You're out to dinner. The food is delicious and the service is fine. You decide to leave a big fat tip. Why? The answer may not be as simple as you think.

    Tipping, psychologists have found, is not just about service. Instead, studies have shown that tipping can be affected by psychological reactions to a series of different factors from the waiter's choice of words, to how they carry themselves while taking orders, to the bill's total. Even how much waiters remind customers of themselves can determine how much change they pocket by the end of the night.

    “Studies before have shown that mimicry(模仿) brings into positive feelings for the mimicker,” wrote Rick van Baaren, a social psychology professor. “These studies show that people who are being mimicked become more generous toward the person who mimics them.”

    So Rick van Baaren divided 59 waiters into two groups. He requested that half serve with a phrase such as. “ Coming up !” Those in the other hall were instructed to repeat the orders and preferences back to the customers. Rick van Baaren then compared their take-home pay. 'The results were clear—it pays to mimic your customer. The copycat(模仿者) waiters earned almost double the amount of tips to the other group.

    Leonard Green and Joel Myerson, psychologists at Washington University in St. Louis, found the generosity of a tipper maybe limited by his bill. After research on the 1,000 tips left for waiters, cabdrivers, hair stylists, they found tip percentages in these three areas dropped as customers' bills went up. In fact, tip percentages appear to plateau(稳定期) when bills topped $100 and a bill for $200 made the worker gain no bigger percentage tip than a bill for $100.

    “That's also a point of tipping,” Green says. “You have to give a little extra to the cabdriver for being there to pick you up and something to the waiter for being there to serve you. If they weren't there, you'd never get any service. So part of the idea of a tip is for just being there.”

    Throughout the past few years, I have tried to give myself to others. I have bounced around to find where I truly fit in. I found my place while I stayed in Guatemala, an orphanage(孤儿院), with the children living there. Through hearing many stories of their lives, I was moved to tears and started question my living ways and gave up everything that wasn't essential: makeup and any other sort of luxury(奢侈品). I lived like they did. It was the most relaxing feeling in the world.

    When at Nuestros Pequenos Hermanos, we were given the task of creating a pig pen. At first, I thought it should be easy. After arriving at the area where the pig pen should be, we saw a hill. We were told to uproot the weeds as well as level the entire area. Looking at it, we felt 'it would be impossible. On my own faith journey, I have felt this type of doubt before. The “hole”, as we referred to, is a symbol of my faith journey. It appeared to be an obstacle I could not overcome, but in the end I completed it with efforts. I feel this pig pen wasn't easy to create but was so rewarding to give.

    I've always struggled to be on a journey of faith, but I've never completely stepped foot onto the path until Guatemala. I've always tried to open my heart to everyone around me and give them my love. I feel as though I cut open my heart and share every bit of love 'I had with these orphans. There is one orphan named Ceto who will always remain very close to my heart. In Guatemala, I sponsor with thirty dollars a month, but it doesn't seem enough. I'll return there next summer and give more of my love for a whole month.

    When it was time to leave, I looked out of the window and saw not just ordinary children. Overall, the most significant accomplishment I made in Guatemala was stepping towards my own faith journey and not looking back.

    Once an old man rose early to read each morning. His grandson wanted to be just like his grandfather, so tried to emulate him every way he could.

    One day the grandson asked, “Grandpa, I try to read just like you do, but I don't understand most of it, and I forget whatever I do understand immediately I close the book. So what good is it for me to read?”

    The grandfather, who was putting coal on the fire, said, “Take this coal basket down to the river and bring me back a basket of water.”

    The boy did as told to, but the water leaked out before he could get the basket home.

    The grandfather laughed, saying, “You'll have to move a little faster.” This time he ran faster, but again the basket emptied. Out of breath, he decided it was impossible to carry water in a basket, and he went to get a bucket（桶）. But the grandfather said, “I want a basket of water instead of a bucket of water. You're just not trying hard enough.”

    The boy knew what he was trying to accomplish was impossible. However, he decided to show his grandfather a third time.

    The boy dipped the basket into the river and ran as hard as he could. With the empty basket, he gasped（喘气说）, “See Grandpa? It's useless!”

    “So you think it useless?” the old man asked. “Then look at the basket.” To his surprise, the boy found it washed clean of the dirty coal stains and now clean inside and out.

    “My child, that's what happens when you read the book. You might not understand or remember everything, but the words will change you inside and out. That is the work of reading in our lives.”

    Have you ever lost your car on a parking lot? You don't have a clue where your car is after shopping. Then you start walking around clicking on your car keys so the alarm goes off. It can be annoying, especially on a hot sunny day.

    No, you needn't install (安装) an expensive GPS system to keep track of your car. That's too expensive. You would need to pay a monthly fee to use it.

    But is there a way to track your vehicle without spending a fortune? Yes, now there is! A California-based company has created a tiny device that works with your smartphone, which could be exactly what you're looking for!

    What is it?

    It's called TrackR. It is a state-of-the-art tracking device the size of a coin. It's changing the way we keep track of the important things in our lives.

    How does it work?

    It's easy! Install the free TrackR app on your smartphone, connect the app to your device and you're ready to go! Simply attach TrackR to whatever you want to keep an eye on. The entire process of setting it up only takes 5 minutes or less.

    You can attach it to your keys, briefcase, wallet, your latest tech gadgets and anything else you don't want to lose. Then use the TrackR app to locate your missing item in seconds.

    If you forget where you have parked your car, pull out your smartphone and open the TrackR app. Tap on the “find device” button on the screen and the app will tell you the exact spot of the last known location of the TrackR.

