根据短文内容，选择正确答案。
Being safe in your everyday life needs knowledge. If you remember the
following information, your life will be much safer.
● Always notice the environment around you. You shouldn't walk
alone outside. Make sure where the public phones are. If anything dangerous
happens, you can find them easily.
● Your bag should be carried towards the front of your body instead
of putting it on your back. When a bus is full of people, it is easy enough for a
thief to take away the things in the bag on your back.
● If you are followed by someone you don’t know , cross the street and
go to the other way, let the person understand that you know he or she is after
you. Next, don't go home at once. You are safer in the street , but it is
dangerous for you to be alone in your home or in lift(电梯).
● If you have to take a bus to a place faraway, try to get to the stop a few
minutes earlier before the bus leaves. This stops other people from studying
you. On the bus, don't sit alone. Sit behind the driver or with other people.
Don’t sleep.
