英语名词+名词的问题
there was a dramatic increase in mobile calls from 2 billion to 46 billion minutes.The rise was particularly noticeable between 1999 and 2002,during which time the use of mobile phone tripled.我想请问一下time 和the use of中间不应该加个 of 手机使用的时间.
答
这样解释也许你就会清楚了.
结构应该是：The use of mobile phone tripled during which/the time.
可见：use和time在这里没有任何直接关系.
亲：高老师祝你学习进步,每天都开心V_V!

Merry Christmas!
