I have never been swimming.句子里swim后面要加的ing是因为be的存在?

I HAVE NEVER BEEN,能否说I never have been I have never been away! i have always been there i have never been there I Have Never Been To Me 歌词 I have never been away!什么意思? I have never been to me I have been never see this person . i have never been aboard 为啥 Because I never have been there before. -----i have never been to japan ----------- (n ) have i i have never been here还是i have never been in here 现在完成时中 never的问题I never have been there行不行?还是一定要I have never been there I have never been to Beijing.I have never been there，either.（改为同义句）I have never been to Beijing._______ _________.（两空） have never been是什么意思 never have I been there.的谓语是have还是never have. 同义句转换She has never been to England.I have never been there,either. I have never been abroad .He has never been abroad,either.的同义句 He has never been to new york .i have never been there,either.同义句
