I read an article about London in a m    yesterday.
London is one of the c    with a long history in Britain. It is also the b city in Europe. You can find some of the best theatres and m  of the world there, such as the National Theatre, the National Gallery(画廊) and so on. You may visit many places of i   there. Most of the old and f   buildings are o    the north bank of the River Thames. On the south bank, there are some fine m   buildings.
If you want to k     the people there better, you should learn more about the l   and the culture（文化） as well.
