英语语法：Someone has been here. 为什么不是in here Someone has been in my office. 这里为什么又要有in?
答：如果你举的两个句子一个是be here, 一个是be in here, 则问题比较有深度.如果是be here 和be in my office,后者为什么有in,前者没有,则这个问题太浅了!因为初一学生都知道：come here, come to the blackboard.
get there, get to the office.
arrive here, arrive at the school
stay here, stay in the room
初中学生都知道,here是副词,其中包含了介词（in, at, on, 和to）的意思.类似的还有home: go home. go to his home.
至于stay here 和stay in here 的区别,及here的词性,我在别的回贴中有论述.Hi我,我给你个link.
再问： 新手不懂得HI 初中没学英语 大学过CET也没见多少有考语法 直接私信给我连接吧 The whole things began in the subway.A couple of weeks ago,I met a foreigner in the subway looking at the map,so i approached him and said hi and asked him if anything i can help,but when i point at a station on the map and said" we are in here",he ran away immediately and i was wondering if i am wrong.
再答： hi就是‘知道’中相当于QQ的一个东东。 一会在hi中给你这个链接。 英语语法：Someone has been here. 为什么不是in here 答: 因为here作为副词，本来就可以作表语，表示XX事物“在这里”。除非必要，不用in here. 如：Mr. Wang has been here for a long time. 王先生来这里已经有很长一段时间了。 in here也是有人用的。here的范围可大可小。in here则强调限定在一个相对小的范围之中，比如孙悟空要去找食物。用金棒在地上划了个圈，说：Stay in here! 我们说：They have been in here for three hours. Someone has been in my office. 这里为什么又要有in？ 答:因为这个inn my office 是介词短语作表语，表示XX人在XX地方。in表示“在。。里”。 如果没有这个in,则Someone has been my office. “人是办公室？”，这不合逻辑了。
再问： As i told you,we were in a subway station at that time,and my idea was to emphasize that we were "in"this station.If i meet another foreigner again next time,what am i supposed to use?
再答： 如果你要强调你就一直在这个地铁站里面，没有出来过，就可以用：I have been in here for a long time.
再问： 我强调的是在A站。。而不是在B站 原句是we are in here 指着地图和他说的。。
再答： 这是完全正确的。在这么说时，通常会伴随一个划圈的动作。