    What else can I do with TrackR?

    The device is small and unnoticeable enough that you can attach it to your pet. Put it on their collar, and the issue of searching for them when they run away to nearby places will be over! You'll never waste a minute searching the whole house for it.

    TrackR even comes with a double-sided glue (胶水) so you can stick it to your laptop or under your bike seat. Track down and punish the thieves who steal your expensive things!

    How much does it cost?

    You're probably thinking that this device is very expensive. False! TrackR only costs $29! That's a small price to pay for peace of mind, isn't it?

    You can buy it directly from the company's website by clicking here https: //buy. thetrackr. co/gu/special- offers/15/.

    Today the Nobel Prize in Literature awarded journalist Svetlana Alexievich approximately $970,000 in recognition of a lifetime of excellence. The 67-year-old author of Voices From Chernobyl and War's Unwomanly Face was praised by the Swedish Academy "for her polyphonic(复调式的) writings, a monument to suffering and courage in our time."

    Prizes like the Nobel inspire much expectations before the announcement. People give their best guesses as to who will win, look back on past winners, and even place bets as if spectators at a Derby(赛马会).

    Literary prizes reward artistic brilliance. They help writers earn a decent living. But is the public's fascination with prize-winning authors healthy? Our impulse seems to increasingly contribute to a culture of turning authors into celebrities, where readers follow the author instead of the book.

    A story should stand on its own, as a considered, complete book, without biographical information from author. It's an idea perhaps best conveyed in Roland Barthes's 1968 essay The Death of the Author. "The image of literature to be found in contemporary culture is arbitrarily centered on the author, his person, his history, his tastes, his passions."

    Nearly 50 years later, a few still agree. "I believe that books, once they are written, have no need of their authors," New York Times bestselling author Elena Ferrante once wrote. "If books have something to say, they will sooner or later find readers; if not, they won't, "she continued. "True miracles are the ones whose makers will never be known."

    ①But the rules for submission for the Man Booker International Prize, for example, strongly encourage authors to "make themselves available for publicity". And the foundation behind the National Book Award requires finalists to participate in their "website-related publicity".

    ② In 2007, a reporter who showed up uninvited at Doris Lessing's house was the first to inform her that she had been awarded the Nobel Prize in Literature. Today the Twitterati came knocking on Alexievich's digital door hour before the award was even official. To be considered for a prize is to be a public figure.

    ③ Harry Potter series author J. K. Rowling, with over 5.6 million Twitter followers, has actively addressed readers through public appearances and social media, revealing much more than we could have imagined when we closed the final Harry Potter book. We now know the house Harry's children will be sorted into, that Dumbledore is gay," Voldemort" is actually pronounced with a silent "t", and a whole host of the other minor and major details about the backstory of the characters.

    The magical world Rowling created in her books—a relatively tight mystery with well-laid clues that led to a satisfying conclusion, which had to prove their merits to the reader based on an internal logic—is being unraveled by her own hand.

    ④ Of course, public attention also has very important benefits for authors. For three months after receiving the 2011 Pulitzer Prize in fiction, Jennifer Egan's A Visit from the Goon Squad sold about triple its print sales from before the prize, Publishers Weekly reports. On Oct. 5, 2010, in the first FT/Oppenheimer Funds Emerging Voices Awards, as Nigerian-born Chigozie Obioma accepted the prize for fiction with an easy smile, his excitement was appreciable. Given the cash prize of $40,000 for each winner, it's hard to downplay the importance of such an honor. Such awards bring necessary visibility and funding to writers facing a literary landscape dominated by white men.

    But our culture of celebrity is often too wrapped up in the way we read: How might the meaning of a work change if the author really didn't grow up in a poor neighborhood, or if he or she was abused in childhood? Readers studied the author's life as if it were the key to interpreting his or her novels.

    Behind our fascination is the question that drives all such questions: What did the author intend? By all means, let us praise brilliant work and in doing so trust that the author has already told us enough, and that the story he or she meant to tell ended with the final page.

Doing crosswords(纵横字谜) is a fun way to kill the time and can also be educational. Difficult crosswords may leave you confused as you have no ideas on how to solve them sometimes. To perform well in this game, you need to have enough knowledge of different fields. If you are unable to do them and you have access to the answers, it is not generally considered cheating to look up an answer or two. However, in some cases, it does not follow the rule.

A crossword should not include someone else's answers, so even a quick look at a fellow student to complete a crossword would not be fair. Generally, you wouldn't have access to the answers.

Additionally, some crossword competitions should not be connected with cheating. Again, in such a situation, you usually won't have access to the answers. Turning to the Internet or referring to(查阅) any books of crosswords for answers is also unfair, since some people will complete the crosswords strictly with their own knowledge.

If you are not in a competitive environment, the check of a word can actually be an opportunity to learn how to become better at crosswords. Through looking up the answers (Although sometimes considered as cheat.), you can memorize whatever facts or word definitions (定义) you must look up. This will help you avoid the need to cheat in the future.

Some argue that cheating on crosswords is always wrong, and you're only cheating yourself if you are looking up the answers. It could be argued instead that cheating on crosswords that are done for fun or enjoyment can actually be an opportunity to benefit yourself because you're learning something new. Just don't forget to mention that you actually did cheat a little. Being honest is of great importance both to you and the other competitors.

It can be helpful to buy books of crosswords that have several different difficulty levels. If you are new to doing crosswords, you might want to put off working on crosswords until you are more confident in your skills.
