Two things changed my life: my mother and a white plastic bike basket. I have thought long and hard about it and it's true. I would be a different person if my mom hadn't turned a silly bicycle accessory into a life lesson I carry with me today.

My mother and father were united in their way of raising children, but it mostly fell to my mother to actually carry it out. Looking back, I honestly don'tknow how she did it. Managing the family budget must have been a very hard task,but she made it look effortless. If we complained about not having what another kid did, we'd hear something like, “I don't care what so –and –so got for his birthday, you are not getting a TV in your room a car for your birthday a lavish sweet-16 party.” We had to earn our allowance by doing chores around the house. I can still remember how long it took to polish the legs of our coffee table. My brothers canno doubt remember hours spent cleaning the house .Like the two little girls growing up at the White House, we made our own beds (no one left the house until that was done) and picked up after ourselves. We had to keep track of our belongings, and if something was lost, it was not replaced.

It was summer and ,one day ,my mother drove me to the bike shop to get a tire fixed—and there it was in the window, White, shiny, plastic and decorated with flowers ,the basket winked at me and I knew —I knew—I had to have it.

       “It's beautiful,” my mother said when I pointed it out to her,” What a neat basket.”

       I tried to hold off at first, I played it cool for a short while. But then I guess I couldn't at and it any longer: “Mom, please can I please, pleaseget it? I‘ll do extra chores for as long as you say, I'll do anything, but I need that basket, I love that basket. Please, Mom .Please?”

         I was desperate.

      “You know,” she said, gently rubbing my back while we both staredat what I believes was the coolest thing ever,” If you save up you could buy thisyourself.”

“By the time I makeenough it'll but gone!”

      “Maybe Roger here could hold it for you,” she smiled at Roger, thebike guy.

“He can't hold it for that long, Mom. Someone else will buy it .Please,Mom, Please?”

      “There might be another way,” she said.

And so our paying plan unfolded. My mother bought the beautiful basket and put it safely in some hiding place I couldn't find. Each week I eagerly counted my growing saving increased by extra work here and there (washing the car ,helpingmy mother make dinner, delivering or collecting things on my bike that already looked naked without the basket in front).And then ,weeks later ,I counted ,re-counted and jumped for joy. Oh, happy day! I made it! I finally had the exact amount we'dagreed upon….

       Days later the unthinkable happened. A neighborhood girl I'd played with millions of times appeared with the exact same basket fixed to her shiny, new bike that already had all the bells and whistles. I rode hard and fast home to tell my mother about this disaster. This horrible turn of events.

And then came the lesson. I've taken with me through my life: ”Honey,Your basket is extra-special,” Mom said, gently wiping away my hot tears.” Yourbasket is special because you paid for it yourself.”

    We've considered several ways of paying to cut in line: hiring line standers, buying tickets from scalpers (票贩子), or purchasing line-cutting privileges directly from, say, an airline or an amusement park. Each of these deals replaces the morals of the queue (waiting your turn) with the morals of the market (paying a price for faster service).

    Markets and queues—paying and waiting—are two different ways of allocating things, and each is appropriate to different activities. The morals of the queue, “First come, first served, have an egalitarian (平等主义的) appeal. They tell us to ignore privilege, power, and deep pockets.

    The principle seems right on playgrounds and at bus stops. But the morals of the queue do not govern all occasions. If I put my house up for sale, I have no duty to accept the first offer that comes along, simply because it's the first. Selling my house and waiting for a bus are different activities, properly governed by different standards.

    Sometimes standards change, and it is unclear which principle should apply. Think of the recorded message you hear, played over and over, as you wait on hold when calling your bank: “Your call will be answered in the order in which it was received.” This is essential for the morals of the queue. It's as if the company is trying to ease our impatience with fairness.

    But don't take the recorded message too seriously. Today, some people's calls are answered faster than others. Call center technology enables companies to “score” incoming calls and to give faster service to those that come from rich places. You might call this telephonic queue jumping.

    Of course, markets and queues are not the only ways of allocating things. Some goods we distribute by merit, others by need, still others by chance. However, the tendency of markets to replace queues, and other non-market ways of allocating goods is so common in modern life that we scarcely notice it anymore. It is striking that most of the paid queue-jumping schemes we've considered—at airports and amusement parks, in call centers, doctors' offices, and national parks—are recent developments, scarcely imaginable three decades ago. The disappearance of the queues in these places may seem an unusual concern, but these are not the only places that markets have entered.

    With these tips you can finally get a solid night's sleep.

    Reserve Your Bed

    Get into bed just for sleeping. Avoid working, paying bills, reading, or watching television in bed. If you associate your bed only with sleep, you'll be more likely to fall asleep.

    Watch the Caffeine(咖啡因)

    Too much caffeine throughout the day can cause interrupted sleep. Limit yourself to two cups of tea, coffee, or cola, taken at least 6 hours before bedtime.

    Tap the Exercise Answer

    In a study from Stanford University School of Medicine, a group of 50- to 76-year-olds who had complained of sleep problems began proper exercise for about half an hour four times a week. Compared with a similar group of people who didn't exercise, the more active group slept an average of one hour more each night, took less time to fall asleep.

