I call my story the story of a bad boy, partly to distinguish myself from those faultless young gentlemen, and partly because I really was not an angel. I may truthfully say I was a friendly, impulsive(易冲动的)teenager. I didn't want to be an angel. In short, I was a real human boy, such as you may meet anywhere in New England.

Whenever a new scholar came to our school, I used to ask him "My name's Tom Bailey; what's your name?" If the name struck me favorably, I shook hands with the new pupil cordially, but if it didn't, I would turn and walk away, for I was particular on this point.

I was born in Rivermouth almost fifty years ago, but, before I became very well acquainted with that pretty New England town, my parents moved to New Orleans. I was only eighteen months old at the time of the move, and it didn't make much difference to me where I was, because several years later, when my father proposed to take me North to be educated, I had my own view on the subject. I instantly kicked over the little boy, Sam, who happened to be standing by me at the moment, and declared that I would not be taken away to live among a lot of Yankees! You see I was what is called "a Northern man with Southern principles," I had no recollection of New England: my earliest memories were connected with the South. I knew I was born in the North, but hoped nobody would find it out. I never told my schoolmates I was a Yankee, because they talked about Yankees in a scornful way which made me feel that it was quite a shame not to be born in the South.

And this impression was strengthened by Aunt Chloe, who said, "There wasn't no gentlemen in the North no way."

    With this picture of Northern civilization in my eye, the readers will easily understand my terror at the bare thought of being transported to Rivermouth to school, and possibly will forgive me for kicking over little Sam, when my father announced this to me. As for kicking little Sam, I always did that, more or less gently, when anything went wrong with me.

    My father was greatly troubled by this violent behavior. As little Sam picked himself up, my father took my hand in his and led me thoughtfully to the library. He appeared strangely puzzled on learning the nature of my objections to going North.

"Who on earth, Tom, has filled your brain with those silly stories?" asked my father calmly.

"Aunt Chloe, sir, she told me."

My father devoted that evening and several evenings to giving me a clear account of New England: its early struggles, its progress, and its present condition. I was no longer unwilling to go North; on the contrary, the proposed journey to a new world full of wonders kept me awake nights. Long before the moving day arrived I was eager to be off. My impatience was increased by the fact that my father had purchased for me a fine little Mustang pony, and shipped it to Rivermouth two weeks before the date set for our own journey. The pony completely resigned me to the situation. The pony's name was Gitana, which is the Spanish for "gypsy", so I always called her Gypsy.

    Finally the time came to leave the vine-covered mansion among the orange-trees, to say goodbye to little Sam(I am convinced he was heartily glad to get rid of me), and to part with Aunt Chloe. I imagine them standing by the open garden gate; the tears are rolling down Aunt Chloe's cheeks; they and the old home fade away. I am never to see them again!

    Whether in the home or the workplace, social robots are going to become a lot more common in the next few years. Social robots are about to bring technology to the everyday world in a more humanized way, said Cynthia Breazeal, chief scientist at the robot company Jibo.

    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.

The situation is that familiar — deadlines are approaching, time runs out, disorder and confusion fills the day. The feeling is just as familiar — a slightly faster heart rate, and shortness of breath. Yes, it is panic time.

    It's too late to kick yourself with "I should have started on this sooner." or "It was a mistake to accept this tight deadline." The only thing left to deal with the situation is to panic more efficiently.

    ① Focus.

Panic happens when you are on an overload — too many things to do, too much pressure, too little time. But if you focus on the tasks that you need to take care of, and line them up in a logical list, you can have better control of a highly stressful and wild situation.

    ② Get rid of distractions.

    Time wasters and unnecessary activities are the last things you need during this time. Let everyone know you are on panic mode and should not be disturbed unless it is an emergency.

    ③ Watch your time.

    Don't be too engaged in one detail so that you reduce your timing for the other important details. Mind the time and deal with each task so that you can finish all of the required activities sufficiently.

    Try to solve a panic situation as quickly as you can so that you can rest and get back your energy and strength for the next one.

    As an oceanographer（海洋学家）, I've spent many years developing robots to explore the ocean, and now we're putting that technology to use in our JASON Project, a program that's designed to inspire students and get them interested in science, technology, engineering and mathematics. In theaters throughout the country, we bring kids together and send back to them on large screens our live explorations of large areas of the globe. Not only are the kids observers, but they can operate robots moving across the area while broadcasting images back to them. The kids have the sensation（感受） of really being at the site with us.

    I believe advances in robot technology will one day be the key to a new kind of travel. In the next 10 or 15 years, people will have rooms in their houses that will be able to simulate (模拟) other environment. I like to call this rooms “home domes” -- small theaters with screens and advanced equipment that can reproduce the sights, sounds, smells, and feel of a desert, or a forest. Hand in hand with these rooms, I can see a market for travel robots located in countries around the world. You could rent (租)a robot working in a rain forest, then go into your home dome, where you yourself operate the robot's movements. The equipment in the room will receive the sensations in the robot's environment and simulate them for you.

    Today, much of the world's population never travels more than 50 or 60 miles from home. And even a person with enough time can see only a part of the earth's sights. But this new way of travel will cost so much less in both time and money and allow people to see a lot more of the globe. And simulated travel will also help protect our planet. You can't take large groups of tourists to look at Dian Fossey's gorillas（大猩猩）. But a small robot, with no animal smell, can get very close to a gorilla and send the sights, sounds, and smells back to a million people.

    After disappearing for over 19 years, measles (麻疹) is making a comeback in America. Since January 2019, the disease has infected more than 700 people, mostly small children, and the number seems to be increasing daily.

    Measles is an infectious disease that typically begins with a high fever, cough, runny nose, and red, watery eyes. Many people also lose their appetites and feel sleepy. About three to four days after the symptoms start, the person breaks out into a rash (皮疹) that begins on the face at the hairline and then spreads to the neck and the rest of the body.

    In healthy people, the recovery, which takes between two to three weeks, starts soon after the rash begins. However, for about 40 percent of patients — mainly kids under the age of five or older adults — the disease often leads to pneumonia (肺炎), which, if left untreated, could result in death.

    The recent outbreak is thought to have been caused by travelers picking up the virus in a country where the disease is still existing and exposing it to an unvaccinated (未接种的) community in the US. In New York, it was carried back by someone who had recently visited Israel, which is currently undergoing a significant measles, while in Washington, "patient zero" was infected by a type that is currently circulating in Europe.

    To limit the spread of the disease before it gets out of hand, US health officials are attempting to educate communities with high rates of unvaccinated children. They are also urging adults to consult with their physicians and get injected if considered necessary by the doctor.

    Hopefully, health officials worldwide will be able to convince parents that vaccinating their children will protect, not harm, them.

    People have strange ideas about food. For example, tomato is a kind of very delicious vegetable. It is one of useful plants that can be prepared in many ways. It has rich nutrition(营养) and vitamin in it. But in the 18th century, Americans never ate tomatoes. They grew them in their gardens because tomato plants are so pretty. But they thought the vegetable was poisonous(有毒的). They called tomatoes "poison apples".

    President Thomas Jefferson, however, know that tomatoes were good to eat. He was a learned man. He had been to Paris, where he learned to love the taste of tomatoes. He grew many kinds of tomatoes in his garden. The President taught his cook a way for a cream of tomato soup. This beautiful pink soup was served at the President party. The guests thought the soup tasted really good. They never thought their president would serve his honored guests poison apples. Jefferson never spoke to his honored guests about the fact.
