初中英语时间介词的用法小结

初中英语时间介词的用法小结 表示时间的介词,在英语介词中占着相当重要的位置。在初中阶段英语教学过程中,已出现了许多用来表示时 间的介词。其中有:at on in during for to till un til after by before等。本文着重谈一谈这些介词在 表示时间的用法及它们之间的同异之处。 1.at on in a)at用来表示时间时,通常指时间的某一点。例如:at five o’clock atnoon atmidnight b)on用来表示某一段时间,特指某天或某天的上午下午或晚上。例如:on Sunday,on October,on Satu rday morning. c)in也可用来表示一段时间,但多指长于一天或不到一天的时间段。例如:inJanuary,insummer, in198 8, in the morning ,in the evening. 2.in与during a)during用来表示一段时间,其意义大致相当于in的用法。一般来说,凡是能用in的地方,也可以用d uring.例如:He came to see me during my abse nce.Don’t go to see his wife in his absence. B)during与in的区别在于during强调时间的延续性,而in则只是一般指某一时间。试比较:They vis ited many cities during their stay in China.Her grandpa was killed in the war. 3.in for during a)“in+时间”与“for+时间”都可表示一段时间,但“for+时间”表示“有多久”,而“in+时间” 则表示“在何时”。例如:We worked there for the winter.They worked there in winter. 以上两例中,in winter强调“在冬季”,不一定包括整个冬季时间,而for the winter则强调“整个冬天”。 b)for用来表示一般时间,常跟具体的时间段。例如 for a few days for 3 weeks for five months等 4.since与after since与after 都可以用来引导表示从过去某一点开始的时间段词组。它们的不同之处在于: a)since引导的词组所表示的时间一直延续到说话时为止,因而要与现在完成时连用。例如:He has bee n there twice since 1982.I have done nothing since six o’clock. b)after引导的词组所表示的时间是纯系过去,并不延续到说话时,因此要和一般过去时连用。例如:He went home after school. 5.till until与to a)介词till/until常用于“from.……till/until”结构中,表示“一个动作的终结”。介词to常用在“from.……to”的结构中,用来表示“一个阶段的终结”。两者在这种结构中意义十分接近。例如:The Am ericans stayed here from June to September.He studies from morning till/until night everyday.

time用法知多少

一. 句型 1. It’s time for sth . 或It’s time ( for sb . ) to do sth . 意为:该是……的时候了。例如: It’s time for dinner . 该是吃晚餐的时候了。 It’s time for children to go to bed . 是小孩睡觉的时候了。 2. It’s ( high ) time ( that ) sb . did sth . 意为:该是……的时候了。该句型中的that 从句需要用虚拟语气,谓语动词常用过去式。例如:It’s high time that we stated . 我们该出发了。 It’s time that we devoted ourselves to our country . 该是我们报效祖国的时候啦。 3. This is the time when sb . should do sth . 或The time has come when sb . should do sth . 这两个句型也用来表示“该是……的时候了”,when 引导的定语从句用陈述语气或“sho uld + 动词原形”的形式。例如:This is the time when you should get u p .是你该起床的时候了。 The time has come when we must part from each other .该是我们必须道别的时候了。 提示:以上几个句型都可以表示“该是……的时候了”,形式虽然不同,却可以互相换用。如“该上学了”,可用下面几种句型来表达: It’s time for school . It’s time for us to go to sch ool . It’s ( high ) time that we went to school . This is the time when we should go to school .
