英语常考热点句式:it is +时间 + since (before, when)

 

请注意以下三个句式的区别和意思上的差异(其中的 is 根据情况可以有其他时态形式):

It is + 时间段 + since… 的意思是自从……以来有一段时间了

It is + 时间点 + when… 的意思是……的时候时间是……”

It is + 时间段 + before… 的意思是……之前有一段时间

请看以下用例:

It’s ten years since they got married. 他们结婚到现在已经十年了。

It was past one o’clock when he came in. 他回来时已经一点多了。

It won’t be long before they understand each other. 过不了多久他们就会互相了解的。

有时翻译可以比较灵活:

It’s a long time since I met you last. 好久不见了。(直译:自上次见到你以来有很长一段时间了。)

It’s about three years since I last played basketball. 我差不多有三年没有打篮球了。(直译:自从我上次打篮球以来已差不多有三年了。)
