While household robots today do the normal housework, social robots will be much more like companions than mere tools. For example, these robots will be able to distinguish when someone is happy or sad. This allows them to respond more appropriately to the user.

The Jibo robot, arranged to ship later this year, is designed to be a personalized assistant. You can talk to the robot, ask it questions, and make requests for it to perform different tasks. The robot doesn't just deliver general answers to questions; it responds based on what it learns about each individual in the household. It can do things such as reminding an elderly family member to take medicine or taking family photos.

         Social robots are not just finding their way into the home. They have potential applications in everything from education to health care and are already finding their way into some of these spaces.

Fellow Robots is one company bringing social robots to the market. The company's “Oshbot” robot is built to assist customers in a store, which can help the customers find items and help guide them to the product's location in the store. It can also speak different languages and make recommendations for different items based on what the customer is shopping for.

          The more interaction the robot has with humans, the more it learns. But Oshbot, like other social robots, is not intended to replace workers, but to work alongside other employees. “We have technologies to train social robots to do things not for us, but with us,” said Breazeal.

    Christmas was coming, I was considering what present I should prepare for my father.My dad never wants anything, for he is a hard person to buy for . I pulled out my phone to read text message from my mom saying that we were leaving for Christmas shopping for him when I came across a message on my phone that I had locked. The message was from my father.My eyes fell on a photo of a flower taken in Wyoming，and underneath a poem by William Blake. The flower，a lone dandelion standing against the bright blue sky，inspired me. My dad had been reciting those words to me since I was a kid. That may even be the reason why I love writing. I decided that those words would be my gift to my father.

    I called back. I told my mom to go without me and that I already created my gift. I sent the photo of the cream ­colored flower to my computer and typed the poem on top of it. As I was arranging the details another poem came to mind .The poem was written by Edgar Allan Poe；my dad recited it as much as he did the other. I typed that out as well and searched online for a background to the words of it. The poem was focused around dreaming，and after searching I found the perfect picture. The image was painted with blues and greens and purples，twisting together to create the theme and wonder of a dream. As I watched both poems passing through the printer，the white paper coloring with words that shaped my childhood. I felt that this was a gift that my father would truly appreciate.

    Christmas soon arrived. The minute I saw the look on my dad's face as he unwrapped those swirling black letters carefully placed in a cheap frame，I knew I had given the perfect gift.

    Peruvian novelist, Mario Vargas Llosa, who received Nobel Prize for Literature in 2010, is one of the central writers in Latin America, but he began his literary career in Europe.

    Mario Vargas Llosa was born in Arequipa, but from age one he lived in Cochabamba, Bolivia, where he was brought up by his mother and grandparents after his parents separated. However, Vargas Llosa once said that "I feel very much an Arequipan"．He also spent some time in Piura, northern Peru (1945～1946)．

    Vargas Llosa attended Leoncio Prado Military Academy (1950～1952), and Colegio Nacional San Miguel de Piura (1952), Peru． In 1955 he married Julia Urquidi; they divorced in 1964.From 1955 to 1957 Vargas Llosa studied literature and law at the University of San Marcos, Peru. He then attended post-graduate school at the University of Madrid, Spain, where he received his Ph.D.in 1959.

    In the 1950s, while still a student, Vargas Llosa worked as a journalist for La Industria. His first collection of short stories, LOSJEFES, appeared in 1959."I liked Faulkner but I imitated Hemingway, "he said later. Vargas Llosa moved to Paris because he felt that in Peru he could not earn his living as a serious writer. Although the boom of Latin American fiction in the 1960s opened doors to some authors for commercial success, the great majority of Peruvian writers suffered from the problems of the country's publishing industry. In France Vargas Llosa worked as Spanish teacher, journalist and broadcaster. From the late 1960s Vargas Llosa worked as a visiting professor at many American and European universities. In 1970 Vargas Llosa moved to Barcelona and five years later he settled back in Peru. Most of his novels are set in Peru.

    In addition to the Nobel Prize, Vargas Llosa has received many other honors. Among the most notable are Leopoldo Alas Prize (1959), Peruvian National Prize (1967) and Miguel de Cervantes Prize (1994).

    As early as 2005, there were a number of new stories about dog cloning(克隆) and cat cloning. Animal cloning had been old news for nearly a decade by then, with the revolutionary (革命的) cloning of Dolly the sheep in Scotland.

    However, Snuppy was the first pet, a dog, to be cloned. Since the cloning of Snuppy, there has been some very successful cloning of pets and other animals. Lou Hawthorne started BioArts while cloning his beloved mixed-breed dog Missy. Hawthorne was very pleased with the results of the cloning, producing three successful clones that were very alike to the original in character and behavior. In January, 2009, a Florida couple, Ed and Nina Otto, announced that they had paid to have their dog cloned by BioArts.

    All new technology is overpriced. For example, personal computers were not very affordable at first. Only after the producing process was improved was it possible for every family to have a computer. How much room there will be for organizations to reduce the price point on pet cloning without broad demand is of course questionable.

    There are many great dogs and cats that can be found at the local dog pound (野狗收容所) or are given away for "free to good homes" in classified ads (分类广告). However, there is no limit to the value people place on a beloved pet. The Ottos are a good example of that. If people can buy a dog or cat with predictable behavior and characteristics, there is value in that. There is a predictable market here, though it may always be limited in size.

    While pet cloning has not taken off as some hoped, it's clear that it will become a bigger market in the future and it will be increasingly possible for people to try this out. With the inevitable (不可避免的) success that cloned pet owners will have, the practice will become more widely accepted and it seems inevitable that there is a future for cloned dogs and cats.
