Probably no other musical instrument is as popular as the guitar around the world. Musicians use the guitar for almost all kinds of music. Country and western music would not be the same without a guitar. The traditional Spanish folk music called Flamenco could not exist without a guitar. The sound of American blues music would not be the same without the sad cry of the guitar. And rock and roll music would almost be impossible without this instrument.

    Music experts do not agree about where the guitar was first played. Most agree it is ancient. Some experts say an instrument very much like a guitar was played in Egypt more than 1,000 years ago. Most experts say that the ancestor of the modern guitar was brought to Spain from Persia sometime in the 12^th century. The guitar continued to develop in Spain. In the 1700s it became similar to the instrument we know today.

    Many famous musicians played the instrument. The famous Italian violins Niccole Paganism played and wrote music for the guitar in the early 1800s. Franz Schubert used the guitar to write some of his famous works. In modern times Spanish guitarist Andres Segovia helped make the instrument extremely popular.

    In the 1930s, Les Paul began experimenting to make an electric guitar. He invented the solid-bodied electric guitar in 1946. The Gibson Guitar Company began producing its famous Les Paul Guitar in 1952. It became a powerful influence on popular music. The instrument has the same shape and the same six strings (弦) as the traditional guitar, but it sounds very different. Les Paul produced a series of extremely popular recordings that introduced the public to this music. Listen to this Les Paul recording. It was the fifth most popular song in the United States in 1952. It is called “Meet Mister Callaghan.”

    It's comforting to think if you were somehow swallowed by a whale, you'd simply hang out in his stomach until he eventually spat you out, unharmed and whole. Unfortunately, your chance of ending up in this type of situation is pretty low.

    In 2012 reporter Ben Shattuck read the records at the New Bedford Whaling Museum Research Library. Despite his extensive research at one of the most comprehensive whaling archives(档案), he failed to find a single report of anyone ever being swallowed alive by a whale. He found plenty of reports of whalers who were bitten or injured by the creatures, and several who died after fighting with a whale, but none related to swallowing.

    With whales' large mouths, it certainly seems possible that a whale could swallow someone whole, so why is it so unlikely? Baleen whales, or whales without teeth, are some of the largest creatures on the planet. Despite their massive size, baleen whales could never get you into their bellies thanks to their relatively small esophagus(食道). These whales are designed to eat small sea creatures, and the opening in their throat is only about as large as a basketball, so you'd never make it that far.

    But what about toothed whales? Sperm whales eat whole seals, so you could easily fit down their throats and into their stomachs. However, once you reached the first of the sperm whale's four stomachs, your journey would probably end quickly. Not only would the whale's stomach acid make quick work of you, but you'd experience a distinct lack of air on the inside. Actually, you're more likely to get eaten or injured as you try to make it past the sperm whale's sharp teeth. Plenty of whalers, have fought with sperm whales and lost their hands or lives due to these mean teeth.

    I always wondered how people would react if I tried to approach a total stranger for help in a busy place like a street corner or in a noisy mall. I have always hurried past a stranger who tried to catch my attention in a busy place or when I am rushing around.

    Yesterday, I was in a busy shopping mall buying a large piece of luggage because I just had the time to do it after many days of planning. After the purchase in one of the large shops, I picked up my phone from my pocket to call my driver waiting in the parking lot but my phone was dead.

    I then requested the shop assistant who had just sold me the luggage to ring the number of my driver for me and she replied that it was the shop policy that they cannot use mobile phones while working in the shop.

    I got out of the shop onto the busy street in front and approached a young mother with her two kids to make a request. As soon as I said “Excuse me, madam”, she grabbed both her kids and ran. I felt like a kidnapper.

    I stood there, wondering how many times I had reacted to strangers like the young mum. I stood there in the busy street with people rushing by, looking at their faces to see if there was a sign of kindness on their faces.

    I saw a man pretty shabbily dressed. He seemed to have noticed me and I just stopped him expecting him to rush past. My request escaped the lips. He immediately called the number of my driver and waited till my car came to be sure I was picked up, and he turned around before I could thank him adequately and was gone. I was surprised by his kindness and hope I will do likewise to strangers who try to catch my attention from now on.

    These days, North Kickapoo Street in Shawnee, Oklahoma, is a four-lane road leading out to the highway, and lined with all kinds of places to eat and shop. But in the mid-1950s, it was just a gravel(砂砾) country road, the perfect place for our daddies to teach us how to drive.

We didn't have driver's education at Shawnee High School. We were on our own. Mom took me to pick up an instruction handbook. I was the oldest of my friends, so we were excited at the prospect of a whole new world opening up. We'd have freedom to get around. Best of all, we could go to the Starlite Drive—In theater on 50-cents-a-carload night. We'd have it made.

    Mom let me back our 1949 Ford out of the garage a few times to get used to the clutch (离合器) and gearshift (变速排挡杆). I got familiar with the motion but was hardly ready for my road test.

    Finally, the day came for Daddy to give me a real lesson. He drove out to the end of the paved section of Kickapoo Street and across to where the gravel started. My daddy had come from a family of 10, and they had been farmers in a poor area in Oklahoma. There was only one way to do things, and that was the right way.

