#英语学习#IN, ON和AT有什么区别？

#English Study# What is the difference: IN, ON and AT. When English speakers talk about time and place, there are three prepositions that often come up: in, on, and at. These three words do follow some basic rules. Let's begin with location, or place. We use “in” with cities, countries, neighborhoods, and places with a clear boundary or dividing line. For more specific places, like certain streets, we use the preposition “on”.  When we are talking about an exact location or intersections, we must use “at.”

Let’s look at how we talk about time. We use “in” to refer to a general, longer period of time, such as months, years, decades, or centuries.  Getting more specific, we use “on” to talk about particular days, dates, and holidays. Finally, we can add the time, and use “at.” For example:“Her wedding is on Saturday, September 24 at 1:00 pm.”

Above is a simple chart to help understand the prepositions IN, ON, AT when used for time and location. #AmericanEnglish#

#英语学习# IN, ON和AT有什么区别？

当我们用英语说时间和地点时，有三个介词经常出现：in、on和at。这三个词的使用的确有一些基本规则。我们先讲讲谈论位置或地方的介词。我们在城市、国家、社区和有明确边界或分界线的地方的前面使用介词 "In"。对于更具体的地方，如某些街道，我们用介词 "On"。而在说一个确切的位置或交叉点时，我们要用 "At"。再来看看如何用这三个介词来说时间。我们用 "In "来指代一般的、较长的时间段，如月、年、数十年或几个世纪，用 "On"来说特定的日子、日期和假期。最后，对于特定时间，我们可以用 "At"。例如："Her wedding is on Saturday, September 24 at 1:00 pm. （她的婚礼是在9月24日星期六下午1点。）" 上图是一个简单的图表，帮助大家理解介词IN、ON、AT在用于时间和地点时的用法。#AmericanEnglish#
