to do 和 doing作主语的区别

Question

如题所述

Answer 1

　　to
do和
doing
作主语的区别
　　1）一般来说，表示比较抽象的行为动作时多用动名词doing；表示比较具体的某次行为动作时多用不定式to
do。如：
　　No
smoking
is
permitted
here.
　　It
is
not
very
good
for
you
to
smoke
so
much.
Reading
more
is
necessary.
　　It
is
quite
necessary
to
read
it
again.
　　2）在许多情况下，两者可以互换，意义上没有太大的差别。如：
Seeing
him
happy
made
me
happy
too.
It
made
me
happy
to
see
him
happy.
　　It
is
useless
learning
something
without
practising
it.
It
is
useless
to
learn
something
without
practising
it.
　　3）在
there
is
no
...
句型中的主语只能用动名词doing，并且不能带逻辑主语。
　　4）doing
作主语时强调的是做那件事的状态，而to
do
作主语时主要表示一般现在时或者是将来时的事情。
