Mr. Hopkins said, "We have a verywide choice of items for sale. Whenever I serve a new customer, I take hispicture. "  Mr. Hopkins pointed toan ancient camera on a table.

    I began to appreciate the lovely itemson sale. I spent a very pleasant hour being shown the commodi-ties inthe shop. Finally,  I bought an antiquejewelry box, a pair of riding boots and a sewing machine.

    I was very excited that I had found sucha good little shop. "I will tell all my friends about your love-ly place." I told the shopkeeper. "Please don't do that, sir. " said Mr.Hopkins. "This is a special place for special people. You must keep thisshop a secret. " Then he took my photograph and handed me the picturestraight away.

    " That was quick! " Iexclaimed. In the picture I looked proud and excited holding the presents I hadbought there.

    On Christmas Day, my friends andrelatives were delighted with the presents I had bought for them.

    For weeks, my brother begged me to takehim to the wonderful little shop. I finally agreed.

We walked along Oxford Street, past thedepartment store and found—nothing. In its place was an empty space beingused as a car park. I checked the area again. There was the music shop, andthere was the department store. In between should have been Hopkins and Son,but it wasn't there.

    Just then, an old policeman came."Are you looking for something, sir?" he asked. "I am lookingfor a little shop called Hopkins and Son. "

    "Oh yes, there was a shop here'once called Hopkins and Son. But it was knocked down over 30 years ago. "

    I looked again at the place, then Ireached into my pocket and took out the photograph that Mr. Hop-kins had takenof me holding my presents in the little shop.

    " How strange!"  I screamed.

    Two recent studies have found that punishment is not the best way to influence behavior.

    One showed that adults are much more cooperative if they work in a system based on rewards. Researchers at Harvard University in the United States and the Stockholm School of Economics in Sweden did the study.

    They had about two hundred college students play a version of the game known as the Prisoner's Dilemma. The game is based on the tension between the interests of an individual and a group. The students played in groups of four. Each player could win points for the group, so they would all gain equally. But each player could also reward or punish each of the other three players. Harvard researcher David Rand says the most successful behavior proved to be cooperation. The groups that rewarded the most earned about twice as much in the game as the groups that rewarded the least. And the more a group punished itself, the lower its earnings. The study appeared last month in the journal Science.

    The other study involved children. It was presented last month in California at a conference on violence and abuse（虐待）. Researchers used intelligence tests given to two groups. More than eight hundred children were aged two to four the first time they were tested. More than seven hundred children were aged five to nine. The two groups were retested four years later, and the study compared the results with the first test. Both groups contained children whose parents used physical punishment and children whose parents did not.

    The study says the IQs of the younger children who were not spanked were five points higher than those who were. In the older group, the difference was almost three points. The more they are spanked, the slower their mental development.

    How to keep a good figure may be important to you. In fact, your house may have an effect on your figure. Experts say the way you design your home could play a role in whether you pack on the pounds or keep them off. You can make your environment work for you instead of against you. Here are some ways to turn your home into part of your diet plan.

    Open the curtains and turn up the lights. Dark environments are more likely to encourage overeating, for people are often less self-conscious when they're in poorly lit places—and so more likely to eat lots of food. If your home doesn't have enough window light, get more lamps and flood the place with brightness.

    Mind the colors. Research suggests warm colors fuel our appetites. In one study, people who ate meals in a blue room consumed 33 percent less than those in a yellow or red room. Warm colors like yellow make food appear more appetizing, while cold colors make us feel less hungry. So when it's time to repaint, go blue.

    Don't forget the clock—or the radio. People who eat slowly tend to consume about 70 fewer calories per meal than those who rush through their meals. Begin keeping track of the time, and try to make dinner last at least 30 minutes. And while you're at it, actually sit down to eat. If you need some help slowing down, turn on relaxing music. It makes you less likely to rush through a meal.

    Downsize the dishes. Big serving bowls and plates can easily make us fat. We eat about 22 percent more when using a 12-inch plate instead of a 10-inch plate. When we choose a large spoon over a smaller one, total intake jumps by 14 percent. And we'll pour about 30 percent more liquid into a short, wide glass than a tall, skinny glass.

    It is one of the oldest magic tricks in the book—a magician locks a woman in a box, with her head and feet sticking out from either end, and saws (锯) it in half. But when she finally jumps out of the box, the woman is unharmed.

    This trick was introduced nearly a century ago. It has been around for some time, but it never goes wrong. Why is it so successful? The answer is simple: the human mind is easily fooled.

    Our brain processes the world around us based on information that sensory organs, including the eyes, pick up. For instance, when we see a cow or a horse standing behind a tree, we automatically “fill in” the part of the animal's body that is hidden from our sight. “So the brain is taking this kind of very sparse (匮乏的) information about the world and it's generating this rich world by filling in information,” Stephen Macknik, a scientist at the Barrow Neurological Institute in Arizona, US, told Science magazine.

    But since our brains are filling in the gaps, sometimes they get it wrong. They tend to be driven by our previous experiences and we expect things to go as they have in the past even if sometimes they do not.

    This tendency explains magicians' success in fooling people with well-known coin tricks. For example, when you see a magician throw a coin up and down in one hand and then fake a coin thrown to the other hand, you would naturally believe that the coin is in the other hand.

Apart from the information gaps, magicians also use the “blind spots” theory when doing their shows.

    The most well-known experiment demonstrating this theory is called the “invisible gorilla (大猩猩)”, in which volunteers watch a video of two basketball teams. They are asked to count how many times the teams wearing white shirts pass the ball. In the meantime, a person dressed as a gorilla walks onto the court. But shockingly, half of the viewers don't notice the gorilla, even when they appear to be looking directly at it.

    Magicians employ this tactic (招数), what they call “misdirection”, in almost every one of their acts. They direct our attention somewhere else using comedy and music, which can make us miss stuff during the performance.

    How to fight California's wildfires? It's an “all of the above” respond.

There might, indeed, be a need to make it easier to thin dying or dead trees out of thickly forested areas, reducing the fuel for wildfires. But the problem is actually more complicated. Even if dead trees are removed, the dry bushes act like kindling (引火物) when wildfires spread.

    Even more to the point, thick forests were not a factor in these recent California's fires. “They're using these fires to talk about forest management that has nothing to do with the landscape in which the fires are occurring,” says Chur Miller. W. M. Keck Professor of Environmental Analysis and History at Pomona College in Claremont, California.

    Climate change is making wildfires worse. The resulting unpredictable weather patterns have created shorter, wetter winters in California, producing a sudden, heavy growth of brushes, grasses and trees. After winter, the state's ongoing drought and record- high summer temperatures draw water out of the plants, making them near-perfect kindling. With the hot and dry Santa Ana winds of fall, fires explode out of control.

    Yet these tragedies can't be blame only on global warming. Wildfires are actually a vital of the state's ecosystem. Lodgepole pines (松树), for example, grow well in fire-prone areas where millions of structures have been built in rural areas of California since the 1940s.When they bum, the cost in lives and treasures skyrockets.

Answering these disasters with a one-dimensional solution helps no one, although it might score short-term political points. The proper response includes placing limits on residential expansion into wildlands; better management and removal of dry brushes and continuously addressing the growing concern of climate changes.

    In other words, the solution isn't either/or. It's all of the above.
