When Justin Tong was a child, other kids felt sorry for him. His parents always had him doing lots of housework such as carrying out the rubbish and sending newspapers. But when he grew up, he was better off than his childhood friends and lived a happier and healthier life.

This is the finding of a 40-year study that followed the lives of 456 children in London. It showed that the children who had worked hard in childhood had a richer and a happier future. "Children who worked in the home or community gained competence(能力) and came to feel they were worthwhile members of society," said Daniel Brown, the psychologist(心理学家) who made the discovery. "And because they felt good about themselves, others felt good about them."

Brown's study followed these children in great detail. Interviews were repeated at ages 25, 31 and 47. Under Brown, the researchers compared the children's mental-health scores with their childhood-activity scores. Points were awarded for part-time jobs, housework, effort in school, and ability to deal with problems.

    Working at any age is important. Childhood activities help a child develop responsibility, independence, confidence and competence — the underpinnings (基础) of emotional health. They also help him understand that people must cooperate and work toward common goals. The most competent adults are those who know how to do this.

    Yet work isn't everything. As Tolstoy once said, "One can live magnificently in this world if one knows how to work and how to love, to work for the person one loves and to love one's work."

I think ________ should be the star of the class. ……

At 15:40 on December 9th, 2021, the "space teacher", Wang Yaping, made some experiments in the Tianhe Core Module of the Chinese Space Station.

"Welcome to the ‘Tiangong Classroom!' " said Wang Yaping.

Taking a "spacewalk" is difficult. Ye Guangfu was working hard to walk, but his body floated! Then he tried to turn around but he couldn't. "In space, astronauts are in a weightless environment. So we need to use nearby devices (装置) to move," he said.

The paper flower "blooms". In the "Tiangong Classroom", Wang Yaping made a beautiful water film (水膜). Then she took out a paper flower and placed it on the film of water. The pink flower slowly "bloomed"! "I hope your dreams can bloom in the huge universe!" she said.

"Space Happy Ball" rings fun. Wang Yaping asked the children on the ground to put their ping pong ball in the water. The density (密度) of the ball was less than that of the water, so it floated up. In space, when she put the ping pong ball into the water, it did not float up to the surface. It stopped in the center of the water! "The buoyancy (浮力) disappears in a weightless environment in space so the ping pong ball cannot float (漂浮)." Ms. Wang explained.

Dear readers,

I am Li Hua. It is my honor to share my experience with you.

Most people choose to live in comfort after they retire ( 退休), but Wang Guilan is not one of them.As a marathon (马拉松)lover, the 70-year-old woman from Liaoning, China has completed over 100 marathons in the last 19 years. People call her Super Grannie".

Wang only started running at the age of 51, as a way to keep in shape, but soon realized she loved it. She ran her 1st marathon in 2004 and hasn' t stopped since. From 2005 to 2017 she completed the Beijing Marathon 13 times, and this year she set a new record, becoming the oldest person to ever complete the 168 -kilometer ultramarathon (超长距离马拉松) of Jiang Nan 100-Mile (а famous ultramarathon in China), in about 40.5 hours.

 "This lady is the same age as my grandmother. How can she run so fast? That's amazing," a young runner said after seeing Wang compete in Jiang Nan 100-Mile in April. This was Super Grannie' s 2nd time competing in the race.

So how does a 70-year-old stay in good-enough shape to complete a marathon that most people half her age couldn' t finish? According to Wang, she runs at least 20 kilometers six days a week from Monday to Saturday, and on Sunday she runs some more. She likes running in the mountains, but in winter, when the weather doesn't t permit, she runs on roads. On average ( 平均）, every year she runs for 7 months in the mountains and 5 months on the road.

Wang always believes that age is not a problem , and she plans to continue running marathons and enjoying her life for as long as she can.

Mrs. Morris lives on the top floor of our building. Every afternoon，she sits in a chair near the door of1 building. She always wears a smile and listens to me when I tell her about my days at school. 

One Tuesday，I ran into the building and hoped 2 my day with her，but her usual chair was empty. 

I looked for Mr. Low and asked what3 to Mrs Morris. "Oh，dear. Mrs. Morris is not feeling well 4 she is staying in bed today. "Mr. Low said. I wondered what I could do to make Mrs. Morris feel better. 

When Mom heard the news，she suggested making cookies 5 Mrs. Morris. We took out flour，sugar and butter. Maybe they 6 really make her better. 

When the cookies 7 ，we decided to visit Mrs. Morris without telling her. Mrs. Morris opened the door，looking surprised but 8 to see us. "Mrs. Morris，we bring 9 some healthy cookies，"I said. "We hope you feel better soon. "

"10 thoughtful gift!I feel better already!"Mrs. Morris smiled and said.
