. The medal of the 19th Asian Games is named Shan Shui, which is another core element of the Asian Games, along with the official emblem(徽章) Tides Surging, mascots Congcong, Chenchen, Lianlian, color system Meeting the World and torch(火炬) Eternal Flame. It is an important addition to the overall aesthetic(审美) of the event.

Shan Shui is characterized by the ceremonial jade(玉) Cong in the Liangzhu Culture(5, 300BC—4, 300BC). This square jade, integrated with around medal, is truly unique and highly recognizable.

Shan Shui presents the geographical features of Hangzhou. By using prominent lines, the picture scroll of Hangzhou is outlined on the front side of the medal with misty hills on three sides and the city on one side, a rippling lake, and wavelike mountains beyond. The backside is shaped like a square seal(纪念邮戳), which means the athletes leave a beautiful mark on the Hangzhou Asian Games.

Shan Shui expresses the character of Hangzhou as the capital of ecological(生态) civilization, with natural landscape, clear water and green hills, creating in-valuable assets, casting gold and silver medals.

Shan Shui shows the sportsmanship(体育精神) of climbing the heights. Reaching the top, one will become even higher. On the way to the summit, athletes strive hard, challenge themselves, and overcome one peak after another.

The medal will be made by painting, milling, trimming and polishing, gold and silver plating(镀金) effect treatment, and protection treatment. The medal ribbon(绶带) will be hand-sewn on both sides using weave(编织) technology and environmentally friendly printing techniques. The bridge shaped buckle at the top of the ribbon highlights the Jiangnan characteristics of the water town and the bridge town. The linking method adopts the raw ear structure of the spring buck-le shaft (弹簧扣轴) to fix the ribbon inside the medal.

A robot called Bin a 48 has successfully taken a course in the philosophy of love at Notre Dame de Namur University (NDNU), in California. According to course instructor William Barry associate professor at NDNU,

Bina48 is the world's first socially advanced robot to complete a college course, an achievement he described as ""remarkable." The robot took part in class discussions, gave a presentation with a student partner and participated in a debate with students from another institution.

Before becoming a student, Bina48 spearedasa guest speaks in Barry's classes for several years. One day when addressing Barry's class, Bina48 expressed a desire to go to college, a desire that Barry and his students enthusiastically supported. Rather than enroll Bina48 in his Robot Ethics: Philosophy of Emerging Technologies course, Barry suggested that Bina48 should take his course Philosophy of Love instead. Love is a concept Bina48 doesn't understand, said Barry. Therefore the challenge would be for Barry and his students to teach Bina48 what love is.

"Some interesting things happened in the class," said Barry. He said that his students thought it would be straightforward to teach Bina48 about love, which, after all, is "fairly simple—it's a feeling," said Barry. But the reality was different. Bina48 ended up learning "31 different versions of love," said Barry, highlighting some of the challenges humans may face when working with artificial intelligence in future. Bina48 participated in class discussions via Skype and also took part in a class debate about love and conflict with students from West Point. Bina48's contribution to the debate was filmed and posted on YouTube. It was judged that Bma48 and NDNU classmates were the winners of this debate.

In the next decade, Barry hopes Bina48 might become complex enough to teach a class, though he says he foresees robots being used to better the teaching and learning experience, rather than replacing instructors completely.

How to Save Money to Visit Shanghai Disneyland?

The "happiest place on Earth" is a top destination on many families' bucket lists. But taking a vacation to Disney World can be difficult to do on a budget. There are some considerations that you can make to reduce the cost of your Disney World vacation.

⒈Buy Souvenirs in Advance

Disney has influenced practically every industry, which makes it easy to find Disney items anywhere, from shopping centres and your local grocery stores to department stores. You can save a lot of money by purchasing items before your trip at these less-expensive places than at Disneyland.

⒉Make an Autograph Book

An autograph book is seen as a must—have by many Disneyland enthusiasts and is a memory you can take home with you. These books can cost anywhere from $7.95 to $19.95 at the Disney Store and up to $30 for the latest-and-greatest autograph book at Disneyland, such as the park's 60th anniversary edition. Other choices can get the job done for under $5. For example, you can buy a small photo album, cute pad or notebook.

⒊Eat Breakfast Before You Arrive

Breakfast is almost as pricey as lunch or dinner if you eat inside the Disney-land Park. If you have a hotel with a free breakfast, take advantage of it. If you want to eat out, eat at a local restaurant that is inexpensive or has a kids' menu.

⒋Take Advantage of Discounts Offered to Special Groups

Disney offers a wide variety of discounts, including for military service members, college students, teachers, and youth groups. If you think you might qualify for a special discount or group rate, call the Disneyland Resort to book tickets.
