▼优质解答
答案和解析
这是一句被动语态句子,用了现在完成时态.由于你原句中没有“play”的行为主体,所以在转换成主动语态时需要加上一个行为主体,我们设该行为主体为任何某一个人或多个人:
1.I have never played this piano.
2.He has never played this piano.
3.You have never played this piano.
4.They have never played this piano.
5.We have never played this piano.
6.Our teacher has never played this piano.
例句够了吧.
1.I have never played this piano.
2.He has never played this piano.
3.You have never played this piano.
4.They have never played this piano.
5.We have never played this piano.
6.Our teacher has never played this piano.
例句够了吧.
