初一英语题

l was having lunch with a friend in a restaurant.Sunddenly ,a woman shouted at us,"That table is (mine)!You can't sit there." I said ,"It 's not (yours)!we came first ,so it's not (your)table ." My friend said,"It's (ours)today because we are already eating our food here."
Then(the/a)waiter came ans said to the woman,"It 's(their）table today. They arrived before you."The woman was very angry and said,"well,which table can l have?"
Then he said to us，"She usually sits at this table,so she thinks it's (hers)"!Later,the woman shouted again,"Waiter, I have two bills!which is (my）bill?＂She pointed at us and added,"And which bill is (theirs）？"　We looked at the two bills,and the second one was (ours).
Then(the/a)waiter came and said to the woman.这句话waiter前的空应该填冠词a/the。你可以看下是不是抄错了。
另外，当后面直接接名词是，用形容词性物主代词：my,your,his,her,its,our,their。如：This is my bag.(这是我的包。)当后面没有名词，直接用于表示某人的某物时，用名词性物主代词：mine,yours,hers,his,its,ours,theirs。如：This bag is mine.（这个包是我的。）

mine,yours,your,ours,their,their,hers,my,theirs,ours.这些是形容词性的物主代词和名词性物主代词的区别。名词性物主代词=形容词物主代词+名词，所以就很容易选出答案了。加油哦^-^

是从上面选词填空吗？
mine;yours;your;ours
our(这个空不确定） ; their;
hers;my;theirs;our.
