During my free time one day, I wandered down a lonely path into the woods and sat against a tree. Then I saw one of the camp counselors approaching me. "Oh great," I thought, since counselors were always trying to cheer you up or make you laugh.

    "Hey," he said, "mind if I have a seat?" I shrugged(耸肩). I wasn't going to encourage him, but I couldn't exactly stop him, either. He sat down alongside me and extended a hand. "I'm Gary," he said, "and you're Erica, right?" I nodded. "You don't exactly look like you're having a good time," he began.

    I crossed my arms and gritted my teeth. "Look," I said, "I didn't want to come to camp, I don't like it, I'm not having fun, and it basically stinks." I glared at Gary.

    "So there's nothing here at all for you, huh?" he asked.

    "Nothing," I answered.

    "Let me show you something," said Gary. He got up, and I followed him along the path until I heard a sound like a roaring freight train.

    "What's that?" I asked.

    "Wait and see," he replied, with a small smile.

    When we rounded the corner, I couldn't believe what I saw. There was the biggest waterfall I could ever imagine, right in front of me. "Cool!" I said, and I could feel my eyes getting bigger and a smile tugging at my mouth.

    "Still think there's nothing here for you?" asked Gary. "Because there's a whole lot more of this kind of 'nothing' around here." I had to admit, the waterfall was impressive.

    "Look," said Gary, "camp is what you make it. You can be sullen(阴郁的) and closed-minded and have a rotten four weeks, or you can take a look around you and see some of the incredible sights and appreciate the opportunity. It would be useless for me to try to make you have fun. You can only do that for yourself. But if you loosen up a little, you might actually have a good time." With that, he turned and walked away, leaving me on the path.

    That night, by the campfire, I found myself singing along with everyone else. By the time the four weeks were up, I didn't want to leave. I'd seen some amazing things and made some great friends.

    Beauty is where you find it. Life is what you make it. I think it's going to be a good year this year. I mean, I'm going to work to make it one. Maybe if I'm lucky, I'll get to go back to camp next year!

    Golden Gate Bridge

    Located in San Francisco,the Golden Gate Bridge started in the year 1933 to connect the San Francisco Peninsula with Marin County.It was finally thrown open to public traffic in 1937.It cost $25.7 million in the construction.Till the year 1957,the Golden Gate Bridge,at a length of 2,737 meters,was the longest suspension bridge in the world.

    Brooklyn Bridge

    The Brooklyn Bridge is located in Brooklyn.It is one of the oldest suspension bridges in the United States, having been opened in the year 1883.The length of the bridge is 1,843 meters.The bridge has been featured in several Hollywood movies.

    George Washington Bridge

    Also known as the Hudson River Bridge and the Columbus Bridge,the George Washington Bridge which connects Fort Lee to Manhattan came into use in 1931 after a construction period of almost 4 years.It is a two level suspension bridge that cost about $52 million to build.

    Mackinac Bridge

    This is the third biggest suspension bridge in the world at a length of 8,038 meters.The architect of this bridge was Dr.David B. Steinman who directed the construction of the bridge which started in the year 1054 and opened to the public in 1958.People using this bridge are charged a certain amount of money.

    Navajo Bridge

    Located in Arizona,this bridge crosses the Colorado River and is almost 250 meters long.The construction of this bridge started in the year 1927,ending two years later,costing $390,000.In the 1990s a second bridge was built which was opened to the public in 1994.The first bridge is now used only by pedestrians.

    Last summer I sat at a long picnic table near a breathtaking mountain. While the parents were eating dinner, the kids ran up a trail in search of a secret fort. Twenty minutes later one excited little boy, James, interrupted the adult conversation.

    “Mom, Mom, you can't believe what we found!”

    Lovingly, his mother smiled and whispered, “I can't wait to hear, James, but grown-ups are talking, and there will be a pause in the conversation. Please wait for the pause.”

    On my other side, another boy came running up to his mother with equal enthusiasm.

    “Mom, Mom, we had so much fun—”

    “I am talking! Don't interrupt,” she said.

    “But, Mom—”

    “Be quiet! Can't you see that I am talking?”

    “But Mom we found the—”

    “Shut up, Steve!” she yelled.

    My heart sank. I knew what was coming. James, on my right, patiently waited for the pause, enthusiasm still alive and well. Steve, on my left, walked away from the table, looking shamed, carrying with him stories of secret forts never to be shared.

    What markedly different messages to the child! “Wait for the pause” versus “Shut up” gets incorporated (包含)so differently into a child's developing sense of self.

