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引导的状语从句【释义】by the time在……时候:表示某个事件发生时的时间点,通常用来描述在某个特定时间之前或之后发生的事情。

“by+时间”的时态“by+时间”意为“不迟于(=not later than)”;“一到(=as soon as)”;“当某时候到了[=when (the time indicated) comes]”;“到…时为止”等。
时间上有过去、现在和将来之别。
主动词本身有动作与状态之分,其时态可为一般式、完成式、进行式或完成进行式。
现分述如下:1.“by+时间”与动作性强的动词连用时,主句多用于完成式。
by 后的时间可指现在、过去或将来时间点。
如: By the time he was fourteen years old, he had learned maths all by himself. 到14岁的时候,他就已经自学了数学[SB 2B p.2]。
I shall have finished it by the time you come back.你回来以前我就把它做完了[1]。
By the end of the match, they had kicked two goals and we had kicked four. [JB p91] 比赛结束时,他们踢进了2分我们踢了4分。
They must have finished their work by this time.他们现在一定已经完成工作了[2]。
但是,上述情况中当时间为将来时,主句动作发生在从句动作之后时,主句动词可用一般时态。
如:If you're not better by then, I'll take you to see the doctor. [JB3 p.85] 如果到那时还不好些,我就带你去看病。
Can you finish this by tomorrow? 在明天以前你能做完这件事吗[1]?间或有用进行式的。
如:By the end of the first week the head of the department was saying very nice things ab out me. 第一周末时系主任给我多多美言了几句 [3]。
bythetimeof的用法
"by the time of"的用法是指在某个特定的时间点之前。
它常常用来描述两个事件之间的时间关系或某个事件在特定时间点之前的状态。
以下是一些例句:
1. By the time of his retirement, he had worked for the company for 30 years.
(在他退休的时候,他在这家公司已经工作了30年。
)
2. By the time of the meeting, I had already finished my presentation. (在会议开始之前,我已经完成了我的演讲。

(到婚礼的时候,新娘已经选好了她的婚纱。

需要注意的是,"by the time of"强调的是某一特定时间点之前的事情发生或完成。
by the time引导的时间状语从句时态规则“Bythetime”是英语中的一个常见短语,用来表示某个动作或事件发生时,另一个动作或事件已经完成或正在进行。
在句子中,它常常用来引导时间状语从句,表示时间先后顺序。
在使用“by the time”引导的时间状语从句时,我们需要注意时态的使用规则。
具体来说,有以下几点:1. 如果主句是一般现在时,则从句需要使用一般过去时。
例如:- By the time I get home, my mom has already cooked dinner. (主句为一般现在时,从句使用一般过去时)2. 如果主句是一般过去时,则从句需要使用过去完成时。
例如:- By the time I arrived at the party, everyone had already left. (主句为一般过去时,从句使用过去完成时)3. 如果主句是将来时,则从句需要使用将来完成时。
例如:- By the time you come back, I will have finished my work. (主句为将来时,从句使用将来完成时)需要注意的是,如果从句中有表示持续性动作的动词,我们需要使用完成进行时。
例如:- By the time I finish school, I will have been studyingfor 12 years. (从句中的动词“studying”表示持续性动作,因此使用完成进行时)总之,使用“by the time”引导的时间状语从句时,我们需要根据主句的时态来确定从句的时态。
在实际运用中,需要注意不同时态之间的转换和正确使用。
