these days 放在句中,必须用现在是吗 英语翻译句中的these days为什么放在那个位置 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 中 these 作什么句子成分? We are busy these days． In those days the workers had a hard time．We are busy these days．In those days the workers had a hard time．我在一篇文章中看见这2句话后面一句我明白需要加介词in我就是不明白为什么不能说 these days用什么时态? these days用什么时态? 'Everyone's losing money these days,'he 句中's读什么, 在i used to drink a lot of coffee but these days i prefer tea句中为什么用prefer原形呢新学员哟,请多多帮忙哟 It's rainy these days的同义句It's ( ) these days .
