4 阅读理解 A lot of teachers hate doodlers(乱写乱画的人)during classes. "Pay attention!" Teachers will often warn doodling students, sure that they must be daydreaming. However, according to a recent study, doodling while listening to a boring lecture helps concentrate(集中)the attention: Andrade, a psychology professor in England asked participants to listen to a boring lecture. Half the participants were told to color in squares and circles freely on a piece of paper while listening to the lecture. The other half weren’t given a task. After it was over, the participants were asked to retell the lecture. Those given the doodling task (color in squares and circles) remembered 29 percent more information than the non-doodlers. Andrade said. "If someone is doing a boring task, like listening to a dull conversation, they may start daydream," said Professor Andrade. "Daydreaming distracts(使分心)them from the task, resulting in poorer performance. A simple task, like doodling, can stop them from daydreaming without affecting their performance at the task," he said. So the next time you"re doodling during a class, and you hear "pay attention", you can tell the teacher with confidence that you"ve been paying attention to every word． 1. The passage mainly tells us . A. doodling will be banned(禁止) in classes B. teachers are against doodling C. doodling may help concentrate D. doodling can lead to daydream 2. Teachers hate doodlers because they thought . A. doodlers are not good at study B. doodlers are doing no task C. doodlers pay no attention in class D. doo dlers are not polite to them 3. According to the text, it is helpful to doodle when . A. a boring lecture is given B. an interesting story is told C. watching a long TV program D. having a conversation with the teacher 4. Professor Andrade thinks . A. those given the doodling task can remember less information B. if you have daydream during classes you"ll have a good memory C. daydreaming is better than doodling D. doodling can stop us from daydreaming 5. We can learn from the text that . A. doodling is the best way to draw attention B. daydreaming is different from doodling C. doodling will be helpful in any occasion D. every student should doodle in class
