【连句成篇】
How can we make ourselves safe
As teenagers, to learn how to make ourselves safe is
especially important. Here are some of my suggestions.
First, we are supposed to be careful when making
friends online, which may bring us unnecessary troubles.
Second, remember never to go swimming on our own in
the river or lake because doing that will probably put
ourselves into dangerous situations. Besides, in order to
eat healthily and safely, we’d better eat less junk food
and not eat food that goes bad, for it will do harm to our
health. At last, when traveling outside, take care of our
personal things and call the police for help in time if we
are in danger.
In short, safety must come first!
