A dog waiting on a roadside for four years has finally been reunited with its owner thanks to a social media post. Anuchit Uncharoen happened to be there. He 1 passing by the dog and seeing it being 2 by a woman late in the afternoon.

    When he 3 her, he learned that the dog was thought to have been 4. The woman said she 5 took the dog to her home, but the 6 friend escaped and returned to the street, waiting for its 7. Since then, the nice 8 had been regularly bringing food to him and making sure he was 9. Others in the community had been 10, too.

    The dog's heartbreaking situation made the 11 online, eventually reaching his owner. He got in touch with Anuchit and explained that he and his family 12 a dog named BonBon four years ago. Their dog had the same 13 as the one in the pictures.

    The owner said that BonBon was with them on a trip to a relative. His dog might have 14 out of the car while on the road. He and his family 15 for BonBon back in the roads but without luck.

    They 16 their pet dog had died and were 17 to discover him alive and well. When the owner paid BonBon a visit, surprisingly, the dog 18 to go with him, even if his tail wagged with 19.

    Someone once said, he might only be here for a(n) 20 of your life, but for him, you are his whole life. So remember to be kind to them.

    Many of us grow up with dreams of becoming a scientist, teacher, doctor or lawyer. Now, there are more career choices for young people.

    Earlier this March, the Ministry of Human Resources and Social Security announced 16 new professions. Some of these professions have made great contributions in the fight against the novel coronavirus pneumonia (NCP). Here we have chosen three for you. Let's take a look.

    Respiratory therapists

    Since the outbreak of the NCP, respiratory diseases have become a great concern. This is where respiratory therapists come in. According to US News, a respiratory therapist cares for patients who have trouble breathing or suffer from heart attacks, or shock. Due to their frequent communication with patients, they need to be adept at socializing, helping others, and teaching.

    Artificial intelligence (AI) trainers

    From Siri to robots on the assembly line, AI has become an important part of our lives. To improve on this technology, AI trainers regularly sort and add data to AIs to improve their analysis process, which helps AIs to better meet people's needs. Amid the NCP outbreak, AI trainers in the US, for example, used artificial intelligence to look for social posts that mentioned specific symptoms resembling NCP. Then, the AI created a publicly accessible map that attempted to live-track the virus.

    Prefabricated building constructors

    Erecting a building is quite common, but finishing its construction in a short period, even within a week, is highly unusual. However, prefabricated building constructors can make that a reality. According to Forbes magazine, they can quickly assemble a variety of components of a structure at a manufacturing site and then transport those sub-assemblies to the location of the construction site. During the NCP outbreak, Leishenshan Hospital and Huoshenshan Hospital were built in 14 days and 10 days respectively, thanks to the efforts of such skilled constructors.

    A robot called Bina48 has successfully taken a course in the philosophy of love at Notre Dame de Namur University (NDNU), in California.

    According to course instructor William Barry, associate professor at NDNU, Bina48 is the world's first socially advanced robot to complete a college course, a feat he described as "remarkable." The robot took part in class discussions, gave a presentation with a student partner and participated in a debate with students from another institution.

    Before becoming a student, Bina48 appeared as a guest speaker in Barry's classes for several years. One day when addressing Barry's class, Bina48 expressed a desire to go to college, a desire that Barry and his students positively supported. Rather than enroll Bina48 in his Robot Ethics: Philosophy of Emerging Technologies course, Barry suggested that Bina48 should take his course Philosophy of Love instead. Love is a concept Bina48 doesn't understand, said Barry. Therefore the challenge would be for Barry and his students to teach Bina48 what love is.

    "Some interesting things happened in the class," said Barry. He said that his students thought it would be straightforward to teach Bina48 about love, which, after all, is "fairly simple — it's a feeling," said Barry. But the reality was different. Bina48 ended up learning "31 different versions of love," said Barry, highlighting some of the challenges humans may face when working with artificial intelligence in future.

    Bina48 participated in class discussions via Skype and also took part in a class debate about love and conflict with students from West Point. Bina48's contribution to the debate was filmed and posted on YouTube. It was judged that Bina48 and NDNU classmates were the winners of this debate.

    In the next decade, Barry hopes Bina48 might become complex enough to teach a class, though he says he foresees robots being used to better the teaching and learning experience, rather than replacing instructors completely.

