1 . IV. Read the following passage and correct the mistakes.

A ta(榻) is a kind of Chinese furniture. It looks

like a bed, but smaller or lower to the ground. One                      1    
can either sit or sleep on them. The ta was first used                      2    
during the Western Han Dynasty (206 BC-AD 24).
At that time, it was for sit only and usually for guests.                     3    
To save space, people usually hung their ta on the wall.
When guests come, they would take the ta down                           4    
from the wall for the guest to sit. So at first，“Xiata”，                   5    
or taking down the ta, meant one had guests coming.
Later, it came to mean to stay somewhere that is not
home, such as in a hotel.