Praises were rare, so when he expressed his approval it was special. I didn't want to experience his glare if I ground the clutch or the car shook as I tried to get it going.

    I took a deep breath, slowly let out the clutch, pushed the stick into second gear, eased down the road, and then carefully moved into third gear. He had me stop and repeat the procedure two or three more times until I came to the end of the section. I was feeling pretty good as I came to a stop and looked to Daddy for approval.

He glared at me and then barked, “You've been driving, haven't you?” He must have thought I'd been practicing in somebody else's car. I quickly explained that my training was all done on the Ford.

    That was 60 years ago. I can still see the nod he gave me when he said, "Well, you did a good job."

    The phone ID flashed，“Emergency Vet”.“ Oh no” I whispered. I could not lose Merlin now.

    Ron and I had tried to have children for a long time with depressing results. I threw myself into my work. Any maternal feelings I had were spent on Merlin.

    I couldn't wait to get home from work each night. I wanted to pick up that warm bundle of loving fur and nestle him. I wanted to sing “Rock-a-bye Merlin”，as I did every night as he would put his paws around my neck.

    Merlin was my comfort especially at times when I wondered if God was listening. But last night something had changed. Not only did I sing “Rock-a-Bye M1erlin”,but I asked, you 're gone？”

    Although Merlin was 19 years old, a senior in the· age of a cat, he didn't look or act that way. I didn't want to accept the fact that he was nearing the end of his lifetime. My job at the law firm was so demanding and stressful that I couldn't imagine getting through the day without Merlin waiting to greet me at home.

    I dialed the vet's number. I asked for my husband but he already left. Then I took a breath and asked the question that no one wants to ask，“Is my Merlin still alive？”The nurse said“ yes.”

    Ron came home and said that Merlin had almost no red blood cells left. White blood cells were replacing them. Merlin would need expensive transfusions most likely on a monthly basis. We both knew Merlin was running out of time. I asked Ron to drive me to the vet so I could say goodbye to my little boy cat but he was beat tired and it was late. Ron said if Merlin was still alive he next morning then he would take me to the vet.

    The next morning I called the vet. Merlin had survived the night. After driving to the vet, I went into the examining room. The nurse brought Merlin and placed him on an examining table on his side. His eyes were tightly shut. I thought he died already. I carefully edged my hand to reach his body. His body felt warm, but when I spoke his name there was no response. No response to his name or that I was there and that I loved him. I was extremely sad. In that examining room I felt helpless. I wondered how many people in an examining room felt as helpless as I did. Feeling driven to prayer I yelled, “God this isn't good enough. I need to see my Merlin the way I remember him, I need a miracle and I need it now！”

    At that moment, God granted a miracle. Merlin's favorite compliment entered my mind. I said, “Merlin, you are beautiful and you are gorgeous, do you hear me？”

One eye opened.

    I said “Gotcha”. I kept repeating those words.

    Merlin opened the other eye and, one limb at a time, got up. He was waiting for that phrase. He wanted to hear that he was beautiful and gorgeous again.

    Then I experienced another miracle.

    There was no sound in that examining room until Merlin started walking to me. From out of nowhere, or maybe from heaven, I clearly heard a song we sung in church often: “It Is Well With My Soul.” I remember叫thinking，“Yes, it is well with my soul. I got to see my little boy cat one more time.”

    Merlin walked to me. He put his face in mine, which he had never done before. He rubbed a circle around my face twice. Merlin said goodbye with his face and marked me for life.

    Ron appeared shocked that Merlin was up and had walked to me. I said to Merlin，“Tell God you are a good boy and how much we love you”and then handed him back to the nurse.

    Tears of gratitude poured forth in memory of a miracle. You see for nineteen years God spoke to me through a special cat named granted a miracle. That miracle gave me time to say goodbye.

    Some years ago, Michel-Andre found himself staring at the body of a dead whale on a beach in the Canary Islands. It was obvious that the animal had been struck violently by a ship——but why? Only later, after surveying the whales which lived in the area and measuring the increase of sound pollution from ships did it become clear that there was a link.

    The whales had become desensitised to the noise of approaching boats and were being struck by them, often seriously. "We never thought that this could be something that could kill," recalls (回忆) Andre, who is the director of the Laboratory of Applied Bioacoustics at the Technical University of Catalonia, Barcelona.

    Andre has spent 20 years developing an advanced system to better understand why incidents like this happen. His underwater microphones have exposed a world of deafening sound and animal communication never observed with such clarity(清晰) before.

    It was not an easy task. Sound waves don't travel through water in the uniform, predictable way they do through the air. Instead, the temperature, salinity (盐度) and, flow of water have great effects on their path.

    What can be done? One solution is to change shipping routes to courses where ships are statistically less likely to meet animals. It's also possible to slow ships down to 18km/h or less, which is less likely to seriously injure a whale.

    As for dealing with the root cause of the problem, the UN's International Maritime Organisation has already published guidelines on how to quieten ships, but it will be a while before the effects of such changes might be observed.

    "The ocean is not our world," comments Andre. But it is ours to look after. And thanks to his work, we can better understand the effects of subsea sound pollution.
