(C)
Sometimes people recall past events differently from how they happened. Have you ever confused dates and events from your life, or people’s names? Don’t be too hard on yourself if this is the case; it happens to almost everyone. Every day, our brain processes an amazing amount of information. In fact, all our experiences are based on the way our brain interprets the information it receives from our senses. It is impossible to store all of this information, so some of it gets lost. The parts that remain make up our memories. All our thoughts and memories depend on the way our senses work, and we cannot always trust everything our senses tell us.
If you have ever tried to make your own short film on a digital camera, you will have noticed that the images you record are often blurry(模糊不清). To stop the same thing from happening when we see things with our own eyes, our brain is always filling in the blanks. Before our eyes can even focus on an object, our brain has created its own picture of it so that we can move smoothly from looking at one thing to another without the world looking strange. If we are moving quickly or are not focusing properly, our brain may not correctly guess what is around us.
Memory is the way we store the information that our senses have experienced. As we have discussed above, our senses do not always see things accurately, so our memory is just how we store our interpretations of these experiences. When our brain takes in new experiences, it uses the information we retrieve from our memory as a reference. This means that we often do not remember the details of things but just the important parts. When we look at something, we often do not really look closely at it, but we merely look at the different hints that help us indentify it.
This also happens with our hearing and speaking. It is natural for students of English to confuse the word “kitchen”, with the familiar word “chicken”. As the sounds are similar, the mind mistakenly identifies the new word with the one that is familiar. This is perhaps the most common reason why people make mistakes when they learn a new language.
