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".
If something is "on the tip of the tongue" (Paragraph 4), ______.
选项 A、you say it in a polite way
B、you remember it all your life
C、you don’t want to write it down
D、you know it but can’t remember it
答案D
解析 词句理解题。on the tip of the tongue是个习惯用语，指“话到嘴边(却想不起来)”。事实上，本题所在句前一句已经用问句的形式对其意思进行了解释：Have you ever struggled... or fact(你曾经费力地去记起一个熟悉的名字或者事实吗)。除[D]项外，其余三项都属于臆造出来的干扰项。
