"When is the best time to visit Australia?" many people ask me very often.(尽管) it seems easy, it is hard to answer it, in fact.
It(很可能) depends on(取决于) where you want to go. Someone says the best time to visit Australia (也许) be in October or November, because the (天气) is not very hot or cold at that time. (然而), Australia is quite large from (西北) to southeast and it lies in several climate zones(气候带) .It's about thousands of (英里) from east to west, so you should (认为) about it before you decide where to go.
It also depends on what kind of activities you are (感兴趣的) in. The weather will be more important if you want to go ice (滑冰) or if you hope to go swimming.
In my opinion, any time is a good time to visit Australia.
All week long, it seems you sit inside at school when it is fine outside. But when the weekend comes, it is very cloudy. There is rain according to(根据) the weather report.
Scientists studied more than 40 years of weather data(数据) from around the world. It shows weekend weather is different from weekday weather in some places.
Part of the study involved(包括) 660 weather stations in the US. At more than 230 of these places, the weather on Saturday, Sunday and Monday was different from the weather on Wednesday, Thursday and Friday. The difference was small, but the pattern was striking enough to make the scientists take notice.
"This kind of weekly rise and fall doesn't line up with any natural cycles, "the scientists say. Instead, they think that air pollution from human activities makes the weather become different.
