请问一下，one by one 和one after anther 的区别！麻烦举例说明！谢谢！！！

one by one通常强调的是顺序，而one after another则强调数量.

例子:In 2001 the Chinese people were always in high spirits,for pieces of Exciting news came to China ___

A step by step
B one by one
C little by little
D one after another

选D 强调数量,指的是令人激动地消息之多。

one by one "一个接一个地"的意思，强调次序。

Let's do the exercises one by one.

one after the other adv. 相继地

one by one强调没有变化
one after one强调有变化

one by one 一个接一个强调动作

one after another (楼主打错了哦）

一个一个相继地
（强调状态）
