　　Frogs are animals that can live both in water and on land．There are more than 5,000 kinds of frogs on the earth．The earliest known frogs lived about 190 million years ago and the frogs today still look the same．Here are some fun things that you might not know about frogs．Enjoy!

　　The Biggest and the Smallest Frogs

　　Some frogs can be very big．The biggest kind of frog is the Goliath Frog in West Africa．Its body can be nearly 30cm long, about the size of a large cat．The Gold Frog and the Poison Frog are the smallest frogs in the world．They are less than 1cm long．Though the Poison Frog is very small, it is not weak at all．It is dangerous．Any animal that eats it will die very soon．

　　The Best Jumpers

　　Frogs are very good at jumping．They developed jumping legs so that they would not be eaten by other large animals．Using their big strong legs, more frogs can jump over 20 times their own length．It is like a person jumping over about 30,48．The Australian Rocket Frog can even jump over 2m, which is 50 times its body length(5.5cm)．That might be the reason why frogs are called the best jumpers on the earth．

　　The Cryogenic Animal

　　Some frogs like the Common Wood Frog have a special ability to live in very cold places．When the temperature goes down, they become ice frogs．2/3of their body water freezes．Their hearts stop, and their breathing stops too．You may think they are dead, but in fact they are not．Maybe we humans can learn the way that the frogs do for medical purpose．

　　If you’re into sports, you’ve seen it happen－tennis players jump over the net to shake hands after a hard match; football players exchange jerseys(运动衣)after ninety minutes of knocking each other around; even boxers touch gloves at the beginning of each round．Players in every event, from spelling bees to golf(高尔夫球)，act in this way．It’s all part of sportsmanship(体育精神)，a great tradition in sports and competition．It means playing and being calm all through the match．

　　Everyone feels great when they win．In the last few years, you might see some players celebrate a goal(进球)with a long victory dance or talk big about their ability．However, it’s always hard for people to say in public that they made a bad play．Good sportsmanship is what they really need．It’s the golden rule of sports．

　　Good sportsmanship means that you play by the rules, talk politely to everyone during games and stay cool even when you lose the game．At the school sports meeting, for example, it’s more important for you to know how to work as part of a team and cheer your teammates on．That may help you enjoy more success at your future work．In competition－as in life－you may not always win, but believe me, sportsmanship will help you get through, and there is always the next match．
