It+ be+时间+从句&这类句型用法小结
&&&&&&&&&&&&&& 江西省泰和县第二中学& 周莲花
&一、 句型归纳:
&1.It is/has been + 时间段 + since + 一般过去时
例1:It is/has been 10 years since he came here.这类句型可转化为:
=Ten years has passed since he came here.
这一句型可扩展为:It was+时间段+since(从句用过去完成时)
例2:It was years since he had arrived in China.(过去时+since+过去完成时)
需要注意的是since从句的谓语动词一般是非延续性动词,但有时也可用延续性动词或表示状态的词,此时需要注意句子的翻译:
例3:It is three years since she came to our class.她来我们班已经有三年了。(从动作开始时算起)
It is three years since she was in our class.她离开我们班已经有三年了。(从动作结束时算起)
2.It + was + 时间点 + when clause(从句谓语用一般过去时)
It+ will be+时间点+when clause(从句谓语用一般现在时表将来)
例1:It was already evening when he came back.当他回家时已经8点了。
例2:It will be midday when they get home.当他们到家时将是中午。&&&&&&&&&&&&&&&&&& 3. It + will(not) be + 时间段 + before +现在时
It+ was(not)+时间段+before+过去时
例1:It will be another year before he comes here.
例2:It was some time ______we realized the truth.(2005山东24)
A. when  B. until  C.& since  D.before
正确答案:D. 过了一段时间后我们才了解了真相。
该句型中before前常用时间段,表示&&之后才&&&在&之前就&&;有时before前也可以用时间点,此时突出表示动作的变化。试比较:
例3:It was evening before we reached the little town of Tailstocks.
当我们到达Tailstocks时已经黑了。(到达前天还没有黑)
4.It/This is + the + 序数词 + 时间 +(that)定语从句(从句用完成时)&& &&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&例1:It is the first time (that) I have & been here.(定语从句)
该句型可扩展为:It was+序数词+时间+(that)定语从句(从句用过去完成时)
例2:It was the second time he had been out with her alone.
例3:It&s the second time you ________late this week.
A. arrive & B. arrived   C. have arrived  &&&&&&& D. had arrive
正确答案:C.
5.It is + (high)time + that + did(虚拟语气)
例1:It is (high) time (that) we stopped & pollution.
其中that引导的从句中也可用should +V(原形), should不可省。
例2:It is (high) time (that) you& came/should come here.
写作中表示建议时也常可用这类句型。
例3:It&s high time we took measures to solve this problem
注意应将以上5种句型与强调时间的强调句型的区别:
注意应将以上5种句型与强调时间的强调句型的区别:
6.It be + 时间(被强调部分) + that从句
例1:It was at 6 o&clock that we heard the noise.
例2:It was 3 years ago that he joined the army.
最简单的判断方法是:当表示时间的词前有介词或者后有副词时,一定是强调结构,必用that。
试比较下面句式与强调句的不同之处:
⑴It was already ten o&clock when he arrived.
⑵It is ten years since I met you last.
⑶It was quite some time before he found the elephant at all.
以上几句中时间前无介词后没副词故不是强调句型。

二、巩固练习:注意连词和时态这两方面。

4.&&&It won&t be a minute _____the supper is ready.

6.&&&It was dark ______they came out of the hall.
7.&& It is 10 years _______I ran across him last.

14.&It was in March _____we came back to school.
