The English are famous for their tea and weather. The English are always talking about their weather. English weather is never the same two days running.

The most beautiful time in Great Britain is the spring and early summer. All the cold winds, the fog and heavy rains have gone. It rains sometimes, it's often cloudy, but not so often as in the winter. It rains quite often during all the year in England. It's a green country with green grass and large gardens.

The autumn is a nice season. The sky is blue and the sun shines all the day. After spring comes short English summer. It's a time of journeys to the seaside to bathe in the sea.

The winter has no snow at all sometimes. But it's not the right statement for the North and Scotland. It's nice time for skating on rivers. The west is warmer than other parts of the country.

It's a difficult country for people who work outdoors. They are milkmen, farmers, postmen and policemen. It could be cold in the morning, warm in the afternoon and raining in the evening. One day it's sunny, next day it may be cold, and the next day it may be rainy.

The most terrible weather is the foggy weather. Sometimes the fog is thick and dirty. In London this is called smog: a mixture of smoke and fog. Sometimes it's so dark that people can't see the way and cars crawl along slowly with their lights-on.

Everybody in England hates to wake up in the morning and look through the window to see the fog on the street. "Terrible" weather say 20 million Englishmen, when they go to work in the morning.
