The first living creatures to travel in space were the dogs of the Soviet Unions space program.Beginning in 1951 dogs flew aboard sub－orbital flights to the height of 63 miles and higher.They helped to test the equipment that would later be used by humans.The first pair of dogs to fly，on July 22，1951，were named Tsygan and Dezik.

     Space dogs would make history on November 3，1957.On this date，just one month after the historic launch of the world's first artificial satellite，Sputnik，the Soviet Union shocked the world again by launching Sputnik 2.This satellite contained the first living creature to travel in space，a dog named Laika.Laika was to have orbited for a week or more until her food and oxygen ran out.In fact，Laika lasted only hours in orbit before over heating in her capsule(太空舱) took her life.

     That next step，occurred in August 1960，when the dogs Belka and Strelka made 18 orbits of earth and returned alive.Like Laika before them，they became distinguished ， featured in newspapers and magazines around the world.

     Six more orbital dog flights over the next eight months further tested the equipment necessary for humans to follow in the dogs' footsteps.That historic event happened on April 12，1961，when Yuri Gagarin became the first human to travel in space.

     The role of the space dogs had proven important in advancing the exploration of space.But，they would make one final flight.In 1966，traveling aboard the Cosmos 110 satellite，the dogs Ugolek and Veterok spent 22 days in orbit.Once again dogs led the way.Humans would not achieve a space flight that long for eight more years，in Skylab 2.

    “Have a nice day!” may be a pleasant gesture or a meaningless expression. When my friend Maxie says “Have a nice day!” with a smile, I know she sincerely cares about what happens to me. I feel loved and secure since another person cares about me and wishes me well.

    “Have a nice day. Next!” This version(版本) of the expression is spoken by a salesgirl at the supermarket who is rushing me and my groceries out the door. The words come out in the same tone with a fixed procedure. They are spoken at me, not to me. Obviously, the concern for my day and everyone else's is the management's attempt to increase business.

    The expression is one of those behaviors that help people get along with each other. Sometimes it indicates the end of a meeting. As soon as you hear it, you know the meeting is at an end. Sometimes the expression saves us when we don't know what to say. “Oh, you just had a tooth out? I'm terribly sorry, but have a nice day.”

    The expression can be pleasant. If a stranger says “Have a nice day” to you, you may find it heart-warming because someone you don't know has tried to be nice to you.

    Although the use of the expression is an insincere, meaningless social custom at times, there is nothing wrong with the sentence except that others who speak it without thinking may not really care about my day. But in a strange and comfortable way, it's nice to know they care enough to pretend they care when they really don't care all that much. While the expression may not often be sincere, it is always spoken. The point is that people say it all the time when they like.

    What do butterflies have in common with the human spirit? Meet Maggie, a middle-aged wife and mother who was about to find out.

    Maggie wasn't rich like a millionaire or poor in a manner of being homeless. She was living an average comfortable life. It was made even better when a baby girl came her way. She and her husband made sure their daughter had her needs met and they were still able to take a yearly vacation by the beach.

    Maggie was a partner in her husband's business. They both had a different set of duties and everything was in balance. One day a severe blow came to her husband's business, and over a three-year period the business dropped out of sight. Her husband had to totally reinvent himself and was eager to start a new business. She was happy for him and supported him fully, but still the money was not coming in.

    Maggie began to feel guilty that she wasn't contributing with any kind of income. She began job-hunting and found filling out applications somewhat difficult, especially the part asking for job references. She was self-employed with her husband for almost 20 years, which seemed to mean nothing as she was never called for an interview.

    When she was job-hunting her mom became more ill than she had been and ended up in the hospital for a week. Once Maggie's mom returned home she became her mom's helper one day a week. She did everything that her mother was not able to do any more. Of course her mom would pay her for her lime and labor but she still felt she needed to find another source of income.

    One of the first applications she had filled out finally came through. She passed the interview and was told she was exactly what they were looking for. Although it was only part-time it was exactly what she wanted. It was important for her to be home when her daughter arrived home from school.

    Within a few weeks, though, she received an e-mail saying that the company had changed the job into a full-time position so that she was not qualified. Maggie felt betrayed and felt she had been lied to. That evening she was alone at home. She welcomed the aloneness and wanted to put herself in the bathtub to kill the lonely time.

    As she knew she would, Maggie began to cry, softly at first just from the sharp pain of being rejected. Three long years of struggle had finally overwhelmed her.

    When she was able to cry no more, she became worn out and gave up. It was at that moment that a silent idea came to her: why not offer elderly people home care assistance? Using another talent for computers she printed off some flyers and cards and distributed them to her church, grocery stores and even placed a small ad in the newspaper. Within a week she had procured two new customers. Now, even though she's not a CEO of a major company she feels happy and productive again.

