英文请假条写法：
首先，假条的上方还是应该按照半正式的格式写上如下信息：
to：假条是递给谁的
from：请假人
date：写假条的日期(注意不是请假的日期)
subject：写上请假字样
假条抬头范例如下：
to:
peter
stone,
manager
from:
lynn
chen,
financial
department
date:
april
2nd,
2004
subject:
casual
leave
of
absence
其次，在您的请假信第一段，应该开门见山但是有礼貌地提出请假。第一段要中心明确，写清您要请假的日期。
第一段范例如下：
peter,
i
would
like
to
know
if
i
could
ask
for
a
casual
leave
of
absence
for
one
day
on
april
4th,
this
wednesday.
然后，在假条的第二段，您应该简单明了陈述请假的原因事由。注意叙述清楚明白，并尽可能表示对此带来工作不便的歉意。
第二段范例如下：
this
morning
i
received
a
telephone
call
from
my
dentist,
urging
me
to
come
to
his
practice
for
immediate
treatment
of
my
teeth.
i
have
been
experiencing
a
stinging
pain,
depriving
me
of
my
sleep
during
the
past
fortnight.
the
situation
could
worsen,
should
infection
occur.
concerning
my
workload:
as
wednesday
is
not
as
busy
as
the
other
weekdays,
i
think
a
one-day
leave
this
wednesday
may
be
the
best
solution.
i
apologize
for
the
inconvenience
my
absence
from
work
may
cause.
接着，在假条的最后一段，应写上您希望获得准假的句子，或者具体等候答复的时间。
最后一段范例如下：
thanks.
i
will
call
you
at
1:30p.m.
or
you
can
call
me
at
any
time.
好，把以上几段综合起来，就是一则请假条。
