By turns与in turn的分别

 

两个介词短语都用来表示动作发生的次序,均表示“轮流” 的意思,但在含义和用法上有所差异。
in turn 强调轮流的范围较大,时间较长,而且在句中的位置比较灵活,而by turns一般位于句末。

By turns多用来强调某一时期内反复发生的动作,含有交替换用的意味,其中turns意为“交替(rotation)”,
意指「轮流地」、「交替地」、(one after another; alternately or in rotation);
例如: 
They sang song by turns. 他们轮流唱歌。 
Let's do this assignment by turns.让我们轮流做这个作业。
The shop assistants had to have their days off by turns. 店员要轮流休息。
We did the work by turns.我们是轮流做这项工作的. 
He gets cheerful and depressed by turns.他的情绪高一阵低一阵。


By turns常译为“交替,一会儿·····一会儿”。
如下面两例的“轮换”和“一会儿······一会儿”,实际上是AB交替的意思,一般不用in turn代替。
例如:
Both of them looked after the patient by turns.
他俩人轮流照看那病人。
The patient went hot and cold by turns.
病人一会儿发热,一会儿发冷。

in turn则指「依次相继地」。
例如: 
We sang the song in turn. 我们依照次序唱歌。
