概要写作阅读下面短文，根据其内容写一篇60词左右的内容概要。Getting rid of dirt，in the opinion of most people，is a good thing.However，there is nothing fixed about attitudes to dirt.In the early 16th century，people thought that dirt on the skin was a means to block out disease，as medical opinion had it that washing off dirt with hot water could open up the skin and let ills in.A particular danger was thought to lie in public baths.By 1538，the French king had closed the bath houses in his kingdom.So did the King of England in 1546.Thus began a long time when the rich and the poor in Europe lived with dirt in a friendly way.Henry ，King of France，was famously dirty.Upon learning that a nobleman had taken a bath，the King ordered that，to avoid the attack of disease，the nobleman should not go out.Though the belief in the merit(好处) of dirt was longlived，dirt has no longer been regarded as a nice neighbor ever since the 18 century.Scientifically speaking，cleaning away dirt is good to health.Clean water supply and hand washing are practical means of preventing disease.Yet，it seems that standards of cleanliness have moved beyond science since World War .Advertisements repeatedly sell the idea: Clothes need to be whiter than white，cloths ever softer，surfaces to shine.Has the hate for dirt，however，gone too far?Attitudes to dirt still differ hugely nowadays.Many firsttime parents nervously try to warn their children off touching dirt，which might be responsible for the spread of disease.On the contrary，Mary Ruebush，an American immunologist(免疫学家)，encourages children to play in the dirt to build up a strong immune system.And the latter(后者) position is gaining some ground.应用文写作(one possible version ) 报纸13期Dear Mr Brown,Our school is planning to hold a Canadian Culture Week event next month,when different kinds of activities abut Canadian Culture will be organized .I am writing to invite you give us a lecture about local customs and practices which are unique to Canada.We expect that our teachers and students could have a better understanding if Canada culture through your lecture.The lecture is scheduled to be held in the Lecture Hall from 9.am to 11.am on November 15th It would be our greatest honour if you could accept the invitation.I am looking forward to your early reply.
