Australia is the greatest island in the world. It is to the south of the equator. So when it is summer in our country, it is cold winter in Australia.

Australia is big, but the population（人口）there is thin. The population is the same as that of Shanghai, a city of China. Australia is young and diverse nation and Australian people come from many different countries.

    Australia has many, many sheep. After a short drive from town, you will see sheep around you. You can also find kangaroo has a “bag” below its chest. The mother kangaroo keeps its baby in the “bag”.

Australia is considered to be a relaxed, informal society（社会）. When greeting others, students and young people say “Hello” or “Hi”. Sometimes they will say “How's it going?” or “G day”. In more formal（正式的）situations they usually shake hands the first time they meet. “Good morning”, “Good afternoon” or “Pleased to meet you” are formal greetings. English is Australia's national language.

    Tea is an important part of Chinese tradition. Tea has very close relationship to Chinese culture.

    It is said that Chinese tea was discovered by King Shen Nong. People say that he lived 5，000 years ago. One summer day, while he was visiting a faraway part of his country, he felt very thirsty. The servants began to make water hot enough for him to drink. Dried leaves from a near plant fell into the water. The king drank some, and found it could make him feel less tired. Also as a scientist, Shen Nong was interested in the new drink. And so, tea was created in 2737 BC.

    Drinking tea has many advantages. It makes people feel less tired, clears heat inside the human body and helps people become slimmer. As you add a cup of tea to your daily life, please check the following helpful advice.

    Drink it hot. Tea oxidizes(氧化)quickly, so it is suggested that you drink it hot.

    Do not drink too much strong tea. It will probably be harmful to your stomach and make you feel sick if you make the tea too strong.

    The best time to drink tea is between meals. It may not make you have a strong wish to eat when your stomach is empty, or cause stomachache when your stomach is full.

    Do not drink with medicine. It may change the medical result. You can drink tea two hours after you take medicine.

    Green tea is the best choice for office workers. Why? Because green tea helps stop the bad result of the computer.

    Red, green, blue, black and white are basic(基本的) colours.

    The world is colourful(多彩的). The sea is blue. The grass is green. Most countries in the world like green because it's a symbol(象征) of life(生命)，but people from England and Japan don't like it. Red is a popular(流行的) colour in China, but in Thailand(泰国)，it is bad to write names in red ink(墨水). It means someone is dead(死亡的).
