Many people from overseas believe that it rains a lot in London, but in fact its rainfall is similar to that in other European cities. Rainfall is evenly (平均地) spread during the year, so  even in summer a visitor is likely to experience some     weather. In spring and autumn there are likely to be some heavy showers, often followed by sunshine. In winter the rain is usually lighter but may    for longer.

In the summer, if there are a few days of particularly hot weather, these are often

   by a thunderstorm. It is because the weather can change very quickly that many British people carry a(an)umbrella with them throughout the year, even when it appears to be a

   day.

The UK’s weather is strongly influenced by the sea which surrounds Britain and Ireland. The sea warms up and       more slowly than land, keeping winters relatively warm but also making the summers cooler.

You may be wise to bring      warm to wear in the evenings even during the summer months. Very hot days (over 30 C) are not common, so air conditioning is not as widespread as in warmer countries.

During the winter people will often wear several different layers (层) of clothing. This allows them to keep warm when walking outside, but to     comfortable when inside a heated building.
