Some people see colours when they hear different sounds.Others see colours when they see words and numbers printed in black and white.These interesting people are called synaesthetes，and what they experience is called synaesthesia.
    A study at the University of Sussex is finding out how learning to see sounds as colours or think of letters in colour could improve your IQ and memory.One of the study leaders，Dr Bor says that carrying out these tests has given them the opportunity to find out more about how people use different kinds of memory.
    Dr Bor based his latest research around something scientists already know a lot about—" chunking".He explains that this is a way of breaking large pieces of information into smaller units，to make it easier to remember. "When I give you my phone number，01274737215，you probably remember it as 012 74 7372 15，or something similar.If you can remember 012 and the first 74，you can remember the rest.You can get some amazing benefits from chunking!"
    This is really important for understanding synaesthesia.Dr Bor says that synaesthesia adds extra information to things that are difficult to remember，such as letters and numbers，or extra colours.This helps us remember things better.And Dr Bor's own study of one amazing person，who has both synaesthesia and a very strong memory advantage，supports this idea as well.
    The study began as a way to test whether synaesthesia is connected to greater abilities to do certain things and aimed to create a way of learning synaesthesia to develop benefits for everyone.After training，people were able to pass the normal synaesthesia tests，and their IQ jumped up about 12 points!But Dr Bor says they need to test the increase in IQ with different groups of people apart from clever students who took part in this study.

（1）According to the passage，when do people experience synaesthesia？

People experience Synaesthesia when they see colours while hearing different sounds or seeing words and numbers printed in black and white.

People experience Synaesthesia when they see colours while hearing different sounds or seeing words and numbers printed in black and white.

（2）How can synaesthesia help improve memory？

By adding extra information to things that are difficult to remember，such as letters and numbers，or extra colours.

（4）Besides synaesthesia，what do you think are some other ways to improve your memory？（In about 40 words）

Possible answer：In order to improve our memory we can do new things and change our daily habits to keep our brain active.We can also try to memorize something new and play Maths puzzle to get lots of regular exercise.
