Humans have been keeping animals as pets for tens of thousands of years, but Dr Jean-Loup Rault, an animal scientist at the University of Melbourne in Australia, believes new companions are coming: robot pets.

    “Technology is moving very fast,” Rault told ABC News, “The Tamagotchi in the early 1990s was really the first robotic pet, and now Sony and other big companies have improved them a lot.”

    This may not sit well with pet lovers. After all, who would choose a plastic toy over a lovely puppy? But Rault argues that the robotic kind has a lot going for it: “You don't have to feed it, you don't have to walk it, it won't make a mess in your house, and you can go on a holiday without feeling guilty.” The technology also benefits those who are allergic to pets, short on space, or fearful of real animals.

    It's not clear whether robot pets can replace real ones. But studies do suggest that we can bond with these smart machines. People give their cars names and kids give their toy animals life stories. It's the same with robots. When Sony stopped its repair service for its robot dog Aibo in March 2014, owners in Japan held funerals.

    As an animal welfare researcher, Rault is concerned about how robotic pets could affect our attitudes towards live animals. “If we become used to a robotic companion that doesn't need food, water or exercises, perhaps it will change how humans care about other living beings,” he said.

    So are dogs and cats a thing of the past, as Rault predicts? For those who grew up with living and breathing pets, the mechanical kind might not do. But for our next generation who are in constant touch with smart technology, a future in which lovely pets needn't have a heartbeat might not be a far-fetched dream.

    Elizabeth Blackwell was the first woman doctor in the United States. Her success opened the way for other women who wanted to do more than nursing. She was born in England in 1821 and her family moved to America when she was eleven years old.

    The Blackwell girls received the same education as their brothers. This was most unusual in those days. Their father died young and they had very little money to live on. Elizabeth and her sisters taught at school. Then a woman dying of cancer urged Elizabeth to study medicine, saying that a woman doctor would have saved her from her worst sufferings. Nearly everyone said a girl should not go to medical school, but she managed to enter Geneva College in New York State. She graduated in 1849 at the head of her class and received the first medical degree ever given to a woman.

    Next, Dr. Blackwell went to Paris. Her only chance of training was in a hospital where women came to have their babies. Four months later, while she was working in the French hospital, her left eye became dangerously infected (感染). She lost the eye. She was very disappointed. But she was soon back at work again, this time in London, England. There she met many famous scientists.

    In 1859, Elizabeth Blackwell was officially recognized as a doctor in Great Britain — the first woman to be honored. She was the inspiration of Elizabeth Garrett, who began the women's medical movement in England. Florence Nightingale, founder of the practice of nursing by women, was another of her friends.

    Dr. Blackwell died in 1910 at the age of 89.

    Cosmetic surgery (整容手术) is not something to be entered into lightly. Unfortunately, in this modern world, we have become confused by very narrow standards of beauty. Images of stars who never seem to age are seen everywhere these days. We forget the fact that most of these images are the result of super photo manipulation (处理), driven by the extremely powerful beauty industry. We are all different — why should we all look the same? Isn't there more to life than having surgery in order to have the same boring face that everybody else wants to have?

—Dr Elisabeth McKenna, Psychologist

    Yes, it's not real! That's what I told my friends when they started asking me about my nose job. I'd always been sensitive to my nose, but it took me a long time before I decided to go for cosmetic surgery. I took advice from several doctors and after careful consideration I finally decided to have it done. I had been saving money from my part-time job and my parents helped me out with the rest. It was quite expensive but I don't regret a penny of it. In fact I wish I'd had it done a few years ago. I' m sure I wouldn't have been laughed at so much at school.

—Debbie Caron, Student

    It makes me really angry to think of the millions of people who spend much money on cosmetic surgery. Surgery should be carried out for medical purposes, not vanity (虚荣心). I would rather all the money spent on cosmetic surgery was used to treat people around the world who are in need but can't get proper medical treatment. Furthermore, there are thousands of under-qualified doctors out there who only care about getting as rich as possible as quickly as possible. They don't care about the psychological and physical damage they do. The whole industry makes me sick. We should do something to stop it.

