But
at
that
time,
it

open
the
door?
—Ok,
with
pleasure.

It
is
such
an
Interesting
story.
这真是如此有趣的一个故事。
such/so
such一般用作定语，修饰名词，放在所修饰词的前面。
so用来修饰形容词或副词。
e.g.
Do
you
like?such?weather
/
children?
I’m?so?glad
to
see
you.
She
can
draw?so?well.
当名词前有many,
much,
few或little等词修饰时，要用so而不用such。
e.g.
There
are?so?many
/
few
people
in
the
hall.
You
have?so?much
/
little
money
in
your
pocket.
“such
+a/an
+形容词+单数可数名词”相当于“so
+形容词+a/an+单数可数名词”，意思是“如此……的一个……”。
e.g.
She
is?such?a
lovely
girl.
=She
is?so?lovely
a
girl.
3.

a
point…
嗯，看来你说的确实有道理……
助动词do放在动词seem前面主要用来加强语气，“的确，确实”。在谓语动词前添加助动词do表示强调的用法常见于肯定句和祈使句中。
e.g.
He
did
come
but
soon
went
back.
他的确来过,
但很快就回去了。
have
a
point指“某人的说法或想法有道理”。
