My mom takes pride in the fact that I was talking in three and four word sentences before I was ten months old. Some say it's a gift while others simply think I talk too much.

    As my thirties came to a close, I found myself reflecting on my life. I'm very happy and have no significant regrets. However, when I looked back on those times of difficulty, I saw a clear common denominator(特征); I didn't seem to know when to stop talking. Whether it was hurting someone's feelings, or having carelessly told a secret, the incident could have been avoided had I closed my mouth sooner. So I decided to practice the power of quiet.

    To take this step, I needed to understand how people could sit comfortably in a group and not talk. Why does my husband feel completely content to say nothing in a conversation? He's highly intelligent and has wonderful opinions but he'll sit quietly and just listen. Even when he's asked a pointed question, he'll answer with few words while still communicating effectively. What a talent!

    Can you imagine being happy just listening? In surveying those I know who talk less than I do, I got two answers—they either didn't feel confident enough to speak up, or they just didn't feel the need to participate in the conversation. Of course there were other reasons for not talking, but these were the two most popular answers.

    The first one didn't work for me. I'm just fine letting people know what I think about them, and hopefully it will make the conversation much more interesting. The second one didn't work either. I do feel the need to participate. I feel it physically like an electrical pulse through my body; sometimes it's so strong that it causes me to behave badly in the form of interrupting or speaking in an unusually loud voice. I had to look further.

    An interesting thing happened on this journey to the power of quiet. During my weekly yoga class, it came to me like an answer so clear that the words rang in my head like soft, heavenly bells.

    I talked too much so people would know I cared about them. It was my way of taking care of those I love. I decided before my fortieth birthday, that from that day forward, those around me would know I loved them, and cared what they thought and felt, but I was going to practice the power of quiet.

    As my forty-second birthday approaches, I can say that deciding to talk less has been more about focusing on quality rather than quantity. I've found that listening more shows those who I care about that I really do care how they feel. Now when I break in, it means more to them. Oh, sure, I still have my short periods of talking too much, but for the most part this has been one resolution that I can call a success.

    One of my wonderful memories is about a Christmas gift. Unlike other gifts, it came without wrap(包装).

    On September 11th, 1958, mum gave birth to Richard. After she brought him home from hospital, she put him in my arms, saying, “I promised you a gift, and here it is.” What an honor! I became four years old a month earlier and none of my friends had such a baby doll of their own. I played with it day and night. I sang to it. I told stories. I told it again and again how much I loved it!

    One morning, however, I found its bed empty. My doll was gone! I cried for it. Mum wept(哭泣) and told me that the poor little thing had been sent to a hospital. It had a fever. For several days, I heard mum and dad whispering such words as “hopeless”, “pitiful”and “dying”, and all these words sounded ominous.

    Christmas was coming. “Don't expect any presents this year,” Dad said, pointing at the socks I hung in the living rooms. “If your baby brother lives, that'll be Christmas enough.” As he spoke, his eyes filled with tears. I had never seen him cry before.

    The phone rang early on Christmas morning. Dad jumped out of bed to answer it. From my bedroom I heard him say, “What? He's all right?”He hung up and shouted upstairs. “The hospital said we can bring Richard home!”

    “Thank God!” I heard mum cry.

    From the upstairs window, I watched my parents rush out to the car. I had never seen them so happy. And I was also full of joy. What a wonderful day! My baby doll would be home. I ran downstairs. My socks still hung there flat. But I knew they were not empty：they were filled with love!

    Many people believe that language belongs to human beings. However, cats have developed a language not for each other, but for the human beings who have them as pets.

    When communicating with each other, cats “talk” with a system of signals. Their tails, rather than any kind of “speech”, act as an important way to express themselves. They also touch each other to express s their feelings. With other cats, they will use their voices only to express pain. Unbelievable, all of that changes when a human walks into the room. Cats use many different kinds of vocal (声音的) expressions when they communicate with a person. Since these vocal expressions are not used to communicate with other cats, it seems that cats developed this “language” to communicate with their human owners.

    This fact is shown more clearly when watching rooms that have only one cat and those with several cats. An only cat is usually very vocal, since the only creature(动物)around with whom the cat can communicate is its owner. Cats with other cats, though, are much quieter. If they want to have a conversation, they only need go to other cats and communicate in their natural way.

    Since cats learned to meow(喵喵叫)for the only purpose of communicating with human owners should take the time to learn what their different meows mean. If an owner knows, to name just a few examples, which meow means the cat is hungry, which means the cat wants to be petted, and which means the cat wants to have a little “conversation”, the relationship between cat and owner will be closer.

    I began to grow up that winter night when my parents and I were returning from my aunt's house, and my mother said that we might soon be leaving for America. We were on the bus then. I was crying, and some people on the bus were turning around to look at me. I remember that I could not bear the thought of never hearing again the radio program for school children to which I listened every morning.

