Pisa is an Italian city known for its Leaning Tower.
The Tower, interestingly enough, started leaning in the middle of its construction — when its first three stories were completed. Bonnano Pisano, the engineer in charge, tried to correct the lean by making the new stories slightly taller on the short side, only to find that the added marble caused the Tower to sink still further. Work was suspended several times as engineers sought fresh solutions, until the Tower was finished in the 14th century, still leaning. The construction, begun in 1174, nearly took 200 years.
In modern times the structure has been several times strengthened by cement, but to this day it is still in danger of collapse. Various schemes have been under consideration for saving, it. To rebuild an upright tower would be easy enough for modern engineering, but it would not be the same edifice as people love and remember it. The Leaning Tower must be left leaning, saved, not reconstructed
A. At the beginning of its construction.
B. In the middle of its construction.
C. When the construction was finally finished.
D. Nobody knows about it.

[单项选择]Everyone knows that in the city of Pisa in Italy there is a tower that "leans".
The tower is built entirely of white marbles. The walls are 13 feet thick at its base. It has eight storeys and is 179 feet high.
There is a stairway of 300 steps built into the walls, which leads to the top. At the top of the tower, you’ll see the city and the sea. The sea is six miles away.
At the top, the tower is 16.5 feet out of the perpendicular. In other words, it "leans" over by 16.5 feet. If you were to stand at the top and drop a stone to the ground, it would hit 16.5 feet away from the wall at the bottom of the tower!
What makes it lean Nobody really knows the answer. Of course, it wasn’t supposed to lean when it was built; it was supposed to stand straight. It was intended as a bell tower for the church nearby. The church was begun in 1174 and finished in1350.
The foundations of the tower were laid in sand, and this may explain why it leans. But it did not sud
A. stand straight
B. stand at an angle
C. lie down
