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.

    In most parts of the world, many students help their schools make less pollution. They join environment clubs. In an environment club, people work together to make our environment clean.

    Here are some things students often do.

    No-garbage lunches. How many lunch bags do you throw away after lunch? Environment clubs ask students to bring their lunches in bags that can be used again. Every week they will choose the classes that make the least garbage and report them to the whole school.

    No-car day. On a no-car day, nobody comes to school in a car including the students and the teachers. Cars give pollution to us, so remember：

    Walk, jump, bike, or run!

    Use your legs! It's lots of fun!

    Turn off the water! Do you know that some toilets can waste twenty to forty cubic meters of water an hour? In a year, that would fill in a small river. In the environment clubs, students mend those broken toilets.

    We love our environment. Let's work together to make it better.

    What is the most stressful (有压力的) thing in school? It is probably exams. Exams can put us under a lot of stress. But some students do better under stress, while others do not. So, why do some students behave better under stress?

    It all comes down to dopamine (多巴胺). Dopamine is a chemical in our body that sends signals in the brain. It has many important roles: influencing memory, attention and how we learn.

    Our brains work best when there is a balance (平衡) of dopamine—not too much or too little. Our brains control dopamine in two ways. It either takes out dopamine quickly, or bit by bit. Exam success can be connected to how fast dopamine goes back to a balance, according to new research from the University of Missouri, reported Yahoo.

    What happens when we take an exam? If you become stressed, your brain will start to overload on dopamine. It is like a cup overflowing with water. The quicker you are able to go back to a balance of dopamine, the quicker you can focus, helping you do better on a test.

    Scientists found that, during a test, people who slowly got back to a balance of dopamine scored 8 percent lower. That's the difference between a good mark and a bad mark.

    But don't fear, there is good news for every student. The study also found that the more practice you get, the less stressed you will be. So, it turns out that     .

    What should you do if there's an earthquake at school? How can you protect yourself when you are caught in a stampede(踩踏)?March 28, 2016 provided you with a good chance to learn about safety.

    This day was called the National Day of Education on the Safety of Elementary and Middle School Students(NDESEMSS)(全国中小学生安全教育日). The theme of the day was to give students more knowledge about safety and make sure their lives are safe.

    A survey done by the China Youth and Children Research Center showed that school accidents kill more elementary and middle school students than anything else. The main accidents come from stampedes, earthquakes, fires and sports injuries(伤害).

    What can we do to keep ourselves safe? Staying calm is the first and most important rule when facing accidents. But different accidents have different self-protection advice.

    A stampede is possible anywhere. The larger a crowd gets, the more likely stampedes become. When students around you begin to push, stand still and try to hold onto something, or stay in a corner until the crowd leaves. If you fall down in a moving crowd, cover your head with both hands. Lean to(偏向) one side, curl up(蜷缩) your body and bend your legs.

    Earthquakes are common natural disasters(灾难). When you feel the ground shake, drop down, take cover under a desk and hold on. You should stay indoors until the shaking stops. If you are outdoors, don't stay near buildings, trees or power lines.

    When there's a fire, follow the teachers' instructions, leave the classroom quickly and use a piece of wet cloth to cover your mouth and nose so that you don't breathe in smoke.
