More and more people like bicycling and it is no surprise. It is fun, healthy and good for the environment. Maybe that's why there are 1.4 billion bicycles and only 400 million cars on roads worldwide today. Bikes can take you almost anywhere, and there is no oil cost!

    Get on a bicycle and ride around your neighbourhood. You may discover something new all around you. Stopping and getting off a bike is easier than stopping and getting out of your car.

    You can bike to work and benefit (受益) from the enjoyable exercise without polluting  the environment. You don't even have to ride all the way. Folding (折叠) bikes work well for people who ride the train. Just fold the bike and take it with you. You can do the same on an airplane. A folding bike can be packed in a suitcase. You can also take a common bike with you when you fly. But be sure to look for information by getting on airline websites. Not all airlines are bicycle-friendly to travellers.

Health Benefits of Bicycling:

    It helps to prevent heart diseases.

    Bicycling helps to control your weight.

    A 15-minute bike ride to and from work three times a week burns off five kilos of fat in a year.

    Bicycling can improve your mood (心情).

    Exercise like bicycling has been shown to make people feel better, more relaxed and self-confident.

    Bicycling is healthier than driving.

    On a stormy day last August, Tim heard some shouting. Looking out to the sea carefully, he saw a couple of kids in a rowboat were being pulled out to sea.

Two 12-year-old boys, Christian and Jack, rowed out a boat to search a football. Once they'd rowed beyond the calm waters, a beach umbrella tied to the boat caught the wind and pulled the boat into open water. The pair panicked and tried to row back to shore. But they were no match foritand the boat was out of control.

    Tim knew it would soon be swallowed by the waves.

“Everything went quiet in my head,” Tim recalls（回忆）. “I'm trying to figure out how to swim to the boys in a straight line.”

    Tim took off his clothes and jumped into the water. Every 500 yards or so, he raised his head to judge his progress. “At one point, I considered turning back,” he says. “I wondered if I was putting my life at risk.” After 30 minutes of struggling, he was close enough to yell to the boys, “Take down the umbrella!”

    Christian made much effort to take down the umbrella. Then Tim was able to catch up and climb aboard the boat. He took over rowing, but the waves were almost too strong for him.

“Let's aim for the pier（码头）,” Jack said. Tim turned the boat toward it. Soon afterward, waves crashed over the boat, and it began to sink. “Can you guys swim?” he cried. “A little bit,” the boys said.

Once they were in the water, Tim decided it would be safer and faster for him to pull the boys toward the pier. Christian and Jack were wearing life jackets and floated on their backs. Tim swam toward land as water washed over the boys' faces.

    “Are we almost there?” they asked again and again. “Yes,” Tim told them each time.

    After 30 minutes, they reached the pier.

    “Indeed,” George Washington wrote in his diary in 1785, “some kind of fly, or bug, had begun to eat the leaves before I left home.” But the father of America was not the father of bug. When Washington wrote that, Englishmen had been referring to insects as bugs for more than a century, and Americans had already created lightning-bug(萤火虫). But the English were soon to stop using the bugs in their language, leaving it to the Americans to call a bug a bug in the nineteenth and twentieth centuries.

    The American bug could also be a person, referring to someone who was crazy about a particular activity. Although fan became the usual term, sports fans used to be called racing bugs, baseball bugs, and the like.

    Or the bug could be a small machine or object, for example, a bug-shaped car. The bug could also be a burglar alarm, from which comes the expression to bug, that is, “to install (安装) an alarm”. Now it means a small piece of equipment that people use for listening secretly to others' conversation. Since the 1840s, to bug has long meant “to cheat”, and since the 1940s it has been annoying.

    We also know the bug as aflawin a computer program or other design. That meaning dates back to the time of Thomas Edison. In 1878 he explained bugs as “little problems and difficulties” that required months of study and labor to overcome in developing a successful product. In 1889 it was recorded that Edison “had been up the two previous nights discovering ‘a bug' in his invented record player.”

    I sit on the stoop (门廊) in front of my friend's house at the top of a steep hill. And now my friend is late, and I'm stuck here waiting.

    I see a man approaching.

