问题     There are three kinds of memory: sense memory, working memory, and long-term memory. Think of them as three connected rooms in which you store different kinds of memories.
   The first kind of memory is sense memory. Everything you are sensing right now is stored here. Perhaps you feel the sun on your face or smell the aroma(香味) of food. Sense memories last only a few seconds, but they connect one moment to the next. They give your life a flow, even though they are quickly forgotten.
   You keep a few items(条目) in working memory. These are memories you need for what you are doing. Suppose you look up a friend’s telephone number in the phone book. You’ll probably remember the number for a little while. But if you get distracted(分神), you might quickly forget it. A memory usually stays in your working memory for just a few days at most. Working memory has another limit, too. Only a small number of items fit into it at any given time.
   Memories you want to keep for a long time go into your long-term memory. They can stay with you all your life. In long-term memory, you can store a huge number of items. Can you remember how to play your favorite game? Do you recall your first birthday party? If so, you are bringing up memories that are stored in your long-term memory. Sometimes, people have trouble finding a particular long-term memory. Have you ever struggled to remember a familiar name or fact? When this happens, people sometimes say the information is "on the tip of the tongue".
What does the author say about working memory?
选项 A、The number of stored items is limited.
B、The information contained is lasting.
C、It stays only while you work.
D、It stores numbers quickly.
答案A
解析 细节题。短文第三段说明的是working memory(工作记忆)。其中最后一句指出：Only a small number of items fit into it at any given time(任何时候都只有少量信息适合于它)，也就是说，工作记忆只能储存少量信息。这与[A]项的意思是一致的。其余各项都与这一段的说明不符。
