初中英语之时间介词(in/on/at)
一、定义
时间介词是语言中用来表示时间关系的介词,它们在句子中起到连接时间状语和主要动词的作用。这类介词对于明确事件或动作发生的时间背景至关重要。
具体来说,时间介词可以表示动作或事件发生的具体时间点,也可以表示较长的时间段
此外,时间介词还可以用于表示特定的日期或时间。,
综上所述,时间介词是语言中不可或缺的一部分,它们帮助我们准确地描述和理解事件或动作发生的时间背景。通过学习和掌握这些介词的用法,我们可以更有效地进行沟通和表达。
二、考点分类
a) “at”,通常用于表示一天中的某个具体时间点,有的时候也表示在某一个节假日,如果把一段时间看成一个时刻,也可以用at。如“at noon”(在中午),“at 8 o'clock”(在8点钟)。
b) “in”常用于表示较长的时间段,如年份、月份、季节等,如“in 2023”(在2023年),“in spring”(在春季),in July (在七月份)等。
“during”也用于表示某个时间段内,强调时间的持续性和正在进行的状态,如“during the summer”(在夏天期间)。
c) “on”常用于表示具体的日期或星期几,以及该天的上午、下午或晚上,如“on Monday”(在星期一)或“on the morning of May 1st”(在5月1日早上)。
此外,还有其他时间介词如“before”、“after”、“since”、“until”等,它们用于表示时间的先后顺序和起始结束点,丰富了时间表达的多样性和精确性。这些介词在使用时需要根据具体语境选择合适的用法。
三、特殊用法
· “这” “那” “上” “下” “每个”前 in/on/at 都不填
如:this week这一周, that weekend那个周末, last Friday上周五, next month下个月, every year每一年
· in+世纪/时代/朝代/一段时间
如: in the 21st century 在21世纪
in the 1990s 在20世纪90年代
in 8 years 在8年后 用“How soon”提问
in the Tang Dynasty 在唐朝
· at +圣诞/the age of+数字等
如: at Christmas 在圣诞
at the age of ten 在10 岁时
at the beginning/end of… 在… 的开始/结束
注意:节日前一般加on/at 区别如下:
· at 可以理解为在这个节日附近的时间段
如:at Christmas 在圣诞节期间,包括平安夜和圣诞节那一天
at Easter 在复活节期间
at Spring Festival 在春节期间
· on可以理解为就是在这个具体的一天
如:on Christmas/Mother’s/Children’s day
四、应试技巧
1. 口诀:in 年in 月 in季节,泛指一天早午晚。
on日on号on星期,具体某天早午晚。
at要加时间点,黎明正午和夜里。
时间词前有修饰,统统把on放在前。
这那上下每个前,in on at 都不填。
2. 24小时法 步骤
1) 首先判断是否是三长两短:in the morning/afternoon/evening at noon/night
2) 不是三长两短:in+>24小时 on +≤24小时 at+时间点
