I was shopping at a department store and had just got onto the down escalator（手扶电梯）when I noticed a woman standing to the side. She looked about 65, and her _______ told me she was scared. I turned _______ the woman and asked “Do you need any help?”

The woman remained silent. As the escalator continued moving, I heard the woman reply _______, “I’m afraid.” “Want me to come back and get you?” I called to her. She _______.

But by the time I reached her arm, the woman had reconsidered. “I don’t think I can do it,” she said. I suddenly realized that I had offered far greater help than I _______.

“I know we can do it,” I said. “I can hold on to you.” She looked down at the scary _______. Then her eyes came back to mine, looking doubtful. “This has never _______ me before,” she said, as much to herself as to me.

I took her _______. “Shall we?”

She made a little sound of _______ as we stepped on, but we’d passed the point of no return. To my joy, she ________ a little as the stairs moved us downward.

“I don’t understand this at all,” she said.

However, as we got near the ________, she felt scared again, but we did it.

“I’m so ________…” she began.

“It was nothing,” I said. “I was happy to do it.”

Happy, yes. I seldom help others. I am ________ because I care for a family and work full time. For a short moment, I seemed to understand ________ someone would become a nurse or a social worker or something else. Not only did I help the old lady get on the escalator, but also helped her ________ her fear. It was a much happier moment than I’d had in weeks.

March 21 is World Sleep Day. Here are some facts about sleep.

Sleep at advised times

In 2021, the Ministry of Education（MOE）advised that junior and senior high school students should go to bed before 10 pm and 11 pm respectively（分别的）.

How do astronauts sleep

Just like on Earth, a person in space goes to bed at night and then wakes up the next day. But in space there is no up or down, and you do not feel the pull of gravity（重力）. As a result, astronauts usually sleep in fixed sleeping bags.

Earworms happen while sleeping

Some people enjoy listening to music a lot. While we’re awake, the music we know well keeps ringing in our ears, which is called earworms（耳虫现象）. This can happen during sleep as well, which could cause problems in getting to sleep and staying asleep.

Sleep with your pet

Pets, like dogs and cats, do not sleep continuously and they will often get up and walk on the bed, which can make you sleep even worse.

But recent studies found that having pets in the bed may help people who are often worried. The pets, like soft toys, can help cut down their worry.

Socks can help us sleep

Studies have shown that wearing socks to bed can help you fall asleep faster!

Hands and feet help exchange（交换）heat between the far ends of the body and the heart. Wearing socks means an increase of blood to your hands and feet, which cuts down your core（核心的）body temperature. The lower the core body temperature is, the faster you fall asleep.

China will have 75 percent of its wild animals on land under the national key protection system by 2025, the National Forestry and Grassland Administration（国家林业和草原局）said. Its announcement took place on Sunday, which happened to be the International Day for Biological Diversity（多样性）.

The administration said that part of China’s achievements in protecting wild animals lie in setting wild animals into nature reserves（保护区）after human breeding（繁殖）. It said that nine milu deer（麋鹿）recently came into the world in the Daqingshan National Nature Reserve in Inner Mongolia. They are babies of the milu deer, or Pere David’s deer, who were set into the wild in September following human breeding in Beijing and Jiangsu province.

According to the administration, human breeding has helped to increase the population of some animal kinds that had before disappeared in the wild, such as milu deer and Przewalski’s horses. There are now around 10,000 milu deer and around 700 Przewalski’s horses. As for other wild populations, the giant panda population has increased from 1,114 in the 1980s to 1,864. The number of wild Asian elephants has increased from about 180 to 300 over the same period.

The administration plans to improve the protection of wild animals—including giant pandas, Siberian tigers, Asian elephants, and snow leopards.

At the same time, the government has made more efforts to punish unlawful trading in wildlife, which also helps with the increase of wild animals.

For pupils at a village school in Yiyuan county, Shandong province, Ren Jilan has not only been teaching them but also showing them how to face life bravely, especially when things just don’t seem to be working out.

Ren came from a poor family in a Yiyuan county village. She had to do more housework than other children when she was young because both her father and mother were in ill health. With support from her relatives and villagers, Ren completed her 12-year school study and was accepted by Qufu Normal University. But the four-year university experience didn’t go well. Her father died and then she had to care for her mother. At the difficult moment, it was her teacher, Li Zhenhua, who came to her and offered help.

After graduation, Ren was faced with chances to work as a teacher in cities, but she chose to return to her hometown and work as a country teacher at Fuluping Primary School. “Teacher Li gave up a well-paid job in a big city to teach children at the village school. I’d like to follow his path to play my part for the education in my hometown.” Ren says.

Fuluping Primary School is 50 kilometers away from downtown Yiyuan county. It was once among the schools with the worst conditions in the county. But the school has its own beautiful and comfortable playground now.

Ren works hard on teaching and taking care of her students. She also spends a part of her money helping two poor students. She received the China Youth May 4th Medal—the country’s top honor for excellent young people.

“Life was not easy for me, but luckily I had nice people around me. They gave me a helping hand when I was in need, and it encouraged me to go on,” says Ren.
