根据短文判断下列句子的正确(T) 与错误(F)。

     Your home is a safe place, right? Think again. 

     Many serious accidents happen in people's homes. 

     Could you please prevent these accidents? Yes. Many accidents happen because people are careless.

So be careful! Here are some tips about safety. 

     Don't stand on chairs. Many people may fall off chairs and hurt themselves. 

     ●Keep the floor dry, and you won't slip (滑) or fall. 

     ●Be away from matches. Even a cigarette (香烟) can easily start a fire. Don't use water to put out fires.

Use salt instead. 

     ●Be careful with knives! Many people cut them- selves in the kitchen. Never touch the broken bottles,

doors or windows. Glass can also cause the most senous cuts. 

     ●Don't keep poisons (毒药) in the kitchen. 

     ●Never use electrical appliances (电器设备) in the shower. Dry the floor before you use them, or electricity

can hurt you! 

     ●Keep children away from hot water and hot drinks. They can be dangerous. But adults often forget it. 

     ●Look through the peephole (门镜) when you hear the knock on the door. Don't let strangers in.
