下面长城的英语介绍主要从长城的重要性和特点进行阐述，具体如下：
The Great Wall is a symbol of the Chinese nation. It is more than 12,000 miles long and is one of the greatest buildings in the world. The Great Wall was built in the Qin Shihuang period. After successive additions and repairs, almost all of the Great Wall we can see now were built in the Ming Dynasty.
Looking at the Great Wall from a distance, it looks like a long dragon, circling between the mountains and mountains. Now, we have come to the foot of the Great Wall. This section of the Great Wall is built on Badaling, which is tall and sturdy. Everyone looking forward, every other part of the Great Wall, there is a lookout port, which was used to look out and watch the enemy in ancient times.
