Any

And
she

Brother:
But
the

pretty
clean
and
tidy!
Sister:

一、Make
polite
requests提出礼貌的要求
句型：Could
you
（please）
do
...？意为“麻烦你……好吗？”或“请你……行吗？”。
注意：表示请求帮助或请求允许的疑问句中，常用could代替can，表示礼貌，委婉或不确定，而can则不具备这些语气。这时不能把could看作can的过去式。
Could
you
please...？句型的否定结构是在please后加not。意思为“请你不要……可以吗？”。
eg：—Could
you
come
here
soon？你尽快过来，行吗？
—Sure.当然可以。
—Could
you
please
close
the
window？
请你关上窗户好吗？
—I’m
afraid
not.
恐怕不行。
常见表示委婉请求做某事的句型及其答语：
委婉请求：Could
you
please+
do
sth.?
Could
you+
do
sth.?
Would
you
please
+
do
sth.?
Would
you
+
do
sth.?
肯定回答：Sure.
/
Of
course.
/
No
problem.
/
I’d
love
to.
否定回答：Sorry.
/
Sorry,
I
can’t.
/
I’d
love
to,
but
…
注意：
无论肯定还是否定应答中，要避免使用could，要用can或may。因为应答须用确定的语气。
否定回答通常用委婉语气。通常先说sorry，再说原因。
二、Ask
for
permission请求许可
（1）句型：Could
I
...？意为“我可以……吗？”。
eg：Could
I
come
in？我可以进来吗？
（2）另外，用Could
I
...？时，表示请求对方准许，
对方回答时不能用could，而要用can。
eg：—Could
I
use
your
bicycle？我可以用你的自行车吗？
—Yes,
you
can.是的，可以。
（3）回答：
肯定常用语：Certainly./Of
course./With
pleasure./No
problem./
Sure./Yes，you
can.
否定常用：I'm
afraid
not./No，
I'm
afraid
I
can't./No，you
can't.
情态动词could的用法
情态动词could构成的句型用于向对方委婉地提出请求或征求对方的许可。
用于疑问句中，可代替can，在时间上与can没有区别，但语气要比can委婉、有礼貌。

(2)
①肯定回答：Certainly./Of
course./With
pleasure./
No
problem./Yes,
sure.
②否定回答：
No,
I
can’t./Certainly
not./
No,
I’m
afraid
I

you
please
make
your
bed?
—Yes,
sure.
2.
委婉地请求别人允许自己做某事（征求许可）
(1)句型：Could

(2)肯定回答：Yes,

否定回答：No,
you
