by the time 与by the end of time 都是到 为止 什么区别

By the time1.表示将来的时间.主句用将来完成基旁时,而从句用一般现在时来表示将来的动作.如:I will have finishied the work by the time my father comes back.2.表示过去的时间.主句用过去完成时,而从句用一般过去时.如：He had built a lab for himself by the time he was 12 years old. by the end of“到.末”,多指时间,常用于完成时态,也用于将来时态.By the end of last month they had planted 10,000 trees.如：到上个月月底他们已经栽了一万棵树. be the end of 与 by the time后面跟什么时态?be the end of 是……致死的原因,后面常接名词或从句搏嫌橡,时态要看情景来决定的by the time 表示等到……的时候,这个时态也要看说的是什么,常用过去式eg:Bythetimethe plane reached them it was moving at full takeoff。 by the time和by that time什么区别by the time和by that time均与完成时相连用，可能是现在完成时，过去完成时或将来完成时。区别如下：by the time具有从属连接词的特征，称为短语连接词，后面可以接一个完整的句子，是时间状语从句，这个时间状语从句的主句用完成时。如：By the time he's twenty, he'll know everyone worth knowing in Washington.到20岁时，他就会认识华盛顿所有值得认识的人。The storms had abated by the time they rounded Cape Horn.他们绕过合恩角时，暴风雨已经减弱。By the time we had to sell, prices had fallen catastrophically.等到我们不得不出手的时候，价格已经崩盘了。She had slipped into a coma by the time she reached hospital.到医院时，她已陷入昏迷。by that time是单独作为时间状语使用的，后面不能接句子。如：By that time the steel output will have greatly increased.到那会儿钢的产量将大大增加。By that time her enthusiasm had cooled.到那时她的热情已经冷却了下来。The enemy's arsenal had been uncovered by that time.敌人的军火库那者誉时已暴露了。By that time they should have fetched up in Qingdao.到那时候他们应该已经抵达青岛了。
