Almost all theme park accidents can be prevented．Here, based on coverage of theme park safety, are some tips to help you and your family stay safe on your next visit.

If you are visiting with a child, take a moment to explain the ride to them, and tell them what they should do．They are depending upon you to keep them safe．Set a good example for them by following the rules of the park, and make sure that they know you expect them to follow those rules, too.

Tell them to stay seated, to hold the grab bar or put their hands in the laps, and not to stick their knees and feet outside a ride vehicle．Make them look to you for the okay to get on or off a ride, too．And never put a crying child on a ride．If your child starts to cry, let others pass you in line until your child is calmed．Or, gently exit the queue and find something more relaxing to do． 

Young kids can’t keep an adult’s pace in a theme park．Let them take plenty of breaks.

“Kids get tired,” said TPI reader Matt Johnson, a father of four．“Tired kids make parents even more tired．And tired kids and parents may get hurt — physically and emotionally.” He advises that parents plan a mid-day break, perhaps a swim back at the hotel, to avoid mid-day heat and crowds．“You will see cranky families having a miserable time while you are refreshed and having a great evening.”

The term “multitasking” originally referred to a computer’s ability to carry out several tasks at one time. For many people, multitasking has become a way of life and even a key to success. In fact, some excellent mental aerobic exercises (大腦訓(xùn)練) involve engaging the brain in two or more challenging activities at a time. Although checking e-mail while talking on a phone and reading the newspaper may be second nature for some people, many times multitasking can make us less productive, rather than more. And studies show that too much multitasking can lead to increased stress, anxiety and memory loss.

In order to multitask, the brain uses an area known as the prefrontal cortex (前額葉腦皮層). Brian scans of volunteers performing multiple tasks together show that as they shift from task to task, this front part of the brain actually takes a moment of rest between tasks. You may have experienced a prefrontal cortex “moment of rest” yourself if you’ve ever dialed (撥電話) a phone number and suddenly forgotten who you dialed when the line is answered. What probably occurred is that between the dialing and the answering, your mind shifted to anther thought or task, and then took that “moment” to come back. Research has also shown that for many volunteers, job efficiency (效率) declines while multitasking, as compared to when they perform only one task at a time.

Multitasking is easiest when at least one of the tasks is habitual, or requires little thought. Most people don’t find it difficult to eat and read the newspaper at the same time. However, when two or more attention-requiring tasks are attempted at one time, people sometimes make mistakes.

We often don’t remember things as well when we’re trying to manage several details at the same time. Without mental focus, we may not pay enough attention to new information coming in, so it never makes it into our memory stores. That is one of the main reasons we forget people’s names---even sometimes right after they have introduced themselves. Multitasking can also affect our relationships. If someone checks their e-mail while on the phone with a friend, they may come off as absent-minded or disinterested. It can also cause that person to miss or overlook key information being passed on to them.

Why are some mental aerobic exercises designed to engage people in multitasking?

A. To make them more productive.     

B. To reduce their stress and anxiety.

C. To develop their communication skills.

D. To help them perform daily tasks more easily.
