some times later,some wolves really did come

应该是some time later吧,主要是区分sometimes,some time,some times,sometime的区别：
（1）sometimes的意思是“有时”,是副词.例如：
Sometimes he comes by bike and sometimes by bus.
他有时骑车来,有时乘公共汽车来.
（2）sometime也是副词,意思是“在某个时候”.可用于一般过去时与将来时.例如：
You can hand in your homework sometime before Friday.
你可以在周五前某个时候交作业.
（3）some time是名词短语,它的意思是“一段时间”.例如：
I'll be away for some time.我将离开一段时间.
（4）some times也是一个名词短语,time在这里用作可数名词,意思是“次数”.
some times的意思是“几次”.例如：
I have been to the Great Wall some times.
我去过长城几次.
