问题补充：
in turn这个词组怎么用法?字典里的解释是：one after the other in an agreed order,呵呵,这个解释的例句是：Each of us collects the mail in turn.是按顺序来的意思吗?另外还有个解释：in due order of succession,..还有一个句子：That in turn has led to a drop in the nations trade surplus for seven consecutive months ending April.
答案：
【答案】 in turn(指两人）轮流做某事；（指三人或以上）一个接一个地；接连的；依次;反过来.
如：they bought their tickets in turn.
他们依次买票.
Language is the carrier of culture and in turn is influenced by culture.
语言是文化的载体,文化对语言反过来起着制约作用.
That in turn has led to a drop in the nations trade surplus for seven consecutive months ending April
这反过来又导致了在全国连续7个月的贸易顺差在4月开始下降.
