五、新素材·记忆升级攻略 任务型阅读
Are you good at remembering what you've learned at school? No one's memory is perfect.
Even the smartest people forget things. This does
not mean a person has a bad memory.
The brain has short-term memory and long-term memory. When we learn something new, it stays in our memory for around 20-30 seconds. This is our short-term memory. It can hold a small amount of information. If we repeat it and use it often, this information can move from short-term memory to long-term memory — memories are stored for a long time.
No one knows exactly how short-term memory moves to long-term memory. But one thing is for sure — practising, or repeating information, is one of the most popular methods of remembering. And scientists say that long-term memory will never fill up completely with memories in one’s lifetime.
Then why do we forget things? Forgetting unimportant things helps our brain to remember important ones. Our brain is always “cleaning out” useless information to make room for something more useful.
If you are interested in improving your memory, there are lots of simple things you can do, like eating healthily, sleeping well and exercising daily. In addition, it’s also important to challenge your brain. All you need to do is keep your brain healthy and active.
