① Many people go to Australia for vacation. People often ask what the weather is like in Australia. The answer is that it changes a lot! Why? Because Australia is a large country. The weather in different parts of the country is different.
② The northern parts of Australia are warm or even hot all year round because they are close to the equator(赤道). In the north, summer is also the rainy season.
③ The areas along the coast(海岸) around Sydney are warm in winter with the temperatures of about $10° \mathrm{C}$ to $16° \mathrm{C}$. Summer there is warmer and the temperature is about $26° \mathrm{C}$.
④ However, if you think all parts of the country are warm all year round, you'll be mistaken. Some parts in Australia are very cold during the winter. When we say "cold", we don't mean the cold like the winter in Harbin. In some places in Tasmania and Victoria, you can see snow and temperatures there are below zero. In fact, many people do not know that there are ski resorts(滑雪胜地) in the mountains of Australia.
⑤ Anyway, Australia is a good place to visit. English is its national language. You can enjoy everything here from sunbathing at the seaside to brushing snow off your shoes after a day of skiing. If you want to go there for a visit, all you should think about is the weather there.
