ever since和since有什么区别,怎么用
ever since和since的区别为:指代不同、用法不同、侧重点不同。
一、指代不同
1、ever since:打…以后。
2、since:从…以来。
二、用法不同
1、ever since:since用作连词作“自从…以来〔以后或,现在〕”解时,引导时间状语从句,在主句是现在完成时的情况下,如果since从句中谓语动词用一般过去时,则表示动作或状态的完成,计时的起点是动作或状态完成的那一时刻。
2、since: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,其含意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”。
三、侧重点不同
1、ever since:侧重于指从某个时间后一直持续。
2、since:侧重于只是陈述从某时以后。
ever since后面可以不加任何东西,也可以加名词或者加从句.
例如:
I have never lied to him ever since.自那以后,我再也没对爸爸撒过谎.
Ever since 2000, he has lived there.自从2000年,他就住在那儿 .
Ever since he was 6,he has lived there.自从他6岁,他就住在那儿.
since ever 是副词,只能孤零零的放在句末,或者句首.
例如:
He has lived there since ever.=Since ever,he has lived there.从那以后,他就住在那儿.
ever since,adc,从那时到现在;sincead.自那时以后,prep.自…以后,自…以来,conj.既然,自…以后,自…以来。
ever since 作为连词等于since 完成时态---- ever since +主+动词简单过去式。
ever since 用法,一般就是可用在句首,自从的意思. 主句用现在完成时,从句用一般过去时;
since的用法主要有两点:一是表示“自从……以来”,二是表示“既然”之意。但如果只了解词的含义,而不了解其用法,在使用时就会造成错误。
1、前者无需考虑动词的延续性还是短暂性,都作“自从,或从…起”讲:
I have got a few opportunities to catch up with my classmates ever since I was ill.
2、后者则需分以下三种情况加以区别:
2.1 从句谓语动词为 be,且表成长某阶段或年龄时,则相当于 ever since:
I have lived here (ever) since I was a child.
2.2 从句谓语动词为延续动词,且为现在完成时,则无需介怀:
She has never come to see me since I have lived in the city.
2.3 从句谓语动词为延续动词,且时态是过去一般时,需在该动作结束后才能开始:
I have made great progress since I was ill. (可不是自从生病了就进步了哈)
3、最经典的语法例句,常见于小说:
It is twenty years since I lived here.
