Every year, more than nine million people all over the world come to visit London. They go to the museums and theatres; they look at interesting old buildings or have a drink in a park.

    A quick and easy way to get to different places in the city is to take an underground train. The London underground is one of the best and most widely used transport networks（网状组织）in the world. The trains run all day and most of the night. (3)You'd better not take the underground between eight o'clock and ten o'clock in the morning, or four o'clock and six o'clock in the afternoon. (4) The trains are so crowded that you can hardly move or find a place to sit.

    London's famous red buses form a big part of getting around in London. Although the London underground is the fastest and the simplest way of getting around London, the buses play their part and are an experience you should try at least once. By sitting on the top deck (层) of the bus, you can get a great sightseeing (观光的)  experience of London as well.

    Some special visitors' buses take you to many of the interesting places in the city on one journey.  It takes about one and a half hours, but you can cancel your journey and get off (and on again) at the different places you want to visit.

    London taxis are called "black cabs”. Most of them are black, but some are not. You can stop one if it has a "For Hire (供租用的)n sign on it. The drivers are friendly and helpful.

    In a word, London is a big and beautiful city with Lots to see and to do. Welcome to London.
