Unit 4 Our memory

第五课时 Section B 1a-1d

I.阅读理解

Have you ever entered a room and suddenly forgotten why you went there? It is because the brain often considers going through a door as entering a new place. This causes you to forget your original purpose for a while.

This is just one example of how our memory works. Forgetting often makes people unhappy, but our brain can only work this way-by keeping a balance between forgetting something easily and remembering something clearly.

When learning new information, whether it's a challenging skill or the name of an object, the brain forms new connections between neurons（神经元）.The busier the neural map is，         .More and more information can be stored in your brain. But just as a smartphone slows down when it stores too much information, the brain also stows down when it has too much to deal with. It will actively forget some unused information or unimportant feelings by making neurons less connected. This helps prevent too much information and control terrible memories to keep people calm in daily life.

Forgetting also builds creativity. Long-term memories may make our thoughts and actions too rigid and prevent the brain from forming new ideas. When we repeat doing things in the same way, our brain will get used to old habits and thoughts.

Forgetting is sometimes considered a weakness, but it actually plays an important role. Bv clearing out unnecessary information, the brain can better take notice of the important information in order to help shape us and keep our mind healthy.
