Some people are very forgetful,while others can remember everything they have done.Scientists know a lot about how our brains store and remember facts and experiences.There is little research on how or why the brain forgets things.
    A new study looks at forgetting.A team of researchers from the USA studied the brains' process of forgetting things.The researchers are cognitive neuroscientists(认知神经学家).They study the brain and how it thinks and works.
    Their work may help people who have memory problems.It may also help those with depression(抑郁症)and dementia(痴呆).The lead scientist,Marie Banich,said,"It sounds surprising that people can control what and how they forget."
    Professor Banich said forgetting is important.She said it keeps the brain working smoothly.Her research found ways that people remove information from their brain.She said, "We have control over the ability to get rid of information from our thoughts." This is important because it means we can focus on more important tasks.
    However,although we can control what and how we forget,the act of forgetting needs a lot of effort,which is also very surprising.Another researcher,Sara Festini,agreed.And she said,"We have found that intentionally(故意地)forgetting no-longer-relevant information from the mind is beneficial(有益的),but it doesn't happen automatically(无意识地)."Researchers will now look at why we forget recent events,like where we left our keys.
