on average平均

例句:1.On average, I spend 100 on books each month.

2.But the study also found, on average, little or no effect on test scores in reading comprehension.

但是研究也发现,按平均来说,很少或没有影响考试分数在阅读理解上。

in average 平均地

例句:

1 .It shows that the increase in average mutual communication does not mean the increase in general correlation coefficient.

2.In addition, the change in average inhibition zone diameter may reflect the vicissitude of resistance to antibiotics in pathogens.

3.Scientists say even a slight increase in average temperatures could wreak havoc on farmers around the globe, as seasons shift, crops fail and storms and droughts ravage fields.

科学家表示,甚至平均气温略微上升,就可能会给世界各地的农民造成巨大损失,随着季 节发生转变,收成不佳、风暴和干旱等灾难将席卷农田。

从上面的例句中我们可以看出,on average 经常单独使用,做插入语。而用in average 时 后面一般跟有名词,这时的average似乎带有一点形容词的性质。呵呵,这两个短语意思差别不大,关键要放在具体语境里去理解。。
