Along the river banks of the Amazon and the Orinoco there lives a bird that swims before it can fly, flies like a fat chicken, eats green leaves, has the stomach of a cow and has claws(爪)on its wings when young .They build their homes about 4.6m above the river ,an important feature(特征)for the safety of the young. It is called the hoatzin.

    In appearance, the birds of both sexes look very much alike with brown on the back and cream and red on the underside .The head is small, with a large set of feathers on the top, bright red eyes, and blue skin. Its nearest relatives are the common birds, cuckoos. Its most striking feature, though, is only found in the young.

    Baby hoatzins have a claw on the leading edge of each wing and another at the end of each wing tip .Using these four claws ,together with the beak(喙),they can climb about in the bushes, looking very much like primitive birds must have done. When the young hoatzins have learned to fly, they lose their claws.

    During the drier months between December and March hoatzins fly about the forest in groups of 20 to 30 birds, but in April, when the rainy season begins, they collect together in smaller living units of two to seven birds for producing purposes.

    London has become a cycle-friendly zone after the launch of a new bike hire scheme.{#blank#}1{#/blank#}

   {#blank#}2{#/blank#}First you have to sign up to the scheme to be sent a key. The key will unlock one of the bikes, which are kept at docking stations in and around central London. You have to pay an access fee for the key and then you pay as you go, for the length of time you use the bike.

    Transport for London, which runs the scheme, are hoping to have 6,000 bikes and 400 docking stations in place by the end of the year. {#blank#}3{#/blank#}London Mayor Boris Johnston launched the scheme and said London has been “filled with thousands of gleaming (发光的) machines that will transform the look and feel of our street and become as commonplace on our roads as black cabs and red buses”.

{#blank#}4{#/blank#} On the first day some people found they couldn't dock their bike properly and their usage of the bike had not registered. Transport for London did admit they had been expecting a few “teething problems” and have said they would not charge for the first day as a “gesture of goodwill”. Some other people have criticized the lack of docking stations and locks for the bikes as well as the price it costs to hire the bicycles.

    Chinese students' extremely neat handwritten compositions have aroused a heated debate among Internet users since photos of the compositions and a teacher's picky remarks were published on Daily Mail Online.

    “Can you believe this essay is handwritten? ” Daily Mail Online asked.

    The website reported on the compositions that looked like they had been machine printed and on the teacher's remarks at Hengshui High School in North China's Hebei Province, one of China's top 100 high schools. The teacher wrote, “not one stroke (笔画) more, not one stroke less” about some compositions that weren't neatly written.

    The story immediately aroused a heated debate among British Internet users and got 652 comments after it was published on Wednesday. Some British readers were amazed by the neat handwriting and attributed (归于)China's growing development to this strict teaching method. A reader named Jim said, “This is another example of why China is rising to the top”, and his comment gained 72 supports. But some readers thought the too-picky method doesn't make sense in helping students learn better English and suppresses（压制） students' creativity.

    Chinese Internet users also expressed different opinions after English newspapers, a user of China's Twitter like Sina Weibo, posted the story along with its comments on Weibo on Thursday. Since then, the post has received 1, 479 comments. Sina Weibo user wenjinzetui said, “Beautiful handwriting proves an ability”, echoing an old Chinese saying that the style is the man. However, another Weibo user, honorificabilitus, said, “It's meaningless to pursue that neat English handwriting, since learning language is for communicating, let alone English students don't write that neatly. ”

    There are also many Weibo users showing worry about this too-strict teaching method, as weibo user li-owl-stop said, “We should reflect the Chinese-style education, and it's hard to imagine what would happen if all the schools in China adopted the teaching method at Hengshui High School. ”

    Fabien Cousteau was born with deep love for the ocean. His grandfather and his father were ocean explorers and documentary filmmakers. Fabien spent his early years on his grandfather's ships. Today Fabien follows in his family's footsteps to protect the planet's endangered ocean life. With his vast knowledge and experience, he tries to strike a balance between environmental problems and market economies.

    Fabien is well known for his study of sharks. During 2000-2002, he created a TV special called Attack of the Mystery Shark based on the shark attacks that occurred along the New Jersey shoreline in the summer of 1916. Then in 2003-2006, with the help of a large crew, Fabien created a shark submarine (潜艇) that enabled him to put himself inside the shark world, providing people with a rare view of the mysterious and often misunderstood creatures.

    For the next four years (2006-2010), Fabien was part of a series called, Ocean Adventures, which offered a rare look into some of the most fantastic ocean species (物种) and environments.

    In 2010, Fabien started Plant A Fish, a nonprofit project for children to help restore local water ecosystems by replanting key ocean species. Save the world, one fish at a time. The project is still in progress now and its final goal is to plant 1 billion "fish" worldwide.

    From June 1 to July 2, 2014, Fabien and his team spent 31 days underwater to research how climate change and pollution are affecting the oceans. Fabien's Mission 31 broke new ground by going deeper, longer and further, exposing (显露) the world to the adventure and the mystique (神秘) of what lies beneath.

    Fabien is currently working on a documentary film about the adventures of Mission 31, as well as building an Ocean Learning Center to provide children around the world with the opportunity to learn about oceans and engage with ocean explorers directly through social media.

    A Christmas Carol was written by Charles Dickens. The first 6,000 copies of the book were sold out in a week. And the book has inspired many plays and movies. The first play was put on in 1844. The first two movies were silent films made in 1901 and 1908. Since then, the story has been remade more than 60 times for television and cinema. What makes such a tale so attractive? Audiences have always loved a good plot, a villain(反面人物)who harms other people or breaks the law, and the ending of right over wrong. The book offers all three.

    The book tells the story of a man named Ebenezer Scrooge. He is mean and cruel(残忍的)to his clerk and turns away his only living relative. One night, Scrooge is visited by three spirits. The first shows scenes from Scrooge's youth that led to this present state. The second takes him to the homes of his clerk and his nephew. Here Scrooge sees that people can be happy without lots of money. The spirit also shows him the desperate poor people of London. The third spirit shows Scrooge will die alone, and no one will care if he continues to live as he has. At last the message is understood, and Scrooge repents. He becomes generous and caring to all around him, especially to his clerk's sick son, Tiny Tim.

    Every year, thousands of people watch A Christmas Carol. Why? They may be touched by its lessons on the true meanings of wealth and happiness. They may enjoy the special effects and feelings or watching every year may be just a habit. Viewers never seem to grow tired of the old miser(守财奴), Scrooge, and his dramatic message of hope and change.
