　　2. 请病假（代写） Asking for sick leave written by someone else

　　[Oct. 8, 2004]

　　Dear [Miss Willams],

　　Please excuse [Kate]’s absence from school [this morning]. [She] coughed a lot and had a high fever at [9 last night] and could not fall asleep until [midnight]. I felt it would not have been fair to the other children to allow [her] to attend school. So I am writing to ask you for [two] days’ sick leave and will let [her] resume [her] study if [she] feels better [the day after tomorrow].

　　Yours respectfully,

　　[威廉斯小姐]：

　　请原谅[凯特][今早]不能到校上课。[她][昨晚9时]发烧并咳嗽的很厉害，一直到[半夜]才入睡。我觉得叫[她]去学校会影响其他孩子，现代请病假[两]天。如果[后天][她]感觉好些，再让[她]到校。

　　3. 续假条 Asking for an extension of leave

　　Prof. [Huang],

　　I am still lying in bed with the [flu] and unable to get up. I enclose a certificate from the doctor who is attending on me, as [she] fears it will be another [two] days before I shall be able to resume my study. Please give an extension of leave for as many days.

　　Your student,

　　[Li Ming]

　　Encl . : Doctor’s Certificate of Advice

　　（黄）老师：

　　我患[流感]未好，仍卧床不起，医生认为，还要休息[两]天才能到校学习。现附上所开的证明，请准予续假为盼。

　　4. 教师的回假条 Teacher’s reply

　　Dear [Alice],

　　Your [mother] tells me you have the [mumps] and must be absent for [half a month]. There are several others in the same condition. Do be careful while you are ill. Don’t think of doing any homework. We’ll have reviews when the sick ones all return. You can watch television or listen to radio programs to help pass the time while you recuperate. I asked (Sue) to bring you several [pop music tapes], as [she] said you have a [tape-recorder] at home. I think you might find them nice.

　　We all miss you and shall be happy when you return.

　　Yours truly,

　　亲爱的[艾丽斯]：

　　你[母亲]告诉我，你患[腮腺炎]，必须休假[半个月]。还有几个同学情况也是这样。在生病期间，要多注意休息，不要去想做作业。等生病的同学都回来了，我们将进行复习。你可以看看电视或听听广播，以便帮助你在养病期间消磨时间。我已经叫[苏]给你带去几盘[通俗歌曲盒带]，因为[她]说你家里有一台[录音机]。 我想你会觉得它们很好听。

　　我们都很惦念你。当你回来时，我们将很高兴。
