比萨斜塔为什么是斜的英语？

The Leaning Tower of Pisa is slanted due to a structural defect that occurred during its construction. As the tower was being built in the 12th century, the soft soil underneath the foundation caused one side to sink, resulting in the characteristic tilt. Despite efforts to correct the tilt over the years, the tower still leans at an angle of about 4 degrees today. This unintentional tilt has actually become a major tourist attraction and a global icon. The tower's unique design and historical significance make it a must-visit landmark. It serves as a reminder of the engineering challenges faced by its builders and showcases the perseverance of human creativity.
