Five years ago, David Smith wore an expensive suit to work every day. "I was a clothes addict(有瘾的人)," he jokes. "I used to carry a fresh suit to work with me, so I could change if my clothes got wrinkled(有褶皱的)." Today David wears casual clothes (便装) to the office. He hardly ever wears a necktie. "I am working harder than ever." David says, "and I need to feel comfortable."

More and more companies are allowing their office workers to wear casual clothes to work. In the United States, the change from formal to casual office wear has been gradual. In the early 1990s, many companies allowed their employees to wear casual clothes on Friday. This became known as "casual Friday". "What started out as an extra one-day-a-week benefit for employees has really become an everyday thing." said business consultant Maisly Jones.

Why have so many companies started allowing their employees to wear casual clothes? "One reason is that it's easier for a company to attract new employees if it has a casual dress code." "A lot of young people don't want to dress up for work," says Owen Black, the owner of a software company, "so it's hard to hire people if you have a conservative (保守的) dress code." Another reason is that people seem happier and more productive when they are wearing comfortable clothes. In a study conducted by Levi Company, 85 percent of employers said that they believe that casual dress improves employee morale (心境, 士气). Only 4 percent of employers said that casual dress has a negative influence on productivity. Supporters of casual office wear also argue that a casual dress code helps them save money. "Suits are expensive, if you have to wear one every day," one person said. "For the same amount of money, you can buy a lot more casual clothes."

    A mouse looked through the hole in the wall to see the farmer and his wife open a pckage, and he was devastated to discover it was a mousetrap. Returning to the farmyard, he warned everyone. “There is a mousetrap in the house! There is a mousetrap inthe house! There is a mousetrap inthe house! ”

    The chicken raised her head and said, “Thanks for your warning. Mr. Mouse, but why should I be bothered by a mousetrap?” the pig sympathized, but said, “Wow, Mr. Mouse, I'm sorry for you I can tell this is a great concern to you, but it is none of my business.” The mouse returned to the house, head down and depressed, to face the farmer's mousetrap alone.

The very night a sound was heard throughthe house—-like that of a mouse trap catching its prey. The farmer's wife rushed to see what was caught. In the darkness, she did not see it was a snake whose tailwas caught by the trap, and it bit her. The farmer rushed her to the hospital and she returned home with a fever.

    The farmer killed the chicken to make fresh chicken soup for his wife, but her sickness continued. Frineds and neighbors came to visit her, and to feed them, the farmer butchered the pig. Then she died. So many people came for her funeral that the farmer had the cow cooked to provide enough meat for all of them.

    The mouse looked upon it all from his hole in the wall with great sadness.

    Robots are increasingly being developed to think and act like humans. But it is difficult for engineers to create humor (幽默) in machines. Computer scientists have hoped to help them understand humor. But they failed again and again. Why is it so difficult?

    Kiki, a computer language expert (专家), studies humor at a university. "Most robots are powered by artificial intelligence (人工智能AI). But AI will never understand jokes like humans do." He said, "The main problem is that AI system doesn't have the sense of humor."

    Other experts agree that context (语境) is very important to understand humor, both for humans and robots. In one project, Tristan Miller, a computer scientist, studied more than 10, 000 puns. Puns are a kind of joke that uses a word with two meanings. For example, you could say, "Balloons (气球) do not like pop music." The word "pop" can be a way of saying popular music, or "pop" can be the sound a balloon makes when it explodes(爆炸). "A robot might not understand the joke because it doesn't know the meaning of the puns." Miller said.

    Although it's difficult, some scientists say there are good reasons to keep trying to teach humor to robots. It can make machines understand humans better and serve humans better. And it can also help them to think more like humans.

    But other scientists don't think it's a good idea to teach humor to robots. They may find humor, but they may use it in a wrong way. Maybe bad Al will start killing people because it thinks it is funny. Besides, it may make some people feel not safe. The comedians(喜剧演员) may lose their jobs when the robots can understand humor.

From a young age, Michael Platt loved two things: the Rev. Martin Luther King, Jr. and cupcakes. He imagined ways he too could fight for justice. He memorized figures about income inequality and childhood hunger. But he also spent afternoons at his home computer, amazed by YouTube bakers who made perfect cupcakes.

When his parents gave him a pair of Toms shoes for Christmas three years ago, Michael saw a way to connect his twin passions. At age 11, he founded a bakery that operates on the Toms one-for-one model: For every cupcake, cake or cookie that Michael sells, he donates another to the homeless and hungry. Twice a month, he heads to locations to pass out goodies. Michael, now 13, said he especially enjoys handing out cupcakes to kids.

"I know I like cupcakes, but also cupcakes are part of a child's childhood so they should get them," said Michael, noting that he always eats one with whippedicing (打发的糖霜) on his birthday.

Michael calls his baking business Michaels Desserts. He left out the apostrophe (撇号) as a reminder that he is baking for others, not himself. "I always wanted to have a purpose for what I do." he said. "It's all about helping people— not just having a purpose for yourself, but thinking about, 'How does this touch other things? "

When he started the bakery, he knew that he wanted his business to do more than make money. That's why the intention of Michaels Desserts is fighting hunger and giving back, which Michael accomplishes through his giveaways. Michael hopes his cupcakes inspire others to work for social equality.

Sometimes, Michael admits, he grows tired of being in the kitchen. Then he remembers the homeless boy he met once while handing out cupcakes. A couple of days afterward, the boy's father messaged Michael on Facebook to say that his son, encouraged by Michael's example, now desired to become a baker.

"That inspired me," Michael said. He smiled and looked down.
