请帮我看一下我的英语句子

It happened to a friend of mine a year ago.
可以换成：It happened to one of my friend a year ago.
你的句子也是可以的，但是多了一个 a :
It happened to my friend a year ago.

I have been quit my job for long time ago, so i've got no money.的语法有问题。所以不对。
应该是：I quit my job for a long time already, that's why I have no money.
或是：I had already quit my job for a long time, so I have no money.

一 不可以，a 和my不能同是使用
二 i quit my job long time ago,quit 是终止型动词，不和表示段的时间概念搭配

不可以吧。
It happened to one of my friend a year ago.
ago和短暂性动词连用
I have been quit my job for long time , so I've got no money.

It happened to a my friend a year ago.
第一句不能改成第二句，a和my不好放在一起吧

最后一句话的时间状语 for long time ago，for表示时间的持续，ago表示在一段时间之间，两个一起用不合适，你如果想说：不久以前我辞了工作，所以没有多少钱
个人意见，改成：I quitted my job long time ago, so I've got no money

把It happened to a friend of mine a year ago.
换成下面这句可以么？
It happened to a my friend a year ago.
回答：不可以 a my 不能搭配

这句话对么？
I have been quit my job for long time ago, so I've got no money.
quit不是持续的动作 不能一直辞职
应该为
I have been out of work for long time，so I've got no money.

当然可以呀

如果有什么不明白的，大可以问问你的英语老师

他/她还有可能会夸你勤学好问呢
