      How do you know the weather? We learn it on the radio and TV every day. Different

countries have different kinds of weather. For example, the weather in Australia is different

from that in North China because the seasons in Australia are the opposite. Its summer is

from December to February. But in North China it's winter at this time. And in Australia

winter is in June, July and August. So when it's spring in North China, it's autumn in Australia.

When you visit the country, you'd better choose (选择) the best time.