    Harsh(刺耳的) words have bad effects. That's why I want you to promise to delete the phrases “Shame on you” or “You should be ashamed” from your vocabulary. I have seen countless patients whose parents' thoughtless words echoed in their heads and chipped(消除) away at their self-worth, even decades later.

    So we have to discipline ourselves to make our instructions constructive. One great tool is to look for positive behavior to reinforce. Don't ignore the things that your kids are doing right. Thank your children. Tell them that you noticed how they waited patiently or cleared their plate without being asked. Chances are that they will do it again. Let them feel noticed, appreciated, and valued. There's no better way to shape behavior.

    Does this situation seem familiar to you? Your English is progressing well, the grammar is now familiar, the reading comprehension is no problem, you are communicating quite fluently, but: Listening is STILL a problem! First of all, remember that you are not alone. Listening comprehension is probably the most difficult job for almost all learners of English as a foreign language. The most important thing is to listen as often as possible. The first step is to find listening resources. The Internet is really a useful tool for English students. You can download The RealPlayer from RealMedia.com. The RealPlayer allows you to use the Internet like a radio station.

Once you have begun to listen on a regular basis, you might still be frustrated (懊恼) by limited understanding. What should you do?

    Here is some of the advice I give my students:

    Accept the fact that you are not going to understand everything.

    Stay relaxed when you do not understand — even if you continue not to understand for a long time.

    Do not translate what you hear into your native language.

    Listen for the general idea of the conversation. Don't concentrate on detail until you have understood the main ideas.

    I remember the problems I had in understanding spoken German when I first went to Germany. In the beginning, when I didn't understand a word, I insisted on translating it in my mind. This method usually resulted in confusion. Then, after the first six months, I discovered two very important facts. Firstly, translating creates a wall between the listener and the speaker. Secondly, most people repeat themselves constantly. By remaining calm, I noticed that — even if I didn't pay much attention, I could usually understand what the speaker had said.

    “Who made your T-shirt?” A Harvard University student raised that question. Piertra Rivoli, a professor of business, wanted to find the answer. A few weeks later, she bought a T-shirt and began to follow its path form Texas cotton, to Chinese factory and to charity bin (慈善捐赠箱). The result is an interesting new book, The Travels of a T-shirt in the Global Economy.

    Following a T-shirt around the world in a way to make her point more interesting, but it also frees Rivoli from the usual arguments over global trade. She goes wherever the T-shirt goes, and there are surprises around every corner. In China, Rivoli shows why a clothing factory, even with its poor conditions, means a step towards a better care for the people who work there. In the colorful used-clothing markets of Tanzania, she realizes that, “it is only in this final stage of life that the T-shirt will meet a real market,” where the price of a shirt changes by the hour and is different by its size and even color. Rivoli's book is full of memorable people and scenes, like the noise, the bad air and the “muddy sweet smell of the cotton,” she says. “Here in the factory, Shanghai smells like shallow water Texas.”

    Rivoli is at her best when making those sorts of unexpected connections. She even finds one between the free traders and those who are against globalization. The chances opened up by trade are vast, she argues, but free markets need the correcting force of politics to keep them in check. True economic progress needs them both.

    The spine (脊柱) stands at the center of your health, providing your body with structure and support. It also contains a major collection of nerves that deliver electric signals from the rest of the body to your brain. So it's important to take care of it.

    Staying in a good position is one of the most important things to keep your spine healthy. A proper position means standing or sitting while keeping your spins straight, except for its natural bending. Positions play a vital part even when you're asleep. Stomach sleeping is far from a good idea. Many people prefer sleeping on their side, which is in the interests of their spine. Sleeping on your back has lots of benefits yet can cause lower back pain and put some pressure on your spine.

    Staying still for too long — even if your position is good — can be hard on your back. Especially if you work at a task most of the day, it's important to get up and stretch (伸展) periodically. Strength exercises with light weights like push-ups can also help by strengthening the muscles. However, don't overdo the exercise, as repeated movements can hurt the muscles around the spine, as trying to lift heavy weights with poor technique.

    Vitamins also affect the health of your spine. In particular, vitamin B and omega-3 fatty acids help keep nerves healthy. Another important part is vitamin D, which is required for strong bones. Vitamin D can come from some foods, but it's also absorbed from sunlight, so it may help to do some exercises outside. At last, many of the actions necessary to keep a spine healthy are similar to those used to protect your health in other ways. So protect your back, and the rest of the body will benefit.
