In England, people often talk about the weather because you can experience (经历) four seasons (季节)
in one day. In the morning the weather is warm just like in spring. An hour later clouds come and then it
rains hard. The weather gets a little cold. In the late afternoon the sky will be sunny, and it will be like in
summer.
    In England, you can also have summer in winter (冬天), or have winter in summer. So in winter you
can swim sometimes, and in summer sometimes you should (应该) 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 (如果) you don't take an umbrella or
a raincoat (雨衣), you will regret (后悔) later in the day.
