In 2004 ,when my daughter Becky was ten , she and my husband ,Joe, were united in their desire for a dog . As for me , I shared none of their canine lust.

But why , they pleaded. “Because I don't have time to take care of a dog.” But we'll do it. ” Really? You're going to walk the dog? Feed the dog? Bathe the dog?” Yes, yes , and yes .”I don't believe you .” We will . We promise.

They didn't . From day two (everyone wanted to walk the cute puppy that first day ) , neither thought to walk the dog . While I was slow to accept that I would be the one to keep track of her shots , to schedule her vet appointments , to feed and clean her , Misty knew this on day one . As she looked up at the three new humans in her life (small, medium, and large) , she calculated ,”The medium one is the sucker in the pack .”

Quickly, she and I developed something very similar to a Vulcan mind meld (心灵融合) . She'd look at me with those sad brown eyes of hers , beam her need , and then wait , trusting I would understand — which , strangely , I almost always did . In no time , she became my feet as I read , and splaying across my stomach as I watched television .

Even so , part of me continued to resent walking duty .Joe and Becky had promised. Not fair , I'd balk (不心甘情愿地做) silently as she and I walked . “Not fair , ” I' d loudly remind anyone within earshot upon our return home .

       Then one day — January 1, 2007 , to be exact — my husband ‘ s doctor uttered an unthinkable word : leukemia ( 白血病) .With that , I spent eight to ten hours a day with Joe in the hospital , doing anything and everything I could to ease his discomfort. During those six months of hospitalizations, Becky, 12 at the time, adjusted to other adults being in the house when she returned from school. My work colleagues adjusted to my taking off at a moment's notice for medical emergencies. Every part of my life changed; no part of my old routine remained.

      Save one: Misty still needed walking. At the beginning, when friends offered to take her

through her paces, I declined because I knew they had their own households to deal with.

      As the months went by，I began to realize that I actually wanted to walk Misty. The walk in the morning before I headed to the hospital was a quiet, peaceful time to gather my thoughts or to just be before the day's medical drama unfolded. The evening walk was a time to shake off the day's upsets and let the worry tracks in my head go to white noise.

      When serious illness visits your household, it's , not just your daily routine and your assumptions about the future that are no longer familiar. Pretty much everyone you acts differently.

Not Misty. Take her for a walk, and she had no interest in Joe's blood counts or 'one marrow test results. On the street or in the park, she had only one thing on her mind: squirrels! She Was so joyous that even on the worst days, she could make me smile. On a daily basis she reminded me that life goes on.

      After Joe died in 2009，Misty slept on his pillow.

I'm grateful一to a point. The truth is, after years of balking, I've come to enjoy m' walks with Misty. As I watch her chase after a squirrel, throwing her whole being into the here-and-now of an exercise that has never once ended in victory, she reminds me, too, that no matter how harsh the present or unpredictable the future , there's almost always some measure of joy to be extracted from the moment.

    Argentina in the late nineteenth century was an exciting place. Around 1870, it was experiencing an economic(经济的)boom, and the capital, Buenos Aires, attracted many people. Farmers, as well as a flood of foreigners from Spain and Italy, came to Buenos Aires seeking jobs. These jobs didn′t pay well, and the people felt lonely and disappointed with their new life in the city. As the unhappy newcomers mixed together in the poor parts of the city, the dance known an the tango(探戈舞)came into being.

    At the beginning the tango was a dance of the lower classes. It was danced in the bars and streets. At that time there many fewer women than men, so if a man didn′t want to be left out, his only choice was to dance with another man so that he could attract the attention of the few available women. Gradually, the dance spread into the upper classes of Argentinean society and became more respectable.

    In Europe at this time, strong interest in dance from around the world was beginning.

    The interest in international dance was especially evident in Paris. Every kind of dance from ballet(芭蕾舞)to belly dancing could be found on the stages of the Paris theaters of the Paris theaters. After tango dances from Argentina arrive in Europe, they began to draw the interest of the public an they performed their exiting dance in cafes, Though not everyone approved of the new dance, saying it was a little too shocking, the dance did find enough supporters to make it popular.

    The popularity（流行）Of the tango continued to grow in many other parts of the world. Soldiers who returned to the United States from World War I brought the tango to North America, It reached Japan in 1926, and in 2003 the Argentinean embassy in Seoul hired a local tango dancer to act an a kind of dance ambassador, and promote tango dancing throughout South Korea.

    Are some people born clever, and others born stupid? Or is intelligence developed by our environment and our experience? Strangely enough, the answer to these questions is yes. To some degree our intelligence is given to us at birth, and no amount of education can make a genius out of a child born with low intelligence. On the other hand, a child who lives in a boring environment will develop his intelligence less than one who lives in rich and varied surroundings. Thus the limits of person's intelligence are fixed at birth, whether or not he reaches those limits will depend on his environment. This view, now held by most experts, can be supported in a number of ways.

    It is easy to show that intelligence is to some degree something we are born with. The closer the blood relationship between two people, the closer they are likely to be intelligent. Thus if we take two unrelated people at random from population, it is likely that their degree of intelligence will be completely different. If, on the other hand, we take two identical twins, they will very likely be as intelligent as each other. Relations like brothers and sisters, parents and children, usually have similar intelligence, and this clearly suggests that intelligence depends on birth. Imagine now that we take two identical twins and put them in different environments. We might send one, for example, to a university and the other to a factory where the work is boring. We would soon find differences in intelligence developing, and this indicates that environment as well as birth plays a part. This conclusion is also suggested by the fact that people who live in close contact with each other, but who are not related at all are likely to have similar degree of intelligence.

