英语复合句的问题不是说两个独立的句子之间不能用连词链接吗?比如说he is my father and she is my mother.这样说是不可以的呀,但是为什么我的范文上有这么两句话：The staff of the centre was well trained and high professional and the conference room was neat and spacious with an accommondation capacity of 1000seats and basic conference facilities.more than 300 companies attended and 100 plus national media units gave intensive coverage.这两句话里and连接了两个主语不同的句子啊?
