例子一:
如果这个房间为你们两人所共有,则应该说是“This is your & her room.” or "this room is for you & her." or "your and her room is this one"
第一种说法很少这样用,因为这不太符合英语的习惯,鼠疫不太正宗的英语.
例子二:
与第一种情况类似,
如果这些笔为你和我所共有,一般这样说:
“these pens belong to me & you.” or "these pens are yours & mine"
你的那种说法 理论上是正确的,但是一般不这样用.
如果这些你和我所拥有的东西是相同的:
these pens you have are same as mine,or your & my pens are the same.
