John的眼睛最近很不舒服，总是觉得很痒，看东西也很不清楚。
因此今天妈妈陪她来医院看眼睛。

Doctor: What's the matter?
John: Something is wrong with my eyes.
They itch and I can't see clearly.
Doctor: Oh, let me have a look. Look up. Look down.
Hmm, you've got some pimples on your eyelids. It's trachoma.
（原来是得了沙眼啊！pimple就是小疙瘩的意思。）
John: Trachoma?
Doctor: Yes. Do you often rub your eyes?
John: Oh, yes.
Doctor: You shouldn't do that. Your hands are dirty,
and rubbing your eyes can cause infection.
John: I see. I'll stop.
（大家可千万别再用脏手揉眼睛了哦！）
Doctor: Here is the subscription. Use these eye drops 3 times a day.
Come to see me in a week. .
John: OK. Thank you.
（“处方”就是subscription哦！）

看了John的故事，大家以后可要注意用眼卫生了，
等到眼睛生病闹罢工了，那可不好受了！
