in those days有没有在那些天的意思

in those days有没有在那些天的意思 In Those Days有没有以前的意思 在三年前的英语怎么说网上说是three years ago,我想问为什么不是in three years ago还有在那些天的英语为什么不是in those days,为什么不是in those days 这些天是these days,那些天却是in those days,为什么?一个加in一个不加? in those days还是on those days 为什么“在那些日子”是in those days,而这些日子是these days,不是in these daysThey are busy preparing for the maths test these days.不能写成in these days吗?In those days,the could not go to school.不能写成those days吗 in加一段时间用在将来时,那为什么in those days（在那些日子里）用在过去式.给我弄糊涂了?in加段时间到底是用在将来时还是过去式. He (be)_rich in those days答案为什么是was,有these days的地方用于现在完成时,本句中有those days,为什么用于一般过去时 10.We shall never forget the days ___ we worked together.A.that B.in which C.on which D.whichz这道题选B,为什么不选C?在那些天 不是on those days么7.I will never forget the day____ we studied together.A.at which B.on that C.at that D.on There were few schools in those days. In Those Days可以繁殖以前吗 英语中状语的位置举一个例子：In these days,I get up early.还是These days,I get up early.也就是有没有In,为什么.那要是These days放在句尾呢,有没有In? these days 和those days 分别用在什么时态? these days与those days有什么区别 the first nine days in this year有没有语法错误? She often came to help us in those days. There were no-------- books in those days.(print) in those days应用什么时态中请附加例句
