In today's households where both parent go to work and kids have busy schedules with school homework and many afternoon activities, finding time for a gathering at the table seems all but impossible. Yet, studies have shown time and again that eating together has multiple benefits for family members, especially children.

    According to reports issued by the National Center on Addiction and Substance Abuse at Columbia University(CASA), children who eat more with their family are at lower risk of developing poor eating habits, weight problems or alcohol dependencies. They tend to perform better academically than those who frequently eat alone. Family meals came into American life in the mid-20^th century. In the 60's and 70's, social, economic and technological changes quickly dissolved the short-lived way of family meals. Restaurant visits, take-out and TV dinners have since become the norm.

    There are indicators, however, that the old customs are coming back. According to the latest CASA reports, 59% of surveyed families said they ate diner together at least five times a week, a significant increase from 47% in 1998. Whatever drives this trend, it is a development that should be welcomed.

    Eating together as a family is not just about food and nutrition. It is about teaching them how to become members of their society and culture. Food as become so easily and cheaply available that we no longer appreciate its significance. We have to rediscover its importance and its value. Sharing a meal with loved ones should be considered a special event, which can almost take on the form of a ceremony, as it was practiced by our ancestors for whom finding food was a constant struggle.

    Of course, there is no guarantee that the simple act of eating at home surrounded by family may make children more virtuous or socially more responsible. But it can lay the groundwork for a lot of things that point them in the right direction.

    Most people agree that honesty is a good thing. But does Mother Nature agree? Animals can't talk, but can they lie in other ways? Can they lie with their bodies and behavior? Animal experts may not call it lying, but they do agree that many animals, from birds to chimpanzees, behave dishonestly to fool other animals. Why? Dishonesty often helps them survive.

    Many kinds of birds are very successful at fooling other animals. For example, a bird called the plover sometimes pretends to be hurt in order to protect its young. When a predator（猎食动物）gets close to its nest, the plover leads the predator away from the nest. How? It pretends to have a broken wing. The predator follows the "hurt" adult, leaving the baby birds safe in the nest.

    Another kind of bird, the scrub jay, buries its food so it always has something to eat. Scrub jays are also thieves. They watch where others bury their food and steal it. But clever scrub jays seem to know when a thief is watching them. So they go back later, unbury the food, and bury it again somewhere else.

    Birds called cuckoos have found a way to have babies without doing much work. How? They don't make nests. Instead, they get into other birds' nests secretly. Then they lay their eggs and fly away. When the baby birds come out, their adoptive parents feed them.

    Chimpanzees, or chimps, can also be sneaky. After a fight, the losing chimp will give its hand to the other. When the winning chimp puts out its hand, too, the chimps are friendly again. But an animal expert once saw a losing chimp take the winner's hand and start fighting again.

    Chimps are sneaky in other ways, too. When chimps find food that they love, such as bananas, it is natural for them to cry out. Then other chimps come running. But some clever chimps learn to cry very softly when they find food. That way, other chimps don't hear them,  and they don't need to share their food.

    As children, many of us learn the saying "You can't fool Mother Nature." But maybe you can't trust her, either.

    It isn't often that zookeepers call on craftsman for help. But cold weather at the Wildlife SOS Elephant Conservation and Care Center in northern India was putting elephants at risk. So the center's staff joined forces with locals to find a creative way to keep the animals warm. Now the elephants are stepping out in style, thanks to volunteers who made use of their crafting talents to knit (编织) enormous sweaters to protect the animals.

    Wildlife SOS is a conservation group that has been taking action against animal cruelty and saving wildlife in danger since 1995. Their Elephant Conservation and Care Center is devoted to rescuing the large animals from abuse in circuses, illegal dealing, and other circumstances where they have been ignored or treated with extreme cruelty. There are currently 20 elephants living at the center, and the staff hope to take in 50 more of the creatures this year.

    Because most of the elephants housed at the center are recovering from injuries or are elderly and weak, they are particularly vulnerable to cold temperatures. When the staff reported near-freezing nighttime temperatures in the winter, volunteers from surrounding villages began knitting enormous sweaters to keep the elephants warm. The monumental sweaters are large enough to cover the elephants' backs, bellies, and legs.

    Making the sweaters is a big undertaking—each one takes approximately four weeks to create, with volunteers working together on the enormous clothes. Local villagers have already made sweaters for three of the 23 elephants on their own, each with a unique pattern and color.

    If you're also looking for something happy and heartwarming, this is it. The elephants usually wear blankets to keep warm during colder months and you can purchase a blanket for an elephant on the Wildlife SOS website.

