in加一段时间 用how long还是how soon提问

in加一段时间 用how long还是how soon提问 How soon和How long 的区别?例句：——are you staying in Beijing?For about two weeks.How soon 有人解释说是对一段时间提问?那这题到底是How long 还是How soon呢? how long 加动词原形还是其他? 对 in a second 提问用什么?是用 how long 还是how fast 还是 how soon 还是什么？ how long完成时how long不是问一段时间的吗?为什么可以用How long did you stay? 提问 in a couple of days用什么是用How often 还是How long how long aog did he begin his diet?的回答是for+ 一段时间如for a week还是不要for是how long ago有ago还是用for吗？ in加一段时间用现在完成时么 how long have they 还是用them how long have they 还是用them in twenty minutes'time用什么提问如题.是用when还是how long呢 为什么how long提问,答语前面要加for—How long have you lived in China?—For about three years.为什么答语前面用for啊? Mary has lived in Shanghai (for over two years)对括号内提问用how soon还是how long 我知道for加一段时间时态大部分用完成时,如果是延续性动词用过去式那么延续性动词是只能用过去式么?比如：please tell me how long you stayed in paris可不可以用please have或had stayed in paris 对 several hours 提问用how soon 还是how long? how long will you stay there?()four days.填for还是in?表将来不是用in吗 It goes from Shanghai Station to Pudong Airport in eight minutes.对in eight minutes提问.in用于在某某时间内，该用how long 还是how soon？ 英语 小意思what a/what/how/how a在表感叹句有啥区别?in加一段时间和for加一段时间的区别?要有例子啊 我笨
