Ladies and gentlemen，
Welcome to the Great Wall。 The Great Wall of China is one of the wonders of the world。 It is one of the few man-made objects on earth that can be seen on the moon。
It dates from about 770 BC。 It is more than 6000 kilometres long， 6-7 metres high and 4-5 metres wide。 All the work was done by hand。
Many people were forced to work on the wall。 Now the Great Wall has become a place of interest。 We all know the famous Chinese saying: “He who does not reach the Great Wall is not a true man。
” Now let me show you around the Great Wall。 This way， Please。
