see through last decade great changes have taken place in our hometown采纳哟一定对那如果用witness呢？see through last decade great changes have been witnessed in our hometownsee在这里不是应该是见证，目睹的意思吗？In the last 10 years have seen great changes in our hometown.这样做错没错？错了.缺主语 这句话没主语只能用被动语态那就是 have been seen？对 great changes have been seen in our honetown好吧，谢谢！
