     If you could have one superpower, what would it be?

     Dreaming about whether you would want to read minds, see through walls, or have superhuman strength may sound silly, but it actually gets to the heart of what really matters in your life.

     Every day in our work, we are inspired by the people we meet doing extraordinary things to improve the world.

     They have a different kind of superpower that all of us possess: the power to make a difference in the lives of others.

We're not saying that everyone needs to contribute their lives to the poor. Your lives are busy enough doing homework, playing sports, making friends, seeking after your dreams. But we do think that you can live a more powerful life when you devote some of your time and energy to something much larger than yourself. Find an issue you are interested in and learn more. Volunteer or, if you can, contribute a little money to a cause. Whatever you do, don't be a bystander. Get involved. You may have the opportunity to make your biggest difference when you're older. But why not start now?

     Our own experience working together on health, development, and energy the last twenty years has been one of the most rewarding parts of our lives. It has changed who we are and continues to fuel our optimism about how much the lives of the poorest people will improve in the years ahead.

    Nobody is sure where and when the expression “apple-pie order” began. Some say that Scottish and English writers used the expression a long time ago. Others say it was first used in the northeastern American states known as New England. The housewives of New England cut their apples in even slices. Then they filled pie pans with them in an organized way, row upon row. As one writer said, the women of New England loved to have everything in its place. This perhaps explains why it generally is believed that the expression “apple-pie order” began in New England.

    Another old expression, “apple of discord”, comes from ancient mythology(神话), however. The myth says that all the gods and goddesses were sitting around the table to celebrate the marriage of Thetis and Peleus. One of the goddesses-Discord was a troublemaker. She threw away a golden apple on the table to be given as a prize to the most beautiful goddess.

    At one time, the tomato was called a love apple. That was a mistake. This is how the mistake happened: In the sixteenth century, Spain brought the tomato from South America after Spanish explorers had landed there. Spain then sold the tomato to Morocco. Italian traders carried it on to Italy. The Italian name for the tomato was “pomo di Moro” meant “d'amour” -the French word for love. And so “pomo di Moro” became the apple of love.

    People believe many things about the apple. One belief is that it has great powers of keeping people healthy. A very common expression is "an apple a day keeps the doctor away."

    Another belief is based on fact. The expression is "one rotten apple spoils the barrel." When an apple begins to go bad, it ruins all the other apples around it in the container. The expression has come to mean that one bad person in a group can cause everyone to act bad.

    Being seen in a fancy sports car or enjoying a beach holiday in a five-star hotel were once signs of having “made it”.

    But a new study suggested that having people think of you as constantly busy and overworked is now a far better way to show social status.

    According to Harvard University in the US, people are increasingly leaning toward the phenomenon of “humblebragging (谦虚自夸)”. This is when people make a seemingly modest statement that actually draws attention to something they want to brag (吹嘘) about.

    Phrases such as “I have no life” and “I desperately need a holiday” are now used to imply social standing, while ordering food and shopping online is the perfect way to prove to neighbors that you are simply too busy and important to go to the supermarket.

    “Movies, magazines, and popular TV shows often highlight (强调) the abundance (富足) of money and leisure time among the wealthy,” said Neeru Paharia, an assistant professor at Harvard University.

    “In recent years, featuring wealthy people relaxing by the pool or on a yacht (游艇), playing tennis or skiing and hunting are being replaced with advertisements featuring busy individuals who work long hours and have very limited leisure time,” he said. “Displaying (how busy you are at work) and a lack of leisure time operates as a visible signal of status in the eyes of others.”

    The researchers pointed out that the Wall Street Journal's 2016 advert campaign featured celebrities (名人) complaining about their busy lives, with the slogan (标语). “People who don't have time, make time to read the Wall Street Journal.”

    The report, which was published in the Journal of Consumer Research, also found that brands that marketed themselves as timesaving were becoming increasingly high-status, because of the people who used them.

    According to the authors, this trend of humblebragging is due to people's shit of focus-they now value “the preciousness und scarcity (稀缺) of individuals" more than “the preciousness and scarcity of goods”.

    “Busy individuals possess desirable characteristics, leading them to be viewed as scarce and in demand,” the authors concluded.

    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.

    Here are some recommendations for tourists to choose from.

    Banff, Canada

    Banff, located in the Rockies, has a view of tall mountains, deep valleys and lakes, making it the first town to become part of the country's national parks. Tourists can enjoy its beauty by hiking, horse riding and boat trips. Banff was founded in 1883 while a railroad was in construction. It was the water springs that drew the engineers' attention to the place as a settlement. With such a fantastic view, it's no surprise that Banff hosts a number of cultural festivals.

    Lisbon, Portugal

    Lisbon is the capital of Portugal, with the warmest winters of any major European city.

    Belem Tower and Jeronimos Monastery are listed as UNESCO World Heritage Sites. The former was built in the 16^th century as a symbol of Portugal's Extraordinary Age and the latter is one of the greatest examples of the Portuguese late-Gothic style of architecture. The Lisbon Oceanaium is among Europe's finest aquariums. The Museu Calouste Gulbenkian is among the best museums in Europe containing priceless artworks covering 4000 years from ancient Egyptian times to the late 20^th century.

    Portland, US

    Portland is frequently recognized as one of the world's most environmentally-friendly cities because of its well-built pavements, large community of cyclists and convenient public transportation. Its climate is ideal for growing roses and it's called the “City of Roses”. Besides, the seaport is also known as a city of beer: it has the largest number of beer breweries（啤酒厂）of any city in the world. Today's Portland is better known for its music. It's called “the capital of karaoke” and “one of the most exciting music scenes” in the US.

    Bordeaux, France

    Bordeaux attracts tourists with its rich cultural heritage, especially its wealth of architectural treasures. Besides the Cathedral of Saint Andrew dating back to 12^th century, the Basilica of Saint Michael is another one of the city's UNESCO World Heritage Sites. It took 200 years to build from 14^th to 16^th centuries. Other significant buildings include the Grand Theater built in 1780 in the new Classical style and the Stone Bridge built in 1821.

    China has become the first country to successfully land a spacecraft on the far side of the moon. The Chang'e-4 probe (探测器) has also made the first lunar landing since 1972. It has the task of exploring the side of the moon that never faces the earth. The dark side of the moon is older and has a thicker surface than the visible side. It takes the moon as long to go around on its own axis (轴) as it does for one complete orbit around the Earth.

    The Chinese probe landed in a huge crater 2500 km in diameter and 13 km deep. The crater is one of the oldest parts of the moon and our solar system.

    Scientists hope to learn more about the geology of the far side of the moon. The craft has two cameras on board which will send images back to earth. It will also attempt to send signals to distant regions of space, something that cannot happen on earth because of too much radio noise.

    Chang'e-4 also has instruments on board to examine minerals as well as a container with seeds which will try to create a miniature (微型的) biosphere (生物圈).

Communication with the spacecraft is not easy. Images and other data must be transmitted to a separate satellite because no direct communication with the earth is possible.

    For China the Chang'e-4 mission is an important achievement, because the country has successfully done something no other nation on earth has. It wants to become a leading power in space exploration and has announced plans to send astronauts to the moon and set up its own space station.
