Sound travels very well through water-much better, in fact, than it does through air. So it shouldn't be surprising that many ocean animals make noise. They use sound to communicate and hunt. As biologist Brandon Southall says, “Their whole world is related to sound.”

    Dolphins whistle, organizing hunts. Lovesick whales sing so loudly they can be heard hundreds of miles away. But these days they aren't the only ones sounding off. They have more and more competition from human machines.

    Every day, thousands of huge container ships sail across the world's oceans. On top of the engine noise, the ships' propeller (螺旋桨) make a loud noise all the time. All that can make it hard for ocean animals trying to listen out for friends, or dinner. Animals swimming nearby a ship can be deafened or even killed.

    Underwater construction can also be dangerously loud. When construction machines called pile drivers were used during repairs to the San Francisco-Oakland Bay Bridge, dead fish appeared.

    Geologist (地质学家) pound on the seafloor too, trying to find oil wells and map Earth's surface. The results are useful lo science, but all that hammering probably gives ocean animal a headache.

    As people realize how important sound is to ocean animals, they are looking for ways to reduce human noise. Ships could get quieter just by slowing down. Engineers are also trying to find quieter propeller ships.

    Now some companies are using a simple invention called a bubble curtain, which makes sound waves passing through it lose energy and gel quieter. It seems to work - when bubble curtains were fixed on the San Francisco bridge project fish deaths dropped.

    We still have a lot to learn about sound in the oceans, but together we can help keep the sea a quieter place.

    Two of the saddest words in the English language are if only. I live my life with the goal of never having to say those words, because they convey regret, lost opportunities, mistakes, and disappointment.

    My father is famous in our family for saying, “Take the extra minute to do it right.” I always try to live by the “extra minute” rule. When my children were young and likely to cause accidents, I always thought about what I could do to avoid an “if only” moment, whether it was something minor like moving a cup full of hot coffee away from the edge of a counter, or something that required a little more work such as taping padding (衬垫) onto the sharp corners of a glass coffee table.

    I don't only avoid those “if only” moments when it comes to safety. It's equally important to avoid “if only” in our personal relationships. We all know people who lost a loved one and regretted that they had foregone an opportunity to say “I love you” or “I forgive you.” When my father announced he was going to the eye doctor across from my office on Good Friday, I told him that it was a holiday for my company and I wouldn't be here. But then I thought about the fact that he's 84 years old and I realized that I shouldn't give up an opportunity to see him. I called him and told him I had decided to go to work on my day off after all.

    I know there will still be occasions when I have to say if only about something, but my life is definitely better because of my policy of doing everything possible to avoid that eventuality. And even though it takes an extra minute to do something right, or it occasionally takes an hour or two in my busy schedule to make a personal connection, I know that I'm doing the right thing. I'm buying myself peace of mind and that's the best kind of insurance for my emotional well-being.

    A young Los Angeles actor in need of a second job to pay his bills has come up with a brilliant way to supplement his income-people walking.

    Chuck McCarthy originally considered becoming a dog walker to earn some extra cash, but soon realized that the job required more than walking dogs on a leash. However, walking people didn't require much when they were out on walks. Chuck realized there was money to be made if he walked people around Los Angeles instead.

    It might sound like a joke, but The People Walker, as he calls himself, is very serious about his new job. For $7 per mile, he offers to walk with clients around L.A., listening to their problems or simply making conversations and offering them a sense of security. At 6-feet, 2-inches, and sporting a bulky figure and bushy beard, Chuck doesn't look like the kind of guy you'd want to mess with.

    Chuck's services are aimed at people who need a motivational boost to go walking, those who don't feel safe walking alone in some areas, and those who are afraid that people might see them walking by themselves and think that they have no friends. “I wear my The People Walker shirt upon request and on the first walk with a new client, so they can be 100% sure it's me,” McCarthy says. However, he admits some people are a bit uncomfortable with this policy, as they don't necessarily want everyone to know that they're being walked.

    So far, Chuck McCarthy has already had another five people walkers employed, covering various areas, like downtown L.A., Hollywood, Eagle Rock, or Fairfax. Once he posted signs around the city, his phone started ringing and clients began rolling in. And with all the free publicity he has been getting in the press lately, more requests are coming.

    While he hopes that his acting career will pick up soon, in the meantime Chuck is very happy with his people walking business. After all, it's literally a walk in the park and it pays the bills.

    Kompong Phhluk Private Tour

    Depart the city for an unspoiled floating community called Kompong Phhluk which is well-known for its stilted-house (吊脚楼) villages and flooded forest.

    After this market tour we'll all have a boat trip to the floating community of Kompong Phhluk, visit an island pagoda, school and houses standing on 8 or 10m high stilts, fish farms and learn about the village life.

    Stop and have lunch in a family's house before getting into a row boat and venturing into the flooded forest, the habitat to some famous water-bird species.

    Eventually we jump back into the big boat and set off for the largest fresh water lake in SE Asia, Tonle Sap.

    In China, chain restaurants especially the big multinational ones are cool. Going to Starbucks, for example, is a status symbol. It not only says, "I'm rich enough to buy this overpriced coffee, "but also, "I'm cosmopolitan (见多识广的) enough to be part of globalization."

    Where I come from in the UK, however, chains are neither fashionable nor gourmet (美食的). Chains are where you go on New Year's Day when nowhere else is open, or when you are 5 years old and your parents can't stand hearing, "I'm hungry!" any longer. In my own case (with regards to McDonald's), a chain is where you are taken on your first "date". Even at the age of 13, I knew to give the guy the "let's just be friends" phone call the next day.

    In the UK, independent cafes and restaurants are making a comeback on the fashion scene. Nowadays, a Londoner who says "let's meet for a coffee at Monmouth" (an independent café) is much cooler than one who says "let's go to Starbucks". Even if Monmouth's coffee is a little more expensive, there's a satisfaction in knowing your pounds aren't going straight to the big corporations.

    Of course, there are chain stores all over the UK; you can't go five minutes without spotting a Costa Coffee. But numbers do not add up to good taste.

    I do, however, have a confession (坦白). After moving to China I had moments when all the rice and Kung Pao Chicken became too much. I, too, have retreated to McDonald's.

    Dr. John Wilkins was a natural philosopher who lived from 1614 until 1672. He was crazy about getting to the moon and meeting the people who surely lived there. Wilkins believed that anything as Earth-like as the moon must have been created by God for living beings, and he was determined to meet them — despite the fact that he was three centuries ahead of his time.

    In the 1600s, the scientific understanding of gravity and outer space was limited. Wilkins believed, like many 17th-century scientists, that there was no difference between the atmosphere of Earth and the conditions in space, and that Earth's pull was due to magnetism (磁力). It was only reasonable, then, that Wilkins believed a two-wheeled horse-drawn battle car with wings with enough speed could lift high enough off the ground to break free of Earth's magnetic pull and reach the moon.

    Then Wilkins moved on to more pressing issues with his remarkable ability to think of new ideas: How would travelers feed themselves during the journey? He theorized that the main cause of hunger was simply the act of working against gravity, so getting to the moon without being burdened by it would be able to be realized. There was some knowledge at that time about the fact that air gets thinner and colder the higher up you go, but he had a fix for that too, "moistened sponges (湿润的海绵) might help us against its thinness".

    By studying the way in which birds fly, which also happened to be part of the studies that led to planes and rockets centuries later, Wilkins put his theory to the test with the help of a colleague, Robert Hooke. Neither of the two ever recorded their attempts, but it's somewhat safe to say that it didn't work out. Hooke himself may have been the reason he gave up hope, in fact, since he was part of the team that discovered space was a place without oxygen.
