do
sth.,
enough
to
do
sth.
这三个句型可互换使用。
在so…that句型中，当主语和从句都是肯定式，且主、从句的主语指的是同一人时，可简化为enough
to
do
sth.结构。
e.g.
He
ran
so
fast
that
he
caught
up
with
us
quickly.
=
He
ran
fast
enough
to
catch

e.g.
The
problem
is
so
easy
that
she
can
work
it
out.
=The

enough
for
her
to

to
do

这三个句型可互换使用。
(3)
在so…that句型中，当主句和从句的主语一致，但主句是肯定式，从句是否
定式时，可简化成enough
to
do
sth.
或too…to
do
sth.结构。与enough

或too…to
do

to
do
sth.转换时，形容词或副词应变为与之相反的词，前面的动词为否定式。
如果主从句的主语不一致，须在to
do
sth.前加for
sb
作为不定式的逻辑主语。
e.g.
The
problem
is
so
difficult
that
we
can’t
work
it
out.
=The

too
difficult
for
us
to
work
out.
=The
problem
isn’t
easy
enough
for
us
to
work
out.
这道题太难了，我们解答不出来。
