原文：
Ms. Jones, David's teacher talks to David's father about David.
A: Mr. Williams, it seems that David is a bit[1] under the weather[2] these days. He looks tired all the time. And he would doze off[3] in class. I'm afraid you'd better take him to see a doctor.
B: Thank you for caring about David, Ms. Jones. He's ok. I know what the problem is. He's recently been going to bed too late.
A: When does he go to bed?
B: Er, around 11 o'clock, sometimes even later.
A: Well, that's too late. Please send him to bed earlier, say[5], around half past nine.
B: Ok. We'll do that. You know, David's mother and I are both freelancers[6]. We don't have a fixed schedule[7], so we often sleep late and get up late. Recently David seems to have also got into the bad habit of going to bed late[8].
A: But David has to get up very early. I'm really worried about his health and study.
B: Ok. I promise we'll try to change our habits - to set a good example for[9] David.

不良生活习惯（1）-晚睡
大卫的老师琼斯夫人和大卫的父亲谈论关于大卫的事情。
A: 威廉姆斯先生，大卫近来身体似乎不大好。他看起来总是很疲倦而且经常在课上打瞌睡。恐怕您最好得带他去看医生。
B: 谢谢您关心大卫的情况，琼斯夫人。他很好。我知道问题在哪。他最近睡觉太晚了。
A: 他通常什么时候睡觉？
B: 呃，十一点左右，有时候还晚一些。
A: 哦，那太晚了。请早点让他上床睡觉，比如说，九点半左右。
B: 好的，我们会那么做的。你知道，大卫的妈妈和我都是自由职业者。我们没有一个固定的时间表，所以我们经常是睡得晚，起得也晚。最近大卫似乎也养成了晚睡的坏习惯。
A: 但是大卫得很早起床。我很为他的健康和学习担心。
B: 好的。我保证我们会尝试改变我们的习惯，以为大卫树立一个好榜样。
