1.交通安全：
With the development of the modern technology,private car is no longer a luxurious thing for ordinary people,more and more people drive to work instead of going by bus.
The popularization of private car has many advantages.First, it is very convenient and time-saving ,you can drive your own car to the workplace instead of waiting for the crowded bus and afraid of being late for working.Second,it can also improve the traffic structure,and help to mitigate the stress of the traffic.Third, the popularization of private car can help to promote the car industry and any other interrelated industries.
I believe that in the future the private car will become the most important vehicle and we cann't live without it.
2. 用电安全： Rules for using electricity the right way.
1). DON'T plug a bunch of stuff into one outlet or extension cord.
It could damage the electrical system in your house or even cause a fire.
2). DO ask grown-ups to put safety caps on all unused electrical outlets.
Covering outlets will also help save energy by stopping cold drafts.
3). DON'T yank an electrical cord from the wall.
Pulling on a cord can damage the appliance, the plug or the outlet.
4). DO make sure all electric cords are tucked away, neat and tidy.
Pets might chew on electrical cords, and people might trip and fall.
5). DO ask a grown-up for help when you need to use something that uses electricity.
6). DO look up and look out for power lines before you climb a tree.
The electricity can go right through the tree branch - and right through you!
7). DON'T ever climb the fence around an electrical substation.
If a ball or pet gets inside the fence, ask a grown-up to call the electric company - they'll
come and get it out for you.
8). DO remind your mom or dad to watch out for power lines when they're using a ladder,
chainsaw or other outdoor equipment.
9). DO keep electrical stuff far away from water.
Most electrical accidents around the house happen when people use electricity near water.
10). DON’T fly a kite near power lines.
The kite and the string may conduct electricity-sending it right through you to the ground.