    Mirroring China's Past: Emperors and Their Bronzes

    Chinese bronzes (青铜) of the second and first millennia BC are some of the most distinctive achievements in the history of art. These vessels (容器) were made to carry sacrificial offerings, to use in burial or to honor noble families in public ceremonies. When they were found by emperors centuries later, these spiritually significant objects were seen as signs of heavenly messages about a ruler or a dynasty and became prized items in royal collections. This exhibition —the first to explore these ancient objects throughout Chinese history — presents a rare opportunity to experience a large number of these works together in the United States.

    Unlike Greek and Roman bronze sculptures of human and animal forms, most objects from Bronze Age China (about 2000 - 221 BC) were vessels for ceremonial use. Beginning with the Song dynasty (960 - 1279), emperors unearthed these symbolic works and began collecting them, considering them to be evidence of their own authority as rulers. In addition to impressive collections, the royal fascination with bronzes led to the creation of numerous reproductions and the comprehensive cataloguing of palace holdings. These catalogues are works of art themselves, featuring beautiful drawings and detailed descriptions of each object.

    From the 12th century onward, scholars and artists also engaged in collecting and understanding ancient bronzes. Unlike emperors, scholars regarded bronzes as material evidence of their efforts to recover and reconstruct the past, and they occasionally exchanged them as tokens (象征) of friendship. Today ancient bronzes still occupy a primary position in Chinese culture — as historical objects and as signifiers of an important cultural heritage that inspires new generations, as seen in the works of contemporary artists on view in this presentation.

    Mirroring China's Past brings together approximately 180 works from the An Institute of Chicago's strong holdings and from the Palace Museum in Beijing, the Shanghai Museum, and important museums and private collections in the United States. By providing viewers with a new understanding of ancient bronzes and their significance through time, the exhibition demonstrates China's fascinating history and its developing present.

    This year's flu season is pretty scary. To try to minimize the effects, public officials are still urging anyone who hasn't yet gotten their flu shot to get one as soon as possible. However, even if every single person got a shot in the arm, the vaccine(疫苗)—with its excellent 36 percent effectiveness—would not prevent everyone from getting infected with the annoying virus. Knowledge is power, so here's what goes on in your body when you come down with the flu.

    The influenza virus primarily attacks your nose, throat, and the tubes that lead to your lungs. But the flu is so much more than that. Your muscles ache, your head hurts, and your appetite goes down, among other things. To our surprise, almost all of these symptoms have less to do with the virus itself than with your immune(免疫的)response to them. Unfortunately, the very defense you have in place to get rid of the flu is the reason you feel so painful when you recover.

    The virus usually enters through your mouth, typically by way of your hands But it takes a few days for symptoms to set in. While this process might cause some harm to your nose and throat, it's nothing major, and nothing like the symptoms that typically accompany a bad or even mild case of the flu.

    The real fun starts when your immune system begins to fight. Your immune system comes in two parts: the innate system and the adaptive. The innate immune system is essentially an all-purpose tool. As soon as your body senses the presence of any injury or invader (入侵者), the innate immune system launches into action by producing tiny proteins called cytokines and chemokines. The cytokines reproduce almost immediately and start to attack the virus. This increase in immune cells creates an serious inflammation(炎症) throughout the body. But the worst is still to come. Meanwhile, the chemokines work with the adaptive immune system to help create T cells. These cells are a special type of white blood cell that works in a much more specific way: They find the influenza virus, identify what's special about it, and create something unique on their surface that finds and destroys similar invaders.

Incredible experiences in Bucharest

    Admire one of the world's largest buildings

    The world's biggest parliamentary building, Palace of Parliament, happens to be in Bucharest. Hour-long guided tours manage to take in just a fraction of the building's three-million-plus square feet (there are more than a thousand rooms) and focus on the tons of marble, hardwood, and gold used in the building's construction in the 1980s, a time when Romania was trying to feed its own people. Ceausescu and his wife, Elena, both played a direct role in the construction. It was originally intended to house the presidential offices and the Central Committee of the Romanian Communist Party but was never finished.

    See remains of old “Paris”

    “Paris of the East” was Bucharest's nickname in the decades before World War II. Decades of communist misrule and a tragic earthquake in 1977 brought much of the old city down but there are places here and there where that former elegance can still be glimpsed. The Cismigiu Gardens in the center of the city is a pearl of park built around a romantic lake and featuring old-growth trees and gracious, wrought-iron signposts and benches.

    Learn about Romania's roots

    Walking though Bucharest's busy streets, it's easy to forget that outside the capital and a U large cities, Romania is a largely agricultural country, with a long and rich peasant tradition. The amazing Museum of the Romanian Peasant shows off the elaborate woodworking, pottery-making, egg-painting, and weaving skills of the peasantry in a way that's both educational and amusing. Small tongue-in-cheek signs at the entrance to each room poke fun at modern life, bring a chuckle, and draw you in. Downstairs there's a side exhibition on the Communists' efforts to nationalize the peasantry in the 1970s and 1980s.

    Appreciate 21st-century art

    Romania has exploded onto the contemporary art scene in recent years. The excitement was generated initially by a group of young painters and visual artists from the northern city of Cluj-Napoca, but at least some of the action has shifted to the capital as new galleries and design centers open up. It's hard to pinpoint precisely what constitutes Romanian contemporary art, though critics point to shared elements of wit and dark humor, a somber mood, and bits of surrealism in defining a common style.
