to take a picture, then they hurry away. The tower has 294 steps. Visitors who can climb to the top and

come down will feel like heroes.

     Engineers say that the visitors are safe, though the tower cloes lean. This tower has been leaning for

about eight hundred years. And it leans a tiny (微小的) bit rnore every year."If this keeps on. the tower

will fall at last. But many engineers are trying their best to keep the tower standing as long as possible.
