By和Before的用法区别
今天档源英语学习网小编给大家说一下by与before在表达时间方面的区别吧。
by表示不迟于某一点时间(可能是现在,也可能是过去),包括了那一点。例如:
You'd better come back by 8'o clock.
He had finished the work by ten o'clock this morning.到今天上午十点钟, 他已完成了这项工作。[1]work,this,相关知识点
By与before都可以做介词与副词,但是Before还可以做连词,当两者都表示在----之前这意思时候,By的词性只能是介词,而Before三种词性都可以用来表达。简单点说,By在表示在--之前,只能表示在某个时间点之前,而且已经非常接近这个时间点,而Before离这个时间点,还很长。[2]副词,连词,相关知识点
China plans to expand its high-speed railway network to 50,000 km by 2020, to cover almost all large and medium-sized cities.
by 2020 是到2020年,刚好2020年
before2020 是在2020年以前
以上两种表示法,仔细分析意思完全不一样的,不能互换,否则计划会变得完全不一样。
before与by都可表示“在……之前”,但by含有“不迟于……”、“到……为止”的意思。如果by后是将来的时间,则与将来时连用,若by后是过去的时间,则与过去完成时连用。
before 与 by 都可表示“在……之前”,但by含有“不迟于……”、“到……为止”的意思。如果by后是将来的时间,则与将来时连用,若by后是过去的时间,则与过去完成时连用。[3]before单词记忆法

before monday一般用于将来时或过去完成时,例如:I must finish my homework before monday.[5]homework,finish,相关知识点

受中文的影响,这个介词常常被误用。当你要表达在一段时间内某个动作可以完成时,一定要用in,而不能用after,因为after是指在某一时间之后。例如:This work will be done in two days. 即表明在两天内这一工作一定会做完。而如用了after,即表示在两天之后,完成的时间是不确定的。[误] My father will be back after查看详情>>

immediately用作副词和连词immediately用作副词和连词1. 用作副词,主要表示“立即”“马上”。如:I answered his letter immediately. 我马上给他回了信。有时表示在时间或空间方面很接近或直接,此时通常用于形容词、副词、介词短语等之前。如:He lives immediately next to us. 他就住在我们隔壁。I l查看详情>>
