Unit 15　请假条

请假条包括病假条、事假条、续假条等。写请假条主要把请假原因和请假时间写清楚，请
假的理由要讲充分。同时也要注意内容要简单明了，开门见山说明情况，不必赘述。如果
有证明请假原因的证据，如医生证明、电报等最好随条附上。

1. 请病假（本人写）　Asking for sick leave written by oneself
(Sept. 17, 2004)
Dear teacher [Zhang],
I am very sorry to apprise you that I am unable to attend school today owing t
o a [stomachache]. I enclose doctor’s certificate and ask you for sick leave
of [two] days.

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 lo
t and had a high fever at [9 last night] and could not fall asleep until [midn
ight]. 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 tomorro
w].
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 certi
ficate from the doctor who is attending on me, as [she] fears it will be anoth
er [two] days before I shall be able to resume my study. Please give an extens
ion of leave for as many days.
Your student,
