     In England people can experience (经历) four seasons in one day. So they often talk about the weather.

In the morning the weather is warm like in spring. After an hour, black clouds come and then it rains heavily.

The weather gets a little cold. In the afternoon it will be sunny, the sun will begin to shine, and it will be

summer at the time of a day.

     In England, people can also have summer in winter, or have winter in summer. So in winter they can

swim sometimes, and in summer sometimes they need to wear warm clothes.

     When you go to England, you will see that some English people usually take an umbrella or a raincoat

with them in the sunny morning, but you should not laugh at them. If you don't like an umbrella or a raincoat,

you will regret (后悔) later the day.
