Boating on River Thames was the most exciting experience of the day. Along the river are all kinds of buildings and places of interest which are famous or which were not familiar to us. We had got to know London tentatively. We passed under Tower Bridge and many other bridges crossing the river. We saw the Tower of London, Big Ben, the Houses of Parliament, Puckingham Palace, Trafalgar Square and so on.英国伦敦泰晤士河观光游船
