1、 We have been studied English for 7 years.
2、 My mother has been ill for two weeks.
3、The door had been closed since they moved away.
4、The bridge has been built since 2006.
5、His parents were sleeping when he came home last night.
6、He had been waiting for one hour when the bus finally came.
7、He had been studied piano before he went to America.
注意：3、6、7题都是表示“过去的过去”,所以应该用had been的形式.特别是7题,意思是“在他去美国之前他一直在学习钢琴”,所以不难看出其时态的运用.
