When I was growing up, I had an old neighbor named Doctor Gibbs. He didn't look like any doctor I'd ever known. He never yelled at us for playing in his yard, but was always very kind.

    When Doctor Gibbs wasn't saving lives, he was planting trees. He had some interesting theories about planting trees. He believed in the principle “No pain, no gain”. He hardly watered his new trees, which flew in the face of conventional(传统的) wisdom. Once I asked why and he told me that watering plants spoiled them because it made them grow weaker. He said you had to make things tough for the trees so that only the strongest could survive. He talked about how watering trees made them develop shallow roots and how, if they were not watered, trees would grow deep roots in search of water. So, instead of watering his trees every morning, he'd beat them with a rolled-up newspaper. I asked him why he did that, and he said it was to get the tree's attention.

    Doctor Gibbs died a couple of years after I left home. Every now and then, I walked by his house and looked at the trees that I'd watched him plant some twenty five years ago. They were all tall and strong.

    I planted a couple of trees myself a few years ago. Two years of attending these trees meant they grew up weak. Whenever a cold wind blew, their branches trembled. Adversity(逆境) seemed to benefit Doctor Gibb's trees in ways comfort and ease never could.

    Every night before I go to bed, I check on my two sons. I often pray that their lives will be easy. But lately I've been thinking that it's time to change my prayer. I know my children are going to meet with hardship. There's always a cold wind blowing somewhere. What we need to do is to pray for deep roots, so when the rains fall and the winds blow, we won't be torn apart.

    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.

    Running is often tiring and a lot of hard work, but nothing beats the feeling you get after finishing a long workout around the track.

    But while it's long been believed that endorphins (脑内啡）—chemicals in the body that cause happiness — are behind the so-called “runner's high”，a study suggested that there may be more to this phenomenon than we previously knew.

    According to a recent study published by a group of scientists from several German universities, a group of chemicals called endocannabinoids (内源性大麻素）may actually be responsible for this familiar great feeling.

    To test this theory, the scientists turned to mice.

    Both mice and humans release high levels of endorphins and endocannabinoids after exercise, along with many other chemicals. After exercising on running wheels, the mice seemed happy and relaxed and displayed no signs of anxiety.

    But after being given a drug to block their endorphins the change. However, when their endocannabinoids were block with a different drug, their runner's high symptoms seemed to fade.

    “The long-held notion of endorphins being responsible for the runner's high is false. Endorphins are effective pain relievers, but only when it comes to the pain in your body and muscles you feel after working out,”Patrick Lucas Austin wrote on science blog Lifchacker.

    Similar studies are yet to be carried out on humans, but it's already well known that exercise is a highly effective way to get rid of stress or anxiety.

    The UK's National Health Service even prescribes (开药方)exercise to patients who are suffering from depression.

    “Being depressed can leave you feeling low in energy, which might put you off being more active. Regular exercise can boost your mood if you have depression, and it's especially useful for people with mild to moderate (中等的）depression,” it wrote on its website.

    It seems like nothing can beat that feeling we get after a good workout, even if we don t fully understand where it comes from. At least if we're feeling down, we know that all we have to do is put on our running shoes.

    Three important changes that will affect people's everyday life in the future.

    The cashless society

    Cash and bank notes will disappear almost completely. They will be replaced by smart cards with microchip (微芯片) "loaded" with some money. When we pay for goods, we will put our smart cards into a payment terminal (终端) and money will be transferred (转) from our cards to the retailer's (零售商的) card. When all the money is used up, we will be able to "reload" it by inserting it into a telephone, dialing our bank account and putting money to the card from the account. If we want to transfer money from our cards to a bank account, we will use the same method. Smart cards will be able to hold several different currencies at the same time. So if we go abroad, we will be able to use our smart cards in the same way.

    Interactive telephones

    Human telephones will be replaced by talking computers. These computers will recognize speech, ask us what information we need, find the information and change it to speech. If we want to book a flight or pay a bill by phone, we will ask a talking computer to do it. Of course, this won't happen until all the technology is in place, but when it is we will soon get used to using computers in this way.

    ________________

    Traffic congestion (拥挤) in cities will be reduced because drivers will use electronic maps to find the quickest way to their destinations and avoid traffic jams. Because people have to pay to drive in cities, they will stop using their cars and use public transport instead. Speed control systems will be built into cars. These systems will control the speed of the car according to the traffic and weather conditions and prevent accidents.

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

    On September 11^th, 1958. Mum gave birth to Richard. After she brought him home from hospital, she put him in my lap, saying. "I promised you a gift, and here it is." What an honor! I turned four 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 it stories. 1 told it over and over how much I loved it!

    One morning, however, I found its bed empty. My doll was gone! I cried for it. Mum wept 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", which sounded ominous.

    Christmas was coming. "Don't expect any presents this year." Dad said, pointing at the socks I hung in the living room. "If your baby brother lives, that'll be Christmas enough." As he spoke, his eyes filled with tears. I'd 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 happy. And I was also full of joy. What a wonderful day! My baby doll would be home. I downstairs. My sacks still hung there flat. But I knew they were not empty; they were filled with love!
