I am 26. I'm clear that I'm never going to catch up with Mother Teresa. But I want to do something to help people every single day like her.

    Everybody thinks we just serve food and soda. The safety training is serious and stressful. Caring for 49 people in a business class in 90 minutes is not easy. I had a roommate who was a waitress; she just left a candle and a table cloth burning, and I used a fire extinguisher to put out the fire. If something goes bad at her job, she calls the police. But if something happens up in the air, it's up to us.

    I'm single and have no kids. I've flown every Christmas since 1995. If I fly, someone else can be with their kids. Christmas in an airport can be depressing, but it's the little things that make a difference.

We're not robots. It's hard to put on a smile and just pretend everything is great when it isn't. I've seen co-workers lose a family member the day before a trip and just pull themselves together (take control of their feelings and behave in a calm way). At the end of a 14-hour flight, it's like, "It was really nice to help you, but I'm ready for you to get off the plane." Those last 15 minutes can be the longest 15 minutes of your life. You can't wait to turn off the flight attendant's voice and get something to eat without anyone saying "Excuse me."

Sometimes I go all day and never hear a "please" or a "thank you" when you say "thank you", it's huge. It makes us feel like you actually see us as fellow humans. We're up there together at a height of 30,000 feet, enjoying the miracle of the modern flight.

    Many Americans buy an evergreen tree for Christmas. They put the tree in their home and hang small lights and colorful things on it. The evergreen is usually a pine or a fir tree (冷杉树). It remains green during the cold, dark months of winter in the northern part of the world. So it is a sign of everlasting life.

    Early long ago, Romans probably planted evergreen trees during a celebration in honor of their god of agriculture. The Christmas tree may have developed from a popular play performed hundreds of years ago in what is now Germany. Traditionally, the play was on December 24th, the day before Christmas. The play was about the first people that God created—Adam and Eve. People put apples on an evergreen tree to represent the tree of knowledge in the Garden of Eden.

    By the year 1600, some Germans began bringing evergreen trees into their homes. They put fruit, nuts and sweets on the trees. They gave the food to the family members and friends after the holiday season. Some people say the German religious reformer (宗教改革者) Martin Luther was the first person to add lighted candles to the tree. They say he did this to show how wonderful the stars had appeared as he travelled one night.

    In the early 1800's, German settlers in the state of Pennsylvania were the first to celebrate the holiday with Christmas trees in the United States. The Christmas tree tradition spread to many parts of the world. Today, some form of the Christmas tree is part of most Christmas celebrations.

    Alice Robb is an American science journalist who has written for the Washington Post and the New Republic. Her new book, Why We Dream, encourages us to rethink the importance of dreams and to become dream interpreters ourselves.

    Reporter: Recently there's been a massive interest in the science of sleep. Sleep plays a role in maintaining our mental health. Are dreams part of that process?

    Alice Robb: Dreams play a big role in helping us cope with stress, grief and psychological problems. Dreams are an opportunity to work through things that frighten us in real life, to play out worst-case situations in an environment where they have no consequences.

    Reporter: Has anyone explained why dreams contain such surreal (超现实的) elements, strange pictures of time, people, geography and so on?

    Alice Robb：When we dream, the logic centres of our brain—the frontal lobes (大脑额叶) —go dark, and chemicals associated with self-control, like serotonin (血清素) and norepinephrine (去甲肾 上腺素) , drop. At the same time, the emotion centres light up：we have a perfect chemical canvas for dramatic, psychologically intense visions.

    Reporter：You say neglecting to consider our dreams is like "throwing away a gift from our brains without bothering to open it. " What is the gift?

    Alice Robb: When we're dreaming, we're thinking in a state we never have access to by day. Dreams offer the opportunity to think in a different way and show new answers to problems. They show us blind spots on things we might be neglecting in our personal lives.

Lack of sleep among children and teenagers in China has worsened in the past decade, with more than 80 percent getting insufficient sleep on school days, a new report has found.

Chinese youngsters snooze 7. 8 hours a night on average on school days, down 0. 3 hours from 2009, according to the report released on Monday by the Chinese Academy of Sciences'Institute of Psychology.

Researchers surveyed more than 15,800 students from Henan, Hebei and Guangdong provinces from April to July, asking what time they go to bed and wake up on days they take offline classes on campus.

Only 46. 4 percent of them sleep for at least 8 hours, compared with 47. 4 percent in 2009.

According to an action plan laying out measures to be taken from 2019 to 2030 to promote the health of citizens, primary school students are recommended to get a minimum of 10 hours of sleep a night. For junior high school and senior high school students, the recommended sleep durations per night are 9 and 8 hours respectively.

By this set of standards, more than 95 percent of students from primary schools, nearly 91 percent at junior high and 84 percent at senior high, did not get enough sleep on school days, heightening the risk of them developing cognitive, mental and physical health problems, the report said.

Hou Jinqin, a researcher at the National Institute of Education Sciences who co-authored the study, suggested local authorities implement measures instructed by the Ministry of Education, such as lessening academic burdens, postponing start times at school and encouraging children to be enrolled at institutions closer to home, in order to prolong sleeping hours.

In terms of the COVID - 19 outbreak's impact on sleep, she said available research overseas shows school closures forced by the COVID - 19 epidemic have added two hours of sleep to young students studying-gat home.

In China, some studies have revealed no marked differences in sleeping patterns of students before and after school reopened, she added.
