Reflections on the texts
Have you ever thought about how important your memory is? And have you ever complained that you have a bad memory？
We can also eat to aid our memory power. Whole grains, fruits and vegetables are excellent sources of glucose, the brain’s preferred fuel.
To get adequate rest is a low-tech way to improve memory. Sleep may allow our brain time to encode memories.
Basic organization helps us remember the boring stuff. For example, rather than trying to recall a random list of groceries, we can divide them into categories such as dairy, meat, and produce. For important tings like keys and money, we can set up a “forget-me-not” spot where we always keep them.
Secondly, research shows that different things are stored in different parts of the brain.Ideas, words, and numbers are stored in the left-hand side, while the right-hand side remembers images, sounds, and smells. In most people one side of the brain is more developed than the other,and this may explain why some people can remember people’s faces easily, but can’t remember their names.
Lastly, the more often you recall a memory, the more likely you are to remember it. If you don’t use it, you’ll lose it. A telephone number that you dial frequently will stay in your memory easily, but you will probably have to write down one that you use only now and again.

Script:
To many people advancing age means losing your hair and your memory. But is it true that the older you get, the less you remember?
Thirdly, we all remember exciting, frightening, or dramatic events more easily. This is because these experiences produce chemicals such as adrenaline, which boost your memory.
Some memory enhancement experts suggest we pay attention to what we want to remember. Then give some meaning to it We remember things when we focus on them whether we intend to or not.
Actually, in healthy people memory doesn’t deteriorate as quickly as many of us think.As we age, our memory mechanism isn’t broken, it’s just different. The brain’s processing time slows down over the years. Recent research suggests that nerve cells lose efficiency and that there’s less activity in the part of the brain that decides whether to store information or not.
For us students, I think memory is particularly important. If we lost the faculty of remembering, we wouldn’t be able to learn anything since learning unavoidably involves the use of memory. And if we cannot remember the knowledge we have learned, how are we going to use it after we graduate?
Although everyone is born with the capacity to remember things, some of us have better memories than others. There are people who are said to have a photographic memory and can remember anything they have seen only once. However, those of us who have a poor memory needn’t panic, for there are ways to improve our memory. Paying attention, associating facts with images, visualizing images, and relaxing are some of the ways that I find especially effective. But the great secret to keep our memory sharp is to use it as frequently as possible.
Human beings have amazing memories. Apart from all our personal memories about our own lives, we can recall between 20,000 and 100,000 words in our own language as well as possibly thousands more in a foreign language. We have all sorts of information about different subjects such as history, science, and geography, and we have complex skills such as driving a car or playing a musical instrument. All these things and countless others depend on our memory.
Interest in friends, family and hobbies does wonders for our memory. A sense of passion or purpose helps us remember. Memory requires us to pay attention to our lives, allowing us to discover in them everything worth remembering.
Possible Answers(for the teacher’s reference)
Memory, I think, is almost as important as air, water or sunshine to us. Without it, life cannot go on. We wouldn’t be able to do anything since completing any task, however simple it might be, requires us to remember certain procedures. Nor would we be able to communicate with people as we wouldn’t remember the words to express our ideas or feelings.