    Smoking is harmful. But as soon as you quit the habit, everything will be OK, right?

    Wrong

    New research has found that even if you give up smoking, the damage it has done to your genes(基因) will stay there for a much longer time. In the research, a team of US scientists studied the blood of 16,000 people. Among them, some were smokers, some used to smoke, and the rest were non-smokers. Scientists compared their genes and found that more than 7,000 genes of smokers had changed—a number that is one-third of known human genes.

    According to NBC News, both heart disease and cancer are caused by genetic changes. Some people may have had the changes when they were born, but most people get them in their day-to-day lives while doing things like smoking.

    When you stop smoking, a lot of these genes will return to normal within five years.

    This means your body is trying to heal (治愈) itself of the harmful effects of smoking. But the changes in some of the genes stay for longer. They can stay for as long as 30 years. It's almost like leaving a footprint on wet cement (水泥)—it will always be there, even when you've walked away and when the cement becomes dry.

    Although the study results may make people unhappy, there is a bright side: the findings could help scientists invent medicine to treat genetic damage caused by smoking or find ways to tell which people have heart disease or cancer risks.

    Each year, hundreds of thousands of wild animals around the world are killed in trophy hunting—the organized shooting of animals for pleasure. The hunters then bring parts of the animal home with them as their "trophy" to remember the hunting.

    Trophy hunters pay big money to kill animals. Some of the money goes to helping wildlife protection. Trophy hunting also attracts business, which encourages people to preserve land and breed(饲养) animals that would otherwise be endangered. Cathy Dean, head of the Save the Rhino Charity, says that at the start of the 1900s there were only 50–100 southern white rhinos. Now, there are around 18,000. This is partly because some of them were raised specially for trophy hunting.

    But things don't usually go on one way. According to WWF, elephant populations have fallen from 1.3 million to just over 400,000 since the 1980s. Over the same period, hunters from around the world have taken home more than 100,000 African elephant trophies. Trophy hunting is not illegal(非法的) but unfair on the animals. In 2015, Cecil the lion was shot by a US trophy hunter. Cecil was a beloved lion in Zimbabwe, Africa. Cecil was lured with bait(诱饵), shot with an arrow and struggled in blood for more than ten hours before his hunters tracked and finished killing him. His son, Xanda, met a similar fate two years later.

    Cecil's death caused worldwide outrage and protests(反抗) against trophy hunting. Countries including Australia, France and the Netherlands banned(禁止) the import of lion trophies—they stop hunters from being allowed to bring home parts of the animal they kill. They believe that people will stop trophy hunting because the activity might lose its attraction if hunters can't bring their trophies home.

    The UK Government said that it would consider a ban on trophy-hunting imports by 2017, but no action had been taken. In April 2019, a letter by protesters against trophy hunting was sent to the UK government asking to ban trophy-hunting imports. On 7 May, the official in charge of the environment, Michael Gove, said that the UK would not ban the imports for the time being. This left the world in a state of a shock. Hopefully the UK will place a ban on trophy-hunting imports, which would be an important message and inspire others to treat animals better. We're waiting for the day to come.

    In the United States, when one becomes rich, he wants people to know it. And even if he does not become very rich, he wants people to think that he is. That is what "Keeping up with the Joneses" is about. It is the story of someone who tries to look as rich as his neighbors.

    The expression was first used in 1913 by a young American called Arthur Momand. He told this story about himself. He began earning $125 a week at the age of 23. That was a lot of money in those days. And he was proud of his wealth(财富). He got married and moved with his wife to a very rich neighborhood outside New York City. When he saw that rich people rode horses, Momand went horseback riding every day. When he saw that rich people had servants, Momand and his wife also hired a servant and gave big parties for their new neighbors. It was like a race, but one could never finish this race because one was always trying to keep up. The race ended for Momand and his wife when they could no longer pay for their new way of life. They moved back to an apartment in New York City.

    Momand looked around him and noticed that many people do things just to keep up with rich lifestyle of their neighbors. He saw the funny side of it and started to write a series of short stories. He called it"Keeping up with the Joneses", because"Jones"is a very ordinary(普通的) name in the United States. "Keeping up with the Joneses" came to mean keeping up with rich lifestyle of the people around you. Momand's series appeared in different newspapers across the country for over 28 years.

    People never seem to get tired of keeping up with the Joneses. And there are"Joneses"in every city of the world. But one must get tired of trying to keep up with the Joneses because no matter what one does, Mr. Jones always seems to be ahead.
