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 remendation 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 panies who will security mark your bicycle for you. They will then put your registration number and personal details on their puter 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.