    I do not remember myself crying for this reason again. In fact, I think I cried very little when I was saying goodbye to my friends and relatives. When we were leaving I thought about all the places I was going to see—the strange and magical places I had known only from books and pictures. The country I was leaving and never to come back was hardly in my head then.

    The four years that followed taught me the importance of optimism（乐观）, but the idea did not come to me at once. For the first two years in New York I was really lost—having to study in three schools as a result of family moves. I did not quite know what I was or what I should be. Mother remarried, and things became even more complex for me. Some time passed before my stepfather and I got used to each other. I was often sad, and saw no end to “the hard times.”

    My responsibilities in the family increased a lot since I knew English better than everyone else at home. I wrote letters, filled out forms, translated at interviews with Immigration officers（移民局官员）, took my grandparents to the doctor and translated there, and even discussed telephone bills with company representatives.

    From my experiences I have learned one important rule: Almost all common troubles go away at last! Something good is certain to happen in the end when you do not give up, and just wait a little! I believe that my life will turn out all right, even though it will not be that easy.

The Rapid Rise and Fall of Robot Babysitters

    During the winter of 2017, an 18-year old college student named Canon Reeves spent much of his time trailing a knee-high robot around Fayetteville, Arkansas, as it delivered Amazon packages to students. The robot, created by a start-up called Starship Technologies in 2014, is basically a cooler on wheels; it uses radars, sensors, and nine cameras to make deliveries. Reeves's job was to monitor how it handled various grounds, field comments from the public, and press the off switch if necessary. He said, "People would also ask if it could deliver beer." It couldn't.

    Broadly speaking, jobs of caring for robots fall under the umbrella of careers in automation, which include maintenance, engineering and programming. The demand for people with this skill set is considerable, with 20 million to 50 million new jobs to be expected in this category by 2030, according to the Mckinsey Global Institute. In the year that ended in June 2018, Indeed.com had almost three times the number of positions on the recruitment committee that ended in June 2016.

    Over the last year, a 34-year-old businessman named David Rodriguez spent hundreds of hours following a machine called the KiwiBot around UC Berkeley's campus while it delivered Red bull and other drinks to students. To retrieve (检索) orders, the app encourages students to give the robot a wave; the robot's digital eyes will roll depending on its mood. Rodriguez, who heads business development for the start-up, was tasked, early on, with monitoring the KiwiBot for problems – even carrying it, should the motors fail. Since April 2018, though, the KiwiBot has largely been left unattended, and the majority of human interactions involve technical checks and loading food into the robot. To eliminate the boring work, the team is developing a restaurant robot to collect and load orders – which could happen in 2020. However, Rodriguez assured me that his staff won't be out of work. Everyone holds double roles in the company. Greater robot self-governing just means employees will shift their focus to accounting, engineering, and design.

    Mckinsey estimates that millions of jobs globally could be lost to automation by 2030. "A huge number of jobs will be produced as autonomous vehicles are released into the environment," Ramsey said. In 2016, Bosch started training students from Schoolcraft College, a community college in Michigan, in autonomous-vehicle repair; Toyota has trained students in maintenance as well. "We might even see a return to low-level jobs where people come and fuel the car for you," Ramsey said. "Until we can wirelessly charge, someone needs to refuel them." The hardest-to-automate industries, as it happens, are the ones that require looking after humans, such as childcare, education and health care. Robot babysitters might feel like they have scored the job of the future, but in fact, they might be better positioned.

    When we are young we are taught that it's wrong to lie and we should always tell the truth. Unfortunately, most children lie even if they're told not to. Research carried out at the Institute of Child Study at Toronto University has shown that this might not be such a bad thing. Apparently (显然地), children who tell lies when they're two years old have a good chance of becoming successful adults (成年人).

    According to the research, at the age of two, 20 percent of children lie. At the age of three, 50 percent lie, and at four almost 90 percent lie. By the age of 12 almost every child tells lies.

    Lying needs much brain work. And the better the lie is, the more work the brain has to do. By training the brain early, researchers believe children will be able to think more clearly when they are adults.

    Recent research, carried out by the Science Museum in London, has shown some interesting facts about the way we lie as adults. According to the research, the average British man tells three lies every day, that's over 1,000 lies a year. However, the average woman apparently only lies twice a day.

    Most people think women are better liars (说谎者) than men although in fact they tell fewer lies. Popular women's lies include 'Nothing's wrong, I'm fine', 'I don't know where it is, I haven't touched it', and 'It wasn't that expensive'.

    Some people say you can lie as long as it's a white lie. A white lie is a lie told to avoid hurting someone's feelings. One of the most common lies for both men and women is 'It's just what I've always wanted', said after opening a present from their partner.
