One possible version:
Good morning,everyone!I am Li Hua from Xingguang Middle School.
The topic of my speech is “Why was the Great Wall selected for inclusion in the UNESCO World Heritage List?”.?
As we know,the Great Wall was listed as a World Heritage by UNESCO in 1987.Located in the northern part of China,it was founded during the Spring and Autumn and Warring States periods.After Qin unified the country,it spanned thousands of miles.The Great Wall was originally built to defend against the attack of the enemy from the north.It is a wonder that was created by the ancient Chinese working people and is one of the greatest projects in the history of human beings.
In a word,all of this explains why the Great Wall earned—and deserves—
its place on the UNESCO World Heritage List.
That’s all.Thanks for your listening.
