◎分析：
adj+enough+to
do中
Enough是副词，修饰前面的形容词，表示程度，enough后面的动词不定式表示结果。因此，…enough
to
do…可以同too…to…或so…that…结构互相转换。
例如：
He
isn’t
old
enough
to
go
to
school.
=
He
is
too
young
to
go
to
school.
=
He
is
so
young
that
he
can’t
go
to
school.
他太小而不能上学。
★总结：1.not+adj.+enough+to
do
sth.
2.adj.+enough+not
to
do
sth=too...to
3.so...that.../such...that...
