“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.

    Every day, a homeowner in Pennsylvania is reminded of a mistake he made 13 years ago. At around 8 in the evening, his peaceful house comes alive with the noise of an alarm clock he dropped into the wall over ten years ago. It's been stuck in the wall ever since.

    13 years ago, Jerry Lynn wanted to make a hole through his living room wall, so he could pass the television cable (电缆)through it. He didn't want to destroy any pipes in the wall, so he came up with a good idea to make sure that he was drilling(钻孔) in an empty place. He took his alarm clock, tied it to a string(线) and set it to go off in 10 minutes. Then he lowered it into the wall, and waited for it to ring. His goal was to drill a hole in a safe place near the place where the ringing was coming from, making sure that there was nothing to pass through there. It all went smoothly until the alarm clock fell into the wall.

The man didn't get back the alarm clock, but thought it would probably run out of battery(电池)in several months, so he wasn't too worried about it. But 13 years later, the alarm clock still rings every day.

    As you can imagine, Jerry and his wife have gotten used to the ringing living room wall, but it can still surprise  guests. So Jerry decides to pull down that wall, just to stop that boring thing, though after putting up with it for 13 years, he think it will be a pity. He says, “I've never herd of a clock battery lasting that long and my friends think it may be interesting to see how long it will keep ringing for.”

    Exactly five years ago, on New Year's Eve, I was invited to a children's ball by a man high up in the business world, who had his connections, his circle of acquaintances, and his close friends. So it seemed as though the children's ball was merely an excuse for the parents to come together and discuss matters of interest to themselves, quite innocently and casually.

    I was an outsider, and, as I had no special matters to air, I was able to spend the evening independently of the others. There was another gentleman present who like me had just stumbled upon (偶然发现) this affair of domestic happiness. He was the first to attract my attention. His appearance was not that of a man of noble birth. He was tall, rather thin, very serious, and well dressed. Obviously he had no heart for the family celebration. The instant he went off into a corner by himself the smile disappeared from his face, and his thick dark brows knitted into a frown(皱眉). He knew no one except the host and showed every sign of being bored to death, though bravely keeping the role of thorough enjoyment to the end. Later I learned that he was a provincial, had come to the capital on some important business, had brought a letter of recommendation to our host, and our host had taken him under his protection, not at all with love. It was merely out of politeness that he had invited him to the children's ball.

    They did not play cards with him. They did not offer him cigars. No one entered into conversation with him. Possibly they recognized the bird by its feathers from a distance. Thus, my gentleman, not knowing what to do with his hands, was compelled(迫使) to spend the evening stroking (抚摸) his whiskers(胡须). His whiskers were really fine, but he stroked them so eagerly that one got the feeling that the whiskers had come into the world first and afterwards the man in order to stroke them.

    A bright yellow “M” tells you that it's a McDonald's restaurant; we also associate the cheerful theme tune “I'm Lovin' It” with the famous US fast food.

A brand's music has a similar effect on its customers as its logo. “It appeals directly to the heart, where consumers' decisions are really made,” wrote Marketing Week.

This is probably why companies from around the world have recently focused more on building a “sonic (声音的) identity”.

    An example is the software company Tencent QQ. Since 2014, this Chinese company has been trying to trademark (申请商标权) its “Di-Di-Di-Di-Di-Di” notification sound. The trademark was finally approved on Nov 15, which means that Tencent's “Di-Di-Di-Di-Di-Di” notification sound is now protected by law and can only be used by QQ.

    Sound and music can also help tell stories. In Game of Thrones (《权力的游戏》) there are so many characters that it is difficult to memorize them all. So, they wrote melodies (旋律) specific to each family. The result is that characters do not only look familiar, but sound familiar too.

    “I think a huge reason why sound inspires action is that, on an unconscious level, we are always listening,” Lauren Nagel, executive creative director at Pandora Media, told GeoMarketing. “You can close your eyes, but you can't shut your ears.”

    Measles (麻疹) is only found in human beings. There is a highly effective and safe vaccine (疫苗) for the disease. So, in theory, measles could be destroyed.

    Yet the number of measles cases is on the rise.

    The World Health Organization (WHO) reports that, in the first three months of 2019, the number of cases is three times higher than it was last year. Africa alone has had a 700 percent increase compared to last year.

    The Democratic Republic of Congo reported 67,000 measles cases and 901 measles-related deaths in 2018. This year, WHO officials have noted more than 40, 000 suspected measles cases in the country. That number includes 284 measles-related deaths in the first weeks of 2019. Between September 2018 and February 2019, Madagascar reported over 67, 000 measles cases, including 828 deaths.

    Dr. Fauci, who directs the National Institute of Allergy and Infectious Disease in the USA, said that one in 10 children who get infected with measles will get an ear infection that could cause deafness. One in 20 would get pneumonia. One in a thousand would get brain swelling, and one to three per thousand would die. To say that measles is a slight disease is completely incorrect.

    Walter Orenstein is with the Emory University Vaccine Center in Atlanta, Georgia. He has spent his life working to end measles. Orenstein says possible effects of the disease are worse in poor countries. In those countries children are already at greater risk. They may be malnourished (营养不良的). They may have damaged immune systems. They may be underweight and may have no access to health care so measles is a big killer, he said.

    You have a 90 percent chance of getting measles if you have not been vaccinated and you come in contact with someone who has it. Dr. Rebecca Martin is the Director of the Center for Global Health at the U.S. Centers for Disease Control. She is working to remove measles from Africa completely. It is very infectious. It will find nearly everybody who is not protected against measles, Martin said.

    Health experts advise patients to get two treatments of the measles vaccine. U.S. health officials say educating parents about both the disease and the vaccine is an important step in stopping the spread. Equally important is making vaccination a top goal of health systems worldwide.
