W: Hi, Rex. How’s your history paper going?
M: It’s coming along. But I’ve been staring at this computer screen for hours and my eyes hurt.
W: Yeah, doing that can make your eyes feel really dry and tired. You should take a break.
M: I can’t. I have to get this paper written. It’s due tomorrow.
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 helps moisten your eyes. It’s the lack of moisture that causes the problem.
M: Oh, that makes sense. But what does it have to do with the computer?
W: People who use computers tend to stare at the monitor and blink less often than they normally would. That leads to dry irritated eyes.
M: Well, I hope this news can help my eyes now. They really hurt.
W: The article I read about office workers found that the workers averaged 22 blinks a minute when relaxed, but just 7 a minute while looking at text on a computer screen.
M: Wow, that’s quite a difference.
W: They also kept their eyes open wider, which means that moisture evaporated more quickly.
M: I wonder if using some kind of eye drops would make them feel better.
W: That might help. But the best prescription is to take a break and rest your eyes.
M: OK. Let’s go to get some coffee. I can finish this later tonight.
Questions 23 to 25 are based on the conversation you have just heard.
23. What are the speakers talking about?
24. Why is blinking important?
25. What should Rex do to improve his situation?

选项 A、Problems the man has encountered when writing his history paper.
B、The man’s broken computer.
C、The reason why staring at the computer screen makes eyes hurt.
D、The woman’s article on the newspaper about eyes.

答案C

解析 选项概括性强表明,本题可能考查对话主题。对话中男士提到的staring at this computer screen...eyes hurt,女士提到caused by not blinking your eyes enough,随后进行了具体解释说明:lack of moisture,stare at the monitor and blink less often...leads to dry irritated eyes,kept their eyes open wider...moisture evaporated more quickly,由此可知,对话双方主要讨论了为什么盯着电脑屏幕会使眼睛不舒服这一话题,故答案为[C]。
