     You may have heard of snipers (狙击手), or seen snipers in movies and computer games. They are

people who can shoot and kill from a long distance. But do you know that we have real snipers in our

police?

     Early this month, a man kidnapped a little girl with a knife in Beijing. Police came to talk to him, but he

didn't let the girl go and was hurting the girl. A sniper shot him dead.

     In Beijing, there are over 300 police snipers. They work 24 hours a day, seven days a week to protect

the capital.

    How do snipers get trained? What are their lives like? An expert (专家) with the Beijing sniper team shares

some of the team's secrets with us.

    Q: How do you choose snipers?

    A: We choose snipers from the Beijing police. There are no strict rules about the height and weight of our

snipers, but they must have very good eyesight. The weapon (武器) they use is around 3.5kg. Sometimes

snipers need to hold it for hours. So, snipers need to have a strong body. They also need to pass written

psychology (心理) tests.

    Q: What is the most important quality of a sniper?

    A: A good state of mind. Snipers need to be calm all the time. Sometimes, they may get ready for shooting

for a whole day. They cannot talk, eat or drink during that time.

    Q: What kind of training do snipers usually get?

    A: The practice they often get is 100 meters distance shooting. They practice shooting in all kinds of

weather, including windy and snowy days. 

    Q: Is it possible that a sniper may miss his target (目标)?

    A: That is not possible. The only standard (标准) for being a sniper is to take a life with one bullet (子弹).

    However, snipers are not killers. They only pull the trigger (扣动扳机) when they have to.
