in the history,in history,1 In history,we have overcome one obstacle after another.-----在历史上,我们克服了一个又一个困难2 In the history OF OUR COUNTRY,we have overcome one obstacle after another---...不好意思，原来这问题没人踩我，我想问姐姐的，谢谢你啦，这两词没区别吗，还有用be in harmony with表示行为语言一致，咋说A IS in harmony with B-----语言一致,和谐不要加speech,saying吗sayingIS in harmony with doing -----语言一致,和谐-----言行一致
