31. (阅读理解题)(二)
How often do you talk with people and notice that their words say one thing while their action says another? A facial expression, crossed arms or the way they behave can show what is really in their mind. This is body language, and we must teach our children to understand and use it.
We often teach children to be thoughtful when they speak and write, and we also need to teach them to be thoughtful in their body language. Giving examples is one of the ways to do that. Help children understand that people use body language most of the time in their life. Where they.re looking when they speak, how they turn their bodies, how they place their arms and so on can give others important information.
There will be times that people want and need to use their body language. In school or job situations, understanding body language can make a difference. And using body language in other situations is also helpful to personal safety and sometimes stops misunderstandings(误会).
