关于长城的介绍，英文，初中水平

The Great Wall stretches over approximately 6,400 km (4,000 miles)[3] from Shanhaiguan in the east to Lop Nur in the west, along an arc that roughly delineates the southern edge of Inner Mongolia, but stretches to over 6,700 km (4,160 miles) in total.[4] At its peak, the Ming Wall was guarded by more than one million men.[5] It has been estimated that somewhere in the range of 2 to 3 million Chinese died as part of the centuries-long project of building the wall.[6]

The Great Wall is one of the seven wonders in the world.It has a lot of tourists every year.People who haven't visited it if they come to China will be laughed at by others.再结合上一段回答
