We all know that theme parks are places to have fun and amuse ourselves, but among so many exciting rides there are also some dangers, Make sure you know what the safety standards are for all the attractions at the park. If you do that , you will be safe and have fun.

Drink water. Believe it or not , dehydration-- when your body doesn’t have enough water--is the commonest cause of injuries at theme parks. Drinking water while you are at the park is not enough.You must make sure that you drink enough water before your visit.

Use your “common sense”. There are lots of people around , so make sure where your friends or family are .Also ,if you are walking and want to stop , make sure nobody is walking behind you. First step aside,then look behind and if you aren’t in anybody’s way,then stop.It might sound exaggerated(夸张的),but crashes between people can cause accidents.

Follow the instructions. The majority of theme parks have instructions for each ride. Some rides only allow people of a certain height. So make sure you are not too tall or too short before boarding any ride. Also, people with certain diseases or conditions are advised not to go on some rides. Do remember : If you are told not to go on a ride, then DON’T.

Do not ride with a bad atomach or if you’ve just eaten. Rides can make you ill because of their violent changes of direction and your lunch may end up on someone else’s head: surely not a very pleasant experience.

Have fun, relax, and be a little brave!

Some rides might look scary but theme parks are very safe places.