    "Por favor. Call 911," the man says. "Finger. Cut." With his left hand, he is pressing the handkerchief around his right little finger.

    "No. Have. Phone," I say, as if English is also my second language.

    "Have phone," he says, and dips his chin toward his front pants pocket. There, I find a phone, and call 911.

    The operator answers, and I say "I'm with this guy, and he cut his finger."

    "Did he cut it off?"

    "Did you cut it off?"

    "Sí." He sighs.

    "Yes. He cut it off."

    "Where is it?" the operator asks.

    "Where is it?"

    "Upstairs," he says, pointing with his elbow to the house next door.

    "Go get it," she instructs me.

    I follow the man toward the house. Inside, I see a table saw(锯), and the blood spreading across the ceiling, but I don't see the finger. I lift up each foot and look underneath to be sure I've not stepped on it. I'm getting that jumpy, tight-shouldered feeling like when you've lost sight of a spider that was on your ceiling a moment ago.

    "Do you see it?" I ask him.

    He points at his own finger beside the table saw. I grab a paper towel, pinching it carefully, the way you might pick up a harmless but frightening insect.

    "We have secured the finger," I tell the operator.

    "Hang tight. The ambulance is on its way."

    We sit on the stoop waiting for the ambulance.

    "You're going to be OK," I say, putting my free hand on his sawdust-covered back.

    "Gracias," he says.

    "De nada. Esta no problemo," I reply in broken Spanish.

    It feels good to be able to comfort someone, anyone. For months now, the second my hands would go idle(闲散的), a familiar depression would climb on my back. I have been trying to put on a good face for my kid, but I feel as if I've been failing. Could I save myself? I wouldn't know how. But I am determined to save this man.

    Finally the ambulance arrives, picks him up, and they're off.

    Throughout the evening, I can't stop worrying about the man. I decide to call the hospital.

    "Hi! I helped a guy who cut off his finger, and I don't even know his name, but I'm wondering whether he came to your hospital."

    The nurse says, "His name is Jose Ramos, and he's waiting for surgery. Would you like to leave a message?"

    "No. I don't want to bother him. I just wanted to be sure he was OK."

    The next morning, I call the hospital again. This time, I'm put through to Jose's room. "How was the surgery?"

    "No surgery," he says. "No enough blood."

    "Oh, I'm sorry," I say.

    Later that day, I remember that old proverb about how if you save someone's life, you are responsible for them for the rest of their life, which never made sense to me before. Shouldn't the person who got saved owe a debt, and not the other way around? But today, I get it. It's a great honor to help someone in need.

    I start keeping a lookout for other people in need of assistance. I help push a stalled car out of the road. I aid a disoriented cyclist when her bike gets clipped by a car. I adopt a dog. Then one day, a month or two after the finger incident, I realize I have completely forgotten to be depressed. I've been so busy playing the role of local hero that I have ignored to drag my feet and stare into space and imagine the world without me.

    Now, more than a decade has passed since Jose's accident. Occasionally I search for "Jose" plus "Ramos" plus "finger." I wish I could see him again, to see how he's getting on. But more important, to thank him, because when he lost his finger, he saved my life.

    It's really true what people say about English politeness: it's everywhere. When squeezing past someone in a narrow aisle, people say "sorry". When getting off a bus, English passengers say "thank you" rather than the driver. In Germany, people would never dream of doing these things. After all, squeezing past others is sometimes inevitable, and the bus driver is merely doing his job. I used to think the same way, without questioning it, until I started travelling to the British Isles and came to appreciate some more polite ways of interacting with people.

    People thank each other everywhere in England, all the time. When people buy something in a shop, customer and shop assistant in most cases thank each other twice or more. In Germany, it would be unusual to hear more than one thank you in such a conversation. British students thank their lecturers when leaving the room. English employers thank their employees for doing their jobs, as opposed to Germans.

    Another thing I observed during my stay was that English people rarely criticize others. Even when I was working and mistakes were pointed out to me, my employers emphasized several times but none of their explanations were intended as criticism. It has been my impression that by avoiding criticism, English people are making an effort to make others feel comfortable. This also is showed in other ways. British men still open doors for women, and British men are more likely to treat women to a meal than German men.
