As a little child, I was always plump（胖的）. In college I started blowing up. It got out of control when l went to law school.

    I'd made a decision a thousand times: I'm going to lose weight now. But what motivated（激发） me to get serious about it was turning 30.1 weighed 414 pounds.1 was always tired. Some of my family members have suffered from heart disease, and l was frightened. I also wanted to look better.

    So after my birthday, I walked into the office of a weight loss doctor.

    She was very understanding. Her focus was on balanced meals and she wanted me to exercise.

    Walking was all I could do at first. I started by walking a few blocks and gradually increased the distance, until one weekend, I heard myself saying, "Wow, this seems pretty easy." So I started to run.

    I was losing nine or ten pounds a month, and I had more energy. I started to think about the New York City Marathon. For years, I watched the runners and thought, "This looks like fun, but I could never do that." But now I realized that maybe I could. I joined the New York Road Runners. I ran a 10km, then a half marathon.I still wasn't confident I could run a full 26 miles. But I told myself I was going to do it, no matter what.

    By my 33rd birthday, I was down to 180 pounds. I started formally training for the marathon.

    And on the morning of November l, I stood on the Verrazano Bridge in Staten Island with more than 40,000 0ther runners, waiting for the event to start.

    It was unbelievable to have the audience cheering me on, handing me cups of water. And I crossed the finish line. My friends sprayed（向……喷射）me with beer, as if I'd won the Super Bowl.

    And at that moment, I knew: If I set my mind to something, nothing is impossible.

    Recently some American scientists have given a useful piece of advice to people in industrialized nations．They say people should eat more of the same kind of food eaten by humans living more than 10,000 years ago．{#blank#}1{#/blank#}

    The scientists say that the human life has changed greatly．Our bodies have not been able to deal with these changes in lifestyle and this had led to new kinds of sicknesses．{#blank#}2{#/blank#} So they are called "diseases of civilization"．Many cancers and diseases of the blood system are examples of such diseases.

    Scientists noted that people in both the Old Stone Age and the New Stone Age enjoyed very little alcohol or tobacco, probably none．{#blank#}3{#/blank#} However, a change in food is one of the main differences between life in ancient times and that of today.

    Stone Age people hunted wild animals for their meat, which had much less fat than domestic ones．They ate a lot of fresh wild vegetables and fruits．They did not have milk or any other dairy products, and they made very little use of grains．{#blank#}4{#/blank#} We eat six times more salt than our ancestors．We eat more sugar．We eat twice as much fat but only one third as much protein and much less vitamin C.

    {#blank#}5{#/blank#} But scientists say that we would be much healthier if we eat much the same way the ancient people did, cutting the amount of fatty, salty and sweet food.

 A．Modern people used to suffer from "diseases of civilization".

 B．People today probably don't want to live like our ancestors.

 C．These new sicknesses were not known in ancient times.

 D．Ancient people also got lots of physical exercise.

 E．In that case, they would live much healthier.

 F．But today, we enjoy eating a lot of these.

 G．Stone Age people lived a simple life.

    When I graduated from college I dreamed of being a television news reporter. Having no experience, I had to work in a small town until I finally got my big break in the form of a job in Boston. I made it.

    Soon, reality set in. I was too often sent to run after accused criminals out of courts, waiting outside of crime scene tape or at the doorstep of a family still crying for tragedy (悲剧). My breaking point came the day I accidentally informed a young woman that her mother died. It was the worst day of my professional life and the day I decided I no longer wanted to shine a light on these stories. My career was ebbing, and at the same time my personal life was too-I divorced.

    My mom had always told me “When you're feeling extremely upset, go help someone else.” So I started seeking out stories of people who had been in the news under tragic circumstances but were doing something inspiring with their lives: a young girl who was paralyzed (瘫痪的) by an accident but was uplifting her classmates with her positive spirit, a blind and autistic (自闭的) musician who learned to play 27 instruments, a disabled soldier who opened his own art studio. I started to tell and promote stories like them.

    Over the last 10 years I have discovered my kindness gift: my ability to see the beautiful side of a person and reflect it back to them and the world. In telling stories of people turning their own hurt into acts of helping others I have become more sympathetic, more grateful and kinder. I have learned kindness is who we are, that our power for it is limitless and that, as we shine a light on it, it grows.

