Starting in l972，the National Park Service established a policy for forest fires calle Natural Burn．It was acknowledged that some forest fires，such as those caused by lightning were necessary for forests to maintain balanced ecosystems，so the fire should be allowed to burn．However, a big fire in Yellowstone National Park in l988 caused this policy to be abandoned since the fire was initially allowed to burn yet soon out of control．As a result，the fire of l988 destroyed much of Yellowstone，which is America’s oldest and most beloved national park．Massive areas of plants were destroyed，and large empty spaces and acres of burned and blackened trees greeted visitors．The rivers and streams were choked with ash，and the ecosystem of the park was changed beyond repair.

    In addition，great numbers of animals were killed by the fires that bumed out of control. The fires were driven by high winds，moving as many as ten miles a day．Many small animals died in the flames．The fires’ rapid advances gave the wildlife little chance to escape. Even today，few of these small forest animals have returned to live in the park. In the years immediately following the fires，the numbers of visitors declined rapidly．No one was interested in seeing a blackened and treeless park on vacation．Yellowstone had previously been famous for its amazing views and unique geological formations such as the geyser Old Faithful. But now its reputation as America's wonder is damaged permanently.

There are many differences between British English and American English.I used to teach a course about the differences between the two.We speak English on both sides of the Atlantic Ocean but we have many differences in our common language.We have examples of the same words having very d ifferent meanings，differing spellings of the same words as well as completely different words for the same things.Here are some examples.

A cookie in the US is called a biscuit in the UK.A biscuit in the US is a small cake in the UK.Crisps in the UK，are known as chips，but we British people eat a plate of chips that you call fries in the US.In the UK，a pie can be made from either meat or fruit，while in the US pies are normally made from fruit；pot pies are made from meat.Most things are measured in grams and kilograms in the US，not pounds and ounces.

One very obvious(明显的)difference is the side of the road we each choose to drive on.Petrol in the UK is gas in the US.The place where we fill up our cars，in the UK，is a garage；while in the US，it’s a gas station.The term garage is also used as a place to store your car next to or close by your house.In the UK we call a lorry what is known as a truck in the US.

An elevator in the US is called a lift here，and the first floor in the US，is calle d the ground floor here，so many visitors get off on the wrong floor in British hotels.

I could continue with this. There are countless examples of differences within our one shared language.With so many differences，no wonder it’s hard to understand each other well.