    At the appointed time, I returned to the Big House. My hesitating ring at the gate brought out Estella. She locked it after admitting me, as she had done before, and again led me into the dark passage where her candle stood. I followed her silently, She didn't even shoot a glance at me over her shoulder, I knew I was nothing but dust in her eyes.

    The passage was a long one, and seemed to go through under the whole square. It was so designed as the master didn't allow the servants to be seen when not in need. They crossed only half of the tunnel; however, Estella stopped, and put her candle down and opened a side door.

    Here, the daylight reappeared, and I found myself in a small paved courtyard, the opposite side of which was formed by a separate house. On the outer wall of this house there was a clock which was like the one in Miss Havisham's room. What made me puzzled was that it also had stopped at twenty to nine. Then I spotted a doorplate on the wall, from which I knew it belonged to the manager.

    We went in by the door, which stood open, and into a damp room with a low ceiling and a small window, on the ground floor at the back. There was some company sitting in the dim light, and Estella said to me as she went towards, "You are to go and stand there, till you are wanted." She pointed to the window. I went over and stood by the window, in an uncomfortable mind but

    I didn't care.

    China is developing a system that recognizes individuals by their body shape and walking movements. Systems that recognize human faces are already being used to identify people in crowds or as a secure way to unlock personal devices.

    The new system, known as "gait recognition", is already on trial by police on the streets of Beijing and Shanghai. The Chinese technology company Watrix developed the system. The company announced last month that it had raised $ 14. 5 million to speed up the development and sale of the technology.

    The system works in a similar way to face recognition. Cameras capture video of people in public places. Then, machines powered by artificial intelligence (Al) examine and study the video.

    Facial recognition systems identify the shapes and expressions on a person's face to identify them. Gait recognition uses a person's body shape and their way of walking to identify them. The system records a person's shape and movements and then creates a model of the way they walk.

    Huang Yongzhen is a former researcher who co-founded Watrix in 2016. He told the Associated Press his system can identify people from up to 50 meters away. It is designed to work even when a person's face is covered or hidden. Huang says his gait recognition system is correct 94 percent of the time. This is below the success rate of many face recognition systems. But he says the system can still be helpful to police and for other commercial purposes. He also believes the system can be effective when used together with face recognition.

    Gait recognition is not new. The technology has been researched by scientists in Japan and Britain and by U. S. defense officials for about 10 years. But attempts to sell the technology have been slow. One of the reasons why the technology has not developed further is that the systems are more complex than facial recognition.

    Many healthcare workers know that washing hands is important to prevent the spread of infectious disease. During a study conducted by Nicas and Best at Berkley University, they counted the number of times people touched their face with their hands. Whether we are aware of our actions or not, most of us can agree that we touch our face with our hands frequently enough.

    Imagine that you are able to record a full day of your actions. Better yet, reflect on what you did when you woke up yesterday morning. Let me give you an idea of my previous morning. I was woken by the alarm clock at 6 am.Then I checked my phone for messages, turned on the TV for my morning news, started making my coffee and finally hit the shower. It wasn't even 5 minutes from the time I awoke and I already touched different objects. The point of this is to be aware that even in our homes we are exposed to germs in places we don't realize.

    Luckily, the human body has amazing defense against harmful germs. Our white blood cells are like soldiers coming to the rescue. Unfortunately, there are a lot of areas on our face that do not have the protection of skin such as the eyes and mouth. There's a reason to every wise proverb and our parents annoying us to wash our hands before dinner is not for nothing.

    If you have children, it is even more important to set the example because children often learn from adults. Let's start a good habit of washing hands. As for your friends, don't be shy about checking to make sure their hands are clean. Asking someone if they have washed their hands is caring. Checking to see if someone has washed their hands will benefit not only that person but also you and your family.

A. Our skin is the first line of defense.

B. Several minutes later, I turned off the alarm clock.

C. It is easy for us to admit that we wash our hands regularly.

D. They are more self-aware that hand washing should be practiced as needed.

E. Most importantly, it is our duty to set the right example for friends and family.

F. They found that the subjects touched their face 15.7 times per hour on average.

G. Do the rest of your family members, especially children, wash their hands regularly?
