by the time的用法详解
"By the Time"用法详解
哎哟喂，说起这个“By the Time”啊，在咱们四川话里头，没得直接对应的词儿，但咱可以拐个弯儿，用点儿地道的说法来给你摆一摆它的意思。
你想啊，“By the Time”就是说到某个时间为止，那时候已经怎么样了。
咱们四川人爱说“等到啥子啥子的时候”，味道就差不离了。
比如说，“By the time I got home,dinner was already cold.”换成四川话就是：“等我晃到家的时候，饭都冷得跟冰疙瘩似的了。
”看嘛，多形象，多接地气！
再举个例子，“By the time the movie ended,everyone was crying.”换成咱们这儿的说法：“等电影放完的时候，全场人哭得稀里哗啦的。
”这下子，是不是感觉画面感满满，还带了那么点儿情感色彩？
用四川话讲这些，不光是换了种说法，更重要的是能更生动地表达出那种情境和氛围。
就像你走在成都的街头巷尾，听到那些家长里短，感觉每个字都落在心上，暖洋洋的，又或者是麻辣辣的，让人回味无穷。
所以，下次遇到“By the Time”，不妨试着用咱们四川话的方式去理解，去表达，说不定能碰撞出不一样的火花呢！。

by the time用法
by the time用法
by the time意为到……时候（为止）"，是一个介词短语，在句中经常起连词作用，引导时间状语从句。
它的主要用法如下：1，如果从句中的谓语动词是一般过去时，那么主句中的谓语动词通常用过去完成时，表示“截止到从句动作发生时，主句动作已经完成，即过去的过去"。
2，如果从句中的谓语动词为一般现在时或现在完成时（表示将来），那么主句中的谓语动词常为将来完成时，表示“截止到将来某一时间为止，主句动作将已经完成"。
3，如果主句动作不强调已经完成，只是说明某个时候的状况，（主句是be的系表形式或者是表示像know，find，believe等表示认知的持续性动词，则往往用一般时态，不用完成时态。
）此时主句不用完成时，而应根据实际需要选用适当的时态，此时by the time 相当于when。
扩展资料：
注意时态的变化：在一般情况下，如果从句的谓语动词用一般过去时，主句的谓语动词用过去完成时；如果从句的谓语动词用一般现在时，主句的谓语动词用将来完成时。
例如：
By the time you came back, I had finished this book.
到你回来时，我已经写完这本书了。
By the time you come here tomorrow, I will have finished this work.
你明天来这儿的时候，我将已经完成此工作了。
