Question 18 is based on the recording you have just heard.

Recording One

    Have you ever had someone try to explain something to you a dozen times with no luck—but then, when you see a picture, the idea finally clicks? If that sounds familiar, maybe you might consider yourself a visual learner. Or, if reading or listening does the trick, maybe you feel like you’re a verbal learner.

    We call these labels learning styles, but is there really a way to categorize different types of students? Well, it actually seems that multiple presentation formats, especially if one of them is visual, help most people learn.

    (16) When psychologists and educators test for learning styles, they’re trying to figure out whether these are inherent traits that affect how well students learn, instead of just a preference. Usually, they start by giving a survey to figure out what style a student favors, like visual or verbal learning. Then, they try to teach the students something with a specific presentation style, like using visual aids, and do a follow-up test to see how much they learned. That way, the researchers can see if the self-identified verbal learners really learned better when the information was just spoken aloud, for example.

    (17) But, according to a 2008 review, only one study that followed this design found that students actually learned best with their preferred style. But the study had some big flaws. The researchers excluded two thirds of the original participants because they didn’t seem to have any clear learning style from the survey at the beginning, and they didn’t even report the actual test scores in the final paper. So, it doesn’t really seem like learning styles are an inherent trait that we all have. But, that doesn’t mean that all students will do amazingly if they just spend all their time reading from a textbook.

    Instead, most people seem to learn better if they’re taught in several ways, especially if one is visual. In one study, researchers tested whether students remembered lists of words better if they heard them, saw them, or both. And everyone seemed to do better if they got to see the words in print, even the self-identified auditory learners. Their preference didn’t seem to matter.

    Similar studies tested whether students learned basic physics and chemistry concepts better by reading plain text or viewing pictures, too. (18) And everyone did better with the help of pictures.

18. What message does the speaker want to convey about learning at the end of the talk?

解析：B。录音后面部分讲到，在视觉辅助下，每个学生的表现都要更好，即使是那些自认为属于听觉型学习者的学生也同样如此。录音最后提到，在学习基本的物理和化学概念时，依旧是在图片辅助下的学生学得更好，B项表述符合此内容，因此选B。A项与原文意思相悖，需排除。C项说阅读纯文本比看图片更有效，与原文不符，故排除。D项说没有视觉辅助，科学概念很难理解，而文中只是说在图片辅助下会学得更好，属于过度推断，故排除。
