阅读理解。
Being safe (安全的) at school and in your everyday life needs knowledge (知识). If you remember the
following information, your life will be much safer.
Always notice the environment (环境) around you. You shouldn't walk alone (独自) outside. Make sure
where the public phones are. If anything dangerous happens, you can find them quickly.
Don't use earphones (耳机) when running in the schoolyard or on the street. You will keep yourself from
the outside world and can be easily surprised.
School bags should be carried (携带) towards the front of your body instead of (而不是) putting them
on your back. When buses are crowded, it is easy enough for thieves to steal the things in your bags on your
back.
If you are followed by a stranger, cross the street and go in the other direction (方向), let the stranger
know that you know he or she is there. Next, go and get help from others if it is necessary. Don't go home
directly. You are safer in the street than you are in your home or in a lift.
If you have to take a bus to a place far away, try to get to the stop a few minutes before the buses leave.
This prevents (阻止) a stranger from studying you. On buses, don't sit alone (独自), sit behind the driver or
with friends. Don't sleep.
Don't play with matches (火柴) or candles (蜡烛), because it may cause fire. If your house catches fire
and you have to escape (逃跑) through smoke, move on your hands and knees with your head 30 to 60
centimetres (厘米) above the floor. Please remember there is cleaner, cooler air near the floor during the
fire.
