答:since 一、含义:conj. 因为;既然;自从。prep. 自从。adv. 此后。二、用法 since用作介词的意思是“从…以来,自从…之后”,其宾语常指过去的一个时间点,其含义通常指持续到说话时刻的动作或情况开始于什么时候。since之后常接名词、动名词作其宾语,since then意为“从那以后”。since引导时间...
答:应该是since then(从那时起), 不是 since than!根据"从那时起"的意思可以用现在完成时态,因为现在完成时是表示从过去某个时刻开始,动作一直延续到现在说话时。例如:I have studied English since then. 从那时起我就学习英语。(现在还在学。)
答:主句时态要根据从句选择,只有现在完成时、现在完成进行时或一般现在时,since引导的时间状语从句中用短暂性动词的过去式,主句用现在完成时或现在完成进行时。此时,整个句子可以直接按照字面意思翻译。例句:She has dealt with five guys since she divorced Tom.她和汤姆离婚后和五个男人交往过。
答:1. Since then, I have been reading books quite often.2. Ever since then, I have been reading books quite often.3. From then on, I often read (发音为red) books/ I have been reading books quite often.(1) 和 (2) 用现在完成进行时(因为强调从那时候一直到现在为止),(...
答:Since 用法小结 一.Since作为介词,后接某一确定的时间点,主句谓语动词是持续性动词,常与现在完成时态、现在完成进行时态或过去完成时态连用。例如:1、He left the village in 1982 and I haven’t seen him since then.1982年他离开这个村子,从那以后我再没见过他。2、She’s been working ...
答: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 ever since we came to China.(自从我们来到中国之后就住在上海.)then本身是个过去的时间点,since then表示从那个时间点到现在...

: then本身是个过去的时间点,since then表示从那个时间点到现在的情况,一般是现在完成时. I have not gone there since then. I have been there since then. It is 30 years since then. 所以99%的情况是不用过去时的,除非你写故事,故事里的时间发生在1980年,可以 It was 20 years since then. 这里的then当然是设定在1960年啦.这只是特殊情况
