这个知识点也算是考点了
既要死记
又要活用

加油噢
一、作主语
⒈不定式作主语
动词不定式作主语时，句子的谓语动词常用单数，其位置有以下两种：
(1)把不定式置于句首。如：
To
get
there
by
bike
will
take
us
half
an
hour.
(2)用it作形式主语，把真正的主语不定式置于句后，常用于下列句式中。如：
①It＋be＋名词＋to
do
It's
our
ty
to
take
good
care
of
the
old.
②It
takes
sb+some
time+to
do
How
long
did
it
take
you
to
finish
the
work?
③It＋be＋形容词＋for
sb＋to
do
It
is
difficult
for
us
to
finish
writing
the
compositionin
a
quarter
of
an
hour.
④It＋be＋形容词＋of
sb＋to
do
It
is
stupid
of
you
to
write
down
everything
the
teachersays.
⑤It
seems(appears)＋形容词＋to
do
It
seemed
impossible
to
save
money.
在句型③中，常用表示客观情况的形容词，如：difficult,easy,hard,important,impossible,necessary
等；在句型④中，常用careless,clever,good,foolish,honest,kind,lazy,nice,right,silly,stupid,wise等
表示赞扬或批评的词。在不定式前的sb，可看作其逻辑主语。这一句式有时相当于Sb
is＋形容词＋to
do句式
，如：It'skind
of
you
to
help
me
with
my
English.=You
are
kind
to
helpme
with
my
English.
⒉动名词作主语
Learning
without
practice
is
no
good.
动名词作主语时，也常用It句式。如：
①It's
+no
good(no
use,fun,a
pleasure,a
waste
of
time)+doing…
It's
no
good
reading
in
dim
light.
It's
no
use
sitting
here
waiting.
②It's＋形容词＋doing
It's
dangerous
swimming
in
the
sea
in
windy
days.
这样用的形容词有expensive,nice,tiring等，但important,necessary则不适用于这种结构，应用不定式
代替，如：It'simportant
for
you
to
keep
fit.
③There
is
no+doing
There
is
no
saying
what
will
happen
next.
在这一结构中，动名词后常带宾语，相当于"It's
impossible
to…"结构。
