People in different countries behave (举止) in different ways. What is polite or “good manners (礼貌)” in one country may not be polite in another. For example，Americans usually greet (打招呼) someone they know by saying，“Hi” “Hello” or “Good morning”.We Chinese，on the other hand，usually greet each other by saying，“How are you?” or sometimes “Have you eaten?”or “Where are you going?” But it is bad manners to greet an American by asking him where he is going or if he has eaten. In Italy (意大利) or in the south of France，a man will greet a woman by kissing (吻) her on the back of her hand or on both cheeks (脸颊).But in China and other Asian (亚洲) countries，kissing on meeting someone is thought to be bad manners.

To take another example，belching (打嗝) during a meal in America is thought very rude (无礼节的) while in parts of China and the Arab (阿拉伯人) world，belching is a way of telling your friend that you are enjoying your meal.

There are also different ways of paying a visit to other’s home，standing in line，introducing (介绍) someone to other people，and giving thanks. For example，if an American brings someone a present，he hopes it will be opened in front of him. But we Chinese don’t usually open the present until he has left.

What are the rules (规则) of good manners then?Well，there are too many rules to be written down here. The most important one would be：When in Rome (罗马)，do as the Romans (罗马人) do.

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, most frogs can jump over 20 times their own length. It is like a person jumping over about 30.48m.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.2/3 of 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.
