it was ...that...这个句型表达什么意思来着?看起来好像很眼熟,顺便给个简单例子.

It was in 2000 when he was in middle school 这个句子为什么不用强调句It was.that结构? It was not immediately obvious that water was to be fundamental to the devel这个是什么句.是不是从句 that's why it diversified into property and tourism 这个是不是被动句如果是 应该是it was diversified It was in the very school that was in the mountain that he spent his childhood.那位高手能解释一下这个句 Our classroom is very clean.Do you know who__cleaned it?A. was it that B. it was that C. was it who D.he was这要用什么语序,是强调句吗Do you know who it was that cleaned it？这个句子怎么分析 强调句,用It was, It is 怎么选择?强调句,用It was, It is 怎么选择? 是根据 主句的时态么? It was three years ago that I travelled last time. 这个句子应该是强调句吧? 强调句的话,It is / It was , 用 is ,或是 w 强调句it is（was) .that/who,其中it is（was)能不能写成it's/it was不能缩写么? It seemed that he was very happy的同义句 It seemed that was ill yesterday.（同义句）【急】 Sunny,it,and,was,that,warm,day连词成句 连词成句 sunny,it,and,was,that,warm,day sunny it and was that warm day连词成句 it was the color or the material which he was surprised at这个句子中的which能不能用that替换呢,感觉像是强调句啊, 强调句的that (who) 有时可以省略It was my brother (that / whom) you saw the other day.这个说是可以省略为什么啊？. was it all that It was you that That was it歌词 分析列个句子it was said that that that that that boy wrote is thatthank you分析这个that
