    Last year，Zhang Pingyu paid visit to London．Worried about the time available，Zhang Pingyu had made a list of the site she wanted to see．It was the Tower which she visited first．Fancy!This solid stone，square tower had been remained standing for one thousand years．Many new buildings had expanded around it．Therefore，it was still part of a royal palace and prison combined．There followed St Paul's Cathedral built after the terrible fire of London in 1666．It looked splendidly when first built．Westminster Abbey，too，was very interesting．Then just as he came out of the abbey，Pingyu heard the famous sound of the clock Big Ben，ring out the hour．
    The next day Pingyu was leaving London to Windsor Castle． "Perhaps I will see the Queen？" she wondered as she fall asleep．
