Question 11 is based on the conversation you have just heard.

M: (8) Mr. Brown’s lectures are so boring.

W: Yes, he is not a very exciting speaker, but the subject is interesting.

M: During every one of his lectures, I try to listen. I really try. But after about 10 minutes, my mind begins to wander and I lose concentration. But I see that you seem to be OK. How do you stay focused through the entire hour?

W: (9) Well, what I do is keep my pen moving.

M: What do you mean?

W: (9) It’s a method of active concentration I read about. One of the most effective ways to concentrate is to write things down. But it has to be done by hand, not typing on the keyboard. You see, writing by hand forces you to actually engage with what you’re learning in a more physical way.

M: Do you review your notes afterwards then?

W: Sometimes, but that’s not important. My notes may or may not be useful, but the point is that by writing down what Mr. Brown says, I can follow his line of thinking more easily. In fact, sometimes I draw a little too.

M: You draw in class and that helps you pay attention?

W: Yes, honestly it works for me. I just draw little lines and nonsense really. It was also in that article I read. (10) It can keep the mind active, prevent getting bored and help to concentrate. Again the point is to listen hard while keeping the pen moving. (11) If I’m at home and I need to study, what I do is read out loud. It has a similar effect to writing by hand. It helps memorize information in a physical way.

解析：B。女士在对话的最后说到，如果她在家学习的话，会选择大声朗读。大声朗读的效果类似于书写，能够以物理的方式帮助记忆信息。故正确答案为B。D 项利用effective 和writing 作干扰，但原文说的是大声朗读和书写的效果类似，并没有说明大声朗读比书写更有效，故D 项错误。
