    Who would win in a competition to memorize numbers, a chimp(猩猩) or a teenager?The teenager? Think again.Scientists have proved that chimps perform better than human beings when it comes to this kind of problem. We may have to rethink what we believe about human memory.

Memory is our ability to learn something, save it and recall it when needed.Our memories are important to our sense of self, our personalities, and our ability to understand the world

Scientists say that there are different types of memory.There is short-term memory and long-term memory.Your short-term memory saves information for a few seconds or a few minutes.For example, the time it takes to compare the prices of a few items(物件)in a store.Long-term memory involves the information you try hard to keep, because it's meaningful to you.(an example is data about family and friends).And then there is visual (视觉的) memory and sound memory.But these are not hard and fast: scientists argue a lot about the nature of memory.

Scientists have also found that people memorize things in different ways.Some memorize better with the help of pictures.Others are helped more by sounds.One thing s for sure.If you can combine different kinds of memory together, you will remember a lot So why not try pictures with English words? At the same time, listen to recordings of the same group of words.This may help when it comes to memorizing it.

Imagination and association can be useful, too.By imagination, scientists mean to picture a word in your mind.Association means relating the word to something you have already known.
