Question

It's time to ___ _____

Answer 1

这其实是一个句型，只不过后面要跟不同的东西。
it's
time
to跟的是不定式（to
do）。
也就是说，要跟一个动词，意思是“到做某事的时候了”。如：
it's
time
to
go
home.
it's
time
to
tell
him
the
truth.
it's
time
for
跟的是名词。也就是说，不能跟动词。如：
it's
time
for
lunch.
(没必要说it's
time
to
have
lunch)
it's
time
for
class.
(没必要说it's
time
to
begin
the
class.)
总之，句子能短则短。能省一个词就省一个词。用一个名词就解决的问题，就不用to
加动词了。
