Drawing might help you think
When you’re sitting in class, have you ever drawn pictures in the margins of your notebooks
If so, your teacher might have told you 151 (stop). Many people think of doodling (涂鸦) as a distraction (精神涣散) from more important things. But it might be just the opposite.
One study shows that doodling may help you 152 (remember) things you hear. In 2009, researchers asked two groups of people to listen to a phone message. One group was encouraged to doodle, but the other was not. Neither group 153 (know) that it would be asked to remember information from the message. But the group that doodled remembered 29 percent more.
Other people have suggested other uses for drawing. Jesse Prinz is a professor who studies doodling. He 154 (say) it can help you think creatively. Walking away from a problem to draw might actually help you solve it. When you come back, you 155 (have) a fresh perspective (思考方法) and figure out an answer more quickly.
Two years ago, Sunni Brown wrote a book on doodling. She argues that doodling is a tool that can help people think. She admits that people see doodling as 156 (do) nothing, but she wants to change that. In fact, she runs a business that helps companies improve organization and planning through doodling. Brown believes doodling is helpful because it incorporates (整合) many ways of learning. You learn in four ways: seeing, hearing, reading or writing, and through movement. The more ways you use, the better you learn.
And when you doodle while you 157 (listen) to a lecture, you use all four.
You might think that being good at drawing is important for doodling. But if the point of doodling is to help you think, then it doesn’t matter what the picture looks like. Even if you’re not an artist, doodling can help you. So next time you need help focusing, 158 (pick) up a pen and doodle away!
