解答
四个句型五个例句:
句型1.it was 时间点 when sth.happned.
句意:当某事发生时,时间是XXX.
例:It was 1997 when Hongkong returned to China.
主句:it was 时间点.it 是主语(不是形式主语,就是主句的主语),指代时间.(常见于:it is six o'clock now.It was ten o'clock when I got home.) when-从句为 时间状语从句,也可以放在主句前面.When sth.happened,it was XXX.
句型2.it was 时间段 before sth.happened.
意为:(在某件事情发生之后),另一件事情发生这前,这段时间是.
翻译1.过了.,就发生了另一件事.(主观认为时间较短)
翻译2.过了.,才发生另一件事.(主观认为时间较长)
例:It was 2 years before Macow returned to China too.过了两年澳门也回归中国了.
析:这句话前有例句子1为前提,是1997年之后,1999年之前这一段时间的长度(it was two years.)
误:It was two years after .,两年后,.也.了.
补充:before的前提是:前面发生过一件事,从这个时间开始,到另一件事情发生之前(before) 这一段的时间(时间段)是多长.
如果这个时间段长或不长,有两种不同的译法.
1.才过了多久就.了.
其中最常见的一个例句就是:It wasn't long before sth.happened.不久就.了.
2.过了很久才.
时间的长短是一相对的概念.
二年时间相对百年的殖民时代是短的,所以可以译作:才过了两年澳门也回归了.
但如有人考了两年才考出驾照.
He began to learn how to drive a car in 2005.
(It was 2005 when he began to learn how two drive a car.)
It was two years before he got the drive licence.就得译作:过了两年才领到驾照.
句型3.it is (=has been) 时间段 since sth.happened.
意为:自从某事发生以来(到现在为止)时间已经是多久了.
It is (= has been ) 14 years since Hongkong returned to China.香港回归中国已经有14年了.注:本来就是(现在完成时)has been 与since 从句连用.现代英语用is代has been了.
4.强调句型:It was in 1997 that Hongkong returned to China.香港是在1997年回归中国的.
注:before 句型的另一个时间,将来时态:
It will be N years before TW returns to China.( before TW is liberated.)
