Under new rules posted by the Civil Aviation (航空) administration of China on Friday, pilots will have to pass a “level four” test of Mandarin Chinese, China's official language. Those who speak with an accent that “often impedes” comprehension will not pass. These rules take effect in January 2016.

    China's 56 ethnic groups speak more than 80 languages and dialects. Even native Mandarin speakers can have trouble communicating with each other depending on the strength of their accents, which can be mutually unintelligible (难理解的).

    One flight trainer illustrated the scope for linguistic confusion, especially when common English aviation terms are used. Asked if there is a problem on board, a Chinese pilot might answer in the negative with the words mei you, or “there isn't.” But someone speaking with a heavy Sichuan accent would pronounce mei you as “May day” — unconsciously parroting the universally recognized distress call (遇难信号).

    Like their international counterparts (对应物), Chinese aviators have developed codes to avoid confusion resulting from homonyms (同音异义字) or near-homonyms. They use the terms yao for one and guai for seven, which are otherwise pronounced yi and qi respectively and easily confused.

    The new rule could affect all pilots, who must renew their license every six years, and adds to a growing list of burdens for the profession.

    Nola is a 41-year-old northern white rhino (犀牛) that lives at the San Diego Zoo Safari Park in Escondido, California. She is one of only four remaining northern white rhinos in the world, and the only one in the western part of the earth. The other three live in Kenya (肯尼亚).

    Rhinos have lived on earth for more than 40 million years, but they are now at the risk of dying out. Hunters illegally hunt rhinos for their horns (角), which are used for art, jewelry, and decorations. They sell the horns for thousands of dollars per pound, though it is not allowed by law. Rhino horns are also prized as a key part in traditional medicine, even though scientific tests have proven that the horns cannot cure illnesses. Experts say that every eight hours, one rhino will be hunted.

    Scientists are trying to find ways to prevent rhinos from dying out. In 1975, the San Diego Zoo Institute for Conservation Research started the Frozen Zoo, a program through which researchers have collected cell samples (细胞样品) from more than 8, 000 different animal species until now, including the northern white rhino. Scientists hope that by studying the rhino cells, they will gain greater understanding of the species, and will find ways to increase its number.

    Jeanne Loring works with the Frozen Zoo. Loring's research focuses on pluripotent stem cells, which are cells that can renew and become any cell type. Coloring's lab at TSRI is working together with scientist Oliver Ryder of the San Diego Zoo to use plenipotentiary stem cells to try to increase the number of the northern white rhino. Loring said the goal is to start producing new rhinos through this method over the next couple of years.

The rolling out of 5G services has triggered a wave of competition across the world. More importantly, it has started a race to develop 6G as the telecommunications sector has always been a hotspot for competition.

Compared with 5G technology, 6G will have lower latency, higher speed and more bandwidth. And this advanced technology will help connect the real world with virtual digital world. It will also make product design R&D(Research and development) and experiments significantly more efficient and greatly reduce their costs while making it possible to produce digital products. In the physical world through high-tech, including 3D printing. The seamless and intelligent connection of the physical and digital worlds will lead to a thorough reconstruction of the division of labor and societal cooperation.

In terms of economic development, 3G fostered e-commerce while 4G boosted e-commerce and mobile payment. 5G infrastructure building and application marked the beginning of intelligent manufacturing. Similarly, wireless cognition technology associated with 6G technology, once it matures, will further boost the development of the digital economy. In digital economy, intelligence based on big data will become the real force for innovation and 6G networks not only will be highways for transmitting data, but will also much more seamlessly integrate edge and core computing as part of a combined communications. This will provide many potential advantages as 6G technology becomes operational, including access to AI capabilities. Digital economy based on 6G will become the determining factor of the country's competitiveness in the future, and 6G technology with wireless cognition as its major characteristic will become core technology and main driver of the digital economy.

Starting with 5G our telecom industry, thanks to its extensive R&D input, has taken the lead in standardizing and manufacturing 5G telecom equipment，the competition in 6G will start with the setting of standards, which will determine the level of R&D needed for the launch of the technology and thus decide the market share of the emerging industry . As far as R&D in 5G technology is concerned. We have already enjoyed two advantages. first, it is a global leader in the telecom sector and has a solid reserve of talents. And second, it has a relatively complete industrial chain that covers R&D and design, manufacturing and application. and is home to leading 5G equipment maker. Recent history shows whoever leads the telecom technology sector sets the standards for telecom products and services. and plays a bigger role in the industry's future development . An official research team on 6G including the government. enterprises and research organizations has been established to obtain the advantage of 6G development competition .

After years of travel it was bound to happen. Waiting by the moving belt, I watched the suitcases make mocking(嘲弄的) rounds. My companions, exhausted after16hours in the plane, were sympathetic and relieved. They were all thinking: at least it wasn't me. Any moment now, I told myself, swearing at the happy vacationers busy collecting their things. What about my necessities (必需品)?

For millions of travelers a year, it happens. Their missing bags stolen, sold in blind auctions(拍卖), or gone forever without any explanation. Today it was my turn, in a crowded Indian airport, as far from home as I'd ever been.

So, while the airline hunted for my belongings with no any order or plan and asked whether I would rather have $200– I found myself wandering the hot streets of Delhi in an orange dress and a pair of blister-producing ballet flats. Equipped with my carry-on (contents: eyeglasses, a paperback, an ancient tube of Chapstick), I was forced to "manage".

Day two, good news. The bag had been found! Bad news: it is still sitting in Toronto. Did it miss me as much as I missed it?

But then, a twist. I survived. By day three, I was secretly enjoying myself. What to wear? Hello, orange. Make-up today? Not an option. With almost nothing, I found better things: a new understanding of necessity, a short break from my obsession(痴迷) with stuff, stuff and more stuff, and a new appreciation for what does matter (the Taj Mahal) , when my bag finally made its way back to me.

That's right, my jam-packed blue suitcase resurfaced – on day four – and I suddenly had a rainbow of ten dresses to choose from. I decided to wear my orange dress once more, for good luck. It worked: nothing went missing on my journey home.

Is forgiveness against our human nature? To answer our question, we need to ask a further question: What is the essence of our humanity? For the sake of simplicity, people consider two distinctly different views of humanity. The first view involves dominance and power. In an early paper on the psychology of forgiveness, Droll (1984) made the interesting claim that humans' essential nature is more aggressive than forgiving allows. Those who forgive are against their basic nature, much to their harm. In his opinion, forgivers are compromising their well-being as they offer mercy to others, who might then take advantage of them.

The second view involves the theme of cooperation, mutual respect, and even love as the basis of who we are as humans. Researchers find that to fully grow as human beings, we need both to receive love from and offer love to others. Without love, our connections with a wide range of individuals in our lives can fall apart. Even common sense strongly suggests that the will to power over others does not make for harmonious interactions. For example, how well has slavery worked as a mode of social harmony?

From this second viewpoint of who we are as humans, forgiveness plays a key role in the biological and psychological integrity of both individuals and communities because one of the outcomes of forgiveness, shown through scientific studies, is the decreasing of hatred and the restoration of harmony. Forgiveness can break the cycle of anger. At least to the extent the people from whom you are estranged accept your love and forgiveness and are prepared to make the required adjustments. Forgiveness can heal relationships and reconnect people.

As an important note, when we take a Classical philosophical perspective, that of Aristotle, we see the distinction between potentiality and actuality. We are not necessarily born with the capacity to forgive, but instead with the potential to learn about it and to grow in our ability to forgive. The actuality of forgiving, its actual appropriation in conflict situations, develops with practice.
