     Su Hua is studying at Cambridge, UK. She has bought a bicycle and is worried about security ( 安全). Her friend, Kate, found this article and sent it to her.
     Introduction
     A lot of crime is against bicycles. About 150,000 bicycles are stolen every year and most are never
found. You can prevent this happening by following a few careful steps.
     Basic Security
     Do not leave your bicycle in out-of-the-way places. Always lock your bicycle when you leave. Secure
it to lampposts or trees. Take off smaller parts and take them with you, for example lights and saddles (车座).
     Locks
     Get a good lock. There are many different types in the shops. Buy one that has been tested against
attack. Ask for a recommendation from a bike shop.
     Marking
     Security marking your bike can act as a deterrent to a thief. It can also help the police find your bicycle. It should be clearly written and include your postcode and your house or flat number. This will provide a
simple way to identify your bicycle.
     Registration
     There are a number of companies who will security mark your bicycle for you. They will then put your
registration number and personal details on their computer database. Then if your bicycle is found it will be easy to contact you.
     Finally
     Keep a record of the bicycle yourself： its make, model and registration number. You can even take
a photograph of it. This will prove the bicycle belongs to you.