    Take a Bath

    Take a warm bath an hour or two before bed. Your body temperature will slowly drop after you get out of the tub（浴盆）, making you feel tired. Don't bathe right before bed, however, because it can briefly stimulate you enough to make it hard to fall asleep.

    Buy the Right Bed

    A bed that's too soft can cause poor sleep. Replace your mattress(床垫)if it's more than ten years old, and buy one that's as firm as you can tolerate but still comfortable.

    If 30 minutes go by and you haven't fallen asleep, don't lie in bed feeling frustrated. Get up and do something relaxing.

    The world is too big to take in all at once. To make sense and beauty of it, you have to look at a small part at a time.

    In using a camera, you choose a small part through he view finder. You move the camera, "framing" pictures until you see one that pleases you. Then-click! If you make a good choice, your picture will please others, as well as yourself.

    "Wherever you are," says photographer Ernst Haas, "you are surrounded by pictures. The trick is to recognize them." His photograph of a twist of barbed wire shows what he means.

    Mr. Haas tells us of ways to practice seeing. Make a simple frame of black cardboard. Take it out of the doors and look through it at everyday things, large or small, far away or near.

    At first you may see nothing to interest you. But soon pictures seem to leap (跳) at you through the frame. Oil floating on water makes a picture in rainbow colors. Three people on the steps of an old house form a picture that seems to tell a story.

    Did you notice such things before you used the frame? Perhaps not. But, with practice, you soon do not need its help. You see things as artists do. Everywhere, shapes and colors catch your eye. Your mind takes "snapshots (快照)" of their patterns. Then, if you wish, you can share what you see by taking a photograph or by making a drawing or a painting.

    Sometimes it's fun to "see small". Did you ever notice the design of the seeds in sliced bananas? Have you looked deep inside a lily? Or seen the starburst in the center of a wet ice cube?

    Do you see colors as they really are? When you paint tree trunks, you would make them brown or black. But tree trunks are really gray, purple, yellow-green—almost any color except brown or black!

    Do you notice detail? Doing so can be in many ways. Remembering what you see is often useful, too. Practice can help you.

    A trick for helping you to remember detail is the double take. Look—don't look—then look again.

    Ride-hailing apps and robot cars promise to change how we get around and the effects are already being felt. Traffic in New York is slowing down. Jams are common in Manhattan, especially in its business districts. Daytime traffic in the busiest areas now moves almost 20% more slowly than it did five years ago.

    It seems a place ripe for wide use of ride-hailing apps that, you might think, would reduce some of the jams. However, those apps appear to be making things worse as traffic has slowed in line with the growing popularity of apps such as Uber and Lyft, a study by transport expert Bruce Schaller suggests.

    Over the four years of the study, the number of cars in Manhattan seeking ride-hailing fares increased by 81%. There are now about 68, 000 ride-sharing drivers across New York. That's about five times the number of the yellow cabs licensed to operate there, he found. There are so many drivers, his work suggests, who spend about 45% of their spare time just touring for fares. That is a lot of unused cars blocking a lot of busy streets.

    Simple physics explains why ride-sharing vehicles are causing, not curing jams, said Jarrett Walker, a public transport policy expert who has advised hundreds of cities about moving people.

    "Lots of people are deciding that, 'Oh, public transport is just too much trouble this morning,' or whenever, which causes a shift from it," he told the BBC. "That means moving people from larger vehicles into smaller ones, which means more vehicles to move the same people. Therefore, more traffic."

    Data gathered about ride-sharing drivers illustrates how they contribute to congestion (塞车), said Prof. Christo Wilson, a computer scientist at Northeastern University who has studied the services. "You can look at the traffic pattern for the Uber vehicles and it perfectly matches the peaks for the rush hour and the peak time of a day," he said. They are out there in force at the worst possible times.

    A traditional Chinese cough syrup (糖浆), called Nin Jiom Pei Pa Koa (念慈庵川贝枇杷膏), is flying off the shelves in New York stores this flu season, following a US news report.

    According to a report in The Wall Street Journal last week, Mr. Alex Schweder, a professor of design at Pratt Institute suffering a cough for about 10 days, felt better 15 minutes after he drank a bottle of Nin Jiom Pei Pa Koa. It had been recommended by his girlfriend, who first learnt about the cough syrup 30 years ago when she was living in Hong Kong.

    Mr. Schweder was shocked by the magical effects of the cough syrup, and recommended it to many people. This, together with other factors, soon made the Chinese medicine popular in New York City.

    A 300ml bottle is now sold at US$13.29 on Walmart's website. This is more than double the former price in some pharmacies (药店) in Manhattan's Chinatown, selling at about US$6 per bottle. "The number of Nin Jiom Pei Pa Koa we sold over the past few days was much more than usual," said Winnie, a sales staff member of Buy-rite pharmacy in Chinatown. "More and more Westerners are accepting this medicine because it is effective," she said.

    According to the Kingworld Medicines Group's official website, Nin Jiom Pei Pa Koa is made of "valuable Chinese herbs and honey, and has surprising effects in treating coughs." However, experts warn that taking the cough syrup can carry health risks, including when it is used with other medicines, used too much or taken instead of prescription medication (处方药).

    Dr. Keith Brenner, a specialist in pulmonary medicine at Columbia University Medical Centre New York Presbyterian Hospital, said, "I think people who use these things may not even tell the doctor about them, and it's a problem."
