22.Britain and France are separated by the English Channel, a body of water that can be crossed in as few as 20 minutes.But the cultures of the two countries sometimes seem to be miles apart.Last Thursday Britain and France celebrated the 100th anniversary(周年紀(jì)念)of the signing of a friendship agreement called the Entente

Cordiality.The agreement marked a new beginning for the countries following centuries of wars and love-hate partnership.But their relationship has been ups and downs over the past century.Just last year, there were fierce disagreements over the Iraq war-which British Prime Minister Tony Blair supported despite French President Jacques Chirac speaking out against it.This discomfort is expressed in Blair and Chirac’s body language at

international meetings.While the French leader often greets German Chancellor Gerhard Schroeder with a hug(擁抱)，Blair just receives a handshake.However, some political experts say the war in Iraq could in fact have helped ties.The history of divisions may well be because of the very different ways in which the two sides see the world.But this doesn’t stop 12 million Britons taking holidays in France each year.However, only 3 million French come in the opposite direction.Surveys(調(diào)查)show that most French people reel closer to the Germans than they do to the

British.And the research carried out in Britain has round that only a third of the population believes the French can be trusted.Perhaps this bad feeling comes because the British dislike France’s close relationship with Germany, or because the French are not happy with Britain’s close links with the US.Whatever the answer is, as both sides celebrate 100 years of “doubtful friendship”, they are at least able to make jokes about each other.Here’s one: What’s the best thing about Britain’s relationship with France? The English Channel.(320 words)
