There was once a guy who suffered from cancer, a cancer that can't be cured. One day he was sick of staying home and wanted to go out. He passed a CD store and looked through the front door for a second. He saw a beautiful girl about his age and he knew it was love at first sight. He opened the door and walked in, not looking at anything else but her. He walked closer and closer until he was finally at the front desk where she sat.

    She looked up and asked, “Can I help you?” She smiled and he thought it was the most beautiful smile he had ever seen before. He said, “UH…Yeah…Umm… I would like to buy a CD.” He picked one out and gave her money for it. “Would you like me to pack it for you?” she asked, smiling her cute smile again. He nodded and she went to the back. She came back with the packed CD and gave it to him.

     From then on, he went to that store every day and bought a CD. He took the CD home and put it in his closet. He was still too shy to ask her out. His mother found out about this and encouraged him. So the next day, he took all his courage and left his phone number on the desk before he ran out.

    Several weeks later the phone rang, and the mother picked it up. It was the girl!!! The mother started to cry and said, “You don't know? He passed away yesterday…” Later that day, the mother went into the boy's room and opened the closet. Inside were piles and piles of unopened CDs. She picked one up and opened it. Out fell a piece of paper, saying: “Do you want to go out with me? Love, Jocelyn.” The mother was deeply moved and opened another CD… Again, there was a piece of paper with the same words.

    Darek Fidyka, a 38-year-old Bulgarian, had been paralyzed (瘫痪的) from the chest down for four years after a knife attack. Scientists from Britain and Poland took cells from his nose, transplanted (移植) them into his back and re-grew his spinal cord (脊髓). Now he can walk and even drive a car. The doctors were delighted but said it was the first step in a long journey.

    The breakthrough came after 40 years of research by Professor Geoff Raisman, who found that cells had the possibility to repair damage to nasal (鼻腔的) nerves, the only part of the nervous system that constantly re-grows. “The idea was to take something from an area where the nervous system can repair itself and put it into an area that doesn't repair itself,” Professor Raisman said.

    Polish doctors injected (注射) the nasal cells into Mr Fidyka's spinal cord above the injury and used some nerves from his ankle to form a bridge across the damaged tissue. The nasal cells appear to have caused the spinal nerves to repair themselves.

    Professor Raisman achieved this with rats in the late 1990's, but this is his greatest success. “I think the moment of discovery for me was Christmas in 1997 when I first saw a rat, which couldn't control its hand, put its hand out to me. That was an exciting moment, because I realized then that my belief that the nervous system could be repaired was true.”

    Doctors chose the easiest case for their first attempt—it might not work for others. But there is a real sense of hope that an idea once thought impossible has been realized.

    David Nicholls, who helped provide money for the breakthrough, said information about the breakthrough would be made available to researchers across the globe.

    “What you've got to understand is that for three million paralyzed people in the world today, the world looks a totally brighter place than it did yesterday,” he said.

    London is one of the most popular sites in the world for tourists to visit.If you are planning a trip to London in the future,you're lucky.There are a variety of attractions for you to enjoy.

    One of the most popular tourist attractions in London is the Tower of London.Founded more than 900 years ago, the Tower of London is one of the world's most famous towers and has changed a lot.Here,you can also find the seven ravens（乌鸦）which live in the Tower.There is a story that says: If there are no ravens in the Tower, the Tower and the kingdom will fall.There are also lots of tours,exhibits.and special events that you can enjoy throughout the year.

    Another popular place to visit is Westminster Abbey.It was set up in 1065 by Edward the Confessor.Visitors to Westminster Abbey can enjoy its beautiful special Gothic architecture（哥特式建筑）.There are also lots of memorials of Kings and Queens to enjoy.Excellent transportation is available here by bus or tube from many locations in London.

    Buckingham Palace is another place with a rich history to discover.It's the official London residence（住处）of Queen ElizabethⅡ.During August and September,you can visit the State Rooms and see the Changing of the Guards.The Queen's Gallery is open to the public daily.Checking the official timetable before you make sure to visit the Palace is a must,because it is not open year round.

    Why read, and sometimes even write poetry? That question is not difficult to answer if we change the word poetry to songs.

    I sing when I feel good. When I sing my favorite songs, I feel even better. Sometimes when I am listening to music and to the song words, I feel that it was written for me. A good song always makes me feel something. There are songs that I sing in my head between classes and songs that I want to sing when the school bell rings by the end of the day. They help me get through the day.

    They are like bright and warm colors in the middle of grays and shades. I like songs about love and friendship. The extraordinary thing is that my feelings are more special when I sing my favorite songs in English.

    I also like reading. I used to avoid poetry until an e-friend told me I should recite poems and not look up the meaning of the words. Poetry uses many difficult words and idioms, but the best thing is to just forget about them. In the beginning I felt quite strange. Now I always lock the door. Reading aloud gives you a strange feeling, but when you have some practice and fall into the rhythm, and the sounds of the words, it is really a special experience.

    I started with small poems, but now I think I most like long poems. I have different feelings with different poems. When I have had a bad day at school, I read Keats and forget everything. When I am sad I read Wordsworth by the light of a candle. When the poem is finished, I close the book and my sadness is gone.

    A person can use all five senses while spending time with dolphins. We can see them play in the waves, hear them call, and feel their skin. Dolphins can sense you, too, but not in all the same ways. They have good eyesight, for example, but no sense of smell. Sensory biologists try to understand connections between animal behaviors and the senses. One team of these scientists recently made an unexpected discovery about certain dolphins.

    The researchers found that Guiana dolphins can detect electric fields, an ability that may help them find fish to eat. The secret to this newly found sense, say the scientists, is hidden in the dolphins' snouts (口鼻部).

    "We were really surprised to find this in the dolphin. Nobody had expected it," said Wolf Hanke, who led the new dolphin study.

    Hanke and his team suspected the dolphin's electro－sense might have something to do with small dimples (酒窝) on the animal's snout. "We thought they must have some functions," Hank said. To find out for certain, his team studied two Guiana dolphins.

    The scientists first studied the dimples of a 29－year－old dolphin that had died of natural causes. Under a microscope, the dimples looked familiar: they were similar to the sensors used by other animals to detect electric fields.

    Next, Hanke and his team tested a live dolphin, a 28－year－old named Paco, to see if he could recognize an electric field. They taught Paco to swim close to a device that could create a weak electric field in the water. Then the team taught Paco to swim away from the device if he detected any changes. When the scientists created an electric field, Paco swam away—showing that he knew something had changed. When there was no electric field, Paco stayed there. When Paco's snout was covered in plastic, he didn't react to the electric field.

    Paco's behavior told the scientists that the dolphin used his snout to detect the tiny electric field. "This is a major breakthrough," Peter Madsen, a sensory biologist, said.
