三、READING COMPREHENSION (Please read the following passages and answer the questions. Choose the best answer for each question.) (I) The three phrases of the human memory are the sensory memory, the short-term memory, and the long-term memory. This division of the memory into phases is based on the time span of the memory. Sensory memory is instantaneous memory. It is an image or memory that enters your mind fleetingly; it comes and goes under a second. The memory will not last longer than that unless the information enters the short-term memory. Information can be held in the short-term memory for about twenty seconds or as long as you are actively using it. If you repeat a fact to yourself, that fact will stay in either it is forgotten or it moves into long-term memory. Long-term memory is the almost limitless memory tank that can hold ideas and images for years and years. Information can be added to your long-term memory when you actively try to put it there through memorization or what an idea or image enters your mind on its own.
