When Russell Lyons volunteered for the first time, he read “Goodnight Moon” to a class of San Diego preschoolers. And it wasn't reading — he'd memorized the book and was reciting it out loud. He was 4. Still, he said it felt good there, in front of the other kids, lending a hand. He wanted more of that feeling.

    Thirteen years later, he's getting a lot of it. He's on a five-month road trip across America — not sightseeing, but volunteering.

    The University City resident has spent time at an animal reserve in Utah, a women's shelter in St. Louis, a soup kitchen in New York, a retirement home in Tucson. This week he's in Los Angeles, at a program that supports disabled youth.

    “I just like helping people and feeling that something I do is making a difference,” he said. He resists the idea that his “Do Good Adventure” is all that unusual. It bothers him that the media often describe young people as lazy, self-centered. So he sees his trip as a chance to make a statement, too. “About 55 percent of teens do volunteer work, higher than the rate for adults” he said, according to a 2002 study. “Not everybody knows that. ”

    Of course, some teens do volunteer work because it looks impressive on their college applications. Lyons said he mentioned his trip on his applications. But charity work is a habit with him. Even before the cross country trip, he was volunteering about 200 hours a year at various places. He's made sandwiches for homeless families in Washington D.C. He's taught math to fifth-graders in Cuernavaca, Mexico.

    He gets some of that drive from his mother, Lesley Lyons, who has been involved in nonprofits for much of her life. She was there when her son “read” to the preschoolers — a memory of hers “that will never go away.”

    Teenagers who spend hours in front the television may have a poorer diet as young adults.

    A study, which included nearly 1,400 high school students, found those who watched TV for five hours or more per day had less healthy diets than peers(同龄人) five years later. Why does this happen? Should the parents take any measures?

    On the one hand, people who spend a lot of time in front of the TV, especially teenagers, may snack more, and that may affect their long-term diet quality.

    On the other hand, TV ads for fast food, sweets and snacks tempt teenagers to eat more of those foods. And TV time might also replace exercise time for some kids.

    Lead researcher Dr. Daheia J. Barr-Anderson, of the University of Minnesota in Minneapolis, told Reuters Health a clear correlation between TV time during high school and diet quality in young adulthood. While the heaviest TV viewers were eating the most junk food, those who'd watched less than two hours per day had the highest intake(吸收) of fruits, vegetables, whole grains and high-calcium food. In her opinion, parents should limit and monitor TV viewing.

      As far as I am concerned, children should watch no more than two hours of television per day. And parents should set a good example by eating right, being physically active and curbing their own TV time.

    Prateek Sharma was born into a family of farmers. After 10 years of being a chief manager of Kotak Mahindra Bank, he did a good job and earned a good pay. But Prateek couldn't continue the corporation life with ease, as his heart was always in farming. So he worked as a banker on weekdays and on weekends travelled 100 km to get to his 5-acre in Dhaba Khurd.

    By the end of 2015, Prateek had set up a house on his farm to grow offseason vegetables. Prateek thought he'd quit his job once he was able to earn enough from farming, but this wasn't an easy decision to make. This was because costs to grow these vegetables were very high, along with the fact that farmers weren't a part of the value chain and thus couldn't decide the price of their own vegetables.

    Fortunately, Prateek met Vinay Yadav, another educated farmer. They then decided to start their own value chain and sell their vegetables and grains, while skipping the middlemen. The variety of vegetables they grew wasn't enough, so they decided to form a group of farmers.

    Once the plan was ready, the group was registered by the name of Farmer Producer Organization (FPO). However, the trial failed in the first year as most of the farmers were grain growers and had limited knowledge of growing vegetables. However, the largest reason was the switch to organic from chemical.

    Luckily, once the soil was used to organic methods, the next round of crops were successful and the FPO had a good amount of produce. So at the end of 2017, Prateek finally quit his job and devoted all his time to farming. Now he's successful and recently his team has started two farmer resource centers at Dhaba Khurd and Nathrula Canj.

    When I lived in Spain, some Spanish friends of mine decided to visit England by car. Before they left, they asked me for advice about how to find accommodation. I suggested that they should stay at 'bed and breakfast' houses, because this kind of accommodation gives a foreign visitor a good chance to speak English with the family. My friends listened to my advice, but they came back with some funny stories.

