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.

    I have an interest in photography and follow many photography Instagram accounts. Just like me, a friend of mine has a similar interest. The only difference is that he is a traveller and has taken hundreds of beautiful photos. He is really talented.

    Having returned from one trip, he shared some of his latest photos. Blown away by the images, I asked him why he hadn't started his own Instagram account of shots.

    “It's hard to start when there are already so many other websites devoted to travel photography with thousands of followers”, he explained. “What if I don't get any followers or what if people don't like my shots?”

    “Yet how will you ever know if you don't try?” I asked.

    He just shrugged and quickly changed the subject. I knew this feeling well. The feeling of self-doubt.

    That was when I was ten years old. I participated in a guitar competition. My grandfather helped me write a short speech to address the crowd and judges. But as the competition began, doubt consumed me and questions flooded my head. I thought to myself, “If I do say the speech, will the other girls laugh at me? Will the judges think I'm being silly for doing my own talk?”

    Then with a shake in my voice I said, “My name is Heidi Ceci. I live in St. Catharines and I play the guitar.” Nothing more... and nothing less.

    But the next girl walked up to the microphone and actually said a speech. I just stared at her in complete disbelief. No one seemed to be judging her for doing something different. In fact, they applauded louder for her than any other girl.

    From then on, I never let fear and doubt rule my decisions. Whatever happens, I always take chances and have a try.

    The American Heart Association (AHA) says that too many people are spending far too much time on chairs and couches. "Based on existing evidence, we found that U.S. adults are sedentary for about six to eight hours a day, "said Deborah Rohm Young, chair of AHA panel that wrote the new advisory.

    According to the AHA, growing evidence shows that, on its own, exercise isn't enough to cancel out the unhealthy effects of sitting for a long time. "Regardless of how much physical activity someone gets, long sedentary time could negatively influence the health of your heart and blood vessels," Young explained.

    The exact mechanisms behind the effect aren't yet clear. “There are many important factors we don't understand about sedentary time yet," Young said. She stressed that, "the types of studies available identify trends but don't prove cause and effect.”

    "We don't have information about how much sedentary behavior is bad for health — the best advice at this time is to 'sit less and move more,” she added.

    How much more? According to the AHA, people should try to get at least 30 minutes of moderate to vigorous (剧烈的）exercise a day to reach the recommended 150 minutes of moderate exercise or 75 minutes of vigorous exercise a week, That's healthier than trying to cram their weekly exercise into one or two days, according to the statement.

    "The real risk simply comes down to the amount we sit, without there being a true medicine or method to control the harmful effects," said Steinbaum, a preventive specialist in heart disease.

    Still, society has evolved to encourage sitting, she added.

    "Our lives have become focused around activities requiring us to be still—whether it be transportation, our computers, or the television or computer in our leisure time,” Steinbaum said. "Sociologically, instead of being active to be productive or to have enjoyment, our productivity and fun often requires minimal physical activities."

    In 2001, British Prime Minister, Tony Blair said," We celebrate the diversity(多样性) in our country, get strength from the cultures and the races that go to make up Britain today."

    People from all cultures and races can be found in every corner of Britain and each person in his or her own way has contributed to making Britain the place it is today.

    If you walk down a street in Britain, especially in the bigger cities, you will usually see people with different hair, skin and eye colors. They may have white, brown or black skin and blonde, brown, black or red hair, with blue, black, brown or green eyes. Many of the people you will see will be British people but they all look different because the people of Britain are a mixed race.

    Britain is and has always been a mixed race society. Early in the British history they were invaded by Romans, Saxons, Vikings and Normans armies and later Africans were brought to Britain by force in the seventeenth and eighteenth centuries as slaves or servants. Over the years, thousands of people have been forced by persecution(迫害) or hunger to leave France, Ireland, Russia, and other countries, and have settled in Britain.

    About 8% of the population of Britain today are people from other cultures and races. That is 4.6 million people. According to a BBC report in September 2005, immigration (移民) made up more than half of Britain's population growth from 1991 to 2001.The Guardian newspaper reported in 2007 that the number of immigrants to the UK was 145,000 a year.

    People moving to Britain have brought their own cultures with them and try to keep them alive. An excellent example of this is the Notting Hill Carnival which celebrates the Caribbean culture and is now a very big part of British life today.
