听力原文：W: Hi. Tom. How things get along with the preparation for the annual meeting documents？

M: It's coming along. But I've been staring at the computer screen for hours and my eyes hurt. W: Yeah Typing the words on the screen really make your eyes dry and tired. You should take a break. M: I can't. The deadline is approaching. W: You know, I read about computers and eye problems recently. The article says that they are usually caused by not blinking your eyes enough. M: Blinking？ I thought I just needed new glasses. W: when you blink, the movement of closing and opening your eyes, even though it happens really fast relaxes your eyes. M: That makes sense. W: People using computer tends to stare at the screen and blink less often than they normally would. M: That is what I am doing. And I am suffering from the dry eyes. W: That is one of the typical symptoms. M: But what does it have to do with the computer？ W: The article I read about the office workers found that the workers averagely blink 22 times a minute when relaxed But just 7 times a minute while looking at the text on a computer screen. M: Wow That's quite a difference. W: Yeah. So you need to blink your eyes and take a break from the computer M: I wonder if using some kind of eye-drops will make me feel better. W: That might help.But the best prescription is to take a break and rest your eyes M: Ok. Let's go get some coffee. I can finish this later tonight. (23) A．Something goes wrong with his computer. B．He can not finish the documents in time. C．The computer screen is hurting his eyes. D．He can not understand the article.
