八、阅读理解（每题2分，共10分）
Many people wish to have a good memory. But do you know how our memory works
When we learn something new, it first goes into our short-term memory. Short-term memory is like a small box. It can only hold a little information. If we don’t review the knowledge quickly, it will disappear soon.
If we keep reviewing, the information will move into long-term memory. Things in long-term memory can stay in our brain for years. Some sweet memories can stay with us all life.
Here are simple ways to improve memory.
First, take enough rest. Tired brains cannot remember well. Second, try to use pictures to help memorize. Third, review your lessons regularly. Remember: good memory does not come naturally. It needs training.
( )1. Where does new information go first
A. Long-term memory. B. Short-term memory.
C. Our heart. D. Our notebook.
( )2. What will happen if we don’t review new knowledge
A. It stays forever. B. It disappears quickly.
C. It becomes easy. D. It moves to long-term memory.

A. Two. B. Three. C. Four. D. Five.
( )4. Which of the following is TRUE
A. Short-term memory can keep things for many years.
B. We don’t need rest to have good memory.
C. Pictures can help us memorize things.
D. All people are born with good memory.
( )5. What is the main idea of the passage
A. How memory works and how to improve it.
