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 (安全) Do not leave your bicycle in out-of-the-way places. Always lock your bicycle when you leave. Secure (绑住) it to lampposts (街灯柱) 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 (推荐) from a bike shop. Marking Security marking your bike can act 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 (注册) 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. 51. Which part of the text gives you information on how to lock up your bicycle when you leave it? A. Locks.B. Marking.C. Registration.D.

This even was started by Jennifer Barlow of Midlothian, Virginia in 2003, and it is becoming more popular each year. It has been supported by the International Dark-Sky Association, the American Astronomical Society, and the Astronomical League. This even always occurs in April, during the week of the new moon so that the sky can be as dark as possible for the best viewing conditions. “It is my wish that people could see the night sky without other light in the sky as our ancestors (祖先) saw it hundreds of years ago,” explains Barlow. Since it only lasts a week and not everyone in the country will take part in it, how will the National Dark-Sky Week reduce light pollution? The main goal of NDSW is to increase awareness (意识) of the harmful effects of light pollution. It is not possible for all of the light pollution in this part of the world to disappear. However, it is possible to make a small difference in the quality of the night sky. Another goal of this even is to promote (促进) the use of better lighting systems that direct light toward the ground instead of up into the sky. (责任编辑：admin) |
