it is 加序数词that加从句的用法

Question

如题所述

Answer 1

1、this
/
it
is
the
third
time
that
you
have
been
late
this
month
　　定语从句：that指代time，需要在从句中充当主语、宾语或表语，you
have
been
late
this
month是主系表结构，主语和表语都有，说明that不是句中的任何成分。如果把这个句子改为it
is
the
third
time
(that)
you
have
been
late
this
month
(for)，that成为介词for的宾语，就变成了定语从句。不过这种说法很拗口，没有人这样讲。
　　主语从句：it是先行主语（注意：this不能作先行主语），目的是平衡句子结构，也可以改回到that
you
have
been
late
this
month
is
the
third
time。显然that
you
have
been
late
this
month（你本月已经迟了）和the
third
time（第三次）不是同一个概念，也就是说“你迟了”是个事实，一个事实不能等于次数。
　　同位语从句：that
you
have
been
late
this
month是对the
third
time的内涵做出解释的，意思是这是第三次，换句话说就是你本月迟到这个事实的第三次。因此这里是同位语从句。
　　强调句：可以取消强调句式it
is
…
that，恢复成you
have
been
late
this
month
the
third
time，但是the
third
time不能直接作状语，必须加上介词for才能成立。
　　固定句型：固定句型也得符合语法，这是解释不清道理时常常使用的一种托词。
2、the
second
/
the
first
time
用作主语、宾语或表语时不用for，用作状语时前面必须加上介词for。for
the
first
time
/
for
the
second
time
和for
the
last
time
/
for
the
next
time
是同一系列的副词短语，last
time与next
time、another
time另外系列的副词短语，二者不能混淆。

Answer 2

it作为形式主语或宾语，that引导主语从句或宾语从句，有强调作用。
1.It was John that/who wore a white suit at the dance last night.（强调主语）
2.It was a white suit that John wore at the dance last night. (强调宾语）
3 It was in the library that he read three books yesterday.（强调地点状语）
4 It is at 5 o'clock that the train will arrive. (强调时间状语）

Answer 3

It is +the +序数词+time +that 从句，从句用现在完成时，译成这是第几次。。。。。。了
例：It's the first time that I have spoken English.这是我第一次说英语。本回答被网友采纳
