时间名词前所用介词的速记歌年月周前要用in,日子前面却不行。遇到几号要用on,上午下午又是in。要说某日上下午,用on换in才能行。午夜黄昏须用at,黎明用它也不错。at也用在明分前,说“差”可要用上to,说“过”只可使用past,多说多练牢牢记,莫让岁月空蹉跎。下面就时间概念的介词用法做一简要介绍和比较。1.at表示时间概念的某一个点。(在某时刻、时间、阶段等)。at1:00(dawn,midnight,noon)在一点钟(黎明、午夜、中午)theseareourchieftasksatthepresentstage.这些就是我们现阶段的主要任务。2.on1)表示具体日期。theyarrivedinshanghaionmay2).他们在五月二十五日到达上海。注:(1)关于"在周末"的几种表示法:at(on)theweekend在周末---特指at(on)weekends在周末---泛指overtheweekend在整个周末duringtheweekend在周末期间(2)在圣诞节,应说"atchristmas而不说"onchristmas(2)在(刚……)的时候。onreachingthecityhecalleduphisparents.一到城里他就给父母打了一个电话。3.in1)表示"时段"、"时期",在多数情况下可以和dur-ing互换,前者强调对比,后者强调持续。in(during)1988(december,the20thcentury)在一九八八年(十二月、二十世纪)ireturnedtobeijinginthemiddleofjune.我是六月中回北京的。但如果表示"在某项活动的期间",则只能用during。duringmymilitaryservice(thetrip)在我服役期间(在旅行期间)2)表示以说话时间为基点的"(若干时间)以后",常用作将来时态谓语的时间状语。如这时要表示"(若干时间)内",常用within。比较:themeetingwillendin30minutes.(三十分钟后)会议三十分钟后结束。canyoufinishitwithin30minutes?(三十分钟内)你能在三十分钟之内完成这件事吗?但在过去时态中,in可用于表"在若干时间以内",这时不要误用during。thejobwasdoneduringaweek.(wrong)thejobwasdoneinaweek.(right)这工作在一星期内就完成了。4.after表示"在(某具体时间)以后",注意不要和in的2)意混淆。aftersupper(8o’clock,thewar)晚饭(八点、战)后比较:hewillbebackintwohours.他将在两个小时以后回来。\nhereturnedtohishometownafterthewar.战后他回到了故乡。5.for表示"(动作延续)若干时间",有时可省略。istayedinlondon(for)twodaysonmywaytonewyork.在去纽约的途中,我在伦敦呆了两天。6.since表示"自(某具体时间)以来",常用作完成时态谓语的时间状语。sinceliberation(1980)自从解放(1980年)以来theyhavebeenclosefriendssincechildhood.他们从小就是好朋友。注:(1)sincethewar是指"自从战争结束以来",若指"自从战争开始以来",须说"sincethebeginningofthewar"。(2)不要将since与after混淆。比较:hehasworkedheresince1965.(指一段时间,强调时间段)自从1965年以来,他一直在这儿工作。hebegantoworkhereafter1965.(指一点时间,强调时间点)从1965年以后,他开始在这儿工作。7.by表示"到……的时候",其谓语时态的用法:动作动词常用完成时态;状态动词(be)常用一般时态。比较:bynoon,everybodyhad(willhave)arrivedthere.bynoon,everybodywere(willbe)there.到中午的时候,大家都(将)到那儿了。以上探讨了介词表示时间概念时的用法和比较,上述介词除表示时间概念外还有其他的用法,英语学习者必须掌握其各种用法,才能灵活运用,提高自己的语言能力。
