Question

The brain receives information from the outside world through the sensory (感觉的) system．This information is collected through the eyes，the nose，the ears，the mouth and the surface of the body．It is then kept in the memory．In fact，scientists do not completely understand how the memory works but they are not sure how much information that the human brain can store．Also， it appears that the information is never lost．Very old people often remember things that happened in their childhood which have not come to their minds for sixty to seventy years．If we have kept something in our memory, it is here．But can we get it out again and use it? That is the difficulty．

Some of the information we receive only goes into the Short Term Memory．We only keep this information for a minute or two，then we lose it．This temporary (暂时的) memory is very important in our thinking and understanding．It is used，for example，when you try to remember a name that someone told you a moment ago or a telephone number that you are going to dial (拨)．School children in class often seem to use the Short Term Memory if they are not interested in the subject．When school teachers describe this，they say that things go“in one ear and out in the other”．But if a child is interested，he puts the information in his Long Term Memory, and he never loses it．Long Term Memory depends heavily on our understanding of the meaning of the information we receive．

【解析】

试题分析：短文大意：大脑通过感觉系统接收到外部世界的信息。这信息是通过眼睛，鼻子，耳朵，嘴和身体表面来收集的。事实上，科学家们还不完全了解记忆的工作，也不确定人类的大脑可以储存多少信息。长期记忆在很大程度上取决于我们对收到的信息的含义的理解。

1.A细节理解题。根据短文开头The brain receives information from the outside world through the sensory (感觉的) system．This information is collected through the eyes，the nose，the ears，the mouth and the surface of the body．可知所以该选A。

2.B细节理解题。根据第一段中Very old people often remember things that happened in their childhood which have not come to their minds for sixty to seventy years．可知很老的人常常记得大约七十年前发生在他们童年的事情。所以该选B。

3.A细节理解题。根据第二段中School children in class often seem to use the Short Term Memory if they are not interested in the subject．When school teachers describe this，they say that things go“in one ear and out in the other”．可知上学的孩子对他们不感兴趣的东西很快就会忘掉，所以该选A。

4.短文最后一句Long Term Memory depends heavily on our understanding of the meaning of the information we receive．可知长期记忆在很大程度上取决于我们对我们收到的信息的含义的理解。所以该选B。
