     _1   Scientists and experts have proved the uniqueness of finger-prints and discovered that no exactly
similar pattern is passed on from parents to children,though nobody knows why this is the case.
    The ridge (隆起) structure on a person's fingers does not change with growth and is not affected by
surface injuries.Burns,cuts and other damage to the outer part of the skin will be replaced in time by
new one,which bears a reproduction of the original pattern._ 2    Some criminals make use of this fact to
remove their own finger-prints but this is a dangerous and rare step to take.
     Finger-prints can be made very easily with printer's ink.They can be recorded easily.  _ 3 Because of
the simplicity and economy of this system,finger-prints have often been used as a method of solving
criminal case.A suspected man may deny a charge but this may be in vain.    4 When a suspect leaves
finger-prints behind at the scene of a crime,they are difficult to detect with the naked eye.
