sinCE thEn sinCE 分别可以放在句首还是句尾

都可以

意思一样,用法小有差别 后者是多用在句首,逗号,之后再加完整句子 而前者在句首句中句尾都可以

since when 作为定语从句修饰1946. 如果是1946年发生的事,可以直接使用when 但句中给的事情是一直持续到现在的事情, 故用since when

您好,我来帮您回答: 1、since ever 翻译为自从,与现在完成时态或过去完成时态连用。 (这与ever since 略有不同,ever since+ 过去时的句子:◆ever since I was at school 。自从我上学以来.) ◆ He has lived there since ever.=Since ever,...

ever since 作为连词=since 完成时态---- ever since +主+动词简单过去式 例:I have known him ever since he was a child. 他从小我就认识他了。 这种用法同since 差不多,不过 ever since 比 since 用得少。 再如:We have lived in Shanghai...

since than用现完 from then on过去时,现完都可以 只要有since就用完成时

在英语小说中,ever since then 后面如果接瞬间动词比如start,强调的是那一瞬间的状态,那就用一般过去时;如果强调一种持续的状态就用 have/has been。 Ever since then, I started being addictive to alcholo. Ever since then, I've been v...

since then 从那时(到现在),一般用于现在完成时的句子 from then on 从那时开始,一般用于过去时的句子

一、一般现在时主要用于: 1 、表示经常性或习惯性动作。 e.g. It seldom snows here. 2 、表示现在的特征或状态。 e.g. He is always ready to help others. 3 、普遍真理。 e.g. Action speaks louder than words. 4 、剧情图片介绍,背景说明...

二者都是“从那以后”的意思,都可作连词,一般放在句中 since then 后接完成时,从那以后直到现在 after then后接过去时 如: I have known her since then. I kept in touch with her after that.