    Before a butterfly can come out of its chrysalis (茧) it has to go through a lot of struggling. Each time it pushes out to escape, acids are being removed from its wings. If someone were to come along and break the chrysalis open for it then the butterfly would die from those acids. Actually the struggle is necessary for the butterfly to survive. Then in the stillness, when the struggle is over, the butterfly can come out and share its beauty with the world.

    We as humans are not any different.

    Long before iPhone, the cigarette was the companion of choice for restlessness. And long before Facebook and WeChat, it was tobacco that promised to better your social life. Now, quitting smartphones has become the new quitting smoking.

    Of course, technology does not yellow your teeth, cause disease or lead to cancer. But some individuals are so concerned that device addiction is damaging their mental health. In order to reduce their dependence, even in Silicon Valley, people are turning off the messages that constantly buzz for their attention, banning smartphones from the bedroom and, curiously, changing the colors on their screens to a less tempting scale of gray.

    The big tech companies will have to work out how to respond to this new generation of quitters. Facebook is the first to go public with its attempt, hoping its recent move can make the social network more homely.

Last year the tech industry got a bad name —Big Tech—with unfortunate echoes of other industries that have faced fierce opposition, including Big Tobacco. Like them, the tech industry has to reduce concern from a new generation of activist shareholders （股东） that are questioning its role in the world. These campaigns are never as fierce as those faced by Big Tobacco. In the 1990s, socially responsible investors refused to put money in tobacco stocks.

    It is far difficult for investors to challenge Big Tech and hard to separate the good these companies do in the world-connecting old friends and giving space for people to share their ideas-from the bad. In the meantime, stopping using technology remains problematic. In The World Without Mind: The Existential Threat of Big Tech, Franklin Foer argues that tech should be seen in a similar way to junk food: a convenience that some reject for more continuing nutrition.

    So we need to do more to turn the tide. In the same way that public service announcements made smoking around your children taboo （禁忌）, we can warn parents against losing themselves in their smartphones while taking care of kids. We can also create no-smartphone zones at dinner. Eventually smartphones could be banned from all public places and help us give our attention to the people around us instead.

It should be one of the main goals in today's society to reduce plastic consumption.Though many believe recycling will solve the problem,and continue using plastic,it's actually the opposite.In 2013,254 million tonnes of trash was produced in the US alone,and only around 30% was recycled.This means the rest ended up in a landfill and will stay there for up to 1,000 years.

Now Asian countries,including Vietnam and Thailand,are looking for new ideas to avoid plastic.One of those ideas was a new,eco-friendly way to pack their goods by avoiding plastic packaging.One of Perfect Homes Chiangmai's team members noticed a creative way to reduce plastic that a supermarket called Rimping Supermarket was using.Little did he know that people all around the world would absolutely love this idea."I just entered to get a few items while we were waiting to sign some contracts with our lawyer,who was delayed.When I noticed the vegetables wrapped in banana leaves,I simply liked the idea.So I took a few pictures and posted them online," he said.

With more than 3.5 million views and over 17 thousand shares,the idea became something people can encourage more supermarkets to implement(实施).

Some have noticed that not everything on the shelves is completely plastic-free to which the supermarket responded that they are taking one step at a time,but it's not that easy.Many products come to the supermarkets pre-packaged and many companies are interested in wrapping their produce in plastic since it is the cheapest and the easiest option.

It's now up to the shoppers to show the supermarket which they prefer.If everyone opts for the banana leaf packaging,they will probably stop stocking the items in plastic.

Is forgiveness against our human nature? To answer our question, we need to ask a further question: What is the essence of our humanity? For the sake of simplicity, people consider two distinctly different views of humanity. The first view involves dominance and power. In an early paper on the psychology of forgiveness, Droll (1984) made the interesting claim that humans' essential nature is more aggressive than forgiving allows. Those who forgive are against their basic nature, much to their harm. In his opinion, forgivers are compromising their well-being as they offer mercy to others, who might then take advantage of them.

The second view involves the theme of cooperation, mutual respect, and even love as the basis of who we are as humans. Researchers find that to fully grow as human beings, we need both to receive love from and offer love to others. Without love, our connections with a wide range of individuals in our lives can fall apart. Even common sense strongly suggests that the will to power over others does not make for harmonious interactions. For example, how well has slavery worked as a mode of social harmony?

From this second viewpoint of who we are as humans, forgiveness plays a key role in the biological and psychological integrity of both individuals and communities because one of the outcomes of forgiveness, shown through scientific studies, is the decreasing of hatred and the restoration of harmony. Forgiveness can break the cycle of anger. At least to the extent the people from whom you are estranged accept your love and forgiveness and are prepared to make the required adjustments. Forgiveness can heal relationships and reconnect people.

As an important note, when we take a Classical philosophical perspective, that of Aristotle, we see the distinction between potentiality and actuality. We are not necessarily born with the capacity to forgive, but instead with the potential to learn about it and to grow in our ability to forgive. The actuality of forgiving, its actual appropriation in conflict situations, develops with practice.
