at 1:00(dawn,midnight,noon)在一点钟(黎明、午夜、中午)
these are our chief tasks at the present stage.这些就是我们现阶段的主要任务。
2.on
1)表示具体日期。
they arrived in shanghai on may
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)the weekend?在周末---特指
at(on)weekends?在周末---泛指
over the weekend?在整个周末
during the weekend?在周末期间
(2)在圣诞节,应说"at christmas而不说"on christmas
2)在(刚……)的时候。
on reaching the city he called up his parents.一到城里他就给父母打了一个电话。
3.in
1)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,the 20th century)在一九八八年(十二月、二十世纪)
i returned to beijing in the middle of june.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。
during my military service(the trip)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:
the meeting will end in 30?minutes.(三十分钟后)会议三十分钟后结束。
can you finish it within 30?minutes?(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。 the job was done during a week.(wrong)
the job was done in a week.(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。
??after supper(8?o’clock,the war)晚饭(八点、战)后 比较:he will be back in two hours.他将在两个小时以后回来。
he returned to?his hometown after the war.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。 i stayed in london(for)two days on my way to new york.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。
since liberation(1980)自从解放(1980年)以来 they have been close friends since childhood.他们从小就是好朋友。 注:
(1)since the war是指"自从战争结束以来",若指"自从战争开始以来",须说"since the beginning of the war"。
(2)不要将since与after混淆。 比较:he has worked here since 1965.(指一段时间,强调时间段)自从1965年以来,他一直在这儿工作。 he began to work here after 1965.(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:
by noon,everybody had(will have)arrived there. by noon,everybody were(will be)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。
