Article: Britain's Solo Sailor Ellen MacArthur started sailing with her aunt when she was eight. She loved it so much that she saved her money for three years to buy her first small sailing boat.When she was 18,she sailed alone around Britain and won the "Young Sailor of the Year" award. But Ellen really became famous in 2001.Aged only 24,she was one of only two women who entered the Vendee Globe round the world solo race,which lasted 100 days.Despite many problems,she came second in the race out of 24 competitors and she was given a very warm welcome when she returned. Ambition and determination have always been a big part of Ellen's personality.When she was younger,she lived in a kind of hut for three years while she was trying to get sponsorship to compete in a transatlantic race.Then she took a one-way ticket to France,bought a tiny seven-meter Class Mini yacht,slept under it while she was repairing it,and then she raced it 4,000 kilometers across the Atlantic in 1997,alone for 33 days. Ellen has had to learn many things,because sailing single-handed means that she has to be her own captain,electrician,sail maker,engineer,doctor,journalist,cameraman and cook.She also has to be very fit,and because of the dangers of sleeping for long periods of time when she's in the middle of the ocean, she has trained herself to sleep for about 20 minutes at a time. And she needs courage.Once,in the middle of the ocean,she had to climb the mast of a boat to repair the sails at four o'clock in the morning with 100 kph winds blowing around her.It took her many hours to make the repairs.Ellen says,"I was exhausted when I came down.It's hard to describe how it feels to be up there.It's like trying to hold onto a big pole,which for me is just too big to get my arms around,with someone kicking you all the time and trying to shake you off." But in her diary,Ellen also describes moments which make it all worthwhile: "A beautiful sunrise started the day,with black clouds slowly lit by the bright yellow sun.I have a very strong feeling of pleasure,being out here on the ocean and having the chance to live this.I just feel lucky to be here."

question:
Article: Do you like seahorses? What do you know about them? The seahorse is actually not a horse but a fish, and much smaller than any regular horse. In general, a seahorse is about an inch long. It is a beautiful fish that likes warm waters, swims upright , and looks a little like a chess piece. Seahorses are an unusual kind of animal because the males give birth to babies. Mating takes place in cooler waters on spring and summer nights with a full moon. The females put their eggs into the bodies of the males, and the males give birth to baby seahorses. The seahorse can use each eye separately, which allows it to search for food without moving the rest of its body. Seahorses situate themselves near deep, fast-running channels rich in plankton, a kind of life on which they feed. They can catch food from an inch and a half away. Seahorses can change from gray or black to yellow or purple within seconds to fit in with their surroundings, and in this way escape from most of their enemies. One of the surprising facts about seahorses for most people is that they are vertebrates . They can turn and curl freely, and like to swim in pairs connected by their tails. Their tails are powerful, and they can use them to grasp the surrounding seaweed to keep themselves from being swept away. So seahorses are usually found in warm water filled with seaweed. Now that you know all these facts about seahorses, don't you find them more interesting?
