题目内容：

Have been staying in Coventry for half a year,I accustomed myself to the life in British.
HAVE BEEN DOING这个语法高中学的,有点忘了

优质解答

Having been staying in Coventry for half a year,I accustomed myself to the life in British.
前面是分词短语,做时间状语.你写的那个不是非谓语形式.如果那样就要加上引导词和主语即,after I had been staying in .I accustomed.
