During

during的涵义是“当之际”,它既可指某个动作在某个时期里连续不断地进行,也可以指某个动作在这段时期里的某个时间发生.本题They __ nothing to heip the homeless girl during the last school year.答案是have done .是during和现在完成

1.during和in表示发生在整个时间段内的某个时候,跟特定期间的词,即时间长度明确,起止时间确定:during/in the afternoon;during the spring=in spring(注意冠词的用法).2.during和for都可跟时间长度的词,但动作不延续,有间断的用

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during.例如:He came to see me during my absence.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 visited many cities during their stay in China.Her grandpa was killed in the war.

during + 时间 表示在某段时间里常用作现在完成时态的时间状语 !11 现在完成时态常接的时间状语 : 如so far,by now,up to(till)now,for,since, in the past few…,during the last few…等. We have planted more than two thousand trees by now

都可以表示指时间,但是有区别.during是指在一段时间内(已发生),例如 i went to America during the holiday.in 是指未来的时间,例如老板将在两天内回来:the boss will come back in two days.

during + 时间表示在某段时间里.时态主要取决于during后面的时间.主要有下面几种1.She engaged in writing during the second world war“她在二战期间从事写作.”这时

during是介词,一般表示“在.…期间”!如:当所指的时间起止分明时用介词during;如果一段时间不明确则用介词for.具体摘抄如下:1. 表示“在……期间”,是介词,不要将其误用作连词.如: 他在巴黎期间,与他的朋友住在一起.

介词 :在…的时候; 在…期间,当…之时; 其间 你的采纳我的动力 很高兴能够帮助你

1)during和in都可以表示某事发生在某段特定的时间内.例如: ①They'll be on holiday during/in August. 他们将在八月份度假. ②She suddenly woke up during/in the night. 她夜间突然醒来. 2)当强调整段时间时,多用during.例如: ③The
