Question

so that 和 to too 的详细用法和区别

Answer 1

"too…to"和
"so…that…"这两个句型容易混淆。
下面的句子可用两种方式表达
I
was
so
tired
that
I
couldn”t
move.
OR:
I
was
too
tired
to
move.
我累得不能动。
故必须留意并熟记so与that配搭，而too是与to配拾的。此外，必须注意以下三点
：
第一要注意的是，这两句型所含的不同意义。
"so…that"有"如此程度，以致……"而
"too…to"则有"如此程度以致下…
…"的意思。故此在
"too…to"后不须再有否定字眼，若不，就有双竽否定的情况出现。如：
(×)
The
box
is
too
small
not
to
hold
all
these
things.
(√)
The
box
s
too
small
to
hold
all
these
things.
其二要注意的是，虽然so与too都是用以表达形容词(Adjective)与副词(Adverb)和程度，但它们的结构却有别，请比较：
adj.
so
+
+
that
+
Clause
adv.
(从句)
adj.
too
+
+
to
+
Infinitive
adv.
(动词原形)
eg.
(1)
Helen
spoke
so
rapidly
that
we
could
not
clearly
understand
her.
Helen
spoke
too
rapidly
for
us
too
understand.
(2)
Mark
was
so
angry
that
he
could
not
speak.
Mark
was
too
angry
to
speak.
第三点，就是若
"so
…that…"
句型中的从句
(Sub-ordinate
clause)中的主语(Subject)与主句(Main
clause)中的不，改用
"too…to…"句型表达时，我们可以将for
+
Noun/Pronoun结构用在to
+
infinitive之前。请看下面的分析：
eg.
(1)
The
question
was
so
difficult
that
we
could
not
answer
it.
(从句中的Subject为
"we"
，而主句的Subject为
"The
question"。)
=
The
question
was
too
difficult
for
us
to
answer.
(注意
"it"不用写。)
(2)
Eddie
ran
so
quickly
that
we
could
not
catch
up
with
him.
(从句的Subject为
"we"而主句中的Subject为Eddie"。)
=
Eddie
ran
too
quickly
for
us
to
catch
up
(注意
"him"不用写。)
艾迪跑得太快，我们都赶不上他
