英语翻译
此说法对吗?
此说法对吗?
since作连词时后跟从句 此从句时态通常为：一般过去式 过去完成式 现在完成式
此时应注意一个句型：
1.It is/has been+时间段+since...自从…以来,过了…
eg:It is/has been three years since he finished the work.自从他完成这项工作已经三年了.
2.该句型中若since后跟延续性动词,要翻译成否定含义,即“没做某事已经多久了”.
eg:It has been three years since he worked here.他不在这工作已经三年了.
It has been three years since he smoked.他已经戒烟三年了.
3.若主句非It is…形式,则主句还可用过去完成时.
eg:He had been worrying since the letter arrived.自从接到那封信后他就一直焦虑不安.
