急！！！用英文介绍伦敦的红色双层巴士和黑色出租车（200词左右）

A double-decker bus is a bus that has two levels. While double-decker long-distance coaches are in widespread use around the world, double-decker city buses are less common. Double-decker buses are popular in some European cities and in some parts of Asia, usually in former British colonies. Many towns around the world have a few that specialise in short sight-seeing tours for tourists for, as William Gladstone observed, "the way to see London is from the top of a 'bus" (Gladstone was referring to London's once ubiquitous double-deck horse drawn omnibuses, rather than a motor bus).[1]
Double-decker buses are in common use throughout the United Kingdom, typically seating between 60 and 80 passengers and have become a symbolic image of the country in particular the use of the red double decker buses in London. They are between 9.5 and 10.9 metres in length and are useful as a means of carrying large numbers of passengers without exceeding legal limits on vehicle
