We've all been there--staring at a book，hoping that what we study will stick in our mind.Many of us have probably wondered，"Is there any way to improve memory？" So，why don't we look at what memory experts say about this？
   Every student knows that it's helpful to review what they've studied before.According to experts，we can learn things better if we wait some time before trying to study them again.They say that trying to retrieve （記起） something after you have had some time to forget it will make it easier to remember in future.
   Similarly，studies have shown that taking some time to just do nothing after studying might mean that you can remember things better afterwards.It is not clear why this happens.But some think it has to do with the relationship between long-term （長期的） and short-term memory.
   Another study tip is to change between different topics as you study.This can help you make connections between different ideas.Now，connecting them to each other or to images（圖像） is often considered a good way to remember something.The world memory winner Jonathan Hancock says how picturing pieces of information in different places or connecting them to memorable images makes them easier to remember.
   There are also more things that we can do to improve our memory.Hancock says that being generally organized makes things easier for your brain.Many other experts also suggest that we should get a lot of rest and exercise.So，the good news to take from this is that while it may be hard，improving our memory is something we can do.
