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.

    Soft winds blew throughout the Windy City today. We welcomed the winds, as it was another hot day in Chicago. The wind blew, bringing us some coolness and making the weather not that hot. But it was a beautiful summer day with a blue sky.

    Chicago is a great city for eating, and we have enjoyed tasting the different foods. Last night, we tried one of the city's most famous foods: deep-dish pizza. Chicago claims credit for the rich and cheesy thick-crust pizza, covered with a sweet tomato sauce. We topped it with olives and green peppers.

    We were touring the city, mainly looking for delicious local foods. Today, we enjoyed a Polish specialty at lunch: Pierogis, an Eastern European dumpling-like dish, filled with foods like potatoes, cheese, mushrooms, cabbage and meat. Polish immigrants started settling in Chicago in the 1850s, and the city has one of the largest Polish communities in the U.S.

    We took a break from exploring the city to talk with some of you! Ashley and Caty logged onto the Internet for an on-the-road version of TALK2US. We spoke to an English teacher in Tokyo, Japan, and a graduate student in India.

    Meanwhile, Adam searched for some locations around the city to shoot some video. He chose a spectacular spot: Navy Pier, Chicago's most-visited attraction. The winds from Lake Michigan keep visitors cool, and the view of the Chicago skyline never fails to impress. In fact, the view made all of us head over heels!

    Our time in Chicago has come to an end. Tomorrow, the true journey begins, as we pass through Illinois and into Missouri via Route 66. Springfield, the home of Abe Lincoln, and St. Louis, the "gateway to the West," wait for us.

    Humans were designed to stand upright(直立). And yet in this modern world, too many of us spend our days with our heads lowered for a simple reason: we're staring at the tiny screen of a smart phone.

    People spend an average of 2 to 4 hours each day with their neck bent while shooting off emails or texts. That's 700 to 1,400 hours a year. The success of social media has led to a rapid development of bad smart phone posture.

    The average adult head weighs 10 to 12 pounds when it's in the upright position. However, because of the gravity, bending your head at a mere 15 degree puts 27 pounds of pressure on your spine(脊椎)；a 30 degree neck bend could equal(等于) 40 pounds of pressure; a 45 degree bend adds the force of 49 pounds, according to the research from Dr. Kenneth Hansraj from New York. These stresses may lead to many problems.

    It's no secret that correct posture is better for your back. According to the researchers, good posture is described as ears aligned(成一条直线) with the shoulders. In proper alignment, spinal stress disappeared. It is the best position for the spine. Standing tall doesn't just make you look better; it improves your health, too. Other studies have found good posture has even been connected to ways of behaving. People who have poorer posture often have poorer physical and emotional health.

    The researchers describe bad posture（姿势）as “the head in a forward position and the shoulders dropping forward in a rounded position”. Bad posture has been connected to many medical problems, including headaches and other problems, depression and heart disease. This is why Hansraj said it's important to be mindful of your smart phone posture. While it is nearly impossible to avoid the technologies that cause these problems, people should make an effort to look at their phones with a correct posture.

    When I started teaching at school, I was sure I would change the world and touch children who needed love.

    Although my students seemed to respond pretty well to my teaching , there was a small group of girls who became more and more hostile towards me.

    One day a fight happened in my classroom. Trying to end it, I stepped in to face one of these hostile young women, who started hitting me in the face. Two boys jumped up to control the girl, but the damage was done.

    While the girl was suspended for a few days, I was determined that she would not return to my classroom. But I also prayed. I wanted to see all the students right there in my daily work at school.

    On the top of my daily lesson-plan book, I wrote this statement, “To see all the children in my classroom is always beautiful.” With this view I could expect to heal any anger towards the girl in my heart.

    After her suspension, she returned to my classroom. The student's young mother was trying to raise six children while her husband was away in the war. The mother and I agreed to work together to help her oldest daughter.

    There were no more incidents of anger the rest of the year. In fact, in the seven years I remained at that school, I taught all six of this family's children. When the youngest was in my class, the mother told me, “Our family love you. Every year one of my kids says, ‘I hope I'm in her class!'”

    The standard of seeing each of my students as a perfect one was the best teaching tool I had, and led to success.

    A farmer grew some vegetables in his garden. One day his wife was ill and he had no money. He had to sell some cabbages and carrots in the market. The next morning he took two baskets of vegetables to town, but it was raining hard that afternoon and there were few people in the street. When his vegetables were sold out, it was dark. He bought some medicine and hurried to his village.

    On his way home he saw a person lying on the ground. He placed his baskets on the ground and was going to help the person to get up. At that time he found it was a dead man and there was much blood on his body. He was so afraid that he ran away quickly, without taking his baskets.

    The next afternoon the farmer was sent to the police station. Having shown the baskets, an officer asked, “Are these yours?" “Yes, sir." The farmer answered timidly（胆怯地）. “Have you killed the man?” “No, no, sir.” The farmer said in a hurry. “When did you see the dead man?” “About seven last evening." “Did you see who killed the man?” “No, sir." The officer brought out a knife and asked, “Have you seen it yet?” “No, sir." The officer became angry and told the policemen to beat him up and sent him into prison(监狱)。

    That evening the officer went on trying. Pointing to the knife, he asked again, “Have you seen it yet?” "yes, sir.” The officer was happy and asked, “When and where?” “I saw it here this afternoon, sir.”

    A woman in Pulaski, Virginia, says she was stopped by a squirrel, who pulled on her leg repeatedly and led her to help its injured baby.

    Tia Powell was walking in Kiwanis Park when she was "approached by a squirrel", the Pulaski Police Department wrote on Facebook. The squirrel stood in her way on the path. After realizing that the squirrel did not mean any harm and wasn't going to leave her side, Powell turned around and the squirrel led her down the path to a baby squirrel with an injured leg.

    At one point, Powell wasn't sure she could help and she began walking and the squirrel followed her again and actually pulled her trouser leg! So, she fed the squirrels a sandwich she had with her and watched them try to Jump up into a tree. When she realized the baby squirrel was still struggling to get up the tree, she decided to call in backup. Powell called the Pulaski Police Department.

    Powell didn't know how the baby squirrel got injured, but she thought a nearby street cat was the culprit (肇事者). So, the group of rescuers decided to move the squirrels to safer area. "We were able to get the baby and mother to a different area with more trees and it was able to climb all the way up and they looked very happy," Powell said.

    She went back a few days later to show her kids where it all went down. In the trees, Powell spotted two squirrels staring at her, and couldn't help but wonder if they were the same squirrels she rescued.
