ever在否定句中什么意思如 I hardly ever have time for concerts

ever在否定句中什么意思如 I hardly ever have time for concerts i ran faster than i had ever run before.这里的ever可以换成never吗?never用在否定句里所以不行吗?这里的ever是什么意思?我知道这句话的意思是：我从来没有跑得这么快过.但是 i had ever run before 有点难懂 I have ever been to Shanghai改成否定句 I have ever seen the film 变否定句 too在否定句中改为什么 请问频率副词在否定句中时候可以掷后?如I don't watch television usually will ever 等于 FOREVER?Only one that I'll ever love 我永远的唯一对吗?1L的你那几句中的WILL EVER都代表什么意思 我知道EVER是曾经 我就问问 WILL EVER 在英语中什么是否定问句,它跟否定句是一个意思吗? ever用于肯定句还是否定句 英语中否定句否定词放在什么位置 I hardly ever play game .I often play game .I never play game.分别看成肯定句还是否定句? I have ever been to HaiNan.(变为现在完成时的否定句) I have ever traveled on a plane.(改为否定句） 现在完成时中ever为什么有教辅说用在否定和疑问句中,我看到也有用在肯定句中的时候啊 or和and在否定句中的区别在疑问句和否定句中的区别很清楚.但是在肯定句中二者有什么区别?是否AND表示部分否定,OR表示全部否定?例如:I don't like fish and apples.I don't like fish or apples.我记得在哪 already,just,ever,yet,never具体放在句中什么位置 too either 用在什么句中?否定句 还是 肯定句 疑问句? I think he's very old.说出意思在改为否定句