    When you see someone you know, the easiest way to recognize them is by their face—but not everyone can do this. Many people have prosopagnosia, or face blindness, which is a neurological（神经病学的）condition where the part of the brain that recognizes faces fails to develop. It can stop people recognizing partners, family members, friends or even their own reflection. It was once thought to be caused by brain injury (acquired prosopagnosia) but now a genetic link has been proved (development prosopagnosia).

    Acquired prosopagnosia is a very rare but as many as one in 50 people may have developmental prosopagnosia. There's no specific treatment, but training programmes are being developed to help improve facial recognition.

    For many, the situation can be dangerous. I've heard stories of people being robbed by strangers claiming to be family members, or of children wandering off strange men.

    It was only is this century that researchers began to realize exactly how many people in this world were quietly living with the condition.

    Like a blind person who can recognize family members by their footsteps, prosopagnosics are forced to develop unusual ways of discovering who it is they're meeting or talking to. From the obvious markers like hair and voice, to the way one sits, stands or walks, they rely on dozens of means to get through ordinary life.

    Faces are an important part of identity. Not to be recognized feels terrible—it's as if you've been overlooked, like someone's saying you don't matter. But it's nothing to the pain of knowing that you're hurting people's feelings constantly, and yet being completely unaware that you're doing it in the moment. To be alienated（隔离的）from the world of faces is a strange position to be in, but I'm comforted by the thought that articles like this will do a little to help people forgive me and others like me.

    Years ago, the American writer Kurt Vonnegut often said there was one story that would always make a million dollars: "Cinderella"(《灰姑娘》).

    "Cinderella" made more like $70 million in ticket sales when it opened last weekend. But the movie got a mixed reaction. David Rooney of The Hollywood Reporter praised the movie and said, "Anyone will find something to enjoy in it." Steven Rea of The Philadelphia Inquirer called the movie "a winning re-do." Richard Corliss of Time magazine wrote that "Disney finally got Cinderella right." Other people were not as happy with the movie. Sara Stewart of the New York Post wrote, "This Cinderella is all dressed up with nowhere very interesting to go."

    Although different people think differently towards the movie, what is clear, however, is the movie's business success. It is not only popular in the theaters but also in sale. And Disney has widened its usual market for "Cinderella" products.

    There are products connected to the Disney movie targeted(面向) not only at little girls, but women, too. For example, the famous shoe designer Jimmy Choo worked with Disney to create "Cinderella's shoes." You can buy them for about $5,000. At that price, you would not want to lose one at the party, even if that is the way you get your prince(王子).

    The makeup(化装品) company MAC quickly sold all its products connected to "Cinderella." HSN is a popular website selling clothing and objects for the home. The marketer is now also selling "Cinderella" products.

    So, is there anything left for the children, those people we think of as the traditional audience for the age-old tale? Yes, you can find toys and other children's products at the American store JC Penney. Of course, you can also visit a Disney store.

    My sister and I were flying by ourselves from our home in Kansas to a summer camp in Minnesota. Our plane had a two-hour stop at the airport in Omaha, Nebraska. A flight attendant took us to a souvenir shop, where a toy airplane looked just like the plane my sister and I were flying on. I really wanted that airplane. I had $10 and the plane cost $8. I had no idea what I needed to buy at camp, but I bought the plane anyway. When we reached the camp, I discovered that there were no showers! Instead, we bathed in a lake every night. I needed to buy special soap because the regular soap I brought had chemicals that could harm the fish. The special soap cost $4 at the camp store. However, I had only $2 left.

    What upset me was that I couldn't get clean without the soap, which was soon found by my teacher, Sally. I had to tell her that I had spent most of my money on a toy airplane. She laughed and explained to me that a budget was necessary and it was a plan for spending money to help make sure you set aside enough for things you need, like soap, before you buy fun things, like toys.

    Sally gave me one of her extra(额外的) bottles of special soap. When I returned home, I decided to budget. I spent several weeks writing down everything I bought, just to get an idea of how I was already spending my money. Then I made my first weekly budget. My budget wasn't always the same each week. For some weeks, I would have more in my “Money In” account because I did some jobs around the house. Once summer vacation started, I didn't need to buy school lunches, so I had extra money to go to the neighborhood swimming pool or to give to the town animal shelter.

    Budgeting was hard, sometimes. Whatever week it was, I always made sure that “Money In” equaled “Save and Spend.” That's called making ends meet, and it's how you make sure that the money you have will always be enough to cover your plans to spend and save.