"We didn't stay at bed and breakfast houses," they said, "because we found that most families were away on holiday."

I thought this was strange. Finally I understood what had happened. My friends spoke little English, and they thought 'VACANCIES' meant 'holidays', because the Spanish word for 'holidays" is 'vacancies'. So they did not go to house where the sign outside said 'VACANCIES', which in English means there are free rooms. Then my friends went to house where the sign said 'NO VACANCLES', because they thought this meant the people who owned the house were not away on holiday. But they found that these houses were all full. As a result, they stayed at hotels!

    We laughed about this and about mistakes my friends made in reading other signs. In Spanish, the word 'DIVERSION' means fun. In English, it means that workmen are repairing the road, and that you must take a different road. When my friends saw the word 'DIVERSION' on a road sign, they thought they were going to have fun. Instead, the road ended in a large hole.

English people have problems too when they learn foreign languages. Once in Paris, when someone offered me some more coffee, I said "Thank you" in French. I meant that I would like some more. However, to my surprise the coffee pot was taken away! Later I found out that "Thank you" in French means "No, thank you."

    Many high school students consider a college education useless. Therefore, they choose not to go to college. If you're one of them, think again. Here are some reasons why you should go to college and receive a good education there.

    Schools and universities are the first sources of knowledge. We take that knowledge later on to build our careers after graduation. More knowledge will be gained after you start working, but without an education, that job will not be within easy reach. Knowledge leads to knowledge.

    While limited within the walls of the educational institutions, we openly explore other cultures of the world. We come to know that ours is not the only culture. Other cultures have valuable insights to share, enriching our own. Education also makes us want to travel and interact with various cultures, broadening our horizons.

    When there's a downturn (衰退) in the economy, those who attended college will be more likely to find a new job than those who only finished grade school and have a limited skills set. The more education you have, the more chances you will get to improve the quality of your life as you have a better job and earn a higher salary.

    When you're skillful and knowledgeable, you get to “rub knees” with people of similar backgrounds and tastes. It means a good education leads to excellent networking. Good networking can benefit you a lot in your later life.

    A good education makes you a more interesting person. You can talk about ideas and events instead of just other people and what's on sale in stores. An educated person doesn't gossip, having a preference to discuss ideas and listen to what other people have to say.

Dark Sky Parks around the World

    Warrumbungle National Park

    Situated in the central west slopes of New South Wales is Australia's only dark sky park, Warrumbungle. The park has served as a dark sky park since July 2016. Its crystal-clear night skies and high altitude make it a natural, educational, and astronomical heritage site in the southern half of the earth. Tourists can use Australia's largest optical telescope within the park boundaries to view the auroras (极光), the Milky Way, and faint shooting stars.

    Sark

    Sark is a Channel Island near the coast of Normandy under the protection of the UK. It was the World's First Dark Sky Island set up in January 2011. Its historical and cultural blend attracts over 40,000 tourists annually. With no motor vehicles and public lighting on the island, there is an exceptional view of the dark skies. A rich Milky Way is visible in the dark night skies from the shores of the island.

    Pic du Midi de Bigorre

    Pic du Midi de Bigorre in France was designated as a dark sky park in December 2013 making it the second largest dark sky park in the world. The park covers 3. 112 square kilometers spread across the Pyrenees National Park and UNESCO's World Heritage site, Pyrenees-Mont Perdu. The park attracts over one hundred star watchers every year. The Observatory Midi-Pyrenees, which was built in 1870, is one of the world's highest museums at a height of 2,877 meters above sea level.

    Ramon Crater/Makhtesh Ramon

    Ramon Crater is a unique 1,100-square-kilometer nature reserve located in the Negev Desert in Israel. In 2017, the Ramon Crater became the first designated dark sky park in the Middle East. Its location, rough climate, and forbidding landscape that are characteristic of the Negev have largely defeated historical attempts for human settlement, making it a great place to view the night skies. Stargazers usually camp in the desert to have an uninterrupted view of the stars, planets, and the Milky Way.
