3 . That dinosaurs ate the mammals (哺乳动物) that ran beneath their feet is not in doubt. Now an extraordinary fossil newly described in Scientific Reports, unearthed by a team led by Gang Han at Hainan Vocational University of Science and Technology in China, shows that sometimes the tables were turned.

The fossil -dated to about 125 million years ago, during the Cretaceous period-was formed when a flow of boiling volcanic mud swallowed two animals seemingly locked in a life-and-death fight. The one on top is a mammal. This animal is a herbivorous species closely related to the Triceratops (三角恐龙). Animal interactions such as this are exceptionally cam e in the fossil record.

One possibility is that the mammal was eating something already dead, other than hunting live prey. These days it is uncommon for small mammals to attack much larger animals. But it is not unheard of. And Dr. Han and his colleagues point out that those mammals which eat dead bodies typically leave tooth marks all over the bones of the animals. The dinosaur’s remains show no such marks. There is also a chance the fossil could be a fake. More and more convincing fake s have emerged, as this one did -though Dr. Han and his colleagues argue that the complexly connected nature of the skeletons (骨骼) makes that unlikely, too.

Assuming it is genuine, the discovery serves as a reminder that not all dinosaurs were enormous during the Cretaceous and not all mammals were tiny. From nose to tail, the dinosaur is just 1.2 meters long. The mammal is a bit under half a meter in length. Despite being half the size, the mammal has one paw firmly wrapped around one of its prey’s limbs, and another pulling on its jaw. It is biting down on the dinosaur’s chest, and has ripped off two of its ribs. Before they were interrupted, it seems that the mammal was winning.

4 . Jenny married Steven in 1950. They loved each other but Steven had bad tempers. As a new bride(新娘), Jenny moved into Steven’s house on his farm. She took a shoe box with her and put it in her closet (壁橱). She asked Steven not to open the box. Thinking that everyone has his/her secret that he/she never wanted others to know, Steven accepted it.

For 50 years, Steven left the box alone, even without touching it. Finally, Jenny was ill and dying. Steven thought the box must hold something very important and it was time to open it, so he asked Jenny whether he could open the box. Jenny said yes.

Opening the box, Steven found two doilies(装饰小垫) and $82,500. He took the things to Jenny and asked where this came from.

“Well, my mother gave me the box the day we got married,” she explained, “She said that love needed understanding, so did life. She knew you had bad tempers, so she told me to make a doily whenever I felt hurt and frustrated(沮丧), so that I wouldn’t get mad at you.” Steven was glad that in the past 50 years Jenny had made only two doilies. Then he asked about the money.

“In fact, after having made too many doilies, I began to sell them. Each brought us $50. That’s the money I’ve made by selling the doilies.”

Hearing this, Steven couldn’t help crying…

Everyone gets three presents in life. Life is the first one; love is the second and understanding is the third. It is love that gives us lives and understanding, while understanding keeps love.

6 . During my university years in the early 2000s, I worked part-time with kids at a neighborhood YMCA, which mainly focused on child care. Each year, we hosted a Christmas party for the community.

Most of the people working there were women, so we had to search for a male volunteer to play Santa Claus. We didn’t have many choices. John was a tall, twentyish man who was much too thin to be Santa Claus. No amount of stuffing (填充物) could possibly make him look like a common Santa Claus. He was, however, available.

On the day of the party, John put on his costume (戏装) and waited for the children. Many of the children who knew John said, “It’s just you, John.” If they didn’t know him, they said, “You’re too thin to be Santa.” We thought it might be a bad decision, but then everyone seemed to enjoy their time there, so it didn’t really matter.

Then, a lovely little girl entered the room. She was dressed beautifully to see Santa and seemed a little shy. Her mother brought her up to our Santa. “She’s deaf,” the mother explained. “If she could just sit on your lap (大腿) and have her picture taken, she would be happy.” John, the skinny Santa, smiled at the little girl, and she sat on his lap.

Then, the skinny Santa began using hand gestures to communicate with the girl fluently, and the little girl smiled happily and answered him quickly with her hands. Their conversation lasted quite a while. When I looked at the mother, I saw that she was crying. In fact, I don’t think there was a dry eye in the room. Santa Claus really was there.

There was so much we didn’t know about what was happening. This girl had never met John before, and few of us were aware that he knew how to sign — it all added up to a magical surprise.

8 . Humans have long known that being in nature is good for the mind and body. From indigenous (本土的) adolescents completing the adult ceremony in the wild to modern East Asian cultures taking “forest baths”, many have looked to nature as a place for healing and personal growth. But the question still remains. How can nature make it?

There is no doubt that being in nature reduces the physiological symptoms of stress in our bodies. What this means is that we are less likely to be anxious and fearful in nature, and therefore we can be more open to other people and creative patterns of thought. Also, nature often leads to awe, wonder and respect, all these emotions facilitating everything from physical to mental health. There is also some evidence that exposure to nature impacts the brain. Viewing natural beauty makes specific reward circuits in the brain associated with dopamine release, a chemical that gives us a sense of purpose, joy and energy to pursue our goals.

But, regrettably, people seem to be spending less time outdoors and less time in nature than before. It is also clear that, in the past 30 years, people’s levels of stress and sense of “busyness” have risen dramatically. These joint forces have led environmental writer Richard Louv to coin the term “Nature Deficit Disorder”—a form of suffering that comes from a sense of disconnection from nature and its powers.

Perhaps we should take note and try a course corrective. The 19th century philosopher Ralph Waldo Emerson once wrote about nature, “There I feel that nothing can befall me in life—no disgrace, no calamity.” The science speaks to Emerson’s intuition. It’s time to realize that nature is more than just a material resource. It’s also a pathway to human health and happiness.
