Question 13 is based on the conversation you have just heard.

听力原文

M: Hi, Jennifer. I’m really struggling with this semester’s workload. Do you have any advice?

W: (12) [Have you considered making a study guide?] It’s a tool you can make yourself to take the stress out of studying. I’ve been using one since the start of last semester, and it has really helped relieve a lot of study pressure.

M: Sounds like just what I need. (13) [My main problem is that my study folder is full of notes and worksheets and is badly disorganized.] I don’t know where to start.

W: Okay. Well, the main thing is to have everything in the right place. Whatever you’re reviewing, it’s important that it’s arranged for your particular needs of that subject and in the most user-friendly way you can. What kind of learner are you?

M: Hmm...I’m not sure.

W: Well, visual learners prefer using images, pictures, colors and maps to organize information. Logical learners have a linear mind, and would rather use logic, reasoning and systems. (14) [I’m an emotional learner,] which means I need to connect to information emotionally to understand it.

M: Oh, I’m very much dependent on vision as a way of taking in information.

W: Well, (15) [I suggest reorganizing your notes using color-coded sections in your study guides, or using idea mapping to lay out the information and make it more quickly accessible.]

M: (15) [So you think I should arrange my notes using color and pictures in place of text.]

W: Yes, you’ll probably start to grasp information a lot quicker that way. As an emotional learner, I organize my notes into a story that I can connect to and recite to myself. 

M: That’s amazing. I didn’t know there were so many different ways to learn.

13. What is the biggest problem the man has with his studies?

解析：C。在录音中间部分男士提到，他主要的问题在于学习文件夹里（study folder）满满都是笔记和习题卷，一点条理也没有（badly disorganized）。C项与此相符，基本复现了录音中的原词，故为正确答案。 

错项排除：A项利用录音中的worksheets和badly disorganized设置干扰，但录音中说的是男士的学习文件夹毫无条理，而不是习题卷毫无条理，故A项错误。虽然男士在录音开头提到自己的课业量让他很头疼，没有提到课业量过于繁重，而且这不是他在学习上最大的问题，故B项排除。D项利用notes设置干扰，但录音中没有提到快速做笔记这件事，故D项排除。
