Mark was an 11­-year­-old orphan who lived with his aunt, and he was a sweet and gentle child.

I had not noticed Mark particularly until he began staying after class each day to help me clean the room. Mark spoke mostly of his mother. Though he was quite small when she died, he remembered a gentle, loving woman, who always spent a lot of time with him.

As Christmas drew near, however, Mark failed to stay after school each day. I looked forward to his coming, but he continued to leave from the room hurriedly after class. I stopped him one afternoon and asked why he no longer helped me in the room.

"I was making you a surprise," he whispered. "It's for Christmas." With that, he became embarrassed and ran from the room.

Finally came the last school day before Christmas. Mark crept into the room late that afternoon with his hands hiding something behind his back. "I have your present，" he said shyly when I looked up. "I hope you like it." He held out his hands, and there lying in his small palms was a tiny wooden box.

"It's beautiful, Mark. Is there something in it？" I asked, opening the top to look inside.

"Oh, you can't see what's in it，" he replied. "And you can't touch it, or taste it or feel it, but Mother always said it makes you feel good all the time."

I stared at the empty box. "What is it, Mark," I asked gently, "that will make me feel so good?" "It's 11 ," he said softly, "and mother always said it's best when you give it away." And he turned and quietly left the room. So now I 12 the small box on the piano in my living room. Yes, Christmas is for joy, songs and nice gifts, but mostly, for love.

The hotly anticipated(预期的) new Spring Festival movies were finally released, and broke the single­day box office record. Among them, Hi, Mom is the most popular. The audience has given it the top rating in a satisfaction survey conducted by the China Film Art Research Center.

Hi, Mom stars Jia Ling as a devoted daughter, who, deeply saddened by her mother's death in an accident, finds herself transported back to 1981. Jia shared youth with her young mother and chased her dream. In this comedy film about a mother's youth, we saw many happy scenes: Jia helped her mother win the chance to buy a TV set, organized female workers and her mother to take part in volleyball games, and helped her mother and the factory director's son Shen Guanglin fall in love. She used her own way to make her young mother happy.

In the constant laughter, there is a hidden line. Jia, who travels through time and space, wants to help her mother change her destiny. She hopes that her mother could have a successful career, a wealthy family, and a very excellent child who could bring her honor. But the young mother also transported to the past and helped Jia. At the end of the film, Jia finally realizes that the best way to make her mother happy is to cherish her child — herself in this case.

The comedy, which Jia described as a present to her real­life mother who passed away tragically around two decades ago, brought many moviegoers to tears. It also sparked people to think more about mother­daughter relationships, with netizens(网友) sharing old photos of their own mothers at their young age. This reminds us to love our mother more in the real life and cherish time together.

We are still going on journeys, still travelling but in a slightly more sedate manner. Because of the time we live in, we are rediscovering the simple and healthful joys of walking. In the countryside, through forests, down hills or along ancient trails, this manner of travel has become increasingly popular in the country in the aftermath of COVID­19.

From May 1 to Oct.31 in 2020, more than 140，000 travelers signed up for trips organized by Youxiake, a Hangzhou­based tour operator that invites people to explore nature by foot. This represents a 9. 3 percent increase over the same period last year. And the number of hikers marching along its routes has doubled, according to Huang Bowei, marketing director of the company. Not surprisingly, more tourists are choosing to explore domestic(国内的) routes, according to Huang.

"After the outbreak, people became more aware of keeping fit，" Huang says. "Hiking or trekking in nature enables us to breathe fresh air, gives the whole body a workout and keeps us away from the crowds in urban public places, which fits perfectly with the requirement for social distancing. That's why these domestic hiking or trekking routes have seen more visitors this year."

Zhang Peng started spending hours on the trail in 2013 when his startup business went through some tough times. "I felt that exposure to nature and physical exhaustion(疲惫) helped me release my stress at that time，" Zhang recalls.

"Trekking has been integrated into my lifestyle，" he says. "It's a liberating experience to enjoy the calmness in the wilderness. And the exhausting climb makes me feel the vigor(活力) of life."

How long does a year last?Your parents might say that a whole year can pass "in the blink of an eye". Why does time seem to pass faster as we get older?

This physical change causes the rate at which we take in and process new information to decline. Babies, for example, move their eyes much more often than adults because they're processing images at a faster rate. They take in a lot of information and do many things in a single day.However, as people's brains degrade(降低) over time, fewer images are processed in the same amount of time. Therefore, older people receive less information during a day than younger people. This causes things to seem as though they're happening more quickly.

People may measure time by the number of memorable events that can be recalled within a certain period. Have you ever noticed that when you recall your firsts, they seem to be in slow motion? That's because when something is a "first"， there are many exciting things to remember. Recalling these memories makes you feel like that they took forever. For many adults, life is routine(平淡的). When they look back, they might feel like there are not many novel(新奇的) things to remember.
