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。

by加时间的用法
by加时间的用法1. by+时间的基本用法by是一个常见的介词，表示“通过某种方式”。
“by+时间”常用来表达在某个时间之前完成某个动作或事件。
举个例子，我们可以说：- I'll finish my work by 6 pm. （我会在下午6点之前完成工作。
）- Please return the book by Friday. （请在周五之前归还这本书。
）这两句话中的by+时间表明了动作的截止时间。
第一句话中是下午6点，第二句话中是周五。
如果我们没能在规定的时间之前完成需要做的事情，就会产生不好的后果。
例如，如果你没能在周五之前归还书籍，你可能会被罚款或者失去借书的权利。
2. by做时间段除了表示截止时间，by+时间还可以表示一个时间段，这时候我们要用复数形式。
举个例子：- I'll be away from home by two weeks. （我会离家出走两周。
）这句话中的by two weeks不是表示在两周之前完成某个动作，而是表示这个时间段内我会离家出走。
类似地，我们还可以说：- She'll be back by two months. （她会在两个月之内回来。
）- They'll finish the project by three years. （他们会在三年内完成这个项目。
）在上面的三个例子中，by+复数时间表示一个时间段，补充说明了动作或事件的持续时间。
3. by与by the timeby the time是by+时间的另一种表达方式，常用来表示到某个时间为止某个动作已经完成了。
举个例子：- By the time you arrive, we'll have finished dinner.（当你到达的时候，我们会已经吃过晚餐了。
）这句话中的by the time you arrive表示到达之前我们已经完成了晚餐。
类似地，我们还可以说：- By the time we get there, the concert will have started. （我们到达那里的时候，音乐会已经开始了。

By the time 用法详解•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”。
例如：By the time he returned home，the rain had stopped.•By the time I got to the station，the train had already gone。
• 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”。
By the time you get back，I shall have finished the work.•By the time I graduate next year, I will have lived here for 5 years.•By the time of next term , we will have learned 3000 words.• 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。
例如：•He was out of breath by the time he reached the top.By the time the bus came，so many people were waiting that it was a free fight to get on it.公共汽车来的时候，等车的人很多，成了一场挤车的混战。
•By the time he went abroad, he was fourteen.出国那年他14岁。
•By the time the war was over , death and suffering were to be seen everywhere.•在战争结束的时候，到处可见死亡和饥饿。
这里没有“死亡和饥饿”已经完成的意思，只是描述当时这个时间点的状况。
所以用过去时。