    In our daily life, it is necessary to make small talk in some situations. It helps to fill time between people when it is very quiet. You may not feel like talking with someone else or you are very shy at the beginning, but it is sometimes thought to be not polite to say nothing.

    People use small talk almost every day. It usually takes place when you meet someone you don't know at all or someone you're not familiar with. For example, waiters and hairdressers often make small talk with their customers（顾客）. If you happen to be outside when the postman comes to your door, you might make small talk with him, too.

    Most often, small talk happens in places where people are waiting for something. For example, you might talk with another person who is waiting for the bus to arrive. People also make small talk in a doctor's waiting room, or when they are waiting in a line to buy something. At the office, people make small talk in lunch rooms, especially if there is a line-up. Mingling is often required（要求）among people who don't know each other very well at a party. That is to say, they are expected to walk around and talk with others.

    The most common time for small talk to happen is the first time you see or meet someone on a given day. For example, if you see a neighbor in the waiting room of the airport you might say hello and discuss the sports or weather. However, the next time you see each other you might just smile and say nothing. If there is very little noise, it might be the right time to start a pleasant conversation. If someone is reading a book at the bus stop, it is probably not a good idea to start a conversation. Another good time to make small talk is during a break in a meeting when there is nothing important going on. However, it is important to recognize the signal when the other person wants the conversation to stop.

    A new study from the Georgia Institute of Technology finds that older and younger people have a varying preference for what they would want a personal robot to look like. And they change their minds based on what the robot is supposed to do.

    Participants were shown a series of photos, either robotic, human or mixed human-robot faces, and were asked to select the one that they would prefer for their robot's appearance. Most college-aged adults in the study preferred a robotic appearance, although the others were also generally open to them. However, nearly 60 percent of older adults said they would want a robot with a human face, and only 6 percent of them chose one with a mixed human-robot appearance.

    "We found that participants, both younger and older, will assign emotional traits to a robot based on its face, which will determine what they are most comfortably interacting with," Akanksha Prakash, a psychology graduate student at Georgia Tech who led the study, said in a statement. So when participants were told the robot was helping with personal care, chores, social interaction or helping to make decisions, something interesting happened.

    Preference was less strong for helping with chores, although the majority of older and younger participants chose a robot with a robotic face. But for decision-making tasks, such as getting advice on where to invest money, younger participants tended to select a mixed human-robot appearance. A robotic face was their least favored choice for this task. Older adults generally preferred a human face. Personal care tasks such as bathing caused the most divisive preferences within both age groups. Those who chose a human face did so because they associated the robot with human-like care capabilities — such as nursing — and trustworthy traits. Many others didn't want anything looking like a human to bathe them due to the private nature of the task.

    Based on this early research, the researcher says that if a robot is designed to help only with a specific task, its appearance should fit in with the task. For instance, if the robot is designed to specifically assist the user with critical decisions, the robot should be given an intelligent look instead of a funny one. However, if the robot is tasked with a variety of jobs in the home, allowing for appearance customizability(可定制性) might be the best option.

    The researcher next plans to expand the study to other age groups and people with more diverse educational backgrounds.

    One Sunday, my son asked me if he could ride up to his elementary school on his bike and meet his friend. He wanted both of them to ride back to our house so they could play video games and jump on the trampoline (蹦床). I have to admit, part of me wanted to say no. We could go to pick him up or his parents could bring him over here. I thought. But my son is eleven years old now. And after all, I do let him ride his bike to school. But I also drive my daughter to school and I can see him on the way, making sure he is getting there safely.

    My husband thinks I am overprotective. I don't dare to let my children walk anywhere without one of us going along. As you go out of our neighborhood, there is a shopping center across the street. My son always asks if he can ride his bike or walk over to the drugstore by himself. But crossing that street is just too dangerous. The cars fly around the comer like they're driving in a car race. What if he gets hurt? What if some teenager bullies are hanging out in the parking lot? I want so much to give my children the freedom that I enjoyed having when I was growing up but I hesitate to do so, because there are dangers around every comer. Too many kidnap, too many robberies and so on.

    I honestly don't think my mom worried about such things when her children were young. Growing lip in the 1970s was indeed very different. I never wore a helmet (头盔) when I rode a bike. We were all over the neighborhood, on our bikes and on foot, coming home for dinner and then-back out again until dark. We rode in the back of the truck and didn't wear seat belts. I walked to and from school every day.
