In Barnes London Wetland Centre, you can enjoy a large number of wild birds and wild animals. Adults' fare is ￡7.95, and children's fare is ￡4.50. But if holding a London pass, you can have free admission(入场)。

London Wetland Centre is thought to be the European City's best place to contact wild animals. London Wetland Centre is the UK's most worthy of showing off, and the most exciting wildlife projects, including(包括) 43 hectares of grassland, as well as pools.

Barnes wetlands are located in the Thames. This award-winning centre always interest many scientists. There are many different kinds of animals, including the cormorant(鸬鹚), the kingfisher(翠鸟) and the endangered water vole(河鼠).

In London Wetland Centre there are a large number of different habitats. When visiting the centre, visitors can watch movies through the video to learn more about wetlands and the knowledge of biological species(物种).

      For children, London Wetland Centre is a good choice to learn a lot about the knowledge of nature.

      There are many other interesting places about wildlife. If you are interested in wildlife, Why not go to London Zoo, Regent Park or River Thames downstream to experience the world's most beautiful gardens? Holders of London Passes can visit them freely.

    There are some very good inventions which， for one reason or another， don't become popular. These inventions should be better known， even though I think that some of them are crazy. Let's have a look at some of these inventions and see if you agree that they should be more successful.

    The Australians had a great idea to stop people from drinking and driving. The idea was that if a driver wanted to start the car， she or he would have to blow into a bag first. If there was too much alcohol(酒精) in their breath， the car wouldn't start. It sounded like a great idea to me， but people said that they might need to drive the car in an emergency even if they had drunk too much alcohol. Another idea I liked was an invention by a scientist who thought his children watched too much TV. He linked the TV to an exercise bike so that the electricity to power the TV was generated(产出) by the bike. If the children wanted to watch a lot of TV， they had to pedal(踩踏板) very hard. I found another invention on the Internet which was intended (倾向于) to encourage good habits. Believe it or not， this invention was an ashtray(烟灰缸) which spoke to you when you lit a cigarette! The “voice” of the ashtray was activated (启动) by the heat from the cigarette and reminded you how dangerous it is to smoke.

    One of the strangest inventions I have come across is a bicycle which can cross rivers! The idea was that when you came to a river， you could inflate a huge plastic ball all around the bike. You would then get into the ball which would float on the river while you pedaled the bike inside the ball! Why not use a bridge instead? A friend of mine at school once bought a strange pair of football shoes. On the bottom of the shoes there was a rotating pad of studs (转动钉垫). The idea was that you would change direction more quickly if the studs rotated with you. The problem was that every time you stopped you changed direction whether you wanted to or not! I think he wore those shoes twice! One thing I would like is a baseball cap with a built-in radio so you can listen to sport all day with your hands free. While we are on the subject of sport， the Americans invented a kind of robot for sports fans. If you were watching your team on TV on your own， you could press a button and the robot would do “high fives” with you! Fantastic! I wonder if you have any good ideas for inventions like these.

    Baboons(狒狒) live in Africa. They are like monkeys. Most people think daddy baboons don't know their babies. But scientists (科学家) find that daddy baboons know how to help their babies. The daddy baboons are smart.

    Joan Silk is a scientist. She studies the baboons for 3 years. She says the daddy baboons are happy to see their babies. They have big teeth to help the babies to eat hard things. Mother baboons are small. And they live in a place. When a mother baboon gives birth(分娩), she often has only one baby. Baby baboons have fur. They are very cute.

    During the day they eat things. At night, they sleep in the trees. Most children like baboons because they look like the man.

    There are some easy things you can do to protect(保护) the environment and the earth. Choose ideas from the list or come up with a few of your own.

    ●Plant flowers grass or trees.

●Whenever you visit a park or beach, take away what you bring there—-keep rubbish in a bag until you can put it in a dustbin.

    ●Turn off the lights, TV sets when you leave the room. This saves a lot of electricity.

    ●Turn off the tap when you brush your teeth. You can save some water by not letting it run. Also, use a glass cup instead of a paper cup because this saves paper.

    ●Keep the doors and windows closed in winter to keep warm air in.

    ●Give your old books and magazines to a library instead of throwing them away.

    ●Give your old clothes to poor children you know instead of throwing them away.

    ●Use both sides of paper.

    ●Stop pouring dirty water into the rivers or the lakes nearby.

    ●Encourage all your friends to do the same things you do to help protect the earth.

    You don't have to wait until Earth Day to do these things. Make every day Earth Day.

    If everyone makes a contribution (贡献)to protecting the environment, the world will become much more beautiful.

    Many scientists believe our love of sugar may actually be an addiction (上瘾). When we eat or drink sugary foods, the sugar enters our blood and influences parts of our brain that make us feel good. Then the good feeling goes away, leaving us wanting more. All tasty foods do this, but sugar has a particularly strong effect. In this way, it is in fact addictive, and doctors suggest we all cut down on it.

    "It seems like every time I study an illness, I find my way back to sugar," says scientist Richard Johnson. One-third of adults worldwide have high blood pressure (血压), and up to 347 million have diabetes (糖尿病). Why? "Sugar, we believe, is one of the reasons, if not the main reason," says Johnson.

    Our bodies are designed to survive on very little sugar. Early humans often had very little food, so our bodies learned to keep sugar as fat. In this way, we had energy stored for when there was no food. But today, most people have more than enough. So the very thing that once saved us may now be killing us.

    So what is the solution? It's obvious that we need to eat less sugar. The trouble is, in today's world, it's extremely difficult to avoid. From breakfast cereals to after-dinner desserts, our foods are increasingly filled with it. Some manufacturers (制造商) even use sugar to replace taste in foods that are advertised as low in fat. This may make the food appear as healthier, but large amounts of sugar are often added.

    But there are those who are fighting back against sugar. Many schools are offering more fruit instead of deserts. Other schools are building facilities for students to do exercise. The battle has not yet been lost.

    Which is the tallest mountain on the earth? The answer must come fast—MT Everest, at a height of 29,000 feet.

    But that is only on land. For, if you were to measure (测量) from the bottom (底部) of the ocean. The tallest mountain in the world will probably be Mauna Kea in Hawaii. It is more than 15,748 feet under the sea and another 13.779 feet above it.

    As US scientist Cindy Lee Dover points out that the seafloor is the largest and least known place on the earth. We know more about Mars (火星) and Venus (金星) and the back side of the moon than we know about the seafloor.

    Some people have travelled to the deep water of the ocean to try to find all kinds of unknown animals and plants living in the deep water. Even scientists know very little about them. Many of them perhaps do not even have names. Some of the names given by scientists to newly discovered (被发现) animals are really funny. Among them are the spaghetti worms (意大利面蠕虫), named as such it is found in a tangle (缠结), it is often difficult to make out where one ends and another begins! Just like spaghetti.
